Description

A kind of LED lighting

Technical field

The utility model relates to a kind of illuminating lamp, especially a kind of LED lighting.

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.Also have a lot of local LED of employing as lighting, but, do not meet current people's vision requirement, and its light is relatively dimer, is mostly only using as ornament lamp because existing LED encapsulation problem makes the light that LED sent have dazzle.For example the patent No. is 96225173.9 bivalve body No glare bulb, at the two-layer housing of lamp holder outer setting, internal layer shell is scattered light, make it to produce sheen, but the manufacture craft of this its internal layer shell of structure bothers very much, and adopts the filament incandescent lamp bulb, and power consumption is big and heating is high, its shell body is a vitreum, and lamp holder is easy to damage; The patent No. is a kind of curtain wall lamp of 200410033101.5 for another example, and the LED fluorescent tube is housed in box at the bottom of the printing opacity, and a scattering sheet is established in the box bottom at the bottom of its printing opacity, and the lamp that this method is made is very dim though its light is very soft, can not do lighting fully.In a word, the existing scheme that adopts LED as illuminating lamp, light is bright but has dazzle; There is not the effect that does not have illumination again of dazzle.

Summary of the invention

The purpose of this utility model is in order to solve the problem of above-mentioned proposition, to provide a kind of light soft free from glare, and the very bright LED lighting of light.

To achieve these goals, the technical solution adopted in the utility model is: a kind of LED lighting, comprise 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, it is characterized in that: 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, the power of described great power LED is not less than 1W, the texture of laying on the described LGP is the silk-screen texture, frosted texture or concavo-convex texture adopt cramp to connect between the described frame, described heat abstractor is aluminium base or conductor refrigeration sheet.

The utility model compared with prior art its beneficial effect has: because the utility model adopts diffusion layer, LGP, reflector layer to match with great power LED, structure and manufacture craft are all fairly simple, the light that great power LED sends is through the refraction and the reflection of LGP, and penetrate from diffusion layer through LGP after the reflection of reflector layer, light is evenly soft, free from glare is not dazzling; Illuminator adopts great power LED, and light is bright, can be used as lighting and use, and incandescent lamp and its power consumption of fluorescent lamp is smaller relatively; Great power LED is installed in the hard shell, in frame, there are aluminium base and heat-conducting glue to give great power LED and circuit board heat radiation, and the peripheral indention of frame has strengthened area of dissipation, solved the big problem of the high heating of LED power, make the working time of the present utility model very long, and can the too high damage light fixture of Yin Wendu; Adopt cramp to connect between the frame, do not have the screw screw, make the connection one integrated mass between the frame, profile is more attractive in appearance.Profile of the present utility model is very attractive in appearance, also can play the effect of ornament, is a kind of very both artistic and practical decorating lighting lamp.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2 and Fig. 3, one side at LGP 3 is laid texture, in Fig. 7,31,32,33 be respectively the LGP of being with silk-screen texture, frosted texture, concavo-convex texture, band texture face at LGP 3 covers one deck reflector layer 4, the texture face of not being with at LGP 4 covers one deck diffusion layer 2 then, and the circuit board 5 that will have great power LED 6 is placed on the edge of LGP 3; Coat heat-conducting glue 7 in the one side of aluminium base 8, again the aluminium base 8 that coats heat-conducting glue 7 is inserted in the groove of frame 1, after frame 1 put circuit board 5, be enclosed within again on diffusion layer 2, LGP 3 and the reflector layer 4, circuit board is in the groove of frame 1, do not paste mutually with aluminium base 8, and diffusion layer 2, LGP 3 and reflector layer 4 are clamped by frame 1 with the one side of heat-conducting glue 7; 1 on circuit board 5 and frame also have two shell fragments 9, and the assembly in the frame 1 can not slided in groove; Again cramp 10 is placed in the draw-in groove of frame 1, another frame 1 is placed on the cramp 10, cramp 10 is placed in the draw-in groove corresponding with it on this frame 1, and other two frames 1 are also used the same method to install, and at last aluminum soleplate 11 usefulness screws 12 is installed in the bottom of frame 1.As shown in Figure 1, its structure as shown in Figure 3, Figure 4 after all installing.Circuit board 5 and great power LED 6 not only can be arranged at two opposite side edges of LGP 3, also can be arranged at two adjacent side edges of LGP, can also circuit board 5 and great power LED 6 all be set at three limits or the edge, four limits of LGP, and LGP 3 also can be arranged to other shape, such as circle, ellipse, star etc., frame 1 also can be made respective shapes.Circuit board 5 can adopt hard strip circuit plate, also can adopt the flexible bar type circuit board.

Great power LED is luminous after energising, and light sends from the surface of diffusion layer 2 after optical waveguide layer 3, reflector layer 4 and diffusion layer 2 conduction, and the soft free from glare of light is not dazzling.Owing to use great power LED, so light is very bright, can be used for throwing light on.Heat conductive insulating solid 7 can conduct to the heat that circuit board 5 sends on the frame 1 and dissipate, and frame 1 is the hard Heat Conduction Material.
