Light is recognized as a vital nutrient for the human body, akin to food and water. It serves as the most powerful zeitgeber—literally meaning 'time-giver'—that regulates the mammalian circadian system.
As work has evolved, many of us now spend most of our waking hours indoors. There’s a growing need for adaptable and empowering workspaces, and good lighting is important for keeping our bodies in sync with the natural light cycle.
Human-centric lighting is designed to enhance well-being, mood, and health. It can boost concentration, safety, and productivity in workplaces and educational settings.
Uplifting mood and maximizing energy levels
Improves concentration & energy levels leading to increased motivation
Right light distribution offering clearness of vision
High-performance lighting supporting the human biological clock
Right light levels enhancing the designed environment experience
Intelligent lighting solutions leading to a better environment
Light is perceived in the retina through three types of photoreceptors: cones, rods, and the recently discovered intrinsically photosensitive retinal ganglion cells (ipRGCs). These cells send signals to the master circadian pacemaker in the suprachiasmatic nuclei (SCN) of the hypothalamus. The neuronal and hormonal activities generated by the SCN help regulate the circadian rhythm, creating a strong link between light and our mind and body.

During the day, bright light with high colour temperatures can help kickstart your morning by reducing melatonin levels and boosting cortisol production. The "post-lunch dip," a period of decreased alertness that happens between 1 p.m. and 4 p.m., can be countered by using higher color temperatures and increased light levels to enhance alertness in the afternoon. As the workday winds down, transitioning to warm, comfortable lighting can promote melatonin production and set the stage for a restful night’s sleep.
People who regularly work night shifts are often at odds with their biological clocks and rhythms. Bright light at night can boost alertness and improve work efficiency. However, extended exposure to bluish-white light may significantly disrupt sleep cycles, leading to stress, fatigue, and other health problems. To address this, workspaces need to provide the right lighting conditions to support effective work while also promoting healthy sleep patterns. High colour temperatures (bluish light) and increased light levels are recommended at the start of the evening shift. Transitioning to lower light levels and warmer colour temperatures at the end of the night shift can help create a comfortable state of mind, making it easier to relax and sleep well.
How it Works?
All LED lighting luminaires and sensors are connected to a PoE switch, which is the only AC powered device in the entire system. The switch sends the power as well as the control signals through the DC powered CAT6 cables, which eliminates multiple cables and makes installation and maintenance easier and faster, initially and over a long period of time.
Best Suited for
New constructions (or deep retrofits) where the entire cabling is being done afresh, as well as the interconnections of multiple systems are required.
How it Works?
All LED lighting luminaires and sensors are connected to a DALI controller via 4 cables, of which 2 are for power and 2 are for controls. All the commands from the user are sent to the controller and then to the respective devices, ensuring reliable and fast communication. Integration with BMS and/or HVAC and smart features such as Human Centric Lighting can be provided with a specialized design.
Best Suited for
New or old constructions alike, where efficient and convenient lighting control from a singular point is paramount. Simplicity is preferred over the sophistication in such situations.
How it Works?
The existing AC cables can be used to power the wireless modules which sit inconspicuously on the fixtures and connect to an authorized mobile device to provide fast and instant operation on lighting devices, as well as the most intuitive method of automating the on/off/dimming of the light luminaires.
Best Suited for
Existing offices that are undergoing a renovation; or spaces where installing new wiring is extremely difficult or impossible; or for new spaces where the highest priority is to have the easiest method of operating the lighting system.
Moreover, it enhances mood and bodily functions, positively affecting depression and anxiety while aiding in recovery. Using it in workplaces where people spend most of their daytime brings multiple benefits.
