Abstract

A light diffuser tube (10) for an LED array suitable for use with electronic gaming machines includes a mounting portion (11), a diffusion portion (12) and a body portion (13). The body portion (13) consists of side walls (14 and 15) connected by a base (16) to define therebetween an elongated passageway for receiving communication cables and associated electrics.

Claims

1. A light diffuser tube for an led array comprising a mounting portion, a:

diffuser portion and a body portion between the mounting portion and the diffuser portion.

2. A light diffuser tube according to claim 1 wherein the body portion comprises a pair of spaced apart wide walls, a base connecting the side walls and a throat opposite the base for receiving a printed circuit board upon which the LED array is arranged with the electrical cables and associated circuitry being located within the body portion and the LED array being located in the diffuser portion.

3. A light diffuser tube according to claim 2 wherein the throat is defined by flanges directed inwardly from the side walls.

4. A light diffuser tube according to claim 3 wherein the diffuser portion has a base having inwardly directed flanges which with the flanges of the body portion define elongated slots adapted to receive the side edges of a printed circuit board.

5. A light diffuser tube according to claim 1 wherein the inside surface of the diffuser portion is formed by lenticular elements.

6. A light diffuser tube according to claim 1 wherein the mounting portion has inwardly directed flanges which are spaced from the underside of the base of the mounting portion to define a pair of elongated slots which are adapted to receive outwardly directed flanges of a miniature top hat DIN rail.
