Optoelectronic module comprising an interlock feature

Abstract

An optoelectronic module comprising: a radiation-emitting device; a housing comprising a wall or walls laterally surrounding the radiation-emitting device; two or more terminals disposed on a surface of the wall or walls; a transparent substrate abutting the housing, the transparent substrate comprising an interlock feature; a control unit coupled to the two or more terminals, wherein the control unit is configured to: supply an electrical current though the interlock feature; monitor an electrical parameter associated with the interlock feature; wherein the terminals are arranged such that: when the transparent substrate is in a first orientation about an optical axis of the radiation-emitting device, the interlock feature is coupled to at least two of the two or more terminals and the optoelectronic module is operable to provide a field of illumination in a first illumination orientation; and when the transparent substrate is in a second orientation about the optical axis of the radiation-emitting device, the interlock feature is coupled to at least two of the two or more terminals and the optoelectronic module is operable to provide a field of illumination in a second illumination orientation different from the first illumination orientation.
