L E D light source module

[Technical Field]

The invention relates to a L E D light source module, in particular to an L E D light source module with good heat dissipation performance and water resistance performance.

【 n 景技术 ]

Ming tools are everywhere in our daily life. There are many lamps in the home, the community, the roads and the tunnels, especially the lamps in the roads and tunnels. The traditional lamps have incandescent lamps, high-pressure sodium lamps, metallization lamps, etc. There are many occasions for sodium lamps, but because of the high price of these lamps and the long time, #, , the power consumption is very large, and sometimes stroboscopic, gradual brightening, etc. - damage will also pollute the environment, so in recent years LED lamps are gradually replacing other lamps because of the stable illumination of LED lamps, such as stroboscopic and fade-out, low power consumption and long life. They are widely used in roads, tunnels, etc. where long-term visibility is required.

However, there is a hidden danger in current LED lamps. Because of the long-time opening of roads and tunnel lamps, and the large number, high-power power supply is required, which will cause the product temperature to be too high. In the open air or in the tunnel, LEDs are very It may be wet by rain and wet by moisture. LEDs with poor sealing are prone to burnout, which can easily cause short circuit and reduce the service life of LED lamps. In addition, traditional LED lamps generally need to be equipped with a large heat sink. The radiators of LED lamps commonly used in the market include a heat sink body with a grid-like heat sink, and an aluminum substrate mounted on the heat sink body, on the aluminum substrate. For PCBs with LEDs installed. In the above-mentioned LED luminaire, the power of the LED lamp is basically the same as the increase or decrease of the heat dissipation area of the heat sink. Therefore, if the power of the L E D luminaire is increased, a larger heat sink is required, which leads to a significant increase in cost. At present, the heat dissipation efficiency of the shaping light radiator is not very satisfactory. At the same time, in order to obtain better heat dissipation effect, the weight of the product is increased while increasing the heat sink. Since most of the lamps are used for high places, the overweight LED lamps are not only increased. The cost also increases the difficulty of installation and the risks during use, such as the risk of falling from a high altitude.

Another conventional LED light source module consists of an integral LED light source module. One LED light source module has LEDs arranged in a matrix. Such a structure is broken for the maintenance of the lamp, and needs to be replaced. entire

In the LED light source module, the LED matrix in the module is completely wasted. Dimension The cost of protection is very high.

Therefore, the modular L E D will now become the driving force for the future L E D luminaires.
