They are cheap and can be bought for low prices. There are different shapes of bulbs, but basically, all are rounded in shape. There are mainly three materials used for producing the filament of incandescent lamps, and these are carbon, tantalum, and tungsten. 9. Though the initial costs are less, over the period, the current bills are going to be high since filament bulbs draw large units of power. The filament bulbs emit out too much heat that would eventually lead to the rise in the temperature of the planet. Light sources • Incandescent lamp • Discharge lamp – Florescent lamp – Sodium lamp – High pressure mercury vapour lamp 3. Therefore, HID lamps provide substantially higher road illumination while consuming the same amount of electrical power and, in most cases, should last the life of the automobile. The incandescent lamp is the oldest type of electric lamp still in general use. A gas discharge lamp is a light source that generates light by creating an electrical discharge through an ionized gas. Change ), You are commenting using your Twitter account. In regions wherein people don’t use modern techniques of lighting, filament bulbs can be easily available and replaceable since they are largely circulated. The arc in an HID source is shorter, yet it generates much more light, heat, and pressure within the arc tube. High-intensity discharge (HID) lamps are similar to fluorescents in that an arc is generated between two electrodes. •    Energy saving is one of the most important concerns the world is facing. Its practical form was invented simultaneously in 1879 by Sir Joseph Swan in England, and by Thomas Edison in America. Deuterium Lamp & Xenon Lamp: Characteristics in brief.
