In the lamp cap, the lug boss mounting surfaces with different angles are arranged at the bottom in the heat-radiating piece for the lamp housing body, so that the LED light sources can be assembled by adopting different modes according to different functions and meet requirements for different occasions and different illumination ranges, and further the service efficiency of the LED is improved and the illumination effect of pavement is improved. The lamp cap has the advantages of electric energy saving, favorable heat radiating and illuminating effects, simple structure, and the like, and is suitable for illumination of outdoor roads.
Description
Technical field
The utility model relates to a kind of LED semiconductor lamp, especially relates to a kind of easy heat radiation, high-power LED road lamp cap.
Background technology
Traditional road-light light-source adopts high-pressure mercury lamp, high-pressure sodium lamp, 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 softly, power consumption is few, advantages such as 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 the use will directly influence the life-span of led light source, makes its lifetime.And led light source is that horizontal device is on boss, because most of led light source emission all is direct light, optically focused is good, makes LED illumination be mapped to same angle, can not fully illuminate road, 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 a kind of easy heat radiation, high-power LED road lamp cap are provided.
The purpose of this utility model is achieved through the following technical solutions:
Easily heat radiation, high-power LED road lamp cap comprise lamp housing body radiating piece, and characteristics are: the outer surface of described lamp housing body radiating piece has the polylith radiating fin, and the polylith radiating fin axially is parallel strip along lamp housing body radiating piece and arranges; Described lamp housing body radiating piece inner bottom part is provided with the boss installed surface of different angles, on the described boss installed surface aluminium base is housed, on the described aluminium base led light source is housed, is connected by printed substrate between the led light source, circular pit shape lens are equipped with in the outside of described led light source; The front end of described lamp housing body radiating piece is equipped with loam cake, on cover transparent glass be housed.
Further, above-mentioned easy heat radiation, high-power LED road lamp cap, wherein, described radiating fin is a parallel strip or circular, radiating fin group top is circular-arc distribution.
Further, above-mentioned easy heat radiation, high-power LED road lamp cap wherein, are provided with the water-proof silica-gel circle between described loam cake and the lamp housing body radiating piece.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
1. the utility model novel structure, the heat that led light source produces promptly can be conducted by the radiating 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;
2. the radiating fin on lamp housing body radiating piece becomes parallel strip vertically, and with the moulding of body withdrawing pattern, both can improve radiating effect, is convenient to make processing again; Each boss face of lamp housing body radiating piece inner bottom part has a certain degree vertically, make the illumination effect of led light source obtain maximum performance, whole lamp holder has obtained best luminous intensity distribution design, the different angles and zone that make each led light source can both shine the road surface have improved the service efficiency of led light source;
3. circular pit shape lens are equipped with in the outside of led light source, with the combination of front transparent glass, make the light efficiency of led light source higher, and are luminous soft, can eliminate the dazzling and dazzle that produces when luminous again; Connect with printed substrate between the led light source, played conserve space, reduce heat and effect attractive in appearance.
