Light emitting diode lamp with conically focused light guides
View Patent ↗A lamp component has a support with a base surrounded by an interior wall defining a cavity with a central axis. A plurality of LEDs are supported on the interior wall and generally aimed to direct light towards the central axis. A center piece has a first reflective surface shaped and positioned to intercept light received from the LEDs and reflect such received light generally in a direction parallel to the axis.
1. A lamp component comprising:
a support having a base surrounded by an interior wall defining a cavity with a central axis;
a plurality of LEDs supported on the interior wall and generally aimed to direct light towards the central axis; and
a centerpiece with a first reflective surface shaped and positioned to intercept light received from the LEDs and reflect such received light generally in a direction parallel to the axis;
further including one or more optical guides located adjacent the respective LEDs, each respective optical guide having a reflective surface directing light towards the center piece; and
wherein the optical guides have light transmissive solid bodies with an input surface adjacent a respective LED to receive light therefrom, and having an internally reflective surface directing light and an output window transmitting light from the LED and the internally reflective surface to the first reflective surface, and
wherein the solid bodies output window that passes received light from the LED to the exterior in a direction towards the first reflective surface has lens features to focus light in the direction of the first reflective surface.
2. A lamp component comprising:
a support having a base surrounded by an interior wall defining a cavity with a central axis;
a plurality of LEDs supported on the interior wall and generally aimed to direct light towards the central axis; and
a centerpiece with a first reflective surface shaped and positioned to intercept light received from the LEDs and reflect such received light generally in a direction parallel to the axis;
further including one or more optical guides located adjacent the respective LEDs, each respective optical guide having a reflective surface directing light towards the center piece; and
wherein the optical guide is a hollow reflector body with an input opening adjacent a respective LED to receive light therefrom, an internally reflective surface directing light and an output window transmitting light from the LED and the internally reflective surface to the first reflective surface.
3. The lamp component in claim 2 , wherein the hollow reflector body directs light to the exterior in direction towards a lens to focus light in the direction of the first reflective surface.
4. The lamp component in claim 2 , wherein the support includes heat sinking features to conduct heat from the LEDs.
5. The lamp component in claim 2 , further including an optical element spanning the axial projection of the first reflector.
6. The lamp component in claim 5 , wherein the optical guide is a fiber optic.
7. The lamp component in claim 5 , wherein the optical guide is a lens.
8. The lamp component in claim 5 , wherein the optical guide is a light pipe.
9. The lamp component in claim 2 , further wherein the LEDs are mounted on the interior surface of a carrier, and the optical guides are substantially co-formed as a reflector body glidingly fittable to the carrier.
