Lighting is an important element for a comfortable living space. A good indoor lighting design can make people feel comfortable and relaxed, while a poorly designed lighting will make people tired and depressed. The types of lighting used in the home are various. General lighting includes lighting such as ceiling lights or downlights, which provide uniform illumination throughout the room. Task lighting is a type of lighting used for specific activities such as reading or cooking in the kitchen. The purpose of task lighting is to provide a focused and sufficient light that will not disturb the other inhabitants of the room. Accent lighting is also important for highlighting artwork and other items to create an atmosphere of comfort and delight. The place of lighting is also important. General lighting, such as ceiling lights or downlights, should be placed in the middle of the room since it will provide uniform light in the room. Task lighting should be placed near the task place. The intensity of the lighting is also important. For general lighting, it should be bright enough to illuminate the entire room, but not too bright to make people uncomfortable. For task lighting, it needs to be bright enough to light up the task place, but not too bright to cause glare. Besides, accent lighting should also be used appropriately, so that its purpose of highlighting the artwork can be achieved. In conclusion, lighting has a great impact on people's psychology, comfort and aesthetic. Therefore, the types of lighting, the place of lighting, the intensity of lighting all need to be considered in order to achieve maximum comfort and enjoyment.
