## Abstract

An LED illuminating showcase includes a frame unit and a lighting unit. The frame unit includes bottom and top seat covers, and a transparent tubular shell extending from the bottom seat cover to the top seat cover and defining a display space with the seat covers. The lighting unit includes opposite terminal subunits respectively disposed in the seat covers, a connecting bar connected fixedly to an inner surface of the tubular shell, having two ends that abut respectively against the seat covers, and that are connected respectively and electrically to the terminal subunits, and an LED module embedded in the top seat cover for illuminating the display space.

## Claims

### Claim 1

A Light Emitting Diode (LED) illuminating showcase comprising:
a frame unit having
a bottom seat cover,
a top seat cover that is spaced apart from said bottom seat cover, and
a transparent tubular shell that extends from said bottom seat cover to said top seat cover and that cooperates with said bottom seat cover and said top seat cover to define a display space thereamong; and
a lighting unit including
opposite terminal subunits that are respectively disposed in said bottom seat cover and said top seat cover,
a connecting bar that is connected fixedly to an inner surface of said transparent tubular shell, that has two ends abutting respectively against said bottom seat cover and said top seat cover and connected respectively and electrically to said terminal subunits,
an LED module that is embedded in said top seat cover and that is connected electrically to a corresponding one of said terminal subunits in said top seat cover for illuminating said display space,
a power source that is embedded in said bottom seat cover and that is connected electrically to a corresponding one of said terminal subunits in said bottom seat cover, and
a switch that is disposed on said frame unit for turning on or off said LED module.

### Claim 2 (depends on 1)

The LED illuminating showcase of claim 1, wherein said LED module of said lighting unit includes a circuit board that is disposed in said top seat cover, and a plurality of LEDs that are spaced apart from each other and that are disposed in said top seat cover for illuminating said display space.

### Claim 3 (depends on 2)

The LED illuminating showcase of claim 2, wherein said LEDs of said lighting unit are controlled by said switch to emit light of different brightness, colors and color temperatures.

### Claim 4 (depends on 1)

The LED illuminating showcase of claim 1, wherein each of said terminal subunits of said lighting unit includes a pin that extends retractably and outwardly of a corresponding one of said bottom seat cover and said top seat cover.

### Claim 5 (depends on 1)

The LED illuminating showcase of claim 1, wherein each of said bottom seat cover and said top seat cover has a circular groove engaged with a respective one of a bottom end and a top end of said transparent tubular shell, and a connecting groove engaged with a respective one of said two ends of said connecting bar, each of said terminal subunits being disposed in said connecting groove of the respective one of said top and bottom seat covers.
