The electric lamp, invented in the 19th century, has now become one of the fundamental necessities for lighting spaces. It is a key element of devices designed to convert electrical energy into light. Due to advancements in science and technology, there are now various types and sorts of lamps available. In this article, we will share information about some of the most commonly used lamp types and their characteristics.
Incandescent lamps: are widely spread and cheaper compared to other lamp types. They work by passing an electric current through a filament (tungsten, melting at 3000 degrees Celsius) which generates heat. During incandescence, the filament emits light, glowing like red-hot iron. The higher the filament's temperature, the brighter the light. Incandescent lamps emit heat into their surroundings during illumination. Their luminous efficacy is 15 lumens per watt.
Halogen lamps: are a type of incandescent lamp. Unlike traditional incandescent lamps, they contain halogen gas inside. They emit white light and are more durable. Their luminous efficacy is 25 lumens per watt.
Fluorescent lamps: emit a flat, predominantly cool, bluish light. They do not glare, do not emit heat when in operation, and are long-lasting. Their luminous efficacy is 45-100 lumens per watt.
LED lamps: are new generation lamps. They are also called light-emitting diodes. They are solid-state semiconductor devices that emit energy in the form of photons and convert electricity directly into light. They save energy. They are long-lasting. They come in various designs. They provide a vibrant appearance in lighting fixtures.
May you live in well-lit homes!
