LED light source module for flashlights

A module for an LED light source Coupled to a power source, comprising:

• a housing;
• an LED light source coupled to the power source;
• a heat sink coupled to the housing, the LED light source thermally and mechanically coupled to the heat sink;
• a single reflector coupled to the housing and having an optical axis, the LED light source being positioned by the heat sink about the optical axis and being optically coupled to the single reflector, the LED light source being positioned with respect to the single reflector to radiate substantially all of the light generated by the LED light source directly toward the single reflector, which single reflector then reflects the light into the forward light output direction of the module after a single reflection, the single reflector reflecting nearly all of the light from the LED light source in the forward light output direction;
• an LED power circuit disposed in the body for providing power from the power source to the LED light source;
• a circuit board disposed in the housing on which the LED power circuit is mounted;
• wherein nearly 100% of the LED light is captured and distributed by the single reflector.
