So, the first scheme for connecting the LED spotlight to the sensor is as follows: 
As you can see, three wires are connected to the junction box on the street: phase, ground and zero. The PE wire( ground) is only needed if the lamp body is metal. Everything is quite simple - the phase is being torn apart, zero to each device.
If you bought a touch-sensitive lamp( the sensor is already installed in the case), it is recommended to connect it additionally to the photo-relay, which automatically turns on the light when darkness comes. Here the layout of the electrical wires is not much more complicated: zero is output to each of the devices, the phase first goes to the photo relay, and then to the luminaire.
Connection diagram of the sensor with a light source: 
The principle of operation with this connection is as follows: when the night falls, the light switch closes the circuit, so that the current is applied to the terminals of the halogen floodlight. As soon as a person appears in the detection zone, the sensor will react and close its circuit area, so that the halogen lamp will light up.
Well, the latter option is suitable in the event that you bought a simple LED spotlight( without an ambient light sensor and motion).In this case, be sure to supplement the electrical circuit with two sensors connected in series, as shown below. 
The last two connection options will make street lighting economical and fully automatic, so we recommend using one. If you bought a 12v lamp, then you need to connect it to the network only through a 220/12 Volt power supply. Connecting directly to the mains will disable the lamp.
In addition, we recommend watching a video that clearly shows how to connect a street lamp to a 220 volt network:
wires. That's all I wanted to tell you about this issue. As you can see, the connection diagram of the LED spotlight with the motion sensor and the photorelay is quite simple! Finally, it is recommended to connect the street light only through the machine that will be installed in the switchboard on the street. This will allow for safe repair of the searchlight, becausein these circuits only the sensors are disconnected.
