PROBLEM TO BE SOLVED: To provide a light emitter cover that can effectively prevent snow from accreting to a signal lighting unit and the like formed by an LED light emitter of a traffic light, and a signal lighting unit comprising the light emitter cover.SOLUTION: A light emitter cover 10 includes a light transmissive convex dome section 10A covering the front side of a light emitter, and a curved surface 23 facing front downward from an eaves-like upper front end section 21A of the convex dome section toward a lower front section 22 of the convex dome section. The light emitter cover is attached so as to individually cover the entire front section of a lighting unit and the like of a traffic light 41, for example, especially LED light emitters 12A, 12B and 12C of green, yellow and red.SELECTED DRAWING: Figure 1
【課題】交通信号機のLED発光器で形成された信号用灯器等における着雪を効果的に防止できる発光器用カバー、および当該発光器用カバーを備えた信号用灯器を提供する。【解決手段】発光器用カバー10は、発光器の正面側を覆う透光性の凸状ドーム部10Aを有し、当該凸状ドーム部の庇状の上部前端部21Aから凸状ドーム部の下部前面部22に向かって前側下方に面した湾曲面23を有するように構成される。この発光器用カバーは、交通信号機41の灯器等、例えば特に青、黄、赤の各LED発光器12A,12B,12Cの正面部の全体を個別に覆うように取り付けられる。【選択図】図1
