Also provided are sunglasses and goggles equipped with the optical characteristics adjusting system.

Abstract: Provided is a method of warning of an abnormal state of an air purifier of a respirator, in which when an abnormality of the air purifier occurs, colors, flickering intervals, and display patterns of light emitting diodes (LEDs) are differently output in such a way that an abnormal state such as a dead battery of the air purifier which purifies polluted external air and supplies the purified air to a worker, an error caused by a blockage of a filter unit due to foreign substances, an abnormality in a load rate of the filter unit, and an error, abnormality, failure and danger caused by the expiration of an operation time and a replacement of the filter unit is warned and at the same time informed to other workers who are working near the worker to prevent a dangerous situation in which the polluted external air which is not filtered and purified is inhaled by the worker through the respirator.

Abstract: Provided is a method of recognizing information on a filter unit mounted on an air purifier of a respirator wherein the air purifier and the filter unit of the respirator which filters polluted external air and supplies purified air to a worker are wirelessly interconnected such that a control unit of the air purifier may provide the worker with information on the filter unit such as a type, a load rate depending on a blockage degree of the filter unit, a final operation time, a residual operation time, and a replacement time of the filter unit through information data transmitted from the filter unit. It is possible to precisely recognize the filter unit appropriate for a workplace and a work environment, thereby preventing an error, failure, and malfunction of the filter unit and simultaneously with continuously working.

Abstract: An information display and control device of an air purifying respirator comprises: a blower motor; a pulse width modulation drive unit controlling rotation of the blower motor; a temperature sensor; an air flow sensor; an oxygen sensor; a voltage detection unit for a battery; a differential pressure sensor detecting a differential pressure value of a filter; a switch input unit for a user to input predetermined temperature, air flow, and oxygen amount and operation commands; a controller executing a diagnostic mode, calibrating the oxygen sensor, calculating a detected value of the voltage detection unit to determine whether the voltage is low, comparing the detected value of the differential pressure sensor with a reference to determine whether the filter is absent or clogged, and comparing the detected value of the oxygen sensor with a reference to determine whether oxygen is insufficient or excessive; and an alarm output unit outputting an alarm.

Abstract: Disclosed herein is a welding helmet in which a worker may transmit and block external light as necessary by forming a light switching window for blocking external light from a side surface of the welding helmet (helmet). The welding helmet equipped with a light switching window, which includes a helmet body portion which protects the worker's face and a cartridge which blocks harmful light generated during welding to protect the worker's eyes, includes a light switching window formed on a side surface of the helmet body portion such that external light is transmitted or blocked by the light switching window. The light switching window has a structure in which it may be possible to identify risk factors around a work area and a worker may block unnecessary light as necessary. Particularly, since an operating radius is enlarged, it may be possible to provide the worker with convenience.
