Lighting plays an important role in all aspects of human life and has different effects in different places. It not only affects the aesthetics of architecture and space, but also affects the life of people. In a work environment, lighting can help them focus on their work to have better efficiency. For example, natural sunlight can provide a comfortable working experience that will keep employees productive and energetic. On the other hand, lighting can also reduce eye strain caused by long hours of work in front of a computer. In a home, lighting can help to create an inviting atmosphere. In the living room, soft lighting helps to create a cozy and comfortable feeling, while bright lighting can be used to create a casual and lively atmosphere. Additionally, task lighting such as table lamps can help people focus when reading or studying. In a store or a restaurant, lighting can make people feel comfortable enough to stay longer and create a more relaxed atmosphere. For retail stores, lighting can draw attention to products on display and create an inviting space. For restaurants, lighting can create an atmosphere that is both inviting and attractive. Lighting can also be used for decoration and can add a unique look to any space. By using lights with different intensities, shapes, sizes and colours, one can create different moods and looks for any space. In summary, lighting not only affects the look and feel of a space, but can also affect the productivity of people and create a more pleasant and inviting experience.
