LED LIGHTING SYSTEMS AND/OR METHODS OF MAKING THE SAME
First Claim
1. A method of making a light fixture, the method comprising:
- forming at least one cavity in a glass substrate, the at least one cavity being tapered along a depth thereof so that the at least one cavity increases in diameter or distance from a first end thereof to a second end thereof;
disposing a reflective element on a surface of the at least one cavity; and
locating a light emitting diode (LED) at or proximate to the first end of each said cavity so as to enable the associated reflective element to reflect at least some light emitted from the respective LED, substantially conserving é
tendue of the light from the respective LED.

Abstract
Certain example embodiments relate to improved lighting systems and/or methods of making the same. In certain example embodiments, a lighting system includes a glass substrate with one or more apertures. An LED or other light source is disposed at one end of the aperture such that light from the LED directed through the aperture of the glass substrate exits the opposite end of the aperture. Inner surfaces of the aperture have a mirroring material such as silver to reflect the emitted light from the LED. In certain example embodiments, a remote phosphor article or layer is disposed opposite the LED at the other end of the aperture. In certain example embodiment, a lens is disposed in the aperture, between the remote phosphor article and the LED.

13. A method of making a light fixture, the method comprising:
-
forming at least one cavity in a glass substrate, the at least one cavity being tapered along a depth thereof so that the at least one cavity increases in diameter or distance from a first end thereof to a second end thereof; disposing a reflective element on a surface of the at least one cavity, the reflective element being adapted to reflect at least some light from a light source locatable at or proximate to the first end of each said cavity in order to substantially conserve é
tendue of the light from the light source.
