Embodiment Construction

[0024] The figure shows an electric lamp 1 designed as a fluorescent lamp, which comprises a bulb 2 . In this exemplary embodiment, the bulb 2 is tubular and extends linearly in the form of a rod. At the opposite end regions of the bulb 2 are arranged bases 3 and 4 , on which two electrical connection contacts 5 a and 5 b and 6 a and 6 b are respectively arranged. A first filament, not shown, is connected to the connection contacts 5 a and 5 b and extends into the interior of the bulb 2 in the region of the base 3 . The second filament extends in a corresponding manner into the bulb 2 in the region of the base 4 and is connected to the connection contacts 6a and 6b.

[0025] A sensor device 7 is detachably arranged on the outer side 21 of the bulb 2 . The sensor device 7 comprises one or more sensors which are mounted on the holding element 8 . The retaining element 8 can be a collar surrounding the bulb 2 completely or only partially. The collar is preferably made of a he...

Abstract

The invention relates to an electric lamp comprising a light bulb (2) on which a sensory mechanism (7) is disposed that is designed to detect operating parameters of the lamp (1).

Description

technical field [0001] The invention relates to an electric lamp, in particular a fluorescent lamp, having a bulb. Background technique [0002] Electric lamps of various configurations and functions are operated by operating devices, such as electronic ballasts, for which the ambient conditions, degree of pollution or aging of the lamps or luminous means are not known. Therefore, an operating mode that is suitable for all operating situations is often selected, but this operating mode usually does not correspond to the optimal operating mode. [0003] In the known solutions, grid-fed sensors are implemented which are associated with a wiring outlay. The disclosed refinement is relatively imprecise with regard to the detection of the measured variables and only guarantees a limited improvement of the above-mentioned problems. Contents of the invention [0004] The object of the invention is to realize an electric lamp which can be operated more efficiently. [0005] Thi...
