Description
Technical field
The utility model relates to field of light fittings, particularly a kind of LED Projecting Lamp.
Background technology
LED has advantages such as environmental protection, energy-conservation, life-span be long and is regarded as the lighting source of tool potentiality of 21 century, and the LED Projecting Lamp is formed lighting source by LED, is mainly used in building decoration illumination, road lighting, billboard lighting etc.
Though it is cold light source that LED belongs to, when work, still can produce heat, serious decay appears in the brightness meeting at high temperature of LED Projecting Lamp.Scatter if heat is untimely, often temperature raises rapidly in the short time, causes brightness to decay fast, has a strong impact on the LED life-span.LED Projecting Lamp of the prior art on the one hand, only is provided with fin behind led light source, its radiating effect is undesirable; And LED is short in bad following life-span of background of heat radiation, needs often more change the bulb, and when outward appearance or billboard more change the bulb, the shortcomings such as potential safety hazard of falling is arranged in the building; On the other hand, the shell of LED Projecting Lamp is made up of a plurality of parts, the fin independent installation; Therefore, the manufacturing of this LED Projecting Lamp is comparatively complicated, assembles also very loaded down with trivial details.
The utility model content
The technical problem that the utility model will solve is the deficiency to above-mentioned prior art, provide that a kind of manufacturings is simple, assembling easily, and radiating effect well, longer LED Projecting Lamp of life-span.
The technical scheme of the utility model is: a kind of LED Projecting Lamp, and comprise housing, and be arranged on led light source, circuit board and power supply unit in the housing, after being electrically connected, power supply unit and circuit board be opposite to the led light source power supply of circuit board one side; Said housing comprises fore shell and the back cover that links together; Fore shell one end is a groove shape structure, and circuit board and led light source place the bottom of this groove shape structure; The back side of fore shell and the circuit board joint place fin of deriving, this fin and fore shell are one-body molded, and extend to back cover is inner; The fan that is electrically connected with power supply unit is set in the back cover, and this fan is near the end of fin, and back cover is divided into a ccontaining fin section and a ccontaining power supply unit part; The back cover side of ccontaining fin section sets out pore, and the back cover side of ccontaining power supply unit part is provided with air admission hole.
Preferred version as the utility model; The inwall of said back cover is derived to back cover inside has the spacer with passage; This spacer is near the end of fin; Said fan is installed on the spacer, and spacer and fan are divided into a ccontaining fin section and a ccontaining power supply unit part with back cover together.
The set inside of groove shape structure one end of said fore shell has reflector, and the reflector front is provided with diffuser.
The beneficial effect of the utility model is: the housing of LED Projecting Lamp comprises fore shell and back cover, and fore shell and fin are an overall structure, and back cover also is an overall structure, so LED Projecting Lamp operation when making and assemble is simple, assembling is easy; The fore shell of LED Projecting Lamp is provided with fin; Back cover is provided with fan, venthole and air admission hole; Air gets into from air admission hole and passes to fin through fan, by fin led light source is dispelled the heat again, and the hot gas of dispersing at last flows out from venthole; Therefore the radiating effect of LED Projecting Lamp is very good, and the life-span of led light source is greatly improved.
