How does good lighting affect our life? Under which kind of lighting, our work can be more efficient? Why we feel relaxed under sunset lighting? All these are related to our evolutionary biology, and Human-Centric Lighting(HCL) is using artificial light by intimating the natural light.
Today we would like to introduce you two kinds of Human Centric Lighting. Dim to warm and Tunable white.
Dim to warm, is a soft dimming lighting way like an incandescent to make our body at ease. The CCT range can be adjusted from 1800K-2700K/3000K, color temperature becomes warmer as you dim, from 3000K or 2700K to 1800K. And the lumen will change with the CCT changing, the lower the CCT, the lower the brightness.
Tunable white, is an LED system with a variable color temperature range from 2000K to 6500k. Which you can control the color temperature while maintaining the brightness. It quite suit some new constructions, it is 4 wires with 2 dimmers or DMX. For example, the hospital may want to have coller lighting during the day to help patients be more alert and warmer lighting at night to help them relax.
Human Centric Lighting can be beneficial in several ways, it can be good for health benefits, for your circadian rhythm and lighting. It can help increase the productivity by adjusting different color temperature. It can be sustainable and can design focus for us.
