Lighting is an integral element in the design and function of a space. Not only does lighting provide the illumination necessary for visibility and safety, but it can also be used to create a mood or set the atmosphere for a particular space. The types of lighting used and how it is implemented can make a drastic difference in the overall feeling of a room. In addition to the type of light that is chosen for a space, one needs to consider the amount of lighting to use. Bright lights that may be needed for activities can be harsh for relaxation; while dim lighting may be good for relaxation, but too dim can cause stress and eyestrain. Additionally, bright lighting requires more energy to create and often come with additional heat. This is why a variety of lighting strategies are often used to create different moods at different times. LED lighting can be used to simulate ambient daylight or sunlight for a feeling of openness and largeness while wall washers can create light patterns to enhance the shape and size of a room. One of the main and most important benefits of using good lighting is its impact on the human psyche. Properly used lighting can have an effect on our alertness and creativity. Common options like down lighting, spot lighting, and task lighting are great for areas where reading, working, and other activities take place. In conclusion, proper lighting is an important element in any room to create an atmosphere and make the room more functional. The best lighting plan always has multiple types of lighting to use for different times and activities to create the desired atmosphere and mood.
