Lighting is an important part of our lives. The quality of lighting affects our mood, energy and productivity. Artificial lighting not only brings people light but also provides people a feeling of safety. In addition, lighting has been successfully used to improve the overall atmosphere of a room. Light sources are often classified into two categories: natural and artificial. Natural lighting comes from the sun or the moon. Natural lighting is abundant and free of charge, is the most environmentally friendly form of lighting and does not require electrical energy. Artificial lighting uses electrical power to generate light of different intensity and in different colors. Common examples include incandescent bulbs, halogen lamps, fluorescent lamps, and LED lights. LED lights are rapidly becoming the most popular choice due to their energy efficiency and long lifespan. With the advancement of technology, lighting can be used in various applications. Lighting is fundamental in creating the atmosphere for a certain design. This includes its usage in retail stores, showroom, residential houses or offices. Today, it is not just about illumination, but also aesthetics. People can customize the atmosphere with dimmable lighting and decorative designs. Advanced lighting systems can also be used to save energy by automatically turning on and off the lights depending on the environment. IoT also opens up a vast range of possibilities such as setting up smart homes and adjusting lighting according to the needs. In conclusion, lighting is an integral part of our lives. It plays an important role in different aspects such as creating atmosphere, providing safety, and saving energy. With the rise of new technologies, the possibilities with lighting become more exciting.
