Trends in the lighting industry in all its aspects, digitalization of technologies for households and services in buildings, technology security. All of this was discussed at the largest international lighting industry trade fair, Light + Building 2024, which traditionally takes place in Frankfurt, Germany, and the Spectrasol team couldn’t miss it. Read a brief summary and the trends discussed at the event.
There is no doubt about the circadian effects of light
All major lighting manufacturers address its non-visual effects and offer full-spectrum lighting. There is no longer any doubt about the circadian and non-visual effects of light, its benefits, and the needs of the human body. A new area of interest is adding red energy in long wavelengths due to its regenerative and metabolic functions. Our lighting has contained this energy for a long time.
“In stimulating discussions, we agreed that the key and common task in this area is educating users and lighting technicians so that lighting with non-visual effects, similar to sunlight, is standardly applied in interiors where daily activities take place under artificial lighting,” explains Daniel Jesenský, Managing Director of Spectrasol.
He also adds that existing knowledge and products will fully move in this direction. At the same time, it will replace the original systems such as Tunable white and Human-centric lighting, which have not been successful on the market because they only change the color temperature (CCT) of light, which is unnatural for the body and does not work properly with the light spectrum composition. Users do not feel well under such lighting, and unnecessary control systems for daylight increase the cost of implementation.
Other trends worth mentioning
Another observed trend is the integration of acoustic elements combined with lighting fixtures. At the same time, two strong trends in light distribution are visible — the first and correct one is the use of large emitting surfaces of lights to imitate the natural sky indoors and improve visual comfort by reducing glare.
On the contrary, under the pressure of minimalist architectural trends, linear and spot lighting are emerging, emitting from unnaturally narrow and small surfaces. They are architecturally pleasing, but for users in offices and similar spaces, they are uncomfortable, impractical, and unsuitable for work. “This phenomenon confirms that the traditional paradigm of the common lighting industry still dominates. They provide what people are used to based on outdated but established approaches and information. But not what their body needs from light when they are unnaturally staying indoors all day, based on fully recognized information from chronobiologists and doctors,” comments Daniel Jesenský.
What is the view of the industry and users?
The traditional and inertia-driven lighting industry is still insufficiently concerned with the quality and properties of the light emitted by lighting fixtures. They are primarily interested in the design and construction of the light fixture, its lifespan, and energy efficiency. “These are certainly important topics, but fatally insufficient and often contradictory from the perspective of both the visual and biological needs of users,” adds Hynek Medřický, co-founder of Spectrasol.
The Spectrasol team at the trade fair: “We leave with the knowledge that we create our lighting at the highest global level. What we’ve been doing for many years is continuously blending into the mainstream of the lighting industry — such as large emitting surfaces, full spectrum and color rendering of emitted light, minimizing glare, and providing the best possible visual comfort. And all of this framed by our supreme goal, which is to bring artificial lighting as close as possible to natural sunlight.”
