ighting Design Principles and Parameter Configuration Guide for Different Scenarios

Lighting design is to reasonably select lighting products, layout lamp positions, and optimize lighting parameters according to the functional needs and spatial characteristics of the usage scenario, so as to achieve a comfortable, efficient, and safe lighting effect. The lighting needs of different scenarios vary significantly, and corresponding design principles and parameter configuration standards must be followed.​
The core principle of home lighting is comfort, warmth, and personalization, and the design must be carried out according to the functional characteristics of different rooms. As the center of family activities, the living room should adopt a combination of main lighting and auxiliary lighting. For the main lighting, 20-30W LED ceiling lamps or chandeliers can be selected, with the illuminance controlled at 300-500lx, the color temperature at 3000K-4000K, and the color rendering index Ra ≥ 90. For auxiliary lighting, floor lamps and wall lamps can be configured for local lighting and atmosphere creation. The bedroom lighting should focus on softness and anti-glare. For the main lighting, 15-20W LED ceiling lamps can be selected, with the illuminance at 200-300lx and the color temperature around 3000K to avoid strong light stimulation. Adjustable-brightness desk lamps or wall lamps can be configured beside the bed to facilitate reading and rest. The kitchen lighting must balance functionality and safety. For the main lighting, 15-20W LED panel lamps can be selected, with the illuminance at 500-700lx and the color rendering index Ra ≥ 85 to ensure sufficient light in the operation area. Local lighting can be configured in key areas such as the stove and sink to avoid the impact of shadows on operations. The bathroom lighting must have waterproof and anti-fog functions. For the main lighting, 10-15W waterproof LED lamps can be selected, with the illuminance at 300-500lx and the color temperature at 3500K-4000K. Anti-fog vanity lamps can be configured above the mirror to ensure the clarity of makeup and shaving operations.​
The core principle of commercial lighting is to highlight the characteristics of goods, improve the shopping experience, and promote consumption conversion. Shopping mall lighting should adopt a zoned lighting strategy, with the illuminance in public areas at 300-500lx and the color temperature around 4000K. The window lighting should highlight the details of the goods, with the illuminance at 1000-2000lx and the color rendering index Ra ≥ 90, and use key lighting to highlight core goods. Clothing store lighting should focus on color reproduction, with the color temperature at 3500K-4500K and the color rendering index R9 ≥ 50 to ensure the true presentation of clothing colors. Hotel lighting should create a warm and high-end atmosphere. The main lighting in the lobby can have an illuminance of 500-800lx and a color temperature of 3000K-3500K, and crystal lamps and wall lamps can be matched to enhance the grade. The guest room lighting is similar to home lighting, focusing on comfort and privacy, with the illuminance at 200-300lx and configurable adjustable-brightness lamps.​
The core principle of public lighting is safety, efficiency, and energy conservation. Road lighting must ensure driving safety, with the illuminance of main roads at 15-30lx, secondary roads at 10-20lx, and the color temperature at 3000K-5000K. Anti-glare design should be adopted to avoid affecting driving vision. The illuminance of sidewalk lighting should be 5-10lx, focusing on pedestrian comfort. Square lighting should balance the needs of activities and landscape effects, with the main lighting illuminance at 200-300lx, and landscape lamps and floodlights can be matched to create an atmosphere. Park lighting should highlight the natural landscape, using low-brightness and warm-color-temperature lamps, with the illuminance at 50-100lx to avoid light pollution.​
Lighting design must also follow general principles such as illuminance uniformity, glare control, and color coordination to ensure that the lighting effect not only meets functional needs but also conforms to human visual habits.
