Human Centric Lighting

Human Centric Lighting (HCL) or Circadian Lighting is devoted to enhancing human performance, comfort, health and well being

Human Centric Light considers the three functions of light



Functional lighting prevents user discomfort while increasing eye comfort and facilitates users activities such as concentration and creativity


Biological lighting is sometimes referred to as circadian light and is designated to support the sleep-wake cycle of people


Emotional Lighting is the process of creating an environment which people see as comfortable and/or safe, give the user a representation of the time of the day and gives the user a good feeling

Additional techniques for a good human centric lighting design

Dark rooms

Don’t allow users to walk into dark rooms with no light. Walking into toilet or carparks without lighting can make occupants feel less safe.

 Well positioned sensors and standby lighting levels can ensure occupants are not walking into dark areas

Soft dimming

User comfort is affected when they are walking into areas where lights instantly turn on or off.

 The use of DALI dimmable drivers and lighting control can be used to control how the lighting reacts.

Adjacent spaces

Having unlit adjacent work areas can reduce the feeling of safety for some occupants.

 Use features like corridor hold or illuminate adjacent areas to a minimum levels to increase the wellbeing of employees.
