Circuit analysis of LED ceiling lights power driver

 

LED ceiling lights manufacturers should be electronic, LED downlight is one of the most attention in recent years, LED lighting, the lighting design of LED-based light-emitting part of the drive control part and optical cooling structure design tripartite game.

 

The optical design of LED ceiling lights and radiator: LED downlight manufacturers should America, the optical design humane design of the LED downlights recently the rapid development of, or along the alternative route. The more appropriate LED to develop LED lighting products, thermal structure become more reasonable, more standardized module light source to reveal the advantage. New materials, cooling technology is launched, the cost will be further reduced.

 

LED downlight, the drive control: led high bay lights manufacturers should America that drive the conversion efficiency is one of the most effective solution. To improve power conversion efficiency, can reduce the power of the whole lamp, in the upgrading of the entire lighting efficiency, saving the cost of thermal design. Switching power supply before the demand for power factor does not have regulatory requirements, but the lighting of LED downlight and other countries to have a hard indicators. Reliability, increase in life is an important part. There are aspects of color temperature, brightness, intelligence is the future demand at a later time.

 

Light-emitting part: LED downlight manufacturers should America, LED downlight LED continuously improve the efficiency of chip light, LED energy saving controversy fade away. In the next few years, there will be further improved, laid a solid foundation for accelerated LED application, LED downlight design will become simplistic trend.

LED ceiling spotlights: must reduce the cost of production

 

LED ceiling spotlights: must reduce the cost of production

 

LED ceiling spotlights, LED panel lights is a great product advantage compared with conventional lighting, in addition to the superior characteristics of energy saving and environmental protection, the life of the LED panel lights and other lighting and more long, usually about 40,000 hours, LED panel lights. The prices are also lower. The basic need to replace about 10 years. This makes the LED panel lights in the market, attention has been paid.

 

From a performance point of view, the LED panel light is undoubtedly advantages are obvious, the greater its potential for development in the field of interior lighting, natural, but the current price of the LED panel lights, with the traditional lighting is still not at a level, so the LED panel light industry development requires not only strong promotion of the enterprise, but also inseparable from the support of national policy.

 

LED ceiling spotlights and lighting are fundamentally different, tungsten light source is a solar thermal products that convert electrical energy into heat energy, and thus the light-emitting products. LED lights are electronic products, it has a direct electrical energy into light, technology and materials prices remain high, the price of led high bay lights are gradually popular.

 

Decline in the price of the led high bay lights on the one hand need to rely on our advances in technology, on the other hand you need the support of government departments. The huge energy-saving advantages of LED lighting products, the future is bound to spread in China, which has become the consensus of the industry inside and outside.

 

RGB led downlight try to control the price into an average level

 

RGB led downlight try to control the price into an average level

 

LED Down Light is a new type of environmentally friendly lighting, compared with the general lighting, its advantage is undoubtedly more:

First of all, the long life of LED downlight, RGB led downlight price decreased, known as LED downlight lamps for longevity, because it is a solid cold light source, epoxy resin, light body and no loose parts, does not exist filament light and easy burning, heat deposition, the light fades and other shortcomings in the proper current and voltage, the service life of up to 60,000 to 100,000 hours, more than 10 times longer life than traditional light sources.

 

Second, compared with normal lighting technology, RGB led downlight lighting technology used in more environmentally friendly, because the LED is made from non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, can be recycled, its spectral no ultraviolet and infrared, neither heat nor radiation, glare, cold light source, can be safely touch, is a typical green lighting, led high bay lights price Gengshi Bi the same price more reasonable, which is the attention the main One of the reasons.

 

Also, LED is a tiny chip encapsulated in epoxy, very small, very light. LED Downlight power consumption is very low, because it is a DC drive, ultra low power consumption (single tube 0.03-0.06 W), electro-optical power conversion close to 30%. In general, the LED voltage is 2-3.6V, the operating current is 0.02-0.03A. This means that the electricity it consumes no more than 0.1W, the same lighting effects than traditional energy sources, nearly 80%.

