"At present, the integrated packaged LED thermal module on the market can only achieve about 80 degrees Celsius, and our cooling module can reduce the temperature to below 40 degrees, which can greatly improve the luminous efficiency of LEDs and extend the life of high-power LEDs. The impact is revolutionary." Fuyitong general manager Caizhou said excitedly to us.
Recently, Fuyitong Precision Technology Co., Ltd. successfully developed a new LED street light cooling module, claiming that it can successfully reduce the temperature of the LED bracket to below 40 degrees.
New thermal solutions dramatically increase LED life
At present, the heat dissipation methods of LED street lamps mainly include: natural convection heat dissipation, installation of fan forced heat dissipation, heat pipe and loop heat pipe cooling. However, they all have many shortcomings. The fan cooling system is complicated and the reliability is low. The life of the fan is often shorter than that of the chip, and it has been abandoned by the industry. Although heat pipe heat dissipation has been accepted by the industry, the effect is far-fetched. There is also a heat sink with heat sink, but the effect is still unsatisfactory due to the limited surface area.
"Our new products can perfectly solve the problems of traditional heat dissipation methods. This new product is developed by us and has applied for a number of patents. You can never see similar products on the market. This product will be available in the next few months. Will be officially introduced to the market, may cause a sensational effect." Cai always said confidently. In the process of visiting the 2009 Guangya Exhibition, a large company said that its own cooling module can achieve below 56 degrees, which is already the top in the country, but it is a combination of multiple low-power LEDs. The company can achieve integrated packaged LEDs below 40 degrees, which shows that the technology has a very broad prospect.
The characteristics of the solution:
1. The heat dissipating structure guides the heat to be emitted upward and around the starting point of the heating element as the central axis. The whole structure is called a radioactive sunflower cylindrical structure, which maximizes the surface area and facilitates the diffusion of heat to the air.
2. The radiator adopts special high-heat-dissipation aluminum alloy material. Aluminum is a metal with relatively good heat dissipation and other properties. Fuyitong has a special treatment on the surface, and they hardly corrode and have an infinite life.
3. This solution innovatively adds a special medium to the center of the radiator, using a physical principle to rapidly spread the heat throughout the inner surface of the heat sink lamp housing, and then heat the fins and air exchange with high heat dissipation material. go. With this structure, the temperature of the LED can be controlled by increasing the length of the heat sink so that the temperature of the LED is close to 30 degrees of normal temperature.
"This new heat dissipation structure can truly achieve a light decay life of more than ten years. By increasing the length of the heat sink, the solution can be used on projector lamps and searchlights above 1000 watts. We are developing 400W, 600W, 800W, Projection lights and searchlights above 1200W will be available to you in September. "Caizhou added. It is reported that this solution can be used not only in LED street lights, but also in other super-power LED lights, such as sports tasting docks, bridge projection lights, golf course lights, RGB stage lights, RGB landscape projection lights, square lights, Military searchlights, etc., all require good heat dissipation.
Optimistic about high-power integrated packaged LED street light
There are two main types of street lamps in the current market: multiple low-power LED combination street lamps and high-power integrated package LED street lamps. Multiple low-power LED combination street lamps are easy to solve heat dissipation, and the lumen value of a single chip package is high. However, the visual effect is poor, the stars and the shadow of the road overlap, which is easy to cause the driver's visual fatigue or dazzling, and the lighting circuit system has more complicated circuit ports and lower reliability; the circuit is not easy to realize dimming, easy to damage, and the power conversion rate is low. Around 85%.
The high-power integrated packaged LED street light has good visual effect, and has the shielding of the reflective cup to avoid direct view of the strong light spot, but the heat dissipation requirement is very high, and the lumen value of the integrated chip package is relatively low at present. In terms of light color and illumination quality, the integrated packaged LED light source exhibits a unique advantage: no light color unevenness occurs in the same luminaire, and the light emitted by the light source is evenly and transparently in the illumination plane, which has a good vision. Comfort, there will be no ghosting phenomenon that plagues the combined luminaires. It is driven by a single driver, with few ports and high reliability. The circuit is arranged inside the light source without electromagnetic interference; the stepless dimming function can be conveniently realized; the power conversion rate High 95% or so
Although the latter has a good visual effect, due to the heat dissipation problem, the domestic mainstream LED street lamp manufacturers represented by Qindi have selected a number of small-power LED combination street lamps, and there are only a few domestic and foreign integrated LED street lamps.
The relationship between attenuation, lifetime and junction temperature can be seen from the figure. The lower the junction temperature, the better the attenuation and lifetime performance. The red dot in the figure is the current high-power integrated package LED. The yellow dot is a plurality of low-power distributed LEDs, and the green dot is Fuyitong high-power integrated packaged LED lamps. The solution can reach 40 degrees, and the theoretical life can reach 500,000 hours.

And also very particular about the design. Fuyitong's cooling module profile
