In
automotive applications, LED are used mainly external and internal
lighting. External lighting equipment related to thermal limits and EMC
problems, along with the many complex unloading load testing standards,
for example, voltage is 40V, 60V, 80V, or 100V LED drive circuit must
comply with the stringent requirements of automotive EMC
specifications. For the adoption of efficient, inductive switching
regulator-driven LED, meet the above require a certain degree of
difficulty, all the preventive measures will increase the overall
program cost. In the exterior lighting applications, headlights, fog
lamps, and light is the target application. As the LED on the
advantages can be widely used LED to create a comfortable environment
inside the vehicle, such as instrument type lights, pedal lights, map
lights, rear fog lamps, rear brake and indicator light, which goes on
show car "entertainment information "flat-panel display backlighting
and atmosphere blend will further increase the LED lighting
applications.
