Abstract

PURPOSE:To eliminate the discolor or deformation of a color filter by heat by mounting a plurality of LEDs having different light emitting spectra and wavelengths on respective printed boards, and selectively solely or totally firing all LEDs simultaneously at every board by a changeover switch. CONSTITUTION:An LED 22 which emits a green light of wider spectrum than an LED 12 is mounted on a doughnut-shaped printed board 17. In other words, the LEDs of the prescribed light emitting colors are so mounted on the respective boards as to sequentially widen the spectra toward the front lens side from a base 12 side. The stay 15 of a printed board 14 is mounted in an implanted state to a partition plate 32, and a changeover switch 24 is provided on a rear cover 12. The switch 24 is operated to be switched by a knob 25 projected externally to connect the switch 24 with a power source and to connect with printed boards 14, 16, 17 to selectively fire the LEDs. Thus, desired emitting color light can be obtained merely by firing the LED of the desired color without necessity of a shutter and color filters.
