Type I distribution is great for lighting walkways, paths, and sidewalks. This type of lighting is meant to be placed near the center of the pathway. This provides adequate lighting for smaller pathways.
T1 Light Distribution Shape
Pattern Type I is a two-way lateral distribution having a preferred lateral width of 15 degrees in the cone of maximum candlepower. Therefore, the two principal light concentrations are in opposite directions along a roadway. And this type is generally applicable to a luminaire location near the center of a roadway where the mounting height is approximately equal to the roadway width.
T1 Light Distribution Application
In addition, you can observe the longitudinal and symmetrical lighting for streets. And the bi-directional illuminance is uniformity distributed across the two sides of the light pole. Therefore, we need relatively lower power, ranging from 30W, 40W, 50Wor 60W LED lights to light up this area.
