Customized 2000 Cycles Lithium Battery Street Light Head with High Luminous Flux and Wide Temperature Range for Solar Systems

Product Overview

Designed for high-power lighting scenarios like urban arterial roads, highways, and industrial parks, this high-power street light head uses high-energy-density LFP cells. Single-unit capacity can exceed 100Ah, supporting parallel expansion. Paired with high-power LED sources offering luminous flux over 10,000lm, it provides long-distance illumination and wide coverage.

Core Advantages

• High-Power Output:​ Supports continuous discharge currents of 50A-100A, with peak currents up to 200A, meeting the power demands of high-power LED lights.

• High Luminous Efficacy:​ Uses high-efficiency chips (e.g., Bridgelux, CREE, Epistar) with efficacy up to 130 lm/W, making it about three times brighter than traditional sodium lamps at the same power level.

• Wide Temperature Range:​ Optimized for low temperatures, operating reliably at -20°C, suitable for cold northern regions. Also performs stably in high temperatures up to 60°C.

Product Parameters

Application Case

Case: Industrial Park Road Lighting Project in Guangdong

An industrial park in Dongguan, Guangdong, with high electricity consumption, installed Liwei high-power street light heads (24V 150Ah battery, 200W LED) paired with 300W solar panels. The system stores solar energy by day for night-time road lighting. Over one year, it generated about 1.2kWh daily, saving roughly ¥2,000 in electricity costs annually. It provides normal lighting for up to 3 consecutive cloudy days, ensuring nighttime production safety.

Q&A

Q1: What are the configuration recommendations for high-power street light heads?

A: Recommendations: 1) Road width 8-10m: 100W LED + 100Ah battery + 200W solar panel; 2) Road width 12-15m: 200W LED + 150Ah battery + 300W solar panel; 3) Road width >15m: 300W LED + 200Ah battery + 400W solar panel.

Q2: How is the heat dissipation performance?

A: The product uses an aluminum die-casting shell and heat fins with an intelligent temperature control system that automatically reduces power if temperatures get too high, ensuring safety. Excellent heat dissipation supports long-term high-power operation.

Q3: Does it support grid-connection?

A: Yes. Equipped with a grid-tie controller, excess energy can be fed back to the grid after the battery is fully charged, generating additional revenue. Also supports off-grid operation, automatically switching during power outages to ensure uninterrupted lighting.
