LED lighting cooling components are more competitive
1 Low-power LED lighting and cooling components industry competition
Low-power LED lighting products have low power consumption and low heat generation, which mainly depends on the heat dissipation of the lamp housing. There are a large number of lighting or hardware processing enterprises engaged in the processing of small-power LED lighting products, and the production is relatively scattered, and the number of enterprises with large-scale supply capacity is small. The rapid increase in the market penetration rate of low-power LED lighting products has also attracted a large number of home-based companies to infiltrate into the field of low-power LED lighting, which has intensified competition in this industry. At present, most enterprises in the low-power LED lighting and heat-dissipating component industry are not high in technology and relatively backward in manufacturing process, and they do not pay much attention to the heat dissipation design of lamps. The quality of products is not high. Such enterprises are mainly involved in the competition of low-end products.
2 High-power LED lighting and cooling components industry competition
High-power LED lighting products are rich in specifications and specifications, mainly as energy-saving alternatives to traditional metal halide lamps, high-pressure sodium lamps and other lighting sources, and are currently in the market introduction period.
The power of a single-chip LED light source on the market is usually around 1-5W, and the light output is only a few hundred lumens. The LED is really used in public places such as road lighting. The luminous flux of the LED light source must reach several thousand or even tens of thousands of lumens. The amount of light output cannot be achieved with a single chip, so in LED lighting applications, two main types of lamps have been formed to meet the corresponding illumination brightness requirements. One is an array type LED lamp, which adopts a combination matrix structure lamp design concept, and arranges a plurality of single-chip LED light sources in a matrix form to form a large light-emitting panel; the other is an integrated LED lamp, which mainly adopts multiple A chip-integrated LED light source that closely mounts multiple LED chips on the same metal substrate to meet the lighting needs of public places.
The structure of the two types of LED luminaires differs depending on the arrangement of the LED chips, and the lighting curve, space and heat dissipation requirements are different. Array LED lamps have large illumination areas and are limited in application. They are currently used in lighting fields such as street lamps and tunnel lights. Because the technical requirements for heat dissipation are relatively low, the technical implementation scheme is relatively simple. Some large-scale LED lighting manufacturers and professional LED lighting and heat-dissipating component manufacturers have technical strength and fierce competition.
