11 lighting LED 1 item of national standard and industry standard

Policy visibility

'stable cross LED lighting series of national standards, product CCC authentication and certification of energy conservation and technology seminar' held a few days ago, read out at the meeting of the state administration of quality supervision, inspection and quarantine national standardization management committee in 2008, 2009, 2010, has been compiled by the national lighting appliances standardization technical committee of 11 lighting LED 1 item of national standards and industry standards.

guangdong province product quality supervision and inspection institute senior engineer zi-li li, roth lighting co. , LTD xiamen Qin Bifang senior engineers for detailed interpretation standards.

zi-li li, said the provincial government planning LED industry output value 3 years tripled, to 2012, reach 300 billion yuan, that is, more than 2009 national scale ( 5 million yuan) Lighting industry output value more, this marks the prelude to the LED industry the opportunity came.

the new rules of fine solution ordinary lighting LED module safety requirements

the LED module heat the trickiest

'floor and LED light source, LED module'

zi-li li said that the LED module can be installed by the different shapes of floor above one or more LED light source, can also be composed of other electronic machinery, optical element.

a base plate and an LED light source constitutes the simplest LED module. Constant voltage and constant current, constant power, this provides control device, is a constant power, this module is not monolithic control device. ', of course, to conform to the requirements of this standard, but also add some protection device, such as fuse, to pass this standard. Light source and the fuse module, this is the simplest. 'Zi-li li said.

in the scope of safety standards of the module, the provisions of the general lighting light emitting diode module of general and safety requirements.

zi-li li pointed out that the scope of the module includes two aspects of content at the same voltage, current, under the same power to work, not to bring a integral control device of the LED module. In addition, is to use below 250 v or 1000 v dc below 50 hz or 60 hz ac power since the ballast LED module. 'Is a thorny problem LED heat dissipation,'

zi-li li said, LED module heat the most difficult problem. LED emits no infrared radiation energy, therefore, how to ensure the LED heat dissipation, is a very thorny problem. Because basically LED by wire heat conduction, which leads to the heat dissipation problem is more troublesome.

'heat if scattered not to go out, can lead to heat bilges cold shrink. 'He said, noting that want to increase the cooling, will improve the performance of the LED light source, especially the blue chips such as improve the LED light power. Second, is to improve the performance of the packaging. Technology is very important, packaging materials, the traditional resin, silicone - - Reduce too much reflection. Second, is to reduce the thickness of the encapsulation material. In addition, but also increase the conversion efficiency of phosphor.

how to judge whether the LED qualified? Zi-li li explain, heat by the ball pressure test to verify test temperature of + / - 5 ℃, but the minimum is 75 ℃, the indentation diameter shall not be more than 2 mm. Fire from 650 ℃ glow wire test to test 650 ℃ hot silk, glow wire on the samples of 30 s.

when determine whether leds corrosion, attention should be paid to the use of aluminum alloy. Here, zi-li li, for example, in the second half of last year, a beach golf courses in hainan island, although use the floodlight is a international brand is more than a year. Because it adopted by the material is aluminum alloy. So especially in hot weather, climate burning hot area to compare pay attention to the corrosion resistance.

'since the ordinary lighting ballast LED lamp performance requirements'

'declared value' and the actual value range co. , LTD.

'since the ballast LED lamp life less than 25000 hours, the unqualified'

it is understood that the new national standard stipulated in the since the average life expectancy of ballast LED lights should be not less than 25000 h. Since the ballast LED lights in the ignition point for 3000 h time maintain rate shall be not less than 92%; When the ignition point 6000 h, the optic maintain rate shall be not less than 88%; When the ignition point 70% rated life, its light to maintain the rate of not less than 70%.

zi-li li explained that if the ballast LED lamp life less than 25000 hours, it is belong to the unqualified products, are not able to go on sale. But, not to say that require specific each LED lamp is such a long life, but the manufacturers of the same batch of LED lamp life of the overall average requirement. If specific one is lower than this value is too large, you need to factory for free replacement.

'are not allowed to claim power 100 w, actually only 80 w'

in low power, power factor to comply with the declared value. 'For example, you declared in the packing of the LED lamp power is 100 w, but in fact the power of the LED lights only 80 w, it's very uncool. '

zi-li li said that in terms of power LED module, LED module without integral control device under the rated voltage or rated current and rated frequency stable work, the actual consumption of the difference between the power and the rated power is not greater than 10%. Since ballast and LED module under rated voltage and rated frequency stable work, the actual consumption power and the difference between the rated power should not be greater than 15%.

'that is to say, if your LED lamp is the ballast, so, you claimed 100 w LED lights, its actual power should be between 85 w and 115 w. 'Zi-li li said, if your actual power less than 85 w lamp or more than 115 w, that you of the product is unqualified products. Little pony
