Street-lighting intensity controller for decreasing energy consumption by motion detection

Dynamic lighting – Operation

Street lighting is one of the major components of energy consumption in cities. The autonomous dynamic lighting solution for the residential areas of towns and cities aims to cut electricity consumption and reduce light pollution. The adaptive dynamic lighting controllers optimize street light intensity: if there is no activity in the street the lighting is in reduced mode and once pedestrians or cyclists pass in front, the lighting is increased according to their progress.

Rapid installation and maintenance-free

eDyn is easily-fitted to existing lighting. A hole is pierced to pass the cables from eDyn to the LED driver inside the light. The unit is secured by magnets and (optional) straps. The unit is completely waterproof and uses three high-quality Japanese passive infrared sensors.

The environmental benefits

  • Electricity consumption reduction by up to 60% compared to fixed-intensity LED lighting
  • Enables 0% (full-cut) off both with DALI and 0-10V lighting
  • At least 50% electricity savings by dynamic light level control compared to fixed-intensity LED light sources
  • 90% conservation of original light fitting when used as a retrofit to existing installations

The financial benefits

  • 4-year average return on investment
  • 400 kWh average energy savings per dynamic LED light source during lifetime (10 year) compared to normal LED source

Without compromise on safety

Technical details

How it works

When the public lighting is switched on, it will be at a programmed level, which already allows energy savings to be made at this stage by choosing, for example, a level of 80% instead of 100%.

After the chosen time, activating the command line allows dynamic lighting management with energy consumption from 0 to 100%. The command line must be activated by a network remote control or a clock by switching on a defined phase of the public lighting network.

The infrared sensor switches the street light on only when a person is detected and the street needs to be lit. In order to guard against the feeling of insecurity, the integrated radio module anticipates the switching on of the streetlights when a person is moving by switching on the adjacent streetlights.

Modes of operation

  • Permanent dynamic mode (without command phase)
  • Dynamic mode as soon as the command phase is triggered


The following parameters can be modified according to the user’s wishes:

Energy management:
  • Streetlight brightness level when switching on (ON+)
  • Brightness level after detection in dynamic operation (Dyn+)
  • Reduced brightness level in dynamic operation (Dyn-)
  • Transition time between brightness levels (Tup/Tdown)
  • Duration of level maintenance after detection (Tdyn+)
Communication management:
  • Address of each module
  • Addresses to which the module is sensitive after detection of an adjacent lamppost
  • Radio transmit power and transmit channel

Circuit breaker

The eDyn module must be connected to the lamp post circuit breaker.

LED driver control

The  LED driver must be connected to the control outputs of the eDyn module. The connection must be made in the fuse box of the light point using terminals (e.g. WAGO 222-413).

Maintenance and servicing


eDyn modules are programmed by means of a programmer attached via USB cable to a computer running Windows 10/11.

eDyn programmers are available to order from JDC Electronic SA

Installation of the software

  1. Download the software here.
  2. Follow the instructions within the Readme1st.txt file to install
  3. Plug in the programmer and select the appropriate serial port connection within the software


Selection of a light point

When the program is launched, it is in listening mode and waits for the reception of a number from a light point. The program waits up to 50 seconds for an address to be received. To stop this mode, simply press any key on the keyboard.

If a light point is detected, then its number is displayed in the “Detector N°” box. If no light point is detected within 50 seconds, press the “Wait for No” button again or manually enter the number in the “Detector No” field.

In a street, the “Wait for number” mode is very practical, because all you have to do is pass under a light point for its number to be recognized directly.

Programming the number of a light point

After detecting a light point, it is possible to assign it a new number. This operation must be done conscientiously, because it involves a lot of changes. By changing the number of a light point, the interaction between the other light points on the street will no longer be established.

The new number must be entered in the “Program number” field and then transmitted using the “Program” button. If the operation went well, the new number must appear in the “Detector N°” field, otherwise, the old number will still be indicated in the “Detector N°” field.

It is very important not to assign an identical number to two light points, this would cause a communication problem.

Parameter management

Using the “Read parameters” and “Send parameters” buttons, the light point can be programmed at any time.

Lighting parameters

All parameters can be set according to the graph below:

Radio communication settings

The radio parameters can be modified according to the configuration of use in a street (spacing between the luminaires, radio pollution, etc.).

It is recommended not to change these options.

All luminaires that need to interact with each other must be on the same channel. If it is decided to use channel B, when starting the program, switch the programming box to the “BOX channel” field.

Address management

The addresses to which the light point should be sensitive can be read and programmed using the “Read addresses” and “Send addresses” buttons. Only the useful addresses must be entered, the boxes left empty will be automatically completed by the address 0.

Test number

This tool makes it possible to simulate the detection of a light point and to transmit the number of this light point, entered in the field “Send a number for test”. This makes it possible in particular to test the operation of the other light points programmed with this number.
