Light\nemission of low temperature also known as luminescence, has always existed.\nLuminescence comes in all kinds of forms, fireflies, or the red tide where the\nbeach sand lights up from enchanting bacterial life form. Imagine having this\nluminescence to be in a controllable environment for our use. The discovery of\nsuch technology, \u201cEL\u201d phosphor was built on the foundation in 1936 by George\nDestriau<\/strong> who believed that zinc sulphide compound emitted\nlight in an electric field. Years of research in the \u201940s and 50\u2019s carried out\non various phosphors that would illuminate radar screens lead to modern-day\ntelevisions including LCD Displays.<\/p>\n\n\n\n

The world of EL Technology is growing at a fast pace, as the utilization is increasing with advancing technology and new products. Today EL manufacturing is done in China, Taiwan, and Singapore on large basis. It is getting more commonly used in the products sold as a current trend, products such as EL Night Lights, animated signs, EL Panels used as backlight in\u00a0membrane switch keypads<\/a> etc.<\/p>\n\n\n\n

What is an Electroluminescent Lamp?<\/strong><\/p>\n\n\n\n

According\nto Wikipedia \u201cElectroluminescence is an optical and electrical phenomenon in\nwhich a material emits light in response to an electric current passed through\nit, or to a strong electric field.\u201d Electroluminescence serves as the building\nblock for EL Lamps.<\/p>\n\n\n\n

An\nEL Lamp is a LEC (Light Emitting Capacitor). These LEC lamp\u2019s use phosphor as a\nkey element which emits light when it is energized with an alternating electric\nfield thus serving it\u2019 purpose.<\/p>\n\n\n\n

Electroluminescent Lamps are flat, thin along with cold illumination sources that can be refined into complex shapes. This allows them to be able to be placed into various products where space and\/or power are limited. These are commonly used with backlighting products. Few examples are LCDs, aircraft instrument panels,\u00a0capacitive membrane switch<\/a>, and advertising signage.<\/p>\n\n\n\n

Construction and Scope of EL Panels:<\/strong><\/p>\n\n\n\n

Electroluminescent\nlamps are constructed with high precision printed multiple layers of dielectric\nand insulated layer structure. Finishing touches are done with part-level\nremoval and followed by connector attachments. This light technology consists\nof a flat capacitor construction with zinc sulphide phosphor particles between\ntwo electrodes, one of which is transparent for light to escape. When AC\ncurrent is applied to the electrodes generating an electric field within the\nphosphor layer, causing change in the field and emitting the visible light.<\/p>\n\n\n\n

As\nthis technology is a paper-thin laminated panel they are easy to cut and have\nany shape. It consumes very little power and produces little heat making them\nideal for use. Moreover, it doesn\u2019t contain mechanical parts or filaments,\nmaking it unsusceptible to vibration, shock, or catastrophic failure of light.\nThese characteristics have increased the use of EL lamps into other products,\nbeing efficient and more productive than other alternatives. Other more\nnoticeable characteristics of EL lamps are:<\/p>\n\n\n\n
