Analysis On The Development Of Led Lamps And Indoor Lighting Requirements

Analysis on the development of LED lamps and indoor lighting requirements by carollgushee

LED flood lights market opportunity is huge, broad space for development. LED lighting application from development to indoor outdoor landscape lighting LED lighting applications in the past. According to the analysis of LED lighting development within the next five years will be an exponential growth trend. 2011, its output will be up to tens of billions of dollars. 2009 the EU take the lead in implementing in particular disabled incandescent plan, concern and energy saving issues, creating a huge market opportunity and optimism LED interior lighting of the future.
Development of high power Blue LED strip depends on two major elements: one is the chip itself; second, lighting technology, include thermal, optical, driving. First of all is the chip, at present, the LED chip substrates and epitaxial growth of materials is the key to the development of technology. Scaffold from a traditional blue sapphire material, Silicon, and silicon carbide, to the development of new materials such as zinc oxide, gallium nitride. LED network of excellence is the focus for the lighting and general lighting high power chip, is also used for decorative lighting and some simple auxiliary lighting and low-power chip, technology upgrading critical about how to develop more efficient and stable chip. In just a few years, with the help of included device structure, surface roughening process and multiple-quantum-well structure design, a series of technical improvements, LED luminous efficiency to achieve quantum leaps. Thin film chip technology is at the heart of super bright LED chip production technology, reducing the light output losses on the side of, and with the help of 97% above a reflecting surface at the bottom of the light from the front output. This not only significantly improve the efficiency of LED, lens design creates a superior accommodation.

Actually from LED panel of development yilai people has been concern it of using life, if just relies on using low heat resistance of LED components is failed to for lamps device construction good of thermal system, and must effective to reduces from PN node to around environment of hot resistance, to greatly reduced LED of PN node temperature, and success practice extended LED lamps of using life and improve actual flux of target. LED network of excellence than conventional lamps, PCB is LED-powered carrier, also LED the heat carrier, so the heat sink thermal and printed circuit board design is very important. In addition, lighting manufacturers also need to consider the heat sink material quality, thickness and size as well as factors such as thermal interface and connections.

Optical design of LED lighting, compared with traditional lamps, directional and point lights are the most typical characteristics of LED lighting key optical design department. By binary optical design LED, LED lamps can achieve better light distribution curve. As the current largest indoor LED lighting application development market lighting needs very bright light, high light transmission rate of shade can be used to improve light extraction efficiency. Or the application of Lightguide technology to lighting, which changes the LED dot light source to light, not only can improve light distribution uniformity of the lighting, also prevents glare. Can also be used with some focusing lens or reflector to highlight the concentrating effect of illuminating objects for practical ideal optical effects.

High power LED lighting technology challenges, even if LED Interior accent lighting and decorative lighting has been a satisfactory performance in the application, but in General still faces many challenges in the lighting and mood lighting applications, including the replacement cost, lower color temperature of light effects, color-rendering index and system reliability. Cost is relatively sensitive factors in indoor lighting, especially in home lighting applications. Although the models more and more LED lights, luminous efficiency is constantly increasing, but prices are high the problem still exists. But when the price of LED light source reduction, optimization of overall system design, the total cost will surely fall. LED excellence network

LED lighting improve the photosynthetic efficiency of low color temperature when low color temperature of 4000K Interior home lighting is usually preferred. Warm white light makes the environment more warm and relaxed and Leng Baiguang you give people a feeling of clean, efficient and bright, more suitable for Office and outdoor lighting. Extended service life of LED lamps, improving system reliability. General lighting applications, the overall efficiency, service life and reliability of the LED must be optimized to be enhanced by system. LED networks of excellence LED lighting: Compact, high performance, a variety of color and output choices. Power: AC, battery and other power supply converts the high security and low-voltage, constant-current power supply. Control and drive: using electronic circuits LED constant current driver and control. Thermal management: to achieve a longer service life, control LED temperature node is very important, and thermal analysis are also indispensable. Optics: lens, reflector or light guide material are optical components of light focused on the target area may be necessary.

