<p>The apparatus includes a microwave generator (1, 2) which is connected through a feeder (3, 5) to cavity (49) defined by a light-reflecting member (4) and a member (9) which is transparent to light but opaque to microwaves. An electrodeless discharge bulb (6) contains substance for discharge light emission and is located in the cavity (49) so that the latter operates resonantly when the bulb (6) is emitting light. The bulb is sufficiently small as to provide, effectively, a point light source.</p> |
