For example, it is possible to reduce the power consumed by the bulb, which proportionally increases the life of this bulb. You can also change the hash frequency to change the color emitted by the bulb. For example, it is possible to switch between a first service frequency and a second service frequency to change the illumination color. With such a power supply, two illumination colors can be obtained for a given light intensity.

  • the power supply generally has intrinsically a cos ⁇ much lower than 1, because of the use of coils and capacitors.
  • a compensation circuit makes it possible to bring the cos ⁇ of the power supply closer to a value of 1. The power supply of the lamp can thus respond to different legislations concerning disturbances and harmonics of the current.
  • the cos ⁇ compensation circuit is connected to the rectified voltage terminals of the rectifier circuit D3.
  • the cos ⁇ compensation circuit can perform a measurement of the shape of the rectified current via a transformer 43. Depending on the shape of the measured current, the cos ⁇ compensation circuit, actuates the switch 44 to smooth the current.

  • the control unit can then be set to interrupt the power supply of the bulb when a shock or vibration exceeding a predetermined threshold are detected. It is for example possible to interrupt the lamp momentarily during the passage of vehicles generating significant vibrations. It can thus increase the life of the lamp and the socket.
  • the shock or vibration sensor is known per se. These functions can be implemented in a manner known per se. It is best to connect the bulb socket or the switching power supply to the lamp housing via one or more appropriate silent-blocks or dampers. The bulb is thus better insulated from any external vibrations. It is then preferable to mount the vibration sensor 44 at the damped zone of the lamp, for example inside the control circuit 35 or at another suitable place in the switching power supply 19.
