Abstract

In-built lights for glass building components comprise electroluminescent lights as foils on a carrier plate or are directly imprinted onto a carrier material or onto the glass closing cover.

Description

glass bricks have been known for decades as components that are used in building facades, as well as used in interior construction. Your transparency creates optical lightness and thus sets architectural accents in the Construction.

Next the heavy and relatively complex to build glass blocks made of real glass, light glass bricks have also been made for some time Artificial glass manufactured by tongue and groove connection also by non-specialists can be set up easily. These new glass blocks are mainly used in interior construction, e.g. for partitions, room dividers, Cloakrooms, shower partitions and counter constructions.

The lightweight glass block consists of a translucent plastic base in Shape of a square or rectangular ring that represents the thickness of the glass block and a tongue and groove formation all around having. This tongue and groove design enables simple plugging together the glass blocks. Due to the protrusion on all sides of the base body and tongue and groove formation in the center are created in the assembled one Glass brick wall between the basic bodies vertical and horizontal Spacer joints that are used as continuous supply channels can be. On this basic body are two caps each made of synthetic glass, which both the base body, as well as the spacing joints cover. The color and structure of these caps determine the look of the glass block.

Around additional To be able to create effects with the glass blocks, the use of Light wanted.

The The object of the invention is to create a uniformly radiating Install glare-free light in glass blocks. In addition, that may Illuminants used do not become hot in continuous operation and should be able to operate with low energy consumption. With usual Bulbs can these demands are not being implemented.

The solution according to the invention achieved with electoluminescent lights (EL lights).

It These are EL pigments that are screen-printed a carrier material be applied. By applying an AC voltage, the EL pigments stimulated to emit light. It is a very even, produces glare-free light. The luminance (brightness) is determined by the Operating voltage and frequency regulated. With the appropriate EL pigments, or pigment mixtures, can be used in many light colors and so also white Generate light. Thanks to multi-layer EL pigment printing in RGB colors, can with an EL light, by appropriate control, all light colors generated, including Color change games. By electronic control can whole area or on segmented surfaces different modes can be operated; such as. Flashing, running light and dimming effects. There is also the possibility, without much effort, Cut contours from or into the EL lights, which are then sharp limit the lamp.

By the uniform luminance the EL lights are particularly suitable for backlighting foils, Posters, colored areas; but also for everyone translucent materials such as translucent veneers, porcelain, Stone disks, plastics, textiles and fabrics.

in the Interaction of the different possibilities in EL lamp training, the EL light colors, the illuminated materials and the glass block cover with different structures, ornaments and colors, can be varied and achieve customizable effects.

The EL lights with all modifications for creative lighting design can be built into the glass blocks. For this, a luminaire support plate made of a stable and slightly elastic material (e.g. polycarbonate, Acrylic glass, PVC, polystyrene) cut in the format of the internal dimensions of the glass block base body. This carrier plate can then be trained in different ways to the EL lamp. For pattern lights and small quantities prefabricated EL foil lamp laminates in standard dimensions are used. This standardized EL foil laminates are finished EL lights that come with simple tools, such as with scissors, cut to the desired format can be. For larger quantities EL foil lights are tailored in terms of dimensions, layout and Light color produced. In both cases, the EL foil lights on the carrier plate be glued. For large ones Quantities there is the technical possibility the carrier plate directly, or even the glass block cover, with EL pigments print.

Should If the light is emitted on both sides, the carrier plate must be glued at the front and back with EL foil lights, or it is done an additional back Printing with EL pigments. Of course, a second can also be used Carrier plate glued or printed on one side can be used.

This EL light panels are preferably fixed in half the depth of the glass block base body. In this position there are preferably knobs or in the wall of the base body other small overhangs into which the EL light panels clip and let it fix. Such fixation devices are not present, must glued the EL light panels, or at least on two sides with Spacers, preferably made of transparent material, are provided, the EL light panel when the cover is attached in the glass block base fixed. The electrical contacting and possibly electronic control can with the EL foil lights on the lamp itself, or on one meant for Contact extension, a so-called flag. In both cases the cables or contact tabs are guided through an opening in the wall of the base body and subsequently laid in the supply channels previously described.

The EL glass block lights can in a wall made of glass blocks individually, scattered, in rows, in subareas or as a full area Illuminated wall can be installed. It should be borne in mind that a glass block with built-in EL light is no longer translucent. EL glass block lights can therefore not used when transparency and translucency required are.

The Requirements for transparency and translucency can be met with a variant of the EL glass block luminaire will be realized.

To the EL glass block luminaire is designed as an EL light strip. The strip width is chosen so that the EL light strip is laid in the so-called supply channel the light can be guided through the translucent plastic body, then from the inner walls of the glass block is reflected and thus becomes visible.

The Structure of the EL glass block strip light corresponds approximately to that Structure of the EL glass block luminaire; also the possibility one-sided and two-sided light emission. However, one will the thickness of the carrier plate preferably choose that the EL light strip is well fixed in the so-called supply channel and the luminous surface (s), because of the better light output, as close as possible to the body comes to lie. The length coupling the EL glass block strip lights are preferably made using gapless plug connections. This way you can use any long and continuous EL light strips are produced.

There the EL glass block strip lights are only installed in the so-called supply channels the glass blocks themselves remain transparent and translucent. Indeed the appearance of this lighting is different and less pronounced than that the EL glass block light.

A more intense The so-called LED glass block strip lights are an alternative to the EL glass block strip lights.

LEDs are also modern lamps that are characterized by brightness, Longevity, robustness and very low energy consumption are the hallmarks. They develop little heat and are available in many light colors. When working closely together Standing RGB LEDs and electronic control can all Light colors, including Color changes, generated. It can be along the entire length or operate different modes in sections, e.g. Dimming, blinking and chaser effects.

Around Manufacturing LED strips of light becomes a strip-shaped board equipped with LEDs and / or SMDs in a row and close to each other. LEDs with their focusing lens heads have a smaller light beam angle and are preferred used when visible light points are desired. SMDs against it have a wide beam angle and are suitable when working together with light-diffusing covers, to generate a homogeneous, uniformly radiating light.

The LED / SMD light strips are preferably in square, transparent or translucent rectangular tubes or in profiles with a u-shaped cross-section adjusted and preferably waterproof with plastics or resins shed. Because the cross-section of the so-called supply channels at the front like on the back Usually twice as wide as it can be in a supply channel also two LED glass block strip lights set side by side become. Then you have the choice direct the light radiation in two rows in one direction, or one LED glass block strip light can go up, the other point downwards. The same applies to vertical laying for the left and right.

The length coupling The LED glass block strip lights are preferably made with non-spacing Plug connection.
