Abstract: A fiber optic light source cooled by a tube-axial fan having a blocking device covering a portion of its outlet. The blocking device generates a relatively higher velocity stream of cooling air just downstream of the blocking device in the direction of the rotation of the fan blades, while maintaining the velocity of cooling air is produced across the remainder of the fan outlet relatively unchanged. The higher velocity cooling air is used to cool the fiber optic cable ends while the relatively lower velocity cooling air is used to cool the bulb and other components of the light source. The dual characteristics of the cooling air produced by the fan provides an efficient, low noise cooling source that facilitates higher levels of light input without the problem of melting of the fiber optic cable ends.
