elektronical luminance

[salim ALTIN]

merhaba.
Arkadaşlar elektronical  luminance diye bişey var. back light olarak veya reklam panosu olarak kullanıyolar bu konuda bilgisi veya kullanmışlığı olan varmı.?  düşük voltaj , yüksek frekans çalışıyor (500 hz).Electro-luminescence

Definition - The Electro-Luminescent phenomenon is today's state of the art, "solid state" lamp technology, consisting essentially of millions of tiny phosphor particles which light up when an electrical energy is applied to them. When electrons are relaxed and return to their unexcited state, light is emitted. Electro-luminescent lamps draw very little power, therefore, produce little heat, and, because they don't contain filaments or mechanical parts, they are not susceptible to shock, vibration or catastrophic light failure. Unlike directional light sources such as LED's and incandescent, electro-luminescent lamps are lambertian. They have a uniformly illuminated surface, which appears equally bright from all viewpoints of 160° on a flat surface. Additionally, a 360-degree visibility is possible with a wrap-around configuration.

Merhaba.
gerçi benim de ingilizcem iyi değil sanırım pek çok arkadaş ta anlamaya bilir ama bu konuda fazla bilgi yok piyasada. ve ilginç bir konu. ingilizceyi hakkiyla türkçeleştirebilecek vakti olan bir arkadaşında ellerinden öperiz yani.

Colors - Available standard colors are White, Blue, Blue-Green, Green and Orange. Increasing the frequency will change the color slightly while increasing the light intensity, but this will also decrease the time to half-brightness. Increasing the voltage will increase the light intensity but decreases the time to half-brightness to a less degree than frequency does.

Size Limitations - Our EL lamps can be printed in any configuration with a lit area up to 19 x 23", but, if the design allows, lamps can be matrixed or married together for larger, longer pieces. Prototype sheets are 5 x 8" and can be cut to any size or shape for a quick and easy evaluation of how your product will look with EL backlighting.

Turning on the Power - EL inverters convert the DC input current to the required AC necessary current to operate the lamp. The inverter is critical to the overall performance of the lamp's durability, power consumption, size and weight and, of course, the cost of the completed system. Operating EL lamps at brighter illumination may shorten the lamp life. If your design would lend itself to a flashing light, it would assist in reducing power consumption, enhance and spotlight the visual effect, and extend the battery life, but this might add cost and size to the inverter.

Technical Benefits of GSI EL lamps - We produce some of the brightest EL lamps available - typical green ~100 cd/m2 (29 fL) and our new white-on/white-off has ~35 cd/m2 (10 fL).
BKL Inc., a Graphic Solutions International LLC Company, is a recognized leader in the production, testing and qualification of EL lamps and their associated driver systems. Our retained BKL staff has over 74 years of combined design implementation experience and a proven track record of providing high volume and high quality EL lamps for leading manufacturers of consumer electronic products. Some of those products include cell phones, pagers, hand-held wireless devices, PDA's, remote controls, night-lights and other popular consumer products.

Advantages of EL over conventional light sources:

Variety of Shapes and Sizes

Thin - typically less than .5mm thick (.25-.5mm or .01-.02 in.) allowing downsizing of end products

Flexibility  - can be bent to configure almost any shape and design

Strength - almost unbreakable

Reliability - lamps are almost impervious to shock vibration and since the lamp effectively consists of millions of microscopic lamps, there is no catastrophic failure, leaving you in darkness

Low Power Consumption - consumes 75-90% less power than a point light source such as an LED

High Efficiency and Brightness - typically 80% of energy is converted to light

Low Operating Temperature - generates negligible heat

Uniform Lighting

Long-life

No Glare

Bir ara elimde arizali 5cm x15cm ekranboyutlarinda LCD ler vardi. Hepsinde de backlight isiklandirma vardi. Birisinin yuksek voltaj devresi de takiliydi.

Isiklandirmanin nasil oldugunu merak edip birisini soktum. Karsima plastik kimlik kartlarimiz benzeri esneyebilen ici yesil renkte yarim mm kalinliginda plastik bir nesne cikti. Iki tanede ucu vardi.

YV devresine 5V verince isil isil parliyordu.

Makasla plastik kabi kenardan kestim. Aynen kimlik kaplama mantigi ile yapilmis. Iceriden incecik bir yesil nesne cikti. Yesil boyayi kazidigimda altinadan aluminyum levha cikti. Elektrodlardan birisi bu levhaydi. Diger elektrotda yesil nesnenin en dis kenarini cepe cevre dolasmis yaklasik 1mm kalinliginda metal kaplamaydi.

Daha sonra bu malzemenin makasla istenilen sekilde kesilip ust elektrodu olustulup plastik kaplama  yapilip kullanilacagini bir sitede okumustum. Yanlis hatirlamiyorsam vakum ortaminda PVC kaplaniyor.

merhaba.
neon lambaların yerini alacak diyorlar bu iş. İlginç geldi banada. Çok farklı kullanım alanları olabilir. Elektronik ile olan bağlantısı nedeniyle bana bahsettiler yoksa benim de haberim yoktu. Bu işin tekniğini biraz incelemek lazım.

Bu link te anlatmışlar ama bunun türkçesi olsa da bu başlık altına koyabilsek keşke.

Burada lcd ile bir karşılaştırma da var.
