Abstract
Abstract A multi-layer LED assembly which is used as a replacement light for equipment used in manufacturing environments. On each layer of the multi-layer assembly, there are multiple LEDs which are mounted perpendicular to a base. The base is used to provide electrical and mechanical connection to a socket. The LED assembly is constructed in a manner which allows the LED assembly to be inserted into a socket of a lighting fixture and then mechanical and electrical connections are provided without requiring rotation of the LED assembly. Electrical connection is by permanently attached wires between the base and the LEDs. The base is rotatable within a predetermined angular range which is sufficient to provide a proper mechanical and electrical connection without putting strain on the permanently attached electrical wires. The LED assembly may utilize multiple layers of LEDs, with each layer itself having multiple LEDs. The LEDs in each layer are mounted in a direction perpendicular to the base which results in light emanating in a direction perpendicular to the base.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
124 words
An assembly for insertion into a socket, said assembly having at least one layer of LEDs mounted on at least one board, said assembly comprising: a) a base adapted to be installed in the socket by rotation of the base; b) an axle coupled to said base which passes through said at least one board onto which is mounted a layer of LEDs; c) an insulating layer including a hole through which said axle passes and a slot; d) a knob coupled to said axle at an end opposite said base and adjacent to said insulating layer, said knob having a pin adapted to engage said slot and move back and forth within said slot as said knob is rotated clockwise and counter clockwise.
Claim 2
Dependent Claim
124 words
An assembly for insertion into a socket, said assembly having at least one layer of LEDs mounted on at least one board, said assembly comprising: a) a base adapted to be installed in the socket by rotation of the base; b) an axle coupled to said base which passes through said at least one board onto which is mounted a layer of LEDs; c) an insulating layer including a hole through which said axle passes and a slot; d) a knob coupled to said axle at an end opposite said base and adjacent to said insulating layer, said knob having a pin adapted to engage said slot and move back and forth within said slot as said knob is rotated clockwise and counter clockwise.
