Apparatus for detecting welding light and protecting eyes from glare and method for controlling the same
A welding light detection and anti-glare eye protection apparatus, which shields welding light generated in welding or cutting environments to safely protect eyes of a worker from the welding light, and a method for controlling the same are provided. When the apparatus is powered on, it is determined, based on a reference value, whether or not a specific time has passed without detecting welding light. If the specific time has passed without detecting welding light, a power saving mode is performed. If welding light is detected while the power saving mode is performed, normal power is supplied and light transmittance is controlled. When the power saving mode is performed, the reference value is reset so that photosensitivity is reduced below a specific value. This method saves energy while preventing the apparatus from operating abnormally. Thus, it is possible to drive the anti-glare eye protection plate most efficiently according to ambient environments.
1. A method for controlling an apparatus for detecting welding light and protecting eyes from glare, the apparatus including an anti-glare eye protection plate for protecting eyes of a worker from light generated by a welding or cutting torch, the method comprising:
determining, when the apparatus is powered on, whether a specific time has passed without detecting welding light, based on a reference value;
performing a power saving mode if the specific time has passed without detecting the welding light; and
supplying normal power and controlling light transmittance of the anti-glare eye protection plate if the welding light has been detected while the power saving mode is performed,
wherein, when the power saving mode is performed, the reference value is reset so that photosensitivity is reduced below a specific value.
