Claim Text:
1. A lighting system comprising: a securing unit having a head band adapted to be secured to the head of a healthcare worker; a main body fixed to the securing unit, and having a planar illuminating surface to which a light emitting diode configuring to illuminate an operative field of a patient during surgery is attached; a left lighting unit which has a planar illuminating surface and a plurality of light emitting diodes on the planar illuminating surface, is coupled directly to the main body and shares a first single-hinge mechanism having a vertically extending rotation axis to a portion of the main body, and is adapted to be located to a left side of the healthcare worker, and to which a light emitting diode configured to illuminate the operative field of the patient during surgery is attached; and a right lighting unit which has a planar illuminating surface and a plurality of light emitting diodes on the planar illuminating surface, is coupled directly to the main body and shares a second single-hinge mechanism having a vertically extending rotation axis to a portion of the main body, and is adapted to be located to a right side of the healthcare worker, and to which a light emitting diode configured to illuminate the operative field of the patient during surgery is attached; wherein: the left and right lighting units move relatively closer to each other or relatively further apart from each other by a rotation of each of the left and right lighting units about rotation axes of the corresponding first or second single hinge mechanisms; the illuminating surface of the left lighting unit and the illuminating surface of the main body are closely coupled with no gap therebetween along the first single-hinge mechanism, the illuminating surface of the main body and the illuminating surface of the right lighting unit are closely coupled with no gap therebetween along the second single-hinge mechanism, and the illuminating surfaces of the left lighting unit, the main body and the right lighting unit form a bended and still unified surface; and even under a condition that degrees of angles differ from each other by rotations of the left lighting unit and the right lighting unit, the illuminating surface of the left lighting unit; the illuminating surface of the main body and the illuminating surface of the right lighting unit are maintained coupled with no gap therebetween, and light illuminated from the illuminating surfaces illuminates the operative field of the patient by reflecting the light.
