Rural Solar Street Lamp: How to Choose the Light Source of Street Lamp?

Solar photovoltaic panels. Common solar panels are single crystal and polycrystalline. If customers do not have special measuring instruments when purchasing, they can choose stupid methods to measure the area. The larger the area, the greater the panel power.The selection of light source is an important step in rural solar street lamps. At present, there are few special light sources for rural solar street lamps. In order to reduce the loss of limited energy, DC light source shall be selected as far as possible. Now common light sources include DC energy-saving lamp, high-frequency electrodeless lamp, low-pressure sodium lamp and LED light source.

Rural Solar Street Lamp: How to Choose the Light Source of Street Lamp? 1

Rural solar street lamp driver is a product specially developed for LED street lamp system, which is used to provide stable power supply for LED lamps. Using advanced electronic power supply technology, two output modes of high efficiency enhancement and ultra energy-saving pulse width modulation (PWM) are designed. LED lights can be turned on in high efficiency and enhanced mode when needed (when there are many blacks and many cars in the first half of the night) to provide good lighting. At other times (at night when there are few people and cars in the second half of the night), they can be output in super energy-saving mode to save battery power consumption.

Solar panels can be divided into single crystal and polycrystalline. The price of single crystal is higher than that of polycrystalline. Because customers do not have professional measuring instruments when purchasing, they advocate measuring with scale area. The larger the scale area, the larger the scale of the solar panel, which is directly proportional to the power of the solar panel. According to the lamp power and sunshine duration, the appropriate solar panel and battery need to be selected through scientific calculation.The commonly used light sources include: three primary color energy-saving lamp, high-pressure sodium lamp, low-pressure sodium lamp, led and ceramic, which can store electric energy. The super bright LED lamp is used as the light source, controlled by the intelligent charge discharge controller, and the ordinary electric lighting is used to replace the traditional street lamp, which can ensure the normal operation in cloudy and rainy weather for more than 15 daysThe system is composed of LED light source (including driver), solar panel, battery (including battery incubator), rural solar street lamp controller, street lamp pole (including foundation) and auxiliary material line. This paper analyzes and compares the light sources of rural solar street lamps. The specific type selection shall refer to the road conditions and customer requirements. It should be noted that various light sources have certain power, limitations and general standards. When selecting power, try to select the power of ordinary light source.