With the rapid development of LED technology and LED lighting effect increased gradually, LED the increasingly widely used. Especially with the increasingly serious global energy shortage, people more and more attention to the development of LED lighting market prospects, LED is the potential of replacing incandescent, tungsten and fluorescent light. In addition, in terms of interior lighting design, LED the trend of energy conservation, humanity and art.

Led Foreign Trade Situation This Year?

LED foreign trade situation this year? by carollgushee

For the Chinese market, 12v LED to lift the term is more and more high frequency. In China the Government has begun to promote LED, local financial subsidies have come down, promotion is achieved. But because people are not what led energy-saving effect, one-time impact of inputs is too large and traditional lamps, LED the situation is not very widely used in China. But in other countries, foreigners pay attention to clean energy and environmental protection, on LED energy-saving environmental protection effect is good, less maintenance and longer service life and so on merits, or overseas market is considerable. Bulb prices downward trend, in 2011-2016 years, LED light on traditional lighting into millions of households.

LED flood light industry is divided into upper, middle and lower reaches, upstream: chip manufacturing, equivalent to the traditional tungsten wires for lamps, in the whole industry chain in a core position; Middle: encapsulated device, equivalent to the traditional lighting of capillary; lower: assemble the lamps. Many enterprises are the middle and lower reaches of industry in China, imported Wick processing package, and then the finished product exported. LED patent technology in the world is concentrated in Japan and Europe, 5 companies, and Japan the most patent barriers and trade protection in some countries. So if you really want to achieve the maximum profit of enterprise in China, you must have the core technology and processing technology of double benefits, restructuring and technological innovation.

When it comes to foreign trade, have to say e-commerce. When it comes to e-commerce, Alibaba, the had to say. But today LED foreign trade did not say Alibaba. We are tired of saying it, I have nothing to say. LED foreign trade said today, I recommend a platform was founded by Hong Kong International procurement assistance LED to the international marketplace.

Why choose the platform? There are three reasons why:

First of all, they are an independent platform focused on the LED industry, their team was also LED strip lights the industry, I feel their customer service is very professional. At present, such a platform not more.
Second, they are a member of a nanny service, mainly to do not what to do foreign trade companies, on the form of a dedicated teacher of foreign trade. We are joint members, level not as advanced as nanny.
Thirdly, we are for sending inquiries both in Alibaba, the foreigner is treacherous, we can't. But this platform was not a foreign service to the US, inquiries of them one-on-one, he is talking a good few customers. I think why, mainly effects, this is very important to our business.

But one might ask, how do you know if they, did so good? So is worthy of investment, personal recommendations are: the negative and fully affirmed is inappropriate. Wise move is to first understand and then decided to see if their introduction is in need of, certainly not customer service said that what you believe in. You can look at their dynamic, is heading in a positive direction. And then go to the pilot on the platform, publishing product information, some platform operation skills, can go online to look at. Such an approach is safer.

Led Ceiling Lights And Spotlights A Different Place

LED ceiling lights and spotlights a different place by carollgushee

LED ceiling lights and spot lights, many people are confused, don't know that what is the difference between two types of lamps, what do you want to apply to the home position, application and effect of the difference. Simply put, LED ceiling lights is a relative to the normal state with the lighting of lamps of more concentrated, usually used for general lighting or auxiliary lighting. Spotlight is a highly concentrated light, its light is to specify a specific goal. Is mainly used for special lighting, for example, emphasizes a lot of flavor or is it a new place.

We come from the following aspects distinguish LED ceiling lights and spot lights.
1, look at the LED smallpox shoot lamp can fit into incandescent or install energy-saving lamps. When installation of incandescent lamps are yellow. Installation of energy-saving light bulb types can be white or yellow. Smallpox LED smallpox shoot lamp light direction is not adjustable. From the diagram we can see the LED smallpox shoot lamp of energy-saving lamps, and waterproof LED smallpox shoot lamp is on the outside and a waterproof glass cover. General Household lights using a quartz bulb or lamp beads. Of course, large spotlights are not necessarily quartz bulbs. Quartz bulbs only yellow light. And the spot light lamp with adjustable light direction.

