Description
[technical field]
The invention relates to a kind of illuminant sign plate.
[background technology]
Nameplate (Logo) is as billboard, vehicle emblem and traffic indication board, and is extensive day by day with the coml purposes in public places.Yet nameplate itself can not be luminous, need to rely on the light of reflection ambient lighting device just can make the people also can see literal and pattern on licence plate or the billboard clearly at night.For this reason, initiatively light source is set at the nameplate back side usually, the light that this light source sends illuminates nameplate from the back side, thereby need not the exterior lighting device.The back side is provided with initiatively, and the nameplate of light source is commonly referred to illuminant sign plate.
Present most illuminant sign plate comprises light-emitting device and mark, illuminates mark by light-emitting device and reaches the demonstration purpose, yet have problems such as display effect is not good mostly.
For realizing that mark obtains clear demonstration, is easy to identification, and the light that light-emitting device sent is fully used, avoid causing the purpose of energy loss, it is good that the light-emitting device of illuminant sign plate possesses the characteristics that the light that can produce high brightness, the light-emitting zone with different brightness and light is fully used.
A kind of illuminant sign plate of prior art is exposed in No. the 6th, 174,075, the United States Patent (USP) of January 16 calendar year 2001 bulletin, as shown in Figure 1.This illuminant sign plate 100 comprises a light-emitting device 130 and a mark 110, this light-emitting device 130 comprises PVC (Polyvinylchloride) plate 131 and light supply apparatus 133, one groove 135 is arranged at PVC plate 131 bottoms, be used to accommodate light supply apparatus 133, this light supply apparatus 133 mainly is to be made of light emitting diode 137, and this mark 110 is attached on PVC plate 131 surfaces.When light supply apparatus 133 was luminous, light was injected PVC plate 131 and is dispersed by it, illuminates attached to its surperficial mark 110.
This illuminant sign plate 100 comes with some shortcomings: at first, PVC plate 131 is three-dimensional shapes, partly light can be from the side 136 of PVC plate 131 but not the surface penetrate, can't expose to mark 110, therefore, light be not fully utilized and energy loss serious.Secondly, in the light-emitting device 130, the light emitting diode 137 of light supply apparatus 133 is pointolites, its emergent ray is that the summit is the circular cone distribution with this light emitting diode 137, as observer during from mark 110 top views, this mark 110 is only fully illuminated in a border circular areas, promptly, these mark 110 each point light intensity differ, and brightness is even inadequately.
[summary of the invention]
In order to overcome the big and luminous uniform inadequately problem of prior art illuminant sign plate luminous energy loss, the invention provides the less and luminous illuminant sign plate uniformly of a kind of luminous energy loss.
The technical scheme that technical solution problem of the present invention is adopted is: an illuminant sign plate is provided, it comprises a light-emitting device, a reflex reflector and a sign panel, this sign panel is supported on this reflex reflector, it comprises a pattern and a transparent body, the edge of this reflex reflector has the ccontaining cavity of a spill, and this light-emitting device is housed in the ccontaining cavity of this spill.
Compare with prior art, illuminant sign plate of the present invention is by light-emitting device, reflex reflector and sign panel are formed, the light that light-emitting device is launched is evenly penetrated by the transparent body of sign panel after the reflectance coating reflection of reflex reflector and sign panel, and its reflecting effect and light utilization efficiency all have raising than prior art, therefore can improve the contrast of pattern when luminous demonstration of illuminant sign plate, highlight effect, make pattern clear, be easy to identification, and can reduce because the light energy losses that pattern absorbs and scattered light is brought strengthens the brightness of pattern.

Fig. 2 is the cut-open view of illuminant sign plate of the present invention.
Fig. 3 is the vertical view of illuminant sign plate of the present invention.
Fig. 4 is the light ray propagation synoptic diagram of illuminant sign plate of the present invention.
[embodiment]
Seeing also Fig. 2 and Fig. 3, is the cut-open view and the vertical view of illuminant sign plate one embodiment of the present invention.This illuminant sign plate 300 comprises a sign panel 301, a light-emitting device 311 and a reflex reflector 320.Sign panel 301 can be a flexible material, is attached to reflex reflector 320 tops.
This sign panel 301 comprises the transparent body 302, diffusion layer 303 and pattern 304, and wherein pattern 304 contiguous these light-emitting device 311 one sides are provided with reflectance coating 305.
This transparent body 302 should select the high material of transmittance to make as far as possible, the size of its outer shape, thickness and volume is to decide according to the actual requirements, when requiring lower or not adopting diffusion layer 303, also available trnaslucent materials processes, reflective processing should be done in its side, during monochromatic the use, for increasing the weight of its colourity or polychrome sense, the also available material that has color is made.
This diffusion layer 303 is light-emitting device 311 issued light lines are spread and to reflect, the light that makes light-emitting device 311 send is eliminated non-uniform phenomenon on its surface, it is located at the transparent body 302 internal layers, can be to grind to form, and also available chemical reagent is made through diffusion or corrosion.
The shape of this pattern 304 can the time be decided according to demand by design, and it comprises pattern body 306 and non-pattern body 308, and this non-pattern body 308 is set to transparent or semitransparent, is used for seeing through the light of selfluminous device 311.This pattern 304 can be set directly at the transparent body 302 towards the surface of light-emitting device 311 or be arranged on the surface of this diffusion layer 303 towards light-emitting device 311.
This light-emitting device 311 can adopt three kinds of light-emitting components of red, green, blue, also can be only with a kind of light-emitting component of or other any colors, it can be a plurality of light emitting diodes, also can be light sources such as EL part, and decide according to the actual requirements the quantity and the position of light-emitting component.
This reflex reflector 320 comprises a pedestal 321 and reflector plate 322, the inside surface that this reflector plate 322 is attached to this pedestal 321 is used for reflecting the light that selfluminous device 311 is sent, improve the luminosity of sign panel 301, this pedestal 321 and sign panel 301 are fitted and connected.
The edge of this reflex reflector 320 has the ccontaining cavity 307 of a spill, and this light-emitting device 311 is to be housed in this ccontaining cavity 307.
Seeing also Fig. 4, is the light ray propagation synoptic diagram of illuminant sign plate of the present invention.Light-emitting device 311 be driven luminous after, light is incident to the diffusion layer 303 of sign panel 301 after more than 305 reflection of reflex reflector 320 and reflectance coating, and by diffusion layer 303 with light scatter, finally penetrate illuminant sign plate 300, reach luminous display effect.The color of the wherein adjustable electro-optical device 311 of haircuting makes the light-emitting zone color different with brightness with brightness, and quantity of light source can require to increase according to luminosity.
It is described that illuminant sign plate of the present invention is not limited to present embodiment.See also Fig. 2 again, sign panel 301 also can be that hard material is fixed on reflex reflector 320 tops by buckle or screw thread.In addition, this pedestal 321 also can be made by the highly reflective material and be used as reflex reflector 320, or these pedestal 321 surface coated one deck reflectance coatings reach the purpose of reflection ray.
