Revolutionizing Human Centric Lighting Design with Casambi Control System and SunLike Technology

Revolutionizing Human Centric Lighting Design with Casambi Control System and SunLike Technology

SunLike Human Centric lighting via Casambi app

Casambi, a pioneer in Bluetooth Low Energy (BLE) wireless lighting control, has teamed up with LED technology specialist Seoul Semiconductor to offer lighting designers precise control of LED strips, modules and luminaires that use the new SunLike technology that matches the spectrum of sunlight. For the first time, this development puts true human-centered lighting in the hands of designers.

Users can use Casambi's Bluetooth-based wireless control system and app with products that include SunLike series LEDs to precisely adjust the light level, knowing that the spectrum reflects real sunlight, a key ingredient for Human-centric lighting

Human-centric lighting describes lighting designed to work with the natural rhythms of the human body. It is based on the well-known fact that the human eye recognizes the presence of a certain wavelength of blue light in the spectrum of sunlight and derives the time of day from this. In this way, light helps to regulate our sleep-wake cycles and other physical rhythms and has a significant impact on our mood and well-being.

Human-centered lighting takes advantage of this effect by adjusting its brightness and color temperature during the day to mimic natural light.

With Casambi you can now set the color temperature at specific hours of the dayCasambi allows control of the lights through a timer or a variety of presence/movement sensors and daylight sensors. It can control lights that change colour temperature over a very wide range, and designers have the freedom to configure dimming and create scenes or animations for the application.

The Comprehensive Guide to Choosing the Right Color Temperature for LED Lighting

White LED light color temperature can be from 2000K to 10000K

Natural light is a beautiful and dynamic source of white light, with its tone and brightness changing throughout the day and the seasons. The tone of white light is called color temperature, which is measured in degrees Kelvin (K). The color temperature of natural light changes during the day, from a warm orange-red hue of about 2000K at sunrise and sunset to a cooler blue-white hue of about 5500-6500K at noon. In the shade, the color temperature can even reach up to 8000-10000K, which is an extremely cool blue-white hue.

Artificial light sources are available with all relevant color temperatures of sunlight. Some traditional light sources, such as incandescent lamps, can only be manufactured with a fixed color temperature of 2700K. However, with the advancements in LED lighting technology, we now have access to LED light sources that can be produced with a wide range of color temperatures, from 2000K to 10000K, with the most common color temperatures falling within the 2700K to 6500K range.

One of the key benefits of LED lighting is the ability to produce light at a specific color temperature, which can help create the desired mood or atmosphere in a space. LED lights with warm color temperatures, such as 2700K, can provide a cozy and relaxing atmosphere, making them great for use in living rooms, bedrooms, and other spaces where a sense of comfort is desired. Cooler white LED lights, with color temperatures in the 5000K to 6500K range, can help create a more energizing and focused atmosphere, making them ideal for use in offices, factories, and other workspaces.

An important factor to consider when selecting LED lighting color temperatures is the psychological and physiological effects of light on people. The color temperature of light can affect mood, energy levels, and even sleep patterns. Warm white light with a color temperature of 2700K to 3000K can have a calming effect on the body, making it a great option for spaces where relaxation is a priority, such as bedrooms or living rooms. Cooler white light with a color temperature of 5000K to 6500K can have an energizing effect, making it ideal for workspaces, such as offices or factories.

Advantages of LED Cove Lighting

LED cove lights are a versatile and energy-efficient lighting solution suitable for a wide range of interior spaces, including living rooms, bedrooms, kitchens, lobbies, restaurants, and retail spaces. The flexibility in design is one of the significant benefits of LED cove lights, as they can be installed in various shapes, sizes, and colors. This allows for endless possibilities in creating unique and captivating lighting designs that can be customized to meet individual preferences. LED cove lights also come with dimming capabilities, which allow for greater control over the intensity and mood of the light.

Another significant advantage of LED cove lights is their energy efficiency. Compared to traditional lighting sources such as incandescent or fluorescent bulbs, LED lights consume less energy and have a longer lifespan. This not only reduces energy costs but also lowers the environmental impact of the lighting system.

Factors to Consider for Cove Lighting Installation

Several factors need to be considered when installing LED cove lights, such as the location of the cove, the type of LED strips to use, and the color temperature of the light. Working with a professional lighting designer or electrician can ensure that the installation is done correctly and efficiently

Achieving Effective Germicidal Action with UVC Radiation: A Comprehensive Guide

Fluence (UV Dose) Required for up to 99% disinfection from Viruses, Bacteria

The information below is extracted from the research paper: "Fluence (UV Dose) Required for up to 99% disinfection from Viruses, Bacteria, Protozoa and Algae"  that can be downloaded also on our website at the links below:

PDF: Fluence (UV Dose) Required to Achieve Incremental Log Inactivation of Bacteria, Protozoa, Viruses and Algae

Germicidal action of UV radiation

The effectiveness of sterilization or disinfection with UV light depends on the exposuretimewavelength and irradiance.

  • Exposure or fluence (sometimes called dose) is measured in mJ/cm2 (where 1 mJ/cm2 = 10 J/m2)
  • Exposure time is measured in seconds (s), minutes (m) or hours (h)
  • Irradiance is the flux of radiant energy per unit area, in other words how much of the UV radiation power (measured in W = 1000 “miliwatts” mW = 1.000.000,00 “microwatts” μW ) reaches the surface. Irradiance is measured in mW/cmor W/m2 (1 mW/cm2 = 10 W/m2) and is dependent on the radiant power, distance and dispersion of the radiation emitted by the lamp source.

Many studies that show the effectiveness of UV light in disinfection or sterilization present in their findings the inactivation of virus or bacteria for a given Exposure in an amount of time, for a given UV wavelength. However, it is difficult to centralize or build a database with so many variables. The most common solution to this problem is to present the fluence required to achieve a log reduction from 1 to 5.

 Log reduction explained

"Log reduction" is a mathematical term (as is "log increase") used to show the relative number of live microbes eliminated from a surface by disinfecting.  For example, a "5-log reduction" means lowering the number of microorganisms by 100,000-fold, that is, if a surface has 100,000 pathogenic microbes on it, a 5-log reduction would reduce the number of microorganisms to one, equal to 99.999% kill rate.

Log Reductions from 1 to 5 are the most common in research papers about UV light disinfection. Their meaning:
  • 1 log reduction means the number of germs is 10 times smaller (101)
  • 2 log reduction means the number of germs is 100 times smaller (102)
  • 3 log reduction means the number of germs is 1000 times smaller(103)
  • 4 log reduction means the number of germs is 10,000 times smaller(104)
  • 5 log reduction means the number of germs is 100,000 times smaller(105)
