[Text / high-tech LED reporter Zhou Jin] The heat dissipation module and the drive module are two indispensable components in the construction of LED lamps, and are also a frequent part of structural defects.
On the basis of improving the structure and principle of traditional LED lamps, Changshu Hezhong Environmental Energy Technology Research Institute (hereinafter referred to as “Hezhong Research Instituteâ€) has developed a new generation of light source integrated body to solve the heat dissipation in the traditional lamp structure. The drive occupies a large volume, high cost and 360 degree light emission.
Sha Yongkang, director of Hezhong Research Institute, said that the development of Hezhong's new generation of light source integrated body has improved the shortcomings in the traditional design of LED lighting, and also promoted the further development of LED lighting applications to the second generation of LED lighting.
Improve heat dissipation structure
At present, all the LED chips on the market have a small single power. If the power is required, several integrations are needed to achieve the design power, which also brings the heat dissipation problem of the LED. If this problem cannot be effectively solved, the product life will be affected. . Current LED luminaires require a heat sink, resulting in increased volume and increased cost.
In addition, the so-called new type of lighting LED lamps at this stage are mostly designed with reference to the basic elements of incandescent lamps and fluorescent lamps, that is, in addition to the luminous tubes, the basic structure and principle of the original lamps are used, which makes the advantages of LED lighting insufficient. Play and at the same time lead to high costs.
Sha Yongkang said that the Hezhong Research Institute has taken into account some of the shortcomings of the current LED lighting structure. By improving the design concept of some structural components and changing the original lighting structure, the LED lamps can be improved in principle from the heat dissipation problem. "Removing the heat sink and the drive circuit reduces the size and cost. By using other technologies instead of the heat sink, the possibility of new LED lighting is realized."
Sha Yongkang said that at present, Hezhong Research Institute has produced such new types of light source integrated units in small batches, only to be widely promoted.
From the current market, although the current price of LED lamps has dropped significantly compared with the past, compared with the price of traditional lamps, the current price is still not low. With the rapid industrialization of LEDs, the future LED prices will be It will be cheaper.
40% lower cost
At present, the pattern structure of LED lamps inherits the basic styles of incandescent lamps and fluorescent lamps, which is relatively smooth for applications, but it loses the characteristics of LED itself, and it is inevitable that it is not competitive because of its shortcomings. Therefore, Sha Yongkang said that the existing luminaire construction needs to be re-innovated and innovative.
Sha Yongkang believes that if the lamp that best shows the advantages of LED is to be produced, the innovative premise is to provide DC power supply, directly supply LED lamps, reduce the driving circuit, use less electronic components, use space to dissipate heat, and the lamps can be used less or not. Device.
If a road DC system supplies power to it, electronic circuits and components are reduced, saving both cost and life. At present, converting AC power to DC power accounts for about 20% of the cost of the product. As far as the working voltage is concerned, as long as it does not affect the quality of the power supply, no pressure drop can be generated, that is, the design can meet the requirements of the lamp and the power supply.
According to Sha Yongkang, the new light source integrated body developed by Hezhong Research Institute has been applied to bulbs, fluorescent lamps and street lamps. It mainly improves the driving and heat dissipation aspects of the original structure. There are problems with LED chips that can only emit light on one side. Sha Yongkang said that they can also solve them and achieve 360-degree illumination.
While improving the original structure, the same type of product is also 30%-40% lower in cost than the original. He said that the structural changes of the new luminaires will not affect the supply of supporting structural parts of the entire industrial chain. There are very few structural parts that need to be reworked, and more than 90% of the accessories can be purchased in the existing market. This also provides convenience for the promotion of a new generation of LED lighting.
"We have developed such a new type of light source integrated body mainly to see the drawbacks of current LED lighting fixtures." Sha Yongkang hopes to use the power of industry leaders to promote the development of a new generation of LED lighting as soon as possible, through a win-win cooperation. The second-generation LED lighting alliance, on the issue of patent copyright, said that it can establish a patent pool and patent alliance by forming a unique core patent sharing method.
