Light source using light emitting diodes and an improved method of collecting the energy radiating from them
First Claim
1. An apparatus comprising:
- a light source;
a reflector positioned to reflect light from the light source which is radiated from the light source in a peripheral forward solid angle as defined by the reflector defined about an optical axis; and
a first lens disposed longitudinally forward of the light source for focusing light into a predetermined pattern which is radiated from the light source in a central forward solid angle as defined by the lens, so that the apparatus projects a composite beam of light comprised of the light radiated in the central forward solid angle and peripheral forward solid angle.

Abstract
An LED or incandescent light source is positioned in a reflector arranged to reflect light from the LED or incandescent light source which is radiated from the LED or incandescent light source in a peripheral forward solid angle as defined by the reflector. A lens is disposed longitudinally forward of the LED or incandescent light source for focusing light into a predetermined pattern which is radiated from the LED or incandescent light source in a central forward solid angle as defined by the lens. The apparatus comprised of the combination projects a beam of light comprised of the light radiated in the central forward solid angle and peripheral forward solid angles.

27. A method comprising:
-
radiating light from a light source;
reflecting light into a first predetermined beam portion, which light is radiated from the light source in a peripheral forward solid angle; and
focusing light into a second predetermined beam portion, which light is radiated from the light source in a central forward solid angle. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 50)

47. An improvement in a flashlight having a body, a power source, a light source electrically connected to the power source, and a reflector with reflective surfaces for reflecting light from the light source, the improvement comprising:
-
a configuration of the reflector to reflect the light in a peripheral forward solid angle; and
a lens disposed longitudinally forward of the light source for focusing light into a predetermined pattern which is radiated from the light source in a central forward solid angle as defined by the lens so that a composite beam of light is projected which beam is comprised of the light radiated in the central forward solid angle and peripheral forward solid angle. - View Dependent Claims (48, 49)
