Investigate the design of Lighting Systems, Electrical Energy Essay

Investigate the picture of Lighting Systems, Electrical Energy Management and Tariffs - Essay ExampleThis is done when the consumption is less and halal and no wastage of energy is in that location. The lamps and other devices should be of proper rating and proper standard. The design should be such that required illumination is obtained in a least possible cost.a) Fluorescent Lamp - The basic construction of this quality of lamp is that it has a discharge tube made up of glass. in that location ar two electrodes at two the ends. This tube contains gases at certain pressure which on ionization emits blithe. The fluorescent powder is coated at both inside and outside the tube. The electrodes at both the ends are coated with any(prenominal) electron emitting material. A choke coil is attached in series with the lamp to stabilize current. One capacitor is also connected to compensate the power factor. This lamp emits white colour and widely used in homes, offices and shops.b) Electric Discharge Lamp - These were the starting type of lamps that were used. In these type of lamps there is a discharge tube in which two electrodes are connected to both ends and excited by electric source. The gas inside the tube gets ionized and emits light. There are various(a) types of electric discharge lamps namely sodium vapour lamp and mercury vapour lamp.c) filament Lamp - In this lamp a bewitching filament is connected to the electrodes and excited which emits light. The construction of these kinds of lamps is very simple. Earlier fine carbon was used as element in these lamps later on tungsten was preferred in place of carbon.Principle of good lighting While designing lighting system following considerations should be done.1) Proper illumination level - This is the major factor because for proper vision the brightness of the purpose should be proper which depends on illumination level. Degree of illumination depends upon some factors like size of the object, di stance from the observer, object background contrast. There are some standards made by ISI for illumination level in various parts of he building. For street lighting also some standards are made. Table below shows some average value of illumination level.PlacesIllumination levelHeavy Traffic routes30 Average duty routes15Secondary roads with local calling 8Secondary roads with light traffic 42) Uniform Illusion - The vision of eye depends on the brightness of the object. If the uniformity of light is there the eye has to adjust more. This will cause fatigue. The method to achieve uniform illumination Generalized light should also be employed with local light.3) Colour of light - The brightness of any object basically depends on colour of light falling on it. The composition of light should
