  • Publication number: 20150023032
    Abstract: A current controlling apparatus for an automotive lamp is provided that adjusts a current applied to the automotive lamp that uses laser light as a light source to adjust the intensity of the laser light. The automotive lamp includes a light source that generates laser light and a phosphor excited by the generated laser light to generate light of a predetermined color. A minor is configured to transmit therethrough a first portion of the generated laser light while reflecting a second portion of the generated laser light. A light receiver is configured to receive reflected laser light from the minor and output an output signal based on an intensity of the received laser light. In addition, a controller is configured to detect an intensity of the generated laser light based on the output signal and adjust a current applied to the light source based on results of the detection.
