Introduction Electroluminescent (EL) sheets are lighting panels with some remarkable qualities: The foil is just 0.8 mm thick and emits light when connected to an electric current. Available in a variety of colours and shapes, the homogeneous EL lighting has become a serious alternative to conventional illuminants—especially in areas where custom designs with a minimal thickness (< 1 mm) or power consumption (1W/100 cm²) are needed and unwanted glares or shadows must be avoided. EL film is an active light source that shares the same characteristics as indirect light reflected from a matte surface. The light seems to come out of nowhere, it appears ethereal and mysterious. It does not glare and is easy on the eyes. Electroluminescence produces very short light waves, which are perfectly perceptible to the human eye. A three-dimensional light effect can be achieved by bending the film. It can also be attached to the surface of any object to make it glow. An EL film is a so-called Lambertian radiator: Unlike with neon lamps, filament lamps or LEDs, the brightness of the surface appears the same from all angles of view; electroluminescent light is not directional and therefore hard to compare with (thermal) light sources measured in lumens or lux. The light emitted from the surface is perfectly homogeneous and is well-perceived by the eye. EL film produces single-frequency (monochromatic) light that has a very narrow bandwidth, is absolutely uniform and visible from a great distance. - EL film generates very short light waves, which are perfectly perceptible to the human eye.
Calculate the area you wish to illuminate and order the adequate size of EL sheets. Install the sheets and connect them to one of our supply units. Connect this unit to a power source and you’re done. Lifespan EL crystals in the pigment layer emit light starting at 20 VAC, which is the minimum voltage required to achieve an electric field strength that excites the electrons sufficiently. The luminance, or brightness, depends on the amplitude of the input voltage. Increasing the input frequency results in a colour shift towards a shorter wave length, which appears brighter to the eye. Both amplitude and frequency should be adjusted carefully to the operating instructions for the EL film and the specific application, as a higher operating voltage and/or frequency will generally result in a shorter lifespan. The lifespan of an EL film depends on the strength of the electric field, the on/off interval, and the exposure to UV light. It can be increased with a blinking or stacking sequence. In optimum conditions and with a voltage of 110 VAC and a frequency of 400 Hz, an electroluminescent film can achieve a lifespan of 15,000 hours. |

EL-Leuchtfolie Unsere EL-Leuchtfolie, auch bekannt unter den Namen EL-Folie, Leuchtfolie, Lichtfolie, Elektrolumineszenz, Folienlampe oder Leuchtstreifen, basieren auf dem Prinzip der Elektrolumineszenz. Bei dieser Lichttechnologie (Elektrolumineszenz-Leuchtfolie) gibt es kein „Abstrahlen“ von einem Lichtort oder Lichtherd wie bei Neonleuchten, Glühleuchten oder LED.
EL-Folie Leuchtfolie, EL-Leuchtfolie, Elektrolumineszenz, Leuchtstreifen, EL-Folie, Leuchtfolien, Lichtfolie, Lichtfolien, Lichttechnik
Die Leuchtfolie ist ein sogenannter Lambert-Strahler, d. h. die Leuchtdichte der von der Oberfläche ausgehenden Strahlung ist von jeder Seite betrachtet gleich.
Elektrolumineszenz Leuchtfolien sind aktive Lichtquellen mit den Eigenschaften eines indirekten Lichts, gleichbedeutend mit der Reflexion von Lichtstrahlen an einem matten Körper. Das Licht der EL-Folien scheint aus dem Nichts zu kommen und wirkt unrealistisch und unerklärlich. Es erscheint angenehm und blendet nicht.
