Download file to see previous pages In this type of lamp, there is glass tube which is filled with a mixture of mercury vapour at low pressure and argon. The inner side of the tube has a phosphorous coating which is used to illuminate the light.
As current flows through the electrodes in the tube, it goes through the gas which is contained between. Consequently, there is emission of ultraviolet light from the mercury arc which is converted to visible light by the fluorescent coating found on the inside of the tube.
To facilitate proper lighting in this scenario, a high mercury pressure lamp is necessary to facilitate this lighting system. This is due to the fact that this type of lamp produces less heat and uses less energy and thus it conserves energy while at the same time producing enough lighting.
In the design of this type of lamp, an outer glass envelop is filled with nitrogen gas which acts as a coolant that keeps the arc tube at correct temperatures. This type of lamp contains a quartz discharge tube which is filled with argon gas and small amount of mercury which is in liquid form. Two electrodes are located at the ends of the tube which begins the discharge. A 10 – 30 Ω resistor is connected in series with the secondary electrode.
On switching on the light, at first there is no current flow. Then the power supply voltage appears across the main electrode and between one of the mains electrodes and the secondary electrode through the series resistor (B & B training Associates Limited). Consequently, there is production of an arc between the secondary and the main electrode resulting in occurrence of ionisation. The pressure and the heat build-up resulting in the formation of more high pressure and vaporised and high pressure arc between the electrodes.
It is made of a sintered aluminium oxide tube that is being supported by two rods. The inside of the glass is coated with white material that facilitates spreading of the light. There is a combination of sodium and ...Download file to see next pagesRead More

... power; however, the creation of the same drastically altered the geography of the land including significant changes and alterations to the biodiversity of the neighbouring areas. The Kariba Lake was located in the tropics and was one of the first projects to be built in the region. It was created by damming of the Zambezi River which flowed between the two countries i.e. Zambia and Zimbabwe in the year 1959. The building of this lake was referred to as an audacious engineering feat since it was created by clearing up a large proportion of the lands leading to displacement of thousands of locals (Gray, 2000:69). Major problems encountered The construction of the Kariba dam brought about significant changes in the area, especially... ...

Utilisation of Electrical Energy

...?Utilisation of Electrical Energy Utilisation of Electrical Energy Introduction Artificial lighting is currently used all over the world and its use is predominantly non-homogenous. The most commonly source of power used in powering artificial lighting is the electric power, though, in some under – developed countries, there is a widespread use of fuel based lighting. The average consumption of electric energy around the world is approximately 19 % of the total electric energy produced. This calls for the specialized improvement in the lighting efficiency to save energy which translates to conservation of the environment. Different environment requires different lighting luminaries. The choice of a...

...How to Improve the Status of an Engineer in Society By Devangini Chauhan Engineering is the application of scientific and technical knowledge to solve human problems where Engineers use their imagination, judgment and reasoning to apply science, technology, mathematics, and practical experience. The design, production, and operation of useful objects or processes are the final outcomes of this process. Apart from being a subject that ranges from large collaborations to small individual projects, almost all engineering projects are beholden to some sort of financing agency: a company, a set of investors, or a government. This finds outcome in the fact that large-scale...

...relative to automobile development. Germany became the source of automobile technology back in the 1870s when the first four-stroke internal combustion engine was created by Nicolaus Otto (Cross & Szostak, 2004). What followed were progressive improvements to this engine and automobiles in general. The process finally ushered in the electric ignition that saw the emergence of a revolutionized transport sector. Automobiles for private and public use emerged, allowing people to move from one place to another with ease. Automobile development changed the social face of the world. What essentially began as a simple invention in Germany quickly spread all over the world, changing the manner in which transport...

.... The solutions for device scaling involve development of conventional MOSFETs on substrate of silicon-on-insulator. The insulator creation involves oxygen ion implantation and layer annealing for oxide formation. Ultrathin SOI MOSFET is involved in the efficient reduction of SCE (Short Channel Effect) and leakage paths elimination thus good for device scaling. Faster movement of carriers enhances the performance of device and can be done through strain engineering and orientation effects. Finally, there is the target of production of sub-10-nm gate-length MOSFETs of 5 A oxide thickness and junction length under 10nm by 2016 (Ieong et al 2004). Pan, D. Z., Yang, J. S., Yuan, K., Cho, M., & Ban, Y. (2009, October). Layout...
