Definitions

  • This invention is related to the field of street lighting devices, and more particularly, to the functionalities of these devices.
  • [2]Electric or hybrid vehicles which are adapted to be connected to the main supply to recharge their batteries, may be charged in many different locations.
  • [5]Other option is that the charger is not connected, but it requires the user to reach the charger or the vehicle and check in situ the charge level.
  • a control unit being configured to receive information about the vehicle and about a user of the vehicle and configured to receive information from the vehicle charger about the charge status of the vehicle;
  • a lighting device being connected to the control unit and comprising a presence detector for detecting the presence of the user of the vehicle and a lighting projector integrating a solid-state light assembly configured to project a light pattern with information about the charge status of the vehicle.
  • solid state refers to light emitted by solid-state electroluminescence, which uses semiconductors to convert electricity into light. Compared to incandescent lighting, solid state lighting creates visible light with reduced heat generation and less energy dissipation.
  • the typically small mass of a solid-state electronic lighting device provides for greater resistance to shock and vibration compared to brittle glass tubes/bulbs and long, thin filament wires. They also eliminate filament evaporation, potentially increasing the lifespan of the illumination device.
  • Some examples of these types of lighting comprise semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer light-emitting diodes (PLED) as sources of illumination rather than electrical filaments, plasma or gas.
  • This system allows the user to know the charge level of the vehicle without reaching the vehicle or the charger.
  • the lighting projector projects information about the charge level of the vehicle without the need of the user to grab the mobile phone or look at any other screen. This is especially useful when the user has his hands full and therefore cannot reach it.
  • the system is configured to project the information just by detecting the presence of the user.
  • the presence detector comprises a camera or a wireless connection device, such as an infrared connection device or a radiofrequency connection device, for example ISM band or ultrawide band UWB connection device.
  • a wireless connection device such as an infrared connection device or a radiofrequency connection device, for example ISM band or ultrawide band UWB connection device.
  • the presence detector needs to detect the presence of the particular user. This can be made by many different strategies. One is by means of a camera. A camera acquires images that are sent to the control unit. The control unit may comprise a recognition program that identifies key features of the user and recognizes the user when approaches again the charger. Another option is a wireless connection device, such as a radiofrequency connection device. There are many types of radiofrequency connection devices, but they are suitable to detect the presence of a cooperating device worn by the user. When the presence of the cooperating device is detected by the presence detector, the instructions are sent for projecting the charge level.
  • control unit is configured to receive the information about the vehicle, about the user and about the charge status by means of a server.
  • control unit comprises an input device and is configured to receive the information about the vehicle, about the user and/or about the charge status by means of the input device.

  • the lighting device is a street lighting equipment which comprises a mast and a lighting projector.

  • the substrate may be predominantly made of a semiconductor material.
  • the substrate may comprise one or more other materials, for example non-semiconductors (metals and insulators).
  • each electroluminescent element/group can form a light pixel and can therefore emit light when its/their material is supplied with electricity.
  • the configuration of such a monolithic matrix allows the arrangement of selectively activatable pixels very close to each other, compared to conventional light-emitting diodes intended to be soldered to printed circuit boards.
  • the monolithic matrix may comprise electroluminescent elements whose main dimension of height, measured perpendicularly to the common substrate, is substantially equal to one micrometre.
  • the monolithic matrix is coupled to the control centre so as to control the generation and/or the projection of a pixelated light beam by the matrix arrangement.
  • the control centre is thus able to individually control the light emission of each pixel of the matrix arrangement.
  • the matrix arrangement may comprise a main light source coupled to a matrix of mirrors.
  • the pixelated light source is formed by the assembly of at least one main light source formed of at least one light emitting diode emitting light and an array of optoelectronic elements, for example a matrix of micro-mirrors, also known by the acronym DMD, for "Digital Micro-mirror Device", which directs the light rays from the main light source by reflection to a projection optical element.

  • an auxiliary optical element can collect the rays of at least one light source to focus and direct them to the surface of the micro-mirror array.
  • each micro-mirror can pivot between two fixed positions, a first position in which the light rays are reflected towards the projection optical element, and a second position in which the light rays are reflected in a different direction from the projection optical element.
  • the two fixed positions are oriented in the same manner for all the micro-mirrors and form, with respect to a reference plane supporting the matrix of micro-mirrors, a characteristic angle of the matrix of micro-mirrors defined in its specifications. Such an angle is generally less than 20° and may be usually about 12°.
  • each micro-mirror reflecting a part of the light beams which are incident on the matrix of micro-mirrors forms an elementary emitter of the pixelated light source.
