  However, since the LED is used in the lamp body in the headlamp described in Patent Document 5, even if a plurality of LEDs are used, the illumination range is narrow due to the directivity of the LED light, and the user is wide. In order to see the range, it is necessary to turn the head itself, which is not only very troublesome but also difficult to work with.

  In view of such problems, it is an object of the present invention to provide a headlamp that is mounted on a helmet and can be illuminated over a wide range.

  Therefore, the headlamp according to the present invention is composed of a mount, a lamp body, and an elastic belt, and the headlamp is mounted on the outer periphery of the shell shell of the helmet. An impact absorbing member is provided on the back surface, a mounting base is formed on the front surface of the mount, and the lamp body is in the range of 1/8 to 1/4 of the shell circumferential length in the circumferential direction of the helmet. The mounting bracket is formed on the back surface of the mounting base, and the mounting bracket is rotatable between a first position directed horizontally toward the mounting base and a second position directed obliquely downward. In addition, the lamp body is connected by a connecting pin so as to hold the rotation position, and a light emitting module that extends in the length direction of the lamp body and emits light is built in the lamp body. The light emitting module has a strip shape, the front surface of the lamp body is sealed with a transparent or translucent light transmitting body, the stretch belt is attached to the mount, and the mount is attached to the helmet by the stretch belt. It is designed to be attached to the outer surface of the shell.

  One of the features of the present invention is a light emitting module that emits surface light by extending in the length direction to a lamp body having a length in the range of 1/8 to 1/4 of the circumferential length of the shell in the circumferential direction of the helmet. The lamp body is attached to the shell of the helmet.

  Accordingly, the user can illuminate over a wide range in front of the helmet without turning his / her head, and at the same time, the wide range can be seen, so that work is easy.

  The second feature of the present invention is that a mounting bracket projects from the rear surface of the lamp body, a mounting base projects from the front surface of the mount, the mounting bracket serves as the mounting base, and the lamp body faces the horizontal front. It is in the point which attached so that rotation was possible and the rotation position was hold | maintained between the 2nd position which orient | assigns diagonally downward.

  As a result, when the lamp body is rotated from the first position to the second position directed obliquely downward, the lower part can be illuminated without the user having to turn the head greatly downward. You can work in an easy posture coupled with the lighting.

  In addition, the mounting bracket protrudes backward, the mounting base protrudes forward, and both are pivotally connected to each other, so that the mounting bracket can be rotated around the position of the connecting pin on the mounting base. Even if the headlamp according to the present invention is used for a helmet with a hook, the light of the lamp body can be directed obliquely downward with almost no obstruction by the hook.

  The lamp body may have a shape that extends straight in the lateral direction, but it may have an arc shape so that light is irradiated over a wider range. That is, it is preferable to use an arc-shaped hollow housing for the lamp body and to manufacture the light emitting module in an arc-shaped band plate shape corresponding to the arc-shaped band of the hollow housing. In particular, when the lamp body is manufactured to have a length of about 1/8 of the circumferential length of the shell, the lamp body can be illuminated in a wide area, although it is a short lamp body, when the lamp body is formed into an arc belt shape.

  The light emitting module only needs to be capable of surface emission. For example, a plurality of light emitting elements are mounted side by side on a substrate, a light guide layer is formed to cover the plurality of light emitting elements, and phosphors are dispersed in the light guide layer. Therefore, it can be configured to emit surface light.

  The power source of the light emitting module may be hung on the waist belt by the user, for example, but it is preferable that the light emitting module can be attached to the helmet by being attached to the elastic belt. That is, the light emitting module is provided so as to be energized and light-emitted by a power source, and the power source is configured by incorporating the power source module in a thin box-shaped housing, and the power source can be configured to be attached to the elastic belt. .

  If the elastic belt is made of silicon rubber, chloroprene rubber or natural rubber, and the rubber surface of the belt is held in close contact with the shell outer surface of the helmet, the elastic belt will not slide on the shell outer surface and the helmet will be stable. Can be attached to.
