Asymmetrical vs Symmetrical Lighting: What Engineers Should Know

Each type of floodlight has a different beam angle. To select a high-performance floodlight, it’s essential to understand the following:

Honestly, asymmetrical and symmetrical light distribution is the subject of great debate every time a project involves large-area new lighting installations. Keep reading this post to learn more about the advantages and different features of asymmetrical and symmetrical light distribution.

A Generalized Discussion: Asymmetric Lighting vs Symmetric Lighting (Light Distribution)

When discussing symmetrical light sources, keep in mind that they distribute light evenly in multiple directions. They’re apt for the general lighting design of places like storage facilities and open car parks. They’re also practical as accent lighting when performing visual tasks.

Asymmetrical lighting illuminates one direction compared to symmetrical lighting. For instance, it’s an effective LED lighting option for offices and other workplaces. The main reason is that the light spills from it and doesn’t produce direct glare.

Direct glare can cause protracted exposure, leading to severe eyestrain in the long run. Light distribution is a significant discussion concerning sports fields, car parks, streets, and workplaces. The light spill at your desk is worthy of notice if you want to ensure a comfortable work routine and avoid any eye strain or damage.

Let’s take a home reading light, for example. When you use one, it shouldn’t bother the people watching TV in the same room as you. Similarly, people living near a sports field don’t want to stay awake due to the unwanted bright light.

What Is Asymmetric Lighting?

It has integrated advanced optics and significantly lowers energy costs. Asymmetrical light and asymmetric fixtures are trendy for their lower indirect glare. Asymmetrical light is more suitable for spaces where you require a transition from light to dark spaces.

What Is Symmetric Lighting?

As discussed earlier, symmetric lighting refers to a light system that spreads light beams in various directions. It’s recommended for large outdoor spaces and as accent lighting. Symmetric lighting produces both direct and indirect glare.

The History of Asymmetrical Lighting

Here’s a brief overview of the history of asymmetrical lighting:

The first few fixtures were developed during the 1960s

The main purpose of it during early invention was to light up an entire plane equally

The first few asymmetric luminaires were installed on the illuminated plane’s edges

What are The Advantages of Asymmetric Light Beams?

The term asymmetric light output refers to a simple light system. The light beams are directed sideways to illuminate a specific area. So, here are a few benefits of such a lighting option:

Lighting a Specific Area

Light fixtures that carry asymmetric direct light beams have integrated advanced optics. It allows direct light beams to pour over a particular area.

The most common asymmetric fixtures include “reflectors,â€?aka “parabolic.â€?Since those fixtures reflect light off of mirror surfaces to concentrate the light beam, they help significantly lower energy costs compared to traditional fixtures.

Optimal Direct Light Spread (Light Beam Angle)

Light emission doesn’t waste since the light beam is concentrated in a specific direction in a particular area.

Fewer Light Sources

Since light emission doesn’t go to waste, manufacturers don’t need to add additional light sources. The light technology is efficient and eliminates the need for extra lighting.

Where Can I Use Symmetric Light?

Sports Field Lighting

It’s not difficult to understand where you can and can’t use symmetric lights. The light reflected from any surface can significantly impact the ongoing activity or purpose, depending on the type of lighting option you choose. So, here’s a small list of where you can and can’t use symmetric light output:

Large Open Spaces

These could be sports fields, streets, and car parks.

Building Sites

Construction sites must install appropriate lighting options for optimal productivity. Even if a single beam angle is set in an awkward position, it could increase the risk of injuries, financial damage, and more.

Storage Facilities

Storage facilities require thorough direct light output and distribution. Symmetrical light spilled inside a storage facility must illuminate all necessary surfaces and directions.

Open Car Parks

If you’re in a car park, check out the lighting. It’s most likely symmetrical floodlights.

Symmetric LED lighting is the way to go. However, asymmetric LED lighting is better if you want more control over light distribution and are willing to sacrifice a little brightness for energy savings.
