NTEC Co., Ltd. (Head Office: Yamato-shi, Kanagawa-ken; President: Junji Sotani; 100% subsidiary of Furukawa Electric Co., Ltd.; hereinafter “NTEC”), has developed a small and lightweight milan米兰体育官网入口 radiator called the Stand Kicker, offering high-power LED. Use of this product will facilitate cooling of large-sized lighting equipment and projectors using high-luminance-power LED installed in high locations.
Background
With expectations growing for LED as a trump card for energy conservation, its applications are growing increasingly broad each day. Use is expected to grow in commercial applications that require high luminance, milan米兰体育官网入口 large-sized lighting equipment and UV exposure devices. LED is a solid-state device that emits light when electrons recombine with the electron holes, but 80% of the power consumed is lost as heat. Heat loss is dissipated from the device itself but the device is characteristically extremely weak against heat. The luminance efficiency of LED decreases with the rise in LED temperature. Related components, such as packages, also deteriorate with heat and their luminance will decrease and life will shorten; therefore heat dissipation is a vital factor.
In household LED lighting, generated heat is a few watts, and simple measures such as die-cast fins are sufficient. However, to replace high ceiling lighting with LED lighting, milan米兰体育官网入口 factories, gymnasiums, auditoriums or stages, the generated heat from the surface of the LED light, with an equivalent illumination intensity of a 600W class mercury lamp, for example, will be around 150W. And in outdoor lighting (stadiums, airports, highways, etc.) where 1kW class mercury lamps are used, there will be more than 300W of heat generated.
Since this lighting is frequently used in high locations, it had been difficult to use conventional extruded materials or die-cast fins to dissipate heat, since the radiator is too large and heavy for commercial use. It was essential to develop milan米兰体育官网入口 and lightweight radiator with high performance under a new concept that would efficiently dissipate heat without fans, to realize lighting devices with long life and high reliability for the abovementioned uses.
Product details
milan米兰体育官网入口 LED lighting
By combining a thermally superconductive “milan米兰体育官网入口”(note 1)with longitudinal fins suited for natural convection cooling, NTEC has developed the lightweight (50% lighter than solid heat sink) and small (30% smaller than solid heat sink) milan米兰体育官网入口 high-performance radiator that enables cooling by natural convection.
The milan米兰体育官网入口s are arranged on the heat receiving base plate for mounting the LED device that extends at almost a right angle with some space between the multiple aluminum heat dissipating fins placed longitudinally in the direction of the milan米兰体育官网入口s. By effectively joining the longitudinal fins with the milan米兰体育官网入口 thermally, a small, lightweight natural system of convection cooling has been achieved. Related patents have already been applied for.
The newly developed milan米兰体育官网入口 comes in various shapes to accommodate LED heat generation of 100-1,000W.
NTEC will design, prototype and commercially manufacture various milan米兰体育官网入口s that meet the requirements of customers.

This is also called a thermal superconductor. It is a heat transfer device using the phase transition of fluid sealed under a vacuum within a container, and is used to cool and dissipate heat in space rockets, communications equipment and mobile equipment (laptop computers, game consoles, etc.).Back to Main Conten
