1, Principles for Setting Linear Lighting Spacing
Functional principle: Firstly, the spacing of linear lighting should be set based on the functional requirements of the space. For example, in commercial display areas, in order to highlight product details and colors, the lighting spacing should be relatively small to ensure comprehensive and uniform light coverage; In the office area, in order to create a peaceful and focused working atmosphere, the lighting spacing can be appropriately increased to avoid glare and visual fatigue.
Aesthetic principle: In addition to functionality, the spacing of linear lighting should also consider coordination and aesthetics with the overall style of the space. Reasonable spacing can enhance the sense of hierarchy and rhythm in space, making the light and shadow effects more harmonious and unified. Designers should flexibly adjust the lighting spacing based on spatial characteristics, material colors, and other factors to achieve the best aesthetic effect.
Economic principle: On the premise of meeting functional and aesthetic requirements, the spacing setting of linear lighting also needs to consider economic efficiency. An overly dense layout will increase the number of lighting fixtures and energy consumption costs; However, a layout that is too sparse may result in insufficient lighting or obvious light spots, affecting the lighting effect. Therefore, it is necessary to control the lighting spacing reasonably while ensuring the quality of lighting, in order to maximize economic benefits.
2, Factors affecting linear lighting spacing
Light source type and power: Linear light sources of different types and powers have different emission characteristics and illumination ranges. Therefore, when selecting a light source, it is necessary to fully consider its luminous characteristics and lighting requirements to determine the appropriate lighting spacing.
Space height and width: The height and width of a space are also important factors that affect lighting spacing. Generally speaking, the higher and wider the space, the greater the lighting spacing should be; On the contrary, it should be appropriately reduced. To ensure that the light can evenly cover the entire space and avoid creating dark areas or light spots.
Wall and floor materials: The materials of the wall and floor have different abilities to reflect and absorb light, which can also affect the setting of lighting spacing. For example, a smooth surface has strong reflective ability, and the lighting spacing can be appropriately increased; If the rough surface has strong absorption capacity, it is necessary to reduce the lighting spacing to ensure the lighting effect.
3, Specific calculation method for linear lighting spacing
There are various specific calculation methods for linear lighting spacing, including methods based on illuminance calculation, visual comfort evaluation, and empirical formula. Among them, the method based on illuminance calculation is more scientific and rigorous. It calculates the reasonable lighting spacing through mathematical formulas based on factors such as the required illuminance level of the space, the luminous intensity of the light source, and the lighting efficiency. However, this method requires detailed data support and complex computational processes, which may be limited in practical applications.
In contrast, the empirical formula based method is more simple and feasible. Some professional lighting design manuals or software provide recommended lighting spacing values or calculation formulas for different application scenarios, and designers can choose and adjust them according to specific situations.
4, Practical application cases
In commercial display areas, in order to highlight the display effect of products, a dense layout of linear lighting is usually used. For example, in jewelry stores, in order to highlight the dazzling luster and exquisite craftsmanship of jewelry, dense LED line lights are often set up above display cabinets, with lighting spacing of only a few tens of centimeters or even smaller. In the office area, in order to create a comfortable working environment, the spacing of linear lighting is relatively large, usually set between 1 meter and 1.5 meters, to ensure soft, uniform and glare free light.
