Abstract
Exemplary embodiments provide a lighting system for a transparent LCD having opposing vertical edges, the system having a mullion lighting assembly positioned adjacent to each vertical edge of the transparent LCD, each mullion lighting assembly having sidewalls defining a center channel. A plurality of LEDs are positioned along the sidewall of each mullion assembly and on a side of the sidewall that opposes the center channel. The LEDs are preferably placed in conductive thermal communication with the sidewall and preferably have a quantum dot film positioned over each LED. A fan is preferably positioned to draw cooling air through the center channel.
Claims20
A lighting system for a transparent LCD having opposing vertical edges, the system comprising:
- a mullion lighting assembly positioned adjacent to each vertical edge of the transparent LCD, each mullion lighting assembly having sidewalls defining a center channel and;
- a plurality of LEDs positioned along the sidewall of each mullion lighting assembly and on a side of the sidewall that opposes the center channel, each LED having a central axis that is directed away from the transparent LCD;
- and
- a quantum dot film placed over each LED.
A lighting system for a first and second transparent LCD positioned side-by-side, the system comprising:
- a mullion lighting assembly positioned between the first and second LCDs and having sidewalls defining a center channel where a first portion of the sidewall is adjacent to the first LCD and a second portion of the sidewall is adjacent to the second LCD;
- a first plurality of LEDs positioned along the first portion of the sidewall and having a central axis that is angled away from the first LCD;
- a second plurality of LEDs positioned along the second portion of the sidewall and having a central axis that is angled away from the second LCD;
- a first quantum dot film placed over the first plurality of LEDs;
- and
- a second quantum dot film placed over the second plurality of LEDs.
A lighting system for the door of a display case containing several retail products, the door having a transparent LCD positioned behind a front glass where the LCD has a pair of vertical edges, the system comprising:
- a mullion lighting assembly positioned adjacent to each vertical edge of the transparent LCD, each mullion lighting assembly having sidewalls defining a center channel;
- a plurality of LEDs positioned along a sidewall of each mullion lighting assembly and on a side of the sidewall that opposes the center channel, each LED is placed in conductive thermal communication with the sidewall and has a central axis aimed towards the retail products;
- and
- a quantum dot film placed between the LEDs and the retail products.
