Light is an important requirement for all the type of life on earth. The light intensity, timing, pattern and wavelength influences our circadian rhythm, these rhythms repeats approximately 24 hours of the day. Exposure to the natural sunlight will synchronize our body rhythms to 24 hours. Circadian disruption due to inappropriate exposure to light may lead to health risks like sleep disorders, breast cancer and heart disease. Many people spend their most of time in artificial lighting environment, where it is not possible to have dynamic light which will help to manage people’s performance, productivity and health when working throughout the day [2]. Hence there is a need of a light source which enables people to perform well and reduce health risks. The proposed work developed a new LED lighting solution called Human Centric Lighting. The solution controls the light level automatically throughout the day. The human centric light is developed using tunable white LED luminaire which has warm white (2700K) and cool white (6500K) LEDs. By changing the light output of luminaire between these two CCT levels with respect to the real time it is possible to achieve dynamic light to support our health [3]. The human centric lighting is intended to go beyond illumination. It is intentionally designed to promote person’s well- being, mood and health. The big advantage of human centric lighting is people feel more comfortable and their hormone production is much normal than in artificial light and therefore get better sleep and can live much happier.
