Adjustable Module Angle Integrated Solar LED Street Light

Adjustable Module Angle Integrated Solar LED Street Light
The Adjustable Module Angle Integrated Solar LED Street Light is designed specifically for outdoor lighting projects in regions with varying latitudes and installation conditions. Unlike traditional fixed-angle solar lights, this product allows for manual adjustment of the solar panel module angle according to the solar elevation angle at the installation site. This ensures the best light incidence angle throughout the seasons, improving photoelectric conversion efficiency. The product features an integrated design, with the solar panel, LED light source, lithium iron phosphate battery, and MPPT controller all integrated into the same light body, requiring no external cables and simplifying installation. The lithium iron phosphate battery has excellent high and low-temperature performance, ensuring stable operation in both hot summers and cold winters. It is equipped with an SRNE brand MPPT controller, offering higher charging efficiency than ordinary PWM controllers.

Materials and Structure
The lamp body is made of die-cast aluminum, which has good thermal conductivity, effectively transferring the LED heat to the lamp surface for dissipation. The single-crystal silicon solar panel has a higher conversion efficiency than polycrystalline silicon, with a service life of 5 years. The lithium iron phosphate battery has a long cycle life of 8 years and a wide operating temperature range. The LED light source uses 3030 chips with 50 beads per module, with the number of beads increasing with power: 40W uses 2 modules (100 beads), 50W uses 3 modules (150 beads), 60W uses 4 modules (200 beads), and 70W uses 5 modules (250 beads). The light efficiency is ≥150lm/W, with a light distribution angle of 70×145°, providing a wide illumination range. The color rendering index (Ra) is ≥70, and the color temperature can range from 3000K to 6000K. The controller is of the SRNE MPPT type, and its power and current are matched to the LED power. The protection rating is IP65, and the operating temperature is from -20°C to 60°C.

Surface Treatment
The surface of the lamp body is treated with electrostatic powder coating. The color can be selected from matte black or silver-gray, with strong corrosion resistance. The surface is sandblasted and cleaned before coating to ensure strong adhesion.
