  • 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.
