Abstract

When using, an entire length from a grip portion to a light emitting lamp portion is elongated by drawing out the light emitting lamp portion from the grip portion so as to extend, and each of light emitting diodes in the light emitting lamp portion is turned so as to be usable by operating a main switch button in an infrared remote control sending apparatus. Further, a worker arranged at one point in a vehicle guiding section switches a color of emitted light of the light emitting lamp portion in a portable signal light, whereby the emitted light is switched to a blue “GO” display allowing a vehicle to move forward or a red “STOP” display inhibiting the vehicle from moving forward. Accordingly, it is possible to safely and smoothly guide the vehicle only by one worker.

Claims

1. A portable signal light, wherein the portable signal light is provided with a tubular light emitting lamp portion which is telescopically fitted to a tubular grip portion, the light emitting lamp portion has a battery for a power source and a plurality of light emitting diodes which can be turned on by the battery built-in, said grip portion is provided with an infrared remote control sending apparatus for controlling the lighting of said light emitting diode, and said light emitting lamp portion is provided with an infrared remote control receiving apparatus for receiving the control signal from said infrared remote control sending apparatus so as to control the lighting of said light emitting diode.

3. A portable signal light as claimed in claim 1 or 2, wherein said infrared remote control sending apparatus is detachably provided in said grip portion.

2. A portable signal light, wherein the portable signal light is provided with a tubular or bar-like support portion which is telescopically fitted to the tubular grip portion, and the support portion is provided with the light emitting lamp portion which has a battery for a power source and a plurality of light emitting diodes which can be turned on by the battery built-in, said grip portion is provided with the infrared remote control sensing apparatus for controlling the lighting of said light emitting diode, and said light emitting lamp portion is provided with the infrared remote control receiving apparatus for receiving the control signal from said infrared remote control sending apparatus so as to control the lighting of said light emitting diode.

4. A portable signal light as claimed in claim 2, wherein the light emitting lamp portion is detachably mounted to the support portion.
