What Is The Standard For Solar Street Lighting?
In recent years, with different countries support for the environmental protection industry, the development of solar street light industry is getting faster and faster. Along with the development, more and more solar street lights are on the market, but lots of problems are coming, uneven illumination and unreasonable light distribution etc.
Why? Because the industry don’t have standard. From the user's point of view, due to don’t know the technology of solar street lighting, only a brief understanding of the market's simple mainstream configuration, such as: solar panel’s watt, battery’s capacity and led chip quantity. Therefore, these unreasonable parameters can only be used as selection standard. The user's choice determines the choice of the manufacturer. Because the industry lacks standards, users do not understand the market, and many unscrupulous manufacturers seize the market loopholes and use inferior materials and accessories, thus causing confusion in the industry. So what is the standard of solar street light?
After in-depth thinking, Road Smart finally got an answer: The user did not purchase parameters, not configuration, not power, what the end uaser purchase is light. Road Smart return to the user's essential needs, study the real user’s needs, formulate a x quality standards of formulate, initiate “Rs standard", to test solar street light by total light radiation and light quality.
Total light radiation
Road Smart finds out and defines a term that can measure the luminous ability of solar street lightings: the total amount of light emitted by the solar street light every night, and the unit is represented by “lmh”.
Light type - the shape of the light on the ground
The photoelectric conversion rate is particularly scarce, so the light is very precious for solar street lightings. In order to maximize the use of light, Road Smart has been studying how to the reasonablly use light, reducing the waste of outside light. The patented lens was eventually developed, to perform secondary light distribution on the light. to make the light parallel to the road and improve light utilization.
Uniformity - The brightest and darkest difference in the value of light on road
Road Smart compare ordinary solar street lighting and Road Smart solar street lighting, get below data: ordinary street lamp 60 watt light source, center illumination 32lux, 7 meters illumination 5lux, 10 meters illumination 0lux.
Road Smart 30W intelligent solar street light, center illumination 30lux, 7 meters illumination 14lux, 10 meters illumination 7lux, 15meters illumination 3.
Through the comparison, Road Smart solar smart street lamp is superior to ordinary solar street lightings in terms of evenness. Road Smart took a lot of effort in the uniformity of the product, developed a number of patents, rationally allocated the light, solved the problems such as concentrated beam and obvious dark spots, and achieved the effect of larger irradiation area and more uniform illumination. In addition, through the data comparison, Road Smart solar smart street lamp is also significantly larger than the ordinary street lamp in the illumination area, and is highly visible at night, providing a better lighting environment for pedestrians.
Color temperature - the color of light felt by human eye
The color temperature of the light source is different, and the light color is also different. The light with low color temperature is yellowish, we call it warm colors. In terms of emotion, warm colors give people a warm feeling. In the role, the yellow light is good in fog. High color temperature light is white light, in emotion, in cold colors gives a visual sense of coldness, in effect, high color temperature white light for road lighting has an intermediate visual effect, good visibility, brighter than the low color temperature yellow light. However, if the color temperature is too high or too low, people will feel discomfort. In different environments, color temperature has different meanings in terms of emotion and function. Road Smart not only maintain the appropriate color temperature, but also have to adapt to different environments.
Ra - the extent to which the light source restores the color of the object
The higher the sign, the stronger the reduction of light, but the lower the brightness. Explicit means irrational, it will cause the poor light environment to create, and vice versa. Road Smart solar street lights is recommended to take a compromise, Ra≥70.
Glare - The dazzling intensity of light felt by human eye
Glare will cause visual fatigue, it will have a certain impact on the eyes and cause eye discomfort, glare may cause some danger when driving or outdoor sports. Therefore, no glare and anti-glare is a standard of light quality. Road Smart pursues the ultimate goal of light quality - to make the eyes more comfortable. In the development of solar street light products, it also pays attention to anti-glare and allows users to have a better light environment.
Road Smart "Rs standard" tests solar street lightings based on the total amount of light radiation and the quality of light. The development of the industry requires standards, standards to regulate the industry, the industry can move toward the direction of standardization and standardization. Road Smart in solar street lighting industry is conscientiously adhering to the "Intelligent solar led street light" for corporate mission, is committed to storing and restoring the sun, so that street lamps are increasingly close to the sunlight effect. At present, Road Smart solar street lightings has lighted more than 120 countries. In the future, Road Smart will continue its efforts to bring more light to cities, will lead the solar lighting industry to develop in the direction of smart standardization, promote global green energy development.
