A high heat dissipation led corn lamp

Abstract

The invention discloses a high heat dissipation LED corn lamp, which comprises a lamp holder, a heat sink, and an LED light source arranged on the heat sink, and is characterized in that: the heat sink includes a plurality of independent heat dissipation bars and The fixing seat, the fixing seat includes a top fixing seat at the top of the heat dissipation strip and a bottom fixing seat at the bottom of the heat dissipation strip; the heat dissipation strip is provided with a card slot for fixing the LED light board, and the LED light board is arranged in the card slot; all The cooling strips are distributed around an axis, a ventilation gap is provided between two adjacent cooling strips, a hollow ventilation channel is provided in the middle of the radiator, and the ventilation channel communicates with the ventilation gap. Preferably, the heat dissipation strip is a strip-shaped hollow enclosure; the part of the heat dissipation strip located on the back of the slot is provided with at least one cut through the heat dissipation strip; an annular vent is formed between the lamp head and the radiator top fixing seat ; A top annular LED light source assembly is provided around the edge of the top surface of the radiator. The invention has the advantages of good heat dissipation performance and large luminous angle.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an LED corn lamp with high heat dissipation performance and large light-emitting angle. Background technique [0002] LED corn lamp is a kind of LED lamp, which belongs to the light source category. It emits light around 360 degrees. Its shape and lamp bead distribution are like corn cobs, so it is called LED corn lamp. Due to the high brightness, large luminous angle and good heat dissipation effect of LED corn lights, they are more and more widely used in various lighting occasions. [0003] A kind of basic structure of existing LED corn lamp can refer to the patent that publication number is CN205579217U, and its structure is: comprise lamp base, the radiator that is connected with lamp base, the LED light source that is arranged on radiator; The structure of its radiator is: A hollow cylindrical body and a plurality of uniformly distributed heat dissipation plates extending from the ...

AI Technical Summary

Problems solved by technology

At this time, the height of the slot is generally set slightly larger than the thickness of the circuit board of the straight LED light board, otherwise the straight LED light board is difficult to insert into the slot; but the height of the slot is greater than the thickness of the circuit board, which will make the circuit The board cannot be close to the heat sink, which affects the heat conduction of the straight LED light board

That is, the setting of the cooling plate of the existing LED corn lamp cannot meet the requirements of convenient installation and good heat conduction at the same time
