Existing Roadway Lighting Upgrade
A roadway lighting retrofit normally requires consideration of the existing infrastructure rather than simply replacing fixtures.
For the Liège application, the LED upgrade was configured around:
Existing roadway infrastructure
Existing electrical conditions
Fixture mounting requirements
Roadway lighting layout
Required operating conditions
The objective was to replace the existing lighting equipment with a more efficient LED configuration while maintaining a suitable roadway lighting system.

Project Engineering Process
01 — Existing Lighting Assessment
The existing roadway lighting conditions are reviewed before finalizing the LED replacement configuration.
Typical information includes:
Existing fixture type
Existing wattage
Pole arrangement
Road geometry
Electrical conditions
Installation requirements
02 — Onsite Metering
Where required, onsite measurements can be conducted to establish the existing lighting condition.
The measured data can then be used as a reference for the replacement design.
03 — Lighting Design
LIKELITE supports roadway lighting design according to the project requirements.
The design considers:
Road geometry
Fixture position
Mounting conditions
Optical distribution
Electrical configuration
04 — DIALux Evo Simulation
DIALux Evo can be used to evaluate the proposed roadway lighting layout.
Additional engineering formats include:
LitePro DLX / AutoCAD / AGi32
Project-specific calculation results should be generated from actual roadway dimensions, pole height, pole spacing, installation angle and photometric files.
05 — Product Confirmation
The final product configuration is confirmed according to:
Electrical requirements
Optical requirements
Environmental conditions
Installation conditions
Project quantity
06 — Production & Supply
The confirmed specification is manufactured and supplied according to the project order.
Project Quantity: 5,500 Sets
Rated Power: 80W
07 — Installation
Installation is completed according to the approved project layout and installation requirements.
Project Energy Performance
27% Energy-Saving Improvement
The Liège roadway lighting upgrade reported:
27% Energy-Saving Improvement
Energy savings are affected by the actual project operating conditions, including:
Existing fixture wattage
Replacement wattage
Number of operating hours
Lighting schedules
Electrical system conditions
Control strategy
Therefore, the 27% figure is presented as the project reference result, rather than a universal guaranteed saving percentage for every roadway project.
For new Projects, LIKELITE can calculate the estimated energy-saving potential using the customer's existing lighting data.
European Compliance
The project product configuration includes the following compliance requirements:
CE
LVD 2014/35/EU
EMC 2014/30/EU
RoHS 2.0
2011/65/EU
ErP
Energy-related product requirements.
The final certificates and applicable compliance documents should be confirmed against the exact production model supplied for the project.
