Abstract

The invention discloses a high heat dissipation light emitting diode (LED) lamp light source. The light source comprises an upper cover (100) made of heat-conducting insulating plastic, an LED substrate (300) with an LED lamp (200), and a driving circuit board (400) electrically connected with the LED substrate (300) and used for driving the LED substrate (300); the upper cover (100) at least comprises a rotary sleeve body (110); the driving circuit board (400) is arranged in the rotary sleeve body (110); the LED substrate (300) is fixedly connected at the lower port of the rotary sleeve body (110); and the rotary sleeve body (110) is provided with a plurality of inner and outer through air vents (111). The light source has the advantages that: the heat generated in the working process of the LED substrate can be dissipated outwards through the air vents and dissipated outwards through the heat-conducting upper cover, so that the heat dissipation effect of the light source meets the requirement; the specific gravity of the heat-conducting insulating plastic is low, and the materials are saved (due to the air vents), so the weight of the whole lamp can be greatly reduced; and because the upper cover is made of the heat-conducting insulating plastic, the processing technology is simple, the heat-conducting insulating plastic is convenient for reclamation, and the light source meets the environmentally-friendly requirement.

Description

technical field [0001] The invention relates to a high heat dissipation LED light source. Background technique [0002] The existing LED light source includes an aluminum upper cover, a driving circuit board fixed in the aluminum upper cover, a partition plate fixed on the aluminum upper cover, and a belt fixed under the partition plate. The LED substrate of the LED lamp; the aluminum upper cover is provided with two electrodes that can be electrically connected to the external power supply, and the two electrodes are isolated from each other and both are insulated from the aluminum upper cover; the two electrodes are electrically connected to the driving circuit board; the driving The circuit board is electrically connected to the LED substrate. The existing LED light source has the following disadvantages: 1. The specific gravity of metal aluminum is higher than that of plastic, which makes the weight of the existing LED light source too heavy; 2. The upper cover is made ...
