[Problem] To provide an illumination system with which a visual effect is provided such that it is possible to give an appearance of expanding depth on the far side of a wall face, even if a person stands directly in front thereof. [Solution] An illumination system (100) comprises a light source (130), and a reflection board (120) that provides a reflection face that reflects illumination light from the light source (130). The reflection lace of the reflection board (120) is a processed reflection face in which are disposed a plurality of grooves which are very narrow parallel straight lines or parallel curved lines with respect to a flat plane. A support body (110) supports the light source (130) facing and in close proximity to the processed reflection board of the reflection board (120). Light points appear, arranged perpendicularly in the center of the reflection board (120) facing the light source. The formation locations of virtual images of each of the light points are formed further in the depth direction from the processed reflection board the further apart they are vertically, and thus a viewer has the sense of viewing a light beam track which is formed when a horizontal plane, which seemingly expands horizontally in the depth of the wall face, is illuminated, and has the sense of viewing an expanding space in the depth direction of the wall face.

An enclosure or display cabinet for displaying heated objects (such as a food display module or container) using heat-sensitive lighting is disclosed herein. The heat-sensitive lighting may be, for example, an LED lighting unit. LED lighting is inefficient and tends to degrade or fail when operating at higher temperatures. However, LED lighting may be preferred as it is typically more energy efficient than other lighting options (such as incandescent bulbs). The lighting unit includes a thermally insulated space, shelf, or gap for housing the lighting and a system for reducing heat generated by the display or the lighting unit.
