Abstract

The invention discloses a light-emitting diode (LED) lamp. The bottom of a radiator is batwing; LED heat radiation strips are fastened in grooves at the bottom of the radiator; one or more radiator fans are arranged in the lamp and directly radiate heat of the LED heat radiation strips which are exposed out of the radiator. Simultaneously, the bottom shapes of the radiator are set to be a plane shape, an arc-shaped polyhedron shape, a semi-circular polyhedron shape, or a hemispherical polyhedron shape according to different light distribution curves of various lamps, so that effects of the light distribution curves of the lamp are achieved. By using the LED heat radiation strips, the LED lamp is convenient to maintain; and by using a built driving heat radiation structure, the heat radiation effect is improved, so that the effective service life of the LED is guaranteed.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a built-in heat dissipation LED lamp. Background technique [0002] LED light sources have been used in high-power LED lamps due to their advantages of energy saving, environmental protection, and long life. LEDs are very directional, and most of the light is directed toward the road below the lamp, which cannot cover the dark area between the two lamps, often resulting in a "zebra crossing" phenomenon of bright and dark alternates on the road. 2. The heat dissipation effect is not good. The existing high-power LED lamps, especially street lamps, are currently the most widely used to install a large number of heat sinks on the outside of the lamp itself, and dissipate the heat generated by the LED through the natural convection between the outer surface and the air. This heat dissipation method is simple in design, but the heat dissipation efficiency is not high. At the same time, due to the exist...