2, the application from the LED smallpox shoot lamp were installed in the ceiling, ceiling requires more than 150mm can only installed. LED ceiling lights also have an external type. In areas where no ceiling lamp or chandelier installed LED ceiling lights are a good choice, light relative to the spotlight to be soft. Spotlights can be generally divided into tracks, hanging type and embedded type and many other. Lights with transformers, but there are no transformers. Built-in spot lights can be mounted on the ceiling. Lights are mainly used for emphasis or performance, such as video walls, paintings, jewelry, and so on, can play light classics to enhance the effect.

3, led lights on the price of the same grade, Spotlight more expensive. Generally better quality of domestic LED smallpox shoot lamp Spotlight brand opeal, sanli, Lei Shi, three male Aurora. Among them, Lei Shi and sanli the best cost-effective. LED ceiling lights are generally large (5-inch) (4) small (2.5-inch) three. Trumpet the current market price of between $ 20-15, a medium between $ 28-32, tuba between between $ 36-48. Above prices are not inclusive of light sources, of course. Plug the LED smallpox shoot lamp horizontal and vertical plug two, horizontal than vertical plug plug price would cost a little.

Are to be noted in, lights are generally not used for brachytherapy wool fabric, or near flammable obstacles, otherwise easily lead to fire. Although Spotlight power in an appropriate location has its decorative effect is quite different. Spotlight also has five Carnival glass decorated proceed.

Led Drive Power Of Selected Aspects Of Design

LED drive power of selected aspects of design by carollgushee

As the Ministry of science and technology "ten cities" project starts, LED lighting has once again set off upsurge in emerging industries. At this point, companies have joined the industry LED industrial development has helped the entire industry chain has grown. Development of LED lighting industry very quickly, in addition to energy-efficient, it also has the advantage of more, and deliver new and unprecedented lighting solutions.


In the area of LED drive power, now as the industry leader of Mau master the development road of power Corporation in Shenzhen, was legendary. Out of sense of smell in the LED industry, Mao helm Gu Yongde master power led his team in 2006 and began research and development of LED power. Today, the Mau master power the world's leading technology has lead the trend of LED street lamps Intelligent drive, made for LED Street lamp intelligent driving solutions for manufacturers to provide the most reliable, which is a leading example.


LED driver power supply power


LED power supply as a core part of LED lights, LED by heart, a direct decision of the LED drive power LED lighting is good or bad.


First of all, in structure design, Outdoor LED drive power must have a tight waterproof function, otherwise, cannot withstand the outside harsh environment; the waterproofing process requirement and irrigation requirements make the glue adhesive technology, currently Mau Shuo glue technology makes the product waterproof to IP68 level.


Second, the LED drive power supply lightning protection feature is also vital. Outside work are bound to experience thunderstorms, if the power supply is no lightning protection function, will directly affect the LED lamp life, increase lighting maintenance costs;


Finally, on the selection of raw materials, their reliability must meet their life needs, functions and features you want is good enough. Theory of LED chips now life is about 100,000 hours, and component longevity in the industry if you want to match, selection of key components must be perfect DMT, DVT-proven management, to ensure long life and reliability requirements, otherwise life enough power, lamp life expectancy cannot be achieved now Mau master power over life of up to 50,000 hours.


Therefore, LED power supply reliability is the basis for supporting LED development, LED drive power in energy-saving, high performance, longer life than traditional lamps, LED can truly save energy, promoting industrial development.

Led High-power Street Lamp Technology

LED high-power Street lamp technology by carollgushee

LED street lamps to large-scale application, the general notion that still needs some time,. but I really think that LED lights technology matured. Welcome to correct me.

To say LED street lamps (which is actually all LED lighting) is not reason for large-scale application are the following three:
1, LED street lamps light efficiency has not yet reached to the level of sodium;
2, the life of LED street lamps;
3, LED street lamps photometric is not ideal.

Talked about LED street lamps, many people will pointed out that LED of display color index LED controller than sodium of display color index high many, and can reduced LED street lamps of as of standard, appeal separate for LED street lamps amendment standard, actually, from macro Shang see sent hope Yu amendment standard is does not reality of, and I think existing of road lighting standard no may also no necessary amendment. to makes LED replaced other light became reality, on only by LED lighting area of people themselves efforts has.

