Abstract
An operating theatre lamp with a main reflector (13) which illuminates the area of the operation (11) with a convergent main light beam (12) and an auxiliary reflector (15) can be arranged inside the main reflector to deflect a part of the used light beam (16) at a steeper angle to the site of the operation (11).
Claims13
An operating theater lamp comprising:
- a light source;
- a main reflector including at least two diametrically opposed concave mirror regions positioned to reflect the light from the light source and converge it onto a site to be illuminated;
- an auxiliary reflector comprising at least two diametrically opposed auxiliary mirror regions disposed between said light source and said main reflector, said auxiliary mirror regions being movable relative to the main reflector between an inoperative position in which said auxiliary mirror regions are displaced completely outside of the light path from the light source, and an operative position in which said auxiliary mirror regions are located relative to the light source to reflect a portion of the light and concentrate it on the site at a greater angle than the angle at which a remaining portion of light reflected from said main reflector converges on the site.
