  • Patent number: 9263651
    Abstract: An LED package including a collimator body adapted to collect and/or reflect and/or focus light. An upper plane provided by the collimator body defines a mainly horizontal plane. At least one reflection surface is provided by the collimator body and is at least partially angled to the horizontal plane. The collimator body includes a recess for receiving a lighting element including a light emitting front face such that the reflection surface extends at least partially below the level of the front face in an assembled state. Due to the angle of the reflection surface with respect to the horizontal plane of the collimator body, a small light source and a high luminous flux at the same time are provided so that the luminance and the brightness of the LED package are increased.

  • Patent number: 8454216
    Abstract: It is provided a lamp assembly (10) for an automotive headlamp, comprising an LED (12) for emitting light rays, a housing (16), to which the LED (12) is detachably connectable, wherein the housing (16) comprises an entrance window (20) assigned to the LED (12), and a guiding element (22) for guiding the light rays passing through the entrance window (20), wherein the guiding element (22) is connected to the housing (16). Since the LED (12) is detachable connected to the housing (16) a defect LED (12) can by exchanged by only exchanging the LED (12) itself without exchanging the whole lamp assembly (10) including the housing (16) and the guiding element (22). Since the correct position of the bright/dark-cutoff may be provided by the entrance window (20) and/or the guiding element (22) only, a misalignment of a newly inserted LED (12) does not affect the correct position of the bright/dark-cutoff. The exchange of a LED (12) is facilitated and without affecting the correct position of the bright/dark-cutoff.
