Document Type and Number:
Japanese Patent JP3320863
Kind Code:
B2
Abstract:
PURPOSE:To keep a synthetic color temperature at a desired temperature as long as possible even when any error is generated in the quantity of emitted stroboscopic light by detecting the color temperature of surrounding light and controlling the color temperature of the stroboscopic light with two pairs of required color temperature control means. CONSTITUTION:The color temperature of surrounding light is detected by a color measuring sensor 22, and a voltage to be impressed to a guest host type blue system liquid crystal filter 52 and an amber system liquid crystal filter 53 arranged in front of a xenon tube 51 for emitting the stroboscopic light is controlled by a control circuit 23 and a color liquid crystal control circuit 54. When the color temperature of the surrounding light is higher than a color temperature K2 peculiar for the stroboscopic light, the filter 53 is made transparent and when the color temperature is lower, the filter 52 is made transparent. Thus, even when the error is generated in the quantity of emitted stroboscopic light, the synthetic light temperature of synthetic stroboscopic light F can be controlled at the desired temperature as much as possible.
