Description

[Detailed description of the invention] Industrial application field The invention relates to a color electronic display device installed in stadiums, streets, etc., and uses a large number of sets of light-emitting elements of the three primary colors of light to display images, characters, etc. is displayed.

Conventional configuration and its problems The configuration of a conventional color electronic display device has a large number of bar-shaped bodies arranged in parallel, and a large number of sets of light emitting elements of the three primary colors of light are spread over two adjacent bodies. Therefore, the light emitting elements are arranged in one row in each main body, so the unitization of the unit display is insufficient, and there is no means to connect and fix an even number of them. There is a problem that it is not possible to form a set of three primary colors of light, and the wiring work for supplying the electric signal to blink the light emitting element is complicated, resulting in problems such as difficulty in assembly and handling. Furthermore, due to the heat generated by the light-emitting elements arranged in a high density, sufficient attention must be paid to the heat resistance of the socket, and an expensive material with extremely high heat resistance must be used.

Purpose of the invention The present invention solves these problems at once, and provides a color electronic display device in which a plurality of unit displays are arranged vertically and horizontally to appropriately configure a set of light-emitting elements for the three primary colors of light. The present invention has the purpose of simplifying the structure and facilitating assembly and handling, and also has the purpose of enhancing the heat dissipation effect of the socket.

Structure of the Invention In order to achieve this objective, the present invention has unit displays in which multiple sets of light-emitting elements of the three primary colors of light are arranged in two rows, vertically and horizontally, on the front surface of a single main body through sockets. The color electronic display device is characterized in that a plurality of sockets are arranged, and the side edges of the sockets respectively protrude from the upper and lower edges of the main body, and are configured to allow ventilation between the unit displays, By suitably configuring a set of three primary color light emitting elements, the configuration is simplified and the heat dissipation effect of the socket is enhanced.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

A is a unit display, and a color electric light display device is constructed by installing a plurality of unit display units vertically and horizontally. Reference numeral 1 denotes a single main body constituting unit display A. The outer shell is made of plastic, metal, etc., a printed circuit board constituting a control circuit is housed inside, and a cable 1' is routed from the rear. . Reference numeral 2 denotes a socket made of synthetic resin, which is provided either integrally or separately on the front surface of the main body 1. Through the socket 2, the three primary colors of light, R (red), G (green), and B (blue) are transmitted. ) light emitting element 3R,
A large number of sets of 3G and 3B are arranged across two rows. The side edges of the sockets 2, that is, the upper side for the sockets arranged in the upper row of the unit display A, and the lower side for the sockets arranged in the lower row of the unit display A, protrude from the upper and lower edges of the main body 1, respectively. A blower (not shown) provides ventilation between the sockets 2 and 3, thereby significantly enhancing the heat dissipation effect of the socket 2. In addition,
In this embodiment, light emitting elements 3R, 3 of three primary colors of light are used.
The sets G and 3B consist of one light emitting element of each color arranged in an equilateral triangle shape, and therefore both side edges 1a and 1b of the main body 1 form an oblique shape along the arrangement of the light emitting elements, Horizontally adjacent unit display A
High-density mounting is achieved by enabling close contact with the light emitting elements 3B, but it is also possible to make two light emitting elements 3B, which have a relatively weak light output, and arrange them in a square with the light emitting elements 3R and 3G. In this case, both side edges of the main body 1 do not need to be formed in an oblique shape. It goes without saying that it is better to install a plurality of unit displays A in a housing or the like to form a module, and to configure a display device by installing a plurality of these modules.

Effects of the invention The invention described above uses a single main body as a unit display which is a component of a color electric display device.
A large number of sets of light emitting elements of the three primary colors of light are arranged in two rows on the front of the main body via sockets. This makes it possible to appropriately configure a set of three primary color light-emitting elements, which contributes to simplifying wiring work, making assembly and handling easier.Furthermore, the side edges of the socket are Because they protrude from the upper and lower edges of the socket, the heat dissipation effect of the socket is significantly increased due to ventilation, and the socket is made of synthetic resin with a low heat resistance.
This can have effects such as contributing to cost reduction.
