- the largest
- the brightest
- the most evenly illuminated
- the thinnest and first flexible light sheet
- a standard thicknesses range of 3mm to 10mm (thicker if required)
Our customers use Addlux LED light sheet as a backlighting component in a variety of other LED illuminated end-products. These include:
- adding an opal diffusion sheet for making bespoke LED light panels
- adding a graphic to create permanent displays
- adding a frame for making high quality, ultra-slim LED light boxes
- backlighting translucent materials, such as frosted, opaque or stained glass, onyx stone, etc.
- any number of space-saving backlighting applications
- forming shapes or wrapping round columns, corners, etc
In summary, we are confident that Addlux holds a pre-eminent position in the marketplace for high-tech, high quality LED light sheet. Furthermore, we offer you a guarantee of an excellent customer service, including speedy quotes, quick and reliable deliveries and outstanding technical support for any and every reason, including assistance in the development and prototyping of your development products. Call one of our lighting experts on 0333 800 1828 or send us an email if wish for any further information about us or advice on how best to use our light sheet components. Better still, test us and ask us for a quote. *Note: As our LED light sheet is not intended to be used as a stand-alone product, but to be integrated into other applications we class them as components.

High TechnologyAn Addlux light sheet comprises essentially the LED light source, a light guide (LG), a reflector sheet, and the power supply/driver/transformer (PSU), see Illustration 1. Depending on the application, the light sheet is then used to backlight a graphic (light panel) or a diffuser sheet. The light guide distributes the light from the LED strips, for a one-sided light guide the reflector sheet serves to return the light back through the light guide, graphic or diffuser sheet that may be opalescent glass or acrylic or translucent materials, such as ground glass, onyx.

The LED Light SourceThe basic element of any LED lighting is the LED itself. The light source we use for manufacturing our LED light sheet are high light intensity, low energy LED strips. We develop and manufacture our own LED strip products in-house using highest quality components, thus ensuring a consistent high-quality product. The LED strips are embedded in or edge-mounted on a high grade acrylic sheet to form the light guide (see Illustration 2). The brightness of the light sheet is governed by the placing of the LED strips on one, two or all four sides, depending on the width and shape of the light sheet (see Illustration 3). Where higher levels of brightness are specified we use even more powerful LEDs or mount multiple rows of LED strips.
Illustration 4 The unique grid matrix and dot matrix patterns machined on the light guide ensure even light distribution across its entire surface regardless of its dimensions and location of the LEDs.
We can supply light sheet with light from LEDs of widely different colour temperatures – 6000K or 5300K (cool white); 4000K (moonlight white); 3000K (warm white); single colour RGB (red/green/blue) or colour-changing RGB.
The Addlux Light Guide – A Wonder of High Technology giving Optimum Brightness and Evenness of IlluminationThe function of the light guide (LG) is to diffuse and distribute light from the LEDs evenly across its surface. Addlux is a trend-setter in light sheet technology. Whereas our competitors machine evenly spaced grooves, we have perfected a novel technique that ensures the evenness of light distribution across the entire surface of an LED light sheet regardless of its size and shape. Even brightness ultimately determines the quality of your end-product, and often the functionality and success of the product/application for which you will use it. Depending on the size, thickness, arrangement of the LED strips and the specification for your order, we laser-machine one surface of an acrylic sheet with a unique pattern of grids or dots (see Illustration 3). The grids are made up of 3D grooves and the dots are 3D pits. The pattern is computer-generated and controlled, it is unique to the size and shape of the light sheet, varying in the spacing and the density of the grooves or dots across the width of the light sheet, see Illustrations 3. We use three different approaches to form the unique patterns on the light guide – dot matrix, grid matrix and micro-dot matrix. Light sheet with the micro-dot pits have the highest brightness but are presently restricted in size to 1.5m x 1.5m. See Table 1 for brightness properties and maximum size availability.
|Reflecting Matrix||Dimension||Max. size||Brightness (average)||Application|
|Dot||3D||3m x 2m||~2000 lux||Indoor & Outdoor|
|Grid||3D||4.8m x 2.7m||~ 2000 lux||Indoor & Outdoor|
|Micro-Dot||3D||1.5m x 1.5m||25% brighter||Indoor & Outdoor|

Even BrightnessUsing our high technology approach in the manufacture of the light guide we manage to achieve an unparalleled evenness of brightness exceeding 90% across an Addlux LED light sheet of any size or shape even on our largest sized light sheet. Actual brightness measurements on a 3.05m x 1.52m light sheet are shown in Illustration 5.
