Lighting plays an important role in life. It is part of our daily life, and the lighting environment of our living space directly affects our physical and mental health. Lighting fixtures generally refer to a group of luminous devices, which fall into two main categories: artificial lighting and natural lighting. Natural lighting refers to the light from the sun, the moon, and other external luminous sources, which has the most direct, most natural and most abundant illumination effect. Artificial lighting mainly consists of lamps, which are divided into various categories according to their light sources, such as fluorescent lamps, energy-saving lamps, incandescent lamps, LED lamps, and halogen lamps. Artificial lighting can satisfy our needs for different illumination environments in different spaces, and help us to live and study without being affected by external natural light changes. Lighting can set off a pleasant atmosphere, creating a comfortable and warm living environment. To make the home atmosphere so comfortable, lighting devices such as ceiling lamps, wall lamps and floor lamps should be used. The bedside lamps can create the atmosphere of romantic and peaceful for a couple; the desk task lamps are ideal for creating the environment of study and work; and the art lamps are ideal for making the space more artistic and can serve as a part of the decoration. In a word, lighting not only helps us to increase the vision for activities, but also can beautify the environment and improve the quality of life. Therefore, when choosing lighting equipment, people should consider both practicality and aesthetics to meet their different needs.
