Abstract

The utility model relates to a novel electronic luminous panel, composed of a casing, a light guide plate, a control circuit, and a light source. The casing is formed by the injection moulding of AS plastics, the front side of the light guide plate is polishing and plane buffed transparent plexiglass, the light source is positioned at the lateral face of the light guide plate, and a luminous plate is formed after the power is switched on and the light is emitted, the luminous plate is arranged in the casing, and the luminous panel can be formed by covered character patterns or figures on the panel. The utility model can be used for magnified number plates of motor vehicles, door plates, other various indicating plates, etc., and has the advantages of simple fabrication and low cost.

Description

Photoconduction formula electron luminescence label

The utility model relates to a kind of novel photoconduction formula electron luminescence label.

All in the market various labels generally speaking, can be divided into passive light source and recognize formula and two kinds of active light source identifying types.Though the former makes simple, and is not luminous because of itself, can recognize that under extraneous irradiate light so dark or be beyond recognition night at light at all, what lost label should have effect.The latter mostly is lamp box or neon bulb formula greatly, though all can see night on daytime, because of making complexity, power consumption is big, and the cost height is so except that some billboards can use, most of label all can't use.

The purpose of this utility model is a kind of active light source identification that can be luminous voluntarily of design, manufacture craft is simple, easy to use, power consumption is little, the life-span is long, and cost is very cheap, no matter has nowhere boundary's light source all can clearly recognize, and can send the photoconduction formula electron luminescence label of multiple color.

The utility model is realized with following scheme: one-piece construction comprises housing, light guide plate, light source, control circuit and font or figure coverage rate etc., and its middle shell is to become the case structure that a panel and drain pan can be buckled in one by the engineering plastics injection moulding.It is characterized in that: light guide plate is positive to be sanding face, and light source is positioned at the side of light guide plate.There are font, figure cover plate in the front of light guide plate, and there is a reflector of being made by reflectorized material at the back side of light guide plate.Light source is the electron luminescence diode, is positioned at one to three side of light guide plate.Light source can be made up of the electron luminescence diode of multiple color.Light guide plate can be made up of polylith, different colours.

The utility model has the advantages that: 1. under the different condition of bright and dark light, all can clearly recognize label; 2. compare with existing active light source identification label, make simply, power consumption is little; Cost is low; 3. applied widely, be not only applicable to label, also can be used for billboard, Automobile registration etc.

Introduce the utility model in detail below in conjunction with accompanying drawing.

With reference to accompanying drawing: one-piece construction comprises housing, light guide plate, light source, control circuit and font or figure coverage rate etc. (as shown in Figure 2), its middle shell 11 is to become the case structure that a panel 12 and drain pan 13 can be buckled in one by the engineering plastics injection moulding, panel is an AS plastic, transparent body, drain pan is a metal material, the following of panel is that one deck is made with printing or the mode of cliping and pasting, the signage content 14 that shows with font or graphics mode covers on the light guide plate 15, signage content is open letters or hollow figure, so that the light on the light guide plate can be appeared from hollow position, form luminous characters or figure.Light guide plate is a transparent organic glass, and its two plane is formed numerous reflection light point (as shown in Figure 1) by hacking, and this densities of points of light increases promptly becomes a light-guiding plane.Control circuit when being applied on the motor vehicles amplification number plate, for mechanical linkage control (Fig. 5), is light-operated circuit (Fig. 6) when being applied on doorplate or the road sign according to the design of label needs.

Principle of work of the present utility model is as follows:

Light is propagated with linear fashion in light conductor, when running into the interface, can produce reflection and refraction, its incident angle equals reflection angle, as shown in Figure 1, if on a side of light conductor, open a groove, equal in the rectilinear propagation process of light, to have increased an interface, at this moment light meet this interface can produce the reflection and the refraction, thereby form the light district at this interface, if the density of groove is increased, just then the light district can form a planar light plate structure.The utility model is promptly used this optical principle, and two face hackings with tabular optical conductor equal to have left numerous smooth groove, when light when the end face of light guide plate is injected, whole light guide plate just can be luminous, forms a planar light source.Not enough as brightness, can also inject light from two ends, or near character or figure, increase light source.

As be applied on the vehicle license, circuit is controlled as shown in Figure 5: amplify the number plate positive and negative electrode respectively by ignition switch and vehicle accumulator is positive and negative joins, side marker light minus earth, positive pole turn to left and right vehicle wheel respectively and brake system is joined.When vehicle launch, whole license number will be luminous, driving at night, hundred meters parts of label number are high-visible, and when vehicle turned to the left or to the right, the side marker light on the label is correspondingly indication to the left or to the right also, during brake, pilot lamp is simultaneously luminous, has brought into play the effect of high-mount stop lamp.

As be applied on doorplate or the various Pointing sign board, then the circuit control principle as shown in Figure 6, the external plug of label.Can directly be inserted on the 220v power supply and use.Reduction voltage circuit and mu balanced circuit reduce power source voltage significantly and are controlled in certain scope, when whole label is worked, power consumption is not more than 2w, a built-in light-operated circuit, the may command label by day or light extinguish automatically when strong, automatically luminous when night or light are more weak, so that make the people no matter all can clear identification under light or half-light environment.
