Public lighting intensity controller to reduce energy consumption by detecting movement
Dynamic lighting - How it works
Street lighting is one of the main contributors to energy consumption in towns and cities. The autonomous dynamic lighting solution for residential areas in cities aims to reduce electricity consumption and light pollution. Adaptive dynamic lighting controllers optimise the intensity of street lighting: if there is no activity in the street, the lighting is reduced, and when pedestrians or cyclists walk past, the lighting is increased according to their progress.
Quick, 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 using magnets and clamps (optional). eDyn is fully waterproof and uses three high-quality Japanese passive infrared sensors.
The benefits for the environment
- Reduction in electricity consumption of up to 60 % compared with fixed-intensity LED lighting
- Allows switching off at 0 % (total switch-off) with both DALI and 0-10V lighting.
- At least 50 % electricity savings thanks to dynamic control of lighting levels compared with fixed-intensity LED light sources
- Retention of 90 % of original lighting in the case of modernisation of existing installations.
Financial benefits
- Average return on investment over 4 years
- 400 kWh energy savings on average per dynamic LED light source over its lifetime (10 years) compared with a normal LED source
No compromise on safety
Technical specifications
How street lighting works
When the 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, activating 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 only switches on the street lighting when a person is detected and the street needs to be lit. To combat the feeling of insecurity, the integrated radio module anticipates the switching on of streetlights when a person moves by switching on the adjacent streetlights.
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 when switched 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 transmission 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 fuse box of the light point 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
The eDyn modules are programmed using a programmer connected by USB cable to a computer running Windows 10/11.
eDyn programmers are available to order from JDC Electronic SA.
Installing the software
Caution! Do not connect the USB cable until you have installed the software.
- Download the software from the Downloads section from here.
- Follow the instructions in the Readme1st.txt file to install it.
- Connect the programmer and select the appropriate serial port connection in the software.
Programming
Selecting the light point
When the program is launched, it is in listen mode and waits for a light point number to be received. 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 No." button again or enter the number manually in the "Detector No." field.
In a street, the "Wait for No." mode is very practical, because all you have to do is pass under a point of light and the number will be directly recognised.
Programming a light point number
Once a light point has been detected, it can be given a new number. This operation must be carried out carefully, as 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 "Programming number" 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 an identical number to two light points, as this would cause a communication problem.
Parameter management
The light point can be programmed at any time using the "Read parameters" and "Send parameters" buttons.
Luminaire parameters
All parameters can be set according to the graph below:
Radio communication parameters
The radio parameters can be modified according to the configuration for use in a street (spacing between luminaires, radio pollution, etc).
We recommend that you leave these options unchanged.
All the luminaires that are to interact with each other must be on the same channel. If it is decided to use channel B, the programming box must be switched to the "BOX channel" field when the programme is started.
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 useful addresses need be entered; any empty boxes will automatically be filled with address 0.
Test number
This tool simulates the detection of a light point and transmits 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.
