Description

[Detailed description of the invention] The present invention relates to an electronic display device.

Electric display devices, which have a large number of light emitting elements arranged vertically and horizontally, are mainly installed in stadiums and streets, and are configured to display images and messages using electrical signals. is installed horizontally. Therefore, if it is installed above the spectator seats in a stadium or on the wall of a building, the amount of light will decrease due to the directivity of the light emitting element because it is located above the viewer's view, resulting in poor clarity. Significant decline occurs. Note that if the directivity of the light-emitting element is wide, this will not happen, but since the luminous intensity of the light-emitting element must be increased by the widening of the directivity, there will be a significant increase in power consumption, which is not economically viable. It is disadvantageous.

The present invention has been made in view of these drawbacks, and aims to improve clarity and eliminate unnecessary power consumption by providing a configuration in which the light emitting element can be tilted downward.

Hereinafter, the present invention will be explained based on examples.

1 and 2 show a first embodiment, in which reference numeral 1 denotes a vertical and straight support column, which is constructed of an L-shaped metal fitting. Reference numeral 2 denotes a large number of long box-shaped unit members, made of extruded aluminum material, for example, and mounted with screws or the like at predetermined intervals perpendicular to the column 1. In addition,
The wiring cable is stored inside. Numeral 3 denotes a large number of sockets arranged on the front surface of the unit member 2. In addition, 4 is a waterproof gasket, which is attached to the unit member 2.
and socket 3. 5 is socket 3
A light emitting element 6 is attached to the socket 3 by passing through the waterproof ring 5.

In this embodiment, by tilting the mounting surface of the unit member 2 to the support column 1, that is, the back surface of the unit member 2, the light emitting element 6 mounted in the socket 3 is tilted downward at an angle θ.
In the figure, d ₁ is the mounting distance between the unit member 2 and the support column 1, and d ₂ is the distance between the light emitting elements 6. Since d ₁ > d ₂ , the display density (and mixing degree in the case of a color display device) is improved. The fact that d ₁ is larger than d ₂ , which is set at a considerably narrower interval, allows the installation interval of the unit member 2 to the support column 1 to be set with more leeway, which is a great advantage in terms of construction.

FIG. 3 shows an electric display device 7 according to the present invention installed above the bleachers 8 of a stadium, and although it is installed obliquely above the spectators 9, the light emitting elements 6 are not visible to the spectators. 9, it faces almost directly in front of the screen and provides a clear display.

FIG. 4 shows a second embodiment, in which the front surface of the unit member 2 is tilted so that the light emitting element 6 mounted in the socket 3 is tilted downward at an angle θ.

The present invention is configured as described above, and the gist thereof is as follows:
A vertical and straight support, a large number of elongated unit members perpendicular to the support and mounted on the back at predetermined intervals, a large number of sockets arranged on the front of this unit member, and a number of sockets to be attached to the sockets. and a light-emitting element mounted in the socket, the light-emitting element mounted in the socket is tilted downward by tilting the back surface or tilting the front surface of the unit member. ,
It has the following excellent effects.

(1) Since the light-emitting elements are installed tilted downward, viewers looking up diagonally can obtain a clear display with sufficient light.

(2) Since the back or front of the unit member is tilted, a straight support can be used to attach the unit member, making it easy to manufacture the support and making it easier to attach the unit member to the support. The mounting structure is simplified and costs can be reduced.

(3) Since long unit members are used, handling is advantageous in terms of production.

(4) Since there are gaps between unit members, ventilation is easy (air may be blown from the rear), improving the cooling effect.

(5) Since it is only necessary to incline the back or front of the unit member, troublesome processing such as inclining the back of the socket is unnecessary, which is advantageous in terms of production. That is, the unit member can be easily manufactured into any shape using extruded aluminum material or the like.
