Advantages and disadvantages of LED street lights

◆Advantages:

1. LED street lamps have unidirectional light. Since there is no diffused light, illumination efficiency is guaranteed.

2. Unique secondary optical design. The LED street light illuminates the required lighting area, further improving the lighting efficiency to achieve the purpose of energy saving. Therefore, the biggest feature is energy saving.

3. Strong light effect. The light effect has reached 110-130lm/W, and there is still a lot of room for development, with the theoretical value of 360lm/W. As a result, overall light efficiency LED street lamps are stronger than high-pressure sodium lamps.

4. LED streetlights have high color rendering. The color rendering is much higher than that of the high-pressure sodium lamp. The color rendering index of the high-pressure sodium lamp is only about 23, while the color rendering index of the LED street lamp is above 75. From the perspective of visual psychology, to achieve the same brightness, the illumination of LED street lamps can be reduced by more than 20% than that of high-pressure sodium lamps on average.

5. Light fades. The light decay of a year is less than 3%, and it still meets the requirements of the road after 10 years of use. The high-pressure sodium light decay is large, and it has decreased by more than 30% in a year or so. Therefore, LED street lamps can be designed to use less power than high-pressure sodium lamps.

6. LED street lamp has automatic control energy-saving device. It can achieve the maximum possible power reduction and energy saving under the condition of meeting the lighting requirements of different periods. It can realize time control, computer dimming, temperature control, light control, automatic inspection, and other humanized functions.

7. Long life. It can be used for more than 50,000 hours, and we provide a three-year quality guarantee.

8. High light efficiency. Adopt more than 100LM chips, energy saving, and high efficiency.

9. Easy installation. It can be installed directly on the lamp pole or nested into the original lamp shell without burying cables and rectifiers.

10. Good heat dissipation control. In summer, the temperature can be controlled below 45 degrees, and passive heat dissipation is used.

11. Reliable quality. The circuit power supply all uses high-quality components, and each LED has separate over-current protection, so there is no need to worry about damage.

12. The light color is more uniform. No lens, not to improve the brightness at the expense of uniform light color, so as to ensure the non-aperture light color uniformity.

13. LED does not contain the harmful metal mercury, so it will not cause great harm to the environment when scrapped.

To sum up, the energy-saving effect of LED street lamps is more significant, more energy-saving. Compared with traditional street lamps, the maintenance cost of LED street lights is very low.

◆Disadvantages:

1. Low power of a single LED lamp. If you want to get high power, you need a lot of them in parallel.

2. You have light spots. Due to the defects in the manufacturing process of LED lights, it is easy to cause light spot problems.

3. Low color rendering. The colors of LED lights are not realistic enough.

4. LED light failure. High-power LED street lights are much better than low-power lamps.

5. Irradiation uniformity. LED lamps to carry out secondary optical design because LED lamp irradiation is more concentrated.
