Abstract
【課題】交通信号灯におけるカバー本体の正面部を改良して、カバー本体に直接太陽光線が当っても信号灯の「色」が目視できるようにし交通安全を確保する交通信号灯を提供する。【解決手段】交通信号灯におけるカバー本体の正面部を正面視が防眩凹曲面であることを特徴とする。運転者或いは歩行者の後方からの太陽光線が信号灯を照射してもカバー本体に当った光線は光束が焦点線上に集束して乱反射を起こさず、運転者、歩行者は容易に信号灯の「色」を目視し確認することができ交通安全を確保できる。【選択図】図１Provided is a traffic signal lamp that improves the front portion of a cover main body in a traffic signal lamp so that the "color" of the signal lamp can be visually observed even when the cover body is directly exposed to sunlight. A front surface of a cover body in a traffic signal lamp has an antiglare concave curved surface when viewed from the front. Even if sunlight from the back of the driver or pedestrian illuminates the signal light, the light beam that hits the cover body is focused on the focal line and does not cause irregular reflection. ”Can be visually confirmed and traffic safety can be ensured.

Description
本考案は、交通信号灯の改良に関する。 The present invention relates to an improvement of a traffic signal lamp.
従来の交通信号灯（自動車用、歩行者用を含む。）の表面カバーは正面視凸面となっている。 The surface cover of conventional traffic signal lights (including those for automobiles and pedestrians) is convex in front view.
殊に車の運転者の後方からの太陽光線が信号灯に当る朝夕等には、太陽光線によって信号灯の「色」が分かり難くなるほど乱反射して、運転者にとって目視困難な状況となり、交通安全を確保できないなどの危険性がある。勿論歩行者用の信号灯にも同じことが言える。 In particular, in the morning and evening when sunlight from behind the car driver hits the signal light, the sunlight causes diffuse reflection so that the “color” of the signal light becomes difficult to understand, making it difficult for the driver to see and ensuring traffic safety. There is a danger of being unable to do so. Of course, the same can be said for signal lights for pedestrians.
そこで本考案では、交通信号灯におけるカバー本体の正面部を改良して、カバー本体に直接太陽光線が当っても信号灯の「色」が目視できるようにし交通安全を確保しようとするものである。 Therefore, the present invention is to improve the front part of the cover body in the traffic signal lamp so that the “color” of the signal lamp can be visually observed even if the cover body is directly exposed to sunlight.
交通信号灯におけるカバー本体の正面部を正面視が防眩凹曲面であることを特徴とする交通信号灯である。 The traffic signal lamp is characterized in that the front portion of the cover body of the traffic signal lamp has an antiglare concave curved surface when viewed from the front.
本考案の効果として、運転者或は歩行者の後方からの太陽光線が信号灯を照射してもカバー本体に当った光線は光束が焦点線上に集束して乱反射を起こさず、運転者、歩行者は容易に信号灯の「色」を目視し確認することができ交通安全を確保できる。 As an effect of the present invention, even if the sun rays from the back of the driver or pedestrian irradiate the signal light, the light that hits the cover body is focused on the focal line and does not cause irregular reflection. Can easily check the "color" of the signal light and ensure traffic safety.
図１において、交通信号灯１におけるカバー本体２の正面部を正面視が粗面状の防眩凹曲面３であることを特徴とするものである。図中４は取付枠、５は本体ケースでＬＥＤ素子６などが取付けられている。７は庇、８はヒートシンク、９はＬＥＤランプである。 In FIG. 1, the front part of the cover main body 2 in the traffic signal lamp 1 is an antiglare concave curved surface 3 whose front view is rough. In the figure, reference numeral 4 denotes an attachment frame, and 5 denotes a main body case on which the LED element 6 and the like are attached. 7 is a bag, 8 is a heat sink, and 9 is an LED lamp.
図２は歩行者用の信号灯であり構造的には上記図１の信号灯と殆ど同じである。 FIG. 2 shows a signal light for pedestrians and is structurally almost the same as the signal light in FIG.
本案は以上のようになるものであるが、運転者或は歩行者の後方からの太陽光線が信号灯を照射してもカバー本体に当った光線は光束が焦点線上に集束して乱反射を起こさず、運転者、歩行者は容易に信号灯の「色」を目視し確認することができる。 Although the present plan is as described above, even if sunlight from the back of the driver or pedestrian illuminates the signal light, the light beam that hits the cover body does not cause irregular reflection because the light beam is focused on the focal line. The driver and the pedestrian can easily visually check the “color” of the signal light.
