The lighting system 1 includes a light emitting unit 4 including light emitting diodes, and a securing member 5 for securing the light emitting unit 4 to a head of a healthcare worker. The radiation of light from the light emitting unit 4 eliminates the need for a shadowless lamp. When the light emitting unit 4 is fixed to the head, the light emitting unit 4 moves with the movement of the healthcare worker, and furthermore, when the healthcare worker moves his or her head, the direction of light radiation can be changed as desired. The use of an auxiliary lighting unit 6 and a camera 22 can provide safe surgery.
