Title: LED Lighting for Health – Status Quo or Dreams of the Future?

Abstract: Contemporary artificial light sources such as LEDs offer low energy consumption, extended life cycles and optimal integration into digital light control systems. On the other hand, LED for general lighting purposes exhibit a spectral energy distribution and other properties which are far apart from natural light sources and lighting conditions. The dissection of the full spectrum found in non-thermal light sources may turn out to be problematic with regard to the coordinated light sensing via ocular, dermal end cellular light perception pathways in humans. Possible endocrine, visual and chronobiological effects of non-thermal light sources are discussed and proposals for spectral properties of bio-compatible light sources are provided.
