  • lighting devices e.g. LED lamps
  • the variation of the emission wavelength (colour shift) depending on current and/or temperature may be controlled and intentionally induced, e.g. in order to produce warning and/or alarm signals in sectors such as the automotive sector.

  • light source L is adapted to be powered by a power source (which in the present case is exemplified as a voltage generator V1) which may be associated to a driver 12 adapted to operate e.g. as a function of a drive signal A, as better detailed in the following.
  • a power source which in the present case is exemplified as a voltage generator V1

  • Reference 14 schematically denotes clamps or terminals which may be employed for mounting source L, being adapted to establish both the electrical connection with the supply circuit V1, 12, R2 and the mechanical fixation of source L in a mounting housing thereof.
  • a housing may comprise e.g. a reflector R of a headlamp, which may be mounted e.g. on board a vehicle (not visible in the drawings).
  • the supply circuit may include the integration of source V1 and of driver 12 in one single circuit element, or a different arrangement of source V1 and circuit 12.
  • the use of shunt resistor R2 according to the ways better detailed in the following is by no way mandatory, because the corresponding function may be integrated in the functions of circuit 12.
  • reference to a possible mounting together with a reflector and/or in a vehicle headlamp is merely exemplary.
  • One or more embodiments may be based on the fact that, in lighting sources as the presently exemplified LED source, it is possible to take advantage of the colour shift of the emitted light radiation (i.e. of the wavelength around which, with a more or less clearly defined peak, light radiation is emitted), which may take place due to the variation of parameters such as the current (e.g. the average current) through lighting source L and/or the temperature (e.g. the junction temperature).
  • the current e.g. the average current
  • the temperature e.g. the junction temperature
  • LED lighting sources such as AlInGaP-based sources (which may be used e.g. in retrofit lamps in order to obtain a yellow light radiation emission around 595 nm), it is possible to observe:
  • measurements that have been carried out in the same conditions as above on the previously identified LEDs lead to the detection of a peak of flux increase by 250% with a pulsed current supply, the pulses having a length of 1 ms in the case of a rated current of 350 mA, with a maximum allowable direct current of approximately 1 A.
  • a pulsed operating mode may be employed by increasing the peak current and at the same time by reducing the pulse duty cycle down to a value of 2 A, i.e. approximately twice the current in direct current operation, while observing in this case too a clear variation of the emission wavelength.
  • lighting source L may include a plurality of LEDs (e.g. four) D1 - D4 with a ceramic package as described above, the power source V1 operating with direct voltage, e.g. with a voltage amounting to 13.5 Volt.
  • shunt resistor R2 may have a value of 10 Ohm.
  • the overall voltage drop across LEDs D1 to D4 may amount approximately to 11.4 V, the current flowing through the LEDs amounting approximately to 0.21 A and resistor R2 dissipating approximately 0.45 W.
  • circuit 12 may respond to a signal A adapted to indicate e.g. a warning/alarm condition, as detected e.g. by a vehicle control system (e.g. to signal that an airbag has been activated or any external control signal).
  • a vehicle control system e.g. to signal that an airbag has been activated or any external control signal.
  • At the reception of signal A circuit 12 may operate by switching the operating condition of source L from the previously described first lighting mode (e.g. with direct current supply) to a second lighting mode (e.g. with pulsed supply).
  • first lighting mode e.g. with direct current supply
  • second lighting mode e.g. with pulsed supply
  • circuit 12 may include a square (rectangular) wave oscillator, adapted to act by increasing the voltage and therefore the current applied to the LEDs, e.g. by applying on source L (on diodes D1 to D4, in the presently considered example) a pulsed voltage which meets the specifications of the LEDs constituting source L, so as to produce such a change of the LED current (and, at least indirectly, the temperature thereof) as to induce a shift in the emission wavelength.
  • source L on diodes D1 to D4
  • a pulsed voltage which meets the specifications of the LEDs constituting source L, so as to produce such a change of the LED current (and, at least indirectly, the temperature thereof) as to induce a shift in the emission wavelength.
  • circuit 12 may be a square (rectangular) wave oscillator, adapted to supply a pulsed voltage of 35 Volt, with a current value of about 2 A, so that the resistor R2 may dissipate around 2W.
  • a shift may be brought about, from a first lighting operating mode with a (direct) current of 200 mA, from a wavelength around 595 nm to a wavelength around 604 nm, i.e. a 9 nm-shift, between the first and the second lighting modes.
  • Such a shift may be perceived by an observer as a colour change of source L from yellow to a red, rapidly blinking light.
  • the compliance with the specifications of the LEDs of the source e.g. D1 to D4 enables a reversible operation, the possibility being given of switching operation from the first (e.g. direct current) operating mode to the second (e.g. pulsed) operating mode and then of returning to the first operating mode (e.g. when the alarm condition revealed by signal A has ceased) without jeopardizing the performance of source L.
  • switching from the first operating mode to the second (alarm) operating mode may be irreversible.
  • this may be envisaged if in the pulsed alarm operating mode the duty cycle and/or the current exceed maximum operating values allowable in the long term. In this way, it is possible to achieve even higher wavelength shifts, e.g. so that the colour of the light radiation emitted by lighting source L changes even more clearly, e.g. from yellow to a very bright green, by taking into account the thusly induced temperature variation.
  • a pulsed operation with current values up to 2.5 A may lead to a significant temperature change, so that the wavelength goes from 595 nm (first direct current operating mode) to around 615 nm, which corresponds to a quite bright red light.
  • such an irreversible operating mode may moreover enable the emission of such a light radiation for a limited period of time, which however covers a sufficiently long time window, which may be chosen so that it corresponds to the duration of an alarm condition which varies from lamp to lamp.
  • One or more embodiments may find application together with LED lighting sources employing technologies other than previously quoted AlInGaP chips, with the consequent option to operate between wavelength values, and with wavelength value shifts, which are different from the above.
  • One or more embodiments may be applied both to direct emission LEDs and to non-direct emission LEDs, e.g. phosphor-converted LEDs.
  • One or more embodiments may find application in OLED (Organic LED) technology, because also these LEDs have features of emission wavelength variation which depend on current and temperature.
  • OLED Organic LED
  • the presently considered operating modes may all be lighting modes, i.e. operating modes wherein source L actually performs a lighting action, e.g. of a vehicle headlamp.
  • a pulsed operation (e.g. with PWM driving) may be used in order to compensate for undesirable wavelength shifts, which may be induced by room temperature.
  • PWM driving e.g. with PWM driving
  • An example is the case, already discussed in the foregoing, of mounting light radiation source L in a vehicle headlamp, where significant temperature variations may take place e.g. because of a change of outdoor temperature (e.g. winter/summer) .
  • a PWM driving may be used in order to cause the emission wavelength shift to correspond (only) to the desired shift, e.g. as a function of the reception of signal A.
  • Pulse Width Modulation PWM
  • One or more embodiments may use regular shapes such as sinusoidal, triangular, gaussian, or non-regular shapes deriving from the overlap, e.g., of several sinusoidal waveforms, or of waveforms of the same kind with different shape.
  • Switching from the first operating mode to (at least) one second operating mode may be brought about by acting on the waveform, the width, the frequency, the offset of the supply current applied to source L.
