• Motorways

• Highways

• Expressways

• Interurban roads

• Urban expressways

• Road junctions

• Interchanges

• Bridges

• Road infrastructure

Highway Lighting Solution Overview

Highway Lighting Challenges

Highway lighting systems are normally exposed to continuous operation, weather conditions, electrical fluctuations and large installation areas.

A highway lighting upgrade may need to address:

Existing Lighting Infrastructure

Existing poles, mounting positions, circuits and fixture quantities need to be considered before replacement.

Optical Distribution

The beam distribution must match the road layout and fixture mounting arrangement.

Electrical Conditions

Input voltage, circuit configuration, power factor and surge protection are important for highway applications.

Environmental Exposure

Outdoor highway fixtures must be designed for rain, dust and changing environmental conditions.

Maintenance

Fixture reliability and accessibility directly affect the long-term maintenance requirements of a highway lighting system.

Energy Consumption

Replacing inefficient conventional fixtures with high-efficiency LED fixtures can reduce electrical consumption when the new system is properly designed and operated.

LIKELITE Highway Lighting Approach

1. Existing Roadway Assessment

LIKELITE can review existing highway lighting conditions before final fixture selection.

Typical project information includes:

• Road layout

• Road width

• Number of lanes

• Pole locations

• Pole spacing

• Mounting height

• Existing fixture type

• Existing fixture wattage

• Existing lighting quantity

• Electrical supply

• Operating schedule

For retrofit projects, this information provides the basis for the replacement design.

2. Onsite Metering

For projects requiring field verification, LIKELITE provides Onsite Metering support.

The assessment may include:

• Existing illumination

• Lighting distribution

• Dark areas

• Existing fixture performance

• Roadway lighting conditions

• Electrical information

The exact measurement scope is determined according to the project requirements.

Highway Lighting Design

Lighting & Circuitry Design

Highway lighting is designed as a complete system rather than a standalone product purchase.

LIKELITE's engineering workflow considers:

This allows the LED Highway Light configuration to be evaluated within the actual roadway environment.

DIALux Highway Lighting Simulation

LIKELITE supports professional lighting layout and simulation for highway lighting applications.

Available design tools include:

• DIALux Evo

• LitePro DLX

• AutoCAD

• AGi32

The lighting simulation can be used to evaluate the proposed fixture arrangement before installation.

Depending on project requirements, the design can assess:

• Illuminance

• Uniformity

• Lighting distribution

• Fixture positioning

• Pole spacing

• Roadway coverage

• Mounting configuration

Actual calculation results depend on the project road geometry, mounting height, pole spacing, photometric data and required lighting criteria.
