  • the semiconductor light sources are hitherto predominantly inorganic, but in some cases organic light-emitting diodes.
  • Inorganic light emitting diodes consist of at least one light emitting diode semiconductor chip, short LED chip, and at least one, for example, molded by injection molding, the at least one LED chip completely or partially enveloping primary optics. Vehicle lights are also known in which pure LED chips are used without molded primary optics.
  • TCT Through Hole Technology
  • SMD Surface Mounted Device
  • COB Chip On Board
  • THT LEDs are a well-known type of inorganic light-emitting diodes. They are also referred to as leaded light-emitting diodes, as they consist of an at least in a desired emission transparent encapsulation, e.g. in the form of an encapsulation or an encapsulation, which includes a LED chip with a first electrical connection, for example in the form of an anode terminal connecting bonding wire and connected to a second electrical connection, for example in the form of a cathode terminal, LED chip. From the encapsulation protrude only the designated as little legs wires of the first electrical connection and the second electrical connection as the anode and cathode terminals of the THT-LED.
  • the second electrical connection embodied, for example, as a cathode connection can in this case be provided with a cup mentioned above, in which the LED chip is arranged.
  • the bonding wire leads from the example executed as an anode terminal first connection from outside the cup coming to the LED chip.
  • SMD LEDs SMD LEDs for short, are another well-known type of inorganic light-emitting diode.
  • SMD LEDs consist of a leadframe with at least one mounting surface for at least one LED chip and electrical connection surfaces.
  • the leadframe is made of a plastic body with at least one of them At least one mounting surface free recess partially encapsulated.
  • the electrical connection surfaces of the leadframe are also kept free as the electrical connections of the SMD LED for later surface mounting.
  • the at least one LED chip is arranged and electrically contacted at the bottom of the at least one recess extending to the at least one mounting surface. In this case, the LED chip is arranged on a first portion of the leadframe connected to at least one first electrical connection area.
  • a bonding wire connects the LED chip to a second portion of the leadframe, which in turn is connected to at least one second electrical pad.

  • the bonding wire forming the second electrical connection of the COB LED is likewise connected to a second conductor track of the illuminant carrier, e.g. electrically connected by soldering or welding.
  • LEDs are used uniformly for both, unless explicitly stated otherwise.
  • Outstanding properties of LEDs compared to other, conventional light sources of bulbs are a much longer life and a significantly higher light output with the same power consumption.
  • LEDs have lower power consumption compared to other light sources. This can be when using a or several LEDS as a light source of a light source, for example in a vehicle lamp, the load of a vehicle provided for power supply electrical system of a vehicle can be reduced, along with savings in energy consumption of the vehicle.
  • LEDs have a much longer life than other, for use in a vehicle lamp candidate light sources. Due to the longer service life, among other things, the lower failure rate increases the operational safety and, concomitantly, the quality of the vehicle lamp.
  • OLED organic light-emitting diode

  • the thickness or, in other words, the thickness of the layers is on the order of about 100 nm. Typically, it is 100 nm to 500 nm, depending on the structure.
  • OLEDs typically encapsulated with an inorganic material, especially glass.
  • OLEDs do not require monocrystalline materials. Compared to LEDs, OLEDs can therefore be produced using inexpensive thin-film technology. As a result, OLEDs make it possible to produce flat light sources which on the one hand have a very thin appearance and, on the other hand, have a particularly homogeneous appearance when used as a luminous surface visible through the lens of a vehicle lamp.
  • LEDs have a forward voltage, which makes it possible to arrange a plurality of LEDs in series or in series with an LED string and to apply the vehicle electrical system voltage as a supply voltage to the LED string at normal, prevailing in driving operation with the engine running vehicle electrical system voltage. Due to the higher forward voltage of OLEDs, that number of OLEDs which can be connected in series or in series with an OLED strand and which, while maintaining the light emission, makes it possible to apply the vehicle electrical system voltage prevailing when the internal combustion engine is running as the supply voltage to an OLED line with LEDs.
  • semiconductor light sources have the disadvantage that they do not tend to darken just like conventional light sources due to their functional principle and short reaction time, for example when the electric starter of an internal combustion engine of a vehicle is actuated when the light is on and the vehicle electrical system voltage therefore drops when the voltage applied to them falls below their respective forward voltage or when the vehicle electrical system voltage drops below a minimum supply voltage resulting from the sum of the forward voltages of the semiconductor light sources connected in series with a semiconductor light source train.
  • the number of semiconductor light sources arranged in series with a semiconductor light source strand has been reduced to a number in which the maintenance of an electrical voltage at each of the semiconductor light source voltage is still maintained in the case of, for example, the operation of an electric starter of an internal combustion engine.
  • Strand arranged semiconductor light source is ensured above the forward voltage.

