    Abstract: 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.

    Abstract: The invention relates to a sensor probe (100,110,120,130,140,150) for detecting an environmental state within a bodily lumen. The sensor probe (100,110,120,130,140,150) having an elongated body (9) comprises an optical guide (1) having an outcoupling surface (11),which is part of an end surface (3) of the elongated body (9), facing a reflective surface of an overhanging part (22,42,52,62), a photodetector which detects a property of light which is composed of light (32) in the optical guide (1) that is reflected from the outcoupling surface (11) of the optical guide (1) and of light (33) in the optical guide (1) that is reflected from the overhanging part (22,42,52,62), and a hydrogel material(2) of which a property changes when getting into contact with an environmental material and/or when detecting an environmental change, and which is provided between the end surface (3) of the elongated body (9)and the overhanging part (22,42,52,62). In this way a sensor probe (100,110,120,130,140,150) is provided that, because of its compactness, can be applied inside the bodily lumen for detecting and characterizing parameters that are vital indicators for the state of the human or animal body, and to which the hydrogel material (2) is responsive.
