（第１の実施の形態の効果）
次に、第１の実施の効果を図５、図６および図７を参照して説明する。
図５および図６は、第１の実施の形態に係る屋外表示器１と特許文献１に対応する表示器についての比較例であり、図５は、斜め上方から見た斜視図、図６は、斜め下方から見た斜視図、図７は、正面から外光が入射したときの反射を示す断面図である。図５および図６は、上側７行を本実施の形態、下段３行を従来例により構成した比較例である。 (Effects of the first embodiment)
Next, the effect of the first embodiment will be described with reference to FIGS.
FIGS. 5 and 6 are comparative examples of the outdoor display 1 according to the first embodiment and the display corresponding to Patent Document 1, FIG. 5 is a perspective view seen from obliquely above, and FIG. FIG. 7 is a cross-sectional view showing reflection when external light is incident from the front. FIGS. 5 and 6 are comparative examples in which the upper seven rows are configured according to the present embodiment, and the lower three rows are configured according to the conventional example.

第１の実施の形態によれば、各ＬＥＤランプ２の上方をルーバ部５ａにより弧状に覆ったので、図５に示すように、下側３行の従来例よりもランプ２の隠れる領域が増えていることから分かるように、斜め上方からの外光がランプに照射してその反射光量が少なくなるので、ＬＥＤランプによる表示の視認性が向上する。   According to the first embodiment, since the upper part of each LED lamp 2 is covered in an arc by the louver portion 5a, the area where the lamp 2 is hidden is increased as compared with the conventional example of the lower three rows as shown in FIG. As can be seen from the above, since the external light from obliquely above is applied to the lamp and the amount of reflected light is reduced, the visibility of the display by the LED lamp is improved.

ルーバ部５ａ間に低背部５ｂを設けたので、近距離から屋外表示器を見上げた場合、図６に示すように、下側３行の従来例よりもランプ２の見える領域が増えていることから分かるように、近距離の視野角を大きくすることができる。   Since the low-profile part 5b is provided between the louver parts 5a, when the outdoor display is looked up from a short distance, as shown in FIG. 6, the area where the lamp 2 can be seen is larger than the conventional example in the lower three rows. As can be seen, the viewing angle at a short distance can be increased.

また、ルーバ部５ａの先端面５ｃは、鉛直に対して傾斜しており、また、外光を乱反射させる処理が施されているため、外光による反射光が視野外に反射するので、ＬＥＤランプの発光光を認識しやすくなる。   Further, the front end surface 5c of the louver portion 5a is inclined with respect to the vertical, and is subjected to a process of irregularly reflecting external light, so that reflected light from the external light is reflected outside the field of view. It becomes easier to recognize the emitted light.

また、ＬＥＤランプ２がルーバ部５ａの内面を明るく照射するため、夜間などにおいて近距離の表示の視認性が向上する。   Moreover, since the LED lamp 2 irradiates the inner surface of the louver part 5a brightly, the visibility of a short distance display is improved at night.

また、図７に示すように、ベース４は、複数の開口４ａの各周辺に斜め下前方に傾斜した傾斜面４ｂを有しているため、外光による入射光１０の反射光１１が視野外に反射するので、ＬＥＤランプの発光光を認識しやすくなる。これに対して、従来の屋外表示器のベース５４に外光による入射光１０が反射して入射方向に戻る方向の反射光１２を出射するので、ＬＥＤランプの発光を認識しにくくなる。   Further, as shown in FIG. 7, the base 4 has inclined surfaces 4b inclined obliquely downward and forward around each of the plurality of openings 4a, so that the reflected light 11 of the incident light 10 by outside light is out of the field of view. The light emitted from the LED lamp can be easily recognized. On the other hand, since the incident light 10 by the external light is reflected on the base 54 of the conventional outdoor display and the reflected light 12 in the direction returning to the incident direction is emitted, it becomes difficult to recognize the light emission of the LED lamp.

［第２の実施の形態］
図８は、本発明の第２の実施に形態に係る屋外表示器のルーバを示す。このルーバ５は、低背部５ｂを有し、正面側から見たときは、平板状である。このルーバ５によれば、低背部を有するため、視野角を大きくすることができ、これにより広い範囲で表示を視認することができる。 [Second Embodiment]
FIG. 8 shows a louver for an outdoor display device according to a second embodiment of the present invention. The louver 5 has a low-profile portion 5b, and has a flat plate shape when viewed from the front side. According to this louver 5, since it has a low-profile part, the viewing angle can be increased, and thus the display can be viewed in a wide range.

［他の実施の形態］
なお、本発明は、上記各実施例に限定されず、その要旨を変更しない範囲内で種々変更してもよい。例えば、複数のＬＥＤランプは、単色に限らず、２色以上のものを組み合わせてもよい。また、１つのＬＥＤランプの中に同じ色または異なる色の複数のＬＥＤ素子を含むものであってもよい。また、ベースの開口以外の面に穴をあけることにより、外光の反射を抑えることができる。また、ルーバ部は、上面あるいは正面から見たときに円形状、三角形状、台形状等の他の形状であってもよい。これによれば、横方向からの外光があってもＬＥＤランプの発光を視認することができ、視野角を大きくとることができる。 [Other embodiments]
In addition, this invention is not limited to said each Example, You may change variously within the range which does not change the summary. For example, the plurality of LED lamps is not limited to a single color, and may be a combination of two or more colors. One LED lamp may include a plurality of LED elements of the same color or different colors. Moreover, reflection of external light can be suppressed by making a hole in a surface other than the opening of the base. Further, the louver portion may have other shapes such as a circular shape, a triangular shape, and a trapezoidal shape when viewed from the upper surface or the front surface. According to this, even if there is external light from the lateral direction, the light emission of the LED lamp can be visually recognized, and the viewing angle can be increased.
