Abstract: A welding mask with a sensor lamp provides a welding protector. The welding mask with the sensor lamp includes a mask shell covering a human face, a filter module arranged on the mask shell, a head lamp arranged on the filter module, and a control switch connected to the cord of the head lamp, and the control switch comprises a mechanical switch and a sensing module; the head lamp is provided on the filter module according to the present disclosure, so that lighting will be provided for operator in poor lighting environment, then the welding quality can be guaranteed; the mechanical switch and the sensing module, and the mechanical switch has a plurality of gear selections, whereby selection in relation to normally-on, normally-off and sensor circuit is achieved, which boasts higher security.

Abstract: The disclosure provides a protective visor applicable to multiple operation environments for dust prevention, anti-shock glasses, chemical defense and ray radiation protection. The protective visor comprises a headband, a face shield, protective goggles, a light shading screen, a light grid and a housing, which are connected to each other. The light shading screen and the light grid constitute a light refraction and transmission device for refracting and transmitting the light, which includes a light aperture processed to have a curved surface and located at the front and upper end portion of the housing. The light aperture has a serrated lattice shutter structure, and the light shading screen is disposed at the outer side of the light aperture. The protective visor can effectively prevent foreign splash, and absorb radiant heat and certain ultraviolet rays to protect an operator's face.