How to improve the working efficiency of led road lights

 

How to improve the working efficiency of led road lights

 

The most direct way to improve the brightness of power led road lights is to increase the input power is bound to increase the input power in order to prevent saturation of the active layer must increase the size of the pn junction; junction temperature rise and thus make the quantum efficiency. Single-tube power increases depends on the device the ability to export heat from the pn junction to maintain the existing chip material, structure, packaging technology, the current density on the chip the same and equivalent thermal conditions, a separate increase the size of the chip junction area The temperature will continue to rise.

 

LED luminous efficiency is relatively low, causing the junction temperature rise, lower life expectancy. To improve life in order to reduce the junction temperature must be very great importance to the problem of heat dissipation. LED thermal design must start from the chip until the entire radiator, every aspect should be given full attention. Any aspect of poorly designed and will cause serious thermal problems. Led road lights in the long-term work in a lot of failure, more than half are caused by the lack of thermal design, the other half is caused by power failure. Therefore, the thermal design must be accorded full attention. With led high bay light efficiency is increased every year, the heat problem will be gradually reduced. I believe that one day we will see the emergence of LED lamps do not need the radiator!

 

Carbon reduction trend, driven by the LED lighting is the trend of non-file, and cooling technology, progress is more relevant to the popularity of speed and range, one can imagine, the future and more advanced cooling technology will continue to promote LED comprehensive lighting soon.

Factors affecting high-brightness led vehicle lighting

 

Factors affecting high-brightness led vehicle lighting

 

With the increasingly urgent demand for LED lighting and environmental pollution, the led vehicle lighting with its energy-saving and environmentally friendly features have a broad application space, the application of led vehicle lighting products in the lighting field is attracting the world’s attention. In general, the LED lights work stability, the quality is good or bad, and the lamp cooling is essential, the heat of the high brightness LED lamps on the market, often using the natural cooling effect is not satisfactory. LED lamps, led high bay light source to create LEDs, thermal structure, drives, lens, so the heat is also an important part, too high a temperature will cause the LED luminous efficiency of attenuation; the waste heat generated by the LED operation can not be effectively shed, directly caused by the fatal impact on the life of the LED. Therefore, the LED heat dissipation is the most important issue in the design of the LED lamps.

 

Thermal management is the main problem in the high-brightness LED applications

P-type doping of III-nitride limited by the solubility of the Lord and hole higher than that of Mg activation energy and heat are particularly vulnerable in the p-type region, and this heat through the entire structure must be dissipated in the heat sink; LED the thermal path of the device is a thermal conduction and convection; Sapphire substrates is extremely low thermal conductivity of the device thermal resistance increase, resulting in severe self-heating effect, have a devastating impact on device performance and reliability.

LED planting lights: make the growth of plants perfect

 

LED planting lights: make the growth of plants perfect

 

Education agencies, public utilities, industrial and manufacturing enterprise, transportation, and agriculture-all these effects without lights. Do not contain any artificial lighting can also don’t do any one sector of economic development. At present to replace the standard incandescent lamp, fluorescent lamp, mercury, sodium lamp with bright LED planting lights have increasingly lamp. The trend as the transition to led can clearly see in modern industry and agriculture.

 

In the eighteenth century, scientists found the process of photosynthesis. Photosynthesis: this process is plant of the main activities of the responsible for their growth and development. The office of photosyn thesis-the most efficient way to affect productivity and production plants. Russian scientists Timiryazev proof, energy is mainly has the photosynthesis part of the spectrum (red), and the effect of short-wavelength (blue) is not significant.

 

At present, illustrates the application of plant for crop high pressure sodium lamp. We all know not with sodium lamp, short-lived. The modern leadership fit lamp plants can provide more relevant range of agricultural light spectrum of photosynthesis.

 

Where can you buy, you how to use LED planting lights?

 

Led high bay lamp plants and herbs, used in our diet and grown in windowsill or in the balcony: oregano, thyme, parsley, dill, basil, and so on. Fit lamps used for lighting indoor plants, should be implemented from the beginning of winter to the well to draw a perfect result. It is also an indispensable greenhouse grow vegetables in personal, family and industrial scale. Lamp or E27 PAR38 leadership leader-ship position is very convenient at home, because this is designed for voltage 220 V, make into a normal light socket E27 into.

