Abstract
An optoelectronic light emitting device includes an optoelectronic semiconductor component configured to generate light, a current source configured to generate a current, and a PWM transistor driven by a pulse-width modulated signal. The PWM transistor enters a first state or a second state based on said pulse-width modulated signal. The PWN transistor is configured to supply the optoelectronic semiconductor component with the current generated by the current source in the first state and to decouple it from the current generated by the current source in the second state. The current source is manufactured by a first technology and the PWM transistor is manufactured by a second technology.
