Apparatus and a method for operating a variable pressure sealed beam lamp
First Claim
1. A sealed high intensity illumination device configured to receive a laser beam from a laser light source comprising:
- a sealed chamber configured to contain an ionizable medium, the chamber further comprising;
a plasma sustaining region;
a plasma ignition region;
a high intensity light egress window configured to emit high intensity light from the chamber; and
a substantially flat ingress window located within a wall of the chamber configured to admit the laser beam into the chamber; and
a pump system for controlled increasing and decreasing a pressure level of the ionizable medium within the sealed chamber.

Abstract
An apparatus and a method for operating a sealed high intensity illumination lamp configured to receive a laser beam from a laser light source. The lamp includes a sealed chamber configured to contain an ionizable medium having a plasma sustaining region, and a plasma ignition region. A high intensity light egress window emits high intensity light from the chamber. A substantially flat ingress window located within a wall of the chamber admits the laser beam into the chamber. The lamp includes means for controlled increasing and decreasing a pressure level within the sealed chamber while the lamp is producing the high intensity illumination.

11. A sealed high intensity illumination device configured to receive a laser beam from a laser light source comprising:
-
a sealed chamber configured to contain an ionizable medium, the chamber further comprising; an ingress lens located within a wall of an integral reflective chamber interior surface of the sealed chamber, wherein the integral reflective chamber interior surface is configured to focus the laser beam to a lens focal region within the chamber; a plasma sustaining region corresponding to the lens focal region; a high intensity light egress window configured to emit high intensity light from the chamber; an integral reflective chamber interior surface configured to reflect high intensity light from the plasma sustaining region to the egress window; and a non-integral reflector disposed within the chamber between the plasma sustaining region and the egress window, wherein the non-integral reflector is configured to reflect high intensity light from the plasma sustaining region toward the integral reflective chamber interior surface; and a pump system configured for controlled increasing and decreasing a pressure level within the sealed chamber, wherein a path of the laser beam from the laser light source through the ingress lens to a focal region within the chamber is direct, and the non-integral reflector is configured to prevent direct transmission of light from the plasma sustaining region to the egress window. - View Dependent Claims (12, 13, 14)

15. A method for operating a sealed beam lamp, the lamp comprising a sealed ionizable medium chamber, a laser light source disposed outside the chamber, and a lens configured to focus the laser beam to a focal region within the chamber, comprising the steps of:
-
setting a pressure of the chamber to a first pressure level; igniting the ionizable medium within the chamber; and controlling a pressure change from the first pressure level of the chamber to a second pressure level without extinguishing the ionizable medium. - View Dependent Claims (16, 17, 18, 19)
