Lighting Angle And Light Distribution Design Techniques For High Mast Lighting

As a core component of large-area outdoor illumination, high mast lighting is widely deployed in settings such as public squares, sports stadiums, ports, and highways. The design of its lighting angles and light distribution directly determines the quality of illumination, energy efficiency, and user experience. A scientifically sound and rational design not only meets the site's specific illuminance requirements but also helps prevent light pollution and conserve energy. These are some very useful design tips that can be used in most outdoor spaces. Join Phoebus, the high mast lamp expert, to take a look at these tips.

1. Lighting Angle Design Techniques

When changing the angles of the lights, you need to think about how tall the high mast lighting poles are and how big the site is. "Light up only when you need to, and don't waste" is the main idea. This approach has two main parts:

- Picking the Right Angle Based on Height:

Most high mast lighting poles are between 15 and 30 meters tall. There is a direct relationship between the height of the mast and the angle of light needed, which makes sure that there are no "dead zones" (unlit areas) and full coverage.

- For heights of less than 20 meters

It's best to keep the angle of the light between 60° and 90°. This is good for lighting up small public squares and parking lots, for example, because it keeps light from spreading too much, which could make the area too dark.

- Medium-to-High Heights (Over 20 meters):

You can change the angle of the light from 90° to 120°. This setup works best in big places like big sports stadiums and ports when used with multi-angle light fixtures.

- Glare Control:

Change the vertical angle so that pedestrians don't have to look directly into the light. Also, adjust the angles based on how many people are walking around the area to find a balance between good lighting and comfort for the eyes.

2. Methods for Designing Light Distribution

Choosing the right light distribution curve for the site is the key to designing an effective light distribution system. This will also help reduce light pollution and energy use. Here are the specific things you should think about:

- Set standards for site illuminance:

Different places need different amounts of light, so don't use a "one-size-fits-all" or random design method.

- Situations Where High Uniformity Is Needed (like sports stadiums):

Choose a light distribution pattern that makes sure there is high uniformity so that shadows don't get in the way of what people are doing.

- Multi-functional Scenarios (like Municipal Squares):

They should be both useful and pretty, and the light should be soft and even to make the space feel better overall.

- Choose the Best Types of Distribution:

Choose light fixtures with "bat-wing" or rectangular light distribution patterns over others. These designs do a good job of controlling how light spreads, which cuts down on light pollution. They work better on long sites, like highways and port terminals, than on sites where the light spreads out in circles.

 

 

3. Important Things to Think About When Designing

- Avoid Angle Overlap:

When installing multiple high mast lighting poles, the illumination angles of adjacent fixtures must be staggered by 15°–30°. This prevents localized hotspots or areas of insufficient illumination, thereby ensuring overall lighting uniformity.

- Change Based on the Type of Light Source:

LED high mast lights have high luminous efficacy and strong directionality, which lets them spread light more evenly and use narrower beam angles. On the other hand, traditional sodium lamps have lower luminous efficacy and need wider beam angles to make up for this shortcoming.

- Adjust to the Environment:

In areas next to residential areas, it's important to lower the angle of the light and choose anti-glare light distribution patterns to keep residents from being disturbed while they sleep.
