AI Technical Summary

Problems solved by technology

[0003] Existing LED lights have always relied on traditional aluminum fins to solve the heat dissipation problem of LEDs, which has caused an unavoidable problem. Lights that use aluminum fins for heat dissipation can only emit a light angle of less than 180 degrees. Larger luminous angle requires vertical use of light-emitting circuit boards, and it is difficult to dissipate heat. The rest of the dark area is blocked by aluminum fins, so that the spherical light reflected by the lighting lamp is strangled. This kind of bulb is used for crystal Lamps or other decorative lighting fixtures are difficult to achieve their aesthetic value. In addition, many lamps and lanterns are installed upwards, which makes a large dark area appear in the lower area that needs to be illuminated, and can only be illuminated by the reflection of the wall. Illuminated area, the practicality is greatly reduced

[0004] The heat dissipation structure of aluminum fins is a channel heat dissipation form. In order to control the junction temperature of the LED chip, the heat conduction channel from the chip to the surface of the aluminum fins must be prepared, but the combination of various materials has produced many problems. The thermal resistance of the channel makes the thermal conductivity of this channel limited. The cost of the thermal channel between these links will inevitably increase, and the effect is not very good. Some lighting lamps use the form of luminous pillars to achieve three-dimensional light. This leads to the narrowing of the heat conduction channel. In order to realize the spherical light, the volume of the heat sink is further reduced, so that although the light bulb in this light-emitting form realizes a three-dimensional light type, the junction temperature of the LED chip is very serious, and the entire lamp attenuation is very serious. Fast, contrary to the practical value of LED energy saving and long life

[0005] To sum up, the existing LED lighting lamps have the problems of low heat dissipation efficiency, small lighting angle and short service life, which need to be improved
