Electro Luminescent Lamps And Their Benefits

An Electro Luminescent Lamp is a capacitor that releases light when AC current is transmitted to it. Electro luminescent Lamp is comprised of a chain of printed layers with a layer of phosphor that is enveloped between two conductive layers. Basically, it is equipment which needs electric power for charging and then it uses the acquired energy in transmission of light. These lamps are mostly used for backlighting in low light surroundings. It is commonly perceived that Electro Luminescent Lamps are more effective for backlighting of membrane switches when they are thin. Traditional TV sets used Electro Luminescent Lamps; they used to glow when they came in contact with electrons discharged from a cathode in the back of the tube.

Electroluminescent lamps are available in various colours such as yellow/green, blue/green, blue, white, orange, etc. The most popular colour among all others colours is green, as it provides the highest light output. The colour of the light is determined by the type of electro luminescent material used. Some common materials used are as follows:-

• Thin film zinc sulphide adulterated with manganese which emits an orange-red light.
• Powdered zinc sulphide mixed with copper which provides a green shade light.
• Powdered zinc sulphide adulterated with silver that imparts a bright blue colour.
• Natural blue diamond with a trace of boron.
• Some organic semi-conductors.

Benefits of using Electro Luminescent Lamps:-

• Efficiency - Electro Luminescent Lamps are highly efficient.
• Cost effective - These lamps use very low amount of electricity as compared to other lighting options. Hence, the expenses of power consumption are minimal.
• Environment friendly - these lamps do not contain mercury and do not affect the environment.
• Versatile - Electro Luminescent Lamps are quite versatile and can be used in various industrial applications.
• Not directional - Electro Luminescent Lamps are not directional when used as computer monitors. Unlike LCD’s they look good from all angles.
• Water proof - Electro Luminescent Lamps are water can be used for making water proof computer screens which are very durable and of lighter weight than LCD and plasma screens.
• Flexible - Electro Luminescent Lamps are very flexible and they can be moulded in narrow strings, flat panels and many other small shapes.

Electro Luminescent Lamps are aesthetic, cost effective, durable and efficient. They are better than other forms of lighting. They are used in many applications like night lights, illuminating watches, luminescent clothing, waterproof displays, computer monitors, medical tool display screens and many more.
