152° × 150° ultra-wide beam angle for more uniform road lighting

2026-05-13

Why is TYPE 5 lighting—which offers“wide coverage, high uniformity, and high comfort”necessary for main road lighting?

In modern urban street lighting, “brightness” is no longer the only criterion. Truly excellent street lighting places greater emphasis on lighting uniformity, coverage, and visual comfort for drivers.

In particular, on major urban thoroughfares, expressways, industrial park roads, and large parking areas, if the light distribution of the fixtures is improper, the following issues are likely to arise:

  • Uneven road illumination

  • Bright in the middle, dark on the sides

  • Dark spots between lights

  • Driver eye strain

  • Forced to increase the number of lights to compensate for the lack of brightness

And this is precisely the purpose of the TYPE5 road lighting distribution.

What is the Type 5 light distribution for street lighting?

The Type 5 light distribution is a typical wide-angle symmetrical distribution used in road lighting. Compared to traditional road light distributions that tend to project light to one side, the most distinctive feature of Type 5 is:

1.Wider coverage

The TYPE5 light distribution provides uniform illumination over a wider area around the fixture, making it particularly suitable for:

  • City Intersection

  • Large parking lot

  • Park Roads

  • Square Road

  • Shared-use path

  • Two-way multi-lane road

It not only illuminates the central area of the road, but also covers the roadside, pedestrian areas and corners.

2.Greater uniformity

Uniformity is a key indicator of the comfort of road lighting.

The higher the uniformity:

  • The smaller the variation in road surface brightness

  • More comfortable for the driver

  • Improved night vision

  • Greater road safety

Excellent TYPE5 light distribution effectively reduces “hot spots” and “dark areas,” resulting in a more natural and even illumination along the entire road.

3.Better suited for wide-spaced lighting

With traditional light distribution, illuminance gaps are likely to occur when lamp posts are spaced far apart.

Because the TYPE5 light distribution pattern covers a wider area, it can achieve:

  • Wider spacing between light poles

  • Fewer luminaires

  • Lower project costs

  • Higher overall lighting efficiency

This is also a key reason why an increasing number of municipal projects are choosing the TYPE5 light distribution.

Herculux New Matrix Series

In response to the demand for “wide-area, high-uniformity” lighting in modern roadways, Herculux has launched the all-new Matrix Series TYPE5 road lighting distribution solution.

Key Specifications

  • Beam angle: 152° × 150°

  • Luminaire efficiency: 93%

  • Light type: TYPE5 (T5)

  • Compatible light source: 5050 LED

  • Aspect ratio: 3:1

  • Uniformity: 0.74

Exceptional uniformity, perfectly illuminating intersections

Why is this light distribution pattern superior?

Extremely wide coverage

The wide-angle design (152° × 150°) allows the light to cover a broader area of the road. Even with wider spacing between light poles, consistent illumination is maintained.

This means:

  • Fewer light fixtures

  • Lower installation costs

  • Higher space utilization

At the same time, it ensures that the brightness of the road remains consistent.

Uniformity as high as 0.74

In road lighting, uniformity often determines the final visual experience. Herculux New Matrix Series achieves a high uniformity of 0.74, effectively reducing:

  • Contrast between light and dark

  • Dark spots on the road

  • A sense of visual oppression

Making nighttime driving safer, more comfortable, and easier on the eyes.

93% luminaire efficiency making every beam of light more valuable

High efficiency means less light loss. The Herculux Matrix series of luminaires achieves an efficiency of 93%, ensuring that more light is directed toward the target area rather than wasted in unused spaces.

The benefits include:

  • Greater energy efficiency

  • Lower energy consumption

  • More stable illuminance output

  • Improved Energy Efficiency of the Project

Stay tuned for more in the Matrix series

Herculux will continue to focus on optical design for road lighting and develop a wider range of matrix-series light distribution solutions tailored to various applications.

In the future, we will:

  • Greater uniformity

  • More precise light control

  • Lower energy consumption

  • Suitable for a wider range of applications

Stay tuned for more Matrix Series light distribution options.
