  • Patent number: 4507714
    Abstract: A pair of relatively high wattage tungsten-halogen lamps are mounted directly below a pair of spaced-apart apertures in a forward portion of a horizontal deck that separates the case into a display compartment and a utility cabinet. Forced air ventilation is provided in the utility area to cool the lamps. A ceiling mirror in the display compartment reflects the light onto the display deck. Front and rear windows disposed below and on opposite sides of the ceiling mirror lie outside of the light pathways to prevent glare. Side mirrors and a diagonal front mirror also reflect light onto the merchandise in the display area while avoiding the windows.
