To provide an LED type traffic signal snow accretion preventing cover capable of preventing snow accretion on a display unit of an LED type traffic signal light device display unit with low power and enhancing visibility of the display unit.SOLUTION: An LED type traffic signal snow accretion preventing cover 10 is mounted on a display unit 20a of an LED type traffic signal light device 20, comprising: a circular snow accretion prevention cover body 12; a circular elastic member 14 for fixing the snow accretion preventing cover main body 12 by concentrically overlapping it and whose diameter is larger than that of the snow accretion preventing cover body 12; and a cylindrical mounting member 16 for fixing the elastic member 14 and having the same diameter as that of the elastic member 14. A hole 14a concentric with an outer edge of the elastic member 14 having a diameter smaller than that of the snow accretion preventing cover body 12 penetrating the elastic member 14 is provided with the elastic member 14. A vibration generating device 18 for providing impact and vibrating the snow accretion prevention cover body 12 is provided. Thus, snow accretion of the snow accretion preventing cover body 12 is removed with small power, and visibility of the display unit 20a of the LED type traffic signal light device 20 can be secured.SELECTED DRAWING: Figure 1
【課題】少電力でLED式交通信号灯器表示部の表示部の着雪を防止し及び表示部の視認性を高めることができるLED式交通信号着雪防止カバーを提供する。【解決手段】LED式交通信号着雪防止カバー10は、LED式交通信号灯器20の表示部20aに取り付けるものであり、円形の着雪防止カバー本体12と、着雪防止カバー本体12を同心円状に重ね合わせて固定する、着雪防止カバー本体12より径大の円形の弾性部材14と、弾性部材14を固定する、弾性部材14と同径の円筒状の取付部材16とを備える。弾性部材14に弾性部材14を貫通する着雪防止カバー本体12より径小の弾性部材14の外縁と同心円の穴14aを設け、着雪防止カバー本体12に衝撃を与えて振動させる振動発生装置18を設ける。これにより、小電力で着雪防止カバー本体12の着雪を取り除き、LED式交通信号灯器20の表示部20aの視認性を確保できる。【選択図】図1
