Problems solved by technology
[0004] However, since the electric heating wire needs to be embedded in the lens to keep it fixed, changing the original structure of the corresponding lens not only increases the difficulty of the overall manufacturing process of the lens and increases the cost, but also destroys the strength of the corresponding lens, making The lens is easy to break especially after heating up, the image quality becomes poor, and it cannot be repaired
Moreover, the electric heating wire itself also has problems such as low heating efficiency, poor heating uniformity, and complicated installation.
And directly adopt the structure of heating material embedded in the lens, there will be problems such as the overall stability of the lens is weak, and the weather resistance is poor in bad weather.

The invention provides a heating device, a lens with the heating device, a lens comprising the lens and a method for preparing the lens comprising the heating device. The lens comprises a lens body and a heating device. The lens body is provided with a first surface and a second surface opposite to each other and an edge connecting the first surface and the second surface; the heating device is arranged on the edge of the lens body and used for transferring heat to the lens body after being powered, and the heating device is constructed to be a ceramic heating ring or a polyimide PI heating film internally provided with a heating element. The lens with the heating device and the lens comprising the lens can effectively improve the weather resistance of the camera module.
Description
technical field [0001] The present application relates to the technical field of optical equipment, and more particularly, to a heating device for a lens, a lens with the heating device, a lens including the lens, and a method for preparing the lens including the heating device. 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. When the vehicle is driving in continuous ...
