Intense Lighting Without Glare

ALFMEIER CZ s. r. o.

The project for ALFMEIER CZ demonstrates that the requirement for high-intensity lighting without glare or uncomfortable transitions between light and dark can be met to the full satisfaction of the users.

A high-angle overview of a busy production hall. Workers in blue t-shirts are seated at assembly tables separated by glass partitions. A dense network of cable trays and pipes runs above the production lines. The hall is well-lit by multiple light fixtures mounted on the overhead beams. Blue crates and boxes of material are scattered throughout the space.

The company's production facility is very densely packed with technology and contains numerous workstations. The goal was to provide high-quality illumination for the entire area using ceiling lighting. In addition to significant energy savings, other key requirements included:

  • Lighting Uniformity: Every workstation had to be perfectly illuminated. The grid layout of the luminaires was designed to prevent the workspace from being shaded by technology or the workers themselves.
  • Lighting Levels: Due to the nature of the work—the assembly of small components—it was necessary to ensure a lighting level of at least 500 lux.
  • Comprehensive Lighting Control: The client required an automated control system based on daylight harvesting with individual luminaire addressing. The system needed to allow for easy reconfiguration of lighting groups according to the production plan and workstation layout. This was to be complemented by energy consumption metering and system performance reporting.

In the warehouse, we implemented lighting control based on employee movement within the racking aisles, accounting for entry from multiple directions. It was also crucial to ensure that employees do not move from bright areas into darkness, which was successfully achieved by the system's rapid and reliable response.

We utilized doublepower T5 and doublepower ONE luminaires. Part of the existing electrical installation was reused, while the remainder, including current switchboards, was retrofitted. We installed a bus control system based on the DALI-KNX standard. Authorized personnel at the customer site now have access to a clear visualization and management interface for the entire lighting system.

A sign with a vacuum cleaner icon and the number 7 hangs overhead. The hall appears clean, organized, and modern, illuminated by long rows of ceiling lights.
