Problems solved by technology

[0003] Usually the bottom of the heat sink of this kind of LED lamp has a small opening, and the heat sink is put into the heat sink from the opening of the heat sink during installation, so the size of the heat sink is limited to a certain extent, and usually only smaller specifications can be used. , due to the poor heat dissipation effect of small-sized heat sinks, small-sized heat sinks are correspondingly installed with low-power LED light sources, which affects the brightness of LED lights
[0004] Moreover, LED lights on the market are usually non-adjustable in light. In order to meet various light and dark needs, LED lights with different lighting intensity are often installed in the same environment.

Abstract

The invention discloses a bright LED (Light-Emitting Diode) lamp which comprises a shell, a circuit board, an insulation sheet, a heat dissipation body, a heat-conducting fin, a copper substrate, a light guide pillar, a reflector and a transparent cover, wherein the heat dissipation body is arranged in the shell and comprises two half heat dissipation bodies which take the shape of a half bowl and are buckled together; one surface of the insulation sheet is stuck on the inner wall of the heat dissipation body, and the circuit board is arranged on the other surface of the insulation sheet; the heat-conducting fin and the copper substrate are sequentially stuck on the outer wall of the heat dissipation body, and an LED light source is arranged on the copper substrate; the light guide pillar and the reflector are sequentially covered onto the LED light source; and the transparent cover is covered outside the light guide pillar and the reflector and is installed onto the shell. As the heat dissipation body is designed into the shape of two bowls, the heat dissipation surface area can be increased, and the heat dissipation effect is enhanced. No matter how the shape of the heat dissipation body is changed and the size of an opening on the heat dissipation body is changed, the insulation sheet with the larger size can be selected according to the internal space of the heat dissipation body, the circuit board with large power can be installed on the insulation sheet, the LED light source with large power is connected, further the lighting effect is enhanced, and the service life of the bright LED lamp is prolonged.
