Abstract
A lighting apparatus for a gaming machine cabinet comprising: a spot light source which emits light relative to a central emission axis; and a translucent diffuser spaced from the spot light source, the diffuser comprising an inner portion located so as to intercept light emitted along the emission axis and an outer portion spaced from the emission axis, the inner and outer portions arranged such that the diffuser prevents transmission of more light in the region of the inner portion than in the region of the outer portion.
Claims46
A lighting apparatus for a gaming machine cabinet comprising:
- a spot light source within the gaming machine cabinet which emits light relative to a central emission axis;
- and
- a translucent diffuser spaced from the spot light source, the diffuser comprising an inner portion located so as to intercept light emitted along the emission axis and an outer portion spaced from the emission axis, the inner and outer portions arranged such that the diffuser prevents transmission of more light in the region of the inner portion than in the region of the outer portion, wherein the inner portion is circular and the outer portion comprises a plurality of arms extending from the inner portion.

- and an artwork carrying portion arranged to be illuminated by light emitted from the light source, wherein the inner portion is circular and the outer portion comprises a plurality of arms extending from the inner portion.
A lighting apparatus for a gaming machine cabinet comprising:
- a light within the gaming machine cabinet source which emits light in a brightness pattern;
- and
- a substantially planar translucent diffuser spaced from the light source and formed to transmit incident light from the light source proportionally to the inverse of the brightness pattern, whereby the light output by the lighting apparatus is substantially uniform in the region of the diffuser, wherein the diffuser has a circular inner portion and an outer portion comprising a plurality of arms extending from the inner portion.
