Why Lighting Is Important In Interior Design?

In interior design, light is used to:

  • create moods,
  • direct attention,
  • highlight objects,
  • emphasize a point,
  • and add another dimension to a space.

The first step in creating a good interior design is choosing the right lighting.

Good lighting can really make a huge impact on the overall look and feel of your room. When you think about how the human brain perceives light, it really helps to understand how we see objects in our environment.

How the human brain perceives objects

We see objects as black and white when light hits them at an angle.

The more an object reflects light, the brighter it appears. This is how we perceive objects when we see them under different lighting conditions. A lot of designers are familiar with the concept of light, shadow, and color, which can be used to design spaces with great impact.

Lighting – the first thing to notice

Lighting is often the first thing that people notice when they walk into a room.

It’s also one of the easiest things to change to improve a room’s appearance. If a room isn’t lit properly, you may end up with a cluttered, unappealing space.

And there are a lot of ways to go about this, from LED lighting to the use of lamps and other fixtures.

How to use light effectively in interior design

Light is crucial to creating a welcoming atmosphere in your home.

It’s one of the first things people notice about a room and can make a space feel cozy, romantic, or open. If you’re designing a space, take into account the following light principles:

Create the Illusion of Depth

Using light effectively can make your space appear larger.

This is especially true in small spaces. You can easily create the illusion of depth by using soft and diffused light.

When it comes to lighting, the key is to use indirect lighting whenever possible. This will help to create an illusion of depth in a room. When you illuminate the room with light, the light source will cast shadows on the walls.

Create the Right Mood

As any good interior designer knows, lighting makes a huge difference when it comes to mood.

If you want a calm room – go for soft light.

A more active, boisterous room will benefit from more aggressive lighting.

Choose the Right Type of Light

A light source should be chosen based on what the room will be used for and how the space will be utilized.

When choosing a lamp or light fixture, one should consider how they will be used, where they will be placed, and how much natural light the room gets.


A great lighting scheme will create a comfortable environment, boost productivity, improve creativity, make a room look more spacious, increase energy efficiency, and add to the aesthetics of your home.

It’s a very important element of interior design and it’s also something that can either enhance or detract from the atmosphere you are trying to create. Lighting is like a catalyst for any project.

Now when you know why lighting is important in interior design, it’s up to you to choose it and use it the way you want to.
