Abstract
A hybrid reflector system for use in lighting application. The system is particularly well-suited for use with solid state light sources, such as light emitting diodes (LEDs). Embodiments of the system include a bowl-shaped outer reflector and an intermediate reflector disposed inside the bowl and proximate to the light source. The reflectors are arranged to interact with the light emitted from the source to produce a beam having desired characteristics. Some of the light passes through the system without interacting with any of the reflector surfaces. This uncontrolled light, which is already emitting in a useful direction, does not experience optical loss normally associated with one or more reflective bounces. Some of the light emanating from the source at higher angles that would not be emitted within the desired beam angle is reflected by one or both of the reflectors, redirecting that light to achieve a tighter beam.

19. A lamp device, comprising:
-
a light source; an outer reflector comprising a base end and an open end, said light source mounted at said base end and arranged to emit light toward said open end; an intermediate reflector disposed proximate to said light source, said intermediate reflector shaped to define a hole for at least some light from said light source to pass through; a housing arranged to surround said outer reflector without obstructing said open end; and a lens arranged to cover said open end. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A lamp device, comprising:
-
an outer reflector comprising a plurality of panels, each of said panels having a cross-section defined by a compound parabola, said panels arranged around a longitudinal axis to define a cavity and an open end; and an intermediate reflector disposed in said cavity and along said longitudinal axis, said intermediate reflector shaped to define an axial hole along said longitudinal axis. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
