要約(日本語): The arc lighting to obtain the environment to evacuate, save the life, keep the safety and be comfortable are focus on. The lack of radiation intensity and color rendering spectrum is problem because of inappropriate energy balance. This paper elucidates the improvement of color rendering spectrum with control of spectrum affected by metal vapor mixed with high temperature arc. The temperature with keeping the color rendering increases with increasing the contamination ratio of metal vapor because of xy coordinate in chromaticity diagram. In addition, the volume increment of low temperature region; periphery of the arc is effective for the color rendering. The radiation power increases with increasing the metal vapor even if the temperature is low. Especially, the maximum radiation power with metal vapor is 10 times as high as that without one. The radiation power increases with keeping the color rendering and the radiation power increases when the appropriate temperature is chosen under consideration of xy coordinate in chromaticity diagram. The improvement of color rendering spectrum is expected by the control of balance between the broad continuous spectrum of argon and line spectrum of scandium with temperature distribution derived from current increment and/or arc pinch.
