Abstract
The invention discloses a heat dissipation structure for a projection lamp. The heat dissipation structure comprises a case, and an LED (light emitting diode) chip, a cooling fin and a reflecting cover, which are arranged in the case, wherein the case and the cooling fin form a light source group; the case consists of a front cover and a rear cover; a fan is arranged between the cooling fin and the rear cover; an air inlet formed on the tail end of the rear cover at a position directly facing the fan in relative to the use direction as reference; and an air outlet is formed on the side surface of the case at the joint between the cooling fin and the rear cover. The heat dissipation structure can effectively improve the heat dissipation effect of the projection lamp so as to prolong service life of the lamp.
Description
Technical field
The present invention 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, has been generally the solution heat dissipation problem, and just in housing, offering a through hole 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 invention provides a kind of radiator structure of projecting lamp, this radiator structure can effectively improve the radiating effect of projecting lamp, prolongs light fixture service life.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of radiator structure of projecting lamp; Comprise housing and led chip, fin and the reflection shield be located in this housing, said housing and fin constitute light sources, and said housing is made up of protecgulum and bonnet; Between said fin and bonnet, be provided with a fan; To use direction to be benchmark, said bonnet tail end is provided with an air inlet over against the fan place, and the side of said fin and bonnet junction is provided with air outlet.
As further improvement of the present invention, said housing is cylindrical, and said air outlet is located at the hull outside face and is formed an annular opening.
As further improvement of the present invention; The outside is provided with several radial from inside to outside fins on the said fin; And an end of the corresponding air outlet of fin is protruding laterally, and the fin of protruding fin one end 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 present invention, said fan detachably is fixedly arranged on the fin tail end.
The invention has the beneficial effects as follows: this light fixture is provided with a fan stating between fin and lamp socket bonnet, and 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, and an end of the corresponding air outlet of fin position is protruding laterally; And the fin of protruding fin one end 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.
