green lighting, lighting up the future In response to the global call for energy conservation and emission reduction, the Czech Republic has successfully installed 8-meter-high, 60 watt solar street lights in multiple cities and rural areas, promoting sustainable energy applications and smart city construction.    Project highlights 1. Efficient and energy-saving Using a 60 watt high brightness LED light source, combined with a large capacity lithium battery and high-efficiency monocrystalline silicon solar panel, the daily sunshine of 4-6 hours can meet all night lighting needs, completely bidding farewell to traditional power grid dependence.    2. Intelligent control Built in light sensing and human body sensing system, automatically adjusts brightness (30% at night, 100% when people and cars pass by), saves energy while extending range, and can still work stably for 5-7 days on rainy days.    3. Environmentally friendly and durable The entire system has zero carbon emissions, and the lamp posts are made of hot-dip galvanized anti-corrosion steel, suitable for the extreme climate of Czech Republic from -30 ℃ to 40 ℃, with a lifespan of over 10 years.    4. Widely applicable The 8-meter pole design covers a lighting radius of 15-20 meters, perfectly adapting to scenes such as roads, squares, parks, etc. It has covered areas such as the suburbs of Prague and rural Moravia.    social benefit -Annual emission reduction of over 200 tons of carbon dioxide -Reduce municipal electricity bills by 30% -Improving nighttime safety and residents' quality of life Czech Republic practices environmental protection with technology, setting a benchmark for Europe's green energy transformation!

LED street light (Light Emitting Diode Street Light) is a modern road lighting device that uses LED light sources. Compared with traditional high-pressure sodium lamps (HPS), metal halide lamps (MH), etc., it has the advantages of high efficiency, energy saving, long life, and environmental protection. It has become the mainstream choice for outdoor lighting in municipal, highway, park and other areas around the world. 1. Core characteristics of LED street lights (1) Efficient and energy-saving High luminous efficiency: up to 100-200 lm/W (traditional sodium lamps only have about 80-100 lm/W), with lower power consumption under the same brightness. Intelligent dimming: supports PWM dimming, MPPT efficient charging, timed dimming, radar sensing, etc., further reducing energy consumption. (2) Ultra long lifespan LED chip lifespan: 50000-100000 hours (approximately 10-15 years), much higher than the 10000-20000 hours of sodium lamps. Low maintenance cost: LED light sources are not easily damaged, reducing replacement frequency. (3) Environmental protection and safety Mercury free: Free from heavy metals and compliant with RoHS environmental standards. Low UV radiation: reduces light pollution and has low attraction to insects. (4) High Color Rendering Efficiency (CRI) CRI ≥ 70 (some high-end products can reach 80+), close to natural light, improving nighttime road recognition. (5) Seismic and impact resistance Solid state light source design, no filament or glass parts, suitable for harsh environment (such as typhoon, rainstorm area). 5. Mainstream LED street light types in the market (1) Classified by installation method Single arm street lamp (conventional road) Dual arm street lamp (wide road) High pole lights (plaza, highway service area, 15-40 meters) (2) Classified by power supply method Commercial LED street lights (mainstream, stable power supply) Solar powered LED street lights (off grid application, paired with photovoltaic panels and batteries) Wind solar complementary street light (wind and solar hybrid power supply) Complementary street lights for urban electricity supply (3) Classified by intelligent functions Intelligent dimming street light (automatically adjusts brightness according to traffic flow) IoT street lights (remote monitoring, fault alarm) 5G smart street lights (integrated with 5G base stations and environmental monitoring) 6. Key parameters for selecting LED street lights Luminous flux (lm): brightness, such as 30000lm ≈ 200W LED street light Color temperature (K): Warm light (2500-3000L) Warm white (3500K-4500K) or regular white (5000K-6500K) Protection level (IP): IP65 (dustproof and waterproof) or above Power factor (PF): ≥ 0.95 (high-efficiency power supply) Warranty period: usually 3-5 years (5-10 years for high-end brands) Summary: LED street lights, with their advantages of energy saving, long lifespan, and high brightness, have gradually replaced traditional street lights and played an important role in the construction of smart cities.
