In our lives, public lighting is usually more common in warm light, more suitable for street and public lighting.
Color is an important factor to consider when looking for the right LED street light for your project, as it is closely related to the safety of the driver and passengers. It turns out that warm light has better light transmission than white or cold light. In addition to this, the problem of urban sky lighting (lighting pollution) is attributed to street lamps with low penetration. Illumination pollution on the sky affects astronomical research because when the sky is too bright, the observer cannot clearly see the star motion.
According to recent research, the blue light will inhibit the secretion of melatonin, a hormone that helps maintain our internal clock and affects our mood and reproduction. This also proves that this hormone has a great impact on our immune system. As a result, many countries tend to use yellow or amber street lights to eliminate blue in residential areas.
The introduction of daylight-like streetlights in rural areas will disrupt the metabolic cycles of plants and animals, especially at night. Bright white light interferes with their perception of day and night, affecting their hunting and migrating in their lives. For example, turtles are attracted by white light and they are hit by cars when they reach the road. Because turtles are more sensitive to white than yellow lights, it is mandatory to use turtle-friendly yellow street lights in some countries, such as the United States.
