Description

LED light radiator structure

Technical field

The present invention relates to field of LED illumination, particularly a kind of LED light radiator structure.

Background technology

For existing LED lamp using more and more extensive, caused hyperthermia and superheating phenomenon during LED operation arrive in worry, need To achieve the purpose that auxiliary heat dissipation with reference to radiator.LED light source at work, can give out substantial amounts of heat, and power is bigger, dissipate The heat of hair is more, and according to all being made of plastic material, its thermal conductivity factor is small, heat transfer is slow, influences the speed of heat propagation Degree and efficiency so that the temperature rise of radiating shell in itself, also directly influences the normal work of LED, cause LED temperature mistake Height, easily fails or influences the safe to use of lamps and lanterns.

The content of the invention

In view of this, it is necessary to provide a kind of radiating efficiency high LED light radiator structure.

The technical solution adopted by the present invention is：A kind of LED light radiator structure, including bulb housing, shell of lamp base and and LED light The hot linked substrate in source, the bulb housing cover on the shell of lamp base and form cavity with the top of the shell of lamp base to house the base Plate, the bulb housing are equipped with the first venthole, which is equipped with the second venthole, and the top of the shell of lamp base, which is equipped with, to be led to Wind column, the ventilation column are located in the cavity, and the middle part of the ventilation column is equipped with the gas channel of up/down perforation, the air-flow of the ventilation column Passage connects first venthole and second venthole, a part for the substrate be connected on the ventilation column and the substrate at least Partial stretches into the gas channel of the ventilation column.

Compared with prior art, the LED light radiator structure by setting first venthole 11 on the bulb housing, at this The ventilation column and second venthole are set on shell of lamp base, so that first venthole, the ventilation column and second ventilation Hole forms heat loss through convection passage, and being extending at least partially into these substrates in the gas channel of the ventilation column, so that this The heat that a little substrates produce can timely be dispersed into exterior space by heat loss through convection passage, substantially increase dissipating for LED light The thermal efficiency, adds the service life of LED light.
