Abstract
There is provided a signaling apparatus including a plurality of LED elements provided in a signal lamp body; a transparent panel provided in the LED elements and configured to transmit outgoing light from the LED elements on a rear side to a front surface to which snow adheres; a frame unit provided on an outer periphery of the panel; and vibration generators provided in the frame unit and configured to vibrate the panel.
Claims18
A signaling apparatus with snow adhesion preventing device comprising:
- a first lamp comprising:
- a first transparent panel configured to transmit outgoing light from a plurality of first LED elements on a rear side to a front surface of the first transparent panel to which snow adheres;
- a first frame unit provided on an outer periphery of the first transparent panel;
- and
- first vibration generators provided in the first frame unit and configured to vibrate the first transparent panel;
- at least a second lamp comprising:
- a second transparent panel configured to transmit outgoing light from a plurality of second LED elements on a rear side to a front surface of the second transparent panel to which snow adheres;
- a second frame unit provided on an outer periphery of the second transparent panel;
- and
- second vibration generators provided in the second frame unit and configured to vibrate the second transparent panel;
- wherein the first vibration generators are fixed equiangularly in a circumferential direction to the first frame unit, and wherein the second vibration generators are fixed equiangularly in a circumferential direction to the second frame unit.
