    摘要: An automotive lamp including a light source driven by an electric current, and an electronic circuit configured to modify the electric current. The electronic circuit includes a plurality of discrete analog electronic components. The electronic circuit is configured to modify the electric current driving the light source so as to drive the light source with a first electric current IL1 or with a second electric current IL2; to switch from the first electric current IL1 to the second electric current IL2 when a temperature T of the light source increases and exceeds a first temperature level TL1inc; and to switch from the second electric current IL2 to the first electric current IL1 when the temperature T increases and exceeds a second temperature level TL2inc, where IL2 is greater than ILL and TL2inc is greater than TL1inc.
