Definitions

  • This industrial invention refers to an electronic device to be retrofitted in the traditional electric circuit of cars, motorcycles or other vehicles and which is capable of automatically switching on the headlamps when the engine is started, thereby ensuring compliance with current road regulations requiring vehicle users to drive with their lights on even in the daytime.
  • the headlamps switch off automatically, but not on, as the current of the battery would not be completely available for starting the engine.
  • the principal aim of this invention is to eliminate said limitations by means of a device, retrofittable in either type of circuit, which automatically switches on the headlamps when the engine is started, allowing a fixed amount of time to elapse first so as not to divert the current necessary for ignition, and then turns them off without there being any need to operate a switch. Thus the user is freed of every task.
  • -a- indicates the car battery
  • -b- the headlamp bulb
  • R a series of resistors specified in the table
  • C a series of capacitors
  • D a series of diodes
  • IC1 an integrated circuit
  • RL a relay and TR1 a transistor.
  • the recommended values of the components are as follows:
  • the circuit When the circuit is retrofitted in a traditional electrical system, in this specific case the key operated type with the "light switch on”, it works in the following manner: when the ignition key is turned , the integrated circuit (IC1) is energized at pins 4 (Reset) and 8 (Vdc) at a voltage between 5 and 15 Volts, levelled by the electrolytic capacitor (C3).
  • the capacitor (C1) and resistor (R1) give the time constant that determines the desired delay in the illumination of the headlamps.
  • a diode (Ds1) When the circuit is de-energized, a diode (Ds1) immediately discharges a capacitor (C1) to prepare the circuit to repeat the cycle.
  • the pin indicated by the number 5 (Voltage control) is not used and is earthed via a capacitor (C2).
  • a second diode (Ds2) serves to protect the integrated circuit (IC1).
  • a third diode (Ds3) serves to damp the voltage peaks generated in the coil of the relay (RL) which acts like an inductor when power is cut off.
  • a capacitor (C4) serves to limit the sparking of the relay contacts (RL).
  • Fig. 2 shows a power transistor (TR1) - installed in place of the relay (RL) and performing the same functions ⁇ with the polarization network formed by (R2) and (R3).
