The purpose of this study is to simultaneously analyze the different risk factors (lighting, noise, and ergonomics), obtain an overall assessment of the risk of these factors and classify them in scales of levels of: Very poor, poor, good and very good, from three libraries of the National University of Engineering. In order to classify them, the grey clustering method was used, which establishes two types of data: Standard data and sampling data, the first one refers to the minimum standards required to be met by a library according to each criterion (lighting, noise, ergonomics). The second one refers to the real data obtained in the field. Both data are evaluated in the indicated methodology and the clustering vector is constructed, which will allow to classify the libraries in the scales of established levels. According to the results obtained, it was determined that the lowest noise levels were obtained in the library of the Faculty of Environmental Engineering; nevertheless, these levels are not within the minimum standards of noise for libraries; in addition, it was determined that the lowest values obtained in illumination of each library correspond to the library of the Faculty of Environmental Engineering, since it is in levels of illumination significantly below what is required according to the minimum standards. On the other hand, adequate lighting levels were obtained in the library of the Faculty of Sciences, and it was determined that the best ergonomic comfort was obtained in the Central Library. According to the overall assessment of each of the libraries under study, according to the scale of levels established, it is concluded that the library of the Faculty of Environmental Engineering is at a poor level with respect to the other libraries (good level).

“…In [2], an evaluation of LED luminaires was conducted to determine if there are direct substitute for traditional incandescent light bulbs based on the basic evaluation criterion of illuminance, uniformity and glare limitation in the place of work. Their study indicated that not all light sources can be considered substitutes of traditional light bulbs.…”

Illumination of the scene is crucial in order the detection algorithm to carry out the computation task correctly. In this study, an LED based luminaire is developed for a computer vision system for the detection and tracking of pedestrian or human body in a video under different illumination. The illumination is provided using an LED lighting system where the intensity of illumination can be varied by changing the duty cycle of the pulse activating the LEDs. The mean of ambient light intensities captured by the image sensor is captured under different lighting conditions which will be useful in designing a control system that consider the amount of ambient lighting to set the setting of LED lighting activation. This adaptive system is useful to provide illumination that take into consideration ambient light intensities.
