Optical devices and their applications

Abstract

The present invention provides an optical device and its application. The optical device includes at least one lens, a lens barrel, at least one heating element and at least two conductive elements, wherein the lens is mounted on the lens barrel, and the heating The element is arranged on the lens, wherein the heating element has at least two terminals, wherein the at least two conductive elements are respectively fixed at positions electrically connected with the corresponding terminals, wherein the conductive element has a A conductive contact surface, wherein the conductive contact surface is electrically connected to the terminal of the heating element in a surface contact manner, wherein the at least two conductive elements are used to connect to a power supply device so that the power supply device provides electricity to the heating element to heat the lens, and avoid the problem of uneven heating of the heating element caused by the connection between the heating element and the wire due to welding or the like.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical device and its application. Background technique [0002] With the development of science and technology, optical devices such as vehicle lenses, optical lenses, optical lampshades, etc. are more and more used in people's daily life. For example, in order to provide the comfort and safety of car driving, vehicle lenses are widely used in the fields of front view, rear view, surround view, interior view, and side view of cars. At the same time, with the continuous development of automobile technology, the number and performance of the vehicle lens required in the car have been greatly improved, and the requirements for the weather resistance of the vehicle lens are also more stringent. [0003] When the vehicle is driving in continuous rainy, frosty or alternately cold and hot environments, the inner and outer surfaces of the near-object side lens of the vehicle lens are prone to...

AI Technical Summary

Problems solved by technology

However, the heating element inside the existing vehicle-mounted lens mainly uses tin welding to connect the wires, and the welding point area of ​​the heating element is relatively large. The resistance of the heating element is different, so that the overall heating of the heating element is not uniform enough, resulting in uneven heating of the lens, which affects the optical performance of the vehicle lens

[0005] In general, the heating element usually uses a heating wire. Due to the extremely small line width of the wire, in the manufacturing process of the vehicle lens, the welding surface between the wire and the heating wire is extremely small, and the welding between the wire and the heating wire Difficulty, low yield, relatively high cost
