Lighting display assembly for a gaming machine
View Patent ↗A lighting display assembly for use with a display monitor includes a light guide plate and a light source. The light guide plate is formed from a single piece of material that is transparent to visible light. The light guide plate includes a center opening extending between its front and rear surfaces and defining an inner sidewall. The light source is configured to emit visible light and is positioned facing the inner sidewall so that light emitted therefrom passes through the inner sidewall and into the light guide plate. A pattern is formed in the light guide plate and positioned to be illuminated by the visible light emitted from the light source so that the illuminated pattern is visible through the front surface of the light guide plate. The lighting display assembly is mounted behind a display monitor and is sized to extend laterally beyond an outer peripheral edge of the display monitor such that the illuminated pattern is visible from in front of the display monitor.
1. A lighting display assembly comprising:
a light guide plate that is transparent to visible light, the light guide plate including a front surface, a rear surface and a center opening extending between the front surface and the rear surface and defining an inner sidewall;
a light source operable to emit visible light, the light source being positioned facing the inner sidewall so that light emitted therefrom passes through the inner sidewall and into the light guide plate;
a film being positioned on the rear surface, comprising a pattern to be illuminated by the visible light entering the inner sidewall of the light guide plate, and producing a visible effect of the pattern through the front surface of the light guide plate; and
a controller operable to controllably activate and deactivate the light source.
2. The lighting display assembly of claim 1 , wherein the film comprises an optical diffusion film.
3. The lighting display assembly of claim 1 , wherein the pattern is a speckled pattern, and wherein the visible effect is a speckled effect.
4. The lighting display assembly of claim 1 , wherein the film is optically bonded with the light guide plate.
5. The lighting display assembly of claim 4 , wherein the film comprises a non-light-diffusing surface and a light-diffusing surface, and wherein the non-light-diffusing surface is optically bonded with the rear surface, with the light-diffusing surface facing away from the rear surface.
6. The lighting display assembly of claim 1 , wherein the film is operable to redirect at least a portion of the visible light entering the inner sidewall of the light guide plate towards the front surface of the light guide plate.
7. A gaming machine comprising:
a cabinet;
a display monitor supported by the cabinet and having an outer peripheral edge;
a light guide plate that is transparent to visible light, and sized to extend laterally beyond the outer peripheral edge of the display monitor, the light guide plate including a front surface, a rear surface and a center opening extending between the front surface and the rear surface and defining an inner sidewall;
a light source operable to emit visible light, the light source being positioned facing the inner sidewall so that light emitted therefrom passes through the inner sidewall and into the light guide plate;
a film being positioned on the rear surface, comprising a pattern to be illuminated by the visible light entering the inner sidewall of the light guide plate, and producing a visible effect of the pattern through the front surface of the light guide plate and adjacent the display monitor; and
a controller operable to controllably activate and deactivate the light source.
8. The gaming machine of claim 7 , wherein the film comprises an optical diffusion film.
9. The gaming machine of claim 7 , wherein the pattern is a speckled pattern, and wherein the visible effect is a speckled effect.
10. The gaming machine of claim 7 , wherein the film is optically bonded with the light guide plate.
11. The gaming machine of claim 10 , wherein the film comprises a non-light-diffusing surface and a light-diffusing surface, and wherein the non-light-diffusing surface is optically bonded with the rear surface, with the light-diffusing surface facing away from the rear surface.
12. The gaming machine of claim 7 , wherein the film is operable to redirect at least a portion of the visible light entering the inner sidewall of the light guide plate towards the front surface of the light guide plate.
13. A lighting display assembly comprising:
a rear panel having a panel center opening;
a light guide plate that is transparent to visible light, the light guide plate including a front surface, a rear surface and a center opening extending between the front surface and the rear surface and defining an inner sidewall, the light guide plate overlying the rear panel with the panel center opening being aligned with the center opening of the rear panel;
a light source operable to emit visible light, the light source being positioned facing the inner sidewall of the light guide plate so that light emitted therefrom passes through the inner sidewall and into the light guide plate;
a film being positioned on the rear surface, comprising a pattern to be illuminated by the visible light entering the inner sidewall of the light guide plate, and producing a visible effect of the pattern through the front surface of the light guide plate; and
a controller operable to controllably activate and deactivate the light source.
14. The lighting display assembly of claim 13 , wherein the film comprises an optical diffusion film.
15. The lighting display assembly of claim 13 , wherein the pattern is a speckled pattern, and wherein the visible effect is a speckled effect.
16. The lighting display assembly of claim 13 , wherein the film is optically bonded with the light guide plate.
17. The lighting display assembly of claim 16 , wherein the film comprises a non-light-diffusing surface and a light-diffusing surface, and wherein the non-light-diffusing surface is optically bonded with the rear surface, with the light-diffusing surface facing away from the rear surface.
18. The lighting display assembly of claim 13 , wherein the film is operable to redirect at least a portion of the visible light entering the inner sidewall of the light guide plate towards the front surface of the light guide plate.
