Based on the classic modular design-our first generation LED street light, our upgraded generation improves the module design as 4 × 6 arrays. Although LEDs were deducted, but the light efficiency is much higher and much more effective based on the dual lens design, this kind of design has really achieved a high luminous efficiency, low power consumption and excellent heat dissipation characteristics. By scientific calculating, the whole lamp lighting efficiency can raise by 20%, temperature rising can be decreased by 20% and the energy saving rate can be increased by 20%.
