Abstract

The invention relates to a lighting device, comprising:
a reflector (20) including at least one reflecting surface (21); and a light source unit (30) disposed in the vicinity of the reflector and comprising:
a main body (32) having a first outside surface (38) and a second outside surfaces (39), wherein each of said first and second outside surfaces is inclined with reference to the other; and
a plurality of first light emitting diodes (31) disposed on the first outside surface and a plurality of second light emitting diodes disposed on the second outside surface so that said first and second light emitting diodes are configured to emit light towards the reflector.
