Description

A kind of LED illuminated by surface light source light fixture

[technical field]

The utility model relates to a kind of lighting, refers in particular to a kind of LED illuminated by surface light source light fixture.

[background technology]

Existing ordinary luminaire generally all adopts fluorescent lamp or incandescent lamp bulb, and such lighting not only power consumption is big, and light is dazzling.It as the patent No. 96225173.9 bivalve body free from glare bulb, in the lamp holder outer setting two-layer housing is arranged, internal layer shell is scattered light, make it to produce soft light, but the manufacture craft of this its internal layer shell of structure bothers very much, and adopts the tungsten lamp bubble, and its power consumption is big and caloric value is high especially, the shell body of bulb is a glass, and lamp holder is easy to fragmentation.

At present, a lot of local LED of employing are arranged as lighting, but, do not meet the vision requirement, and its light is relatively dimer because existing LED encapsulation problem uses the light that LED sent to have dazzle.As the patent No. is a kind of curtain wall lamp of 200410033101.5, and the LED fluorescent tube is housed in box at the bottom of the printing opacity, and the box bottom is provided with a scattering sheet at the bottom of its printing opacity, the lamp that this method is made, though its light is very soft, very dim, can not do lighting fully and use.For another example, the patent No. is a kind of LED lighting of 200620060579.1, this patent comprises the frame of being with groove, the circuit board of band great power LED, one side is laid veined LGP, cover the reflector layer of above-mentioned LGP band texture face, cover the diffusion layer on opposite of the band texture face of above-mentioned LGP, the circuit board of above-mentioned band great power LED is arranged in the groove of frame and is positioned at above-mentioned LGP edge, wherein, between described circuit board and the described frame heat abstractor is arranged, between described heat abstractor and the described frame heat-conducting glue is arranged.This structure is sidelong LED on described frame, the light that LED sends is reflexed on the diffusion layer by reflector layer, by diffusion layer light scattering is gone out again, to reach effect of uniform light, but this lighting is because the restriction of itself structure, and the rising angle of its intensity of illumination and light all can't satisfy the lighting requirement as places such as counter, meeting platform, office, supermarkets.Therefore people suddenly need a kind of energy-saving and environmental protection, light extraction efficiency height, the high area source light fixture of brightness.

[utility model content]

At the technological deficiency that energy consumption height, dazzle, light extraction efficiency are low, brightness is low that lighting in the prior art exists, the purpose of this utility model is to provide a kind of energy-saving and environmental protection, light extraction efficiency height, the high LED illuminated by surface light source light fixture of brightness.

In order to reach above-mentioned technical purpose, the technological means that the utility model adopts is a kind of LED illuminated by surface light source light fixture, comprise lamp housing, be fixed on LED lamp plate and in the mounting groove of lamp housing bottom and be fixed on astigmatism plate on the LED lamp plate light direction, described lamp housing comprise base plate and be arranged on the base plate both sides and the base plate one first, second chamber, described first, the sidewall of second chamber and base plate form mounting groove in the central authorities of lamp housing, described LED lamp plate is fixed on the bottom of mounting groove, be fixed with power supply in described first chamber, described astigmatism plate is fixed on the sidewall of mounting groove, at described lamp housing first, the end of the opening of second chamber and mounting groove is provided with the end cap of sealing lamp housing.

Preferably, described LED lamp plate comprises that circuit board and array are arranged on the plurality of LEDs on the circuit board.

Preferably, described mounting groove is an inverted trapezoidal groove, and described LED lamp plate is fixed on the bottom of inverted trapezoidal groove.

Preferably, a pair of installing plate is stretched out in the both sides of described astigmatism plate, and the two side of described mounting groove is provided with the rail groove with the installing plate coupling, and described astigmatism plate is fixed astigmatism plate to rail groove from an end of rail groove is interspersed by the installing plate of its both sides.

Because the light of the utility model LED lamp plate directly diffuses out by astigmatism plate, it is the straight-down negative irradiation, can satisfy the required brightness of lamp lighting, can avoid the glare problem of LED simultaneously by astigmatism plate, have brightness height, perfect heat-dissipating, simple in structure, applied range, plurality of advantages such as with low cost with respect to sidelight conduction-type of the prior art system.
