General information: current status of the LED lamps downlight and the future direction of development

In view of the rising price of phosphor powder, the cost of ordinary energy-saving lamps rising, as the new lighting lamps LED lamps began to gradually into the public view. Since the birth of the LED lamp, the brightness of the continuous improvement, gradually from the LED lights into the field of LED lighting. LED downlight slowly from the high-end lighting upstart into the new market application.

The national development and Reform Commission since Chinese released "China phasing out incandescent roadmap", the roadmap provided from October 1, 2012 onwards, banning the import and sale of 100 watts and above ordinary incandescent lighting, and is expected to rise from October 1, 2016, prohibit the import and sale of 15 watts and above ordinary incandescent lighting, which means that the common incandescent lamp at China phasing out has been settled.

Since the birth of the LED lamp, the brightness of the continuous improvement, gradually from the LED lights into the field of LED lighting. LED downlight slowly from the high-end lighting upstart into the new market application. Downlight is generally used in shopping malls, offices, factories, hospitals and other indoor lighting, the installation is simple and convenient for people to love.

LED downlight downlight all inherited the traditional advantages, less heat, energy saving and long service life, small maintenance costs. The early LED lamp LED lamp due to expensive, the overall cost is very high is not acceptable to the customers.

With the decrease of LED lamp chip prices and cooling technology improved, laid a solid foundation for the LED lamp into the commercial field. The LED lamp LED lamp, lamp shell, and power supply.

The lamp downlight, should adopt high-power lamp as single 1W lamp, should not be used in small power such as 50505630 beads, the reason is that LED small power lamp brightness is bright enough but the light intensity is not enough, and the vertical distance is generally LED lamp irradiation of 4-5 meters, due to the small power light intensity enough ground light intensity is not enough, and high-power lamp especially integrated light source light intensity became the first LED lamp manufacturers.

Is widely used as a single 1W high-power lamp lamp, lamp made of 1W, 3W, 5W, 7W, 9W, the largest can generally be made of 25W, if the use of high-power integrated scheme can also make more power. Determine the life of downlight mainly has three parts: LED lamp, LED heat dissipation shell design [], LED power.

LED lamp manufacturers decided the main life LED lamp, the high quality chip foreign manufacturers have a CREE of the United States, Japan Nichia (Nichia), high performance Taiwan manufacturers EPISTAR (buy crystal electric LED chip package to the product, in Chinese refers to in Taiwan factory or packaging plant in the production of China on both sides of the main), billion light, the mainland manufacturers have enraytek optoelectronics optoelectronics, etc..

General quality LED lamp manufacturers, will use foreign chips such as the LED Cree, at least one of the high stable product market recognized. This makes the light natural high brightness, long life, but the price is not cheap, the use of the life of the Taiwan chip manufacturers are long, but the price is relatively low, basically acceptable to the Chinese market customers.

The local market China chip life is short and the light is large, but the lowest price has become a large number of small manufacturers preferred price. By adopting the LED lamp, LED chip is what kind of, but also directly determines the location and the LED lamp manufacturers industry has the social responsibility.

LED power is LED downlight LED downlight effect on the heart, life greatly. In general, LED downlight is 110-220V power supply, 220V power supply is Chinese local market. Due to the development of LED lamps in a relatively short time, the country has not the power supply standard, so the market LED power ring like hemitropous, uneven, a large number of low PF value, simply can not be flooded the market through the EMC power supply.

The power of the electrolytic capacitor life also directly determines the life of the power supply, due to the sensitive to the price, to find ways to reduce the cost of the power supply, the LED power conversion power is low, the service life is not long for LED lamp by "longevity lamp" to "short-lived lights".

Effect of thermal design of LED downlight on its life is also important. LED by heat conduction to the internal PCB lamp start and then exported to the housing, then housing by convection or conduction to the air.

PCB heat to be fast enough, thermal performance of thermal grease to be good enough, the radiating area housing should be large enough and reasonable design of several factors determine the LED lamp is in normal work of PN junction temperature not higher than 70 degrees, to ensure that the LED chip is in normal working temperature not because the temperature is too high too fast to produce light.

With the development of LED lamp technology change rapidly, much of the responsibility of the manufacturer has gradually realized the importance of the quality, the quality of the product can only accurately move customers to replace traditional light source and solution of the menace from the rear.

Shanghai Sheng Mei Electronics Technology Co., LED downlight quality determines the future development of downlight development, to effectively remove the shackles of LED downlight, must be in the quality of hard work, truly efficient lighting, more than 5W hours long life, truly impeccable quality products with light LED lamp in the future.

In addition to the quality assurance, the industrial design of LED lamp appearance improvement must also be put on the agenda. The future development of LED downlight in addition to the strict quality of customs, because the LED solid state lighting advantages relative to the traditional lighting more better creative appearance can choose other, must break the traditional ideas, truly LED downlight make the best use of it.

Give full play to the characteristics of LED such small heat can also be widely used in machinery and equipment and other equipment lighting. LED downlight is applied more and more widely, and the variety of the inferior LED lamp also flooded street, unstable quality expectations from time to time to break the new lamp.

Due to the lack of LED industry standard, consumers are unable to complain the low quality of the manufacturer, for the future development of LED lamp is covered with a thick layer of shadow. Is the market in the pessimistic wait and see or in the survival of the pressure to attack? Time will give us the answer, the answer is to rely on a large number of manufacturers have a sense of responsibility for the common.

In fact the introduction of new standards for development will help us a helping hand LED downlight, but also to the majority of LED manufacturers, do not order the immediate petty profits destroyed the overall development of LED downlight.

LED lamp's future is bright but we must aim high, after the spring will come sooner as a warning for the future.
