Natural Light and Its Benefits

Light is the smallest quantity of energy that can be transferred.

Natural lighting is light coming from the sun, stars, or fire. It's a technique for bringing natural light into buildings using windows, skylights, etc. This helps save energy by reducing the need for artificial lighting.

Natural lighting is good for health, mental well-being, and sleep. It provides Vitamin D, helps prevent depression, and improves sleep quality.

Direct sunlight is light coming straight from the sun through windows or skylights.

External reflection is when light bounces off surfaces outside the building, like the ground, other buildings, or light shelves.

Internal reflection is when light bounces off surfaces inside the building, like walls, ceilings, and floors.

There are three main sources: Direct Sunlight, External Reflection, and Internal Reflection. Each source brings natural light into a building in different ways.

Artificial lighting is light produced by human-made sources, such as light bulbs, lamps, or LED displays.

General lighting for everyday activities, providing an even spread of light for comfortable visibility and safe navigation.

Specific lighting for focused activities like reading or working, used when ambient light isn't enough.

Lighting used to highlight specific features or add character to a space, creating drama.

A combination of art (architecture) and technology (lighting) to illuminate buildings while considering design and function.

Focusing on the emotional impact of lighting and architecture on people. Designers determine how they want occupants to feel in a space.

Ensuring safety and visibility within a building. Occupants should be able to see clearly and navigate confidently.

Designing breathtaking lighting layouts while considering energy consumption and minimizing waste.

Artificial lighting has significantly extended human productivity, enabling work and activity beyond daylight hours, and it can even help with mood.

A traditional light bulb with a filament that glows when electricity passes through it. While inexpensive and instantly bright, they are energy inefficient.

A more energy-efficient alternative to incandescent bulbs, often in compact forms, offering various shapes and sizes.

A highly energy-efficient light source that lasts much longer than incandescent bulbs, despite being more expensive.

LEDs use significantly less electricity than incandescent bulbs and last much longer, making them cost-effective in the long run.

CFLs are used as substitutes for incandescent bulbs in many applications, offering a more efficient lighting solution.

Incandescent bulbs have a filament that glows, while LEDs are electronic devices that emit light. LEDs are more energy-efficient and last much longer, but they can be more expensive initially.
