715 Optoelectronics

Incandescent lamps use electric current to heat a wire filament to a high temperature and thus produce light. The heat generates light through thermal radiation, which is energy emitted as light when an object is heated to a high temperature. The filament is usually made from tungsten, which is an element in Group 6 on the periodic table and has a high melting point. This is because the filament has to get extremely hot in order to produce a large amount of light, and tungsten is good at withstanding the heat without melting or evaporating. Incandescent lamps are considered one of the simplest of all types of lamps and can be found in just about every home and business. Incandescent lamps are available in different shapes and sizes, from candle bulbs to large “globe” bulbs, and different wattages, allowing for a variety of applications.

Neon lamps are a type of gas-filled discharge lamps. They are used where a colored light is needed, where the colored shades help to provide an effect associated with the area. The most common gas used in this type of lamp is usually neon, hence the name. Neon lamps work by passing electricity through a gas filled glass tube. When an electrical current passes through the tube, atoms in the gas become energized, which in turn excites the electrons and causes them to jump from one energy level to another. This transition causes electrons to glow and emit a variety of colored light. Neon lamps are most often used for decorative lighting.

715 application field and working principle is referring to both incandescent and neon lamps. The application fields of both incandescent and neon lamps are many and varied and these two types of lamps can be used in both commercial and residential applications. The working principle of incandescent lamps is that electricity is passed through a tungsten filament, which produces light through thermal radiation. The working principle of neon lamps is that electricity is sent through a gas filled glass tube, which causes electrons to glow and emit a variety of colored light. Both incandescent and neon lamps are important components of many residential lighting systems.
