PROBLEM TO BE SOLVED: To put into practical use a signal light device that is for low power consumption measures and is at low cost due to an optical semiconductor, and to provide a signal light comprising an optical semiconductor that emits three color lights only by a light, is low power consuming and is at low cost, the signal light preventing snow accretion on a traffic signal device installed in a snowy district.SOLUTION: In a signal light device, a double-faced mirror 6 rotated by a motor 3 is disposed at a focal point of a concave reflection mirror 4, an LED element unit 5 is embedded at a place adjacent to the inside of the concave reflection mirror, the optical axis of the LED element unit is provided so as to be positioned in the rotation axis 7 direction of the double-faced mirror, the radiant light of the LED element unit is subjected to sweep irradiation at 360 degrees in the horizontal direction by rotation of the double-faced mirror, and light is radiantly output onto a translucent panel 8.EFFECT: A conventional traffic signal device normally comprises three lights horizontally aligned, and hence snow tends to accumulate on eaves in snow and measures against snow damage are necessary, while the signal light device displays three colors by a light, hardly causing snow accretion.SELECTED DRAWING: Figure 1
【課題】低消費電力対策、光半導体による低価格の信号灯器の実用化を図る。1灯だけで3色を発光する低消費電力で低価格の光半導体による、雪国に設置する交通信号器の着雪を防止する信号灯を提供する。【解決手段】凹面反射鏡4の焦点にモーター3により回転する両面反射鏡6を構成し、凹面反射鏡の内側の近接した場所にLED素子ユニット5を埋設し、LED素子ユニットの光軸が両面反射鏡の回転軸7方向に位置するように配設し、LED素子ユニットの放射光を両面反射鏡の回転によって水平方向に360度に掃引照射し、透光性パネル8に光を放射出力する。【効果】従来の交通信号器は通常3灯を水平に並べて設置しているので、降雪によって庇に雪が積もりやすく、雪害対策が必要であるが、1灯による3色表示をするので、積雪が起こりにくい。【選択図】図1
