The light power supply includes a supply input configured to electrically connect to the pair of metal contacts. A recess is formed on the housing and is free of metallic material. A contactless electrical power transmitter is disposed within the housing and adjacent to the recess. The contactless electrical power transmitter is electrically connected to the light power supply and configured to contactlessly transmit electrical power to a light bulb received in the recess. ## Claims ### Claim 1 A light coupler comprising: a housing; a base formed at an end of the housing and including a pair of externally facing metal contacts configured to electrically connect to an external power supply; a light power supply disposed within the housing, the light power supply including a supply input configured to electrically connect to the pair of metal contacts; a recess formed on the housing and free of metallic material; and a contactless electrical power transmitter disposed within the housing and adjacent to the recess, the contactless electrical power transmitter being electrically connected to the light power supply and configured to contactlessly transmit electrical power to a light bulb received in the recess. ### Claim 2 (depends on 1) The light coupler of claim 1, wherein the contactless electrical power transmitter is one of a coil transmitter or a capacitive plate transmitter. ### Claim 3 (depends on 2) The light coupler of claim 2, wherein the contactless electrical power transmitter is a coil transmitter having a spiral geometry that is one of Archimedean or polygonal in shape. ### Claim 4 (depends on 1) The light coupler of claim 1, further comprising a reed switch configured to prevent power from flowing to the contactless electrical transmitter unless the reed switch is aligned with an activation magnet from a light bulb received in the recess. ### Claim 5 (depends on 4) The light coupler of claim 4, wherein the housing has a longitudinal axis and the reed switch is spaced apart from the longitudinal axis. ### Claim 6 (depends on 1) The light coupler of claim 1, wherein a first of the pair of metal contacts is a metal thread formed on a sidewall of the base and a second of the pair of metal contacts is a metallic tip exposed at an end of the base. ### Claim 7 (depends on 1) The light coupler of claim 1, further comprising first and second wires that respectively electrically connect the pair of metal contacts to the light power supply. ### Claim 8 (depends on 1) The light coupler of claim 1, wherein the contactless electrical power transmitter is formed of at least one of graphene, carbon, borophene, carbon nanotubes, a conductive composite material. ### Claim 9 (depends on 1) The light coupler of claim 1, wherein the housing includes a first housing portion and a second housing portion, wherein: the base is formed at an end of the first housing portion, the light power supply is disposed within the first housing portion, the second housing portion includes the recess, and the contactless electrical power transmitter is disposed within the second housing portion. ### Claim 10 (depends on 1) The light coupler of claim 1, further comprising one of a metamaterial slab or a meta lens disposed within the housing between the contactless electrical power transmitter and the recess. ### Claim 11 A lighting assembly comprising: a light bulb including: one or more LEDs, a bulb housing containing the one or more LEDs, at least a portion of the bulb housing being at least partially transparent to one or more wavelengths of light emitted by the one or more LEDs, a non-metallic base formed at an end of the bulb housing, and a contactless electrical power receiver disposed within the non-metallic base and electrically connected to the one or more LEDs; and a light coupler including: a coupler housing, a base formed at an end of the coupler housing and including a pair of externally facing metal contacts configured to electrically connect to an external power supply, a light power supply disposed within the coupler housing, the light power supply including a supply input configured to electrically connect to the pair of metal contacts, a recess formed on the coupler housing and free of metallic material, and a contactless electrical power transmitter disposed within the housing and adjacent to the recess, the contactless electrical power transmitter being electrically connected to the light power supply, wherein when the non-metallic base of the light bulb is received in the recess of the light coupler, the contactless electrical power receiver and the contactless electrical power transmitter are aligned and physically separated from one another such that the contactless electrical power transmitter is enabled to contactlessly transmit electrical power from the light power supply to the contactless electrical power receiver, the contactless electrical power receiver being configured to provide the received electrical power to the one or more LEDs. ### Claim 12 (depends on 11) The lighting assembly of claim 11, wherein the contactless electrical power transmitter is one of an inductive coil transmitter or a capacitive plate transmitter and the contactless electrical power receiver is one of an inductive coil receiver or a capacitive plate receiver. ### Claim 13 (depends on 12) The lighting assembly of claim 12, wherein the contactless electrical power transmitter and the contactless electrical power receiver are each an inductive coil having a spiral geometry that is one of Archimedean or polygonal in shape. ### Claim 14 (depends on 11) The lighting assembly of claim 11, further comprising: a reed switch disposed within the coupler housing; and an activation magnet embedded or retained within the non-metallic base of the light bulb, wherein the light bulb and the light coupler are rotatable relative to one another between a first position and a second position, such that: when the light bulb and light coupler are in the second position, the reed switch and the activation magnet are aligned with one another and the reed switch enables the contactless electrical power transmitter to contactlessly transmit electrical power from the light power supply to the contactless electrical power receiver, and when the light bulb and light coupler are in the first position, the reed switch is not aligned with the activation magnet and prevents power from flowing to the contactless electrical power transmitter. ### Claim 15 (depends on 11) The lighting assembly of claim 11, wherein a first of the pair of metal contacts is a metal thread formed on a sidewall of the coupler base and a second of the pair of metal contacts is a metallic tip exposed at an end of the coupler base. ### Claim 16 (depends on 11) The lighting assembly of claim 11, wherein the contactless electrical power transmitter and the contactless electrical power receiver are each formed of at least one of graphene, borophene, carbon, carbon nanotubes, or a conductive composite material. ### Claim 17 (depends on 11) The lighting assembly of claim 11, further comprising one of a metamaterial slab or a meta lens disposed within the coupler housing between the contactless electrical power transmitter and the recess.
