Guangzhou LED module sampling pass rate of 100%

According to the Chinese quality news network reported that recently, the Guangzhou Municipal Bureau of quality and technical supervision for the supervision and checking of the production field LED module product quality, a total sample of 4 enterprises produced 6 batches of products, testing all meet the standard requirements.

The spot checks on the basis of GB/T 24823-2009 general lighting with LED module performance requirements and other standards, the power factor, power, the initial light effect and other items for inspection.

The purchase of LED module products to choose well-known, authoritative agencies announced qualified brand. The overall quality of large enterprise products, information tagging accuracy, customer service service in place, especially some domestic brand-name products, reasonable price, quality and foreign brands, the price is high, suitable for the majority of consumers.

Initial luminous efficiency. Pay attention to the initial value of light on the product packaging, the higher the initial luminous efficiency, indicating that the better the energy saving effect. At present, the initial 100lm/W value of good LED products can reach more than.

Dissipate heat Although the LED light source is a cold light source, a large amount of heat will be generated inside the chip. In the purchase, should observe the appearance of the shell, smooth and smooth can be preferred. At the same time pay attention to observe whether there is a corresponding thickness and surface area, because the heat is mainly from the heat sink.

Drive. As the driving force of LED lamps, it is very important. Related to the problem of LED driver, you can consult a variety of businesses on the driving parameters, such as output voltage and current, power factor, operating temperature, etc.. 3.2V 1W working voltage LED bulb, working current is about 320mA. If the current is too large, it is easy to make the lamp pearl decay intensifies, shorten life. If the drive power factor is too low, such as 0.6 power factor, 10W lamp, it is necessary to consume the power of 16W. At the same time, the power factor is too low, which naturally led to the increase in the heat of the drive itself, and electronic components are most afraid of being heated, heating means that the increase in the temperature of electronic components themselves, prone to quality problems.
