This is a spacer member for absorbing light that is inserted to prevent A black plate made of synthetic resin with a U-shaped cross section that is almost the same shape as 12 is used, It is fitted inside the lamp cover plate 12. This light buffer member 13 is a prism If it is arranged so as to completely cover the range of the cutout recess 5a of the plate 5, the light is blocked. And the part centered on the light source becomes darker than others, so it is an ellipse. By piercing the through hole 13a, the illuminance is restored in a so-called hollow state. The light intensity is adjusted.

[0017]   The lamp cover plate 12 is combined with the light buffering member 13 to provide a color that also serves as a diffuser. A cutout concave portion 5a of a prism plate 5 accommodating a cold cathode discharge tube 6 in the rear portion of the filter 4. Is disposed so as to cover. In this case, the lamp cover plug facing the cold cathode discharge tube 6 The white surface 12a inside the rate 12 is a through hole 13a (13b) of the light buffer member 13. Is exposed, and the surrounding area is masked with a black light buffer member 13. Be done. Therefore, the light amount is adjusted by the light buffering member 13, and the light source is centered on the light source. Only the part that does not shine brighter than the others.
