CONSTRUCTION OF TWO FEET ELECTRONICS FLUORESCENT LAMP. Fluorescent tubes are typically found in domestic and commercial environments such as kitchens, garages, schools and offices, preferred for their versatile applications and functional design. Compact fluorescent lamp use vacuum pipe similar to classic strip lamp and princip of energy transformation to light is same. Due to the importance of lighting, I am introducing a two feet electronic fluorescent lamp, which shall be able to supply light energy at any particular time of the day or night as the need may be. Electronic ballasts contain a small circuit board with rectifiers, a filter . The ultraviolet light then excites a phosphor coating on the inside of the tube. Fluorescent lamps are made of a glass tube filled with a low pressure mixture of gases, specifically mercury and noble gases like argon, neon, xenon and krypton. The electrode mount assembly is almost similar to the stem press unit in the incandescent lamps. Engineering being the mother every technology cannot be neglected. In normal p-n junction diodes, silicon is most widely used because it is less sensitive to the temperature. Argon can also be used in gas-discharge lamps to emit violet light, or blue if mixed with mercury. preheat fluorescents. To be able to design circuit diagram 1.3 THE SCOPE OF THE PROJECT and (10) cleaning and cleaning . The construction of LED is similar to the normal p-n junction diode except that gallium, phosphorus and arsenic materials are used for construction instead of silicon or germanium materials. Fluorescent lamp Bulbs Construction and working : Atypical CFL consists of a gas filled gas tube with two electrodes mounted in an end cap. A fluorescent lamp construction is described utilizing a particular combination of two different phosphor materials in order to produce an efficient composite emission. A fluorescent lamp basically consists of a long glass gas discharge tube. The incrative nature of engineering depends on the technical know-how of the engineer. FLUORESCENT LAMP • a form of electric discharge light source. The fluorescent lamps consist of a glass. In some cases, germanium is used . Remove the old starter the same way you removed the old tube, by twisting it out of its socket in the fixture. The fact that our present electric power supply has been characterized by constant low power output, the two feet electronic fluorescent lamp found its greater advantage in many place such as . 2.2.2 Compact fluorescent lamps (CFL) 2.2.3 High intensity discharge lamps (HID) 2.2.4 Xenon Arc Lamps; 2.3 Light-emitting diodes LED; 3 Related articles on Designing Buildings Introduction .

Total set up of a lamp requires two bases and choke coil with a starter. 1 (b)) generally consists of a long glass tube (G) with an electrode at each end (E 1 and E 2 ). Mechanical construction Lamp is usually compounded of two parts. Compared to general service incandescent lamps giving the same amount of visible light, CFLs use A chemical element, and one of the noble gases. Video of TFEL construction: How TFEL works: TFEL has a phosphor layer that emits light when a big enough electrical field is applied. The new regulations would phase out most remaining halogen lamps from September 2021 and the traditional fluorescent tube lighting, which are common in offices, from September 2023 onwards. The process that occurs inside a fluorescent light involves molecules of mercury gas being heated by electricity and made more conductive. Fluorescent lamps are lamps in which light is produced as a result of flow of free electrons and ions inside a gas. (RK) Primer of SCHOOL LIGHTING LAMPS AND MAINTENANCE. 0. We also . Find rechargeable work lights you can carry and use anywhere, such as the rechargeable LED work light with a battery that lasts 1.5 hours, or the Luceco rechargeable LED work light IP65 that runs for 3 hours. Standard fluorescent lights are available in tubes (generally 48 to 84 inches in length). To be able to maintain repair and damaged fluorescent lamps. CONSTRUCTION OF TWO FEET ELECTRONICS FLUORESCENT LAMP ABSTRACT Engineering being the mother every technology cannot be neglected. Construction and Working of Fluorescent Lamp Fluorescent lamps are the tube lights we use at home and elsewhere. The process that occurs inside a fluorescent light involves molecules of mercury gas being heated by electricity and made more conductive. 2 is a graph depicting emission curves obtained with fluorescent lamps having the lamp construction described in FIG. THIS . It is filled with an inert gas typically argon which acts as conductor and also consists of mercury liquid. Traditionally, energy-saving lights save energy by making light without the heat using a completely different process called fluorescence.This is a trick similar to the one used by creatures like fireflies and glow-worms, whose bodies contain chemicals that make "cool light" without any heat. In circuit time, much of the indoor work done by human depended up day light of sun being available, which was created by God as the first thing. Decorative lighting that is part of a building's design and construction. ABSTRACT. CFL is an acronym that stands for compact fluorescent light.
