Abstract
The LED illuminant module for medical luminaires contains a circuit board capable of heat dissipation, an LED die package, a beam splitter, and a reflector. The LED die package is attached to the circuit board and is covered by the beam splitter, which in turn is pressed by and positioned along with the reflector. Central beams from the LED die package are collimated by the beam splitter to project forward. The side light beams are refracted by the beam splitter, intercepted by the reflector, and directed to a target coverage area along with the central light beams. The illuminant module is able to achieve low energy consumption and ease of manufacturing simultaneously.
