本発明は電光表示用外光遮光装置に係り、たとえば競技

表示の左右方向の視認角を大きくした外光遮光装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an external light shading device for electronic display, which blocks external light entering an electronic device installed in an outdoor facility such as a stadium, and improves the contrast of the display surface. The present invention also relates to an external light shielding device that increases the viewing angle in the horizontal direction of the display.
一般tごこの種の電光表示装置lこおいては、発光体と
して電球、陰極線管、けい光ランプなどが用いられてい
る。しかし、これら発光体のみで表示面を形成したもの
では、昼間日光の直射を受けるとコントラストが悪くな
り、表示を確認し難くなる。このため、たとえば実公昭
57−39847号公報に見られるように、表示ランプ
の前面に多数の水平格子板を有する遮光器を設けたもの
が提案された。In general, this type of electronic display device uses a light bulb, a cathode ray tube, a fluorescent lamp, etc. as a light emitting body. However, when the display surface is formed only from these light emitters, the contrast deteriorates when exposed to direct sunlight during the day, making it difficult to confirm the display. For this reason, it has been proposed, for example, as seen in Japanese Utility Model Publication No. 57-39847, that a light shield having a large number of horizontal grid plates is provided in front of a display lamp.
このものは、ランプの上方側から入射される日光の直射
光などは格子板によって遮えぎられるため、コントラス
トが良くなることが確認されている。しかしながら、こ
のものは水平格子板が細長の平板状で形成されているの
で、左右方向の視認角が水平格子板周辺部で制限される
ため狭く、シや光器で遮光されて視認角は約100’〜
12o0となり、広い競技場などでは、表示装置の正面
から外゛れると視認できなくなるおそれがあり、広範囲
から視認できるものが要望されている。It has been confirmed that this type of lamp has good contrast because the lattice plate blocks direct sunlight that enters from above the lamp. However, since the horizontal lattice plate is formed into an elongated flat plate, the viewing angle in the left and right direction is narrow because it is limited around the horizontal lattice plate, and the visibility angle is approximately 100'~
12o0, and in a large stadium or the like, there is a risk that it will not be visible if it is removed from the front of the display device, so there is a demand for something that can be seen from a wide range.
本発明は上述の事情を考慮して″なされたもので、外光
の遮光効果を損なうことなく、左右方向の視認角を広く
でき、広範囲から表示が視認できるようにした電光表示
用外光遮光装置を提供することを目的とする。The present invention has been made in consideration of the above-mentioned circumstances, and provides an external light shielding device for electronic displays that can widen the viewing angle in the left and right directions without impairing the external light shielding effect, and make the display visible from a wide range. The purpose is to provide equipment.

Reference numeral 3 denotes a cylindrical container having a light projection opening 4 on the front surface, and this container 3 is attached to a display device (not shown). Then, the light emitting body 1 is housed in the container 1 with the light emitting display section 2 positioned on the light emitting opening 4 side. 5 is a louver, and this louver 5 is a container 3
An annular frame portion 6 having an inner surface that is flush with the inner peripheral surface of
The frame portion 6 is formed with a plurality of louver pieces 7 spaced apart from each other in the vertical direction and horizontally in the left and right direction.

The louver pieces 7b+7c+7d+7e located in the vertical direction are arranged so that their protruding lengths are made longer and the protruding lengths of the louver pieces 7b+7c+7d+7e are sequentially made shorter. This is done by forming each louver piece 7 with a different radius of curvature, with the louver piece 7a having a large radius of curvature located in the middle, and the louver piece 7b having a smaller radius of curvature,
7c... may be provided. Further, in this embodiment, one louver piece 7b' is provided on the lower side. and,
Louver pieces 7b+7c+7 arranged in the upper half of the louver 5
cL7e is approximately 45 degrees at a light shielding angle θ formed by a line A connecting the front edge 8 of the upper louver piece and the rear edge 9 of the adjacent lower louver piece and a line B extending horizontally forward. It is formed to be. 10 is a connection terminal.
つぎに、この実施例の作用について説明する。Next, the operation of this embodiment will be explained.
発光体1がルーバ5によって遮光される遮光角θはほぼ
45°となっているため、発光体1への太陽の直射光の
入射が遮断されてコントラストが良好となる。そうして
、ルーバ5のルーバ片7は円弧状に形成されているので
、発光体1の発光表示部2が容体3の投光開口4より外
方に突出され、左右方向の視認角ψが約220°となり
、表示装置の表示面に対して直積に近い位置からの視認
も可能となる。しかも、発光体1の発光表示部2が容体
3の投光開口4から前方に突出されるので、光出力が大
きくなって表示面が明るくなり、視認し易くなる。Since the light shielding angle θ at which the light emitter 1 is shielded from light by the louver 5 is approximately 45°, direct sunlight from entering the light emitter 1 is blocked, resulting in good contrast. Since the louver piece 7 of the louver 5 is formed in an arc shape, the light emitting display part 2 of the light emitter 1 is projected outward from the light emitting opening 4 of the container 3, and the viewing angle ψ in the left and right direction is The angle is approximately 220°, and it is possible to view the angle from a position close to the direct product of the display surface of the display device. Moreover, since the light-emitting display section 2 of the light-emitting body 1 is projected forward from the light projection opening 4 of the container 3, the light output is increased and the display surface becomes brighter, making it easier to see.
