摘要： LED light source comprising a string of LED loads (LED1-LED4) supplied by a rectified mains voltage. The number of LED loads carrying current is increased as the momentary amplitude of the rectified mains voltage increases, and is decreased as the momentary amplitude of the rectified mains voltage decreases. The order in which the LED loads start carrying a current and the order in which the LED loads stop carrying a current is reversed for each half period of the mains.
摘要翻译： LED光源包括由整流电源电压提供的一串LED负载（LED1-LED4）。负载电流的LED负载的数量随着整流电源电压的瞬时幅度的增加而增加，并且随着整流电源电压的瞬时幅度的减小而减小。 LED负载开始承载电流的顺序以及LED负载停止承载电流的顺序在主电源的每个半周期都相反。

摘要： A series arrangement of LED loads (LP1-LP4) is coupled between output terminals of a rectifier having its input terminals coupled to a mains supply supplying a low frequency AC voltage. Control means render the LED loads conductive one by one, when the amplitude of the supply voltage increases, and non-conductive one by one when the amplitude of the supply voltage decreases. The first LED load (LP1, LP2) has a forward voltage that is substantially higher than that of the other LED loads. As a consequence, the LED utilization is comparatively high, thus allowing the LED loads used in the series arrangement to be comparatively cheap.
摘要翻译： LED负载（LP1-LP4）的串联布置耦合在整流器的输出端子之间，其输入端子耦合到提供低频AC电压的电源。当电源电压的幅度增加时，控制装置使LED负载一个接一个，当电源电压的幅度减小时，LED逐一导通。第一个LED负载（LP1，LP2）具有远高于其他LED负载的正向电压。因此，LED利用率相对较高，从而允许串联装置中使用的LED负载相当便宜。

摘要： The invention relates to a method and a device for driving an LED string of a first LED segment (11) and at least one further LED segment (12, 13, 14) connected in series. Each LED segment has at least one light emitting diode, LED. The LED string is powered by a rectified AC mains voltage. The first LED segment (11) is powered when the rectified AC mains voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC mains voltage is above a second voltage level higher than the first voltage level. The first LED segment emits light having a first color temperature, and the further LED segment emits light having a second color temperature higher than the first color temperature. The light emitted by the first LED segment and the light emitted by the further LED segment are superimposed. The color temperature change of the light emitted by the LED string, when dimmed, resembles the color temperature change of an incandescent lamp.

In order to make the LED light source compatible with a phase cut dimmer, the LED light source is further equipped with—a switchable bleeder current source coupled between the first and second output terminal of the full bridge rectifier, —a latch coupled between the first and second output terminals of the full rectifier bridge and comprising a series arrangement of a resistor and a capacitor to prevent the current through the dimmer from crossing zero after a leading edge generated by the phase cut dimmer, in case the phase cut dimmer is a leading edge phase cut dimmer, —a unidirectional element arranged in series with the capacitor for preventing discharging of the capacitor via the LED loads or the adjustable bleeder current source, and—a clamp circuit coupled to the capacitor and comprising a current source for discharging the capacitor and providing a low ohmic path for the dimmer current when the dimmer is off.

摘要： A transducer device for detecting an environmental state within a biological material including a channel comprising a fluid, a hydrogel material, which is adapted to change its volume when getting into contact with an environmental material and/or when detecting an environmental change, and which is mechanically coupled to the channel such that the volume of the channel changes when the volume of the hydrogel material changes. The transducer device further includes a sensor, which is adapted to generate a signal upon detection of the change of a physical property of the fluid that is induced by the volume change of the channel. By applying the transducer device, an accurate monitoring of physiological parameters, for which the hydrogel material is sensitive is possible. It is also possible to apply the transducer device outside of the bodily lumen, for example to monitor the blood of a patient outside the bodily lumen.
