Abstract

Vehicular lights that hold a bulb in a bayonet type socket are converted to receive light emitting diode assemblies that plug in with a simple translation motion instead of the push and then twist required for bayonet type connection. An adapter is provided along with an installation tool. The adapter fits onto the tool. The tool is inserted into the bayonet socket by a push and twist motion. The tool is the removed by a straight pull. The adapter has now converted the socket so that it can receive and properly connect any of a group of LED assemblies by simple translation of a plug on the assembly. Various light assemblies are disclosed including incorporating the external vehicle lens, and including a sonic element in the assembly to complement a back-up light.

Claims

1. An LED light assembly and connection adapter for installation in the bayonet socket of a motor vehicle, the bayonet socket having electrically conductive side walls with parallel slots in the side walls extending parallel to the long axis of the socket, the slots terminating in transverse arcs, and at least one electrical contact at the base of the socket, the improvement comprising:

a) an adapter including;

i) a male first portion having;

a cylindrical side wall and an insulated end wall;

a pair of opposed electrically conductive pins extending radially from the side wall adapted for insertion into the slots by first translation and then rotation for electrically engaging and holding onto the socket side walls;

at least one electrical contact on the end wall adapted for electrically contacting the at least one electrical contact at the base of the socket;

ii) a female second portion including;

a plurality of contacts adapted for secure electrical connection by translation to a unitary plug;

each of the contacts in the second portion being electrically connected either to one of the contacts in the end wall or to the pins;

b) a lamp assembly including;

i) a housing having a first face and a second face;

ii) an LED board assembly having a plurality of LED'"'"'s fixedly mounted thereon in a predetermined distribution, the LED board assembly being mounted in the housing with the lights shining outwardly from the second face;

iii) a unitary electrical plug attached by attachment means to the first face and extending outwardly therefrom, the unitary electrical plug being adapted for secure electrical connection of a plurality of contacts therein by translation into the female second portion of the adapter; and

iiii) electrical connection between each of the contacts in the unitary plug and certain of the LED'"'"'s for performing prescribed functions.

2. The improvement according to claim 1 further comprising:

a sonic element mounted on the LED board assembly connected to a contact on the plug for sounding an alarm in conjunction with a backup light on the board.

3. The improvement according to claim 1 further comprising means for adjusting the rotary angle of the first portion relative to the second portion of the adapter.

4. The improvement according to claim 1 further comprising an installation tool for inserting the adapter into the bayonet socket, the tool comprising:

a) an elongate shaft having first and second ends;

b) a handle at the first end for gripping and rotating;

c) a plug at the second end for secure insertion into the female second portion of the adapter with means for rotating the adapter within the bayonet socket.

5. The improvement according to claim 1 further comprising an external lens molded onto the second face of lamp assembly for mounting in place of the original vehicle lens.

6. The improvement according to claim 1 in which the attachment means is rigid.

7. The improvement according to claim 1 in which the attachment means is flexible.

8. A connection adapter system for installation in a bayonet socket, the bayonet socket having electrically conductive side walls with parallel slots in the side walls extending parallel to the long axis of the socket, the slots terminating in transverse arcs, and at least one electrical contact at the base of the socket, the adapter comprising:

i) a male first portion having;

a cylindrical side wall and an insulated end wall;

a pair of opposed electrically conductive pins extending radially from the side wall adapted for insertion into the slots by first translation and then rotation for electrically engaging and holding onto the socket side walls;

at least one electrical contact on the end wall adapted for electrically contacting the at least one electrical contact at the base of the socket;

ii) a female second portion including;

a plurality of contacts adapted for secure electrical connection by translation to a unitary plug; and

each of the contacts in the second portion being electrically connected either to one of the contacts in the end wall or to the pins.

9. The connection adapter system according to claim 8 further comprising an installation tool for inserting the adapter into the bayonet socket, the tool comprising:

a) an elongate shaft having first and second ends;

b) a handle at the first end for gripping and rotating;

c) a plug at the second end for secure insertion into the female second portion of the adapter with means for rotating the adapter within the bayonet socket by rotation of the handle.

10. The improvement according to claim 9 further comprising means for adjusting the rotary of the first portion relative to the second portion of the adapter.
