Abstract
The invention discloses a turnable LED (light-emitting diode) projection lamp, which comprises a base, a left support, a right support and a rectangular lamp body, the left support and the right support are respectively rotatably mounted on both ends of the base through hollow toothed tubes, the rectangular lamp body is rotatably mounted between the left support and the right support through hollow toothed tubes, a lamp cover made of an acrylic material is mounted on a projection surface of the rectangular lamp body, a substrate for mounting LED light sources is arranged behind the lamp cover, a reflector is mounted between the substrate and the lamp cover, and a heat-conducting silica gel layer is also arranged between the reflector and the lamp cover. The turnable LED projection lamp has a simple structure, is convenient to mount and use, has the advantages of low carbon, environment friendliness and energy saving, and has larger projection surface and heat-dissipating surface, the heat dissipation effect is good, all the rotary joints adopt the hollow toothed tubes as rolling bearings, the turning is flexible, the mechanical strength is high, the stable operation of LED projection and the like is ensured, and the service life of the LED lamp is prolonged.
Description
Technical field
The present invention relates to a kind of lighting, be specially a kind of rotatable LED Projecting Lamp.
Background technology
LED has that luminous efficiency is high, power saving and life-span long advantage, and its application is more and more extensive.Existing lighting device mostly adopts LED as light-emitting component, not only good illumination effect, and economize energy, long service life.Lighting device is divided into the multiple kinds such as ceiling light, lamp affixed to the ceiling, desk lamp, floor lamp, wall lamp, shot-light, Projecting Lamp, wherein Projecting Lamp is the light fixture making the projecting environment of the illumination on appointment face to be illuminated, projecting direction can be adjusted, and possess the structure of not climate condition impact, be mainly used in ore deposit, large area operation field, contour of building, stadium, viaduct, monument, park and flower bed etc.The radiating effect of existing LED Projecting Lamp is poor, and LED light source easily damages because of overheated, and then causes service life shorter, and rotation portion is easily damaged after a long time use, affects the result of use of LED Projecting Lamp.
Summary of the invention
The object of this invention is to provide a kind of rotatable LED Projecting Lamp, poor to solve LED projector lamp radiating effect traditional in prior art, LED light source easily damages because of overheated, and then cause service life shorter, and rotation portion is easily damaged after a long time use, affect the problem of LED Projecting Lamp result of use.
For achieving the above object, the technical solution used in the present invention is:
A kind of rotatable LED Projecting Lamp, it is characterized in that: include base, left socle, right support and rectangle lamp body, described left socle and right support are rotatably installed in base two ends respectively by hollow tooth pipe, described rectangle lamp body is rotatably installed between left socle and right support by hollow tooth pipe, the one side of described rectangle lamp body is light projector face, the one side relative with light projector face is radiating surface, described light projector face is provided with the lampshade of acrylic material, described lampshade rear is provided with the substrate for installing LED light source, between described substrate and lampshade, reflector is installed, thermal conductive silicon glue-line is also provided with between described reflector and lampshade.
Described a kind of rotatable LED Projecting Lamp, is characterized in that: described radiating surface is provided with the gelled heat sink of band.
