The illumination device has a base frame (12) supporting a light source (130) and a relatively movable frame (160), positioned above the light source, with an illumination lens (140) between them, controlling the radiation angle of the light. The movable frame has a light aperture (163) which can be fitted with an auxiliary frame (161) having a smaller light aperture (162), for adaption to CRT front plates of different size. |
