The light distribution curve of a car park LED linear fixture plays a critical role in determining how the light is dispersed across the parking area. It provides valuable information about the fixture’s illumination pattern, intensity, and uniformity, helping to optimize visibility and safety. In this article, we will explore what the light distribution curve of a car park LED linear fixture is and why it matters.

The term “light distribution curve” refers to a graphical representation that illustrates how light is emitted from the car park LED linear fixture in different directions. This curve gives us a visual understanding of how the light spreads horizontally and vertically, providing valuable insights for lighting designers, architects, and facility managers.

The primary objective of the light distribution curve is to ensure adequate lighting levels throughout the car park while minimizing energy wastage and light pollution. By analyzing this curve, professionals can determine the optimal placement and configuration of fixtures to achieve desired lighting performance.

Each of these zones in the light distribution curve plays a crucial role in ensuring not only the functionality but also the aesthetic appeal and safety of a car park environment. Let’s delve deeper into each aspect:

Forward Throw

This zone is pivotal for areas where intense, targeted lighting is crucial, such as near entry and exit points, payment kiosks, or areas with high foot traffic. The focused beam minimizes light spillage, ensuring energy efficiency while maximizing visibility exactly where it’s needed. This focused lighting encourages safe navigation and surveillance, deterring potential criminal activities due to the heightened visibility.

Wide Light Distribution

The wide light distribution zone is designed to create a balanced and evenly lit environment across broader spaces within the car park. By minimizing harsh shadows and dark corners, it promotes a sense of safety and ease of movement for vehicles and pedestrians alike. This zone is particularly critical in aisles between parking stalls, where clear visibility reduces the risk of accidents and increases user comfort.

Backlight lighting

Although not primarily for illumination, the backlight zone serves multiple secondary purposes. It can aesthetically enhance the car park’s appearance, especially when combined with architectural features or landscaping. Additionally, it can serve as a safety feature by making the fixture more visible from all directions, which is especially beneficial in emergency situations or for wayfinding. Backlighting can also help create a less oppressive atmosphere by breaking up the monotony of downward-only lighting.


Uplighting contributes to the ambiance and visual comfort of outdoor car parks. It softly illuminates the ceiling or upper parts of the structure, reducing the stark contrast between bright ground areas and dark skies, which can cause eye strain and disorientation. This effect not only improves the overall look of the car park but can also make the space feel more open and inviting, encouraging a sense of security for users.

Glare Control

Effective glare control is paramount in any lighting design, and car parks are no exception. Uncontrolled glare can lead to temporary blindness, reduced visibility, and increased accident risks. Strategies like using lenses or louvers to direct light, selecting appropriate beam angles, and positioning fixtures carefully are employed to minimize direct glare. The light distribution curve aids in identifying and mitigating such issues during the design phase, ensuring that the final installation provides comfortable, safe lighting without compromising on brightness or efficiency.

Understanding the light distribution curve of car park LED linear fixtures is crucial for achieving optimal lighting outcomes. By carefully selecting fixtures with suitable beam angles, designers can ensure that lighting is spread evenly and efficiently across the parking area, minimizing dark spots and maximizing visibility.

The light distribution curve allows professionals to evaluate the uniformity of lighting, ensuring that all areas of the car park receive adequate illumination. Consistent lighting levels contribute to a safer environment, allowing drivers to navigate easily, read signage, and identify potential obstacles.


The light distribution curve of a car park LED linear fixture provides valuable insights into how light is emitted and distributed across the parking area. By analyzing and understanding this curve, lighting designers can make informed decisions regarding fixture placement, beam angles, and glare control, ultimately leading to enhanced visibility, improved safety, and energy-efficient lighting solutions. When selecting car park LED linear fixtures, it is essential to consult manufacturers’ specifications and work with experienced professionals to ensure the desired lighting objectives are met.



Why Choose LED Linear Fixtures for Parking Lot Lighting?

LED linear fixtures are chosen for parking lot lighting primarily because of their high energy efficiency, long lifespan, and low maintenance costs. Their linear design allows for flexible adaptation to different parking space layouts. Additionally, the color temperature and brightness of LED fixtures are adjustable, providing better visual experiences tailored to specific needs.

What are the Common Control Methods for LED Linear Fixtures?

Common control methods for LED linear fixtures include switch control, dimming control, and smart control. Switch control is straightforward and suitable for fixed lighting scenarios. Dimming control allows adjustment of brightness to meet different lighting requirements at various times or occasions. Smart control, on the other hand, enables remote control and automatic adjustment via smartphone apps, sensors, etc., enhancing the intelligence level of lighting.

How is the Luminous Efficacy and Uniformity of LED Linear Fixtures Ensured for Parking Lots?

Parking lot lighting necessitates uniformly distributed light to ensure good visibility in every corner, reducing shadows and glare. LED linear fixtures achieve uniform illumination and high luminous efficacy through precise optical design, such as using professional lenses or reflectors and arranging fixture spacing reasonably.

What are the Installation Methods for LED Linear Fixtures and How to Choose the Most Suitable for Parking Lots?

LED linear fixtures for parking lots can be installed using different methods such as pendant mounting, wall mounting, or recessed installation. When selecting the installation method, factors such as the ceiling structure, maintenance convenience, and budget need to be considered. For instance, pendant mounting is suitable for high-ceiling spaces, facilitating maintenance, while recessed installation offers a more aesthetic and concealed option, ideal for new facilities.
