TV lighting [30]: At and around the television set, lighting should be variable. For reading or for working at a PC, the area around the screen should be illuminated by low-lumi-nance diffuse light. This reduces the bright-ness contrast between screen and back-ground and prevents early fatigue. Wall or table luminaires providing diffuse light behind or beside the television set create a relaxing, agreeable lighting atmosphere. There are also TV sets on the market with integrated background lighting. Important note: To rule out annoying reflections, care should be taken to ensure that light, e.g. from ceiling spots, is not directed at the screen.
