Solar street lights are directly proportional to the intensity of the person's vision. The actual pavement surface diffuses to directly reflect, as long as the brightness of the surface is uneven. The surface brightness of such a point, the angle of incidence of point illumination and light, the reflection characteristics of the surface and the investigation azimuth function. So even if different points on the illuminated road are located, the brightness is different because of the location associated with the investigator.
Solar street light panels are produced from materials that have a vital impact on their service life, generally speaking, laminated tempered glass encapsulated solar panels for 25 years, solar panels for pet laminated assembly for 5 to 8 years of life, epoxy resin encapsulated solar panels for 2-3 years of life.
Provide a comfortable, intense visual environment for road users. For road users at night, the first impact of road lighting is to ensure traffic safety. Because of the serious consequences of the problem of car speed, attack, it is necessary first of all to ensure the needs of the visual task of the motor vehicle driver.
The solar street light panel is used to receive the solar street light directly irradiated by the sun and collect the energy attack of the sun, which is also an indispensable part of the solar street light system. Generally speaking, solar panels can be divided into laminated tempered glass packaging, pet laminated packaging, and epoxy packaging.
The following aspects evaluate the relationship between the driver's vision and the road lighting parameters, and the basic elements that directly affect the driver's vision are as follows: the brightness of the road or objects near the road, and the brightness of the scenery on the road; identify the scale of objects and details; objects and settings for brightness contrast between them; Brightness of the car on the road contrasts surfaces and environmental surveys, the useful moments of the survey subjects; degree of glare. According to the above factors. The influencing factors and requirements for road lighting quality are then determined. Set the lighting parameters at the base, the brightness, an object can be seen, causing a visual reaction. Because its surface glows with the eyes, the more light, the stronger the sense of vision. The illumination of the surface to investigate the amount of received light per unit area of the target surface, the investigator cannot directly give visual power.
With regard to the user, therefore, there is no direct dependence on the surface illuminance of light and shadow, and depends on the brightness. The illuminated surface of the road only reflects the pavement condition of the luminous flux, and does not reflect the state of the road facing light reflection, so it is not a direct reflection of the quality of the road lighting. Within the visual range, there are pictures of different brightness that directly affect the driver's visual function.
There is a close relationship between the quality of road lighting and the driver's sexual vision, and if the company improves the vision, it must be baited. Therefore, the evaluation of the quality of road lighting begins with the solid fundamental factors that affect the driver's vision and the request to leave. Visual solidity encompasses two aspects: visual function and visual comfort. Visual function refers to the function of the driver to see the object, the change of its visual field, and the visual physiological effect in a normal state. The visual environment of visual comfort refers to the attack of road lighting, and the driver feels psychologically comfortable.
Therefore, as long as various parameters are set according to the concept of illumination brightness, talent requires excellent visual intensity of sexual satisfaction. Since 1940, the world began to evaluate the road lighting system, brightness and increased visibility in the 70s, identifying such probability functions as the evaluation objectives, in order to more objectively, more completely and accurately reflect the quality of solar street lighting road lighting.
