Abstract

The invention discloses a solar sodium lamp rectifier. The solar sodium lamp rectifier comprises a storage battery charger, a direct-current storage battery, a DC / DC boosting module and a DC / AC inverter module which are connected in sequence, wherein the output end of the DC / AC inverter module is connected with a low pressure sodium lamp. The low pressure sodium lamp rectifier also comprises a driving controller for controlling the DC / DC boosting module and the DC / AC inverter module. According to the solar sodium lamp rectifier disclosed by the invention, the circuit works stably, each kind of protection work is reliable, constant power control is realized basically, the starting circuit can be started reliably for multiple times, and the structure is simple.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a solar sodium lamp rectifier. Background technique [0002] Solar energy as green energy will be an energy-saving project vigorously promoted by the country, and low-pressure sodium lamp is the best light source for energy-saving renovation of lighting projects and solar lighting systems. It has high luminous efficiency of 200lm / W and long life, high visual resolution and good contrast. , the advantages of not being affected by the ambient temperature are widely used in roads, viaducts, tunnels and intersections and other places with high visibility and low color rendering requirements. The low-pressure sodium lamp also has no glare, and will not cause premature damage to the optical system of the lamp due to the erosion of the ambient gas. [0003] In the past, low-voltage sodium lamps used traditional auto-coupling magnetic flux leakage inductance ballasts. Due to their lar...
