Problems solved by technology

[0005] A disadvantage of these known testing devices is that it is not possible to check lighting devices with integrated ballast electronics (Vorschalt-Elektronik)
Thus, for example, so-called energy-saving lamps (Stromsparlampen) with integrated electronic ballasts (Vorschaltgeraet) cannot be fully tested using testing devices of the prior art

Embodiment Construction

[0028] figure 1 A simplified circuit block diagram of a detection device 1 for a lighting device 3 according to the invention is shown. The detection equipment 1 is mainly composed of a providing device 5, which is used to provide a test frequency f p The test voltage V p . Test voltage V p Can be applied to insulating contact surfaces 7 . The contact surface 7 is suitably arranged so that the test voltage V p Capacitively coupled to a socket 3 a of the lighting device 3 . Due to losses in capacitive coupling, the coupled test voltage V pa below the test voltage V p , that is to say, the output voltage of the supply device 5 must be selected correspondingly larger, so that the coupled test voltage V pa corresponding to the rated voltage V n . like figure 1 As shown, the detection equipment also includes a device for measuring the coupled test voltage V pa The measuring device 8. The measuring device 8 is configured as a capacitive measuring device by means of anot...

Abstract

A testing device (1) for lighting means (3) operated at a nominal voltage (Vn) and at a nominal frequency (fn), having a capacitive coupling of a test voltage (Vp) at a testing frequency of (fp) to the lighting means (3), wherein a coupled test voltage (Vpa) corresponds to the nominal voltage (Vn), and a coupled test frequency (fpa) corresponds to the nominal frequency (fn).

Description

【Technical field】 [0001] The invention relates to a testing device for lighting installations as mentioned in the superordinate concept of claim 1 . 【Background technique】 [0002] Various testing devices for lighting devices are known from the prior art. [0003] For example, US 3,688,185 mentions a detection device for fluorescent lamps based on two different measurement principles. On the one hand, such a testing device includes a device for continuity testing of a filament of a fluorescent lamp, by means of which it is checked whether an electrically conductive contact can be made by passing the filament of the fluorescent lamp. In addition, a coil is provided, by means of which a high-frequency electromagnetic field can be coupled into the fluorescent lamp in order to check whether a sufficient gas filling of the fluorescent lamp is present. If there is a sufficient gas filling of the fluorescent lamp, it is sufficiently excited by the high-frequency electromagnetic f...
