Lamps are devices used to produce electrical light. Generally, they consist of a sealed glass tube, containing an inert gas and filled with two electrodes. When an electric current passes through the gas, it becomes excited and emits ultraviolet radiation, which is then converted to visible light by a phosphor coating. There are two main types of lamps; incandescents and neons.

Incandescent Lamps

Incandescent lamps, or bulbs as they are often known, are widely used in domestic properties. The lamps are filled with argon and nitrogen gas, and the electrodes consist of a tungsten wire, enclosed in a glass bulb. When these bulbs are switched on, the tungsten wire is heated by the electric current travelling through it. This heating causes the wire to produce a bright light, which is then dispersed by the glass bulb. The light produced by incandescent lamps has a yellowish hue and it is often used to produce a warm, relaxing atmosphere.

Neon Lamps

Neon lamps are more powerful than incandescent lamps and they are often used in large-scale lighting installations. The lamps consist of a sealed glass tube, containing neon gas and two electrodes; an anode and a cathode. When the lamps are turned on, an electric current passes through the gas and causes it to become excited. This excitement produces a deep, intense light, which is often used to provide ambient lighting in public spaces such as nightclubs and bars. Neon lamps are also known for their vibrant colours, which can be used to create a vibrant atmosphere in otherwise dull environments.

2140 Application Field and Working Principle

The 2140 application field applies to both incandescent and neon lamps. It is a durable, rust-resistant material that has been designed to withstand the pressure of the light-emitting gases inside the lamps. The application field is also highly resistant to temperature fluctuations and can be used in high-pressure environments. The working principle of 2140 is quite simple. The material is heated by the electric current as it flows through the lamps. This heating causes the material to emit a bright light, which is then dispersed by the glass bulb. In the case of neon lamps, the material is excited by the electric current, producing a deep, intense light. In both cases, the application field helps to disperse the light in an even, uniform distribution, making it ideal for large-scale lighting installations.
