## Abstract

A lighting assembly includes a heat dissipating member, a socket and an LED light module removably coupleable to the socket. The socket has one or more electrical contact elements accessed via one or more slots in the socket such that they are protected from inadvertent human contact. The LED light module includes an LED lighting element and one or more electrical contact members that can extend into the one or more slots to releasably contact the one or more electrical contact elements, and establish an operative electrical connection, when the LED light module is coupled to the socket. One or more resilient members of the LED light module or socket gradually compress as the LED light module is axially inserted at least partially into the socket and then rotated relative to the socket such that the one or more electrical contact members move along the one or more slots into contact with the one or more electrical contact elements of the socket.

## Claims

### Claim 1

A lighting assembly, comprising:
a socket attachable to a heat dissipating member, said socket comprising one or more electrical contact elements accessed via one or more openings in the socket, said one or more openings extending along at least a portion of a circumference of the socket; and
an LED light module removably coupleable to the socket, comprising:
an LED lighting element; and
one or more electrical contact members configured to extend into the one or more openings in the socket to releasably contact the one or more electrical contact elements of the socket when the LED light module is coupled to the socket, said LED light module electrical contact members configured such that they will establish an operative electrical connection with the socket; and
one or more resilient members of the LED light module or socket configured to apply a force between the LED light module and a least a portion or an element of the heat dissipating member when the LED light module is axially inserted at least partially into the socket such that the one or more electrical contact members extend into the one or more openings and when the LED light module is rotated relative to the socket, following said axial insertion, such that the one or more electrical contact members move along the one or more openings to thereby contact the one or more electrical contact elements of the socket.

### Claim 2 (depends on 1)

The lighting assembly of claim 1, wherein said one or more electrical contact members of the LED light module extend from a surface of the LED light module.

### Claim 3 (depends on 1)

The lighting assembly of claim 1, wherein the one or more electrical contact members of the LED light module comprises a pair of electrical contact posts, each of the electrical contact posts configured to releasably contact one of the electrical contact elements of the socket to establish an electrical connection between the LED light module and the socket.

### Claim 4 (depends on 1)

The lighting assembly of claim 1, wherein the heat dissipating member comprises a thermally conductive housing.

### Claim 5 (depends on 1)

The lighting assembly of claim 1, wherein the one or more electrical contact members comprise electrical contact strips.

### Claim 6 (depends on 1)

The lighting assembly of claim 1, wherein the one or more resilient members comprise a plurality of leaf springs.

### Claim 7 (depends on 1)

The lighting assembly of claim 1, wherein the one or more resilient members comprises a resilient member disposed between a distal end of the LED light module and a proximal end of the LED light module.

### Claim 8 (depends on 1)

The lighting assembly of claim 1, wherein the one or more resilient members comprises a compression spring.

### Claim 9 (depends on 8)

The lighting assembly of claim 8, wherein the compression spring is a coil spring.

### Claim 10

A lighting assembly, comprising:
a heat dissipating member;
a socket attachable to the heat dissipating member, said socket comprising one or more electrical contact elements accessed via one or openings in the socket; and
an LED light module removably coupleable to the socket, comprising:
an LED lighting element; and
one or more electrical contact members configured to extend into the one or more openings in the socket to releasably contact the one or more electrical contact elements of the socket when the LED light module is coupled to the socket, said LED light module electrical contact members configured to establish an operative electrical connection with the socket; and
one or more resilient members of the LED light module or socket configured to gradually compress as the LED light module is axially inserted at least partially into the socket and then rotated relative to the socket such that the one or more electrical contact members move along the one or more openings into contact with the one or more electrical contact elements of the socket, the one or more resilient members configured to apply a force between the LED light module and a least a portion or an element of the heat dissipating member during one or both of said axial insertion and/or rotation of the LED light module relative to the socket.

### Claim 11 (depends on 10)

The lighting assembly of claim 10, wherein said one or more electrical contact members of the LED light module extend from a surface of the LED light module.

### Claim 12 (depends on 10)

The lighting assembly of claim 10, wherein the one or more electrical contact members of the LED light module comprises a pair of electrical contact posts, each of the electrical contact posts configured to releasably contact one of the electrical contact elements of the socket to establish an electrical connection between the LED light module and the socket.

### Claim 13 (depends on 12)

The lighting assembly of claim 12, wherein each of the pair of electrical contacts provides a positive or negative electrical contact.

### Claim 14 (depends on 12)

The lighting assembly of claim 12, wherein each of the pair of electrical contacts provides a positive or negative electrical contact.

### Claim 15 (depends on 10)

The lighting assembly of claim 10, wherein the heat dissipating member comprises a thermally conductive housing.

### Claim 16 (depends on 10)
