Abstract
A lighting apparatus includes a nested reflector. The nested reflector receives a light output from a light source and directs the light output.
Claims20
A lighting apparatus, comprising:
- a light source;
- a nested reflector receiving a light output of the light source and directing the light output, the nested reflector including an outer reflector and an inner reflector, the outer reflector including a plurality of separate outer faceted reflective components which are interconnected to form the outer reflector.
A lighting apparatus, comprising:
- a light source;
- a nested reflector including a plurality of reflectors, the nested reflector receiving a light output from the light source and directing the light output, wherein the nested reflector includes an outer reflector and an inner reflector, the inner reflector being positioned relative to the outer reflector such that a focus of the inner reflector is generally aligned with a focus of the outer reflector, the light source being positioned at the focus of the outer reflector;
- and
- at least two spacers extending between inner reflector and the outer reflector to secure the inner reflector to the outer reflector, each spacer including a planar body portion aligned generally perpendicular to the light source to minimize interference with the light output emitted from the light source.
1 more element
A light emitting plasma lighting apparatus driven by a driver which generates a radio frequency (RF) output signal, the apparatus comprising:
- an emitter including a body portion having an opening therein, and a puck located in the opening of the body portion, the puck having an exposed bottom surface and a plasma bulb coupled to the bottom surface of the puck, the puck being coupled to the driver to receive the RF output signal and provide a concentrated RF field so that light is emitted from an outer surface of the plasma bulb;
- and
- a nested reflector coupled to the body portion of the emitter to shape light emitted from the plasma bulb into a collimated light pattern focused at infinity, the nested reflector including an inner reflector and an outer reflector, the inner reflector being positioned relative to the outer reflector such that a focus of the inner reflector is aligned with a focus of the outer reflector, and wherein the plasma bulb is positioned at the focus of the outer reflector.
