1. A vehicular lamp that irradiates umber 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 umber light according to the blue light emitting from said light emitting diode; and

    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 umber light based on the light emitting from said light emitting diode and said long-wavelength phosphor.
