Lighting refers to the application of light in space. The position, relative intensity and direction of light have a significant impact not only on vision and visual comfort, but also on human perception. In addition to light, the lighting itself affects the experience of the space and its owners.
Lighting can affect the degree of satisfaction, visibility, performance, safety, security, sales, and mood and atmosphere, aesthetic judgment and social interaction, can also tell a story about space, let the customer know that store is focused on discount, or a high-end products, or a restaurant is selling fast food, or dining experience.
Light Color Perception: For an object to perceive a certain color, its color is usually reflected in both the object and the amount of light shining on it. Designer a particular focus on the appearance of the color (general with correlated color temperature (CCT) measured) and color fidelity, or with standard light source (generally sunlight do standard light source) contrast of color rendering (to color rendering index (CRI), the higher the color rendering index, shows that the better light source color rendering, color reproduction ability of an object.) The lighting industry is also evaluating a metric that captures saturation. In general, changing CCT, CRI, and saturation can have a big impact on the appearance of people, objects, and Spaces, enhancing, weakening, and even changing their original colors.
Focus of light: The human eye is naturally drawn to the brightest areas in the field of view. By focusing higher intensities of light on certain features in space, we can bring them into focus, directing people’s attention to them and establishing visual hierarchies. For example, we can promote the display of key goods by focusing light at a higher intensity.
Spatial perception of light: Different light patterns in space can stimulate different psychological responses (as shown in the table below). For example, bright and even lighting, shining light on the walls or even the ceiling, can make the space in the hall appear more public and visually larger. By contrast, low-intensity lighting and a little peripheral light can create intimacy in a good restaurant.
