Definitions

  • the present invention relates to an apparatus for adjusting alternating-current lighting devices, for example incandescent, fluorescent, mercury vapor, metal iodide lamps or the like.
  • the present invention also relates to a process which can be carried out through said apparatus.
  • Known apparatuses for adjusting alternating-current lighting devices comprise an input connector and an output connector electrically connected through a voltage regulator.
  • This voltage regulator generally comprises an inverter or a dimmer, which involve relatively high complexity and costs.
  • the apparatus according to the present invention allows to reduce the manufacturing and maintenance costs, as well as the electric energy consumed by the lighting devices, especially if the apparatus carries out the process according to the present invention.
  • the voltage of the lighting devices can be adjusted in an optimal manner with a reduced number of automatic switches.
  • the voltage of the lighting device can also be adjusted without annoying sudden variations and with an accurate control of turning-on, working and/or turning-off of the lighting devices.
  • the apparatus comprises in a known way an external casing EC provided with an input connector IC for the electric connection to an alternating-current source comprising a phase line L and a neutral line N, in particular at a voltage of 230 or 400 V.
  • External casing EC is also provided with an output connector OC for the electric connection to one or more alternating-current lighting devices LD, always through a phase line L and a neutral line N.
  • Input connector IC and output connector OC are electrically connected to each other through at least one phase line L and one neutral line N.
  • a manual switch MS can connect directly, in a first position thereof, input connector IC to output connector OC. In a second position of manual switch MS, input connector IC and output connector OC are electrically connected through a voltage regulator VR.
  • Voltage regulator VR comprises a transformer T, in particular an autotransformer, which is electrically connected to input connector IC through phase line L and neutral line N.
  • a plurality of controlled switches CS are connected in parallel between the taps of a winding of transformer T and output connector OC, so that output voltage Vo between phase line L and neutral line N of output connector OC can be varied with respect to input voltage Vi between phase line L and neutral line N of input connector IC.
  • Said voltage variation is obtained by closing at least one controlled switch CS, so as to obtain an output voltage Vo equal to the difference of the voltages at the taps of transformer T connected to the closed controlled switches CS.
  • first tap T1 and last tap Tn of the winding of transformer T are connected to neutral line N and phase line L, respectively, so that voltages V1 and Vn at these taps correspond to the voltage of neutral line N, namely 0 V, and to the voltage of phase line L, in particular 230 or 400 V.
  • the voltage difference between tap T1 connected to neutral line N or tap Tn connected to phase line L and the intermediate tap T2 or Tn-1 adjacent to the latter tap is relatively low, for example 5 V, so as to obtain a fine adjustment of the voltage.
  • controlled switches CS comprise TRIACs provided with opto-isolators OI, however in other embodiments controlled switches CS can comprise pairs of thyristors or SCRs connected in antiparallel, static relays or other equivalent devices.
  • Control gates of controlled switches CS are connected through at least one control line CL to an electronic control unit CU which is provided with a microprocessor MP for executing operating sequences, with a programmable timer PT for determining the on and off times of lighting devices LD and with one or more interfaces for the connection to electric or electronic devices, in particular to at least one light sensor LS provided with a photodiode suitable for measuring the light intensity in the environment comprising lighting devices LD.
  • Control unit CU is powered by a power supply PS connected to input connector IC.
  • Control unit CU is also connected to input/output means IO, in particular comprising a keyboard and a display, for controlling the working of the apparatus, to a temperature sensor TS arranged close to transformer T for measuring the temperature of the latter, to manual switch MS for controlling the position of the latter, to neutral lines N and phase lines L of input connector IC and of output connector OC for measuring input voltage Vi and output voltage Vo, respectively, to a safety relay SR for disconnecting, if necessary, transformer T from input connector IC, to an ammeter AM arranged on phase line L for measuring phase current I, and/or to a network interface NI for connecting control unit CU to a computer network.
  • input/output means IO in particular comprising a keyboard and a display
  • a temperature sensor TS arranged close to transformer T for measuring the temperature of the latter
  • manual switch MS for controlling the position of the latter
  • neutral lines N and phase lines L of input connector IC and of output connector OC for measuring input voltage Vi and output voltage Vo, respectively
  • a safety relay SR
  • Control unit CU is further connected to two taps of a secondary winding of transformer T for controlling the phase of current I. Such taps are connected to a cooling fan CF and the voltage between them is low, in particular 18 V. Fuses F are arranged at different points of the apparatus, in particular on phase line L, on neutral line N and on the lines connecting transformer T to controlled switches CS.
  • Control unit CU can be connected to optional devices OD and/or to a radio receiver RR, in particular for receiving the signals of one or more light sensors LS suitable for measuring the light intensity in the same environment of light devices LD.
  • control unit CU is programmed for adjusting lighting devices LD through voltage regulator VR by means of the following adjustment process.
  • control unit CU checks in programmable timer PT whether at that moment lighting devices LD must be on, namely if a light timer LT is in an ON position.
  • control unit CU checks whether lighting devices LD are already on, namely Vo>0.
  • control unit CU ends the adjustment process (End), while in the negative (N) control unit CU checks whether light intensity LI is greater than maximum value Lmax (otherwise lower than minimum value Lmin).
