Abstract
The utility model relates to a light distribution structure of an LED guideboard. The light distribution structure comprises a rectangular frame, a light permeable panel is mounted on the front of the frame and LED lamp panels extending rightwards and leftwards are respectively mounted on the inner sides of the upper side and the lower side of the frame, a reflector is arranged on the back of the frame, and a transverse light guide board is fixed in front of the reflector. The LED lamp panels are used in the light distribution structure as the light source and are low in power. Reducing the thickness of the frame and cutting the cost can be realized by arranging the light source on the flank of the frame. Using the reflector, the light guide board and the light permeable panel to uniformize the light can distribute light more evenly and make characters on the guideboard clearer.
Description
Technical field
The utility model relates to active light-emitting type traffic indication guide board, and is specifically a kind of with the LED guideboard light distribution structure of LED as light source.
Background technology
Existing active light-emitting type guideboard mostly is greatly the back form that fluorescent tube is light source is housed.The shortcoming of this guideboard is that thickness is thick, heavy, non-uniform light, and power large, waste energy.
And the utility model uses adopting surface mounted LED as light source in the mode of lateral emitting, reduces the thickness of guideboard, and is lightweight, and inner reflective homogenize structure is so that guideboard is luminous more even.
Summary of the invention
The utility model provides a kind of thickness little, the luminous even and little LED guideboard light distribution structure of power for the problems referred to above.
According to the technical solution of the utility model: a kind of LED guideboard light distribution structure, the framework that comprises cuboid, the front of described framework is equipped with light penetrating panel, the LED lamp plate that extends about the inboard of two sides is separately installed with about the described framework, the back of described framework is equipped with reflector, and the front of described reflector is fixed with horizontal LGP.
The place ahead of described LED lamp plate is provided with and is fixed on the up and down shadow shield of inboard, two sides of described framework.
Described LED lamp plate is aluminium base lamp plate, and its LED that uses is adopting surface mounted LED.
The back side of described LED lamp plate is equipped with radiator.
The front of described reflector is coated with the diffuse reflection reflecting coating.
The front of described LGP is diffuse surface, and the surface configuration of described diffuse surface is curved surface or ladder plane.
The longitudinal section of described LGP is drift angle V font forward.
The material of described light penetrating panel is PC or lucite.
The material of described framework is metal or plastics.
Technique effect of the present utility model is: the utility model adopts the LED lamp plate as light source, and power is little; Light source arrangement at frame facet, can be reduced the thickness of framework, save cost; Adopt reflector, LGP and light penetrating panel homogenize light, make guideboard luminous more even, that the guideboard character shows is more clear.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Among Fig. 1, Fig. 2, comprise framework 1, LED lamp plate 2, shadow shield 3, reflector 4, LGP 5, light penetrating panel 6 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of LED guideboard light distribution structure, comprises the framework 1 of cuboid, and the material of framework 1 is metal or plastics, and can also there be the decoration bound edge its outside.
The front of framework 1 is equipped with light penetrating panel 6, and the material of light penetrating panel 6 is PC or lucite, has the effect of homogenize emergent ray.
The LED lamp plate 2 that extends about the inboard of framework two sides about in the of 1 is separately installed with, LED lamp plate 2 is aluminium base lamp plate, its LED that uses is adopting surface mounted LED.The back side at LED lamp plate 2 can also be equipped with radiator.The place ahead of LED lamp plate 2 also is provided with the shadow shield 3 that is fixed on framework inboard, two sides about in the of 1, can hide the LED bright spot of seeing through light penetrating panel 6.
The back of framework 1 is equipped with reflector 4, and the front of reflector 4 is coated with the diffuse reflection reflecting coating.The front of reflector 4 is fixed with horizontal LGP 5, and LGP 5 preferably is positioned at the centre position of reflector 4 fronts.The front of LGP 5 is diffuse surface, and the surface configuration of diffuse surface is curved surface or ladder plane.The longitudinal section of LGP 5 is drift angle V font forward.
Operation principle of the present utility model and the course of work are as follows: LED lamp plate 2 is incident upon light on the reflector 4 after the diffuse reflection surface homogenize of reflector 4, is assigned to equably light penetrating panel two parts about in the of 6; LED lamp plate 2 is incident upon the light on the central LGP 5, after the diffuse reflection surface homogenize of LGP 5, is assigned to equably the middle body of light penetrating panel 6, has remedied the partially dark defective of central authorities; In addition, because light penetrating panel 6 itself also has the effect of certain homogenize light, therefore, obtained the LED guideboard of a surface energy uniformly light-emitting.
The utility model adopts LED lamp plate 2 as light source, and power is little, but energy savings; With the side of light source arrangement at framework 1, can reduce the thickness of framework 1, save cost; Adopt reflector 4, LGP 5 and light penetrating panel 6 homogenize light, make guideboard luminous more even, that the guideboard character shows is more clear.
