US Patent 10123637 Illuminating merchandise displayed at a display and dispensing apparatus

A light fixture is placed in an apparatus that displays and dispenses merchandise at a point-of-purchase located adjacent a display shelf. The apparatus includes a retainer plate that secures the apparatus to the display shelf. A light source is located in a receptacle having an arm that is extended beneath the retainer plate, between the retainer plate and the display shelf. A ridge on the arm extends upwardly into a groove in the retainer plate to lock the receptacle and, consequently, the light source in position to illuminate merchandise displayed along the display shelf.
