The principal characteristics of Daylight is that it changes with the time of day and year; even surrounding objects, pollution and position of the house will affect how daylight can be utilized as a part of design. Daylight has two components: Sunlight and Skylight. Sunlight is the direct beam of light from the Sun. Skylight […]
‘Incandescent’ means emitting light as a result of being heated, which is how this type of lamp works. Electric current is passed through the wire, which heats up and emits light. The length and diameter of the wire determines the amount of electricity needed to heat the wire and thereby the output intensity of light. […]
What is Photometrics? No it is not about clicking photographs nor has it anything to do with your awesome photogenic face, neither it is the number of selfies you can click in a minute. It is a far more serious thing. It is the science of measuring light. O’course you cannot measure light with the […]
Auxiliary equipments are of two types, Ballasts and Transformers. Both consume a little amount of power, adding to the total wattage of the Light Source. Transformers Transformers are used in low-voltage light sources. These low-voltage lamps work on current between 6 to 24 V (12V being the most common). However a building generally receives anything […]
Light sources that have built in optical systems are called Directional Sources or Reflector lamps. Ar, MR, PAR and R lamps are a few examples. Light sources which lack such in-built systems require external devices to modify the direction of light in order to make them useful for architectural applications. These modifications serve two purposes. […]
Principles of Electricity Electrons, which orbit around the nucleus of an atom, are electrically charged particles. These can be made to move from one place to another. This flow of electricity from one place to another is called electric current; and the rate of such flow is measured in amperes (amps, A). The potential amount […]
The light distribution and electricity circuits to the lamp/light source embedded within it. They also provide support to the lamp. The luminarie directs light to where it is needed in terms of distribution and shields the light source from causing glares. Luminaries thus are composed of many parts, each part carrying out a specific function. […]
Lighting design is the process via which lighting is made an integral part of the building’s architecture. Good lighting design is integrated both into the architectural concept of the building and its structure. Lighting should be integrated into the architectural concept in three ways: 1. It should enhance the original design, 2. It should ensure […]
