As a part of a large-scale reconstruction program at VDNKh, an LED lighting system from the IntiLED Company was installed on the facade of the Pavilion 71 Atomic Energy.
600 white luminaires were used for the implementation of the lighting project. The main task of the designers was the choice of color temperature. It was necessary to highlight the various textures and colors of the Pavilion cladding, taking into account the requirements for architectural lighting of facades in the territory of VDNKh. Neutral white light (4000 K) was chosen as the main one, and the color temperature for lighting spaces behind the columns, frescoes, sculptures, and the crowning cornice was selected by mixing warm white and amber colors. A non-standard variant of controlled RGB-luminaires with white and amber LEDs was manufactured for the implementation of the design project. Specialists needed the control feature to fine-tune the color on the spot. Installed luminaires do not distract from the magnificent architecture of the Pavilion. For this special purpose, such locations were selected to prevent their from getting in the field of view of passers-by and visitors to the Pavilion.
The brightness of accent elements grows gradually from the bottom upwards. Each of the columns of the portico is illuminated by four spotlights of the IntiGROUND series with the beam angle of 10°. The entablature is emphasized by the IntiSLIM series luminaires, which are invisible on the facade due to their compact size. Luminaires of the IntiSTARK and IntiLINE series of various lengths are used for the uniform floodlighting of the front facade. The sculptural composition of cornucopias with the emblem of the USSR, which is a crown of the portico, is illuminated by a luminaire of the IntiLINE series.
The total power consumption of the entire lighting system of the Pavilion is as little as 30 kW. The equipment operates in three modes: evening mode, night mode, and festive mode. The evening mode is the most frequently used one. It is a combination of shades of white light on various architectural elements of the Pavilion. The festive mode allows using the entire RGBW palette of lighting colors, changes the brightness and color of the facade in real time. The night mode implies calm lighting.
The design, supply of equipment, architectural supervision, and commissioning, including adjustment of the lighting control system, was performed by the HELIOСITY lighting company
