The design of solar street light / courtyard light absorbs energy from the universe, and combines it with a high efficiency solar panel, LEDs and Lithium battery. It adopts advantage techniques such as a micro-controller and combines it with an integrated design to achieve multiple features such as low power consumption but high brightness, long lifespan and maintenance free. It is also equipped with waterproof function and great thermal dissipation. The intelligent control can be reprogrammed from the ground via infrared signal before and after installation. It is one of our great innovation patented products.
