摘要：
A pulse modulated illumination source comprises at least one light emitting device, and a power source with a first and a second output terminal for generating a DC current to be supplied through said at least one light emitting device connected between said first and second output terminals of said power source. The illumination source further comprises a first controllable switching device and a first signal generator for generating a first electrical control signal for said first controllable switching device, said first controllable switching device being connected in parallel to said at least one light emitting device between said first and second output terminals of said power source. The illumination source further comprises a second controllable switching device and a second signal generator for generating a second electrical control signal for said second controllable switching device, said second controllable switching device being connected in series with said at least one light emitting device and said second control signal being out of phase with said first control signal such that said second controllable switching device opens and decouples said light emitting device from said power source when said first controllable switching device closes.
摘要（中）：
脉冲调制照明源包括至少一个发光器件和具有第一和第二输出端的电源，用于产生要通过连接在所述第一和第二输出端之间的所述至少一个发光器件供应的直流电流 说电源。 照明源还包括第一可控开关装置和第一信号发生器，用于产生用于所述第一可控开关装置的第一电控信号，所述第一可控开关装置与所述至少一个发光装置并联连接在所述第一和 所述电源的第二输出端子。 照明源还包括第二可控开关装置和第二信号发生器，用于产生用于所述第二可控开关装置的第二电控信号，所述第二可控开关装置与所述至少一个发光装置和所述第二控制器串联连接 信号与所述第一控制信号异相，使得当所述第一可控开关装置关闭时，所述第二可控开关装置打开所述发光装置并将其从所述电源解耦。
