Embodiment Construction
[0025] Such as figure 1 shown, see also figure 2 , 3 , 4. In a preferred embodiment of the present invention, it includes a circuit board 1, a seat 2 fixed on the surface of the circuit board 1, a lens assembly 3 fixed in the seat 2, an image sensor 4 located in the seat 2, and a seat 2 fixed on the circuit board. 1 flash on 5.
[0026] The lens assembly 3 includes a lens barrel 301 and lenses arranged in the lens barrel 301. It can be understood that the center of the end face of the lens barrel 301 should be provided with a light-transmitting hole, and the lenses include a single-convex aspheric lens 302 and a double-convex aspheric lens. Lens 303, the light incident surface of biconvex aspheric lens 303 and the light emitting surface of single convex aspheric lens 302 are pasted and fixed, and the light transmission center of single convex aspheric lens 302 and the light transmission hole position of lens barrel 301 must be Corresponding. Both the flashlight 5 and the...

The invention relates to a camera module, which comprises a circuit board, a bearing, a lens assembly, an image sensor and a flash lamp, wherein the bearing is fixedly arranged on the surface of the circuit board; the lens assembly is fixedly arranged in the bearing; the image sensor is located in the bearing; the flash lamp is fixedly arranged on the circuit board; the lens assembly comprises a lens cone and lenses arranged in the lens cone; the center of the end face of the lens cone is provided with a light hole; the lenses comprise a single convex type aspheric lens and a biconvex type aspheric lens; the light incidence face of the biconvex type aspheric lens and the light emergence face of the single convex type aspheric lens are fixed in the manner of pasting; the diaphanous center of the single convex type aspheric lens corresponds to the light hole of the lens cone in position; the flash lamp and the image sensor are respectively and electrically connected with the circuit board; and the photosensitive center of the image sensor corresponds to the diaphanous center of the lens assembly in position. Light rays can be supplemented for the camera module by the flash lamp in a dark environment, so that a clear image can be shot by the camera module even at night, and moreover, the light transmittance can be greatly improved by the adopted single convex type aspheric lens and the adopted biconvex type aspheric lens, and therefore, the shot image is clearer.
Description
technical field [0001] The invention relates to a camera for electronic communication products, more specifically, to an automatic zoom lens module. Background technique [0002] Camera modules with flash light are widely used in mobile phones, MP4, video phones, toys, POS machines and other electronic products. With the development of the times and the advancement of technology, the application of camera modules is increasing rapidly. At the same time, the competition in the camera module industry is becoming more and more fierce. The relative brightness of the lens assembly used in the traditional camera module is only 55, and the image is not clear enough, and the shooting effect at night is not ideal, which seriously affects the overall performance of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a camera module for the above-mentioned defects of the prior art. [0004] The technical solution...
