Definitions

  • the instant invention relates to an electronic device for saving electrical power, to be used in lamps of any kind or for resistive or capacitive loads, by decreasing the electrical current feeding the loads, at pre-determined time periods, by means of timing, sinusoidal wave rectifying and reducing the power.
  • thermostats which decrease light intensity, through partial dissipation of the current in a resistor.
  • dimmers were developed which decrease light intensity of the lamp by decreasing the power supply voltage. Their use is however limited to incandescent lamps, and they are relatively expensive and have no timing features.
  • a first aspect of the invention provides a timed power saver, comprising an electronic timer, connected in parallel with a half-wave rectifying diode and both connected to a phase conductor, the timer and diode being connected in series with a resistive or an inductive load and also in parallel with a second conductor, which is either neutral or of another phase.
  • the timed power saver of the invention was developed in order to overcome the disadvantages of present systems, since the device may be used in any kind of lamp (Mercury vapour, incandescent, fluorescent, sodium vapour, multi-vapour, halogen, etc.), on resistive loads and capacitive loads since timing may be programmed, therefore the time of power decrease may be predetermined; it extends the life of reactances and lamps, may be connected to a lamp or to a group of lamps, has low cost, saves electrical power and is of small size.
  • lamp Mercury vapour, incandescent, fluorescent, sodium vapour, multi-vapour, halogen, etc.
  • the power saver includes at least one further resistor connected in parallel to the timer and the diode.
  • the resistor may be a variable resistor or a plurality of fixed value resistors connected in parallel and individually selectable by one or more switches.
  • Figure 1 is an electrical diagram of a first embodiment of the timing and power saving device for discharge lamps (Mercury vapour, sodium vapour, metallic vapour, etc.) comprising an electronic timer 1, connected in parallel to a half-wave rectifying diode 2 and four fixed value resistors 3 arranged parallel therebetween and selectable by switches 4, all connected to a phase conductor 5, and in series with a resistive load 6, normally a lamp or a group of lamps which is arranged in parallel to a conductor 7, which is of neutral or of another phase.
  • a resistive load 6 normally a lamp or a group of lamps which is arranged in parallel to a conductor 7, which is of neutral or of another phase.
  • Figure 2 is an electrical diagram of a second embodiment of the timing and power saving device at inductive loads, comprising an electronic timer 1, connected in parallel to a half-wave rectifying diode 2 and to a variable resistor 8, all being connected to the phase conductor 5 and in series with an inductive load 9 and with the conductor 7 which is of neutral or of another phase.
  • Operation of the power saving device of the invention is based on the elimination of the half-wave by diode 2 and, through the action of two resistors 3 or a variable resistor 8, the electrical power supply being decreased during the discontinuity of the sinusoidal wave and, consequently, the power of the resistive or inductive load is also decreased.
  • the electrical current will be reduced to variable values, depending on resistors 3 or 8, between 1 and 99% of the normal current.
  • Diodes 2 used may be negative or positive diodes, which should be equally mixed thus avoiding the electrical power supply unbalance.
  • the dimensioning is extrapolated for loads of different powers, such as sodium vapour discharge lamps, metal vapour discharge lamps, etc.
  • the energy loss due to the use of two resistors 3 or 8 is estimated between 5 and 17W in the examples.
