Deepak Kumar Dubey, Research scholar at the Nano Organic Photonics Devices Lab, Dept. of Material Science & Engineering at the National Tsing Hua University, Taiwan presents their Blue hazardous free Candle light-style organic light emitting diode based lamp. Increasing studies report that blue light to possess a potential hazard to the retina of human eyes, secretion of melatonin and artworks. To devise a human and artwork-friendly light source and to also trigger a "Lighting Renaissance", they demonstrate here how to enable a quality, blue-hazard free general lighting source on basis of low color-temperature organic light emitting diodes. This blue-hazard free candlelight OLED desk lamp (2,000K) is made by the collaborative effort of National Tsing Hua University and WiseChip Semiconductor Inc. It is presumably 20 times safer in terms of retinal protection and 10 times better for melatonin generation as compared with the 5000K blue light-enriched white light. It is friendly to human eyes, physiologies, artifacts, ecosystems, the environment, and night skies, besides being free from UV, flickering and glare etc.
