Description
Technical field
The utility model relates to a kind of LED semiconductor lamp, especially relates to a kind of 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 type 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.The progress of electronic technology thereupon utilizes the lighting of High Power LED (LED) combination more and more general, has 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 the use with the life-span that directly influences led light source, makes its lifetime.And since the emission of most of led light source all be direct light, optically focused property 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 through rational luminous intensity distribution design.Both influence illuminating effect, reduced the use effect of LED again.
Summary of the invention
The purpose of the 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 the utility model realizes through following technical scheme:
High-power LED road lamp cap comprises the lamp housing radiating piece, and characteristics are: said lamp housing radiating piece appearance is provided with the polylith radiating fin; On the plane of lamp housing radiating piece aluminium base is installed, led light source is housed on the aluminium base, collector lens is housed in the front portion of led light source; In lamp housing radiating piece outer end lamp housing is housed; Lamp housing is provided with the knee-joint head, knee-joint head linking arm, and the end of arm is provided with rotatable anchor ear.
Further, above-mentioned high-power LED road lamp cap, wherein, said polylith radiating fin axially is parallel strip or circular distribution along the lamp housing radiating piece.
Substantive distinguishing features and obvious improvement that the utility model technical scheme is outstanding are mainly reflected in:
1. the utility model novel structure; The heat that led light source produces promptly conducts through the radiating fin on the lamp housing radiating piece; Distribute to the external world; Solved led light source heat transmission and heat dissipation problem in use, thus can not cause heat accumulation and make led light source for a long time under higher temperature work, the service life of having guaranteed light fixture;
2. a whole collector lens is equipped with in the front of led light source, can make the light fixture light extraction efficiency high, and irradiated area is big, and irradiation evenly; Rotatable anchor ear is connected with lamp stand, is convenient to install the direction of lamp holder and adjustment lamp holder;
3. this high-power LED road lamp cap has advantages such as handsome in appearance, firm in structure, saves energy, heat radiation and good illumination effect, is applicable to the illumination of outdoor road.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Fig. 1: the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, high-power LED road lamp cap comprises lamp housing radiating piece 4; Lamp housing radiating piece 4 appearances are provided with the polylith radiating fin, and the polylith radiating fin axially is parallel strip or circular distribution along lamp housing radiating piece 4, and aluminium base 3 is installed on the plane of lamp housing radiating piece 4; Led light source 2 is housed on the aluminium base 3, in the front portion of led light source 2 collector lens 1 is housed, collector lens 1 is an overall lens; Light transmittance is equipped with lamp housing 5 in lamp housing radiating piece 4 outer ends more than 90%, and lamp housing 5 is provided with knee-joint head 6; Knee-joint head 6 linking arms 7, the end of arm 7 are provided with and are used for the rotatable anchor ear 8 that is connected with lamp stand.
The said structure design can promptly conduct the heat that led light source 2 produces through the radiating fin on the lamp housing radiating piece 4; Distribute to the external world; Solved led light source heat transmission and heat dissipation problem in use; Thereby can not cause heat accumulation and make led light source work under higher temperature for a long time, the service life of having guaranteed light fixture.
A whole collector lens 1 is equipped with in the front of led light source 2, can make the light fixture light extraction efficiency high, and irradiated area is big, and irradiation evenly.
Rotatable anchor ear 8 is connected with lamp stand, is convenient to install the direction of lamp holder and adjustment lamp holder.
Advantages such as that this high-power LED road lamp cap has is handsome in appearance, firm in structure, saves energy, heat radiation and good illumination effect are applicable to the illumination of outdoor road.
What need understand is: the above only is the preferred implementation of the utility model; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
