40 Watt Solar Street Light

40 watt solar street light is a green energy solution designed specifically for outdoor lighting, integrating efficient solar panels, intelligent controllers, and long-life lithium batteries to achieve all-weather lighting without the need for an external power source. The product adopts IP66 waterproof design and is suitable for various scenarios such as roads, courtyards, parks, parking lots, etc., meeting the international market's demand for energy conservation, environmental protection, and reliability.

Application scenarios of 40 Watt Solar Street Light

 

Road lighting

Township roads: 6-meter lamp posts cover 8-10 meter wide roads, with an average illuminance of ≥ 31lux (at a height of 8 meters).
Highway: Intelligent dimming mode, automatically adjusts brightness according to traffic flow to ensure driving safety.

Courtyard and Park

Villa courtyard: optional warm light color temperature (2700K), combined with landscape design, creates a warm atmosphere.
Scenic trail: IP66 waterproof design, suitable for humid environments, low maintenance cost.

Industry and Commerce

Parking lot: Human body induction mode, fully illuminated when people come (40W), reduced power when people walk (10W), energy-saving by 75%.
Industrial park: supports multi lamp networking, unified management through APP, and reduces operation and maintenance costs.

Installation process

1. Foundation construction
Excavation of foundation pit: excavate the foundation pit according to the design size, lay a 100mm thick gravel cushion layer at the bottom, compact and level it.
Anchor cage fixation: Place the anchor cage vertically into the foundation pit, calibrate it with a level (horizontal deviation ≤ 2mm/m), raise the flange surface 50mm above the ground, and reinforce it with steel bars around (4 pieces of Φ 12mm, surrounding the anchor cage).
Concrete pouring: C30 concrete is used for pouring, compacted by vibration, covered and cured for 48 hours (when the temperature is ≥ 15 ℃), and rolling is prohibited during the curing period.
2. Lamp Pole Assembly
Pre installation of components:
Apply anti-corrosion adhesive to the welding joint between the lamp arm and the lamp post, install LED lamps (fixed with 4 M8 bolts, torque 30N · m), and install waterproof sealing rings at the connection.
The photovoltaic panel is fixed on the top bracket of the lamp post, adjusted to the local latitude+15 ° (for example, adjusted to 45 ° in the 30 ° north latitude area), fastened with stainless steel bolts (M6 × 30mm), and the cable is led out through the tube inside the lamp post.
Overall lifting:
The crane hook is fixed in the middle of the lamp post, and the steel wire rope is wrapped around the protective pad. Slowly lift it above the foot cage and align it with the flange hole position (4 people cooperate to stabilize it).
Pre tighten 4 anchor bolts (alternate diagonal tightening), calibrate the verticality of the lamp post using a spirit level (deviation ≤ 0.5 °), and apply a final torque of 80N · m. Install spring washers to prevent loosening.
3. Circuit connection
Wiring sequence (power-off operation):
① Lithium battery: Place a 12V 30Ah lithium iron phosphate battery into the battery box at the bottom of the lamp post, with the positive pole connected to the controller "BAT+" and the negative pole connected to "BAT -". Cover the cable with a fireproof corrugated tube, and wrap the interface with waterproof tape for 3 layers.
② Photovoltaic panel: The positive and negative poles of the 90W monocrystalline silicon panel are connected to the controller "PV+" and "PV -", using MC4 waterproof connectors, and the connection is protected against reverse connection (with built-in diodes in the controller).
③ LED lamp: The positive pole of the lamp is connected to the controller "LOAD+", and the negative pole is connected to "LOAD -". A 10cm redundant cable is reserved to avoid wire clamping when threading into the lamp post.
Controller installation: Fix the MPPT controller at the maintenance port in the middle of the lamp post (with a height of 1.8 meters for easy debugging), and seal it with silicone around to ensure IP67 protection.
4. System Debugging
Light control test: If the photovoltaic panel is obstructed, the lamp should automatically light up within 10 seconds; Remove the obstruction and automatically turn off within 5 minutes (default threshold of 10lux).
Time control setting: Set the "full power 6 hours+energy-saving mode 6 hours" through the controller button. The actual measurement shows that it is fully on at 6 pm (40W), reduced to 20W at 12 am, and turned off at 6 am.
Battery level detection: The multimeter measures the voltage of the lithium battery. After charging for 4 hours on a sunny day, the voltage is ≥ 13.2V, and after 3 consecutive rainy days, the voltage is ≥ 11.5V (before triggering the undervoltage protection).
Waterproof review: Spray test lamp body joints and wiring ports, no water leakage within 30 minutes

Maintenance Guide

1. Daily maintenance (monthly)
Cleaning and maintenance: Wipe the photovoltaic panel with a soft cloth (alcohol is prohibited) to remove dust from the surface of the lamp body; Use compressed air to blow the heat dissipation holes of the controller (to prevent dust accumulation).
Bolt tightening: Check the anchor bolts of the lamp post (torque retest 80N · m) and the photovoltaic panel bracket bolts (M6 bolt torque 15N · m), and reinforce them in a timely manner if any looseness is found.
2. Deep maintenance (quarterly)
Battery testing: Use a multimeter to measure the internal resistance of a lithium battery (new battery ≤ 50m Ω). When the capacity is below 80%, it is recommended to activate charging (use a dedicated charger, current ≤ 10A).
Controller calibration: Reset the light control threshold (recommended to adjust to 8lux in winter and 12lux in summer), update the time control program (adjust the lighting period according to the duration of day and night).
3. Annual maintenance (starting from the 12th month)
Anti corrosion treatment: Spray outdoor paint on the surface of the lamp post (key welding points, flange interfaces), and increase the thickness of the galvanized layer (≥ 85 μ m) in salt spray environments.
Component replacement: It is recommended to replace lithium batteries that have been used for more than 5 years (cycle life>3000 times), and synchronously check the LED light decay (replace the chip when the illumination drops by ≥ 30%).
