Abstract
Provision is made of a semiconductor radiation source having a base body on which at least two LED chips are mounted, at least one chip of which is connected to a series resistor which can be adjusted. The LED chips (12, 14) are fitted to the base body (24) using a thermally conductive connection and at least one printed circuit board (30) which bears the series resistor (40, 42) is also mounted on the base body (24).
