Abstract
In a color changing lamp equipped with a bulb 4 emitting a color of light, a glove with a different color from the color is selectively located on the covering position and exposure position of the bulb 4 in order to emit the different color of light. The current supply for the bulb 4 is stopped while the glove is selectively moved, thereby preventing different colors of light in a mixed state from being emitted on the way of exchange.
