Abstract: Profiles for shadowless reflector for operating lighting, wherein the operating lighting includes a front and a rear shade assembled together while the front shade has an opening for projecting the light rays, and the rear shade is mounted over the opening; the lower edge of the reflector's opening in the front and the rear shades is fixed on the front transparent shade which has a handle at the edge thereof while a socket for bulbs is installed over the front transparent shade; the bulb is enclosed by a heat absorbing glass; the light rays received by the reflector are focused on the front transparent shade and are projected; the longitudinal tangent of the reflector in the longitudinal direction consists of at least two connecting datum curves, and the connecting datum curves has the same tangent slope rate at the connecting point; each datum curve reflects the light rays well-distributed to the focusing datum plane; The datum curve of the reflector near the end point of the middle of the reflector reflects
