ABSTRACT:
The disclosed subject matter aims to provide a vehicle lighting device and an LED light source therefore. Accurate temperature detection of an LED chip and associated phosphor can be monitored in real time. The LED light source can include at least one LED chip mounted on a base and a phosphor layer disposed adjacent the LED chip. A mixed particulate phosphor for generating fluorescence through light emitted from the above LED chip can also be provided. The LED light source can be configured to output mixed color light containing the light from the LED chip and the fluorescence from the phosphor. The LED light source can also include a temperature detecting element located on the base and LED chip to detect the temperature on the periphery of the LED chip.
