Claims15
A glass envelope for a light emitting device comprising a first and a second glass member, each member having an inner surface, the first member having a continuous channel opening on its inner surface, the second member having an integral, optical element formed in or on at least one surface, the continuous channel and the integral, optical element being aligned so that light generated in the channel is directed by the optical element, the glass members being hermetically joined to enclose the continuous channel.
A discharge lamp comprising a laminated, sheet envelope, the envelope having a first and a second glass sheet, each sheet having an inner surface, the first sheet having a continuous channel that opens on its inner surface, the channel containing a gas that generates light when excited, the second sheet having an integral, optical element in or on at least one surface, the continuous channel and the integral, optical element being aligned so that a substantial amount of the light generated in the channel is redirected by the optical element, the glass sheets being hermetically joined to enclose the continuous channel.
