Shedding Light on Lighting Design Concepts

May 19, 2023 | Journal

Lighting is an essential aspect of interior design that can transform a space from ordinary to extraordinary. As technology continues to evolve, so does the world of lighting design. From energy-efficient LED lights to interactive lighting systems, lighting design concepts are changing the way we experience light in our homes and businesses.

The Role of Light in Design

In visual environment design, light is essential, as it allows for work and movement by making architecture, people, and objects visible. The role of lighting design concepts in how we perceive and respond to our surroundings cannot be overstated, affecting both our feelings and reactions.

Understanding LUX, Lumens, and Other Lighting Terms

Luminous Intensity

Luminous intensity is an important measurement when it comes to visible light in a specific direction per solid angle. It is measured in candela (cd), which is the standard unit of measurement.

Luminous Flux

Luminous flux is another important measurement that measures the output of visible light from a light source, such as a lamp. Its standard unit of measurement is the lumen (lm). It is important to note that the luminous flux of a light source can vary depending on the direction the light is emitted.

Lux and Illuminance

Lux is the standard unit for measuring illuminance and luminous emittance. It measures the luminous flux per unit area. One lux is equal to one lumen per square meter. It is important to note that the illuminance level required in a typical home can vary depending on the size of the room and the intended use of the room. For example, a kitchen may require a higher illuminance level than a bedroom.


Power refers to the electrical energy required by the lamps in the context of lighting. It is typically measured in watts (W). It is important to note that the power requirement of a lamp can vary depending on the type of lamp and the intended use of the lamp. For example, a lamp used for reading may require a higher power output than a lamp used for mood lighting.

Considerations for Your Lighting Design Scheme

Lighting design goes beyond determining the correct lux level and lighting intensities; it caters to both the physiological visual requirements and emotional needs of users. Three main types of environments necessitate different lighting design approaches:

  1. Work environments and public places prioritize functionality, safety, and communication.
  2. Exhibition and sale environments focus on the exhibit and the user’s viewing experience.
  3. Residential or touristic environments aim to create an atmosphere of comfort and relaxation.

In each of these, one must consider function, behavioural effects, aesthetics, budget, light and shadow play, direct and indirect light, light colour, task lighting, ambient lighting, and light control.

Emphasizing Functionality in Design

Determining the function of a space is essential, as it guides decisions regarding glare, visual comfort, and task illumination. Current regulations and standards provide specific lighting requirements for different tasks. It’s also crucial to understand the activities that will take place, their frequency, and the time of day they will occur.

Influence of Lighting on Behaviour

Lighting plays a critical role in shaping the way people behave, and it is essential to consider its potential impact on users when designing. While lighting can have a positive impact on health and behaviour, it can also have negative effects if not used correctly. For instance, bright lighting can be stimulating and help people stay focused, but harsh or flickering lights can cause headaches and eye strain.

Aesthetics and Budget

Our perception of space can be profoundly influenced by lighting. A well-executed architectural design can be rendered dull with poor lighting design concepts, while clever lighting design can improve an otherwise unimpressive space. Also, keeping the project within budget is a must, often requiring creative solutions to achieve desired effects without overspending.

Light and Shadow

A successful lighting design creates texture and depth by designing varying levels of light, producing soft shadows that draw attention to lit areas. This can be used to emphasize a room’s main features. To create the illusion of a larger room, illuminate the walls with the brightest light to make the entire room visible and reflect more light into the space.

Understanding Direct and Indirect Light

Direct light shines directly from a lamp into a room, providing bright and more focused illumination, but it can also cause glare. Indirect light reflects off a surface, diffusing across it to provide a relaxed atmosphere with less eye strain. To avoid blandness, a combination of light and shadow can be used to offer visual interest.

Choosing the Right Colour of Light

The colour of light can have a significant impact on the overall atmosphere of a room. By selecting the right colour, you can create a space that is perfectly suited to your needs. For example, cold colours that contain bluer can create a stimulating and energetic environment, which is perfect for workspaces or areas where you need to be alert and focused. On the other hand, warm colours with more red can generate a relaxing, comfortable environment, which is ideal for areas such as living rooms and bedrooms.

Task Lighting

Task lighting is an essential part of any lighting design concept. It provides additional light for specific tasks in a room where ambient lighting won’t suffice, such as reading or cooking. To ensure that task lighting is effective, it should be free of distracting glare and shadows. Additionally, it should be bright enough to prevent eye strain, but not so bright that it causes discomfort.

Ambient Lighting

Ambient lighting is another critical component of any lighting design. It provides a room with overall illumination, creating a comfortable level of brightness without glare. This type of lighting is essential for ensuring that you can see and walk about safely in a room. There are many different types of fixtures that can be used to achieve ambient lighting, including chandeliers, ceiling or wall-mounted fixtures, recessed or track lights, and even table and floor lamps.

Light Control

Controlling the light in a room is an often-overlooked aspect of lighting design, but it can make a significant difference in the overall atmosphere of your space. There are many different ways to control the light in a room, from adjusting the intensity with dimmers to changing the direction of the light source. By having more control over your lighting, you can adjust the ambience of your space to suit different moods or times of the day. For example, you might want to create a more relaxing atmosphere in the evening or a more energizing environment during the day.

Frequently Asked Questions about Lighting Design Concepts
