The document discusses an active learning assignment on illumination schemes for domestic, industrial, and commercial premises, emphasizing the importance of proper lighting in enhancing productivity and safety. It covers key terms in illumination, design considerations for indoor lighting, and specific requirements for domestic and industrial lighting systems. The text outlines the necessity of adequate illumination, uniform light distribution, and planning for different load requirements in electrical installations.

- 3. Introduction Light is the prime factor in the human life as all the activity of the human being ultimately depend upon the light. Where there is no natural light, use no artificial light is made. Apart from its aesthetic and decorative aspects, good lightning has a strictly utilitarian value in increasing production, reducing worker’s fatigue, protecting there health, and nervous system, and reducing accidents. The science of illumination engineering therefore, becoming of major importance.
- 4. Illumination Illumination is the deliberate use of the light to achieve a practical or aesthetic effect. Lightning includes the use of both artificial light Source like a lamp and light fixtures, as well as natural illumination by Capturing daylight.
- 5. Basic term of Illumination Luminous Flux :- It is defined as the total quantity of light energy emitted per second from a luminous body. It is measured in lumens. Luminous Intensity :- Luminous intensity is the light flux of a lamp or light bulb emitted in a specific direction. Illumination(E) :- Illumination is divided by the light flux of a lamp into lumen, where one lux is as illumination of one lumen per square metre.
- 6. Design of Indoor lighting Scheme Adequate illumination. Uniform light distribution all over the working place. Light of suitable colour. Minimum hard shadow and glare.
- 7. Illumination for Domestic Premises Proper light can enhance task performance, improve the apperence of an area, or have positive psychological effects on the occupants. Domestic loads are mainly consists of houses, residential buildings etc. The energy meter in case of the residential installation is single phase. The procedure carrying out in the electrification of residential buildings is similar to the electrification of the commercial buildings, only the load capacity is different.
- 8. Power distribution scheme of House Wiring
- 9. Design Consideration Of Electrical Installation System for Domestic Buildings :- Proper planning of electrical installation is very must. Before going for electrical installation of domestic building, concern person should have complete idea of load. Since each of the domestic buildings has different load requirement, different illumination scheme should be adopted.
- 10. Load calculation for service connection :- 1. Bulb point : 60W 2. Fluorescent tube : 60W 3. Ceiling fan : 60W 4. Exhaust fan : 100W 5. Socket outlet(5A) : 100W 6. Socket outlet(15A) : 1000W Total load on one phase in amperes = total watt on that phase / 230 Acc. To this load, the size of incoming cable should be taken
- 11. Illumination for industrial premises :- Factory lighting should provide adequate illumination on the working plane and give a good distribution of light, employ simple and easily cleaned and fittings and avoid glare. It is essential not only to avoid a glare from the lamp itself but reflect glare from any polished surface, which may be within the line of vision
- 12. Local Lighting :- On some points, fairly intense illumination is required. For this purpose, local lighting can be provided by means of adjustable fitting attached to the machine. Such lamp should be mountain in deep reflector so that glare is avoided. Local lighting should never alone, good general lighting is essential so that the dark places between the local lighting units are avoided. Dark place between local lighting units cause fatigue to the eyes, on account on its continually having to adjust itself to new conditions.
- 13. Emergency Lighting :- Some lights such as for : 1. Internal pilot lighting required for safe and speedy evacuation of personnel after main lighting circuit is off. 2. External pilot lighting, provide with a careful shades leading to shelter require for evacuation personnel. 3. For control posts, firstaid centres, etc.
