Lighting, which plays an important role in our life, is the process of igniting a flame, creating an area of ​​visibility in the dark, decorating the environment, and influencing the atmosphere of a place. Lighting is diverse and does not just mean attaching light fixtures. As a homeowner, you can inject your own style into your living space by combining lighting with decoration and furniture. Lighting can create focal points, define a space, and create a particular atmosphere. The lighting in interior decoration can be divided into two categories: artificial lighting and natural lighting. Artificial lighting usually comes from electric lamps or lighting fixtures, such as chandeliers, pendant lights, wall lamps, and floor lamps. Natural lighting is sunlight and moonlight that can be used to illuminate most of the day. Using natural light in an interior setting often requires proper window treatments and blinds to regulate the lighting. The application of lighting in interior design requires a good understanding of three basic elements: brightness, color, and direction. Brightness is the measure of light energy, which is usually measured in lumens, lux or candelas. Color is determined by its Kelvin temperature. And direction is the orientation of the light source in relation to the subject. It is essential to choose the right lighting for each environment. It helps to create a cozy and warm atmosphere or a vibrant and dynamic atmosphere. It is also important to remember that the lighting should also be aesthetically pleasing and bring out the texture and color of the furniture and walls. In conclusion, lighting plays an important role in interior design. With the right lighting, you can create the perfect atmosphere and bring out the beauty of your interior.
