PURPOSE:To reduce eye fatigue by using a light source which radiates light which substantially does not delay the emergence and immergence time of a specific wave, at human vision evoked potential(VEP). CONSTITUTION:Using an incandescent lamp charged with xenon gas, which contains composition 7 of approximately 75voume% xenon gas and approximately 25volume% nitrogen gas for charge in an incandescent lamp inside the glass bulb 1 and the composition 7 becomes approximately 600Torr at a room temperature and approximately 760Torr at lighting, as a light source, the delay at the time of output immergence of a P100 wave in the VEP of a person will become approximately 5% at work for 120 minutes or the like. By the radiation that the time of emergence and immergence of tis P100 wave does not substantially delay, eye fatigue is difficult to be caused. |
