Workers of 24/7 environments that are deprived from sunlight are particularly vulnerable to shift work disorders with a negative impact on workers’ health and productivity. Our light modules can be programmed to follow natural daylight patters to promote the synchronization of the circadian rhythms, enhance alertness and productivity, generally improving the working conditions and quality.

Case study: Repsol 24 hours control room

The goal of this lighting installation was to bring natural light into a 24-h control room of the Repsol oil refinery plant located in Tarragona, Spain. The circadian lighting solution installed used downlights with LEDMOTIVE VEGA 10 spectral control technology inside to follow the circadian rhythms of the workers along a cycle of 24 hours.

Ledmotive case study Repsol

The goal of this lighting installation was to bring natural light into a 24-h control room of the Repsol oil refinery plant located in Tarragona, Spain. The circadian lighting solution installed used downlights with LEDMOTIVE VEGA 10 spectral control technology inside to follow the circadian rhythms of the workers along a cycle of 24 hours.

This advanced lighting system reproduce the dynamism of the natural light into the work environment, to increase the feeling of well-being and provide a suitable atmosphere by increasing the performance, concentration and motivation of employees.

In order to carry out the light analysis and to design the most optimal illumination for this type of working environment, a balance has been taken between the working area to be illuminated, the intensity of light and the distribution of the luminaires inside the control room.

Lighting configuration:

  • Screen displays withilluminance levels Em = 500 lux
  • High visual quality with color rendering index: CRI > 95.
  • Lighting sequences for every work shift: morning, afternoon and night changing from 3000 K to 5500 K
  • Sequence1: light spectrum changingfrom 3.000 K to 5.500 K with the main goal to inhibit the secretion of melatonin, speed up of the concentration and keep  alertness state at the beginning of the shift.
  • Sequence2: ramp down from 5.500K to 4.500K with the main goal to stay focus and alertnesswith a warmer light for the rest of the shift.
  • Sequence3: light spectrum stabilized with CCT 4.500K close to the sun light.
  • Sequence4: ramp down from 4.500 K to 3.000 K toprepare the worker to leave their work station. Progressive inhibition of the Blue light keeping the appropriate light on the workspace.

Final results:

  • Improvement in worker productivity due to the high quality of the circadian lighting solution.
  • 65% reduction in display screen reflections in the control room
  • Tunable lighting solution that avoids forcing the eyesight or generating glare discomfort

Case study: ILBOC 24 hours control room

Iberian Lube Base Oils Company, S.A. (ILBOC) is a company that produce lubricant bases (LBO) (group II and III) at its plant located in the Escombreras Valley (Cartagena). The lighting system designed for the ILBOC facilities was intended to bring natural light to the control room for each work shift according to the circadian rhythms.

Ledmotive case study ILBOC

This project aims to transfer the dynamism and characteristics of natural light to the work environment, providing an adequate atmosphere and with the potential to increase the feeling of well-being, motivation, concentration and performance of employees. Dynamic lighting sequences were defined in compliance with Spanish Royal Decree R.D 486/1997 and following the EN 12464-1 standard for workplaces with high visual requirements.

Lighting sequences  uses ascending and descending ramps to modulate worker melatonin levels, accelerate concentration and alertness in the workplace. In addition, a final sequence was developed to inhibit blue light but not excessively for operators at the end of the workday.

The lighting solution selected was LEDMOTIVE VEGA 07 module with spectral control inside working as an autonomous control system with an embedded computer to provide the correct sequence and time slots to update the spectrum according to the biological rhythms of the operators in each work shift.