Luminous efficiency problems:
First, sodium of light effect does is high, I see some better of sodium products units power lumens number are in 110 above, and currently do of good of LED also on in 90Lm/W around, also no energy saving. but, if comparison lamps of efficiency, conclusions on does not as has. because general light are is 360 of Omni-directional uniform glow, and LED glow has directional, usually is 180 of within, so difference, Street light is not the same. made of sodium lamp or conventional light Street lamp lamps light efficiency is typically around 60%, LED street lamps can more easily reach 90%. According to the weighted, effective light for the 66Lm/W sodium street lamps and LED Street lamp light can effectively reach 80Lm/W.

Second, since it is a street lamp, is of course the only fall on pavement of light is needed, that will further see the flux on the road, to minimum national standards H=Weff, for example, better utilization coefficient of sodium lamps of 0.3,[url=http://led8989.bmlink.com/]LED controller [/url] if LED utilization coefficient of 0.8, then to the current level of LED luminous efficiency, A 110W of LED street lamps on full can replaced 250W of sodium has, if considered to actual engineering cost, factors, usually in accordance with H=1.2Weff to design words, to 100W of LED street lamps replaced 250W of sodium is at this stage on can implementation of. to reached 60% so of energy saving level has has enough of energy saving effect has. to reached 0.8 of using coefficient, this is see LED street lamps design personnel distribution light of Foundation, actually is also does not difficult.

Life issues:
If was told you, they of LED lamps of life has 100,000 hours or 50,000 hours, and 30,000 hours, you and to hear is not to believe, but remember asked asked how are of, if said is known of, that you heard had even has, if told you is measured of, must then asked about is to how many hours data for Foundation of, because now certainly no anyone for had to million hours for meter of test, because this impossible, future also does not has foolish for so of test, Because it's not needed. 1000 hours of data will tell you, you don't count, because a lot of LED tube luminous efficiency is increased in 1000 hours. LED controllers and of course, when you tube as well. Now international passage of life test time is 1000 + 5,000 hours test, yiqian 1000 hours for stability time, Hou 5,000 hours data for calculation life of pursuant to, over 5,000 hours life in accordance with 5,000 hours within of intended-in curve outside push calculation. we actual test of 1+5 thousand hours of light failure for 2.2%, and is linear of, if considered some allowance, we will products standard will for 5,000 hours light failure for 2.5%, so outside push 50% light effect of life will is 100,000 hours, 70% Photosynthetic efficiency of life expectancy of 60,000 hours.

But, regardless of is in accordance with 50% also is 70% calculation life are is does not important of, actually most science of is for many national by used of method is maintained as of does not below standard provides of maintained as of of life for quasi. such as GB provides fast road of maintained average as of for 20Lx, if early loaded street lamps of average as of for 30Lx, is should to 66% light effect calculation life, so calculation of life is is 66,000 hours. LED controller if plus midnight lamp control, Real time on up to 100,000 hours. of course, can we really achieve this time, may have to wait 25 years before you can know.

Improve The Thermal Structure Of White Light Led Life

Improve the thermal structure of white light LED life by carollgushee

Past led industry who to profit full of white light LED beam, had development large size LED flood lights chip tries to by this way reached expected target, but actually white light LED of imposed power continued over 1W above time beam instead will fell, glow efficiency is relative reduced 2030%, in other words white light LED of brightness if to than traditional LED large number times, consumption power characteristics hope beyond Firefly light lamp words, on required first overcome following of four topics, including, suppression temperature rose, and ensure using life, and Improvement of luminous efficiency and photoluminescence of equalization.


The problem of temperature rise of the specific method is to reduce the thermal resistance of the package; maintenance of Blue LED strip the life of a specific method, is the improvement of chip shape, small chip; improving the LED luminous efficiency of specific measures is to improve the structure, a small chip chip; improvement of luminescent characteristics of uniform methods is LED packaging methods, and in the development of these methods have come to be.

Thermal problem is the fundamental way to solve package

Due to increased power instead will caused package of hot impedance sharply fell to 10K/W following, so abroad industry who had development resistance high temperature white light LED tries to by this improve above problem, however actually power LED panel of heat is than small power LED high dozens of times times above, and temperature rose also will makes glow efficiency sharply fell, even package technology allows high heat, but LED chip of junction temperature is has may over allowed value
Finally finally learned to solve thermal problems is the root of the package.

