发明名称 Light emitting diode
摘要 It is an object of the present invention to provide a wavelength conversion LED which improves light emitting efficiency through the use of a simple configuration. A LED comprising electrode terminals, a LED chip, a reflector having a bowl reflecting the light emitted from the LED chip to an opening, a enclosing resin filled into the bowl, and a wavelength conversion material mixed into the enclosing resin, absorbing the light emitted from the LED chip, and emitting light with a longer wavelength than that of the absorbed light is characterized in that the LED chip is connected to a electrode terminal inside the bowl, and in addition, a conductive reflective member for reflecting the light emitted from the junction surface without transparency thereof on the substantially whole surface is provided at the top surface of the LED chip, the density of the wavelength conversion material mixed into the enclosing resin is larger at the bottom of the junction surface of the LED chip than at the top thereof; and/or a wavelength conversion material layer is formed into a prescribed shape on the inside surface of the reflector with the bowl.
