Abstract
A fiber optic light source having an improved cooling scheme for preventing heat damage to the fiber optic cable input ends. The housing for the light source is divided into two sections, with a separate cooling air supply for each section. The first section is provided with a high volume cooling air flow for general area cooling of the lamp assembly, power supply and other exothermic components. The second section is provided with a high velocity cooling air flow directed at the fiber ends. The second cooling air flow is isolated from the heat generated by the lamp assembly and is provided to the fiber ends at essentially ambient temperature.
