The new technology of the multi chip package fuyitone compact LED

"The current LED thermal module integrated package type on the market can only do 80 degrees Celsius, and we can put the cooling module temperature dropped to 40 degrees, can greatly improve the luminous efficiency of LED and prolong the service life of high power LED, is a revolutionary influence. "Fuyitone general manager Cai Zhou told us excitedly.

Recently fuyitong Precision Technology Co. Ltd. successfully developed a new type LED lamp radiating module, that can successfully make the LED stent temperature dropped to 40 degrees below.

New heat dissipation solution greatly improve the life of LED

At present, the main methods of LED street lamps are: natural convection heat dissipation, fan forced cooling, heat pipe and loop heat pipe cooling, etc.. But they have a lot of deficiencies, the fan cooling system is complex, low reliability, the life of the fan is often shorter than the chip, the industry has long been abandoned. Heat pipe heat sink was accepted by the industry, but the effect is far fetched. There is also a heat sink cooling, but due to limited surface area, the effect is still unsatisfactory.

"Our new products can perfectly solve the problems of traditional heat dissipation methods. This new product is our independent research and development, has a number of patent applications currently on the market, you definitely do not see similar products, the next few months, this product will be officially on the market, may cause a sensation. Cai said confidently. A news editor in 09 years in the exhibition tour, a large company said their cooling module can be 56 degrees below, is the domestic top, but is a small power LED combined, compared, fuyitone companies can be integrated package LED to below 40, the visible technology very broad prospects.

Fuyitone LED road lamp cooling solutions, the scheme not only has excellent performance, but also very exquisite in design. The heat dissipation module profile fuyitone

Features of the solution:

1, the radiating heat to the heating body to guide the central axis to the starting point on and around the whole distributed structure is called radioactive sun flower cylindrical structure, to maximize the surface area, is conducive to heat to the air diffusion.

2, the radiator with high heat Aluminum Alloy tailor-made materials, aluminum and other heat is relatively good performance of the metal surface treatment, fuyitone by special, they almost no corrosion, infinite life.

3, the innovative solutions to join the special medium in the radiator center, using a physical principle quickly spread throughout the shell surface heat radiator, and then by the high heat dissipation fin material and air exchange takes heat. This structure can be used to increase the length of the radiator to control the temperature of the LED, making the temperature of LED close to room temperature 30 degrees.

The attenuation of the life and the relationship between the three node temperature map, can be seen from the figure, the junction temperature is lower, attenuation and life performance better, red spots in the map is now the general high-power integrated package LED, yellow for a plurality of small power decentralized LED, green point fuyitone high-power integrated package type LED lamp, this solution can reach 40 degrees, the theory on life can reach 500 thousand hours.

"This new cooling structure can really do to light life more than ten years, by increasing the length of the radiator, projection lamp, this scheme can be used in more than 1000 Watt searchlight, we are developing 400W, 600W, 800W, 1200W above the projection lamp, searchlight, light in September exhibition will meet with you." Cai Zhou added. It is reported that this solution not only can be used in LED lamp, can also be used in other large power LED lamps, such as stadium, airport, wharf, bridge lights, golf course lights, RGB stage lights, RGB landscape projection lamp, square lamp, searchlights and other military, they all need a good heat dissipation performance.

Optimistic about high-power integrated packaging LED street lamp

There are mainly two kinds of street lamps in the current market: multiple small power LED combined street lamp and high power integrated package type LED street lamp. Multiple small power LED combined street lamp easy to solve the heat dissipation, single chip packaging high lumen value. But the visual effect is poor, the stars, the road shadow overlap, easy to cause the driver's visual fatigue or blurred vision, and the lighting circuit system complex lamp circuit port more, reduce the reliability; circuit is not easy to achieve dimming, easy to damage, the power conversion rate of about 85%.

High power integrated packaged LED street lamp visual effect is good, there is a reflective cup to block, avoid eyes glare, but the high requirements for heat dissipation, multiple chip integrated packaging lumens value is relatively low. In light color and lighting quality, integrated package type LED light source shows unique advantages: color uneven phenomenon will appear with a light emitting light source, uniform irradiation in the plane thoroughly, with good visual comfort, no ghosting problems combined with lights, drive a single port driver, less reliability, line arrangement of electromagnetic interference in the source does not appear; can realize the stepless dimming function; power conversion rate is about 95% higher etc.

Although the latter has better visual effect, but due to the heat problem, to the ground as the representative of the domestic mainstream LED lamp manufacturers have to choose multiple small power LED lights, LED lights do integrated packaging at home and abroad, only a handful of.

The integration of heat treatment scheme of integrated package type LED module and fuyitone, form
