Figure 1: Cross-sectional view of a heat pipe embedded radial heat sink.In light-emitting diodes (LEDs), 70 percent to 80 percent of the applied electrical power is converted to waste heat. If this thermal energy is not properly dissipated, the resulting high operating temperatures lead to reduced b...

The IP Rating describes the enclosure for electronic equipment according to the definition of the European Committee for Electro Technical Standardization. IP is standing for Ingress Protection, the protection of the product against environmental effects like solid objects or liquids. The IP rating ...

Whilst our appetite for consuming electricity continues to increase, so does our awareness of the need to maximise its efficiency. One area in which every commercial enterprise could not only harness energy more efficiently but ensure that the environment benefits, is through the replacement of fluo...

LED Growth Light adopts the technology of semiconductor lighting technology which is dedicated to the growth of vegetables and flowers. The wavelengths of red and blue are more suitable for the growing, blooming and bearing fruit of vegetables and flowers. The blue light is conducive to the growth o...

The relationship between LED street lamp power, lamp pole and height and road width The height of general lighting is 8 meters, the distance between street lights is generally 30 meters, and the light source can be led150w or high pressure sodium lamp 250w. First: Common LED street lamp repla...

After Edison, who monopolized the capital market, mass-produced bulbs, the application of bulbs entered an era of rapid progress. According to research data published by Fouquet and Pearson, as we develop from using handmade candles to mass-produced bulbs, the cost of artificial light Over the centu...

There are currently two basic types of solid-state lighting devices: LED, OLED. Current LEDs are very small in size (about one square millimeter) and are extremely bright. Having been developed about 25 years before OLEDs, LEDs are already employed in a variety of lighting products, such as traffic ...

What influences the lifespan of an LED Light? The longer a light source is used, the greater the economic advantage and the green footprint. Depending on the system design, minimal decrease in luminous flux over time is a normal process, the components are getting down. When this process is reall...

The Death of the Light Bulb The incandescent bulb came to life in 1880 in the workshop of Thomas Edison but it was only in 1910 that the tungsten filament lamp as we know today came into being. Since then for nearly a century the incandescent bulb has continued to be the most popular lighting de...