  • US 2007/108843 A1 is a power supply of series-connected semiconductor light sources of a vehicle intended for light bulbs known.
  • the power supply includes a constant current source and a bypass switch in parallel with each semiconductor light source and / or each pair of series-connected semiconductor light sources and / or each group of series-connected semiconductor light sources.
  • By opening and closing the respective bypass switch the individual semiconductor light sources and / or pairs of semiconductor light sources connected in series and / or groups of semiconductor light sources connected in series can be individually illuminated or switched off as required.
  • An electrical control of the bypass switch detects faults of one or more semiconductor light sources and switches off faulty semiconductor light sources by bridging. The electrical control can illuminate redundant semiconductor light sources to replace faulty semiconductor light sources.
  • the electrical control can dim one or more semiconductor light sources as needed.
  • the bypass in certain operating conditions, as would prevail in a vehicle application, for example, with lowered vehicle electrical system voltage, at least a portion of the LEDs remains dark.
  • This is not a satisfactory solution to the described impairment of traffic safety, because a part of the semiconductor light sources of a provided for fulfilling a light function in a vehicle lamp bulb with multiple semiconductor light sources remain dark as light sources with lowered board voltage and thus the light emission of the light source is reduced overall and at least in individual Spaces of the entire, to be covered jointly by all semiconductor light sources solid angle range is absent.
  • the lighting means may have a current limiter arranged in series with the LEDs, accompanied by the disadvantage of high power loss at high supply voltage.
  • the lighting means may comprise a microcontroller and activation switches arranged in series with the LEDs and / or bypass switches arranged parallel to one or more of the LEDs. Outputs of the microcontroller open and close the switches to turn the LEDs on when the power supply voltage by closing the activation switch all shut down at too high supply voltage by opening the activation switch or to bridge at low supply voltage by closing the bypass switch part of the LEDs.
  • the microcontroller can compare a detected supply voltage and / or a supply current intensity and / or a temperature with one or more threshold values and, depending thereon, completely disconnect the LEDs from the supply voltage or bypass a portion of the LEDs or switch on all the LEDs.
  • this is not a satisfactory solution of the described impairment of traffic safety, because a part of the LEDs of a provided for fulfilling a light function in a vehicle lamp bulb with multiple LEDs as light sources with lowered vehicle electrical system voltage dark remain and thus the light emission of the lamp is reduced overall and at least in individual spatial directions of the entire, to be covered by all LEDs together solid angle range is absent.

  • the method further provides for comparing the monitored and detected vehicle electrical system voltage or the voltage proportional thereto with a voltage threshold which is at least equal to or higher than the sum of the forward voltages of the at least two semiconductor light sources of the group.
  • a voltage threshold value is at least equal to or higher than the sum of the forward voltages of the at least two semiconductor light sources of a group.
  • a comparison of the vehicle electrical system voltage or the voltage proportional thereto with a first voltage threshold which is at least equal to or higher than the sum of the forward voltages of the at least two semiconductor light sources of a first group takes place. which has the lowest number of semiconductor light sources of the groups with different numbers of semiconductor light sources, and there is a comparison of the vehicle electrical system voltage or voltage proportional thereto with a second voltage threshold which is at least equal to or higher than the sum of the forward voltages of the at least three semiconductor light sources a second group having a higher number of semiconductor light sources than the first group. If further, for example third, fourth and so on groups with an even higher number of semiconductor light sources are present, then additional comparison with correspondingly higher third, fourth and so on voltage threshold values takes place.

  • the method provides for the semiconductor light source train to be at least two in Series electrically interconnected or arranged semiconductor light sources of the group or for multiple groups each of the semiconductor light source strands from at least two series-electrically connected or arranged semiconductor light sources per group to apply to the vehicle electrical system voltage or proportional voltage, all electrically connected to a semiconductor light source strand or arranged semiconductor light sources are current-carrying and emit light.
  • the fact that at least one semiconductor light source strand is acted upon by the vehicle electrical system voltage or the voltage proportional thereto refers to the fact that the semiconductor light sources per group are electrically connected in series to a semiconductor light source strand when the monitored and detected on-board electrical system voltage or this proportional voltage is equal to or higher than the voltage threshold, but the lighting means may comprise one or more groups of semiconductor light sources, the semiconductor light sources then each electrically connected in series to a semiconductor light source strand in series and corresponding to the number of groups Number of semiconductor light source strands in turn electrically connected in parallel to each other with the vehicle electrical system voltage or this proportional voltage are applied.

  • the method also provides for each of the two semiconductor light source sub-strands to be supplied with the vehicle electrical system voltage or the voltage proportional thereto.
  • the method provides, in parallel to interconnect the semiconductor light source sub-strands of at least one semiconductor light source and equally to apply to the vehicle electrical system voltage or this proportional voltage when the monitored and detected vehicle electrical system voltage or this proportional voltage is lower than the voltage threshold.
  • a supply voltage which is higher than the sum of the forward voltages of the semiconductor light sources assigned to a subgroup is thus applied to the semiconductor light source sub-strands. This ensures that even with lowered vehicle electrical system voltage or lowered, this proportional voltage, as prevails, for example, during operation of an electric starter of an internal combustion engine of a vehicle, all semiconductor light sources of the light source remain active and thereby emit light. At the same time, it is ensured that the brightness of the radiated light is the same when the vehicle electrical system voltage or this proportional voltage is lower than with normal vehicle electrical system voltage or this proportional voltage. This contributes to a significant increase in traffic safety.
  • An additional advantage results from the high utilization of resources, since both in operation with lowered vehicle electrical system voltage or this proportional voltage, as well as normal vehicle electrical system voltage or this proportional voltage all semiconductor light sources of the light emit light and no semiconductor light source remains dark. Another advantage is that by switching between with the normal vehicle electrical system voltage or this proportional voltage applied semiconductor light source strand and with the lowered vehicle electrical system voltage or this proportional voltage acted upon, parallel-connected semiconductor light source sub-strands occurring in operation power loss is the lowest possible.

  • a result of the comparison can optionally be assigned to one or the other circuit state, or, for example, can be assigned alternately once to one and then to the other circuit state in a hysteresis-like manner, to increase the stability of the switching.
  • the method may further provide for increasing, for example doubling, the current flowing through the semiconductor light sources of one or more groups when the monitored and sensed vehicle electrical system voltage or voltage proportional thereto is lower than the voltage threshold. As a result, required brightness values can be easily achieved.
  • the invention can be realized by switching from, for example, three LEDs connected in series with one LED string to two parallel LED sub-strings with two LEDs in series, with a lower strand instead of one LED a corresponding series resistor is inserted.
