<p>The mirror reflector is for built-in lights with asymmetrical light distribution, so as to give even illumination of vertical surfaces. It is round in shape, with parts (4a-4k) having a stepped profile with their upright faces inclined to the vertical. The angle of inclination first decreases, starting from the inside of the reflector (1), in stages from step to step until the vertical is reached, and then increases again in relation to the latter from step to step in the negative direction.</p> |
