The difference between
solar street light and conventional street lights is that the LED light source adopts low-voltage DC power supply, high-efficiency white light synthesized by GaN-based power blue LED and yellow, with high efficiency, quietness, energy saving, environmental protection, long life, fast response speed, and color rendering index. Advanced unique advantages, can be widely used in doors. The outer cover can be made and can withstand high temperature up to 135 degrees and low temperature up to -45 degrees. Advantages 1. Solar street light's own characteristics - unidirectional light, no light diffusion, to ensure light compliance. 2. The solar street light has a unique secondary optical design, which irradiates the light of the solar street light to the area that needs to be illuminated. It also further improves the lighting efficiency to achieve the goal of energy saving. 3. The LED has reached 111-130lm/W, and there is a lot of room for growth, with a theoretical value of 361lm/W. The luminous efficiency of high-pressure sodium lamps only increases with the increase of power. Therefore, in terms of overall light efficiency, solar street light is stronger than high-pressure sodium lamps; The light efficiency is higher than that of LED lights). 4. The light color rendering of solar street light is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of solar street light is above 75. Considering from the perspective of visual physiology, it achieves uniform brightness. The uniform illuminance can be more than 20% lower than that of high pressure sodium lamps. 5. The light decay is small, the light decay in one year is less than 3%, and it still meets the requirements after 10 years. However, the high pressure sodium light decays greatly, and it has dropped by more than 30% in about a year. Therefore, solar street light has a high efficiency rate The plan can be lower than the high pressure sodium lamp. 6. The solar street light has an automatic control energy-saving device, which can realize the maximum possible low power under the environment where lighting needs to meet different periods of time and save electricity. It can realize computer dimming, time-segment control, light control, temperature control, active inspection and other humanized functions. 7. Long service life: It can be used for more than 50,000 hours and provides three-year quality assurance. The disadvantage is that the life of the power supply cannot be guaranteed. 8. High luminous efficiency: Adopt chips of ≥100LM or more, which can save energy by more than 75% compared to traditional high-pressure sodium lamps. 9. Easy installation: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp shell. 10. Excellent heat dissipation control: The temperature is controlled below 45 degrees in summer, and passive heat dissipation methods are adopted, so the heat dissipation protection in summer is insufficient. 11. Reliable quality: The circuit power supply adopts high-quality components, and each LED has a separate overcurrent protection, so there is no need to worry about damage. 12. Uniform light color: no lens is added, and the uniform light color is not sacrificed to improve the brightness, so as to ensure the uniform light color without aperture. 13. LED does not contain harmful metal mercury, which will not cause harm to the environment when it is scrapped. The energy-saving results based on the above principles are obvious, replacing high-pressure sodium lamps can save more than 60% of electricity. Low maintenance cost: Compared with traditional street lights, the maintenance cost of solar street light is extremely low. After comparison, the price of solar street light can recover all the investment costs in less than 6 years. [The above content is organized and released for you by solar street light manufacturers]
