People foremost is the basic of illumination

Nov 20, 2017

Architects and designers have long been studying how to improve our working environment, whether from safety, technology or functional design. Over the past few decades, we have seen explosive growth in technological innovation in the workplace, from PCs, mobile phones, the internet to lighting. These advances help people become more efficient. 

But what if we can add new core innovation to our work environment? In this way, we can improve the productivity of our employees while improving our efficiency. 

In lighting, we can think of architectural design in a new way to improve the experience of the workplace. Many of the emotions of people are related to architecture, and many of these emotions are caused by the effects of illumination on people. A dark, low light environment makes people feel dull and even cold. The hum and slight flicker of old fluorescent lamps have an effect on human attention and thus affect performance. The best space for lighting and the environment can inspire people's positive emotions. 

LED Lighting offers a more consistent and scalable lighting effect. LED energy efficiency is obvious, with flexibility and reliability, is now entering the building environment in almost all applications. 

Over the past more than 50 years, the use of dimming technology has been available in commercial space. In the past, dimming technology was expensive for most general lighting applications. Brightness can be changed by directly adjusting the power supply circuit of the luminaire. Although the LEDs can now be manipulated through the previous generation of controls, future control capabilities are embedded in the LED drive and use a digital protocol that communicates directly with the driver. 

To maximize the value of LED lighting is not only to adjust the intensity of the light, but also to adjust the color quality-including the associated color temperature (CCT) and color rendering. By controlling the intensity and color of light, illumination design can improve the staff's satisfaction and productivity in space. 


LED based lighting can control and regulate the associated color temperature (CCT), evoking specific human biological responses and behaviours in well-designed indoor environments. 

People-oriented lighting use of the scene 

People-oriented lighting (HCL) offers many potential advantages in offices and workspaces. What is now known is that the HCL has a visual advantage. 

What is now known is that the HCL has a visual advantage. Lighting improves space, changes the way the building perceives it, and provides a more comfortable and customizable atmosphere within the building. 

Medical institutions are using people-centred lighting, increasing the temperature of colder temperatures in the staff area, keeping employees vigilant during shifts, and using warm color temperature in patient rooms to keep patients comfortable while resting and recovering. The school also uses people-oriented lighting and makes students quiet or awake according to the time of day. In a commercialized working environment, the effect of appropriate illumination color temperature can make the office environment more natural and comfortable while increasing productivity. 

Just as ergonomic chairs and keyboards, people-oriented lighting helps businesses to have happier, healthier employees, and to work better with employees. 

Next steps in lighting control 

The introduction of the HCL into the building means the installation of adjustable-light fixtures and intelligent lighting controls that can drive strength and color temperature. One of the innovations that can be implemented in these controls is the modulation of equipment, which automatically synchronizes the lighting cycle of buildings through astronomical event times. This means that the building can match the exact illumination conditions outside the building according to the local precise latitude and longitude. An intelligent HCL system can be managed in the background without day-to-day adjustments, and the system will operate automatically and provide quality lighting. 

The HCL system is also an independent system. Of course, it is another dimension in a generalized lighting control system, using inductive sensors and photovoltaic cells to automatically adjust the light level and save energy. 

For those who consider adding the HCL system, there are some things in the current product ecosystem that need attention. 

The luminaire must work with the lighting control system without adding any complexity. Not all manufacturers can use this approach, and users will be unhappy if they don't use more complex systems or can't use them. Therefore, it is necessary to use the control system with the luminaire. 

In addition, using certain types of HCL systems, installation and programming can be complex and expensive. Control manufacturers can require custom software to achieve color temperature effects. In addition, most contractors may be unfamiliar with digital lighting protocols, such as Dali or DMX controls. 

The future is adjustable. 

Tunable light will soon become as common as dimming. The reality is that all light is not equal. As with other products or technologies, their quality is also different. People will start to encounter the HCL more, and soon expect to install the HCL in the room or working environment. 

This means that new buildings will soon require HLC in the design and specification phase. In addition, existing buildings must provide refurbishment opportunities. 

The ultimate goal of the facility lighting is to make people feel as comfortable as the lighting in the natural environment, while being able to simulate the external day and night turnover indoors. When manual adjustments are required, the system can be optimized and modified to accommodate specific tasks at hand.
