As the active area of the LED chip is small and its working current is big, the operating temperature of the LED ship can increase in a short time. The rise of pn junction temperature of LED can make the optical output power decrease, accel...(more)
here are many kinds of heat sinks. In the view of manufacture, air cooled heat sinks can be divided into nano imprint lithography fins, extrusion heat sinks, casting heat sinks, folding heat sinks, improved casting heat sinks, forging heat...(more)
After Edison invented the carbon incandescent lamp in 1879, lighting technology entered a new era. Reviewing the lighting history of the twentieth Century, people found out many new light sources, such as fluorescent lamps, mercury lamps, hi...(more)
Except for being applied in the field of the refrigerator, water dispensers and other household appliances, the most important application of TEC is in the information technology field. As the cooling source of such electronic components as...(more)
In 1834, Peltier, a French physicist, found that through DC electricity one node becomes cold and the other one get hot in the closed circuit which is composed of two different metals. This effect was later named as the Peltier effect. Anot...(more)
Sorting, storing and finding a SMD (Surface Mount Device) - sometimes called SMT (Surface Mount Technology), components is not easy, this is because they are so tiny and there are so many kinds of them: different sizes, values, types, etc....(more)
The applications that need wider temperature control range, large size DUT, high power devices, fast thermal response, require higher TEC output power. Thermoelectric coolers are used for applications that require heat removal ranging from m...(more)
I am an electronics engineer, and my job includes both designing and testing. However, either designing or testing, we always use resistors and capacitors. But, usually, the values of the resistors and capacitors are not the same. We often...(more)
