Abstract
The utility model discloses a backlight board. One end of the backlight board is provided with a clamping groove, the other end of the backlight board is provided with a projecting part, and the shape of the projecting part is matched with that of the clamping groove. By means of the ingenious use of the splicing technology of multiple backlight boards, backlight boards in any size can be spliced.
Description
Technical field
The utility model relates to a kind of backlight, particularly a kind of sliceable backlight, and the utility model also relates to a kind of lamp box that uses this backlight.
Background technology
LED lighting engineering has spread to every field at present, particularly aspect domestic lighting and commercial lighting, is getting a lot of applications the fluorescent lamp technology before progressively having replaced aspect advertising lighting.
Current advertising lamp box backlight on the market generally comprises light guidance board type and backlight board-like.
Light guidance board type, is, in LGP surrounding, light source is installed, and utilizes LGP to conduct light beam, and its shortcoming is: LGP is heavier, price; Tabula rasa formula, is at lamp box surrounding dress light source, utilizes lamp box back side reflector reflection ray to impinge upon on lamp cloth luminous, shortcoming: luminous efficiency is low.
As, Chinese patent CN200720007452.8 discloses a kind of backlight, comprises the light source that is arranged on LGP end and the reflector that is fixed on the LGP back side, and LGP is normal transparent sheet material, and reflector is closely evenly compound by colloid and the LGP back side.
And for example, Chinese patent CN02259027.7 discloses a kind of two-side light-emitting advertising back light board, an outer surface at LGP is provided with reflective sheeting, another outer surface is provided with picture, the reflection lampshade of lamp tube light source in arranging, the side of LGP is housed, LGP comprises LGP and lower LGP, reflective sheeting is arranged between LGP and lower LGP, at the outer surface of upper LGP, is provided with picture at least one, at the outer surface of lower LGP, is provided with at least one lower picture.
Disclosed backlight has complex structure, heavier, high in cost of production shortcoming equally above.
Fig. 1 shows a kind of LED-backlit plate 1, Fig. 2 shows the scheme of installation of this backlight 1, backlight 1 is on monoblock pcb board 11, to stick LED lamp bar 12 as backlight, for advertising lighting and room lighting, the shortcoming of this backlight 1 is that size is fixing conventionally, can not be arbitrarily assembled, thereby can not be applicable to the lamp box of various sizes, limit its range of application.
Utility model content
The utility model is for the deficiencies in the prior art, and a kind of simple in structure, easy to assembly, lamp box backlight that cost is low is provided.
For achieving the above object, the utility model by the following technical solutions:
A backlight, described backlight one end has draw-in groove, and the other end has protuberance, and described protuberance shape and described draw-in groove shape adapt.
Further, described backlight is provided with the groove that can embed LED lamp bar.
Preferably, described groove forms light guide structure.
Preferably, described groove is arranged in parallel.
Preferably, described groove quantity is 2.
Further, described backlight surface is provided with reflector layer.By reflector layer being set on surface, reduced product weight.
Preferably, described reflector layer is the aluminium sheet that is sprayed with white paint.
As a kind of embodiment of the present utility model, a kind of backlight is also provided, comprise some backlight assemblies, described backlight assembly one end has draw-in groove, the other end has protuberance, and described protuberance shape and described draw-in groove shape adapt, and described backlight is spliced by backlight assembly.
The utility model also provides a kind of lamp box, comprises aforesaid backlight.
The utility model also provides a kind of lamp box, and described backlight is welded on the base plate of described lamp box.
The beneficial effects of the utility model are: utilize cleverly polylith backlight splicing, can risk the backlight of any size; Easy to assembly, lightweight, cost is low.
Accompanying drawing explanation
Fig. 1 is existing backlight floor map;
Fig. 2 is the side view of backlight of the present utility model;
Fig. 3 is the assembling schematic diagram of backlight of the present utility model;
The specific embodiment
As shown in Figure 2, a kind of backlight 2 described in the utility model, its one end has protuberance 21, and the other end has draw-in groove 22, and protuberance 21 shapes and draw-in groove 22 shapes adapt.Preferably, draw-in groove 22 has elasticity.
As shown in Figure 2, backlight 2 is provided with the groove 23 that can embed LED lamp bar.Preferably, groove 23 is arranged in parallel.2 grooves have been shown in Fig. 3, but groove 23 quantity do not limit, can as required, be set to other quantity yet.
As shown in Figure 2, groove 23 can form light guide structure, and the light sending for the LED lamp bar to wherein carries out leaded light.
As shown in Figure 2, further, backlight 2 surfaces are provided with reflector layer 24.Preferably, reflector layer 21 is for being sprayed with the aluminium sheet of white paint.
As shown in Figure 3, disclose another kind of backlight 3 and comprised the first backlight assembly 31 and the second backlight assembly 32, first backlight assembly 31 one end have the first draw-in groove 312, the other end has the first protuberance 311, second backlight assembly 32 one end have the second draw-in groove 321, and the other end has the second protuberance 322.The first protuberance 311 can splice with the second draw-in groove 321.
As shown in Figure 3, backlight 3 is spliced by the first backlight assembly 31 and the second backlight assembly 32.Backlight 3 also can be spliced by a plurality of backlight assemblies, thereby forms various shapes.
The utility model also provides a kind of lamp box that uses above-mentioned backlight.Preferably, backlight is welded on the base plate of described lamp box.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make many changes or being modified to the equivalent example of equivalent variations, all still belong within the scope of the technical scheme that the utility model is new.
