Abstract
The utility model discloses a lamp cap of an LED street lamp and relates to an improvement of the structure of a high-power LED street lamp. The lamp cap comprises a lamp housing, a light source, a mask and a reflector, wherein the light source adopts the two LED integrated light sources; the lamp housing comprises an upper housing body and a lower housing body; the LED integrated light sources and the reflector are connected on the bottom surface of the upper housing body; supporting surfaces for the installation of the two LED integrated light sources are arranged on the bottom surface of the upper housing body; the two supporting surfaces are symmetrically distributed at the two sides of the shaft axis of the lamp cap; each supporting surface can be slanted with 1-8 degrees towards the outer side of the lamp cap; the LED integrated light sources are fixedly connected on the supporting surfaces; a cooling fin is arranged on the top surface of the upper housing body; and two reflection areas are correspondingly arranged at the arrangement positions of the reflector and the two LED integrated light sources, so that the reflector is of the bat shape. In the utility model, the lamp cap is connected with a radiator into one, therefore, the lam has simpler, reasonable and attractive structure, long service life, small size and light weight, the product tends to be miniaturized, the high-altitude using is safer, and the zebra phenomenon at the irradiated area of the street can be avoided.
Description
Technical field
The utility model relates to the improvement to a kind of high-power LED street lamp structure.
Background technology
At present, in actual applications, the high-power LED street lamp light source mostly adopts simple grain LED, LED combines by several simple grains, the lamp circuit complex structure, obviously, if do not adopt LED integrated optical source, be difficult to realize the miniaturization truly of LED high-power illumination lamp, that more can't improve the LED light fixture should have energy-saving effect and longer service life.
But adopting the existing major technique bottleneck of integrated optical source is heat radiation and luminous intensity distribution problem, a lot of light fixture manufacturers have proposed multiple solution for this reason, as the area that adopts the active heat radiation of fan, employing to enlarge the windward side strengthens thermal convection current face etc., some common problems that such scheme exists are that cost height, volume are big, and the service life of light source is short.
Summary of the invention
The utility model provides a kind of and can guarantee its service life when utilizing up-to-date LED integrated optical source at above problem, and compact conformation, can overcome the LED road lamp cap of illumination zebra phenomenon.
The technical solution of the utility model is: comprise lamp housing, light source, face shield and reflector, described light source adopts two LED integrated optical sources, described lamp housing comprises upper shell and lower house, described LED integrated optical source and reflector are connected on the bottom surface of upper shell, the bottom surface of described upper shell is provided with two LED integrated optical sources continuing surface is installed, two continuing surface symmetries are laid in the both sides of lamp holder axial line, each continuing surface is respectively towards 1-8 ° of the outside of lamp holder inclination, and described LED integrated optical source is fixedly connected on the continuing surface; The end face of described upper shell is provided with the heat radiation wing; The position that is provided with of described reflector and described two LED integrated optical sources is provided with two echo areas accordingly, makes reflector integral body be the bat shape.
The light dispersion angle of described echo area is 130-150 °.
The utility model adopts two LED integrated optical sources, has solved the complexity that adopts several LED mounting process, and has greatly reduced the light source own vol.Radiator that the utility model adopted and street lamp upper casing are integral, use the die-casting technique one-shot forming, be convenient to the installation of LED integrated optical source heat-radiating substrate, and the lamp housing bottom design become some semiellipse shape shape blades (heat radiation wing), form the special-purpose heat transfer path of a rule, increase area of dissipation, be convenient to the heat radiation of LED integrated optical source.
The utlity model has following effective effect: 1, owing to adopt LED integrated optical source, make the light source volume greatly reduce than the simple grain led light source, lamp housing and radiator fuse, and make fitting structure simpler, reasonable, attractive in appearance.2, except that the thermal resistance of LED and radiator itself, there are not other any thermal resistances, reduce the thermal resistance of heat transfer path significantly, and increased the efficiently radiates heat area greatly, greatly promoted the integral heat sink ability of light fixture, prolonged the service life of light fixture; 3, because designs simplification can reduce small product size and weight, make product more tend to miniaturization, the high-altitude is used safer; 4, reflector appropriate design, avoided the zebra phenomenon of road irradiation area; The material of LED street lamp lens is an optical glass, and transmitance 〉=93% makes in the road usable reflection zone light distribution even, has the illumination of high evenness.The utility model is particularly useful for high-power LED street lamp.
