Lighting Techniques

Lighting enhances the ambiance of the place. It is the deliberate application to achieve some pleasing aesthetic effect. Lighting techniques differ from purpose to purpose. For example, for lighting up of the Dining Room, the kind of lighting technique and lighting fixtures used are different from that used in lighting up Water bodies such fountains, artificial lakes etc. because each one of these places creates a whole different feel of the space.

In this article, we will discuss Direct Lighting Techniques and the lighting fixtures that are used specifically for Direct Lighting System.

Here are some of the other lighting methods apart from Direct Lighting:

  1. Direct Lighting
  2. Semi-Direct Lighting
  3. Indirect Lighting
  4. Concealed Lighting
  5. Semi-concealed Lighting

Dining Lighting makes use of Concealed Lighting, Semi-concealed Lighting, Direct and Indirect Lighting System.

Task Lighting makes use of Direct Lighting system.

Underwater Lighting makes use of Diffused Lighting system.

Spot Lighting is complete different system of Lighting but since it has focussed illumination, it can fall under the category of Direct Lighting.

Semi-Direct Lighting Design

Semi-Direct Lighting is the kind of lighting provided from a source without reflection from other surfaces.

In daylighting, this means that the light has travelled on a straight path from the sun to the point of interest.

In electrical lighting it usually describes an installation of ceiling mounted or suspended luminaires with mostly downward light distribution characteristics.

Types of Lighting

One of the primary functions of a luminaire is to direct the light to where it is needed. The light distribution produced by luminaires is characterized by the Illuminating Engineering Society as follows:

  • Direct Lighting ( 90 to 100 percent of the light is directed downward for maximum use.
  • Indirect Lighting( 90 to 100 percent of the light is directed to the ceilings and upper walls and is reflected to all parts of a room.
  • Semi-Direct Lighting( 60 to 90 percent of the light is directed downward with the remainder directed upward.
  • Semi-indirect Lighting ( 60 to 90 percent of the light is directed upward with the remainder directed downward.
  • Highlighting Lighting( the beam projection distance and focusing ability characterize this luminaire)
