What color temperature should be more suitable for LED street lights?

Unknowingly, the New Year’s Christmas is approaching, and there seems to be a lot more pedestrians than usual on the streets in the evening. Christmas night is particularly beautiful under the illumination of LED street lights. Some of the LED street lights on the street emit yellow light, and some emit white light. In our impression, the LED street lights in the city generally emit warm yellow light, and the LED street lights on a small part of the road emit white light. Why is it so? In fact, the difference between yellow light and white light lies in the choice of the color temperature of the LED street lamp, so what color temperature should be used for the LED street lamp more appropriate? Next, the editor of the LED street light manufacturer will briefly talk about this issue.

The color temperature of LED street lights emits white light around K, and yellow light or warm white light around K. In fact, the yellow light or warm white light around K is more suitable for road lighting, while the color temperature of LED street lights around K is not suitable for road lighting. Because the color temperature of K will make people visually very cold and dazzling, resulting in excessive visual fatigue, and under this color temperature condition, people's ability to observe from a distance will also decrease, reducing the driver's driving safety. In addition, in rainy and foggy weather, LED street lights with K color temperature have poor penetrating ability, which also affects the safety of pedestrians. So why are there still many LED street lights that use this color temperature in many areas?

First, when the early LED street lamps first came out, many LED street lamp manufacturers chose a color temperature of about K, which led to many manufacturers to follow suit.

Second, under the conditions of early phosphor technology, LED street lamps with cool white light sources have higher luminous efficiency.

Third, today's LED street lamps lack strict technical standards in terms of product specifications.

The above three reasons have led to the rampant use of K color temperature LED street lights in the market, which is not a good thing for pedestrians. In short, the editor believes that LED street lights with K warm color temperature have more advantages, and have more user experience than K color temperature. To improve this situation, LED street lamp manufacturers should recommend warm color temperature to engineering companies, and engineering companies themselves must change the old idea of u200bu200bexclusive white light for LED street lights.
