ABSTRACT:
A lighting device includes a light channel disposed in a wall or door of a treatment chamber. A light source cooperating with the light channel is disposed outside of the treatment chamber and provides light beams along a first direction. First and second reflectors are disposed in the light channel to reflect respective portions of the light beams toward the treatment chamber so as to enter the treatment chamber through a transparent area in the wall or door. The second reflector extends further in a second direction, which is transverse to the first direction, than the first reflector, such that the second portion of the light beams reaches the second reflector in an unhindered manner. The first and second reflectors have reflective surfaces thereon which are configured differently in the second direction and a third direction transverse to the first direction in order to prevent mutual shadowing.
