Shielding angle

What always needs to be avoided with lamps is a glare due to excessive lights. Among other things, this can occur if the so -called shielding angle is not right. To prevent this, lamps have housing parts, slats or grids that shield the light. In addition, superiors can help opal or prismatic covers as well as the so-called intellectual reflector technology. A shield angle gives information about the visual comfort of a lamp.

It is the angle between a horizontal and a vertical that runs from the edge of the lamp to the edge of the lamp. If this shielding angle is not correct, this can lead to a direct fading.

For the lighting at the workplace, a shielding angle with reference to the horizontal level according to DIN EN 12464-1 is defined, since detailed and precise tasks often have to be done when working, in which a glare would be fatal.

The shielding angle indicates in which area the light of a lamp is visible to the viewer. A larger shielding angle means that the light is less visible to the viewer, which reduces glare effects and undesirable reflections. If the shielding angle is too tight, a direct blinding can arise and the lamp is visible within the shielding angle, which reduces visual comfort.
