LED radiator structure

Technical field

The utility model relates to field of LED illumination, particularly a kind of LED radiator structure.

Background technology

Existing LED lamp application is more and more extensive, considers to the hyperthermia and superheating phenomenon produced during LED operation, needs the object reaching auxiliary heat dissipation in conjunction with radiator.LED light source operationally, a large amount of heats can be given out, power is larger, and the heat distributed is more, according to all making of plastic material, its thermal conductivity factor is little, heat transfer is slow, have influence on speed and the efficiency of heat propagation, the temperature of radiating shell itself is raised, also directly has influence on the normal work of LED, cause LED temperature too high, very easily lost efficacy or affected the use safety of light fixture.

Utility model content

In view of this, the LED radiator structure providing a kind of radiating efficiency high is necessary.

The technical solution adopted in the utility model is: a kind of LED radiator structure, comprise bulb housing, shell of lamp base and substrate hot linked with LED light source, this bulb housing covers on this shell of lamp base and forms cavity with the top of this shell of lamp base to accommodate this substrate, this bulb housing is provided with the first passage, this shell of lamp base is provided with the second passage, the top of this shell of lamp base is provided with ventilation post, this ventilation post is positioned at this cavity, the middle part of this ventilation post is provided with the gas channel of up/down perforation, the gas channel of this ventilation post is communicated with this first passage and this second passage, the part of this substrate to be connected on this ventilation post and at least part of gas channel stretching into described ventilation post of this substrate.

Compared with prior art, this LED radiator structure by arranging this first passage 11, arranging this ventilation post and this second passage on this shell of lamp base on this bulb housing, heat loss through convection passage is formed to make this first passage, this ventilation post and this second passage, and by the gas channel stretching into this ventilation post at least partly of these substrates, the heat making these substrates produce like this can be dispersed into space outerpace timely by heat loss through convection passage, substantially increase the radiating efficiency of LED, add the service life of LED.

Detailed description of the invention

Fig. 1 is the three-dimensional exploded view of the LED radiator structure of the utility model first embodiment, this LED radiator structure comprises bulb housing 10, shell of lamp base 20 and substrate 30 hot linked with LED light source 40, and this bulb housing 10 covers on this shell of lamp base 20 and forms cavity with the top of this shell of lamp base 20 to accommodate this substrate 30.

Please refer to Fig. 1 and Fig. 2, this bulb housing 10 is provided with the first passage 11, and these the first passages 11 are arranged at the top of this bulb housing 10.This bulb housing 10 was hemisphere bubble shell structure, and this bulb housing 10 is fastened by two and half housings and forms.

Please refer to Fig. 1 to Fig. 3, the top of this shell of lamp base 20 is provided with ventilation post 21, and this ventilation post 21 is one-body molded with this shell of lamp base 20.This ventilation post 21 is positioned at this cavity, and this ventilation post 21 is arranged on the axis of this bulb housing 10.The middle part of this ventilation post 21 is provided with the gas channel 211 of up/down perforation, and this shell of lamp base 20 is provided with the second passage 22, and the gas channel 211 of this ventilation post 21 is communicated with this first passage 11 and this second passage 22.In the present embodiment, power supply cavity 23 is provided with in this shell of lamp base 20, these second passages 22 are communicated with this power supply cavity 23, the gas channel 211 of this ventilation post 21 is communicated with this second passage 22 by this power supply cavity 23, and namely this first passage 11, this gas channel 211 form a heat loss through convection passage with this second passage 22 like this.The bottom of this bulb housing 10 is provided with the 3rd passage 13, these the 3rd passages 13 communicate with these second passages 22, this the second passage 22 can be entered to make outside air, when the second passage 22 of this bulb housing 10 this shell of lamp base 20 completely not coated, the 3rd passage 13 also can not be set.

Please refer to Fig. 1 to Fig. 3, the part of this substrate 30 to be connected on this ventilation post 21 and at least part of gas channel 211 stretching into this ventilation post 21 of this substrate 30, to make air in heat loss through convection passage through this substrate 30.These LED light sources 40 are arranged at these substrates 30 and are positioned at part outside this gas channel 211.The sidewall of this ventilation post 21 has mounting groove 212, this substrate 30 is fixed on this mounting groove 212.In the present embodiment, this LED radiator structure comprises at least two substrates 30, and these substrates 30 are planar structure, and one of them substrate 30 has slot to make way 31, and these substrates 30 are mutually arranged in a crossed manner and in these mounting grooves 212 of corresponding insertion by this slot to make way 31.Preferably, these substrates 30 are arranged through the axis of this bulb housing 10.
