LED application manufacturer "Liquid Solid" LITMS technology won the 2008 National Invention Invention Gold Medal
High-power LED lighting currently faces many technical challenges. In order to solve the problems in this field, the LED industry has developed many different methods to solve core problems including heat dissipation, light type, brightness, service life and cost.
Taiwan's LED application manufacturer Liquidleds Lighting Corp. has developed the Liquid Immersion Cooling Technology (LITMS) for high-power LED lighting and won the Gold Medal of the 2008 National Creative Invention Award. In the first half of 2008, he won the gold medal in the 11th Moscow Invention Exhibition in 2008. It can be said that it is the light of Taiwan's industry.
Heat dissipation and light type are two major problems in the LED lighting industry
The application of white LED in the lighting industry was developed in 1996 by Nichia, a Japanese LED manufacturer. In 1998, Lulumineds developed a high-power LED product LUXEON LED packaged by thermoelectric separation. It is the beginning of the LED manufacturers in Japan, Europe, the United States, Taiwan, the mainland, South Korea and other countries to enter the stage of LED lighting competition. However, the high-power LEDs thus created have illumination defects with a narrow exit angle and do not meet the requirements of the North American Institute of Lighting Engineering (IESNA). The main illumination must have a uniform and wide range of light requirements.
In addition, if the high-power LED heat dissipation problem is not handled well, it will accelerate the brightness attenuation (light decay) phenomenon, thereby reducing the brightness and service life of the product. At present, high-power LED lighting products on the market generally adopt back-type heat dissipation technology, and their product appearance and heat dissipation efficiency are not easily accepted by consumers. This is the biggest bottleneck of the LED lighting industry at present, so the current LED lighting market Commonly seen are the application of auxiliary lighting and situational lighting, and there are few main lighting products with high visibility.
Patented technology that combines heat dissipation, light decay, and light mode
The "Liquid Immersion - Thermal Management Solution (LITMS)", designed by the "Liquid Solid State Lighting" R&D team and has been patented by many countries, solves the above three problems. It no longer uses the back end commonly used by LED products. Metal heat dissipation, but the AC LED crystal grain around the metal column, let the LED heat forward, coupled with a unique patented liquid, for 360-degree omnidirectional heat dissipation, which makes full use of metal, liquid Different heat dissipation characteristics, the former is fast in heat conduction, and the latter is higher than heat. Under the mechanism of mutual matching, the AC LED-based high-power LED bulbs are well controlled and solved in the heat dissipation problem.
Jiang Kunyuan, general manager of Taiwan Liquid-Solid Solid State Lighting Co., Ltd. said: "With the forward liquid cooling design of the patented LITMS technology, the innate limitation (directivity) of the LED narrow light exit angle can be effectively solved, thereby greatly expanding the illumination angle of the LED bulb. Increasing luminous lumen efficiency, the actual light output per watt is much higher than the average LED bulb."
LITMS patented technology can be effectively combined with LED semiconductor standard process. Its unique glass vacuum packaging technology can make LED bulbs without any exposed metal fins, which can avoid the danger of electric shock and easy to pass international safety regulations. Certification.
What is Liquid Immersed Heat Management Solution?
It is a new generation of LED cooling technology that can make the high-power AC LED's light decay, heat dissipation and light type problems work. It will open a new dawn for the LED lighting industry in the 21st century.
LITMS has the following characteristics:
The patented heat dissipation of this unique high-power AC LED is no longer heat-dissipated through the Back Slide's Heat Slug, but through a metal stem surrounding the AC LED and a patented formulation liquid. For 360 degree omnidirectional cooling.
The unique 360-degree omnidirectional heat dissipation patent, with the patented LITMS technology, can avoid the adverse convection heat dissipation effect of the bulb device when it is embedded in the lamp holder, which can completely solve the heat dissipation problem of the high-power AC LED.
By using the forward liquid-cooled bubble design in the patented LITMS technology, the innate limitation of the LED narrow light exit angle can be effectively solved, thereby greatly expanding the illumination angle of the LED light bulb, so as to achieve the wide and uniform illumination necessary for the main illumination light bulb. Claim.
The transverse conduction axis is designed to distribute heat evenly in the liquid and on the surface of the glass, and then use the good heat dissipation characteristics of the glass surface to directly exchange heat with the air. In addition to the rapid diffusion of the heat flow, the reflective and astigmatic materials are also plated on the lateral conduction axis, so that the light increases the light diffusion effect on the surface, thereby increasing the light extraction efficiency.
