How To Choose Suitable Light Distribution Types I To V?

These distributions are used regularly in area lighting, floodlighting & roadway lighting, parking lot lighting, etc.

1. Understand the Light Distribution Types (I to V):

Type I: Provides a circular distribution, suitable for mounting at or near center of small roadways, walkways, and other similar applications.

Type II: Offers a rectangular distribution with a wider spread in one direction. Ideal for mounting at or near center of roadways, small parking lots, and general area lighting.

Type III: Provides a distribution in a forward-throwing, asymmetrical pattern. Suitable for roadways, general parking areas, and other areas requiring asymmetric lighting.

         T3M custom designed by BLX

Type IV: Offers a semicircular distribution that is ideal for mounting on the sides of buildings and walls, or areas where forward throw and lateral spread are both important.

       T4M custom designed by BLX

Type V: Provides a circular distribution that is nearly symmetrical in both horizontal and vertical planes. Suitable for mounting at or near ground level such as large parking lots, roadway intersections, and recreational fields.

2. Consider the Area Layout:

Assess whether the area is more square, rectangular, or irregular in shape.

Determine if the lighting needs to be focused more on the center, along the perimeter, or evenly spread across the entire area.

3. Evaluate Mounting Height:

Lower mounting heights typically require wider light distribution (Type V), while higher mounting heights can accommodate narrower distributions (Type II, III, IV).

4. Specific Lighting Requirements:

Consider factors such as required illumination levels (measured in lux or foot-candles), uniformity of lighting (how evenly light is distributed across the area), and glare control.

5. Regulatory and Design Standards:

Some areas may have specific standards or guidelines (like IESNA recommendations) for light distribution types based on the application and environment.

6. Simulation and Testing:

Use lighting simulation software to visualize how different light distributions will perform in your specific area.
