LED lighting systems with phosphor subassemblies, and/or methods of making the same

摘要

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.

主权项

1. An apparatus, comprising:
a first glass substrate having at least one cavity formed therein, each said cavity (a) increasing in diameter or distance from a first end thereof to a second end thereof, and (b) having a reflective surface; a lens disposed completely within the cavity and being located at the first end of the cavity; at least one light emitting diode (LED) at, or proximate to the first end of a respective one of said cavities so as to enable the reflective surface of the associated cavity to reflect at least some light emitted from the respective LED; a phosphor-inclusive material disposed over the at least one LED and over the first end; wherein the reflective surface of each said cavity is configured to conserve étendue of the light from the respective LED; and wherein each said LED is configured to produce light in accordance with a first spectrum, the phosphor-inclusive material has a second spectrum, and light exiting the apparatus has a third spectrum.
