FIELD: physics.
SUBSTANCE: lighting device (1) includes several lighting sources (4) and one reflecting system, meanwhile the lighting sources (4) are located in front of the reflecting surface of the reflecting system and includes several lighting devices, located around an output hole (10) of the reflecting system. The light beam from the lighting sources (4) due to reflection is deflected towards the reference direction of radiation of the lighting device (1) by means of the reflecting system. The lighting device is fitted with the first reflecting section (2) and the convex second reflecting section (5), the first and second reflecting sections are matched to each other so that the basic light ray can be formed due to that the light from the lighting sources (4) first at first strikes the second reflecting section (5), and then the first reflecting section (2) and leaves from the lighting device towards the reference direction of radiation.
EFFECT: increasing power.
