dc.description.abstract In the competition of the lighting market, LED technology has stood out for excellent characteristics, one of which is the possibility of dimming, compared to other technologies. The dimming capacity allows to find the comfort zone with respect to two parameters, illuminance and correlated colour temperature (CCT). The present work provides a methodology to find comfort with respect to two variables, the level of illumination and the CCT. A controller with a simple structure, supported by Arduino, is proposed to control the above-mentioned variables of LEDs. The LEDs are located on a tape attached to a heat sink. In addition, the use of a light box as an environment for analysis is proposed. The design of this cubicle is based on literature. The controller has the possibility to regulate 12 different channels and the linearity between the PWM output and the illuminance was verified. The cubicle has an area for the observer whose dimensions are 60 cm × 60 cm. In this area, the illuminance measurement was carried out over time and the almost null variation of the illuminance 347± 1 lx was confirmed while the CCT varied in a controlled way from 3000 K to 6500 K. © 2021 Published under licence by IOP Publishing Ltd.
