Abstract
A laser light source module includes a plurality of unit laser light source modules, each of which emits laser light of one specific color, and when the laser light source module includes unit laser light source modules of at least two colors, and each unit laser light source module has a median of a temperature range in which a practical luminance is obtained, the unit laser light source modules are thermally connected to an evaporator and arrayed in descending sequence of their values of the median from an upstream side in a direction in which a refrigerant flows.
