How To Connect Light Inside Your Home,Office

The simplest schemes for lighting are:-

1- Direct lighting

2- Semi direct lighting

3- Semi-indirect lighting

4-Indirect lighting

5- General lighting

1- Direct Lighting:-

widely used lighting system,in this system more than 90% of the total light fulx is amde to fall directly on the working plane with the help of deep reflectors.

its is mainly used in general outdoor and industrial lighting.

throught out the most efficient but causes a hard shadow and glare appear during lighting.

2-semi dierct lighting:-  

In This lighting scheme 60 to 90% of the total light flux is made to fall downward directly with the help of semi direct reflectors.

reaming light is used to illuminate the ceiling and walls. such a lighting scheme is best suited to room with high ceiling where a high level of uniformly distributed illumination is desirable.

the Glare in such units is avoiding by employing diffusing globe which not only improve thew brightness toward the eye level but also improve the efficiency of the system with reference to working plane.

3-Semi-indirect lighting:-

In this lighting scheme 60 to 90% of total flux is thrown upwards to the ceiling for diffuse reflection and the rest reaches the working plane .

direct excepts for some absorption by the bowl .This lighting scheme is with soft shadows

and glare free.

it is mainly used for indoor light decoration purpose.

4-Indirect lighting:-

In this lighting scheme more than 90% of total light flux is thrown upwards to the ceiling for diffusion reflection by using inverted or browl reflectors.

in such a system the ceiling acts as the light source, and the glare is reduced minimum.

5-General lighting:-

In this scheme laps made of diffusing glass are used which give nearly equal illumination in all directions
