Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting type sign such as a road sign or a safety sign.

[0002]

2. Description of the Related Art For example, as a road sign, a reflective sign constructed so as to reflect the illumination light of an automobile so that the display shape can be seen at night, and a light bulb arranged corresponding to the display shape are continuously provided. 2. Description of the Related Art There is a light-emitting type that is configured to emphasize a display by turning on the light or blinking the light corresponding to the display.

Further, as an indicator in an underground mall, a station, a building, etc., there is a light emitting type in which a fluorescent lamp or a light bulb is installed in a casing having a transparent plate for display on the front side.

[0004]

However, such a conventional sign has the following problems. With a reflective sign, the display may be difficult to see depending on the angle of illumination light and the like. The light-emitting type has drawbacks in terms of durability, power consumption, heat dissipation, and miniaturization of a light bulb or a fluorescent lamp. The present invention aims to solve such problems.

[0005]

In order to solve the above-mentioned problems, in the present invention, a plurality of LED chips are scattered on the surface of the substrate so as to correspond to the inside of the contour of the desired two-dimensional display shape of the sign. The plurality of LED chips are integrally molded with a transparent resin, and the molded transparent resin has a shape corresponding to the two-dimensional display shape, and the substrate is transparent on the front side. We propose a luminescent sign device that is constructed by storing in a weatherproof container provided with a light plate.

Further, in the present invention, it is proposed that the two-dimensional display shape has a plurality of different regions in the light-emitting marker device having the above-mentioned structure, and that LED chips of different emission colors are respectively arranged and mounted. To do.

Further, in the present invention, it is proposed that the surface of the substrate corresponding to at least the inside of the outline of the two-dimensional display shape is white in the light emitting type marking device having the above-mentioned configuration.

Further, in the present invention, it is proposed that in the light emitting type labeling device having the above structure, the weather resistant container is supported by a supporting member provided on the base. The supporting member is a support pipe standing on the base, and a lighting control unit and a power source are formed on the base side, and the lighting control unit and the power supply and the LED chip in the weatherproof container are passed through the support pipe. We suggest connecting by wiring.

Further, the present invention proposes that the lighting control unit and the battery are housed in the weatherproof container together with the substrate and can be independently installed in the light-emitting marking device having the above-mentioned structure.

[0010]

The light generated from the plurality of LED chips mounted on the surface of the substrate passes through the transparent resin layer that molds the plurality of LED chips and radiates from the transparent plate to the outside of the weatherproof container. To do. In this way, the transparent resin layer can be entirely illuminated by the light passing therethrough, that is, can emit a two-dimensional display shape. At this time, by forming the surface of the substrate corresponding to the inside of the outline of the two-dimensional display shape to be white, the light emission of the two-dimensional display shape can be efficiently performed.

Since the substrate on which the LED chip is mounted is stored in a weatherproof container, it can be used not only indoors but also outdoors for a long period of time, and can be used as various types of road signs or safety signs. And the like can be used as a luminescent label.
