控制具有至少两个半导体光源的照明元件
摘要：
本发明涉及一种用于具有至少两个半导体光源并且可连接到电源上的照明元件(12)的控制装置，用于使电源提供的电功率借助半导体光源转化为取决于所提供的电功率的、发射的光功率，其中，半导体光源连接到控制装置处，并且控制装置设置用于通过以下方式调节所提供的电功率，即控制装置具有节拍发生器(22)，其构造用于使半导体光源在节拍运行中加载电功率并且根据单独对应于半导体光源的节拍脉冲系列对其进行控制。根据本发明，节拍发生器(22)设置用于从这些节拍脉冲系列中构成一个共同的脉冲模式(I，II)，并且通过选择一个对应于该光功率的脉冲模式(I，II)来如下地调节由照明元件发射的光功率，即能够尽可能地抑制电流过高。
摘要（英）：

A control device for an illuminant having at least two semiconductor light sources and connectable to an electrical energy source, for converting an electrical power provided by the electrical energy source, by the semiconductor light sources, into an emitted light power dependent on the electrical power provided is disclosed. The semiconductor light sources are connected to the control device, and the control device is designed to set the electrical power provided by virtue of the control device including a clock generator designed to apply electrical power to the semiconductor light sources in clocked operation and to control said semiconductor light sources in accordance with clock pulse sequences individually assigned to the semiconductor light sources. The clock generator is designed to form a common pulse pattern from the clock pulse sequences and to set the light power emitted by the illuminant by selecting a pulse pattern assigned to the light power.
