l GaN/Si Yellow LED: Utilizes captured solar energy to the maximum extent with its industry-leading luminous efficacy of 200 lm/W. Stable lighting output is maintained even under low-light conditions.

l Comprehensive Benefits: Ultra-high energy conversion efficiency significantly reduces overall energy consumption, conserving resources while effectively lowering long-term operational and maintenance costs, perfectly aligning with global green energy trends.

2. Scientific Light Distribution, Precise Coverage

The product's scientifically optimized lighting design is a major highlight:

l Optimal Mounting Height: The best installation height for the streetlight is determined through precise calculation.

l Triangular Illumination Layout: Employs a unique triangular illumination zone design, positioning the light source at the apex to ensure uniform and ample light coverage on both sides of the road.

l Broad Application Scenarios: When installed on a 4-meter pole, it achieves a horizontal illumination range of 14 meters. Extending the pole to 8 meters expands the lighting angle to 120°, easily meeting diverse needs such as urban thoroughfares, rural roads, and public squares.

3. Yellow Light Advantages, Eco-Friendliness

GaN/Si yellow LEDs not only meet high-brightness requirements but also prioritize visual comfort and ecological harmony:

l Visual Comfort: Compared to traditional white LEDs, yellow light emits a softer hue, effectively reducing visual fatigue and glare interference. It is particularly suitable for complex weather conditions like rain, fog, or dust, enhancing nighttime visibility.

l Ecological Friendliness: The lower intensity of yellow light significantly minimizes adverse effects on surrounding flora and fauna. It helps protect insect activity patterns and the circadian rhythms of nocturnal species, fostering a more harmonious lighting ecosystem in both urban and rural areas.

4. Durability and Low Maintenance

l Advantages of GaN/Si Material: Ensures highly efficient light emission while significantly reducing heat generation, effectively preventing lumen degradation caused by high temperatures.

l Stable and Long-Lasting: Low heat characteristics guarantee stable performance during prolonged operation, substantially extending service life.

l Structural Optimization: The streamlined structural design simplifies installation and maintenance procedures, reducing replacement frequency and subsequent upkeep costs. This balance of advanced technology and economic viability paves the way for future large-scale applications.

5. Green, Low-Carbon, Self-Sufficient Energy

l Daytime Energy Storage: During the day, the streetlight efficiently collects solar energy through vertical photovoltaic tubes and converts and stores it as electrical energy.

l Nighttime Illumination: At night, ultra-efficient LEDs utilize the stored energy for illumination, achieving fully clean energy-powered lighting.

l Environmental Benefits: This design significantly reduces reliance on the municipal power grid, effectively lowering carbon emissions, aiding cities in achieving low-carbon goals, and responding to global sustainable development strategies.

Future Outlook:
