| 摘要 |
The invention relates to a lighting device (1) comprising a housing (8) with a light source connector for a LED (11) and a reflective collimator (3) and a refractive collimator (9) as well as to a method for their manufacture. The reflective collimator (3) comprises a plurality of reflective segments (4, 4′, 5, 5′, 6, 6′, 7, 7′), which are spaced apart from each other by means of air slits suitable for dissipation of heated air. The segments (4, 4′, 5, 5′, 6, 6′, 7, 7′) are adapted to reflect laterally emitted light generated by the light source (11) towards a direction which is substantially parallel to said main direction. Lighting devices according to this invention may have a compact design and an improved dissipation of the heat generated by the LEDs. |
