We all know that the development trend of solar street lights is very strong nowadays. Many places have replaced traditional street lights with solar street lights, partly because they are cost-effective and convenient, and partly because they are energy-saving and environmentally friendly. So, how should we choose the appropriate light source for solar street lights? Below, the editor from Century Sunshine Lighting will introduce this topic.
Solar photovoltaic panels come in monocrystalline and polycrystalline types. If customers do not have specialized measuring equipment when purchasing, a simple method can be used: measure the area, as the larger the area, the greater the power of the solar panel.
Choosing a light source is an important step for solar street lights. Currently, there are few light sources specifically designed for solar street lights. To minimize the loss of limited energy, it is advisable to choose direct current (DC) light sources. Common light sources include DC energy-saving lamps, high-frequency induction lamps, low-pressure sodium lamps, and LED sources.
The solar street light driver is specifically developed for the LED lighting system to provide a stable power supply for LED fixtures. It utilizes advanced electronic power technology and features two output modes: high-efficiency enhancement and ultra-energy-saving pulse width modulation (PWM). It can light up the LED fixtures in a high-efficiency mode during peak demand times (like late at night when there are more people and vehicles) to provide adequate illumination, while during less busy times (like after midnight) it outputs in ultra-energy-saving mode, conserving the battery’s energy consumption.
Solar panels are categorized into monocrystalline and polycrystalline, with monocrystalline panels being more expensive than polycrystalline ones. Since customers may not have professional measuring instruments when purchasing, it is recommended to use the area size for measurement. The larger the area, the larger the size of the solar panel, which is proportional to the power of the solar panel. The appropriate solar panel and battery should be chosen based on the lamp head power and sunlight duration, which must be calculated scientifically to obtain accurate parameters.
Common types of light sources include: triphosphor energy-saving lamps, high-pressure sodium lamps, low-pressure sodium lamps, LEDs, and ceramics, which store electrical energy. Ultra-bright LED fixtures are used as the light source and controlled by an intelligent charge-discharge controller, replacing traditional utility power lighting for street lights, ensuring normal operation for over 15 days during rainy weather.
The system composition includes LED light sources (with drivers), solar panels, batteries (including insulation boxes), solar street light controllers, lamp poles (including foundations), and auxiliary wiring materials. Here, we analyze and compare the commonly used light sources for solar lighting fixtures. When selecting, reference should be made to road conditions and customer requirements. It is worth noting that various light sources have specific power limits and commonly used specifications. When choosing power, it is advisable to select from the commonly used light source power ratings.
The above information on how to choose the appropriate light source for solar street lights is shared here. The principle for selecting solar street light sources is to choose those suitable for environmental requirements, with high luminous efficacy and long lifespan. Additionally, to improve the efficiency of solar power usage, it is advisable to select direct current input light sources to avoid power loss caused by the introduction of inverters.
