The lamp has a bulb (2) and reflector (3) mounted horizontally, directing light onto a flat mirror (4) that reflects the light vertically downward. The reflector has an opening at the center to allow access to the bulb. The inner part of the reflector produces a parallel beam along the optical axis of the reflector, while the outer periphery produces a beam converging toward the optical axis. |
