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, comprising:

a tubular light emitting lamp portion which is telescopically fitted to a tubular grip portion, the light emitting lamp portion defines a housing containing a battery for a power source and a plurality of light emitting diodes which can be turned on by the battery, said grip portion is provided with an infrared remote control sending apparatus operative for controlling the lighting of said plurality of light emitting diodes, and said light emitting lamp portion is provided with an infrared remote control receiving apparatus operative for receiving the control signal from said infrared remote control sending apparatus so as to control the lighting of said plurality of light emitting diodes,

a main switch device mounted to the grip portion and operative to cause the infrared remote control sending apparatus to send an infrared signal to the remote control receiving apparatus to cause the plurality of light emitting diodes to either turn on or turn off, and

a change switch device mounted to the grip portion and operative to switch the turn-on plurality of light emitting diodes between a continuous lighting state and a flashing lighting state.

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.

5. A portable signal light as claimed in claims 1 or 4, further comprising a receiving case connected to the grip portion, the receiving case sized to receive the main switch device and the change switch device.

6. A portable signal light as claimed in claim 5, wherein the receiving case has an infrared light sending window and houses the infrared remote control sending apparatus therein.

7. A portable signal light as claimed in claims 1 or 2, wherein the light emitting lamp portion includes a head disposed at a distal end of the light emitting lamp portion, the head having an infrared light receiving window and housing the infrared remote control receiving apparatus therein.

2. A portable signal light, comprising:

a tubular or bar-like support portion which is telescopically fitted to a tubular grip portion, and the support portion is provided with a light emitting lamp portion defining a housing containing a battery for a power source and a plurality of light emitting diodes which can be turned on by the battery, said grip portion is provided with an infrared remote control sending apparatus operative for controlling the lighting of said plurality of light emitting diodes, and said light emitting lamp portion is provided with the infrared remote control receiving apparatus operative for receiving the control signal from said infrared remote control sending apparatus so as to control the lighting of said plurality of light emitting diodes,

wherein the light emitting lamp portion is detachably mounted to the support portion.

4. A portable signal light comprising:

a portable signal light is provided with a tubular or bar-like support portion which is telescopically fitted to a tubular grip portion, and the support portion is provided with a light emitting lamp portion defining a housing containing a battery for a power source and a plurality of light emitting diodes which can be turned on by the battery, said grip portion is provided with an infrared remote control sending apparatus operative for controlling the lighting of said plurality of light emitting diodes, and said light emitting lamp portion is provided with the infrared remote control receiving apparatus operative for receiving the control signal from said infrared remote control sending apparatus so as to control the lighting of said plurality of light emitting diodes,

a main switch device mounted to the grip portion and operative to cause the infrared remote control sending apparatus to send an infrared signal to the remote control receiving apparatus to cause the plurality of light emitting diodes to either turn on or turn off, and

a change switch device mounted to the grip portion and operative to switch the turn-on plurality of light emitting diodes between a continuous lighting state and a flashing lighting state.
