Abstract:
1. A vehicular lamp that irradiates amber light, comprising: a light emitting diode emitting blue light; a long-wavelength phosphor emitting light, of which a peak wavelength is substantially equal to or longer than a wavelength of the amber light according to the blue light emitting from said light emitting diode; an optical filter operable to block almost all light emitting from said light emitting diode and also to transmit almost all light, which has a wavelength similar to the peak wavelength, among light emitting from said long-wavelength phosphor to generate the amber light based on the light emitting from said light emitting diode and said long-wavelength phosphor; and a chamber comprising a lamp body and an outer lens, said chamber surrounding said diode, said long wavelength phosphor, and said optical filter.
