Khabarovsk Novy Airport
Objective
In the new terminal of the airport, it was necessary to close all issues of design lighting, taking into account both the appearance and the required level of illumination. To develop from scratch the project of the unique main light composition of the atrium "Waves of the Amur River".Solution
The most difficult task in the solution was the light structure of the atrium. Due to the impossibility of assembling elements from parts at a height of more than 15 meters, we had to create a light, reliable seamless structure, assemble it and only then lift and fix it at the design mark. The dimensions of the elements were from 12 to 50 meters, and the weight was from 100 to 700 kg.Also for lighting solutions, according to the design project, DELTA luminaires of various sizes were developed, more than 1000 meters of linear light systems were manufactured and installed.
Result: The final appearance of the object clearly corresponds to the project of German architects. The light structure, visible through the glass façade, has become an integral part of the overall look. The Lighttech team has once again created a unique thing in the world!
Location: Khabarovsk, Russia
Lighting technology
Lighting technology is an applied field of science and engineering dealing with the generation, spatial redistribution, measurement and practical use of optical radiation. For a long time its role was limited to providing visibility at night, but modern lighting technology has grown into a complex interdisciplinary industry at the intersection of optics, materials science, microelectronics, architecture and neurobiology.
The fundamental turning point in the industry was the solid-state revolution — the transition to semiconductor light sources (LED). LEDs displaced traditional incandescent lamps and gas-discharge tubes thanks to phenomenal energy efficiency, miniature size, longevity (tens of thousands of operating hours) and high resistance to mechanical damage. This made it possible to abandon bulky luminaires in favour of integrated architectural solutions, concealed lighting and ultra-thin optical systems based on secondary optics (lenses, collimators and microprismatic diffusers).
The approach to light quality has changed in parallel. Where luminous efficacy (lumens per watt) used to be the main criterion, the focus has now shifted to colour rendering (CRI and TM-30 indices) and visual comfort. The suppression of parasitic flicker and control of the discomfort glare index (UGR) have become key parameters.
The key trend in modern lighting technology is the Human Centric Lighting (HCL) concept. The discovery of photosensitive retinal ganglion cells proved that the spectral composition and intensity of light directly govern our circadian rhythms. By changing the colour temperature (from a warm, relaxing 2700 K spectrum to a cold, invigorating 6500 K) during the day, modern dynamic lighting systems synchronise the production of melatonin and cortisol, improving concentration during the day and promoting deep sleep at night.
The integration of lighting technology with digital protocols (DALI-2, Zigbee, Bluetooth Mesh) and presence and daylight sensors has turned luminaires into key nodes of smart buildings and cities, where light switches on exactly where and when it is needed.
