Street lighting in the country must be of high quality, durable and at the same time economical. To really be like that, you need it as a lighting device. In addition, a motion detector and a light sensor must be connected to this lamp, which will turn on the lighting in the area only when it gets dark and only if a person enters the detection zone. As a result, the street light will not work all night, but only when necessary, which will save a significant amount of money, especially if an LED lamp is installed inside the lamp. Next, we will consider the most effective and at the same time simple schemes for connecting a spotlight to a motion sensor and a photo relay.

So, the first scheme for connecting an LED spotlight to a sensor is as follows:

As you can see, three wires are brought into the junction box on the street: phase, ground and zero. The PE wire (ground) is needed only if the luminaire housing is metal. Everything is quite simple - the phase is broken, zero to each device.

If you have bought a sensor lamp (the sensor is already installed in the housing), it is recommended to additionally connect it to a photocell, which automatically turns on the light when it gets dark. Here, the wiring of electrical wires is not very complicated: zero is output to each of the devices, the phase first goes to the photo relay, and then to the lamp.

The principle of operation with such a connection is as follows: when night falls, the photo relay closes the circuit, as a result of which current is supplied to the terminals of the halogen spotlight. As soon as a person appears in the detection zone, the sensor will react and close its section of the circuit, as a result of which it will light up.

Well, the last option is suitable if you bought a simple LED spotlight (without a light and motion sensor). In this case, be sure to complete the wiring diagram with two sensors connected in series as shown below.
