Light chamber for door for gaming machine
View Patent ↗A belly door for a gaming machine includes a frame for receiving a sheet of artwork and a light reflective chamber having an open face which is located behind the frame when in a closed position. Clamping means are provided for clamping the artwork between the frame and the chamber. A recess extends along one edge of the chamber including sockets for receiving a fluorescent light tube when the chamber is in the closed position. A diffuser panel is disposed in the chamber behind the artwork located so as to be edge lit by the fluorescent light tube. The reverse face of the panel, which in use, faces the rear wall of the chamber defines a series of white opaque dots which in use, diffuse and direct the light in a forward direction perpendicular to the plane of the panel. The size of the dots in the panel increases with the distance of the dots from the fluorescent light tube. This arrangement ensures that the light panel produces a very evenly balanced lighting of the artwork.
1. A door assembly for a gaming machine comprising:
a frame for receiving a sheet of artwork;
a light reflective chamber having an open face which is hinged to and positionable behind the frame in a closed position;
a clamping member for clamping the artwork between the frame and the chamber;
a socket member for mounting an elongate light member on the frame adjacent an edge of the frame;
a recess extending along an edge of the chamber adapted to receive the elongate light member mounted in the socket member when the chamber is closed behind the frame; and
a diffuser panel disposed in the chamber behind the frame arranged to be edge lit by the elongate light member when the elongate light member is mounted in the socket member.
2. An assembly as claimed in claim 1 , further including a sheet of artwork and wherein the diffuser panel is disposed in the chamber behind the artwork.
3. An assembly as claimed in claim 1 , wherein the diffuser panel has a front face and a reverse and wherein the reverse face of the panel faces a rear wall of a chamber and defines a series of white opaque dots which diffuse and direct the light in a forward direction perpendicular to the plane of the panel.
4. An assembly as claimed in claim 3 , wherein the white opaque dots on the panel increase in size with the distance of the dots from the elongate light member.
5. An assembly as claimed in claim 1 , wherein the elongate light member is a fluorescent light tube having a diameter of about 7 mm.
6. An assembly as claimed in claim 3 , wherein the diffuser panel is supported by a series of ribs projecting from the rear wall of the light reflective chamber.
7. An assembly as claimed in claim 1 , wherein the clamping member includes a rotatable locking element defining wedge or cam surfaces co-operating with lugs defined on the frame adapted to clamp artwork between curved surfaces defined by the frame and the chamber respectively.
8. An assembly as claimed in claim 1 , wherein the socket member extends along a lower edge of the frame and the light tube is horizontally oriented.
9. A door assembly for a gaming machine comprising:
a frame;
a sheet of artwork located in the frame;
a light reflective chamber having an open face which is hinged to and positionable behind the frame in a closed position;
a clamping member for clamping the artwork between the frame and the chamber;
a socket member for mounting an elongate light member on the frame adjacent an edge of the frame;
a recess extending along an edge of the chamber adapted to receive the elongate light member mounted in the socket member when the chamber is closed behind the frame; and
a diffuser panel disposed in the chamber behind the frame and sheet of artwork arranged to be edge lit by an elongate light member mounted in the socket member, the diffuser panel having a front face and a reverse face wherein the reverse face of the panel faces a rear wall of the chamber and defines a series of white opaque dots which diffuse and direct the light in a forward direction perpendicular to the plane of the panel.
10. An assembly as claimed in claim 9 , wherein the dots of the panel increase in size with the distance of the dots from the elongate light member.
11. An assembly as claimed in claim 9 , wherein the elongate light member is a fluorescent light tube having a diameter of about 7 mm.
12. An assembly as claimed in claim 9 , wherein the diffuser panel is supported by a series of ribs projecting from the rear wall of the light reflective chamber.
13. An assembly as claimed in claim 9 , wherein the member for clamping includes a rotatable locking member, defining wedge or cam surfaces co-operating with lugs defined on the frame adapted to clamp artwork between curved surfaces defined by the frame and the chamber respectively.
14. An assembly as claimed in claim 11 , wherein the socket member extends along a lower edge of the frame and the fluorescent light tube is horizontally oriented.
