  • Lighting module, in particular for a vehicle lighting device and a vehicle lighting device
    Patent number: 11754242
    Abstract: 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.
