Patent ID: 11145191

Abstract:
A flash light module (1) can include a housing (30) carrying at least a visible flash light emitter (10) to emit a flash light beam along an optical axis (OA) and at least one additional emitter (20) emitting non-visible light arranged at a second distance (D2) perpendicular to the optical axis (OA), where position and orientation of the additional emitter (20) and at least the second distances (D2) are suitably adapted as well as the housing (30) is suitably shaped in order to enable the additional emitter (20) to emit non-visible light (22) along a non-visible light emitting direction (IRD), wherein the additional emitter (20) is adapted to emit the non-visible light (22) to the environment suitable to remote communicate to, preferably to remote control, external electronic devices (5) comprising corresponding receivers for the non-visible light (22). A mobile device (100) can include the flash light module (1) and a method to operate the mobile device (100).
