ABSTRACT:
A dental handpiece with integrated light source has on its casing a socket for a lamp carrier which in turn has a lamp socket. An incandescent lamp is inserted into said lamp socket. In those regions in which the incandescent lamp is covered up by the lamp carrier or parts of the casing a reflecting layer is provided on the outer surface of the incandescent lamp. This may be, for example, a metal film deposited by vaporisation onto the outer surface of the lamp in the appropriate region. The lamp carrier is molded onto the partially vapor-coated incandescent lamp.
