Problems solved by technology

In recent years, there have been technologies that use electric field force to sweep dust away from the substrate, but whether it is direct current or asymmetrical high-voltage alternating current, the voltage requirements are relatively large, basically above 800V, which limits its application scenarios

Abstract

The invention discloses electrostatic dust-removing glass, a manufacturing method thereof, an electrostatic dust-removing lens and camera equipment. The electrostatic dust-removing glass comprises a positive electrode, a negative electrode, a plurality of positive electrode wires and a plurality of negative electrode wires. The positive electrode and the negative electrode are parallelly arrangedon the two sides of the glass; the multiple positive electrode wires are arranged on the surface of the glass and connected to the positive electrode, and are perpendicular to the positive electrode;the multiple negative electrode wires and the positive electrode wires are alternately arranged on the surface of the glass, and the negative electrode wires are connected to the negative electrode, and are perpendicular to the negative electrode; and the spaces between the positive electrode wires and the negative electrode wires are 500-1000 [mu]m. The electrostatic dust-removing glass can achieve the very high dust-removing ability only through the relative small voltage, the practicability of the electrostatic dust-removing glass can be greatly improved, and the application range of the electrostatic dust-removing glass can be greatly enlarged.

Description

technical field [0001] The invention relates to the technical field of electrostatic dust removal for glass, in particular to an electrostatic dust removal glass and a manufacturing method thereof, an electrostatic dust removal lens and an imaging device. Background technique [0002] Public places such as roads and residential areas in cities are covered with various surveillance cameras used for traffic monitoring and security monitoring. Surveillance cameras are exposed to the external environment for a long time. Dust and smog pollution in the city is serious, and it is easy to accumulate dust , thereby affecting the visibility of the lens and reducing the monitoring effect. It is time-consuming and labor-intensive to manually clean these lenses one by one, which will greatly increase the work cost. Due to factors such as aesthetics and convenience for shooting, most surveillance cameras are placed in places that are difficult for people to reach, so pollutants such as ...
