Method for triggering a sensor-controlled lamp

The method of one of the foregoing claims, wherein a turn-off signal is output via the microprocessor (14) when the sensor signal (ε) exceeds an emergency-OFF limit value stored in the memory of the microprocessor (14).

The method of one of the foregoing claims, wherein sensor signals (ε) detected during a light changing cycle, for instance a daily cycle, are stored in the memory of the microprocessor (14) and from them a characteristic curve is ascertained, from which a conclusion can be drawn about the cycle time (t) as a function of the sensor signal (ε) detected.

The method of one of the foregoing claims, wherein the lamp (1) has sensors (8, 10), and a microprocessor (14) processes the sensor signals (ε) separately from one another or jointly in weighted fashion and outputs control signals to a lamp controller for the luminous medium.

The method of one of the foregoing claims, wherein upon connection to the power supply or when the sensors (8, 10) are covered, a test cycle is performed, in which the lamp (1) is turned on and off at predetermined time intervals.

The method of one of the foregoing claims, wherein a predetermined turn-on value (εE) is varied as a function of the incident light at the time when the lamp (1) is put into operation.

A sensor-controlled lamp, which in particular is triggerable by the method of one of the foregoing claims, having at least one sensor (8, 10) for detecting the incident light and having a control unit for triggering the lamp (1) as a function of the sensor signal (ε), characterized by a microprocessor (14) for detecting a change over time in the sensor signal (dε/dt), for storing the sensor signals and operating parameters and limit values (E1, E2) in memory, and for outputting a control signal for changing an operating state of the lamp (1) if the sensor signal (ε) exceeds or undershoots one of the limit values (εE, εA).
