LIGHT EMITTING DEVICE FOR WAVELENGTH CONVERSION AND WAVELENGTH CONVERSION METHOD THEREOF

摘要

PURPOSE: A wavelength changeable light emitting device is provided to reduce a manufacturing cost by obtaining a desired color with only the replacement of a selection reflecting unit. CONSTITUTION: A light source unit(10) includes an LED(12). A light source body(14) electrically connects the LED with a flexible printed circuit board(40). A selection reflecting unit(20) selectively reflects light from the light source unit. The selection reflecting unit includes a dome-shaped body unit(22) and a hook-shaped hooking member(24). A wavelength changing unit(30) changes a wavelength of the light reflected from the selection reflecting unit to reflect the light to the selection reflecting unit again.
