Principle of street lamp holder

Created the integrated design of radiator and lamp shell. The LED is directly connected with the shell, and the cooling wing of the shell convectively dissipates heat with the air, which fully guarantees the service life of the LED street lamp of 50,000 hours. Calculated by working 12 hours per day, its service life is also over 10 years, and the maintenance cost is extremely low;

The cavity of single elliptical reflector is designed with a spherical surface, and the light emitted by led is controlled within the required range, which improves the uniformity of light emission effect and the utilization rate of light energy, and highlights the energy-saving advantages of LED street lamps. Compared with the traditional sodium lamp, it can save more than 60% electricity;
