Backlighting Translucent Surfaces

By | News | No Comments

Backlighting is the process of placing a source of light behind a translucent material to make it glow or light up. The old method of doing this was to create a light box with an internal white reflective surface and place the translucent material over this for illumination. This method was hit and miss depending on who was designing it, constructing it, and what source of light was used for the process. More often than not the translucent material ended up with hot spots across it, with those involved vowing never to attempt it again. Until now……

I’d like to introduce you to a product which has revolutionised the way backlighting is done……LumiSheet!

As a lighting consultant specialising in lighting designs for Superyachts and very high end domestic residences, backlighting translucent materials was always high on my list for creating beautifully illuminated spaces that evoke emotion, but it was always hindered by the tradespeople involved in creating the effect. LumiSheet takes away all of the guess work when backlighting, and makes it a simple repeatable process, because the LumiSheet is designed to emit a bright, even amount of light across the entire surface of the panel.

LumiSheet is the world’s first LED integrated edge-lit light panel that contains the LED’s in itself as a source of light, unlike the old style backlight units which use LED’s on the outside edge of the acrylic.

This patent technology makes it possible to produce frameless lighting panels of any shape, size and colour.

                              

LumiSheet is produced by combining high intensity LED’s with a patented 3D V-Cutting system which allows light to be transmitted uniformly and evenly across the acrylic surface.

So you can see there’s no need for space hungry light boxes to be incorporated into the design. Simply fix the LumiSheet panel to the structural substrate and position the translucent material directly over it. It’s that easy! The ability to backlight without the need for a light box is a real game changer when it comes to kitchen splash backs, island benches, bathrooms and the galley of yachts and motor yachts.

LumiSheet can be supplied with small fixing holes around the perimeter for screw fixing, or simply apply small dabs of silicon to the back of the sheet to adhere it into position. Either option makes the installation of the panel a simple quick process, compared to the old method of having to create calculated grid patterns of LED’s in a space hungry light box. Speaking with the electricians, cabinet makers and stone companies that have installed the LumiSheet into my lighting designs, they’ve all said the same thing when asked about the ease of its installation….”it’s a piece of cake”!

LumiSheet comes in a wide range of fixed white CCT’s (compared colour temperatures), 2700K, 3000K, 3500K, 4100K, 5300K, 6500K, and there’s even Lumisheet Duo, an adjustable colour temperature panel from 3300K – 6400K! So no matter what the colour of the translucent surface being illuminated is, there’s a colour temperature in the range to suit. For those of you who enjoy adding a splash of colour to your decor, there is an RGB and RGBW version also. The difference between the two options is RGB uses 100% RED, 100% GREEN & 100% BLUE to mix a poor quality white, whereas the RGBW option has a dedicated white LED chip providing a pure white which can be modulated from 1% – 100% and mixed with the RGB colours. If you don’t require white, then RGB is the option to go for.

Decorative and residential lighting are subjective experiences, and as such everyone has an individual idea about the level of brightness required for any given area, and LumiSheet is no different, so you’ll be happy to know the light panels are dimmable. The simplest way is to use one of our 12VDC Triac Dimmable Drivers found in our store. This PDV range of LED drivers take the dimming signal from a 240V mains dimmer and converts it into a 12VDC or 24VDC PWM signal for dimming LED strip and LumiSheet. I recommend the DIGINET Smart LED Dimmer for use with the Triac Dimmable Drivers as from bench tests it has out performed all other brands. Please use a licensed electrician for the installation of these.

Natural translucent stones are a gorgeous feature in any home, and when they’re backlit are enjoyable 24/7, plus they are a wonderful addition to a layered lighting design. So remember, the easiest way to backlight surfaces is with LumiSheet! Call us today for a free quote and our expert team will assist and liaise with your tradespeople to ensure the job is done right the first time.

NOTE: For use with extremely translucent materials, a gap of about 20mm may be required between the LumiSheet and the surface being illuminated. You can call or email your enquiry to us for quick clarification as to whether this applies to your translucent material.
