Transparent material photoelectric display device

Abstract

The invention is a kind of transparent material photoelectric displaying device. The character lies in: it includes the transparent material photoelectric displaying screen, the radiation light source, and the fixing device for the light source. The base structure of the screen is a transparent parallel board; it also can be the transparent pipe structure or transparent arc structure, there has the transparent or semitransparent concave, convex pattern or word on its surface or in the screen, the radiation light source is fixed on edge of the cross section of the screen through the fixing device. The beam of the light source enters the screen from the cross section edge with angle greater than or equal to the critical angle of the transparent material. The structure is simple; the quantity of the elements is little. The cost is low.

Description

Technical field: [0001] The invention relates to a photoelectric display screen, in particular to a transparent material photoelectric display device. It is mainly used in the manufacture of indoor and outdoor advertising luminous display screens. Such as indoor nameplates, billboards, signs, outdoor road signs, billboards, nameplates of companies and other units, static or dynamic luminous display of facades and window advertisements of shopping malls, hotels, etc., etc. Background technique: [0002] There are many traditional decorative lighting methods for indoor and outdoor advertising, such as neon lights and fiber optic lighting systems. The characteristics of neon lights are: they can be made into any shape and display a variety of colors, and the length of the lamp tube can also be precisely controlled. However, neon lamps must work under high voltage (about 9-12kv), so electrical safety must be paid attention to when using them, and their manufacturing process is...

AI Technical Summary

Problems solved by technology

For side-emitting optical fiber, due to the refraction of light during transmission, attenuation will occur, and uneven brightness will be caused when the transmission distance is too long

Fiber optic lighting is relatively dark, suitable for use in places where the ambient brightness is not too high, otherwise the display effect is not ideal

Whether it is a neon light or an optical fiber lighting system, when it is made into a display screen, it must be inlaid or installed on the graphic surface that needs to be illuminated. The manufacturing process is relatively complicated, the cost is high, and it affects the visual effect during the day.
