    • A driver device provides output current for one or more light-emitting semiconductor devices. The driver device comprises a first converter means (102) for producing a bus voltage. Said first converter means has a power rating. Two or more output stages (203, 204) are coupled to receive said bus voltage and each configured to provide, at an output power specific to the respective output stage, output current to one or more light-emitting semiconductor devices coupled to the output of the respective output stage. A common output power limiter (201) is configured to limit the sum of output powers of said two or more output stages to a combined power value that is smaller than or equal to said power rating.
    • 驱动器件为一个或多个发光半导体器件提供输出电流。 驱动器装置包括用于产生总线电压的第一转换器装置(102)。 所述第一转换器装置具有额定功率。 耦合两个或更多个输出级(203,204)以接收所述总线电压,并且每个配置成以相应输出级特有的输出功率将一个或多个发光半导体器件的输出电流提供给耦合到 各自的输出级。 公共输出功率限制器(201)被配置为将所述两个或多个输出级的输出功率之和限制为小于或等于所述额定功率的组合功率值。
