Example of helmet mounted lighting

1 and 2 is a schematic view showing the structure of a helmet mounted lighting device according to an embodiment of the present invention.

As shown in Figure 1 and 2, the helmet-mounted lighting device 100 according to an embodiment of the present invention is a component mounted on the helmet sunshade 170, the blanket unit 110, the bracket fixing lever 120, the lighting device mounting unit 130, the irradiation angle adjusting unit 140, the lighting device unit 150, and the push switch unit 160 may be included. The components will be arbitrarily described regardless of the order of the reference numerals.

The bracket unit 110 according to the present invention is mounted on the helmet hat 170, the helmet hat 170 is inserted in the middle, and in the inserted state, the upper and lower structures of the bracket fixing lever ( By fixing using 120, the helmet is conveniently and quickly mounted to the sunshade 170. At this time, the bracket fixing lever 120 of the present invention, which is a fixing means of the bracket unit 110, is designed in a lever (Lever) type that can be pulled up and down and pulled out, and because of this lever type, no tools are required. The helmet unit can be easily detached and attached to the blanket unit 110 in a state wearing an insulating protective gloves 170.

Illumination device mounting unit 130 according to the present invention is made of a structure including a depression 131 recessed in the center of one side in the opposite direction of the hard hat facing, is formed on the blanket unit 110, the Can be fastened by coupling with the blanket unit 110. The recess 131 may be equipped with a lighting device unit 150 to be described later, it is made of a structure of a size corresponding to the lighting device unit 150, to mount the lighting device unit 150.

The irradiation angle adjusting unit 140 according to the present invention is mounted on the lower portion of the lighting device mounting unit 130 and serves to adjust the lighting device mounting unit 130 up and down in the front direction of the helmet. Due to mounting on the lower portion of the device mounting unit 130, it is possible to maintain the state combined with the blanket unit 110, in this state to freely move the lighting device mounting unit 130 in the front direction of the helmet. By controlling the movement of the lighting device mounting unit 130 is to be adjusted.

The lighting device unit 150 according to the present invention is inserted into the recess 131 of the lighting device mounting unit 130 and is mounted in the form of a mag (MAG) to the lighting device mounting unit 130, the lighting device mounting unit ( Due to the up and down movement of 130, it is possible to perform the role of illuminating the light by the up and down movement range. The lighting device unit 150 may be illuminated by the irradiation angle of 60 to 120 ° up, down, left, and right at the right time of the helmet wearer due to the vertical movement of the lighting device mounting unit 130, but is not necessarily limited thereto.
