Advantages and Disadvantages of Using LED Street Lights

Now, street lights are ubiquitous in urban areas, and they facilitate and safeguard our daily lives. After years of development, LED lights are now mostly employed in street lighting. Compared to high-pressure sodium lamps, LED street lights provide additional advantages.

1. It is a unidirectional light source devoid of light diffusion, guaranteeing optimal light output.

2. The LED street light features a unique secondary optical design that irradiates the light of the lamp to the region that needs to be lighted, so enhancing the light efficiency and achieving the energy-saving objective.

3. The luminous efficiency of LEDs has reached 130-150lm/W, with a potential value of 360lm/W still available for improvement. Increasing the wattage of high-pressure sodium lights boosts their luminous efficiency. Therefore, LED street lights have a greater total luminous efficiency than high-pressure sodium lamps.

4. LED street lights provide far better color rendering than high-pressure sodium lighting. The color rendering index of high-pressure sodium lamps is around 23, whereas that of LED street lights is more than 75. In terms of visual psychology, the amount of LED light required to attain the same level of brightness as a high-pressure sodium lamp is more than 20% less.

5. The light decay of LED light is minimal, at less than 3% per year, and it still fulfills road regulations after 10 years of usage, but the light decay of a high-pressure sodium lamp is substantial, at more than 30% per year. Therefore, LED street lights may be designed to use less energy than high-pressure sodium lamps.

6. The LED street light is equipped with an automated control energy-saving mechanism that can achieve the best possible power and energy savings under the condition of fulfilling the illumination needs at various times. It is capable of computer dimming, time period control, light control, temperature control, automated inspection, and more humanized tasks.

7. It may be used for over 50,000 hours and comes with a three-year quality guarantee. However, it is impossible to guarantee battery life.

8. Using chips 200LM, LED street lights may save about 75% more energy than standard high-pressure sodium lamps.

9. It is simple to install, requiring no underground wires, rectifiers, etc., and may be immediately connected to the light pole or nestled into the original lampshade.

10. The temperature in the summer is kept below 45 degrees, passive heat dissipation is used, and summer heat dissipation is inadequate.

11. All circuit power supplies use high-quality components, and each LED has its own overcurrent protection, so there is no need to worry about damage.

12. Consistent light color: No lens is added, and uniform light color is not lost to increase brightness so that uniform light color is maintained without an aperture.

13. LED does not contain the hazardous element mercury, and its disposal will not affect the environment.

When the aforementioned energy-saving methods are combined, the energy-saving impact is impressive and may save more than 60 percent of power compared to high-pressure sodium lights.

14. Low cost of maintenance: compared to conventional street lights, LED street lights have an incredibly low cost of maintenance. After comparison, it is possible to recoup all input expenses in less than six years.

However, LED street lights are not ideal, and there are still issues that need to be resolved.

1. A single LED consumes little electricity. To get high power, several parallel connections are necessary.

2. In actuality, the color rendering index of LED remains low. The color shown by LED lighting is less accurate than that of incandescent lighting. This requires analysis of the spectral distribution, which is a technological challenge.

3. There are bright patches visible. Due to faults in the manufacturing process of the white LED and mismatching with the reflecting cup or lens, the "yellow circle" issue is easily triggered.

4. Difficulty with LED lighting homogeneity The lighting of the LED is very concentrated if the secondary optical design is not implemented, hence the secondary optical design must be implemented for the light intensity distribution map to resemble a bat.

5. Compared to low-power LEDs, the light fade of high-power LED street lights is far superior. Low-power LEDs produce relatively little heat, though. The high-power LED has an issue that cannot be resolved by heat dissipation, and the brightness will be much diminished after heating, therefore the power cannot be raised. The most powerful LED street light available on the market is 300W.
