Abstract
An LED head includes a circuit substrate on which a light emitting element and drive IC are mounted, a SELFOC lens for condensing the irradiating light from the light emitting element on the circuit substrate, and a head cover of aluminum for holding the SELFOC lens spaced a given distance away from the light emitting element and for radiating heat from the circuit substrate.
Claims5
An LED head comprising:
- (a) a circuit substrate on which a light emitting element and drive IC are mounted;
- (b) an array of lenses for condensing light emitted from the light emitting element;
- (c) a metallic head cover which holds the array of lenses spaced a predetermined distance away from the light emitting element, said metallic head cover communicating with the circuit substrate to radiate heat from said circuit substrate;