About LED of using life, such as instead Silicon mass package material and ceramic package material, can makes LED of using life improve one number, especially white light LED of glow spectrum contains wavelength below 450nm short wavelength light, traditional epoxy resin package material very easy is short wavelength light damage, high power white light LED of large light volume more accelerated package material of bad of, under industry who test results displayed continuous light does not to 10,000 hours, high power white light LED of brightness has reduced half above, Does not meet the basic requirements for lighting and long life.

About LED of glow efficiency, improve chip structure and package structure, are can reached and low power white light LED same level, main causes is current density improve twice times above Shi, not only does not easy from large chip out light, results instead will caused glow efficiency than low power white light LED of dilemma, if improve chip of electrode constructed, theory on can solution above take light problem.

Seeks to reduce the thermal resistance, improve the heat sink problem

About luminescent characteristics of uniform, General believes that improving the concentration of fluorescent white light LED material uniformity and fluorescent technology, should be able to overcome these problems. As mentioned above while improving power imposed, must try to minimize thermal impedance, improved heat dissipation, and specific content in the report are: reducing the chip to the thermal resistance of the package, contain the package thermal resistance, improve the chip to printed circuit substrate heat sink of smooth.

To to reduced hot impedance, many abroad LED manufacturers will LED chip set in copper and ceramic material made of thermal fin tablets (heat sink) surface, received s then with welding way will printed circuit board Shang thermal with wire, connection to using cooling fan forced empty cold of thermal fin tablets Shang, under Germany OSRAM Opto Semiconductors Gmb experimental results confirmed, above structure of LED chip to welding points of hot impedance can reduced 9K/W, about is traditional LED of One-sixth around, package Hou of LED imposed 2W of power Shi, LED chip of junction temperature than welding points high 18K, even printed circuit board temperature rose to 500C, junction temperature at most only 700C around; phase than Xia past hot impedance once reduced words, LED chip of junction temperature on will was printed circuit board temperature of effect, so then required managed to reduced LED chip of temperature, in other words reduced LED chip to welding points of hot impedance, can effective reduce LED Chip cooling burden of the job. Contrary even white light LED has suppression hot impedance of structure, if heat cannot from package conduction to printed circuit board words, LED temperature rose of results glow efficiency will sharply fell, so Panasonic electrical development printed circuit board and package integration technology, the company will 1mm square of Blu-ray LED to flip chip way package in ceramic base board Shang, received s then will ceramic base board paste in copper mass printed circuit board surface, under Panasonic said contains printed circuit board zainei module overall of hot impedance about is About 15K/W.

Show thermal design power

Due to thermal fin tablets and printed circuit board Zhijian of key s sexual directly around hot conduction effect, so printed circuit board of design became very complex, has prison Yu this United States Lumileds and Japan CITIZEN, lighting device, and LED package manufacturers, have development high power LED with simple thermal technology, CITIZEN in 2004 began samples shipments of white light LED package, does not needs special junction technology also to will thick about 23mm thermal fin tablets of heat directly emissions to external, under the CITIZEN said although the LED chip junction to heat thermal impedance than the OSRAM 9K/W fin 30K/W, and in general the environment around room temperature will increase the thermal resistance under 1W, however even traditional printed circuit boards without the cooling fan under forced air cooling, the white light LED modules can also use continuous lighting.

Lumileds high power LED chip began sample shipments in 2005, junction allowed temperature is as high as +1850C, 600C higher than similar products of other companies, when using traditional RF4 printed circuit board packaging, the ambient temperature can enter 400C range 1.5W electric current (about 400mA). So Lumileds and CITIZEN makes take improve junction points allowed temperature, Germany OSRAM company is is will LED chip set in thermal fin tablets surface, reached 9K/W super low heat impedance records, the records than OSRAM past development sibling products of hot impedance reduced 40%, worth a to is the LED module package Shi, used and traditional method same of flip chip way, but LED module and hot fin tablets junction Shi, is select most near LED Chip layer as the land, take the light layer to provide short-distance transmission of heat emission.
