Different cooling materials for LED lamps (1)

The commonly used cooling material for electric devices is aluminum. In some special cases, copper is also used, like CPU. Copper better than aluminum in capacity of heat-transmission but worse in capability of heat radiation. Compare two radiators with same construction but made by different materials, radiator made by aluminum are better in natural cooling. However, if cooling fans are taken into account, the result is opposite. Recently, a lot of LED manufacturers tend to introduce ceramic, c...Continue reading

Analysis for new cooling material for LED chips

Copper is the oldest cooling material for LED chips. In the beginning, LED Street Light chips are fixed on copper bases. Since copper has very good thermal conductivity, heat generated by chips can rapidly transfer into cooling devices. Even now it is still the best packaging material for chips. However, in the early stage of LED lighting, copper bases cannot be well connected with cooling devices directly. Most heat generated by LED chips gathered on copper bases, cannot be further transferred ...Continue reading

LED white light created by LED chips and fluorescent powder

There are two methods for producing LED white light: LED chips together with fluorescent powder; combination of multi-single-color LED chips. Blue-ray LED High Bay chips with fluorescent powder is the most commonly used method to generate white rays. With current fluorescent powder technique, man-made LED white rays still have big differences with natural white rays. That is the reason why white LED lamps usually have low color rendering index. Feature below shows the light spectrum...Continue reading

wired led bulb used for LED Street Lights

LED lighting is recognized as the next generation of green and low power consumption lighting technology. Single view from the luminous efficiency, LED light now has to reach and exceed the level of conventional light sources, but due to the expensive cost, they are still blocked in the popularity of LED lighting. As far as I think, wired led bulb cost problem is from the LED heat sink. Street lights, long working hours, is considered to be the first choice for LED lighting appl...Continue reading

Tasters of LED current

Why constant current is required? Lighting Emitting Diodes need to work in strict working conditions. This is determined by their properties. LED Lights are vulnerable to temperature change. LED voltage will be changed along with temperature, consequently leading to the change of LED current. As we all know, each LED has a particular working current. Long-term working in a current larger than the working current will cause damages to LEDs, even destroy them. Here constant current means LED cu...Continue reading
