Detailed Description
Embodiments of the present application are described in detail below. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the present disclosure. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications. The reagents used are conventional products which are not indicated by manufacturers and can be obtained by market purchase.
The existing camera lens has single function, single appearance effect and poor decoration effect.
In order to solve the above technical problems, the present invention provides a camera lens, and referring to fig. 1, a camera lens 100 includes a substrate, the substrate includes a window area a and a non-window area B surrounding the window area a, the non-window area B of the substrate is provided with a first shielding portion and a second shielding portion D, the first shielding portion includes a first shielding sub-portion C and a second shielding sub-portion E, the first shielding sub-portion C and the second shielding sub-portion E surround the window area a, the second shielding portion D is located between the first shielding sub-portion C and the second shielding sub-portion E, and a transmittance of the second shielding portion and the substrate under visible light is 27-37%. Therefore, the camera lens has a local semi-transparent effect, can realize a light supplementing effect during microscopic imaging, and ensures that the microscopic imaging is fine and clear. Compared with the traditional camera lens, the lens has the light supplementing function. In addition, the camera lens can hide a structure below the camera lens. In addition, the camera lens of this application presents different visual effects when turning off the light and bright, has gorgeous outward appearance effect. Due to the fact that the camera lens is different from the traditional camera lens in appearance, the experience degree of a user can be improved, and the market competitiveness of a product is further improved.
The second shielding portion is provided on the substrate, and the transmittance of the second shielding portion and the substrate in visible light is 27 to 37%, which means that the substrate and the second shielding portion are laminated at the position of the second shielding portion, and the transmittance of the lens in visible light at the position is 27 to 37%.
For convenience of understanding, the principle that the camera lens can achieve the above functions is briefly described below:
along with the promotion of present electronic equipment to the function requirement of making a video recording, the module of making a video recording of single effect can not satisfy the demand already. For example, many current electronic devices are equipped with a camera module having a macro, tele, or wide effect. However, the current camera module still has no microscope function. Therefore, if the microscopic function can be realized, the function and application range of the electronic device will be further improved. The camera lens that this application provided can with the camera module in have the microscopic function to and the light filling subassembly cooperatees, realize the shooting of photomicrograph. Specifically, the first sub-part and the second of shielding of camera lens shield the component that the sub-part can shield camera lens below, and the second shields portion and base plate because the transmissivity is higher, can be when the light filling subassembly is luminous, carries out the light filling to the lens to further promote microscopical effect, make the photo of shooing more clear. Further, the light filling subassembly can include leaded light post and light source, and when needs used the microscope function, open the light source and make it luminous, the light that the light source sent can pass through the leaded light post, then shields portion and base plate through the second on the camera lens, shines on the object of shooing, comes to carry out the light filling to the lens.
The shape of the camera lens includes, but is not limited to, a circle, an ellipse, a square, a rectangle, a polygon, or an irregular figure. It should be noted that the shape of the camera lens in the drawings of the present invention is only for illustrative purposes, and should not be construed as limiting the present invention, in other words, the shape of the camera lens may be other shapes as mentioned above. The invention does not limit the size of the lens of the camera, and technicians can select the lens according to use requirements.
According to an embodiment of the invention, the substrate is sapphire or glass and the thickness of the substrate is 0.4-1mm, such as 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1 mm. If the thickness of the substrate is too small, the strength of the substrate is too small, and the substrate is liable to crack. If the thickness of the substrate is too large, the production and manufacturing are difficult, the thickness and the quality of the electronic equipment can be further increased due to the too large thickness, the development trend of thinning the electronic equipment is not met, and the production cost can be increased due to the too large thickness.
The transmittance of the substrate under visible light is 85-87%. Therefore, the substrate can be matched with the second shielding part, so that the light transmittance of the second shielding part and the substrate meets the requirement of a microscope. In addition, enough light can penetrate through the window area A of the camera lens, so that the lens positioned below the camera lens can shoot an object more clearly.
According to the embodiment of the invention, the wavelength of the visible light is 380-780 nm.
According to an embodiment of the present invention, the non-window area of the substrate is provided with a first shielding sub-portion and a second shielding sub-portion, and the first shielding sub-portion and the second shielding sub-portion include a light shielding layer. Fig. 2 is a cross-sectional view of a lens for a camera according to an embodiment of the present invention, and referring to fig. 2, a light shielding layer 120 is disposed on a substrate 110. Further, a material forming the light-shielding layer 120 is black ink. Therefore, by arranging the light shielding layer 120 in an area without light transmittance requirement, the internal components under the lens of the camera can be better shielded, and in addition, the positions corresponding to the first shielding sub-part and the second shielding sub-part and the window area have different visual effects, so that a better visual impact effect is achieved.
Further, the thickness of the shading layer is 5-6 μm, and internal elements below the lens can be better shaded at the thickness, so that the lens has better appearance effect.
According to the embodiment of the invention, the second shielding part D comprises a texture layer 130, an optical coating layer 140 and a semi-permeable ink layer 150 which are sequentially laminated. Referring to fig. 3, the second shielding part D is disposed on the substrate 110, and the texture layer 130 is disposed at a side close to the substrate 110. Therefore, the substrate 110, the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 are mutually matched, so that the transmittance of the second shielding part and the substrate under visible light is 27-37%, and the requirement of a microscope on light is met.
Referring to fig. 4, the light shielding layer 120 and the second shielding portion D (the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150) are disposed on the same side of the substrate 110.
