There is provided a luminaire (1) and a collimating optics (2) for LED lights (5). The collimating optics (2) comprises a reflection collimator (3) having a first aperture (7) for allowing incoming light from a LED light (5) to enter the collimator (3) and a second aperture (9) for allowing outgoing light to exit the collimator (3). The reflection collimator (3) further has a wall (15) with a reflective inner surface for guiding the incoming light from the first aperture (7) towards the second aperture (9). A first convex lens (11) is arranged at a distance from the first aperture (7) for refracting the incoming light and a second convex lens (13) is arranged at the second aperture (9) for refracting and collimating the outgoing light. With the disclosed collimating optics the collimating capability is improved without the size of the optics being increased. |
