Lighting is essential to help people create a comfortable and safe living environment. In addition to providing decoration for the visual space, correct lighting can make people feel comfortable both visually and psychologically. For indoor lighting, different areas require different lighting, whether it is a living room, bedroom, kitchen, or office. Living areas require a softer light, and the quality of the lamp can be determined according to the function and style of the area, so that the family can feel comfortable. Office lighting should be white light to improve visual effect and promote work efficiency. Ambient lighting should also take into account the different colors of the wall, furnishings, and other details in the area, such as ceiling light, table lamp, wall lamp and floor lamp. At night, when the external environment is relatively dark, the area needs accent lighting to maintain the environment and lighting can also ensure people's safety. In conclusion, in order to create a warm, comfortable and safe living environment, correct lighting is essential. Different areas in the home require different types of lighting, so the quality of the lamp should be taken into consideration.
