Why don't you choose white light for the luminous color of street lights, but choose warm yellow instead?
Have you noticed that the street lights on the road generally have a warm yellow light, and you rarely see white light. There is a lot of darkness on the road. It is very dangerous to walk in the dark at night. I can’t see what’s ahead and I don’t know the surroundings. What dangers exist can easily cause all kinds of accidents. Therefore, the existence of street lights not only illuminates the dark night, but also improves people's night safety.
The installation of street lights is to consider the factor of viewing angle, even if the illumination does not illuminate very far, warm yellow light will be selected. So why did you choose warm yellow light?
Staring at the white light for a long time will feel very dazzling and make the eyes very uncomfortable. Even for a short period of time, the front of the eyes can't be seen clearly.
The warm yellow color is very gentle. Even if you stare for a long time, it will only make your eyes feel a little awkward. It will not be as serious as white light. Therefore, when choosing the light color of the street lamp, you must consider many aspects, don't just ask for a brighter light. ,farther.
In terms of light, the luminous intensity of white is indeed much higher than other colors, and it can also illuminate more places and make the field of vision more open, but this kind of strong white light is not perfect. If you use this kind of street lamp in a city Illuminating colors, with the aid of advertising light boxes, neon lights and shop lights, will not feel very tired. If you are on a very empty loop, the visual fatigue will be infinitely magnified. This is what we usually call white light to dazzle the eyes.
In contrast, yellow warm lights will not cause this phenomenon, which is the main reason why most street lights choose yellow.
Most of the white light will be very dazzling, it is characterized by the fact that it shines brightly and far away. Choose the appropriate light-emitting color according to the situation.
Advantages of LED street lights:
1. The characteristics of the LED street lamp itself-the one-way light, no light diffusion, to ensure the light efficiency.
2. The LED street lamp has a unique secondary optical design, which irradiates the light of the LED street lamp to the area that needs to be illuminated, and further improves the light efficiency to achieve the purpose of energy saving.
3. The luminous decay is small, the one-year luminous decay is less than 3%, and it can still meet the road use illuminance requirements after 10 years of use, while the high-pressure sodium lamp has a large decay, which has dropped by more than 30% in about one year. Therefore, the LED street lamp is in the use of power Design can be lower than high pressure sodium lamp.
4. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements at different times.
5. LED is a low-voltage device. The voltage to drive a single LED is a safe voltage. The power of a single LED in the series is 1 watt, so it is a safer power supply than the use of high-voltage power supplies. It is especially suitable for public places (such as street lights). Lighting, factory and mine lighting, automotive lighting, civil lighting, etc.).
