Incandescent Lamps

An incandescent lamp is a popular type of electric lighting. It is an electrical device composed of a filament of wire, usually made of tungsten, that is contained within a transparent, insulated glass bulb. An electric current passes through the heated filament, which prevents oxidation and creates light. Incandescent light bulbs are relatively simple and inexpensive to manufacture, but have several disadvantages. They require fairly high electricity, and their lifespan is very short compared to other types of lighting. Incandescent bulbs are, however, still the most widely used type of lighting due to their affordability and availability.

Neon Lamps

A neon lamp is a light source that uses a gas filled tube to create a glow, a form of cold cathode lighting. The tube is typically filled with a blend of noble gases, such as neon and argon, and is equipped with electrodes at either end. When an electrical current is applied between the electrodes, it excites the gas molecules, and the resulting impact of electrons and ions in the tube produces a bright light. Neon lamps are used mainly in signage, and have been increasingly used for decorative accents in homes and businesses. They have several advantages over incandescent lamps, such as lower energy consumption and longer life-span.

Application Field

Incandescent lighting is used in most residential, commercial, and industrial spaces. It is widely used in retail environments, restaurants, hotels, and shopping centers. Incandescent lamps can also be found in garages and roadside stands.

Neon lighting is most commonly used in signage, but is also used for decorative accenting indoors. It is often found in night clubs and pubs, as well as retail, industrial, and informal spaces.

Working Principle

An incandescent lamp works by electrically heating a wire filament contained inside a glass bulb. As the wire filament is heated, it emits a bright light. The heat of the filament also helps to prevent oxidation of the wire.

A neon lamp works by passing an electric current between two electrodes inside a glass tube filled with a noble gas. As the current passes through the gas, it excites the gas molecules, and this creates a bright glow.
