Do you know that solar street lights are made up of those parts?
The controller is microcomputer intelligent control. The photovoltaic controller has overcharge and over discharge functions, output short circuit protection, light control and time control functions, and is tested by the indicators of the Industrial Product Quality Supervision and Inspection Center of the Ministry of Information Industry. It has protection functions such as constant current, soft start, half power, reverse connection, lightning protection and temperature compensation. Marked with charging, over discharge, load, display indicator, cable with core wire for national standard 4.0 mm2 wire
The battery buried box is a special buried box for the solar street lamp. It has waterproof and cold protection measures, which can effectively resist the damage of the rainwater and low temperature to the battery. It is the battery operating in the normal range.
The battery is sealed and maintenance-free lead-acid battery 120AH, which is installed in the ground. It has strong cycle endurance and long service life. The quality guarantee period is 3 years and the actual service life is more than 8 years. Self-discharge is small and charging efficiency is high. The internal resistance and self-discharge are small, and the current discharge characteristics are good. The temperature range is wide, between -30 and 45 degrees. Environmental protection, sealing technology is safe and reliable.
The solar street light pole technology requires that the cone pole be 6 meters high, the arm length is 1.3-1.35 meters, and the lamp head is 6 meters above the ground. The main rod is made of high-quality steel pipe, the welding rod is smooth, neat and burr-free, hot-dip galvanized and anti-corrosive, and the surface is sprayed. The life of the pole is 20-25 years.
The shell is made of heat-dissipating integrated aluminum lamp housing, which has powerful heat dissipation, low heat consumption and low light decay: aluminum-based PCB board welding process, light decay is less than 10% in one year, no heat sink is required for 5 mm small particles, room temperature Working 10H, heat sink surface and interface temperature rise ≤ 15 °C. Led light source operating voltage range of DC11V-14V can be used normally, in the range of -25 ° C - 50 ° C can be used normally.
The LED light source adopts three generations of LED cold light source, and the efficiency can reach more than 90% compared with the incandescent lamp. At the same brightness, the power consumption is only 1/10 of that of an ordinary incandescent lamp, 1/3 of a fluorescent tube, and 1/2 of a low-voltage energy-saving lamp. The effective service life is 5,500 hours. Easy to install, can carry out any power combination. Current limiting protection: IC multi-level current limiting protection is adopted, which has high reliability.
The transparent cover is made of anti-aging EVA resin and TDT composite film with excellent weather resistance. The anodic lead frame has high mechanical strength and is resistant to wind, cockroaches and corrosion. It can be used in all kinds of complicated and harsh weather. The output terminals are sealed and waterproof, high reliability and multi-function junction box. Install bypass diodes to effectively prevent hot spot effects and line protection, and easy wiring.
Solar panel power generation efficiency of 15.5%, stable performance, life expectancy of up to 30 years of monocrystalline silicon solar panels, in line with international standards. It adopts imported high-efficiency solar cells and adopts high-strength, high-low iron ultra-white tempered glass to reduce sunlight reflection.
