Many people call LEDs a cold light source. LEDs are actually heat sources because LEDs turn into a lot of electricity during operation. Poor heat dissipation can cause problems such as power supply damage, accelerated light decay, and short life. Heat dissipation is always the top priority of LEDs. LED heat dissipation is a concrete manifestation of material chemistry.
The LED light engine has occupied a 2-5% market share of advanced crystal lamps. The graphite heat-dissipating LED light engine consists of a high-power LED light source assembly, a metal heat-conducting column (referred to as "thermal-conductive column"), and an ultra-high-conductivity heat-dissipating graphite body. As an independent LED light source device, the light engine has small unit area, small volume, and free choice of multiple unit combinations. It is conveniently installed on the carrying platform with the assembly holes reserved to make lighting fixtures, which increases the freedom of design. It can be assembled freely according to the needs of use. The simple and independent LED light engine has successfully developed and produced a variety of LED applications: crystal lamps, candle lamps, bulb lamps, MR16, modular module lamps and so on.
The graphite heat-dissipating LED light engine has been fully applied to the replacement of the crystal light source. The independence of the LED light engine allows it to be removed from the luminaire without affecting other light sources, facilitating the maintenance of the luminaire and saving maintenance costs, even if one or two of the light The engine is broken, and in the case of constant power, a new light engine can be replaced in a few seconds. For the price that the customer is most concerned about, the minimum price is 4 yuan / W, the price depends on the quality of the chip, "a dozen or a watt is also there.
The traditional heat-dissipating material aluminum material has good thermal conductivity but poor heat dissipation capability. Heat conduction and heat dissipation are two concepts.
The inherent physicochemical properties of graphite make it extremely heat-dissipating. However, due to the high requirements of the preparation process, low efficiency and low cost performance, it has always become a bottleneck hindering the development of graphite heat dissipation materials. The development of graphite plastic heat-dissipating materials has superior heat dissipation performance, high production efficiency and consistency, and mass production, thus providing a high cost performance advantage. In the LED heat dissipation industry, it has the advantages of light weight, small size, fast heat dissipation and free combination.
Graphite plasticizing heat-dissipating material has high heat sinking speed and high efficiency; direct and indirect heat exchange between heat source and environment, independent heat exchange, heat deposition of heat source for reasonable transfer and exchange, and internal heat deposition temperature of heat source Control is within safe limits.
The working principle of graphite plasticized heat-dissipating material is analogous to the human body's fever. When the body temperature exceeds the normal body temperature, the pores will expand and sweat out to release the heat. The same reason is that when the heat-dissipating plastic reaches a certain temperature, it will absorb the humidity of the outer space, ensure that the active ion key is turned on, and the heat is emitted.
Faced with various plagiarism and cottage flooding in the industry, product homogeneity is serious. For the cottage products, the cottage has no future, and can only imitate its appearance, but it is not clear. "LED heat dissipation is the embodiment of material chemistry. Only a good understanding of material chemistry can make a good product.
Industry will face shuffling
With the development and improvement of LED technology, the materials suitable for LED heat dissipation are also innovating. From metal aluminum to ceramics to new composite materials (plastic aluminum), the competition in the heat dissipation material market is becoming increasingly fierce. Various heat-dissipating materials will have room for coexistence, but the market share of ceramics, plastic-clad aluminum, etc. will be compressed, because ceramic molding is difficult and fragile, and then adding a lot of energy is required; while metal materials are expensive, in LED lighting products Under the market conditions of falling prices, it seems less economical.
The popularity of LED lighting will accelerate, and by 2020 it will completely replace incandescent lamps. With the advancement of technology and the popularization of automated production, the “screwdriver†factory without technology and without core competitiveness will be eliminated in the new round of industry reshuffle.
