摘要：: <P>PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture and its LED light source that can do real-time detection of a precise temperature of an LED chip and phosphors. <P>SOLUTION: The light emitting diode (LED) light source includes at least one LED chip 22 mounted on a substrate 21 and a phosphor layer 25 that is arranged so as to surround these LED chips and into which particulate phosphors are mixed to generate fluorescence by light from the said LED chip, and is formed so as to externally emit color mixture out of light from the LED chip and fluorescence from the phosphors, wherein the LED light source includes a temperature detection device 23 that is mounted adjacent to the LED chip 22 on the substrate 21, and the LED light source 11 is structured such that the temperature around the LED chip 22 is detected by the temperature detection element 23. <P>COPYRIGHT: (C)2007,JPO&INPIT
