DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 3, 4 and 5, the preferred embodiment of the showcase according to the present invention includes a frame unit 3 and a lighting unit 4.
The frame unit 3 includes a rectangular housing 31 having a front opening 311, a detachable transparent window plate 32 to cover the front opening 311 of the housing 31, and a plurality of magnetic fastening mechanisms 33 disposed between the housing 31 and the transparent window plate 32 for coupling removably the transparent window plate 32 with the housing 31.
The housing 31 further has a bottom plate 312, a top plate 313, two side plates 314 and a back plate 315. The bottom and top plates 312, 313 are parallel to each other, one of the side plates 314 interconnects respective right edges of the bottom and top plates 312, 313, and the other one of the side plates 314 interconnects respective left edges of the bottom and top plates 312, 313. However, the bottom, top and side plates 312, 313, 314 maybe formed as an integrated piece in other embodiments.
The front opening 311 is defined between respective front edges of the bottom, top and side plates 312, 313, 314. The transparent window plate 32 detachably covers the front opening 311. The back plate 315 is opposite to the transparent window plate 32, and interconnects respective rear edges of the bottom, top and side plates 312, 313, 314. The back plate 315 may be fixed or detachable, depending on different requirements. For example, a scene or trade mark picture is often used as a background while displaying a displayed item (for example, a car model 5) in the showcase, and therefore, it is easier to replace the background when the back plate 315 is detachable.
The top plate 313 of the housing 31 has a bottom surface formed with a plurality of lighting-unit grooves 34 that are spaced apart from each other, and the housing 31 further has an inner surface 310 formed with a cable groove 35 and a cavity 38 in spatial communication with the cable groove 35. The frame unit 3 further includes a cover plate 36 for covering the cavity 38 in a manner that the cover plate 36 is flush with the inner surface 310 of the housing 31, and a decorative layer 37 to cover the cable groove 35, the cover plate 36 and the inner surface 310.
The lighting unit 4 includes a top lighting subunit 41 connected to the top plate 313, a label plate holder 42 disposed on the bottom plate 312, a side lighting subunit 43 disposed inside the label plate holder 42, a switch 44 disposed externally on the housing 31, and a control unit 45 that is embedded in the cavity 38 of the housing 31 and that controls the top lighting subunit 41 and the side lighting subunit 43. In particular, the control unit 45 is operable to control an on/off operation of each of the top and side lighting subunits 41, 43 to switch on or off the corresponding one of the top and side lighting subunits 41, 43, and/or a light-controlling operation to control color, brightness and/or color temperature of light emitted by each of the top and side lighting subunits 41, 43 when the same is switched on.
The top lighting subunit 41 includes a plurality of light emitting diode (LED) bars 413, and a plurality of light holders 411 that respectively engage the lighting-unit grooves 34 and that are respectively mounted with the LED bars 413 for orienting light emitted from the LED bars 413 so as to provide indirect lighting toward the bottom plate 312. The top lighting subunit 41 further includes a plurality of reflective members 412 respectively disposed in the lighting-unit grooves 34 for reflecting the light emitted from the LED bars 413, and a plurality of diffusion filters 414 respectively covering the lighting-unit grooves 34. The light holders 411 are made of aluminum to reduce weight and improve heat dissipation. The diffusion filters 414, together with the indirect lighting from the LED bars 413, provide even and soft lighting and avoid reflected bright spots on the car model 5.
The label plate holder 42 has a hollow transparent holder body 421 disposed on the bottom plate 312 and mounted with the side lighting subunit 43 therein, a transparent label plate 422 attached to the holder body 421, and a connecting member 423 embedded in the holder body 421 and electrically connecting the side lighting subunit 43 to the control unit 45 through a cable 351 disposed in the cable groove 35.
At least a portion of the light emitted from the side lighting subunit 43 penetrates the holder body 421 toward the back plate 315, providing a secondary lighting in a different angle to show more details of the displayed car model 5 and increasing variety in displaying the car model 5.
In this embodiment, the label plate holder 42 is detachable. The connecting member 423 is configured to have magnetism, and is disposed on and protrudes from a bottom surface of the holder body 421, such that the label plate holder 42 may be firmly attached to the bottom plate 312 of the housing 31 which is made of metal. Alternatively, the connecting member 423 may be an electrical conductor, and the label plate holder 42 may further have additional pins or other means for fastening the label plate holder 42 to the bottom plate 312.
In conclusion, the top lighting subunit 41 provides a soft and even lighting to avoid reflected bright spots on the displayed item, and the side lighting subunit 43 is disposed inside the label plate holder 42 and provides lighting in a side angle whereas the label plate holder 14 of the conventional showcase 1 show in FIG. 1 is only used for holding a label plate. Therefore, the showcase according to the present invention provides light with relatively more variety, and is able to display more details of the displayed item. In addition, the transparent label plate 422 allows the light emitted from the side lighting subunit 43 to transmit therethrough for a relatively better visual appeal of the transparent label plate 422 and an enhanced overall displaying effect of the showcase. Moreover, by virtue of the lighting-unit grooves 34 and the cable groove 35, the lighting unit 4 is embedded in the housing 31 and thereby is hidden from view. Since the cover plate 36 covers the cavity 38 and the decorative layer 37 covers the cable groove 35, the covering plate 36 and the inner surface 310 of the housing 31, an overall appearance inside the housing 31 may be a smooth, un-segmented surface.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
