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.
Lighting systems | Illumination Techniques
Lighting Systems comprises of two main 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
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.

Lighting Techniques play a very important role in creating soothing ambience. It could be a room, a residence, a building facade or ambient lighting in the Landscaped Gardens…
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
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.
Here are some of the other lighting methods apart from concealed Lighting:
- Direct Lighting
- Indirect Lighting
- Concealed Lighting
- 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….
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 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:
- Direct light of the sun
- External surfaces reflecting light directly to the point
- 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.
