Document Type and Number:
Japanese Patent JP2014240981
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a marker lamp in which the thickness of the lamp can be restricted by a simple structure, light is allowed to pass through and emit from a display part to make information displayed on the display part become easily recognized from outside, and external light irradiated from outside can be reflected in a direction from which the external light is irradiated.SOLUTION: The present invention comprises: a light source part which emits light; a light-guiding part which is adjacent to the light source part and emits light made incident to a side face from a principal surface; a transmission and reflection part which is laminated on one principal surface of the light-guiding part, allows a part of light emitted from one principal surface of the light-guiding part to pass through, and reflects external light irradiated from outside; and a display part which is laminated on the transmission and reflection part, on which predetermined information is displayed, and which allows light from the transmission and reflection part to pass through. In the light-guiding part, dot state recesses are formed at least one surface of one principal surface or another principal surface in a matrix state. The transmission and reflection part consists of reflection parts on which a triangular pyramid-shaped recessed-shaped reflective film is formed and a transmission part provided between the reflection part and the reflection part.
