Designing light 💡

Designing light in architecture is a complex and fascinating art. Light is a key element in creating an atmosphere and determining the aesthetics of a building. Light design can be used to emphasize architectural features, create a welcoming atmosphere, and enhance the functionality of spaces.


One of the most important aspects of lighting design is the choice of light source. The most common artificial light sources are incandescent lamps, LEDs, and halogen lamps. Each light source has unique characteristics and should be selected according to the specific needs of the project. For example, LEDs are very energy efficient and last a long time, but they can have a cooler color than incandescent lamps (now discontinued).

Lighting design must also take into account natural lighting. Sunlight can be used to create a warm and welcoming atmosphere inside buildings, but it can also cause problems such as excessive lighting and overheating. It is important to use elements such as windows, skylights, and atria to control the entry of natural light and ensure that spaces are well lit.


Lighting design must also take into account the use of the space. For example, in a kitchen it is important to ensure adequate lighting for preparing meals, while in a bedroom more subdued lighting is needed to create a relaxing atmosphere. In addition, lighting design should ideally include the use of switches and dimmers to allow users to adjust the lighting to suit their needs.

Finally, lighting design should be integrated with other elements of the architecture to create a coherent aesthetic. For example, lighting elements can be used to emphasize architectural features, such as high ceilings or windows, or to create an interesting visual contrast.

Ultimately, lighting design in architecture is a key element in creating a welcoming atmosphere and enhancing functionality.


The lighting parameters

The main lighting parameters to consider when designing light in architecture are:

1. Illuminance: is the amount of light that reaches a surface. It is measured in lux or foot-candle and must be appropriate to the needs of the environment and the activities taking place there.

2. Uniformity: is the distribution of illuminance over a surface. High uniformity means that light is evenly distributed over the surface, while low uniformity means that there are areas of light and shadow.

3. Contrast: is the difference between lighted and shaded areas. High contrast can create a dramatic atmosphere, but it can also cause eye fatigue.

4. Color rendering index (CRI): is a measure of light quality and indicates how close the light is to natural daylight. A high CRI means that the light is similar to natural light and therefore more comfortable for the eyes.

5. Flicker: is the variation in light intensity. Flickering can cause eye fatigue and headaches.

6. Lifespan: is the lifespan of the light source. Most light sources have a limited lifespan and need to be replaced periodically.

7. Energy efficiency: is the amount of energy required to produce a given amount of light. The most energy-efficient light sources are LEDs and high-pressure discharge lamps.

8. Cost: is the total cost of lighting, including the cost of purchasing, installing, and maintaining light sources.


Home automation

Home automation can be used in many ways to improve lighting design in architecture. Here are some examples:

1. Automatic lighting adjustment: home automation can be used to automatically adjust lighting according to the amount of natural light in the room and current activities. For example, it can turn on lights at dusk and turn them off in the morning, or adjust lighting based on the presence of people in the room.

2. Creating lighting scenarios: home automation can be used to create customized lighting scenarios for different activities and times of day. For example, it can create brighter, more focused lighting for working or reading, or softer, more relaxing lighting for watching TV or sleeping.

3. Remote control of lighting: home automation can be used to control lighting via mobile devices, such as smartphones and tablets, or through voice commands. This allows you to turn lights on or off, adjust the intensity, and create lighting scenarios at any time and from anywhere.

4. Integration with other systems: home automation can be integrated with other systems, such as security, air conditioning, and alarm systems, to create a smart and personalized environment. For example, it can turn on lights when the alarm is triggered to improve visibility and safety, or adjust lighting based on room temperature.

5. Data monitoring and analysis: home automation can collect data on lighting use and analyze it to optimize lighting design and improve energy efficiency.


In general, we can say that the use of home automation in architecture and the control of lighting parameters allow greater customization, control, and efficiency of lighting in a building, improving the quality of the environment and the user experience.
