Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, a self-luminous sign, which can be a traffic sign such as a square, triangle or circle, comprises a pattern layer 1, a light guide plate 2, a reflective film 4, an aluminum plate 5 and a fixing device 6 for connecting the above components together, wherein the pattern layer 1, the light guide plate 2, the reflective film 4 and the aluminum plate 5 are flat plates with consistent shapes and small size differences; the pattern layer 1 is a reflective film layer with a mark information pattern; the light guide plate 2 is made of optical acrylic/PC (polycarbonate) plates, then high-tech materials with extremely high reflectivity and no light absorption are used, light guide points are engraved on the optical acrylic plates by laser, the optical acrylic plates are used for absorbing the light emitted from a lamp to stay on the surfaces of the optical acrylic plates, when the light reaches each light guide point, the reflected light can be diffused at each angle, then the reflection condition is destroyed to be emitted from the front surface of the light guide plate 2, and the light guide plate 2 can uniformly emit light through the light guide points with various densities and sizes; the reflecting film 4 is used for reflecting the light exposed from the bottom surface back to the light guide plate 2 to improve the use efficiency of the light, so that the light emitting efficiency is high and the power consumption is low under the condition of the same area light emitting brightness; the aluminum plate 5 is arranged at the tail end and is mainly used for supporting the whole device and is connected with a bracket or a fixing column, so that the device is fixed at a required position; a light source 3 is arranged on one side close to the edge of the light guide plate 2, and the light guide plate 2 is uniformly illuminated by the light source 3 to illuminate the content displayed on the pattern layer 1.

In a specific embodiment, the light source 3 is an LED strip, and the LED strip is formed by assembling LEDs on a strip-shaped FPC (flexible printed circuit) or PCB (printed circuit board), and is named after the shape of a product is like a strip, so that the LED strip has the characteristics of long service life (generally, the normal service life is 8 to 10 ten thousand hours), energy saving, and environmental protection.

In a specific embodiment, the fixing device 6 is a groove plate clamped at the edges of the pattern layer 1, the light guide plate 2, the reflective film 4 and the aluminum plate 5, and the pattern layer 1, the light guide plate 2, the light source 3, the reflective film 4 and the aluminum plate 5 are sequentially placed in a groove of the groove plate.

In a specific embodiment, the light sources 3 are disposed in grooves formed on the front or back surface of the light guide plate 2, and the light emitting direction of the light sources 3 faces the center direction of the light guide plate 2.

In a specific embodiment, as shown in fig. 2, the groove depth dimension of the groove plate is greater than the length dimension from the light source 3 setting position to the edge of the light guide plate 2, so that the side plate of the groove plate shields the vicinity of the light source 3, and the influence on the light emitting uniformity of the whole sign caused by the fact that the light source 3 or the light guide plate 2 at a position close to the light source 3 is too bright is reduced.

In a specific embodiment, as shown in fig. 3, the light sources 3 are disposed in grooves or notches disposed on the side surfaces of the light guide plate 2, and the light emitting direction of the light sources 3 faces the center direction of the light guide plate 2.
