Problems solved by technology

However, light-emitting diodes also have shortcomings. The most obvious feature is that as the working temperature of the light-emitting diode light source rises, the light-emitting diode light source will experience light attenuation, and its light output efficiency will decrease accordingly. As a light source for car lights, it is likely to exceed Specification requirements for automobile lamps

Abstract

The invention provides a car lamp light source. The car lamp light source comprises an LED (light emitting diode) light source module, a control module, a light source driving module and a semiconductor cooler driving module. The LED light source module comprises a high thermal conductive substrate, an LED fixedly arranged on the high thermal conductive substrate, a photosensitive element for monitoring light emitting intensity of the LED and a thermosensitive element for monitoring working junction temperatures. The bottom portion of the high thermal conductive substrate is connected with a semiconductor cooler. The control module connects the photosensitive element and the thermosensitive element. The light source driving module is connected between the control module and the LED. The semiconductor cooler driving module is connected between the control module and the semiconductor cooler. The semiconductor cooler can adjust the temperature of the LED under the drive of the control module and the semiconductor cooler driving module; the light emitting brightness of the LED can be adjusted in real time through the photosensitive element and the light resource driving module, so that the car lamp light source can provide a stable output light source for a car lamp and meet light distribution requirements of the car lamp.

Description

technical field [0001] The invention relates to a car light source, in particular to a car light source with a light emitting diode as a light source. Background technique [0002] Light-emitting diodes have been widely used as light sources, especially in the field of brake lights. In recent years, light-emitting diode headlights are also being gradually promoted, and the world's major well-known car manufacturers have successively launched their own light-emitting diode headlight cars. For example: Audi Q5 uses 8 high-power white light-emitting diodes as the low beam light source of the car headlights. Light-emitting diodes have the advantages of long life, high reliability, and fast response, which cannot be replaced by other light sources. However, light-emitting diodes also have shortcomings. The most obvious feature is that as the working temperature of the light-emitting diode light source rises, the light-emitting diode light source will experience light attenuatio...
