Abstract
The utility model discloses a heat radiation structure of a projection lamp, which comprises a casing, an LED chip, a heat radiation sheet and a reflecting cover, wherein the LED chip, the heat radiation sheet and the reflecting cover are arranged in the casing, the casing and the heat radiation sheet form a light source group, the casing consists of a front cover and a back cover, a fan is arranged between the heat radiation sheet and the back cover, an air inlet is arranged in a position of the tail end of the back cover right aligned with the fan part by using the use direction as the reference, and an air outlet is arranged on the side surface of the casing positioned at a connecting part of the heat radiation sheet and the back cover. The heat radiation structure has the advantages that the heat radiation effect of the projection lamp can be effectively improved, and the service life of the lamp is prolonged.
Description
Technical field
The utility model relates to a kind of projecting lamp, particularly a kind of radiator structure of projecting lamp.
Background technology
Projecting lamp is strong owing to the light degree, projection distance far is widely used in various fields, existing projecting lamp comprises housing, fin and reflection shield, fin is located in the housing, be generally the solution heat dissipation problem, just offering a through hole in housing carries out simple radiating, but this method radiating effect is poor, is not suitable for the high-power LED product.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of radiator structure of projecting lamp, and this radiator structure can effectively improve the radiating effect of projecting lamp, prolongs light fixture service life.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of radiator structure of projecting lamp, comprise housing and be located at this housing interior led chip, fin and reflection shield, described housing and fin constitute the light source group, described housing is made up of protecgulum and bonnet, between described fin and bonnet, be provided with a fan, to use direction to be benchmark, described bonnet tail end is provided with an air inlet over against the fan place, and the housing side of described fin and bonnet junction is provided with air outlet.
As further improvement of the utility model, described housing is cylindrical, and described air outlet is located at the hull outside face and is formed an annular opening.
As further improvement of the utility model, the outside is provided with several radial from inside to outside fins on the described fin, and an end of the corresponding air outlet of fin is projection laterally, and the fin of fin one end of projection stretches out in annular opening, forms several ventilation slots at interval.Fin section is exposed housing, can increase the effect of heat radiation, and several ventilation slots at interval can increase the area of heat radiation, thereby accelerate heat radiation.
As further improvement of the utility model, described fan detachably is fixedly arranged on the fin tail end.
The beneficial effects of the utility model are: this light fixture is provided with a fan stating between fin and lamp socket bonnet, the corresponding position of fan of bonnet tail end is provided with an air inlet, and the side that housing is positioned at the fan front end is provided with air outlet, strengthened the effect of ventilating, the outside is provided with some radial from inside to outside fins on the fin, one end of the corresponding air outlet of fin position is projection laterally, and the fin of fin one end of projection stretches out in annular opening, form the ventilation slot at some intervals, make fin section expose housing, increase the effect of heat radiation, increase the area of heat radiation simultaneously, thereby accelerate heat radiation.
