Abstract
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 ILor with a second electric current IL; to switch from the first electric current ILto the second electric current ILwhen a temperature T of the light source increases and exceeds a first temperature level TLinc; and to switch from the second electric current ILto the first electric current ILwhen the temperature T increases and exceeds a second temperature level TLinc, where ILis greater than ILL and TLinc is greater than TLinc.
