Rain And Fog Days LED Lighting Advantages

- Jul 12, 2019-

The color temperature is different, and the penetrating power is different. In the visible light, the penetrating ability decreases in the order of red orange, yellow, green, blue, and purple. The lower the color temperature, the stronger the penetrating power, and vice versa.


The color rendering index of the sodium lamp is about Ra17, and the color rendering index of the ordinary LED is about Ra65 to Ra80. Due to the lack of blue spectrum of the sodium lamp, the color rendering index of the sodium lamp is low.


Under the illumination of the sodium lamp, no reflected light is emitted from the blue object, so that in the fog, the blue object will be submerged in the background light, and the person will not see the blue object. This will lead to traffic accidents. LED street lights have the advantage of high light and high light penetration in rain and fog. If you use low color temperature LED lighting, this will not happen.
