Zusammenfassung: | PURPOSE:To use a small-sized light source and to increase the quantity of light transmitted to optical fibers and obtain the illumination panel with high illuminance by providing a light convergence part which is formed integrally with a valve at the tip of the valve. CONSTITUTION:The light emitted by the light source 11 is transmitted to the optical fibers 13 which are bundled at one end 131 and leaks from a light leak part 132 to provide illumination as shown by an arrow X. A display panel 14 is installed in front of the light leak part 132 and illuminated with the leaking light from behind. A reflection panel 15 is installed on the opposite side from the display panel. Thus, the light emitted by the light source is converged by the light convergence part formed atop of the valve integrally to increase the efficiency of transmission to the optical fibers, and the light source can be reduced in size. Thus, the illumination panel with high illuminance is obtained by using the small-sized light source. |
