Street lighting intensity controller to reduce energy consumption through motion detection
Dynamic lighting - How it works
Street lighting is one of the main contributors to energy consumption in cities. The Autonomous Dynamic Lighting solution for residential areas in cities aims to reduce electricity consumption and light pollution. Adaptive dynamic lighting controllers optimize street lighting intensity: if there is no activity in the street, lighting is reduced, and when pedestrians or cyclists pass by, lighting is increased according to their progress.
Fast, maintenance-free installation
eDyn adapts easily to existing lighting. A hole is drilled to pass the eDyn cables to the LED driver inside the luminaire. The housing is secured with magnets and clamps (optional). eDyn is totally waterproof and uses three high-quality Japanese passive infrared sensors.
Environmental benefits
- Up to 60 % less electricity consumption than fixed-intensity LED lighting
- Allows switching off at 0 % (total cut-off) with both DALI and 0-10V lighting.
- At least 50 % electricity savings thanks to dynamic lighting level control compared with fixed-intensity LED light sources
- Retention of 90 % of original lighting when modernizing existing installations.
Financial benefits
- Average return on investment over 4 years
- 400 kWh average energy savings per dynamic LED light source over its 10-year lifetime, compared with a standard LED source
No compromise on safety
Technical specifications
Street lighting operation
When street lighting is switched on, it will be at a programmed level, which means that energy savings can already be made at this stage by choosing, for example, a level of 80 % instead of 100 %.
After the selected time, activation of the control line enables dynamic lighting management with energy consumption from 0 to 100%. The control line must be activated by a network remote control or a timer by switching on a defined phase of the public lighting network.
The infrared sensor switches on the street lighting only when a person is detected and the street needs to be lit. To combat feelings of insecurity, the integrated radio module anticipates the switching on of street lights when a person moves, by switching on adjacent street lights.
Operating modes
- Permanent dynamic mode (without control phase)
- Dynamic mode as soon as the control phase is triggered
Parameters
The following parameters can be modified according to the user's wishes:
Energy management :
- Streetlight brightness level on switch-on (ON+)
- Brightness level after detection in dynamic mode (Dyn+)
- Reduced brightness level in dynamic mode (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 detecting an adjacent streetlight
- Radio transmit power and channel

Circuit breaker
The eDyn module must be connected to the streetlight 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 light point's fuse box, using terminals (e.g. WAGO 222-413).
Care and maintenance
No special maintenance is required for the eDyn system.
In case of problem, please contact us directly.
Important: the eDyn module must never be opened by a third party.
Programming
eDyn modules are programmed using a programmer connected by USB cable to a PC running Windows 10/11.
eDyn programmers are available to order from JDC Electronic SA.
Software installation
Watch out! Do not connect the USB cable before installing the software.
- Download the software from the Downloads section from here.
- Follow the instructions in the Readme1st.txt file to install it.
- Plug in the programmer and select the appropriate serial port connection in the software.
Programming
Light point selection
When the program is launched, it is in listening mode, waiting to receive a light point number. The program waits up to 50 seconds for an address to be received. To stop this mode, simply press any key on the keypad.
If a light point is detected, its number is displayed in the "Detector No." box. If no light point is detected within 50 seconds, press the "Wait for N°" button again, or enter the number manually in the "Detector N°" field.
On a street, the "Wait for No." mode is very practical, as you simply pass under a spotlight and the number is directly recognized.
Programming a light point number
Once a light point has been detected, it can be assigned a new number. This operation must be carried out carefully, as it involves many changes. By changing the number of a light point, the interaction between other light points on the street will no longer be established.
The new number must be entered in the "Programming No." field and then transmitted using the "Program" button. If the operation was successful, the new number should appear in the "Detector No." field, otherwise, the old number will still appear in the "Detector No." field.
It is very important not to assign identical numbers to two light points, as this would cause communication problems.
Parameter management
Using the "Read parameters" and "Send parameters" buttons, the light point can be programmed at any time.
Luminaire parameters
All parameters can be set according to the graph below:
Radio communication parameters
Radio parameters can be modified to suit street conditions (luminaire spacing, radio pollution, etc.).
It is recommended not to change these options.
All luminaires that are to interact with each other must be on the same channel. If you decide to use channel B, switch the programming box to the "BOX channel" field when starting the program.
Address management
The addresses to which the light point is to be sensitive can be read and programmed using the "Read addresses" and "Send addresses" buttons. Only useful addresses need be entered; empty boxes are automatically filled with address 0.
Test number
This tool simulates the detection of a light point and sends the number of this light point, entered in the "Send number for test" field. This makes it possible to test the operation of other light points programmed with this number.