According to an embodiment of the present invention, the surface of the texture layer 130 on the side away from the substrate 110 has a plurality of stripes, and the spacing between adjacent stripes is 0.03-0.07mm, such as 0.03mm, 0.04mm, 0.05mm, 0.06mm or 0.07 mm. The lines of the stripes in the textured layer are 0.03-0.07mm, such as 0.03mm, 0.04mm, 0.05mm, 0.06mm, or 0.07 mm. Thus, if the pitch between adjacent stripes and the line width of the stripes are too small, the real effect of the stripes is not easily seen. If the pitch of adjacent stripes and the line width of the stripes are too large, the fineness may be poor. When the distance between adjacent stripes is 0.03-0.07mm and the line width of the stripes is 0.03-0.07mm, the fineness of the lens of the camera is higher and the appearance effect is better.
Further, the transmittance of the texture layer 130 under visible light is 94-98%, so that the texture layer 130 can cooperate with other layer structures of the second shielding part and the substrate 110, and the transmittance of the second shielding part and the substrate can meet the requirement of a microscope.
Further, the thickness of the texture layer is 9-11 μm, and at this thickness, a better appearance effect can be obtained.
According to the embodiment of the invention, the material for forming the optical coating layer 140 is SiO2、TiO2And Pb2O5At least one of (1). Further, the thickness of the optical coating layer 140 is 260-290nm, such as 260nm, 265nm, 270nm, 275nm, 280nm, 285nm or 290 nm. The number of the optical coating layer is not limited in the present invention, and specifically, the number of the optical coating layer may be 1, 2, 3, 4, 5, 6, 7 or more. When the number of the optical coating layers is more than 2, the optical coating layer comprises a plurality of optical coating sub-layers, wherein the thickness of each optical coating sub-layer can be the same or different, as long as the sum of the thicknesses of the optical coating sub-layers is 260-290 nm.
Furthermore, the transmittance of the optical coating layer under visible light is 45-61%. Therefore, the optical coating layer can be matched with other layered structures and the substrate of the second shielding part, so that the light transmittance of the second shielding part and the substrate can meet the requirement of a microscope.
According to the embodiment of the present invention, the material forming the semi-permeable ink layer 150 is gray phase ink, so that the color of the photographed picture can be made close to the actual color, and the advantage of small hue deviation is obtained.
Further, the thickness of the semi-permeable ink layer 150 is 5-8 μm, and the photo taken by the semi-permeable ink layer can be better.
Furthermore, the transmissivity of the semi-permeable ink layer under visible light is 53-63%. Therefore, the semi-permeable ink layer can be matched with other layered structures and the substrate of the second shielding part D, so that the light transmittance of the second shielding part and the substrate can meet the requirement of a microscope.
It should be noted that fig. 4 and fig. 7 only illustrate the positions of the respective layered structures on the substrate, and the thickness of the respective layered structures in the drawings should not be construed as limiting the application. Specifically, as mentioned above, the thickness of the light-shielding layer 120 is 5-6 μm, the thickness of the texture layer 130 is 9-11 μm, the thickness of the optical coating layer 140 is 260-290nm, and the thickness of the semi-permeable ink layer 150 is 5-8 μm, so that the camera lens can have better effect. In this case, although the surface of the substrate is not uniform, the thickness of the layered structure on the substrate is small relative to the thickness of other components of the electronic device, and the thickness unevenness at different positions of the lens during the assembly of the electronic device hardly affects the other components and can satisfy the assembly requirements.
According to the invention, the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 are arranged on the substrate 110, so that the effects of light supplement, mechanism hiding, uniform light guiding, gorgeous appearance and the like of a microscope can be realized, the expressive force of the camera lens 100 is greatly improved, the appearance has layering and gorgeous appearance, different functional requirements and appearance effects can be presented in different scenes, brand new experience is brought to users, the use viscosity of the users is improved, and the expressive force of products is further improved.
According to an embodiment of the invention, the camera lens 100 further comprises an anti-fingerprint film layer 160.
The substrate 110 has a first surface 110a and a second surface 110b opposite to each other, and referring to fig. 5, 6 and 7, the light-shielding layer 120, the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 (i.e., the second shielding portion) are disposed on the first surface 110a of the substrate 110. The anti-fingerprint film layer 160 is disposed on the second surface 110 b.

That is, the anti-fingerprint film layer 160 is not on the same side of the substrate 110 as the light-shielding layer 120, the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150.
Further, the anti-fingerprint film layer 160 covers the substrate 110, i.e., the anti-fingerprint film layer 160 covers the window region a and the non-window region B. Therefore, the camera lens has the advantages of fingerprint resistance, oil resistance, dust resistance and the like.
Further, in electronic equipment, anti fingerprint rete 160 on the camera lens is located electronic equipment's the outside, can prevent that greasy dirt, fingerprint etc. from influencing the shooting effect of camera lens.

The first shielding sub-part C and the second shielding sub-part E are positioned at two sides of the second shielding part D and comprise a shielding layer, so that the lenses at the positions of the first shielding sub-part C and the second shielding sub-part E have shielding functions, and internal elements positioned below the positions can be effectively shielded. In addition, the second shielding portion D, the first shielding sub-portion C and the second shielding sub-portion E have different layered structures, so that the lens in the non-window area B has different appearance effects, and the visual experience of the user is improved.
