Green Electric Components | LED Lights | Research in lighting

Future of Lighting Industry

We are all acquainted with LED (light emitting diode). It is a semiconductor light source and was introduced as a practical electronic component in 1962. Earlier, LEDs emitted low-intensity red light but now the scenario has completely changed. We can now count LEDs under GREEN electronic component. They are tiny but efficient. Technology has made it possible in achieving efficiency with LED lighting.

LEDs pros and cons

Let us first look at it with a positive perspective.

LEDs are supposed to be the future of our lighting industry. They require low power for illumination. The power required for illumination is as low as required for a flashlight or the screen of our cellphone.

LEDs are very useful to light up smaller rooms. Bright white light can be achieved with minimum requirement of electric power. It has been used by the lighting designers. They can be very easily integrated with the false ceiling in any mall or showroom. Since, the requirement for the number of lights is larger in a showroom, LEDs are a very superior and an economical alternative since they are efficient and at the same time consume less electric power. I would say this is great way to embrace sustainability.

Now, let’s look at it with a perspective that will help us understand the shortcomings in LEDs technology. We will also discuss how researchers have found a perfect way to overcome these shortcomings.

Secondary lighting systems | Lighting Techniques

Lighting systems | Illumination Techniques

Lighting Systems comprises of two main systems:

  1. Primary Lighting Systems
  2. Secondary Lighting Systems

Both of these lighting systems are to be integrated together in designing the lighting for any space.

Earlier, we discussed “Primary Lighting Systems”. Now we will move on with the discussion on Secondary Lighting Systems.

Secondary Lighting Systems

1. Accent lighting- 15 times more than task lighting

2. Effect lighting- no functional value

3. Decorative lighting

4. Architectural lighting

5. Mood lighting

Underwater Lighting Techniques | Aqua Architecture

Under water lighting deals with the lighting systems placed inside water entities like swimming pools , fountains , etc , and some times even in smaller areas like Jacuzzis . This aspect of lighting mainly depends on the various physical properties of water ( refraction , reflection etc of stand still and moving water). Under water lighting also deals with the effects of lighting placed above water , on and in water.

The Lighting Technique is different for different purposes….

For example: Dining Lighting Techniques are different from Underwater Lighting Techniques… The kind of lights used in the Underwater Lighting system are different from that of the lights used in Dining Lighting and for specific purpose such as Task Lighting.

The material of the lights used for lighting varies for the type of ambiance it is supposed to create. The material of the underwater lights is different from the material of the other lights used for other purposes.

In this article we are going to discuss different types of Spotlights and situations where it is used.

Concealed Lighting Techniques | Methods of Lighting

Concealed Lighting Techniques

Concealed Lighting is one of the methods of Lighting Systems. Concealed Lighting is usually preferred where dim ambient lighting is necessary to enhance the beauty of the ambiance.

Concealed Lighting System
Concealed Lighting System

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

  1. Direct Lighting
  2. Indirect Lighting
  3. Concealed Lighting
  4. 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.

In this article, we are going to discuss the Evolution of the Concept of Concealed Lighting system and also how and where it is used….

Importance of Daylighting | Components of Daylight factor

Daylighting | Components of Daylight factor

Daylighting is the practice of the designing various types of openings to admit daylight into the working space for efficient and comfortable living. The orientation, shape and size of the openings play an important role in daylighting.

Daylighting could be provided with the help of windows, skylights, courtyards etc.

Daylight factor

Daylight factor can be defined as the sum of all daylight reaching an indoor reference point.

The three important components considered for the estimation of total amount of daylight reaching a particular point is as follows:

  1. Direct light of the sun
  2. External surfaces reflecting light directly to the point
  3. Internal surfaces reflecting and interreflecting light to the point

Each of the three components when expressed as a ratio or percent of the simultaneous external illuminance defines the sky component (SC), external reflected component (ERC) and internal reflected component.

Various Types of Spotlights | Spot Lighting Techniques

Spotlighting Techniques

Spotlighting is a type of lighting system usually seen to be used in stage performances… Its main function is to maintain the focus of light on the person on stage.


Depending on the use of the spotlights to be used, they are classified as follows:

  • Plano Convex
  • Ellipsoidal
  • Fresnel
  • Parabolic Aluminized Reflector [PAR]
  • PAR Pin
  • Beam Projector
  • Followspot

The above mentioned seven types of Spotlights are the most commonly used for the Lighting system in Theatrical performances…

In this article, we are going to discuss in detail the various types of Spotlights and their Lighting Mechanism and Use in detail with relevant informative pictures explaining the spotlight.

Lighting Design for Interiors | Primary Lighting Techniques

Types of Lighting Techniques | Primary and Secondary Lighting Techniques

Lighting is an art of illuminating the space in a way to create illusion. Lighting Techniques have been broadly classified into two categories:

  1. Primary Lighting
  2. Secondary Lighting

Primary Lighting and Secondary Lighting are used depending on the requirement of the kind of illumination required at a certain place. At some places, provision of only Primary Lighting would serve the purpose whereas where a meek ambiance is required, secondary lighting would serve the purpose.

Sometimes, for efficient and ambient lighting is the requirement and the cost of the lighting design is not an issue then Primary and Secondary lighting are both used in layers to create a dramatic effect.

Apart from the techniques of primary lighting and secondary lighting, the material used in the interiors also plays a vital role in creating a perfect ambiance.

Lighting Design for the Interiors and Exteriors of a Structure

Guide to Lighting Design for Interiors and Exteriors

Lighting is one of the major and important aspects of interior design exterior design as well. Aesthetics and Functionality need to go hand in hand when it comes to interior lighting techniques. Lighting design from space to space. For example, Lighting design for a museum cannot be similar to the lighting design for a residence. It changes with the purpose, its functionality, its design, area and Volume of the perceived space. These are some of the basic lighting design factors that one should consider while analyzing and designing. In this article, we will discuss in brief some of the important factors of Lighting design to be considered before deciding on the selection of a particular type of lighting technique.

Use of Fabric in a different way

There has been a huge revolution in fabric with people becoming more experimental. The trend is towards natural fibres such as cotton, linen and silk as well as to incorporating design, particularly graphic design into the fabric.

Concerns on health and safety have led to the manufacture of fire-retardant fabric and the pace of 21st century life has new demands like stain-retardant or spill-retardant features for fabric.

Materials such as Damask, silk, cotton, linen, weaves, textures, Graphic printing, Ancient ethnic prints, florals etc.
