Lighting is an important element of our lives. Lighting provides us with visibility, comfort, and safety. It not only brightens up the darkness, but it can also set the mood, enhance objects, and create a certain atmosphere. Lighting can be divided into two main categories: natural lighting and artificial lighting. Natural lighting is light from the sun and moon, which is free and cannot be controlled. Artificial lighting is man-made and usually uses electricity. Light bulbs and LEDs are types of artificial light sources. In terms of lighting design, it is important to choose the right type of lighting source and the right type of lighting fixture. The right light source should provide sufficient light, be energy efficient, and be the appropriate color temperature to suit the living environment. The right lighting fixture should be able to distribute the light evenly, be suitable to the environment, stylish, and easy to install and maintain. In conclusion, proper lighting is critical to creating a visually pleasing and safe space. It can make a big difference in creating the atmosphere you want, while also meeting practical needs. Hence, it is important to take your time to choose the correct type of lighting sources and fixtures that best suit your needs.
