Optical system for uniform illumination of a target area

An optical system adapted to direct towards a target area light rays from a light source having an optical axis, the system comprising:

• a reflector defining an optical chamber comprising an upper opening, a lower opening, a chamber axis extending between the upper opening and the lower opening, and a reflective inner surface, wherein the upper opening is adapted to receive the light rays and the reflective inner surface is adapted to direct the light rays towards the lower opening;
• and
• a lens extending within a lens plane oriented at a first angle relative to the chamber axis, the lens comprising:
• a light input face;
• a light output face opposite the light input face;
• a first set of prisms provided on the light input face and configured to bend the light rays such that the light rays exit the lens at an exit angle relative to the optical axis and in a direction towards the target area;
• and
• a second set of prisms oriented at a second angle relative to the first set of prisms and configured to spread the light rays laterally relative to the target area.
