Why Does The Opening Angle Of Lighting Matter?
On 12, Mar 2014 | No Comments | In Lighting tips and advice, Technical tips | By Steven Roziers
The opening angle (also called angle of aperture or radiation angle) is the extent to which the light of a light source is spread. The opening angle is therefore expressed in terms of degrees. An opening angle is always measured on a light source, and not on the lighting fixture (the appliance in which the light source is installed). With LED lighting the opening angle is often directly expressed on the lighting fixture, since the light source is mostly fixed into the fixture. The opening angle you require mainly depends on the purpose the lighting needs to serve.
