Abstract

The utility model relates to an automotive luminous number plate, which is composed of a housing, a light conducting plate, a control circuit and light source. The housing is injected to be molded by AS plastics. The front surface of the light conducting plate is transparent organic glass with a roughened polished plane. The light source is arranged on the side face of the light conducting plate and a luminous plate can be formed after the light conducting plate is energized. Then the energized light conducting plate is arranged in the housing, which enables a luminous number plate to be formed by covering characters or patterns on a panel. The utility model has the advantages of convenient fabrication and low cost.

Description

The power actuated vehicle luminous license plate

The utility model relates to a kind of novel automobile luminous license plate.

Current mobility vehicle luminous license plate is that passive light source is recognized formula but is not luminous because of itself, under extraneous light irradiation, can recognize, so at light dark or identification at night difficulty.

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 power actuated vehicle luminous license plate of multiple color of light.

The utility model is realized with following scheme: integral structure comprises housing, LGP, light source, control circuit and font or figure protection face 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: LGP is positive to be sanding face, and light source is positioned at the side of LGP.There are font, figure cover plate in the front of LGP, and there is a reflector of being made by reflex-reflective material at the back side of LGP.Light source is the electron luminescence diode, is positioned at one to three side of LGP.Light source can be made up of the electron luminescence diode of multiple color.LGP 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. make simply, power consumption is little; Cost is low; 3. applied widely, be not only applicable to Automobile registration, label, also can be used for advertising panel etc.

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

With reference to accompanying drawing: the utility model integral structure comprises housing, LGP, light source, control circuit and font or figure protection face etc. (as shown in Figure 2), its middle shell 9 is to become the case structure that a panel 12 and drain pan 11 can be buckled in one by the engineering plastics injection moulding, panel is an AS plastic, transparent body, drain pan is a metallic material, the following of panel is that one deck is made with printing or the mode of cliping and pasting, the signage content 10 that shows with font or graphics mode covers on the LGP 1, signage content is open letters or hollow figure, so that the light on the LGP can be appeared from hollow position, form luminous characters or figure.LGP is a transparent organism 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 is according to the design of label needs, when being applied on the power actuated vehicle amplification number plate, as shown in Figure 6.

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 angle of incidence equals angle of reflection, 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 LGP is injected, whole LGP 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.

Circuit is controlled as shown in Figure 6: luminescence scutcheon is powered by a booster, booster input end and automobile lampet power supply (+12V) join output 30～110V, 400～1000Hz alternating current.
