Document Type and Number:
Japanese Patent JP2017185707
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a luminescent device capable of shortening a period required to stabilize a temperature of luminescent element after the same is lit.SOLUTION: A luminescent device comprises: a luminescent element which emits light: a cooling body which cools the luminescent element; and a control unit which controls in a manner that stabilizes at least either electric current or electric voltage of the luminescent element and controls a cooling amount of the cooling body to cool the luminescent element. When the luminescent element is lit, the control unit controls in a manner that stabilizes the cooling amount after stabilizing at least either the electric current or the electric voltage of the luminescent element.SELECTED DRAWING: Figure 4
