Light emitting diode (LED) lamp

Abstract

The invention discloses a light emitting diode (LED) lamp, which comprises a lamp holder plastic part, an aluminum substrate radiator, a driver, an LED light source, and a light source lens. The plastic part is arranged at the bottom of the substrate radiator. The driver is fixed in the substrate radiator and the plastic part. The LED light source is arranged on the substrate radiator, and is electrically connected with the driver. Light beams generated by the light source after electrifying is converged and refracted through the light source lens. In the invention, the aluminum substrate radiator is a heat dissipation structure formed by an aluminum substrate and a plurality of heat dissipation fins, which reduces heat resistivity of the radiator, and simultaneously lowers the consumption of aluminum raw material due to simple structure, to really achieve effects of energy saving and environmental friendliness.

Problems solved by technology

In order to increase the heat dissipation area, the radiator is generally integrally formed with aluminum profiles. Although this structure can improve heat dissipation to a certain extent, the fins in this structure are integrally formed by aluminum extrusion. Due to the limitation of the processing technology of aluminum extrusion The surface area of ​​the fins has reached the upper limit of the technology, and it is difficult to improve the heat dissipation efficiency; in addition, because the aluminum substrate and the heat sink are combined by two independent individuals through screws, there will be a huge gap between the two due to independent combination. thermal resistance, which greatly reduces the heat dissipation effect of the radiator and affects the service life of the LED light source. In addition, due to the process of aluminum substrate and aluminum extruded radiator, the application of aluminum raw materials is high, and the production cost is expensive. The extent hinders the development of LED lighting business
