How to determine whether the lighting efficiency of solar street lights has reached the optimal state?
Jun 13, 2024
1. Average illuminance and uniformity
Good solar street lights should be able to evenly illuminate the entire road, rather than just having high brightness below the street lights. For example, when using all in one solar street lights, attention can be paid to whether their lighting coverage is wide and uniform. In addition to brightness, the uniform distribution of light is also important. The latest national standard requires uniformity between 0.3-0.4, and excellent solar street light products should be able to meet or exceed this standard. For example, our company's product Solar Street Light Sensor All In One 100w.
2. Number of support for cloudy and rainy days
The support number of solar street lights on cloudy and rainy days is an important indicator for judging their performance. The design and configuration of all in one solar street lights and all in two solar street lights should ensure that they can maintain a certain lighting time even in continuous cloudy and rainy days.
3. Light efficiency (lm/w)
Light efficiency refers to the ratio of the luminous flux emitted by a light source to the power consumed. Efficient and energy-saving solar street light products, such as all in one solar street lights using LED light sources, usually have high light efficiency, with a luminous power conversion of nearly 98% or more, saving 60% -80% more energy than traditional lighting fixtures.
4. Product parameters and certification
By examining the product parameters of solar street lights, such as power, luminous flux, beam angle, etc., one can understand their performance characteristics. At the same time, pay attention to whether the product has obtained relevant certifications, such as CE, ROHS, etc. These certifications are important guarantees of product quality. Our company's product Auto Clean Waterproof Solar Led Lights All In One 70W has passed CE certification and ROHS certification.
