Each asymmetric light distribution is different!

With the rapid development of the range of available optical devices for LED, floodlighting has made significant progress. The different optical systems available now help to complex shape the distribution of light to guide it in the correct direction.

Universal LED floodlights are easy to obtain and are well-known. They typically have a wide beam (typically in the range of 100-120 degrees) of light distribution and have been widely used in numerous outdoor lighting applications. However, LED floodlighting has gradually emerged with asymmetric distribution of floodlights, catering to general areas, parking lots, and sports lighting. Some commonly used terms for them are asymmetry, double asymmetry, forward casting, directional forward, etc. Generally speaking, asymmetric floodlights mainly emit light in the forward direction when not tilted (with the front cover or emitting surface parallel to the ground), rather than in the forward direction. More uniform distribution in all directions than wide beam light.

Compared to general wide beam floodlights, asymmetric floodlights have many advantages:

– Effectively utilize light output. Using a tilted regular floodlight may result in a significant loss of light and direct shooting into the sky

Reducing the amount of light emitted into adjacent residential properties can help comply with the laws and regulations of some countries

Compared to general floodlights that may require high tilt angles, they typically do not require tilting or very small tilting. Due to a complete and direct view of the luminescent surface, this may cause discomfort and glare during viewing.

Compared to the widely used wide beam floodlights, the emergence of asymmetric floodlights has gradually gained people’s favor, which is indeed a positive development. However, there are several considerations. Asymmetric floodlights have different peak intensity angles. This is the angle at which the peak intensity of the asymmetric beam is aimed. The peak intensity angle may vary from 30 degrees to 60 degrees. Generally speaking, this determines the distance ahead that the light can cover.

The difference between asymmetric floodlights lies in the narrowness or width of the asymmetric beam. These two factors greatly affect uniformity, lighting levels, illuminated areas, effectiveness in meeting Australian lighting standards, spill control, and optimal installation height.

These factors also determine the effectiveness of specific asymmetric floodlights in different applications, such as large sports fields, small sports areas, industrial stands, and parking lots. Some asymmetric beam distributions may be more suitable for specific applications than other beam distributions.

If you need more information about different aspects of asymmetric floodlights, or have any questions about their technical aspects, use in specific applications, or lighting simulations using them, please feel free to contact us at any time. DNS Lighting provides a variety of asymmetric floodlights with various types of asymmetric distribution, which can meet a wide range of application needs.
