Abstract
A ceramic discharge lamp and a method of making the lamp includes a ceramic discharge chamber with two concave parts that are attached to each other at a seam, and a ceramic reflector directly attached to an exterior surface of the discharge chamber at the seam, or directly attached to a ceramic capillary that is attached to one of the two concave parts. The lamp finds particular application where focused light is required, such as injection of light into a fiber optic device. The lamp can be very small and has an advantage that the discharge chamber is isolated from the reflective surfaces so that the optically active parts of the reflector are not covered with salt from the preferred metal halide lamp fill.
