Definitions

  • the invention relates to an LED light module for a motor vehicle or for a headlight for a motor vehicle, wherein the light module comprises a lens and an LED light source.
  • Such an LED light source may be constructed of one or more light emitting diodes (LEDs) arranged to form a "common" light beam.
  • LEDs light emitting diodes
  • An initially mentioned light module consists essentially of one (or more) LED light source (s), e.g. in the form of a high-power light-emitting diode, and a lens, can be used to generate a light distribution which contains light components above the HD line in the generated light image.
  • the thus realized light function (example: high beam, object lighting, ...) can be activated only in special driving situations, just then, if an object for illumination in front of the vehicle is present or the situation allows the switching on of the high beam.
  • Such a light module is only rarely active, depending on the type (high beam, object lighting, ...) of the light module often only a few minutes per hour.
  • Such a light module can therefore not be included in the design of the night design of the vehicle or the vehicle headlamp, i. E. the visible to the outside of the light module area appears at night, when the light module is not activated, dark, which is often perceived as unpleasant.
  • a light module mentioned in the introduction that according to the invention in the light exit direction between the LED light source and the lens a lens is arranged, wherein the lens at least one opening for the direct passage of at least a portion of the emitted light from the LED light source and wherein the direct component emerging through the opening of the lens the light emitted by the LED light source is projected via the lens to produce a light function in the area in front of the motor vehicle.
  • the lens can be homogeneously illuminated, whereby the light from the primary light source can pass unhindered through the opening in the lens, so that the main light function is not affected.
  • the LED light source is embodied as a primary light source whose substantially entire emitted, relevant luminous flux exits through the opening of the lens to produce the light function.
  • Relevant luminous flux is to be understood as the luminous flux which can enter via the light entry surface of the lens; This luminous flux thus includes those light rays which are emitted within the aperture angle of the lens from the LED light source.
  • a light-emitting diode has a specific emission behavior, so that usually a portion of the light rays - unless it is deflected - is emitted in directions at angles which are greater than the opening angle of the lens, so that this light does not enter the lens and thus is basically usable for the light function.
  • Light from the LED light source, which is radiated at a larger angle than the opening angle no longer represents "relevant" luminous flux.
  • At least one further LED light source is provided as a secondary light source, which is arranged with respect to the opening of the lens so that the light emitted by the secondary light source is emitted substantially to the lens so that substantially no Luminous flux of the secondary light source exits through the opening of the lens.
  • Such an LED light source can be constructed from one or more light-emitting diodes (LEDs), which form a "common" light beam.
  • the secondary light source can then - see below - be constructed from one or more such LED light sources.
  • a diffusing screen (diffuse disk) which is illuminated by one or more additional LED light sources.
  • an axis by the LED light source of the primary light source and the opening of the lens forms the optical axis and that the at least one LED light source of the secondary light source is outside the optical axis.
  • the at least one LED light source of the secondary light source against the light exit direction, with respect to the primary Light source is arranged offset to the rear.
  • the secondary light source comprises two or more LED light sources.
  • the LED light source of the primary light source and the at least one LED light source of the secondary light source can be controlled separately, so that the primary light source and the secondary light source can be switched on and off independently.
  • the secondary light source of the light module in the vertical direction below a horizontal plane which runs for example by the LED light source of the primary light source, n LED light sources and above the Horizontal plane has m LED light sources, where m ⁇ n.
  • the lens of the light module is mostly viewed from angles above this horizontal, it is advantageous if the number of LEDs in the lower area is increased, since this area is imaged in the angular range above the horizontal and so a more visually appealing illumination of the lens can be achieved.
  • the optical axis of the lens does not necessarily have to pass through the LED or, in the case of several LEDs, through its geometric center, the horizontal plane does not necessarily have to pass through the primary LED light source, but can also be defined by the lens Direction may be shifted, which also changes the position of the image (angle).

  • the size of the opening in the lens is dependent on the distance of the disc to the LED light source of the primary light source and can be derived from the opening angle of the lens.

  • the uniform illumination of the lens is essentially defined by 3 parameters: distance of the secondary LED light source (s) to the lens, number of light sources and arrangement of the light source about the optical axis of the lens, preferably in one or more planes behind the lens, to achieve the necessary distance of the secondary LED light sources to the lens.
  • the homogeneity of the lens is directly proportional to the number of secondary LED light sources and the distance of the secondary LED light sources to the lens, wherein a uniform distribution of the secondary LED light sources is advantageous.
  • the limiting factor for these parameters is the space available for the light module. This results in certain optimized variants.
  • edge of the opening of the lens to the rear, directed in the direction of the primary light source is tapered, e.g. trapezoidal in order to be optimally adapted to the beam path of the boundary rays of the primary light source (boundary rays are those light rays which impinge on the latter at the opening angle of the lens).
