Abstract (en)
A projection lighting device (5) includes a light source unit (51) having at least two frames each with a light emitting diode (512) and a reflection member (513) is connected to the light source unit. The reflection member includes at least two polyellipsoid surfaces (5131) so as to reflect the light beams from the light emitting diodes. The reflection member has two first flat surfaces (5132) in two ends thereof. A lens (52) is connected to the light source unit and has two second flat surfaces (524) in two ends thereof. The light source units can be arranged to be close to each other, the reflection member and the lens each have two flat surfaces such that the lighting device is compact in size.
