1. An LED spotlight, preferably for white light, having:
an LED module (5) having several LED chips (7, 7′) on a carrier (6), wherein a color conversion layer is applied in direct contact with the LED chips, a cooling body (3) which is in thermal contact with the LED module (5), a reflector (2) which laterally surrounds the LED chips (7, 7′), and a light mixing chamber (40) which is arranged within the reflector (3) and laterally surrounds the LED chips (7, 7′), wherein the light mixing chamber base surface (50) and the reflector bottom (60) are located on the same plane wherein the lateral side (80) of the light mixing chamber (40) facing toward the LED chips (7, 7′) is formed to be reflective, or reflective and scattering, wherein the light mixing chamber (40) is open at a top thereof, and wherein a cylinder attachment (4), which is integrally formed with the reflector bottom and laterally encloses the light mixing chamber (40), extends away from the reflector bottom (60) towards the top of the light mixing chamber. |
