Digital Lighting and rendering

 




Digital Lighting and rendering, EL Light is one of the types of lighting whose applications have recently appeared and have many uses, whether in decoration and architecture or in technology such as screens, phones, control panels, emergency lighting, lighting units, watches, and fashion and Many more.

 

Digital Lighting and Rendering Electronic lighting is produced in the form of an illuminated wire (EL Wire) or a light panel (EL Panel) or other forms that we will get acquainted with this topic.

 

Electronic illumination (EL) technology: how does it work?

Electronic lighting is an electro-optical phenomenon of a material that emits light in response to the passage of an electric current. It was invented by Georges Destro in the Marie Curie laboratory in Paris in 1930 during their research on radium, but the technology development began in the mid-1990s.

 

Electronic illumination (EL) features

  • Very little heat emission compared to normal lighting.
  • High clarity and visibility in darkness, smoke, and fog.
  • Does not affect the eyes (low glare).
  • High elasticity and very thin thickness.
  • It does not affect night vision and is clear in long distances.
  • It does not require maintenance and does not contain any hazardous materials.
  • Low energy consumption, the most efficient light source ever.

 

Electronic illumination (EL) information

  • Electronic lighting illuminates when placed in the AC Volt range.
  • As the voltage or frequency increases, the intensity of illumination increases.
  • The color changes depending on the frequency.
  • The lighting loses its strength after its service life (about 15 thousand hours) and is not affected by the number of times of operation.
  • Uncoated phosphorus is fast perishable due to moisture.
  • The color of the lighting is chosen before the manufacturing stage.
  • Blue/green tends to have a longer life and stronger light.
  • The lifetime and intensity of light are affected by the type of phosphorous used.

 

Electronic illumination light measurement method

The luminance and radiation of electronic lighting are measured, like other types of lighting, by:

 

Luminance

It is used to measure the visibility of objects, such as exit signs, and the unit of measurement is (Foot-lambert) = 9.32 lamps / m2.

 

Radiation

It is used to measure the amount of emitted light, such as emergency lighting and indirect lighting, and it is measured by Lux.

 

Electronic lighting colors

 

Blue / green

Made of natural blue and green phosphorous, it gives the strongest illumination and the longest operating life. It is muffled white when it is sealed.

 

white

The dye is added to blue or green phosphorous to give a bright white color, which is pink and closed.

 

Other available colors: yellow, red, purple, green, blue, and orange. Made by adding a dye from green or blue and white to give the desired color.
