Single Arm and Double Arm For diffferent Projects Choice:
The hot-dip galvanizing process for light poles involves subjecting the base material (typically Q235 steel) to degreasing, acid washing, water rinsing, and pre-treatment with a flux. The material is then immersed in molten zinc at 440–460°C, where the steel surface undergoes a metallurgical reaction with the zinc. This forms a dense, highly adhesive composite coating consisting of a zinc-iron alloy layer and a pure zinc layer. The core advantage of this process lies in the coating's robust bonding to the substrate, which resists peeling and enables long-term corrosion protection through sacrificial anodic protection. Even if the coating is locally damaged, the zinc layer oxidizes and corrodes first, shielding the underlying steel from rust. The finished galvanized layer on lamp poles typically exceeds 85μm in thickness, delivering outstanding outdoor corrosion resistance. It withstands harsh environments such as coastal areas, saline-alkali conditions, and high fog exposure, significantly extending the lamp pole's service life to over 20 years.
Solar battery: Gel/lead-acid type, optional lithium iron phosphate/ternary lithium battery:
The depth of discharge (DOD) of lithium batteries commonly used in solar street lights (primarily lithium iron phosphate) is directly correlated with cycle life: the deeper the discharge, the shorter the battery's cycle life. Under conventional conditions, maintaining a discharge depth between 70%–80% can achieve a cycle life of 2,000–3,000 cycles for lithium iron phosphate batteries. Reducing the discharge depth to 50% extends cycle life to over 4,000 cycles.
The controller in solar streetlight systems optimizes discharge strategies to prevent over-discharge (DOD ≥ 90%), thereby avoiding plate polarization and accelerated capacity degradation. This ensures stable battery operation during outdoor day-night charge-discharge cycles, aligning with the 5–8-year service life of the streetlights.
Solar Controller: MPPT/PWM modes optional.(hybrid type available for hybrid solar street lights)
The core features of the solar hybrid controller are intelligent switching, energy-saving priority, and stable power supply. It prioritizes using electricity generated by photovoltaic panels to power streetlights. When solar energy storage is insufficient (during consecutive rainy days), it automatically switches to grid power for supplemental supply, ensuring streetlights remain stably illuminated around the clock. Equipped with multiple protection functions including overcharge, over-discharge, overload, and short-circuit protection, it effectively extends the service life of batteries and light sources. Supports manual/automatic mode switching to adapt to diverse application scenarios. Precisely controls charging and discharging parameters to reduce grid power usage, lowering electricity costs while simplifying system wiring and maintenance. Ideal for areas with unstable sunlight or high endurance requirements.

FAQ
Q: How does the light know when to turn on and turn off?
A: Lighting fixtures employ multiple mechanisms for on/off control, including the following common methods: Manual Control: Operate fixtures by manually switching or pressing buttons. These switches or buttons control lighting by physically connecting or disconnecting circuits. Motion Sensors: Fixtures equipped with motion sensors use infrared or ultrasonic technology to detect movement or changes in the surrounding environment. When motion is detected, the sensor triggers the lights to turn on. If no movement is detected within a set timeframe, the lights automatically turn off. Light-Sensitive Components: Some fixtures incorporate light-sensitive components (also known as photosensors). These sensors detect ambient light intensity, automatically turning lights on at dusk and off at dawn. This technology is widely used in outdoor lighting, streetlights, and security lighting. Timer Control: Lights can be connected to timers for scheduled on/off operation. This feature is suitable for locations requiring fixed lighting patterns, such as commercial buildings or outdoor display lighting.
