Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a portable electric light having a built-in dry battery and capable of switching a light for lighting a miniature bulb, a torch lamp, and a signal warning light.

[0002]

[Prior art]

 Conventionally, portable electric lamps that use a dry battery as a power source and light a miniature bulb are mainly used not only for lighting, but also for warning signals and warnings with red rays through a red filter or red cover for signals and alarms. It is also used as a signal light for sending cues, and a dual-purpose type that has both functions and can be used for switching is also widely used.

[0003]

[Problems to be solved by the device]

 However, the light passing through a red filter or red cover such as a conventional signal light is dim and has low brightness, and it is difficult to confirm from a distance, which often obstructs emergency warning or signal emergency measures. If you use the dedicated type for each, you have to carry and use each separately, and even if it is the dual type, not only is it complicated to handle because it requires replacement and switching of the cover during lighting, but the lighting structure is complicated. There was a drawback. In particular, we often carry red flags and signal lights to carry out security work for maintenance, security, and inspection work such as railroad or road construction, night train protection, railroad crossing, and monitoring of aisles by workers. It was a problem. The present invention is intended to eliminate these drawbacks of the related art, can simplify the work of selectively using lighting, signals, and alarms, and can increase the brightness of signal and alarm rays, making it easy and suitable for confirmation from a distance. The purpose of the present invention is to provide a portable electric lamp that is reliable, has improved safety, and is extremely easy to handle in a low-cost mobile phone.

According to the present invention, a lighting bulb 3 is provided at the center of a reflector portion 2 which is detachably fitted to a housing 1 of a lamp body, and a red light is provided on an outer peripheral edge portion of the reflector portion 2. A plurality of light emitting diodes 4 that emit light rays are arranged on a concentric circle, and the lighting bulb 3 and the light emitting diodes 4 are turned on or intermittently emitted by a changeover switch 7.

[0005]

[Action]

 The lighting bulb provided in the light-projecting section of the lamp body and the light-emitting diode that emits red light are connected to an electric circuit powered by a dry battery, and the changeover switch is turned on and off to turn on the lighting bulb. Alternatively, it can be safely used as a signal for lighting, a signal, or an alarm by causing a current to flow in any segment of the light emitting diode and turning on or blinking the light.
