In daily life, the color temperature of ordinary incandescent lamps is about 2800K, halogen lamps about 3400K, fluorescent lamps about 6500K, warm white fluorescent lamps about 4500K, and high-pressure sodium lamps about 2000-2100K. It is essential to understand these values as a basis for the replacement of traditional lamps with solar yard lights.
After understanding how color temperature affects feelings in different lighting situations, it is observed that low color temperature light creates a pleasant and comfortable atmosphere in low illumination conditions; high color temperature can create a gloomy, dim, and cool feeling; in high illumination settings, low color temperature light can make one feel hot; conversely, high color temperature can create feelings of comfort and happiness. Workplaces require high illumination and high color temperature environments, while relaxation areas require low illumination and low color temperature settings.
Solar intelligent street lights emit white light with a color temperature of around 5000K and yellow or warm white light around 3000K. In fact, yellow or warm white light around 3000K is more suitable for road lighting, while the 5000K color temperature of solar intelligent street lights is not appropriate for this purpose. The 5000K color temperature can cause a cold and glaring appearance, leading to visual fatigue. Under such color temperature conditions, a person’s ability to observe from a distance may decrease, which can ultimately reduce driving safety.
