Document Type and Number:
Japanese Patent JP6642792
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a marker lamp capable of preventing power input from being blocked undesirably by an impact force to a lamp body.SOLUTION: A lamp body 5 stores an LED 20 and a lightning circuit 18 for performing lighting control of the LED 20 by inputting an AC constant current power supply, and has a light emission port 13 from which radiation light of the LED 20 is emitted. An opening/closing device 6 includes: a mechanical contact point part for opening/closing electric connection between the AC constant current power supply and the lightning circuit 18; and a contact point opening/closing mechanism for closing the electric connection by pressing the contact point part and maintaining the closed state, and for opening the electric connection by the release of pressing. Lighting state detection means monitors a lighting state of the LED 20, and controls the contact point opening/closing mechanism so that the contact point part opens according to the lighting state. A mounting device 61 has a mounting member 63 which supports the opening/closing device 6 and which can elastically deform so that the supported opening/closing device 6 moves. By the mounting member 63, the opening/closing device 6 is mounted in the lamp body 5.SELECTED DRAWING: Figure 2
