Abstract

A cooling device of high intensity gas discharge lamp includes a flow-guide element and a flow generation device, wherein the flow-guide element has a recessed portion and an air vent, and the recessed portion is used to accommodate a neck of a reflector. After cooling air flow generated by the flow generation device passes through the air vent, it can flow through a gap between a discharge lamp and the neck of the reflector to generate a cooling effect on a discharge region and the neck of the reflector, and hot air eventually flows through an air gap between the reflector and a front light cover glass to be exhausted. Alternatively, cooling air absorbed by the flow generation device passes through the gap between the reflector and the front light cover glass to generate a cooling effect on the discharge region and the neck of the reflector, and hot air eventually flows through the gap between the discharge lamp and the neck of the reflector and passes through the air vent to be exhausted. The cooling air generated by blowing air or absorbing air can maintain the discharge region of the reflector and the discharge lamp at an optimal operating temperature so as to enhance light emission rate and prolong operational lifespan.
