Description

  The present invention relates to a helmet with an illuminating device, and particularly relates to a helmet equipped with an illuminating device that can secure a light and wide field of view.

  There is a headlight that can be mounted on a helmet as a lighting device used when performing a work performed by wearing a helmet, such as construction work, security, inspection, etc. in a dark place. Such a headlight has the advantage that both hands can be used freely, unlike a lighting fixture that is used in the hand.

  However, since such a headlight is mounted on the outside of the helmet, the workability in a narrow place may be deteriorated when the headlight collides with the surroundings. In addition, the headlight may hit the surroundings and be damaged. Further, in such a headlight, since a light bulb is generally used as a light source, there is a problem that a large amount of power is consumed.

Conventional techniques for attaching a light emitting diode to a helmet include (Patent Document 1) (Patent Document 2), (Patent Document 3), and (Patent Document 4).
Patent Document 1 describes a case where an LED is attached as a light emitter on the outside of a helmet. Patent Document 2 describes that an LED light emitter is disposed on the outer peripheral surface of an attachment main body that is clamped and fixed to the outer peripheral edge of the helmet. Patent Document 3 describes an LED on the surface of the helmet. A device in which a plurality of elements are mounted is described.

  However, the techniques described in Patent Document 1 to Patent Document 3 are intended to inform a third party or the like of their location in a dark place. For this reason, the light from a plurality of attached LEDs is irradiated in different directions. Therefore, the techniques described in Patent Document 1 to Patent Document 3 cannot efficiently use the light from the light emitter as illumination for work in a dark place.

Patent Document 4 describes a helmet in which an LED is attached to a socket part provided at a tip part of a heel part.
However, since the technique described in Patent Document 4 is for confirming the presence or absence of a voltage in the charging unit, the LED lights up when the worker approaches a live wire, and is used for work in a dark place. It cannot be used as lighting.
