Human Centric Lighting

Human Centric Lighting is created by changing colour and intensity of white light, and designing lighting to support the end-users' lighting needs.

The natural circadian rhythm of a person can be supported by using warmer (relaxing) light with lower intensity in the morning and evenings, and cooler (energising) light during a typical working day.

Lighting can also be tuned during the day to support more temporary needs. We can use warmer white light with slightly lower intensity, to help users calm down when facing high stress. Or we can use cooler white light with higher intensity, to help users energise e.g. on early morning.

LIGHTING MANAGEMENT SOLUTIONS

For maximised well-being and efficiency, optimal lighting should be delivered at the right place and at the right time. To precisely control and design lighting environment, you need ability to freely adjust colour temperatures and illuminances. Helvar's networked lighting management solution with iC is a highly advanced and flexible solution that allows you to design your lighting environment exactly as you like it.

 

iC Networked Solution

The iC Networked Solution is based on Helvar's well known lighting management solution with Routers (Imagine 920 Router) and Designer iC Software. This future proof and scalable solution is now fully compatible with the DALI colour control standard. With the Designer iC, it is easy to pick the right colour for each luminaire within the lighting network. This makes the commissioning of the system much faster.

Helvar continuously works on adding new functionalities and control options. Lately the colour control support was added to uSee, an easy to use, web based visualisation tool used to monitor and control Helvar’s router based systems. Also Helvar’s range of user interfaces including button, sliders and rotary controls now provide advanced colour control functionality.

 


 

STANDALONE SOLUTIONS

Helvar iC standalone solutions are easy to implement as a single luminaire or as a single room solution. Natural colour temperature and illuminance of daylight varies greatly, influenced by location, time, weather, etc. With the iC standalone solutions, it is possible to simulate the natural outdoor lighting environment.

Helvar also offers other standalone solutions. In the Dynamic Weather Solution, the iC Dynamic driver can be pre-programmed to change the luminaire colour temperature naturally by providing an indoor environment which generates more natural light. This can be achieved without any configuration or on-site control. Using Helvar iC drivers, it is also possible to implement Tunable White using the swich-control functionality which requires less cabling.

The iC standalone solutions provide a simple way to implement Tunable White solutions. Helvar continues to develop a new easy to control, standalone solution in the coming months.

 


 

LUMINAIRE COMPONENTS

Helvar iC DALI drivers and LED modules are the heart of the tunable white luminaires, developed specifically for dimming and tuning the white colour. The two driver output channels are connected to two modules with different colour temperatures, warm white and cool white allowing easier control of the colour temperature.

iC DALI Drivers: In the iC drivers, LL35/2-E-DA-iC (35 W) and LL60/2-E-DA-iC (60 W), the total power can be divided between the two output channels in any proportion. The current output can be set between 350 mA and 700 mA, with a current setting resistor.

iC LED Module: The L-iC-282 LED module has two individual LED channels that provide a dynamic colour temperature range from 2700 K to 6500 K when operated with a Tunable White LED driver.
