The led light source street lampTechnical field
The utility model relates to a kind of street lamp, relates in particular to a kind of high-power LED light source street lamp that is applicable to.
Background technology
Light emitting diode (LED) has good illumination effect and low power consumption and other advantages, has been widely applied to lighting field, such as illuminating lamp for plant and street lamp etc.
But LED has its geneogenous defective as light source, namely at high temperature burns easily, has a strong impact on the LED life-span, so for LED, heat radiation is an important link.As street lighting, LED need to provide longer illumination length simultaneously.
Summary of the invention
In order to overcome defects, the utility model provides a kind of led light source street lamp, and this light source road lamp is simple in structure, and good heat dissipation effect has longer illumination length.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of led light source street lamp, comprise housing, some groups of LED lamp unit, reflector and Transparent lamp shades, described every group of LED lamp unit is comprised of led light source, double-side convex lens component, half-cylindrical curved lenses and lens carrier, described led light source is adhered on the described housing medial surface, has several fins of one extrusion modling on the described hull outside face as radiator; Described double-side convex lens component and half-cylindrical curved lenses are fixedly arranged in the described lens carrier over against described led light source setting and this double-side convex lens component and half-cylindrical curved lenses successively, this lens carrier is fixedly arranged on the described housing medial surface, and the opening part that described reflector and Transparent lamp shade are covered in described housing successively forms closed structure.
As further improvement of the utility model, the surperficial undulate of described fin.
As further improvement of the utility model, described fin near the density at described led light source place greater than the density away from described led light source place.
As further improvement of the utility model, being centered close on the same straight line of described led light source, double-side convex lens component and half-cylindrical curved lenses, and this double-side convex lens component is all vertical with the light that send at described led light source center with half-cylindrical curved lenses.
The beneficial effects of the utility model are: by the time street lamp casing outer surface straight forming form radiator, not only be beneficial to heat radiation, improve radiating effect, and simplified structure, reduce production costs, adopt simultaneously the disperse function of two lens, improve illumination length, make street lamp cover as much as possible distance between two street lamps.
Description of drawings
Fig. 1 is the utility model structural representation.
By reference to the accompanying drawings, make the following instructions:
1---housing 2---reflector
3---lampshade 4---led light source

7---lens carrier 8---fin
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, and the simple equivalence of namely in every case being done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
A kind of led light source street lamp, comprise housing 1, some groups of LED lamp unit, reflector 2 and Transparent lamp shades 3, described every group of LED lamp unit is comprised of ledlight source 4, double-side convex lens component 5, half-cylindrical curved lenses 6 andlens carrier 7, described led light source is adhered on the described housing medial surface, has several fins 8 of one extrusion modling on the described hull outside face as radiator; Described double-side convex lens component and half-cylindrical curved lenses are fixedly arranged in the described lens carrier over against described led light source setting and this double-side convex lens component and half-cylindrical curved lenses successively, this lens carrier is fixedly arranged on the described housing medial surface, and the opening part that described reflector and Transparent lamp shade are covered in described housing successively forms closed structure.Like this, directly form radiator by housing, not only simplified structure reduces cost and installation steps, improves simultaneously radiating effect; In addition, adopt two lens to improve and disperse effect, increase illumination length, can make street lamp shine as much as possible the direct distance of two street lamps.
Preferably, the surperficial undulate of described fin.
Preferably, described fin near the density at described led light source place greater than the density away from described led light source place.
Preferably, being centered close on the same straight line of described led light source, double-side convex lens component and half-cylindrical curved lenses, and this double-side convex lens component is all vertical with the light that send at described led light source center with half-cylindrical curved lenses.
