Abstract

There is disclosed a showcase comprising an illumination apparatus which can stably be held by a simple structure and which can illuminate the inside of a display chamber effectively without any unevenness. The illumination apparatus provided in the showcase comprises a shade member constituted of a light-transmitting front wall positioned on the side of the light emitting surfaces of LED elements, and a back wall positioned on the side of a substrate provided with the LED elements, the front wall comprising a curved portion having an arc-like section and a pair of flat portions extended continuously from both ends of the curved portion to intersect with the back wall at an acute angle, corner portions where the flat portions intersect with the back wall being a pair of engaging portions; and a holder provided with a plurality of engagement portions and the like with which the engaging portions are disengageably engaged.

Claims

1. A showcase in which the inside of a display chamber disposed in a main body is illuminated by an illumination apparatus,

wherein the illumination apparatus comprising LED elements, a shade member in which the LED elements are received, and a holder attached to the main body to hold the shade member,

the shade member comprising a light-transmitting front wall positioned on the side of the light emitting surfaces of the LED elements, and a back wall positioned on the side of the substrate provided with the LED elements,

the front wall comprising a curved portion disposed so as to face the LED elements and having an arc-like section, and a pair of flat portions extended continuously from both ends of the curved portion to intersect with the back wall at an acute angle, corner portions where the flat portions intersect with the back wall are a pair of engaging portions,

the holder is provided with engagement portions with which the engaging portions are disengageably engaged, and a plurality of engagement portions with which at least one of the engaging portion is engaged are provided.

2. The showcase according to claim 1, wherein the shade member comprising a hollow shade main body comprising a front wall and a back wall, and end caps attached so as to close both end openings of the shade main body in a longitudinal direction,

the outer surface of each of the end caps is provided with a depressed groove which opens in at least the end of the shade main body on a back wall side, and the depressed groove is provided with drawing holes through which wiring lines from the substrate are drawn.
