PURPOSE: An LED cooling device is provided to reduce expenses by extending the lifetime of LED. CONSTITUTION: A peltier element(2), a temperature sensor(6), a heat radiation plate(1) and a cooling fan(7) are used to protect LEDs exposed to the outside. A control circuit operates the peltier element, the temperature sensor, the heat radiation plate and the cooling fan. The peltier element and the temperature sensor, the heat radiation plate and the cooling fan prevent the damage of the LEDs due to high temperature. The peltier element has different shapes and sizes. |
