Lighting Distribution Pattern
Lighting Distribution Pattern
Outdoor light distribution patterns refer to the way light is emitted and spread across outdoor spaces by lighting fixtures. These patterns are designed to achieve specific lighting goals, such as illuminating pathways, enhancing security, or creating aesthetically pleasing environments. Several common outdoor light distribution patterns include:
| Distribution Type | Description |
|---|---|
| Type 1 | This distribution pattern provides a narrow beam of light with a high intensity directed in one direction. It is suitable for lighting narrow walkways, alleys, or roadways where light needs to be concentrated in a specific area without spillover. |
| Type 2 | Type II distribution emits light in a medium-width beam, offering a balance between width and distance. It is often used for lighting streets, parking lots, and intersections, providing adequate illumination both horizontally and vertically. |
| Type 3 | Type III distribution distributes light over a wide area, making it suitable for illuminating large open spaces such as parking lots, plazas, and recreational areas. It provides uniform illumination with a wide horizontal spread. |
| Type 4 | This distribution pattern projects light forward in a rectangular beam, making it ideal for lighting building facades, walls, and signs. It creates a uniform illumination pattern with greater distance coverage than width. |
| Type 5 | Type V distribution emits light evenly in all directions, creating a circular illumination pattern. It is commonly used for lighting areas such as roundabouts, courtyards, and pedestrian zones, providing uniform light distribution from all angles. |
