High heat dissipation type LED (light-emitting diode) corn lamp

Abstract

The invention discloses a high heat dissipation type LED (light-emitting diode) corn lamp which comprises a lamp holder, a lamp holder base and a radiator, wherein the radiator is a hollow cylindrical radiator which ventilates in two ends; the side wall surface of the radiator is provided with a plurality of side light source bars; the bottom end part of the radiator is provided with an end part light source plate; and the side light source bars and the end part light source plate emit light, so that 360-degree all-around light emitting of the corn lamp is realized. A plurality of lower vent holes are formed in the end part light source plate, and a plurality of upper vent holes are formed in the lamp holder base; the upper vent holes and the lower vent holes realize up-down convection and ventilation, so that heat dissipation speed can be increased; moreover, the upper vent holes are counter bores which are beneficial for heat dissipation, and can prevent dust. A light source mounting position on the outer wall surface of the radiator is a slot design; during mounting, the side light source bars are directly inserted and mounted, so that the mounting is convenient; after the mounting, the side light source bars are fitted on the radiator, so that heat conduction effect is good. By virtue of a wiring board, the plurality of side light source bars are connected with the end part light source plate and an LED drive power supply, so that mounting and wiring are more convenient.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a high heat dissipation LED corn lamp. Background technique [0002] LED corn light is a kind of LED lamp, because the maximum light-emitting angle of LED is 120°, considering the uniform light emission, it is specially designed to emit light at 360°, and its shape is like a corn cob, so it is called LED corn light. Because the greater the power of the LED, the greater the heat generated, so the power of the LED light source of the existing LED corn lamp can only be about 6 to 8W, so that it cannot provide high-brightness lighting; if the volume of the lamp does not change If the LED power is increased, the problem of heat dissipation will be difficult. Contents of the invention [0003] The main purpose of the present invention is to provide a high heat dissipation LED corn light with 360° high-brightness illumination, which aims to improve the heat dissipation effect an...
