Abstract
The utility model discloses a multi-radiating structure of a semiconductor LED illuminating lamp. The semiconductor LED illuminating lamp comprises a lamp housing, a lamp shade and a light source plate positioned in the lamp shade, wherein the lower part of the lamp housing is provided with an air inlet, and the upper part thereof is provided with an air outlet so as to form convection of airflow; and the semiconductor LED illuminating lamp also comprises radiating fins directly connected on the light source plate, and the radiating fins are arranged in the direction the same as that of the convected airflows of the air inlet and the air outlet. The semiconductor LED illuminating lamp has the multi-radiating structure, and the radiating fins are directly connected with the light source plate of the LED illuminating lamp to conduct heat; and the air fields are distributed to form convection, thus cooling the radiating fins quickly, and further avoiding heat collection and temperature rise, achieving the double radiating effect of static heat conduction and dynamic air cooling, effectively overcoming the negative effects caused by heat collection, and promoting the application and development of the LED illuminating industry.

Technical background
Semiconductor LED illumination has energy-saving and environmental protection and good electrical properties and becomes lighting source of new generation.It will substitute first generation incandescent lamp, second generation gas luminescence fluorescent lamp as the solid-state illumination light source comprehensively becomes a new generation's illumination main product.It is celebrated with higher electrical-optical conversion efficiency, and light efficiency has surpassed 100Lm/w at present.Although light efficiency is very high, electric energy is converted into heat but exist greatly, and it is bigger promptly to produce heat in the transfer process, this heat gathers and causes the reduction of LED light efficiency, the light decay aggravation has a strong impact on service life, also therefore becomes the bottleneck place of LED technical development.
At present, existing a kind ofly form the LED illuminating lamp that pneumatic convective principles solves heat dissipation problem, how further to improve radiating effect and be the present inventor and be devoted to the problem studying and solve according to the air themperature field distribution.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and makes the semiconductor LED illuminating lamp effectively solve the adverse consequences that heat gathers generation by the multiple heat dissipation structure, promotes the application and the development of LED Lighting Industry.
The technical scheme that realizes above-mentioned purpose is: the multiple heat dissipation structure of semiconductor LED illuminating lamp, described semiconductor LED illuminating lamp comprises lamp housing, lampshade, is positioned at the light source board of lampshade, the bottom of described lamp housing is provided with air inlet, top is provided with the gas outlet to form the convection current of air-flow, wherein, also comprise the fin that is directly connected on the described light source board, the direction that the convection gas that direction and air inlet and gas outlet form is set of this fin is identical.
The multiple heat dissipation structure of above-mentioned semiconductor LED illuminating lamp wherein, can comprise that also one is arranged at the drive circuit on the fin.
The beneficial effects of the utility model are: the LED illuminating lamp of multiple heat dissipation structure of the present utility model, forming pneumatic convective principles and LED heat conduction physical characteristic according to the air themperature field distribution combines, create a kind of stack radiator structure, it uses fin directly to be connected with the light source board of LED illuminating lamp, heat is conducted, can heat not gathered the quick cooling of fin again by air field distribution formation convection current simultaneously heats up, reaches static heat loss through conduction and dynamic air-cooled dual radiating effect.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the multiple heat dissipation structure of the utility model semiconductor LED illuminating lamp;
Fig. 2 is the structural representation of second embodiment of the multiple heat dissipation structure of the utility model semiconductor LED illuminating lamp.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, it is the structural representation of first embodiment of the multiple heat dissipation structure of the utility model semiconductor LED illuminating lamp, illustrate with bulb, comprise lamp housing 1, lampshade 2, be positioned at the light source board 3 of lampshade 2, the bottom of lamp housing 1 is provided with air inlet 4, top is provided with gas outlet 5 to form the convection current of air-flow, also comprise the fin 6 that is directly connected on the light source board 3, the direction that the convection gas that direction and air inlet 4 and gas outlet 5 form is set of this fin 6 is identical, also can be provided with one drive circuit 7 on fin 6.
Among this embodiment, the cross-ventilation direction is flowed into by the air inlet 4 of below, flow out from the gas outlet 5 of top, direction from bottom to top, so fin 6 vertically is provided with.
Seeing also Fig. 2, is the structural representation of second embodiment of the multiple heat dissipation structure of semiconductor LED illuminating lamp of the present utility model, and this embodiment is that example describes with the street lamp.Comprise lamp housing 1, lampshade 2, be positioned at the light source board 3 of lampshade 2, the bottom of lamp housing 1 is provided with air inlet 4, top is provided with gas outlet 5 to form the convection current of air-flow, also comprise the fin 6 that is directly connected on the light source board 3, the direction that the convection gas that direction and air inlet 4 and gas outlet 5 form is set of this fin 6 is identical.
Among this embodiment, the cross-ventilation direction is flowed into by the air inlet 4 of below, flows out from the gas outlet 5 of top, and direction is parallel to light source board 3, so fin 6 parallel being connected on the light source board 3.
In sum, direction is set must just mates with the cross-ventilation direction of fin 6 can not cause that passage blocks and influences convection current.By the structure of this multiple heat dissipation, reach static heat loss through conduction and dynamic air-cooled dual radiating effect.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
