Abstract
The utility model provides a lamp cap of a high-power LED (light-emitting diode) street lamp. The lamp cap of the high-power LED street lamp comprises a lamp shell body heat dissipation part and LED light sources; a plurality of heat dissipation fins are arranged on the outer surface of the lamp shell body heat dissipation part and are arranged along the axial direction of the lamp shell body heat dissipation part in a strip shape; an LED dot matrix aluminum base plate is installed on a plane at the inner bottom of the lamp shell body heat dissipation part; the LED light sources are installed on the LED dot matrix aluminum base plate; a lens panel is installed in front of the LED light sources; and a lamp pole connecting bracket is installed at the lower end of the lamp shell body heat dissipation part. The heat generated by the LED light sources is quickly conducted out by the heat dissipation fins on the lamp shell body heat dissipation part to diffuse outside. The lamp cap solves the problem of heat transfer and heat dissipation of the LED light sources in the use, therefore, the heat accumulation can be avoided, the LED light sources cannot work for a long time at a higher temperature, and the service life of the lamp is ensured.
Description
Technical field
The utility model relates to a kind of high-power LED road lamp cap, belongs to LED semiconductor lamp technical field.
Background technology
Traditional road-light light-source adopts high-pressure mercury lamp, high-pressure sodium lamp and fluorescent lamp etc., and the shortcoming of this class light source is that the life-span is short, and heat dispersion is bad, and light is soft inadequately, and consumed power is bigger, does not meet the green illumination requirement of modern society's energy-saving and environmental protection.Along with the progress of electronic technology, utilize the lighting of High Power LED (LED) combination more and more general, have photochromic soft, advantages such as power consumption is few, long service life.But existing LED street lamp is owing to adopt the high-power LED light source, and its caloric value is bigger than general low-power LED, and long-time use will directly influence the life-span of led light source, cause lifetime.And since the emission of most of led light source all be direct light, optically focused is good, makes LED illumination be mapped to same angle, can not fully illuminate road, does not reach the needed luminous intensity distribution of road lighting by rational luminous intensity distribution design.Both influence illuminating effect, reduced the use effect of LED again.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the high-power LED road lamp cap of a kind of heat radiation and good illumination effect is provided.
The purpose of this utility model is achieved through the following technical solutions:
High-power LED road lamp cap, comprise lamp housing body radiating piece and led light source, characteristics are: described lamp housing body radiating piece appearance is provided with the polylith fin, the polylith fin axially is arranged in strips along lamp housing body radiating piece, on the plane of lamp housing body radiating piece inner bottom part LED dot matrix aluminium base is housed, on LED dot matrix aluminium base, led light source is installed, the lens panel is housed, lamp stand is housed in the lower end of lamp housing body radiating piece connects support in the place ahead of led light source.
Further, above-mentioned high-power LED road lamp cap, wherein, described fin is a parallel strip, circular or radial.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The utility model modern design, the heat that led light source produces promptly conducts by the fin on the lamp housing body radiating piece, distribute to the external world, solved led light source heat transmission and heat dissipation problem in use, thereby can not cause heat accumulation and led light source is worked under higher temperature for a long time, guarantee the service life of light fixture.The illumination effect of led light source has obtained maximum performance, and whole lamp holder has obtained best luminous intensity distribution design, and each led light source can both shine the different angles and zone on road surface, has improved the service efficiency of led light source; This light fixture has soft, the anti-dazzling equivalence fruit of light simultaneously.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: organigram of the present utility model.
The implication of each Reference numeral among the figure:
1-lamp housing body radiating piece; 2-LED dot matrix aluminium base; 3-lens panel; 4-lamp stand connects support.
The specific embodiment
As shown in Figure 1, high-power LED road lamp cap, comprise lamp housing body radiating piece 1 and led light source, lamp housing body radiating piece 1 appearance is provided with the polylith fin, fin is a parallel strip, circular or radial, the polylith fin axially is arranged in strips along lamp housing body radiating piece 1, is connected with LED dot matrix aluminium base 2 by screw on the plane of lamp housing body radiating piece 1 inner bottom part, scribbles heat-conducting silicone grease between the contact-making surface of itself and lamp housing body radiating piece 1; On LED dot matrix aluminium base 2, be printed with the conducting wire, and the welding led light source, play conserve space, reduced heat and effect attractive in appearance; In the place ahead of led light source lens panel 3 is housed, each led light source is placed in the corresponding lens pit, lens panel 3 is by screw and lamp housing body sealing and fixing, make the illumination effect of led light source obtain maximum performance, whole lamp holder has obtained best luminous intensity distribution design, each led light source can both shine the different angles and zone on road surface, has improved the service efficiency of led light source; Lamp stand is housed in the lower end of lamp housing body radiating piece 1 connects support 4, lamp stand connects support 4 and can be connected and installed on the differing heights position of lamp stand by screw as required.
Adopt said structure, the heat that led light source produces promptly can be conducted by the fin on the lamp housing body radiating piece 1, distribute to the external world, solved led light source heat transmission and heat dissipation problem in use, thereby can not cause heat accumulation and led light source is worked under higher temperature for a long time, guarantee the service life of light fixture.The illumination effect of led light source has obtained maximum performance, and whole lamp holder has obtained best luminous intensity distribution design, and each led light source can both shine the different angles and zone on road surface, has improved the service efficiency of led light source; This light fixture has soft, the anti-dazzling equivalence fruit of light simultaneously.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
