Abstract

The invention provides a rotation type heat dissipation light emitting diode (LED) flood light which mainly solves the problems that an inductor in an existing LED flood light power supply is large in heating quantity and size, and poor in heat conduction performance and strength. The rotation type heat dissipation LED flood light comprises an LED light source, an LED power supply, a flood light shell and a flood light shade, wherein the LED power supply comprises a circuit board, a power supply box body and a power supply box cover, and the circuit board is fixedly arranged in the power supply box body. The circuit board is fixedly arranged on a base plate of the power supply box body, and the inductor is arranged on the side wall of the power supply box body. Fine wires with the diameters smaller than 0.01mm are coiled to form the inductor, and one side, far from the circuit board, of the base plate of the power supply box body is totally attached to an installation portion. The base plate of the power supply box body and the side wall of the power supply box body are integrated to form an insulation heat conduction box. By means of the rotation type heat dissipation LED flood light, the fine wires with the diameters smaller than 0.01mm are adopted, effective area is increased, the inductor size is reduced, the power supply box body is an integral piece, heat dissipation is even, and strength is high.

Description

technical field [0001] The invention relates to a rotating heat dissipation LED floodlight, which belongs to the field of LED lighting. Background technique [0002] Floodlight is a point light source that can illuminate evenly in all directions. Floodlights produce highly diffuse, non-directional light rather than clear-cut beams. Floodlights have no electrodes and rely on the principle of electromagnetic induction It emits light in combination with the principle of fluorescent discharge, so there are no necessary components that limit its life; the shadows produced are soft and transparent, and when used for object lighting, the speed of lighting attenuation is much slower than that of spotlights, and even some lighting is attenuated A very slow flood light that appears as a light source that does not cast shadows. [0003] The inductance of the existing LED power supply is generally wound with a thick wire (the wire diameter is generally greater than 1mm), which will inc...
