Preventing Light Spillage with LED Spotlights

Compared to LED floodlights, LED spotlights emit a dense, powerful beam that is capable of reaching far distances. Because of this lighting characteristic, the fixtures can contribute to light spillage around the target area.

Light spillage refers to stray light beams that illuminate nearby areas outside of the target. It is important to control light pollution, as it can be a major source of disturbance for people and animals. In fact, the issue is so prevalent that local governments typically impose regulations to reduce light spillage in residential neighborhoods and commercial spaces.

Addressing Light Pollution with Shields

There are several ways to decrease light spillage, when using LED spotlights. One of the most effective methods include the application of light shields. Also known as cutoff fixtures, the grade of the shield dictates the amount of coverage. For example, a full-cutoff LED spotlight will not allow light beams to pass over 90 degrees. By comparison, a non-cutoff lamp provides full, 360-degree illumination.

Light diffusers can also help control stray light beams. Although such lighting accessories reduce the intensity of the fixture, the components do not ‘cut’ the natural formation and angle of the beam.

Color Temperature and Dimming

Some lighting techniques for reducing light pollution involves changing the characteristics of the LED light. Low color temperature LED spotlights are less prone to contributing to glare on shiny surfaces. This is particularly useful for units mounted on a pole (used for illumination in parking lots), typically pointed downwards.

For a straightforward approach to preventing light spillage, individuals may consider incorporating a dimmer with the LED spotlight. To automate this process, one could install a timer to set the dimmer on a high setting, during late night periods. Minimal dimming settings can be applied to the LED spotlight when transitioning from day to night and vice versa.
