NettetLux is used to determine the intensity of the light over an illuminated area, to be specific; 1 lux equals 1 lumen pr. m 2. A flashlight or headlamp cannot be marketed with a specific amount of lux, because it depends on how far away the light source is and the angle of the light beam. Lux can be measured using a lux meter. Nettet9. mar. 2024 · Beam angle is precisely the angle made between two vectors from source to the projection surface on the points where the intensity reduces to half on both sides.So, it is fixed for a given LED. Viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance.
