Lighting with LED also need to "water-cooled" showcase installation module

White light-emitting diode (LED) light emitting efficiency is more high. A few years ago, only about 20lm/W, and now there are already a lot of up to 40 ~ 50lm/W.

The deepest impression is the lighting appliance manufacturers. "LED from the decoration to the lighting source has been just around the corner!" In the "Lighting Exhibition 2005" (March 1, 2005 - 4) on the company to display photos by LED appliance.

One of the areas that the company is currently trying to address is the use of LED in lighting fixtures". Although the luminous efficiency is getting higher and higher, but the heat of the LED chip is still very large. If you do not take the cooling strategy, the temperature of the LED chip will be too high, leading to the deterioration of the chip itself and the packaging resin performance, which eventually led to the reduction of luminous efficiency and shorten the life. LED is one of the most important performance indicators is "long life", in order not to affect the index, you need to try to heat the chip out.

Install cooling module in the showcase

In order to solve the heat problem, Koizumi industry in the showcase installed a water-cooled LED module. The company's jewelry retail counters in the use of LED lighting and a reference display. Glass counters on the upper side of the LED lined up, behind the white part of the water cycle through the cold. Through the water cooling mode to the LED module, so that customers often touch the glass cabinet will not be too hot. Compared with the fluorescent lamp, LED radiation of ultraviolet light, while compared with incandescent light, thermal radiation is also smaller. Therefore, LED is suitable for jewelry and cosmetics counters lighting.

Another kind of heat dissipation design is also very interesting: the heat sink is not only used for the purpose of heat dissipation, but also has the function of improving the beauty of the lighting device. This is the Panasonic Industry Exhibition desktop support. The teeth on the heat radiating fins are arranged in the shape of a human figure, and the LED module used as the light source is installed with a lampshade. At the same time, other manufacturers of LED lighting display, but also the use of metal materials, while taking into account the beauty and heat dissipation.
