Definitions

  • the present invention relates to the technical field of lighting, and in particular to the intelligent management of indoor lighting. More particularly, the invention relates to an apparatus and a method to manage indoor lighting, and also air-conditioning, video surveillance, alarms in a personalized way through the interaction with a portable device.
  • Lighting systems are known using motion and/or occupancy sensors starting in the presence of a person inside a pre-set area, and switching off after a given pre-set time, in case of absence of persons in the pre-set area.
  • Entity Elettronica's ITPD20090154 discloses an indoor lighting system, wherein motion or occupancy sensors switch on the lighting, and the single lighting devices can adjust lighting conditions according to the presence or absence of at least a person, or according to the fact that the person is approaching or leaving. Moreover, the same document discloses that the lighting elements can exchange information to progressively switch on the lighting and the successive switching off of the elements themselves, so as not to dazzle the human subjects who are present in sectors neighbouring to the sector the person is moving.
  • Philips' s Patent EP2084945B 1 too discloses a system of lighting tiles that switch on and off in the presence of at least a person; moreover, they are provided with a communication device which can interact with a corresponding device (e.g. RFID or NFC) carried by the person her/himself. Said device interacts with a sensor network. The sensors can detect the wireless signal intensity deriving from the portable device, allowing to detect the person's distance and direction of motion, starting the tiles lying in the person's direction of motion.
  • a corresponding device e.g. RFID or NFC
  • Carmanah Technologies' s EP2168407B1 is quite similar to EP2084945B1; in this case, too, occupancy/motion sensors are involved, but here the persons carry no device.
  • the lighting elements are provided with a communication system constituting a network, and are pre-programmed so as to determine the activation of a group of lighting elements once the person has entered the area making part of the group.
  • the parameters for activating the following devices on the path are determined as a function of the speed of motion.
  • a feature in common among the three above-mentioned documents is that in all of them occupancy/motion sensors must be used. If this is unavoidable outdoors, wherein the persons interacting with the lighting systems can be any people, therefore possibly not provided with identifying systems, indoors (residential buildings, working environment) the access of persons is supposed to be controlled, and a list of persons authorised to access is supposed to exist, and therefore all the persons can be provided with a portable device.
  • the lighting devices of known type connected to a network are generally also connected to a centralized control and management device, at least to manage fault detection.
  • the centralized device adds costs to the system and decreases its reliability.
  • a centralized system is not economically advantageous when the lighting system comprises a small number of elements and/or the covered area is very small.
  • a further patent application discloses a lighting system wherein the lighting elements form a network according to a known wireless communication standard; both a wall switch and a specific program resident on a PC or on a portable device known as smartphone can control the lighting elements.
  • occupancy/motion sensors are missing, but the communication devices embedded in the lighting elements automatically interact with each other and with the portable device, with no centralized control.
  • the absence of a centralized control system entails the need to have an important portion of electronic circuits positioned on each lighting element, with an increase in cost and complexity of the system.
  • the user in order to use the system, the user must perform a voluntary action, like using a switch or a graphical interface on a portable device.
  • Said sensor actively detect the presence of persons, and are in combination with processing units which, according to the data detected by the sensors themselves, generate command or control signals thanks to control logics embedded in the processing units placed in the single lighting elements.
  • a first drawback of the known art is that providing each single lighting element with sensors of the state-of-the-art known type entails the sensor cost multiplied by the number of the lighting elements inside the system. Moreover, remarkable problems can occur in the calibration of said sensors, both when installing them, and in time, due to their drift.
  • a second drawback is connected to the problem of system reliability, in that reliability worsens exponentially and not linearly with the increase in the number of components of the system and their complexity.
  • a third drawback is due to system complexity: when a network of sensors has to be configured, having each a dedicated control unit consisting of a hardware performing a control logic program, which not only manages the commands of the controlled lighting element, but also the network formed by the single control units associated to other lighting elements of the system and of a possible centralized server, the configuration must take into account their of their distribution in space. This can be very complex when the configuration must be performed on the single lighting element, more so in case of successive modifications and even more so when the lighting elements are placed in difficult to access positions.
  • Aim of the present invention is providing a lighting system free of the above- mentioned drawbacks, preferably for indoor environment, wherein the adjusting of the lighting elements is obtained without motion and/or occupancy sensors, replacing them with a wireless communication system.
