LED lamps and lanterns reliability testing method - (AddTime -2013-03-06

Now the industry, LED by countless entrepreneurs are research and development production, and in engineering field and outdoor lighting has been occupies very important position, but when refining to household lighting, the market now can say is a potential shares. How can you change LED light source into ordinary families are numerous merchants have headache thing. Now let's discuss LED the future home lighting direction.

LED light source technology has been forming

The domestic LED lighting industry distribution is centralized, has initially formed in the pearl river delta, Yangtze river delta, southeast, Beijing and dalian, and other northern area four areas, each area basic formed a relatively complete industrial chain, dalian, shenzhen, xiamen, nanchang four area has LED mature production base.

On the one hand because of society to LED lighting is lack of sufficient understanding, on the other hand, because of LED lighting products, compared with the traditional lighting product of a higher price, LED permeability has been difficult to satisfactory. In march of this year, twenty, by the ministry of finance and the development and reform commission, ministry of science and technology organization "2012 semiconductor lighting products financial subsidies promotion project" in Beijing domestic public bidding, from all parts of the country's 110 enterprises of nearly 300 bid representative to participate in the bidding activities. Including used for indoor lighting LED downlight, reflective from ballast LED lamp, and used for outdoor lighting LED street lamp, LED tunnel lights LED products are classified as bidding products. The national development and reform commission made it clear that, in 2012, the Chinese government will spend 40 billion yuan for LED street lamp, LED street lamp to purchase 30% of the users of financial subsidies.

Overall, China's LED industry pattern south high degree of industrialization, the pearl river delta and Yangtze river delta is the domestic LED lighting industry the most concentrated area, in the middle and lower reaches of the industrial chain, a relatively complete, on the national more than 80% of the relevant enterprises. And the north is relying on many universities and research institutions, the product research and development strength is relatively strong.

Technology and the price is still the difficult solution of the problem

Although at present on the market of zhongshan ancient town has a small amount of household lighting businesses choose LED as light source, but always in a great deal of barriers, is still in a period of not perfect.

Encounter technology and equipment bottleneck. In the LED substrate material technology and epitaxial wafer production equipment, domestic LED lighting industry obvious bottleneck. Our country enterprise in the field of LED independent innovation and patent mainly concentrated in the packaging stage, and in most key of white light, the high power LED lamp heat balance problem, lasting and efficient fluorescent powder, etc., technology patent has been to Europe, America, Japan and other countries enterprise monopoly. The domestic LED lighting lamps and lanterns product brightness, heat dissipation, luminous efficiency and uniformity, antistatic resistance and leakage ability and quality control level and international product than there are still a large gap.

LED the lack of product pricing. The domestic LED enterprise scale is small, scattered industrial resources, core chip especially high power LED chip is mainly dependent on imported from abroad. A single small and medium-sized manufacturers can only single imported from abroad the high cost of the chip, resulting in the condition of low bargaining power, high cost. For individual families, 200W led Flood light and lanterns reflected energy saving is not clear how much money, cannot save. And 200W led Flood light and lanterns than ordinary lamps and lanterns is about three times more expensive, ordinary people can bear, is also a problem.

The lack of brand consciousness LED enterprise quantity is numerous, good and evil people mixed up, the product and time not neat, no independent brand, cause some patent stolen, tort events happen repeatedly.

LED household road shoulder heavy responsibilities According to the relevant departments of the guangdong province according to a report released by the United States, Japan and European LED enterprise, with more than 80% of the LED chip core technology patents, and domestic enterprises have the same kind of patent less than 10%. For a long time, LED upstream epitaxial wafer and chip market core technology, by foreign several big industry giants, such as Asia, Toyota synthesis, Cree, Osram and monopoly, occupy the whole industry chain 70% of output value, and this has LED the structure of the industry chain in our country is not reasonable. The author thinks that, although the incandescent lamp began to withdraw from the market for LED air out of the market, but such as acceptance price such bottleneck still restrict LED home lighting popularity. Of course, as the continued development of the LED technology and product quality continuously improve, into the family lighting is still the trend of The Times. Our LED lighting industry cannot blind optimistic, household lighting road heavy responsibities.
