A lighting module including a housing with a cavity enclosed with a light-emitting surface and in which an LED is mounted connectable to a power source and possibly also to a control circuit. Between the LED and the light-emitting surface is arranged a transparent optical filter having an upper surface and a lower surface. The upper surface is adapted for the passage of a minor portion of light from the cavity of the housing to the light-emitting surface and, at the same time, the upper surface is adapted to reflect most of the light from the cavity of the housing back to the lower surface. On the lower surface of the transparent optical filter facing the LED is arranged a spatial optical structure adapted to scatter light from the cavity of the housing onto the upper surface and at the same time is adapted to scatter light reflected from the upper surface back to the spatial optical structure opposite the bottom of the cavity of the housing and possibly also opposite the side surfaces of the cavity of the lighting module.
