Lighting plays a very important role in our lives. It has the effect of guiding us, illuminating our lives, helping us to interact with others, create an atmosphere and so on. Lighting can affect the mood of any space. For example, a yellow light will make the room comfortable and cosy, while a whiter and harsher light is good for work and outdoor activities. Smart lights can be adjusted to different brightness levels, colours and temperatures, creating a range of lighting scenarios for different occasions. Lighting can also improve safety and security. By having sufficient lighting in dark spaces, crime rates can be reduced. Proper lighting can also deter criminals from areas and increase public awareness and security. Using lighting to draw attention to key areas on a property can also help with energy efficiency. When arranging a space, it is important to consider the type of lighting that is best for the space and the activities it is used for. For example, in a cafe, the lighting should be dimmer and a lighter colour to create an inviting and relaxing space. In offices, lighting should enable easy working, such as having task lighting nearby to help with desktop tasks. In closing,lighting is an essential element in creating the atmosphere of any space. Lighting serves a variety of purposes, from helping people to feel secure and creating a pleasant atmosphere to helping people to work efficiently and safely. Therefore, it is important to consider different types of lighting for different needs and occasions.
