1. A track lighting system, comprising
a power track being connectable to an electric supply and arranged to be mountable to a surface in a mounting direction, B, said mounting direction, B, being towards and orthogonal to said surface and
a first light-emitting diode, LED, module being electrically and mechanically connectable to the power track, and wherein the first LED module comprises
a first LED light source arranged to emit first LED light,
a first housing, wherein the first housing at least partially encloses the first LED light source, and wherein the first housing comprises a first collimator having a first principal axis, E, and arranged to collimate the first LED light in a first main direction, D1,
a second LED light source arranged to emit second LED light, wherein the second LED light is different from the first LED light,
a second housing, wherein the second housing at least partially encloses the second LED light source, wherein the second housing comprises a second collimator having a second principal axis, F, and arranged to collimate the second LED light in a second main direction, D2,
wherein the first collimator is tiltable with respect to a normal, C, of a plane, A, wherein the normal, C, is in an opposite direction to the mounting direction, B, such that the first principal axis, E, forms a first angle, α, with respect to the normal, C,
wherein the second principal axis, F, of the second collimator is fixed with respect to tilt at a second angle, β, with respect to the normal, C, and
wherein the track lighting system further comprising a blocking mechanism configured to avoid the first housing blocking the collimated second LED light.
