You can recognize a motion detector that is not adjusted optimally by the fact that the lighting is switched on and off every few minutes. Incorrect or not optimal settings lead to many unnecessary switching cycles, which affects the LED lifespan. However, you should make sure that the motion detector is set up correctly.

LEDs instantly reach their full brightness after switching on and are designed for a large number of switching cycles. LED lamps, on the other hand, are perfectly suited for operation with motion detectors. Old energy-saving lamps were not suitable, because they often took several minutes to reach their full brightness and they only tolerated relatively few switching cycles. However, it’s also a question whether LED lights are suitable at all for operation with motion detectors. You already know which technical details are important for a motion detector to work with LEDs. Here problems may occur if the minimum load of the motion detector is also 10 watts or higher. For example, an old 60 watts bulb is replaced with a 10 watts LED. This is often the case especially with already installed detectors and occur after the LED conversion. In addition to the load type, you must also pay attention to the minimum load of the motion detector. If the electronic switch of the motion detector is only suitable for resistive loads, there is a high chance that problems will occur when connecting LED lamps. LED lamps are capacitive loads due to the integrated power supply. The old incandescent bulbs and halogen lamps are ohmic loads. Basically, the following load types exist: These can be found either on the detector itself, on the packaging or in the data sheet. Motion sensors with a relay are suitable for LED lights Motion sensors with an electronic switchįor motion detectors with electronic switches, you must pay attention to the load type and minimum load specifications. However, electronic switches always require a certain minimum load to function properly. Semiconductor relays generate no noise when switching and, unlike a mechanical relay contact, operate completely wear-free. This is sometimes referred to as a semiconductor relay. Many modern motion detectors, on the other hand, have an electronic switch for switching the load. Motion detectors with a relay as switching output can be identified by a quiet click sound during the switching process.
If the relay is activated during motion detection, two contacts are mechanically connected inside, similar to a normal light switch. The electrical switch for switching the lights on and off can be designed in two different ways:Īny type of load can be connected to motion detectors with an electromechanic relay. However, there is an important difference in the construction of a motion detector. In general, it does not matter whether the motion detector switches an incandescent bulb or LED light. If the sensor detects a movement, the switch is activated and the output voltage is switched on.
