  • a central aspect in the lighting technology concerns the question of how the light emission of bulbs can be made such that the dazzling of people who are in the illuminated area is avoided. This concerns in particular the lighting of workplaces, since there are circumstances in which persons are permanently located within the illuminated area over a relatively long period of time. If glare would occur, it could be extremely annoying and negatively affect the work performance. However, the same applies to the lighting of areas in which a large number of people may reside, such as.
  • Light emission occurs primarily downwards and in particular a light output above certain angles to the vertical is avoided.
  • Such a light emission which is also described in corresponding standards, prevents observers from observing the luminous surface of a luminaire at very shallow angles. Since there is a very high so-called luminance especially at these angles, this measure helps to avoid dazzling. Also, a light output directed towards the underside avoids disturbing reflections on vertical surfaces such as screens or the like.

If, in addition, other illuminants are available which illuminate the area in which the recognized person is located from another - not dazzling - direction, then they can be selectively increased in their brightness if necessary in order to continue to provide shadowless illumination of the entire area Range.

These LEDs 115 are now designed in such a way that they do not each have the same light emission characteristic and, accordingly, in each case illuminate the substantially identical area as a whole.

If, in the context of the image analysis, it is found that a person is looking in the direction of the camera, this means in the present case at the same time that the person in Direction of the bulb 110 views and would be blinded accordingly.

In the illustrated embodiment in Figure 1 this is the case for the first person 50i, the person 50 2, however, looks in a direction away from the lighting means direction, so that here there is no danger of blinding.
