PROBLEM TO BE SOLVED: To deal with such a problem, by increasing the degree of freedom in designing a cooling structure and realizing a still more preferable cooling structure, that which structure should be used to dissipate heat in circumstances in which, for example, it is made possible to make the direction of heat dissipation and the direction of illumination the same and LEDs have been begun to be used as headlights of a vehicle, and heat dissipation processing must be performed inside of the headlight because it is not permitted to let heat escape into a vehicle body in future vehicles but such a space is limited.SOLUTION: The cooling system is characterized by including a case having a space inside thereof, an LED attached to the inside of the case, and a cooling liquid which is filled on the front surface side of the LED in the case and has a function to cool heat of the LED that emits light, wherein the cooling liquid is configured by a liquid having an insulation resistance value of 10Ω or more. |
