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.
Claims20
A translucent diffuser for an electronic gaming machine for diffusing light from a spot light source, the diffuser comprising an inner portion adapted to be located so as to intercept light emitted along an emission axis by the light source and an outer portion spaced from the emission axis, the inner and outer portions arranged such that, in use, the diffuser prevents transmission of more light in the region of the inner portion than in the region of the outer portion.
A translucent diffuser as claimed in claim 12, wherein the distance is about 15 mm.
A translucent diffuser for an electronic gaming machine for diffusing light emitted by a light source in a brightness pattern, the diffuser being substantially planar 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.
