Claim 0:
1. A welding information providing apparatus comprising:
an automatic light-shielding cartridge;
a main body provided to be worn by a user;
a display unit that is configured to display a welding image to the user, wherein the display unit is configured to be arranged on the main body and, wherein the display unit comprises a portion facing the user;
at least one camera unit configured to face an outside front of the main body and obtain the welding image frame for welding work wherein the at least one camera unit is included in a front portion of the display unit and wherein the at least one camera unit has a structure in which the automatic light-shielding cartridge is located in front of a lens of the camera unit receiving light from a subject;
a sensor unit arranged outside the main body and comprising a module configured to detect light intensity at least within a welding area;
an environmental management unit configured to face the outside of the main body and to obtain changing information about a welding environment; and a processor provided to operatively communicate with the display unit, the at least one camera unit, the sensor unit, and the environmental management unit, and to provide the welding image frame obtained by the at least one camera unit toward a portion facing the user of the display unit,
wherein the processor changes a light-shielding degree of the automatic light-shielding cartridge based on the sensing information about the intensity of welding light obtained through the sensor unit;
wherein the environmental management unit includes environmental sensing modules located on both sides and a rear surface of the main body, wherein the environmental sensing modules are camera modules;
wherein an environmental sensing area is formed by each of the environmental sensing modules, such that the environmental sensing areas are at both sides and a rear area of the user;
wherein the display unit provides a main screen to the user, wherein the main screen comprises the welding image frame captured with respect to a welding imaging area and wherein an environment display area is located in one area of the main screen and wherein environment images from the environmental sensing modules are displayed on the environment display area;
wherein the environmental management unit also includes a switching unit located outside of the main body and electrically connected to the processor, such that the switching unit is configured to be capable of: simultaneously switching off all the environmental sensing modules in one operation, and sequentially switching off the environmental sensing modules on both sides and the rear surface of the main body in turn.
