The direct investigation of solar street lighting personnel is directly proportional to the visual intensity of the personnel. The actual road surface diffuses to reflect directly, as long as the surface brightness is uneven. The surface brightness of such a point, the illumination and incident angle of light, the surface reflection characteristics, and the investigation orientation function. So even at different points on the illuminated road, the brightness varies due to the location related investigators.  
The production materials of solar street light panels have a crucial impact on their service life. Generally speaking, during the 25 years of laminated tempered glass encapsulated solar panels, pet laminated assembly of solar panels takes 5 to 8 years of life, and epoxy resin encapsulated solar panels take 2-3 years of life.  
Provide a comfortable and strong visual environment for road users. The first impact of road lighting on road users at night is to ensure traffic safety. Due to the serious consequences of car speed and attacks, it is first necessary to ensure the visual task requirements of motor vehicle drivers.  
The solar street light panel is used to receive direct sunlight and collect energy attacks from sunlight, which is also an indispensable component of the solar street light system. Generally speaking, solar panels can be divided into laminated tempered glass packaging, pet laminated packaging, and drip packaging.  
The following are the basic elements that directly affect the visual stability of drivers: the brightness of objects on or near the road, and the brightness of scenery on the road; Identify the scale of objects and details; Object and set brightness contrast between them; The useful moments for investigating the brightness comparison of vehicles on the road, surface and environmental investigations, and the survey subjects; The degree of glare. Based on the above factors. Then determine the factors and requirements that affect the quality of road lighting. The foundation of setting lighting parameters is brightness, which can be seen from an object and cause visual reactions. Because the eyes that emit light on their surface receive more light, the visual sense becomes stronger. The surface illuminance is used to investigate the amount of light received per unit area of the target surface, and investigators cannot directly provide visual power.  
Regarding users, therefore, it does not directly depend on surface illuminance and shadow, but rather on brightness. The road surface illuminated only reflects the road surface conditions of light flux, and cannot reflect the state of light reflection faced by the road. Therefore, it is not a direct reflection of the quality of road lighting. Within the visual range, there are images with different brightness that directly affect the driver's visual function.  
There is a close relationship between road lighting quality and driver's visual perception, and if the company aims to improve vision, bait must be used. Therefore, the evaluation of road lighting quality starts with the fundamental factors that affect the driver's visual stability and the request to leave. Visual solidity includes two aspects: visual function and visual comfort. Visual function refers to the function of a driver seeing an object, the changes in their field of vision, and the physiological effects of vision in a normal state. A visually comfortable visual environment refers to the attack of road lighting, and the driver feels very comfortable psychologically.  
Therefore, as long as various parameters are set according to the concept of lighting brightness, the demand for excellent visual and strong sexual satisfaction is met. Since 1940, the world has been evaluating road lighting systems, brightness, and increased visibility in the 1970s. The identification of equal probability functions can be summarized as evaluation objectives in order to more objectively, comprehensively, and accurately reflect the quality of solar street lighting.
