Surgical lighting must balance various needs of a user: the light must be bright, but not too thermally hot； directed at a target, but not shining elsewhere； be robust, yet compact. Often much of these myriad needs must be accomplished by ever small illumination elements placed into devices requiring ever lower profiles. However, current surgical illumination options require the use of bulky lighting elements if the desire target is to be illuminated or, conversely, use weaker lighting elements for sleeker designs.
