Detailed description of the invention

Below in conjunction with accompanying drawing, introduce the utility model embodiment in detail.

Consult Fig. 2 to Fig. 6, the utility model provides a kind of fixed structure of LED diffuser plate of improvement, and it comprises lamp body and diffuser plate; Lamp body 2 is cylindrical shape, by torsion spring 3, fixed support 4 is installed at the sidewall of lamp body 2 rotationally, this fixed support 4 is at least two and circumference is uniform, in the present embodiment, being provided with two, forming for installing lamp and downward opening installation cavity 21 in lamp body 2, in the present embodiment, this installation cavity is little tubaeform in large upper end, lower end, be evenly equipped with two draw-in grooves 22, and this draw-in groove 22 is through to outside lamp body 2 in the sidewall circumference of this installation cavity 21.Be provided with the hangers corresponding with this draw-in groove 22 at the sidewall of diffuser plate 1 simultaneously, hangers to be set in draw-in groove 22 and to be fixed on lamp body 2 by diffuser plate 1, in the present embodiment, at the first hangers 11 and the second hangers 12 that diffuser plate sidewall symmetry is arranged, i.e. Central Symmetry between the first hangers 11 and the second hangers, consult Fig. 6, and the length of the first hangers 11 is greater than the length of the second hangers 12; In order to improve assembly precision and efficiency, convenient location, is provided with circular orientation step in installation cavity 21, when hangers is sheathed with in draw-in groove, this diffuser plate 1 is fitted, in order to improve laminating degree with circular orientation step, circular orientation step is provided with the arc-shaped convex of annular, consults Fig. 4 and Fig. 5.The cross section of installation cavity is identical with the shape of diffuser plate, and it can be regular polygon, such as square, regular hexagon, octagon, positive 12 distortion etc., and also can be directly circular, it can be selected according to demand.

Below diffuser plate is briefly described:

The maximum feature of diffuser plate causes very large interference to light, distribution curve flux regardless of original design is how many degree, as long as light is through diffuser plate, it can make beam angle become 160 ~ 176 °, so from the side, there is a layer sensation for mist mist in the plate face of light fixture, can prove that beam angle preferably proves to 160 ~ 176 ° greatly from this point, the larger illumination of beam angle is lower, some also can produce optical filtering, the wavelength of part cannot be penetrated, cause colour cast, as carried out interference of light process again on surface (such as: frosted, give as security line), light transmittance because of the natural phenomena of geometric optics low especially, so the base material being used for making diffuser plate should select refractive index more low better, will be lower to the interference of light.

The utility model, by side opening two draw-in grooves 22 at lamp body 2, is then directly tipped in lamp body 2, to play fixation by the first hangers 11 and the second hangers 12 on diffuser plate 1.The first hangers 11 to the second hangers 12 on diffuser plate 1 is long, and consult Fig. 6, this conveniently installs.First the first hangers 11 is tipped in the draw-in groove of lamp body 2 during installation, the second hangers is pressed in the groove 22 of lamp body 2 other end by force by the elastic deformation of plastic cement.As diffuser plate 1 need be taken out, can slightly firmly eject diffuser plate 1 by instruments such as screwdrivers at the draw-in groove of lamp body, convenient and swift.

The fixed structure of the LED diffuser plate that the utility model improves, to be slotted by lamp body and diffuser plate adds hangers, save the diffusion plate support and die sinking thereof that are used for fixing diffuser plate required for prior art, greatly reduce development cost and the manufacturing cost of light fixture, and it is simple and compact for structure, assembly and disassembly are convenient and swift, suitable production in enormous quantities.
