From a visual perspective, different color temperatures will bring completely different effects. Warm white light (2700K - 3500K) can create a warm and comfortable atmosphere, just like soft moonlight, adding a sense of romance and tranquility to parks, courtyards and other places, allowing people to feel the warmth of home outdoors. Pure white light (4500K - 5500K) is close to natural light, bright and comfortable. In scenes such as road lighting and square lighting, it can provide clear visual effects, allowing people to clearly see the surrounding environment and things, and ensure travel safety. Cold white light (5700K - 6500K and above) is bluish, giving people a bright and refreshing feeling. It is suitable for outdoor environments that need to emphasize modernity and technology, such as facade lighting of modern buildings, street lights in science and technology parks, etc., but if used improperly, it may produce a dazzling feeling.
In terms of ecology, color temperature also has an important impact. For example, warm white light with a lower color temperature is relatively less attractive to insects, which helps reduce interference with insect ecology and protect nocturnal insects and other organisms that depend on them. Cold white light with a high color temperature may attract a large number of insects to gather, affecting their normal living habits, and may even have an adverse effect on the reproduction of some insects. At the same time, for plants, light of different color temperatures will also affect their photosynthesis and growth rhythm to a certain extent.
In addition, color temperature adjustment is also related to energy utilization and environmental protection. According to different environmental requirements and time periods, the color temperature of LED outdoor lights can be reasonably adjusted to reduce energy consumption while ensuring the lighting effect. For example, in the middle of the night, appropriately lowering the color temperature of street lights can not only meet basic lighting needs, but also reduce unnecessary energy waste, thereby reducing carbon emissions and contributing to environmental protection.
