Lighting device for low definition display of car, has control circuit, where secondary impulse is received during interval of time having duration during which heat produced by on-impulse and by secondary impulse are evacuated by device

摘要

The device has a light source, and a control circuit that is utilized for a light source. The light source includes an electroluminescent diode or power LED that is ready to function according to an impulse mode. The control unit allows the diode to function according to another impulse mode. A secondary impulse (P) is received during an interval of time having a duration (tp) during which heat produced by on-impulse (SP) and heat produced by the secondary impulse are evacuated by the device.
