Lighting accounts for more than 19% of the world’s electricity consumption. Simply replacing existing lighting systems with other LED technology would reduce energy consumption by up to 40%, and if we also use lighting controls, the figure can reach 80%. The transition to efficient lighting technologies (LEDs) is economically one of the most realistic and simple energy efficiency initiatives. Control systems play an important role in the world of lighting. Wherever you have exterior lighting, there will be a need for control. The systems that have been used so far have precedents that date back more than 35 years and allow control and monitoring functions of groups of light points, i.e. not individually. One of the major drawbacks of these systems is that they do not have flexibility, since they do not allow the individualization of the point of light, and in addition the orders that can emit are of generic character and affect the group, obtaining a rather inaccurate information of the installation. Complete telemanagement systems are currently being developed to meet the needs of different application segments. Experience shows that it is necessary to work with open systems so that the lighting management system works and communicates with other systems such as air treatment, safety systems, etc. Intelligent lighting, in addition to its control and energy management functions, also contributes to reducing the excess of artificial light to which our cities are subject, making them more livable.

Today LED technology is being imposed, day by day, in our cities and homes as an efficient way of lighting. The performance of its lighting, durability, energy efficiency, and light, coupled with the economy of its use, is shifting to other classic forms of lighting. However, some problems associated with the durability of equipment associated with thermal dissipation and high-temperature problems, which end up affecting the light intensity and service life, are beginning to be detected. The objective of this paper is to compare the results obtained previously, at different contour temperatures, with the current practical results obtained with a FLUKETI25 thermal imaging camera. The theoretical results will be compared with the current results applied to the different luminaires. Where real thermal dissipation is studied, it is obtained for each of them in the laboratory of illumination with the thermographic camera FLUKE TI. The theoretical and experimental results are evaluated, and the results are discussed. This study shows that instead of LED technology, it is less risky for quality depreciation and durability of lighting if a project has already been achieved that favors optimal thermal dissipation, supported by the importance of choosing an appropriate design and appropriate materials.
