Abstract
The utility model discloses an LED down lamp capable of dissipating heat easily. The LED down lamp comprises a lens retaining ring 1, a lens 2, a down lamp shell 4, a reflection cup 5, an LED aluminum substrate 3, a heat dissipating device 6 and a fastener. A heated end of the heat dissipating device 6 extends to the down lamp shell 4, not only can be in contact with the LED aluminum substrate 3, but also can be in contact with the down lamp shell 4, so that heat of the heated end of the heat dissipating device 6 can be conducted via the LED aluminum substrate 3 and the down lamp shell 4 in a contact manner, and the heat dissipating conduction area is greatly increased; cylindrical space 9 is further formed in the center of the heat dissipating device 6, so that air convection can be realized, and a heat dissipating effect is improved; and the heat dissipating device 6 is provided with S-shaped heat dissipating fins, so that the heat dissipating area is enlarged, and the heat dissipating effect is further improved. The LED down lamp has the advantages that the temperature of each LED chip is effectively reduced during operation, and excellent effects for improving the luminous efficiency of the LED down lamp and prolonging the service life of the LED down lamp are realized.
Description
Technical field:
The utility model belongs to lighting technical field, relates to a kind of LED Down lamp that is easy to dispel the heat specifically.
Background technology:
Along with the continuous decline of chip cost and the raising gradually of LED light efficiency, with the illuminating product fast development of LED, replace the traditional lighting product gradually as light source, market prospects are wide.But the problem that LED light fixture self exists is that junction temperature of chip surpasses limit value will aggravate light decay, causes light efficiency obviously to descend, and has influence on the service life of LED Down lamp.
The radiating treatment problem has become one of vital challenge in the design work of LED Down lamp.The radiating efficiency that improves the LED Down lamp can improve the light efficiency of LED Down lamp, prolong the service life of LED Down lamp.
In recent years, people have carried out a lot of good tries aspect the heat radiation of LED Down lamp, but the structure that has is too complicated, and the radiating effect that has is not ideal enough, and we provide a kind of LED Down lamp of fairly simple heat sinking structure in this trial.
Summary of the invention:
The purpose of this utility model provides a kind of simple and can effectively to solve LED Down lamp radiating efficiency poor, causes light efficiency to descend the LED Down lamp of the heat sinking structure of the lost of life.
Above-mentioned purpose can realize by following technical scheme:
To achieve these goals, designed a kind of its composition of LED Down lamp that is easy to dispel the heat of the utility model comprises lens clasp 1, Down lamp housing 4, reflector 5, LED aluminium base 3, the heat abstractor 6 of lens 2, fixed lens and the buckle that heat abstractor 6 and Down lamp housing 4 are connected as one.
The utility model has extended to Down lamp housing 4 with the heating end of heat abstractor 6, and the heating end of LED Down lamp heat abstractor in the past is just by conducting heat with contacting of LED aluminium base, comparatively speaking, the heating end of heat abstractor 6 of the present utility model is not only by conducting heat with contacting of LED aluminium base 3, but also, increased the heat radiation conduction surface greatly by conducting heat with contacting of Down lamp housing 4; Scribble one deck heat conductive silica gel equably between the LED aluminium base 3 of the heating end of heat abstractor 6 and Down lamp and between heat abstractor 6 heating ends and the Down lamp housing 4, strengthened heat-conducting effect.
There is a column type space 9 at heat abstractor of the present utility model 6 centers, are beneficial to the generation cross-ventilation, strengthen radiating effect.
Heat abstractor 6 of the present utility model has adopted S type radiating fin, has strengthened area of dissipation, has strengthened radiating effect.
This technical scheme can produce following technique effect:
The utility model has extended to Down lamp housing 4 by the heating end with heat abstractor 6, has increased the heat radiation conduction surface greatly; Scribble one deck heat conductive silica gel equably between the LED aluminium base 3 of the heating end of heat abstractor 6 and Down lamp and between heat abstractor 6 heating ends and the Down lamp housing 4, strengthened heat-conducting effect; Also utilize the column type space 9 at heat abstractor 6 centers simultaneously, produce cross-ventilation, strengthened radiating effect; Heat abstractor 6 has adopted S type radiating fin, has strengthened area of dissipation, has strengthened radiating effect.This shows, by the enforcement of above technical scheme, make the integral heat sink effect of LED Down lamp obviously improve, the temperature when having reduced the LED chip operation has effectively played good effect to the light efficiency and the life-span of improving the LED Down lamp.
