All lights are equipped with energy saving function which will automatically become the level of attenuation after the visitors exit. PIR (Passive Infrared) sensors are used in the system instead of a video camera in order to reduce costs and privacy. The luminaires are also designed to have a network interface so they can be connected to each other to form an intelligent lighting system that can not only collect exposure information but also help managers to ensure exposure.
Lighting system is one of the most important elements in the exhibition space, eg. museum or art gallery. How to protect photo-sensitivity exposures to make the highest quality exposure is a key issue in light environment design research. You can make use of more efficient artificial lighting and greater degree of comfort. Works of art usually need to be seen in the center by the light track system that the typical lighting is 3000 K to 200 lux. In addition, there are other lighting systems that are used to increase lightness or as a moving guide sign in the same space. All lighting systems are complicated and influence the vision to see. Therefore, the exhibition space managers face the constant demand to gain greater control of the interior environment, under increasing budgetary constraints. In addition, the preservation of works of art in the exhibition space is also a well-known problem, either in exhibition halls or in archival collections. Monitoring the environment is one of the most important tasks and concerns of the entire exhibition space. Nowadays, video camera application systems can be seen in the exhibition, but most of them are expensive and without personal privacy. A passive infrared sensor (PIR sensor) are used in the system instead of a video camera for both low cost and privacy purposes. A PIR sensor is a device that measures infrared (IR) light that radiates from objects in its field of view. PIR sensors are often used in the construction of human motion detectors. It is usually infrared radiation that is invisible to the human eye, but can be detected by electronic devices designed for this purpose. In order to properly preserve the work of art it is essential to continuously measure and control some parameters, such as radiation and lighting. It is also crucial to consider that the desirability values of these parameters depend on the type of materials constituting the work of art. That is to say, depending on the type of works that are in exhibition or warehouses, different rooms may have different requirements regarding the environmental conditions. Therefore, it will be necessary to design the lights to have network interface so that they can be connected together to form an intelligent lighting system.
