Incandescent lamp having YAG envelope

The invention deals with the introduction of an envelope made of Yttrium Aluminium Garnet (YAG) for an incandescent lamp that is filled with a gas having a relatively high fill pressure compared to conventional lamps, the gas comprising for example a halogen, for example a fluoride. The envelope combines the optical properties of quartz glass with the mechanical properties of Poly Crystalline Aluminium Oxide (PCA). Thus it is enabled to provide a miniature halogen lamp with an improved explosion resistance.
