The widespread use of lighting began with the invention of the first practical incandescent lamp by Thomas Edison and Joseph Swan in the 19th century. Since then there have been significant improvements in lamp efficiency as well as the different types of lamp. As time passed, and new energy sources were developed, Lot new kinds of lamps were invented.
Lighting is essential to our daily activities. It is particularly important in the work environment. As it follows for efficacy and safety, electric lighting is needed in areas where natural light cannot reach.
Nowadays, there are many different types of lamps around the world, and they were all designed with a certain use in mind. Now, here are the different types of lamp used in our daily activities:
- Incandescent light lamp – is an electric light with a wire filament heated to such a high temperature that it glows with visible light. It is a kind of lamp is easy to install but expensive to run. The incandescent lamp produces a steady warm, light that is good for most household application. A standard incandescent bulb can last for 700-1000 hours and can be used with a dimmer.
- High-Intensity Discharge (HID lamp) – is a type of electrical gas-discharge lamp which produces by light means of an electric arc. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed fluorescent and incandescent lamps. Most of the modern vehicles use HID for their lighting bulbs.
- Fluorescent Lamp – these lamp or bulb work by passing a current through a tube filled with argon gas and mercury. It converts electrical energy into useful light much more efficiently than incandescent lamps. However, many fluorescent lamps classified as hazardous waste because it contains mercury. The United States Environmental Protection Agency recommends that fluorescent lamps be segregated from a general waste for recycling or safe disposal.
- Halogen Lamp- also known as a tungsten halogen is an incandescent lamp that has the small amount of a halogen such as iodine or bromine added. Halogen creates a whiter and brighter light as compared to incandescent bulbs as burns hotter.
Because of this, it can be operated at a higher temperature than a standard gas-filled lamp of similar power and operating life, producing light of higher luminous efficacy and color temperature. It also commonly used as the light sources in automobile headlamps.
- LED (Light Emitting Diodes) Lamps – LED lamps have a lifespan and electrical efficiency which are several times greater than incandescent lamps, and are significantly more efficient than most fluorescent lamps. It is the most popular and usable types of lamps in many households. It can be also used for the production of vegetables and ornamental plants.
LED lamps have achieved market dominance in applications where high efficiency is important at low power levels. Some of these applications include flashlights, solar-powered garden or walkway lights, and bicycle lights.
Advancement in the technology of lamps is ongoing, and today, we produce many kinds of lamps with various materials, power sources, and color of lights and for different usage.
