The unit has an electronic compass including terrestrial magnetic field sensors (1a, 1b). The sensors are oriented at 90 degrees to each other for generating information indicator of a bend. Each sensor delivers a continuous voltage proportional to the level of magnetic field. The voltage is expressed with a proportionality relation according to an angle between the axis of sensor and the magnetic field. An independent claim is also included for a control device of a lighting system comprising a bend detecting unit. |
