The combination of light and glass can produce many wonderful effects that not only enhance aesthetics, but also improve the function of the glass. Take for example a frameless glass balustrade; in certain conditions it may not be visually obvious where the extents are, like at night time. Gentle lighting of the edge (Edge Lighting) can enhance safety while at the same time create a magical effect.
When lighting glass, various factors need to be taken into account. The most obvious being what part of the glass is going to be lit. Illuminating the entire pane calls for a different technique to lighting either just the edge or sections of it. Light spread and diffusion to gain a uniformed output may also be a consideration.
Generally glass is completely transparent and light will simply pass through it straight to the opposing edge, to get light from the surface it is necessary to defect the glass to permit the rays of light to transmit to the out face. This can be achieved in a number of ways which are discussed in the Glass options section of the ideas centre.
The light source also needs consideration. LED Strips are a more common option though cold cathode tubes can also be used. Not only is the choice of light source important but attention may also be given to the colour, control over colour and the desired effect required. Individually addressable RGB LED’s can provide the greatest scope for most applications allowing anything from static to mood lighting and change of ambience at the touch of a button.
The physical constraint of the lighting source and how it will be mechanically linked with the glass is also worth a mention. A plastic or mechanical extrusion is the most common method adopted though, in the case of a frameless shower cubical, other options can be necessary, for example embedding the light source in the adjoining wall. For balustrades with handrails, the light source can often be concealed within the rail itself.
An alternative to using a strip of LED’s can be to use a Light Engine in conjunction with an acrylic tube, though cost effective, this is can be very inefficient and is rarely used.
Vision Group can offer high-quality aluminium profiles designed specifically for lighting glass. We can also provide a total solution from the LED-lighting and suitable glass, to the controller and wiring. We can also advise on installation whether it be floor mounted, suspended or on the wall or ceiling.
Typical Glass Lighting Applications:
• Facade and Entrance illumination
Beam angles, power requirements and optimum spacing of the LED also need consideration to avoid light wastage and provide the most consistent and efficient pattern of light. Please contact us if you would like further information or have a project in mind that you think we could assist with. |
