2012 Guangdong LED output value will reach 300 billion

Policy visibility

"Held by National Lighting LED series of standards Xuanguan, product certification and CCC certification of energy conservation and technology seminar" before the meeting read 11 lighting lighting appliances by the National Standardization Technical Committee organized the preparation of the national quality supervision and inspection and quarantine National Standardization Management Committee issued in 2008, 2009, 2010 the LED national standards and 1 industry standards.

Newspaper in Guangdong province quality supervision and inspection of special product senior engineer Li Zili, Xiamen Topstar Lighting Co., Ltd. senior engineer Qin Bifang detailed interpretation of the standard.

Li Zili said that the provincial government planning LED industry output 3 years tripled, to 2012, reaching 300 billion yuan, which is more than the 2009 national scale (5 million yuan) more lighting industry output, this indicates that the LED industry the opportunity to come.

The new regulations - fine solution

Safety requirements for LED modules for general lighting applications

LED module is the most difficult

"The bottom plate plus LED light source constitutes the LED module"

Li Zili said that the LED module can be made of different shapes of the bottom plate installed one or more LED light source, can also be composed of electronic machinery and other optical elements.

A floor and a LED light source module LED the most simple. Constant voltage, constant current, constant power, the outside of the control device, the constant power, this module does not have an integral control device. "Of course, to meet the requirements of this standard, but also add some protective devices, such as fuses, to pass this standard. Light source plus fuse plus module, which is the simplest. Li Zili said.

In safety standard range module, the provisions of the general and safety requirements for LED modules for general lighting.

Li Zili pointed out that the module scope includes two aspects: the work in the same current, the same voltage, the same power, the LED module with integral control device. In addition, the use of 250V or below 1000V DC or 50Hz AC power supply 60Hz or LED module.

LED heat is a thorny issue"

According to Li Zili, the most difficult problem of heat dissipation module LED. LED energy emissions without infrared radiation, therefore, how to ensure that LED heat, is a very difficult problem. Because LED basically rely on conducting wire heat, resulting in more trouble heat.

"If the heat is not scattered out, will lead to thermal expansion and contraction. He pointed out that to improve the heat, it is necessary to improve the performance of LED light source, especially to improve the optical power of LED and other blue chips. Second, is to improve the performance of the package. Packaging technology is very important, packaging materials, traditional resins, silicone - to reduce excessive reflection. Second, it is to reduce the thickness of the packaging material. In addition, increase the conversion efficiency of phosphor.

How to judge LED lamp is qualified? Li Zili explained that the heat resistance by the ball pressure test to test: the test temperature is + 5 DEG C, but the minimum is 75 DEG C, the indentation diameter shall not exceed 2mm. Fire by 650 degrees hot filament test to test: hot wire 650 DEG C, glow wire on the sample 30s.

In the judgment of LED lamp is corrosion, should pay attention to the use of the Aluminum Alloy. Here, Li Zili, for example, in the second half of last year, in Hainan Island, a seaside golf course, although the use of lighting is an international brand, but more than a year of corrosion. Because it uses the material is aluminum alloy. Therefore, especially in hot weather, hot climate zone to pay more attention to this corrosion resistance.

Performance requirements of self ballasted LED lamps for general lighting

The declared value is limited to the actual value range

"Self ballasted LED lamp life of less than 25000 hours, not qualified"

It is reported that, the provisions of the new GB: since the average life of ballast LED lamps should not be less than 25000h. Since the flow of LED lights in the ignition time of 3000h maintenance rate should not be less than 92% in the ignition 6000h, the luminous flux maintenance rate should not be less than 88%; at the ignition temperature of the rated life of 70%, its luminous maintenance rate of not less than 70%.

Li Zili explained that if the self ballasted LED lamp life less than 25000 hours, are substandard products, can not be listed for sale. However, it is not to say that the specific requirements of each LED lamp has such a long life, but on the same batch of manufacturers LED lamp life expectancy of the overall average. If a specific lower than this value is too large, you need to replace the manufacturers free.

"100W is not allowed to claim power, the actual only 80W"

In terms of electrical performance, the power factor should be consistent with the declared value. For example, you say that the power of the LED lamp packaging is 100W, but, in fact, the power of the LED lamp is only 80W, which is very kind. "

Li Zili said, in the LED power module, LED module with integral control devices work stably at rated voltage or rated current and frequency, the actual power consumption and the rated power of the difference is not greater than 10%. When the ballast LED module works stably at rated voltage and rated frequency, the difference between the actual power consumption and the rated power should not be greater than 15%.

"That is to say, if your LED light is self ballasted, so you claim LED lamp 100W, the actual power should be between 85W~115W. Li Zili said, if the actual power of your lamp is less than 85W or more than 115W, then your product is substandard products.

"Clearly marked, not cheating, blind random standard"

In identification, to
