Lighting is essential for human life as it gives out light and electricity to many places, making us visible, comfortable and safe. It not only works as illumination for us to see, but also creates a mood of relaxation and dignity. Lighting also functions to increase security and safety, protect our health and even signal emergencies. To choose the right lighting, you should consider the convenience and safety of the lighting environment, as well as the artistic beauty of space. Good lighting must have the appropriate amount of brightness, and should use energy efficient and environmentally friendly lighting sources to help protect the environment, conserve resources, prop up economic development and improve public health. Lighting can be broadly divided into naturalambient lighting and artificial lighting. Natural ambience lighting is divided into three categories: sunlight, moonlight and starlight. Sunlight has better brightness than artificial lighting; while moonlight is more suitable for nighttime lighting and starlight can give a special atmosphere. Artificial lighting is divided into two types: electric lighting and acoustic lighting, and can be further classified into many different categories. Overall, lighting plays an important role in highlighting beauty, creating atmosphere, protecting our health and improving safety. Depending on the specific needs of a space, the right lighting can be selected to bring a pleasing atmosphere and numerous benefits.
