Roadway Lighting Requirements

Ordinary roadway lighting Projects often involve the replacement or modernization of existing road lighting systems while maintaining appropriate illumination for drivers, pedestrians and surrounding public areas.

A practical roadway lighting solution should consider:

• Road width and geometry

• Existing lighting infrastructure

• Required lighting level

• Pole position and mounting conditions

• Luminaire optical distribution

• Electrical supply

• Environmental conditions

• Surge protection

• Energy consumption

• Maintenance requirements

• Local compliance requirements

• Installation and commissioning

The correct luminaire should therefore be selected together with the lighting layout and electrical design.

100W LED Roadway Lighting Configuration

The reference solution uses a 100W LED Roadway Light designed for AC roadway lighting applications.

The configuration can be adapted according to roadway geometry, lighting requirements, mounting conditions and project specifications.

Roadway Lighting Design

A roadway lighting solution should begin with the actual road rather than a predefined wattage.

LIKELITE provides:

• Lighting and Circuitry Design

• Onsite Metering

• DIALux Evo Layout

• LitePro DLX Layout

• AutoCAD Layout

• AGi32 Layout

• Project Installation

The design process can establish the appropriate relationship between luminaire position, optical distribution and roadway coverage.

Where project information is available, lighting calculations can be developed before production and installation.

DIALux and Photometric Planning

Lighting simulation provides a practical engineering reference before installation.

LIKELITE can use DIALux Evo and LitePro DLX for roadway lighting layouts and calculations.

The design process can be used to review:

• Luminaire positioning

• Roadway coverage

• Light distribution

• Lighting uniformity

• Expected illumination

• Pole arrangement

• Roadway geometry

AutoCAD can be used for engineering drawings and layout documentation, while AGi32 can support additional lighting calculations and verification.

The actual lighting class, Lux, uniformity and other photometric results should always be established from the specific roadway design rather than assumed from the product datasheet.

120° Roadway Optical Distribution

The reference LED Roadway Light uses a 120° beam angle.

Optical distribution must be considered together with:

• Road width

• Pole height

• Pole spacing

• Roadway geometry

• Mounting angle

• Required lighting level

• Luminaire orientation

A wider beam does not automatically mean better roadway performance. The final configuration should be verified through photometric calculation.

This is why LIKELITE treats optical selection and lighting layout as connected engineering tasks.

150 lm/W High-Efficiency LED Configuration

The reference product is specified at 150 lm/W.

Combined with a 100W rated power configuration, the solution provides a high-efficiency LED platform for roadway modernization.

Energy performance should be evaluated at system level, including:

• Existing luminaire power

• New luminaire power

• Operating hours

• Lighting requirements

• Lighting layout

• Control strategy

• Maintenance conditions

The Naples reference configuration reported a 26% improvement in energy efficiency.

This figure should be understood as a project reference result rather than a universal saving guarantee for every roadway.

IP66 Outdoor Protection

Roadway luminaires operate continuously in outdoor environments and require suitable protection against environmental exposure.

The reference configuration uses IP66 protection.

The aluminum-alloy lamp body and ALU+PC material configuration provide a practical housing structure for outdoor roadway applications.

The specified operating temperature range is:

-20°C to 45°C

This configuration is intended for outdoor roadway applications where weather exposure and long operating periods must be considered during product selection.

10KV Surge Protection

Outdoor roadway lighting infrastructure can be exposed to electrical surges and transient conditions.

The reference luminaire includes 10KV surge protection.

Surge protection should be considered together with:

• Local electrical infrastructure

• Pole wiring

• Grounding

• Distribution equipment

• Regional environmental conditions

• Project electrical standards

For larger municipal roadway projects, the luminaire-level protection should be coordinated with the overall electrical protection strategy.

European Compliance Configuration

The Naples reference configuration includes:

• CE

• RoHS 2.0

• ErP

• WEEE

• CONAI

These documents can support product evaluation, procurement review and project documentation for European-market applications.

The exact documentation required for a specific project should be confirmed according to the destination country, procurement requirements and applicable regulations.

Roadway Energy Upgrade Strategy

A roadway lighting upgrade is not simply a wattage replacement.

LIKELITE's solution approach combines:

Efficient LED → Appropriate Optical Distribution → Lighting Simulation → Correct Installation → Electrical Protection → Project Commissioning

The objective is to achieve the required roadway lighting performance with an optimized energy and maintenance profile.

The Naples reference configuration provides a practical example using:

100W + 150 lm/W + CREE SMD3030 + IP66 + 10KV Surge + 5000K + Ra80

with a reported 26% energy efficiency improvement.

Installation and Commissioning

The engineering solution continues beyond product delivery.

Project installation can include:

• Luminaire mounting

• Electrical connection

• Circuit verification

• Mechanical fixing

• Luminaire orientation

• Cable inspection

• Night-time operation testing

• Lighting performance verification

• Commissioning

Installation should follow the approved project drawings and applicable local engineering requirements.

Roadway Lighting Solution for Municipal Buyers

For municipalities and public infrastructure owners, the key considerations are usually not limited to product price.

A complete roadway lighting solution should provide:

Technical Fit

The luminaire matches the required electrical, optical and environmental conditions.

Engineering Fit

The product can be incorporated into the actual roadway lighting design.

Procurement Fit

Technical documentation and compliance information are available for evaluation.

Installation Fit

The product can be deployed consistently across the project.

Lifecycle Fit

This approach is particularly relevant for large municipal roadway upgrades and infrastructure replacement programs.

Roadway Lighting Solution for EPC Contractors

EPC contractors often need a lighting supplier that can participate beyond the quotation stage.

LIKELITE's engineering support can be integrated into an EPC workflow:

Project Drawings → Site Data → Lighting Calculation → Product Selection → Technical Submittal → Approval → Production → Delivery → Installation

The objective is to reduce the gap between product procurement and engineering implementation.

Roadway Lighting Solution for Bulk Project Buyers
