Arrangement for spot illumination

An arrangement for spot illumination, comprising:

• a tubular reflector having a reflective inner surface and comprising a first section having an entrance aperture and an exit aperture being larger than said entrance aperture, and a second section having an entrance aperture and an exit aperture being substantially identical in size, said entrance aperture of said second section being positioned adjacent said exit aperture of said first section;
• a light source array comprising a plurality of light sources arranged to emit light into said first section of said tubular reflector at the entrance aperture of said first section;
• and,
• an optical focusing element arranged proximate to said second section of said tubular reflector, wherein said first section, said second section, said light source array and said optical focusing element thereby are arranged to form a collimated beam of homogeneous color mixed light to be outputted at the exit aperture of said second section.
• wherein an optical axis is formed from said light source array towards said exit aperture of said second section and wherein said lens array is placed along said optical axis beyond said exit aperture of said second section of said tubular reflector.
