Definitions

  • the present invention relates generally to an equipment for transforming a lighting apparatus in an emergency lighting apparatus.
  • the invention concerns a hardware system for the simple transformation of a lighting apparatus in an emergency lighting apparatus; it is actually a module which can be mechanically and electrically integrated into traditional lighting apparatuses, de facto transforming them into permanent or emergency lighting systems.
  • the system is particularly suitable for the use in pre-assembled ceiling light fixtures, of the watertight type, for watertight and anticorrosion environments and with fluorescent tubes, but it can be generally adopted even in lighting apparatuses of different kinds.
  • inverters which are inserted into the original body of the lamp (ceiling light fixtures) and which generally include a casing, containing the electronic parts, a batteries pack, usually connected with the casing, through proper electrical wiring, and at least a LED or other device suitable to view the operation status of the system.
  • figure 1 attached shows the rear view of the reflector of a lighting apparatus with two fluorescent lighting sources of 58
  • figure 2 attached shows the rear view of the reflector of the same apparatus in the emergency lighting version, where the new electrical wirings, as well as the inverter IN and the batteries pack B are visible.
  • the major emergency lighting apparatuses manufacturers prefer to directly provide the embodiments equipped with the kit and the wiring of the emergency version, in order to make properly done electrical connections and in order to certify the overall performances resulting from the apparatus.
  • the temperatures inside the ceiling light fixture are generally very high (typically they exceed 60°C), due to the heat generated by the lamps and the relative power suppliers, and thus hardly compatible with the use of batteries packs (even if of specific type); it follows that, at the best, the useful life of the batteries and the electronic circuits of the inverter will be reduced (life is halved every 10°C of temperature increase; for instance, 4 years at 45°C become 2 years at 55°C, which lower to 1 year at 65°C).
  • the useful life of the light source is compromised during the emergency operation, due to the non-compliance with the operating parameters of the aforesaid source, since, during the emergency operation, energy is supplied by a battery having a limited capacity (for size constraints) and, therefore, not allowing to provide the nominal power of the lamp (for example, in a watertight ceiling light fixture of 58 Watt, in ordinary operation each lamp is usually fed at 58 Watt, while in emergency operation the inverter provides 5-6 Watt, thus about 10% of the nominal power); the circuits used in the inverter, for reasons related to the transformation efficiency and costs, do not provide pre-heating systems of the cathodes and, therefore, with powers so limited, the average life of the lamp can be reduced even to 100 hours of operation, against the nominal 12.000-15.000 hours.
  • Purpose of the present invention is, therefore, to overcome the drawbacks complained, creating an equipment for transforming a lighting apparatus in an emergency lighting apparatus, which allows the manufacturer to significantly reduce the number of lighting products to be managed, thus limiting the costs of construction and operation.
  • Another purpose of the present invention is to provide an equipment for transforming a lighting apparatus in an emergency lighting apparatus, which allows to avoid turning on problems at low temperatures, while keeping an excellent useful life of the batteries packs and lighting sources, even during the emergency operation.
  • Another purpose of the present invention is to create an equipment for transforming a lighting apparatus in an emergency lighting apparatus, which has an excellent quality/price ratio and presents an extreme ease and speed of construction and installation of the equipment and maintenance of the lamps and/or the electronic control circuits.
  • Further purpose of the present invention is to create an equipment for transforming a lighting apparatus in an emergency lighting apparatus, which allows to carry out simple wirings and various arrangements of the lighting apparatuses, during their installation.
  • the invention allows to significantly reduce the temperature which develops on the sensitive components, such as batteries and inverters, thanks to the position defined externally the heat source, with additional undoubted advantages in terms of useful life, particularly for the batteries, which will assure the minimum life of four years, as required by the law in force.
  • the photometric performances obtained with a dedicated source are optimized for the specific operation of the emergency lighting; indeed, the light is directed where most useful, regardless of the optical configuration of the original lamp, maximizing the efficiency thereof.
  • the auxiliary LED assures a virtually infinite emergency operation and, secondly, the primary light source is not damaged by a possible emergency operation and will assure the nominal useful life.
  • the equipment for transforming a lighting apparatus in an emergency lighting apparatus which is the object of the present invention, consists of an autonomous module, which can be advantageously combined with watertight fluorescent tubes ceiling light fixtures, which exploit in particular the constructive characteristics thereof.
  • the ceiling light fixtures in question are composed, specifically, of a metallic and glass central body 10, which protects the fluorescent light sources and the reflector, and two removable lateral heads 11, closing the central body 10, which incorporate respective seal elements, suitable to assure an appropriate degree of protection, and exploitable for the electrical wiring.
  • the equipment or module 12 suitable to transform a lighting apparatus in an emergency lighting apparatus, which is the object of the invention, actually replaces one of the original heads 11, assuring the operation of emergency equipment, thanks to the use of an inverter, with related batteries pack, and a LED light source, which are contained inside the module or head 12.
  • the new closing head 12 thus obtained guarantees the original degree of protection, assuring at the same time a proper functionality in emergency condition, as the system of sealing and closing of the new head 12 reproduces that one of the original head 11, thereby assuring also a perfect interchangeability of the heads 11, 12.
  • the new closing head 12 which actually is the autonomous module suitable to transform the lighting apparatus in an emergency lighting apparatus, basically consists of an outer casing 3, connected with the central body 10 of the lighting apparatus and made preferably of aluminum die-casting, within which an internal protective cover 6 is inserted, which contains an electronic circuit (inverter) 5 to which a batteries pack 4 is associated.
  • an auxiliary optical unit 2 containing a signaling LED, on which a lens 1 is positioned, is fixed to the outer casing 3.
