Beam angle

The beam angle or radiation angle specifies in which angle the light escapes from the lamp. This creates a cone of light that is larger or smaller depending on the angle. The following applies: Small beam angle (e.g. 38 °) for targeted lighting with narrow light cone, large beam angle (e.g. 120 °) for flat light with a wide cone. This is always measured in degrees (marked with °) and is usually given in the item description.

So pay attention to rooms where homogeneous, light light is needed to plan with a rather high beam angle. So e.g. kitchen or bath. So here we advise against standard installation spots. Rather flat light from 90 °, better 120 °. Make sure that you are not blinded.

The following applies:

10 ° for the lighting of certain objects such as a painting or a sculpture.
30 ° up to 60 ° for talent lighting for certain areas in the room, e.g. built -in spots.
90 ° for lighting narrow rooms such as corridors.
120 ° or more for the flat lighting of a complete room, with e.g. LED panels.
360 ° for light in all directions such as a light bulb.
The light intensity in the radiated cone is then different - the full brightness in the center, which decreases, the further you move outside. Everything in this cone of light, which is illuminated with a brightness of at least 50%, belongs to the beam angle, which is also called half -value angle. This means that the beam angle indicates which area is illuminated with a light force of at least 50%, i.e. very bright,. Everything outside of this area is only weakly illuminated and therefore no longer counts part of the beam angle, but belongs to the field angle.
