Abstract
A lighting arrangement has a lighting module with a sensor element in parallel with a light source arrangement between module terminals. A measuring system is provided for measuring, at the module terminals, a signal which is dependent on the sensor element when the light source arrangement is turned off. Thus, sensing is integrated into or connected to a lighting module, such as LED module.
Claims19
A lighting arrangement, comprising:
- a lighting module, comprising:
- a terminal arrangement comprising first and second terminals for connection to a lighting driver;
- a light source arrangement in series between the first and second terminals;
- and
- a sensor element in parallel with the light source arrangement and in series between the first and second terminals;
- a measuring system for measuring, at the terminal arrangement, a signal which is dependent on the sensor element;
- and
- an isolating switch in series with the sensor element for disconnecting the sensor element when the light source arrangement is turned on.
