Abstract
The disclosed embodiments relate to a light guide () and a luminaire () including such a light guide (). The light guide () guides light emitted in a first direction () from a light source () comprising at least one light emitting diode (). The light guide () directs a major part of the light in a second direction (), wherein the first direction () is not equal to the second direction (). The light guide () comprises an upper part () having a shape of a cone, and a center axis () of the upper part () is in the first direction (). The light guide () can be used with reflectors () that have originally been manufactured for use with high intensity discharge lamps or halogen lamps but because of the light guide (), the reflectors () can be used together with light sources () in the form of at least one light emitting diode ().
