Tags: LED, light decline, resolve way
LED light product failure is the light in the transmission signal weakened,
And at the present stage of global LED manufacturers have made the extent of bad light LED products are different, Similarly the existence of high-power LED light failure, which is directly related to temperature, mainly by the chip, phosphor and packaging technology decisions.
At present, the white LED market decline of its light may be illuminated to the civilian one of the first questions to enter. LED light for the decline mainly in the following two factors:
First, LED quality of the product itself:
1, used in bad physical grain LED brightness decay quickly.
2, the existence of defects in the manufacturing process, LED grain heat can not be good derived from the PIN feet, resulting in LED chip die temperature is too high so that the attenuation increased.
Second, the use of conditions:
1, LED constant current driver for some reason LED drivers enable the use of voltage attenuation from LED.
2, drive current is greater than the rated drive conditions.
In fact, lead to bad light LED products for many reasons, the most critical issues or hot, even though many manufacturers in the sub-product is not a special focus on the problem of heat dissipation,
However, these sub-products for long-term use of LED, light failure have focused on the degree of heat than the LED products is higher.
LED thermal resistance of the grain itself, the impact of silver plastic, the thermal effects of substrate, as well as colloidal and gold are also related to bad light.
Our main products include lighting fixtures and ceiling light fixtures, which are widely used in home & office, for commercial and industrial purpose as well. Please refer to www.acmelite.com for more details. From 2007, we developed two new product lines: Solar Power Light and LED light. We leverage solar power and LED, the new green energy, as light sources for our lighting products, in order to take advantage of high technology. The main products of Solar and LED light include: LED Home Light, LED Decoration Light, LED Outdoor Light, Solar Power Light and Solar Garden Light. These products conform to CE standard of EN 61347-1:2001 and EN 61347-2-13:2006. They are popular in the global market, especially in North American and Europe. More...