 

 

Price competition for led street light bulbs

 

Price competition for led street light bulbs

 

Governments planning, the era of the incandescent exit lighting industry in the next decade, governments around the world are actively promoting the energy efficient lighting products, energy-saving lamps and led street light bulbs will compete for the lighting products market. With the rapid development of LED industry, the production efficiency, chip luminous efficiency increased dramatically, LED lighting product prices will drop quickly.

 

DRAMeXchanger’s research department LEDinside latest led street light bulbs retail price survey shows that following the retail price of LED bulbs dropped sharply in December 2011, in January this year (2012), the overall average retail price of led high bay bulbs continued to decline steadily, replace 40-watt incandescent bulbs, the average international price of $ 19.6. South Korea, the most intense price competition in first-line lighting brands introduced to replace 40W incandescent bulbs products terminal price has been under the killing to below $ 10. Replace the traditional 60-watt LED bulb part of the international average retail price of $ 35.4, only South Korea, the emergence of low-priced below $ 20.

 

Commodity prices to replace the traditional 40-watt incandescent bulbs, the average decline of nearly 7 percent in January. South Korea remains the most competitive region, the average retail price of $ 10.4, down 13 percent, the minimum price of about $ 8.2. In addition, the Japan region only one percent of the decline did not continue the substantial decline of the previous quarter, mainly due to yen appreciation, therefore translated into U.S. dollars decreased, coupled with LED bulbs in Japan has decreased.

Henan LED household lighting market: high prices start to drop

 

Henan LED household lighting market: high prices start to drop

 

LED surging tide come from outdoor to indoor, more widely, the price way down, had the closer to the average consumer; dealers are adjusting their business direction, more or less the increase in the LED household lighting products, LED from the first outdoor more and more commercial infiltrated the home decoration, and slowly evolved into a home improvement of essential goods. The beginning of the Henan conference Foshan LED lighting products, even the panels displayed at the site and sample are impatient dealers to take away, fully illustrated to County acceptance of the market for LED household lighting.

 

Lighting general manager of Eagle Tian Wang Li: the development of the led high bay lighting market to a corner, the market acceptance is very high, as prices continue to decline, the home field of application to become a big growth points. Lighting time in the engineering field, far more than the home, energy-saving effect is more pronounced, longer life, the benefits are obvious, being sought after is a matter of course.

 

President Chen Xinxiang Rainbow Lighting: LED household lighting used in the crystal lamps, candle lamps, luminous efficiency and good, but due to its small size, the finishing point effect, long life, energy saving for the customer to buy these high-end products LED and conventional light sources, the price difference is not particularly sensitive to the effects of most concern to the whole lamp.

 

Yanli were sent Henan logistics providers: Beginning last year, the LED wholesale large, more and more retail, especially in 1W, 3W of generally accepted by consumers.

Two factors to affect the domestic LED lighting market

 

Two factors to affect the domestic LED lighting market

 

1. the lack of national standards

Of the lack of LED (domestic LED lighting) products of national standards, lack of standards for quality certification, a direct result of the quality parameters of products on the market

Poor heartbeat, confusion in the market, product and market are the lack of uniform standards to measure and norms, which affect consumer confidence to buy. But also because of the lack of national standards, can not be quality certification for leveraging policy support to the development of domestic LED lighting industry, it means not into the list of government procurement, the loss of a large market for government procurement. Therefore, the lack of national standards as a constraint to product continue making. The main problem of the exhibition.

 

2. the price is too high

The real market for the domestic LED lighting, commercial lighting, industrial lighting, road and outdoor lighting should cover a number of areas, but now the led high bay lighting industry is mainly in a international style. Sales market or public areas, large areas, but in such demand for home lighting applications the least. China’s energy-saving lamps domestic LED lighting prices are too high, according to market conditions, 3W LED energy-saving lamps sold at 80 yuan, the price is equivalent to the ordinary energy-saving lights five or six times higher incandescent lamp 10 times. And so the price can not be accepted by ordinary families. Price as a constraint to LED energy-saving lamps in China.

Another key issue in the field of home lighting.
