PURPOSE: A light emitting diode (LED) is provided to arrange a reflector on the central axis of a lens, thereby removing a hot spot. CONSTITUTION: An LED is mounted on a printed circuit board (PCB). A lens (30) has an incident surface and an emitting surface. A wavelength conversion material (31) contains a fluorescent substance. A reflector (33) is located on the wavelength conversion material. The wavelength conversion material and the reflector are located on the central axis of the lens. |
