Description

The LED Projecting Lamp

Technical field

The utility model relates to a kind of LED Projecting Lamp, mainly is applicable to open air, body of wall facade floodlight, accent light etc.

Background technology

Along with the development of society, people are at the also energy-conservation and protection environment in consideration of making the life better with the working environment while, and the LED Projecting Lamp of Chu Xianing is exactly a good example in the market.Have following shortcoming in existing LED Projecting Lamp: existing LED Projecting Lamp lamp housing material is that plastics or sheet iron are made, and service life is shorter; And be higher than the life-span of lamp housing the service life of LED greatly, and promptly do not match the service life of lamp housing and LED, make reduce the service life of light fixture; In addition, in the prior art, generally adopt safety glass to cover on the surface, can see the components and parts of lamp housing inside from the outside, influence attractive in appearancely, in addition, because safety glass is a plane, radiating surface is little and thermal diffusivity own is bad, influences light fixture service life.

Summary of the invention

The technical problems to be solved in the utility model is: at the problem of above-mentioned existence provide that a kind of good looking appearance, thermal diffusivity are good, long service life, LED Projecting Lamp that light emission rate is good.

The technical scheme that the utility model adopted is: the LED Projecting Lamp, has lamp housing, aluminium base is installed in it, evenly arrange one group of LED particle on the aluminium base, each LED particle the place ahead all is provided with lens, two waterproof terminals are installed at the lamp housing back side, the lamp housing two ends are provided with end cap, between end cap and the lamp housing sealing ring is set, it is characterized in that: by water-proof silica-gel suitable with it aluminum loam cake is installed on the described lamp housing, last cap surface is integrated to be provided with identical bar shaped fin of one group of spacing that is parallel to each other and the through hole that matches with lens.When using, reality runs into sleety weather through regular meeting; therefore; in order to prevent that rainwater from entering lamp interior and influencing its service life; between lamp housing and two end cap, sealing ring is set; be connected by water-proof silica-gel between lamp housing and the loam cake, during installation, in the lamp housing of packing into after being welded on each components and parts on the aluminium base; smear water-proof silica-gel in the junction of lamp housing and loam cake then, both are tightly connected.Simultaneously, last cap surface is integrated be provided with one group be parallel to each other, bar shaped fin that spacing is identical, increased area of dissipation, improved the heat dispersion of light fixture.

Because of aluminum products itself have the characteristic of extinction, after illumination was penetrated in the above, energy can be decayed, thereby had reduced light intensity, for fear of this phenomenon, increased light emission rate, was coated with one deck reflective membrane at the loam cake medial surface.

The constant-current driven chip of the DC to DC that welding is electrically connected with the LED particle on the described aluminium base, the current constant of the feasible LED particle of flowing through is constant, has not only increased the stability of LED particle, but also has improved the service life of LED particle.

Described lamp housing adopts aluminium to make, and its cross section is the channel-section steel type, and it evenly is shaped on one group of bar-shaped trough that is parallel to each other on two sides up and down, increases area of dissipation, improves the thermal diffusivity of light fixture integral body, thereby prolongs the service life of light fixture.

As preferably, bond by heat-conducting glue between lamp housing and the aluminium base, the heat that the LED particle produces conducts to lamp housing by aluminium base, heat-conducting glue successively, dispels the heat better heat-radiation effect by whole light fixture.

The described lamp housing back side is rotatably connected by connector and mounting bracket, can adjust irradiating angle as required in actual the use.

Described mounting bracket end is offered arc chute, and its length is 3/4 circular arc, is fixedly coupled part with lamp housing and is provided with the slide block that matches with chute.When needs are adjusted angle, rotate lamp housing, drive the connector that is fixed on the lamp housing mountain simultaneously and rotate, make and slide in the chute of slide block on mounting bracket that its rotational angle can reach 300 degree.

Described connector is and the elastic arm of lamp housing clamping that the elastic arm other end and mounting bracket are hinged.Elder generation is hinged with elastic arm and mounting bracket during installation, utilizes the elasticity of elastic arm itself then, from both sides lamp housing is clamped fixing.

The beneficial effects of the utility model are: 1, adopt the aluminum lamp housing in the utility model, not only improved the thermal diffusivity of light fixture, and improved the service life of light fixture; 2, adopt aluminum loam cake and offer one group of strip groove that is parallel to each other thereon, form the heat radiation sheet, thereby increased area of dissipation, improved thermal diffusivity, dwindled the volume of light fixture under the identical area of dissipation simultaneously, made that light fixture integral body is smaller and more exquisite, reduced cost, the aluminum loam cake has been avoided exposing of inner components and parts than safety glass of the prior art in addition, makes light fixture more attractive in appearance; 3, the loam cake medial surface is coated with one deck reflective membrane, can effectively avoid the aluminum material extinction, has increased light emission rate.
