BACKGROUND
Personal electronic devices are commonly used for communication, entertainment purposes, as well as Internet access and a variety of other purposes. Examples of personal electronic devices include smartphones, tablet computers, gaming devices, audio players, video players, cameras, portable computers, two-way radios, GPS receivers, smart glasses, virtual reality glasses or helmets, masks or eyewear including an electronic display, and/or other portable devices. Protective cases for electronic devices provide protection for the electronic device from various forms of damage, including damage from dust, water, snow, dirt, and drops. Exemplary protective cases are disclosed in U.S. Pat. Nos. 8,342,325 and 9,300,344, the disclosures of which are hereby incorporated by reference in their entirety.
Many electronic devices include a camera and associated flash, such as a flash LED, for providing light when taking a picture with the camera. The camera and flash are often positioned in close proximity, such as on the rear of the electronic device. It can be desirable to include a lens covering with the protective case to protect the camera and/or flash from damage, such as scratches or water.
In some electronic devices, the camera is configured to adjust exposure time and/or other settings based on the status of the flash. However, the presence of a protective lens over one or both of the camera and flash reduces the amount of light transmitted from the flash to subject, as well as the light from the subject to the camera aperture. Additionally, the surface of the protective lens may reflect or otherwise transmit a portion of the light from the activated flash directly to the camera without passing through the protective lens.
Improvements in the foregoing are desired.
SUMMARY
In one example, a lens for a protective case for an electronic device having a camera and flash is provided. The lens includes a first optically transparent portion configured to be positioned proximate the camera and a second optically transparent portion configured to be positioned proximate the flash. The first optically transparent portion has a first surface that is a first distance from a back surface of the electronic device. The second optically transparent portion has a second surface that is a second distance from a back surface of the electronic device, wherein the second distance is less than the first distance.
In one example, a protective case for an electronic device having a camera and a flash is provided. The protective case includes a lens comprising a first lens portion and a second lens portion.

Protective case 20 encases at least a portion of electronic device 10 to prevent device 10 from damage. Protective case 20 may comprise a single-piece into which electronic device 10 is fitted, or protective case 20 may include two or more pieces removably attached to each other through one or more clasping or coupling mechanisms. Exemplary protective cases 20 are disclosed in U.S. Pat. Nos. 8,342,325 and 9,300,344, the disclosures of which are hereby incorporated by reference in their entirety.
Protective case 20 includes at least one recess or aperture 22 providing optical access to camera 12 and flash 14 of electronic device 10 when electronic device 10 is inserted or enclosed in protective case 20. Aperture 22 is at least partially covered by one or more lenses 24 for protecting camera 12 and/or flash 14. Exemplary lenses 24 include the lenses 110, 210, 310, 410, 510, 610 illustrated in FIGS. 3A, 4A, 5A, 6A, 7A, and 8A. As used herein, a lens may comprise a single piece of transparent material covering both camera 12 and flash 14, or a lens may comprise two or more pieces of transparent material, each covering at least a portion of camera 12 and/or flash 14.
Lens 24 includes an optically transparent region allowing light to be transmitted through lens 24. The optically transparent region allows for light emitted by flash 14 to pass through lens 24 and illuminate a target area, and also allow light from the target area to pass through lens 24 to camera 12.
In some embodiments, the lens 24 has an optical transmissivity of at least about 90%, at least about 95%, at least about 97%, at least about 98%, or greater. In some embodiments, lens 24 includes one or more coatings, such as anti-reflective coatings, to reduce the amount of light lost due to reflection. In some embodiments, the optically transparent region of lens 24 is formed from sapphire or glass, such as a fortified and/or tempered glass such as Alpha Glass available from Otter Products, LLC, Gorilla Glass available from Corning Inc., Dragontail glass available from Asahi Glass Co., or Xensation available from Schott AG. In some embodiments, the optically transparent region of lens 24 is formed from a transparent plastic, such as nylon or polyethylene terephthalate (PET). In some exemplary embodiments, the optically transparent region of lens 24 has a thickness as little as 0.1 mm, 0.2 mm, 0.3 mm, as great as 0.33 mm, 0.4 mm, 0.5 mm, or within any range defined between any two of the foregoing values, such as 0.1 mm to 0.5 mm, or 0.2 mm to 0.4 mm.
Referring next to FIG. 2, a portion of an electronic device 10 is illustrated including camera 12 and flash 14. As illustrated in FIG. 2, camera 12 and flash 14 are positioned on a back surface 16 of electronic device 10 near a side surface 18. In other embodiments, camera 12 and/or flash 14 may be positioned on a front surface 17 or side surface 18 of electronic device, or may be positioned remotely from side surface 18. In some embodiments, camera 12 and flash 14 are positioned on back surface 18 proximate a rear corner of electronic device 10. In some embodiments, camera 12 and flash 14 are positioned in an upper central portion of back surface 18 of electronic device 10.
As shown in FIG. 2, at least one of camera 12 and flash 14 terminates at a position that is not substantially level with surface 16. In the illustrated embodiment, camera 12 includes a housing 30 extending a distance “d” above back surface 16 of electronic device. Flash 14 terminates at a position substantially flush with back surface 16. In other exemplary embodiments, camera 12, flash 14, or both may independently extend above or below surface 16.
Referring next to FIGS. 3A-3C, a first embodiment of lens 24 is illustrated as stepped lens 110. FIG. 3A illustrates a cross-section of a portion an exemplary protective case 20 including lens 110 covering the camera 12 and flash 14 of installed electronic device 10. As illustrated in FIG. 3A, the housing 30 of camera 12 extends above the back surface 16 of electronic device 10. FIG. 3B illustrates a perspective view of lens 110. FIG. 3C illustrates a corner portion of protective case 20 including lens 110.
Stepped lens 110 comprises a first portion 112 having an optically transparent region covering camera 12 and a second portion 114 having an optically transparent region covering flash 14. In some embodiments, stepped lens 110 is at least partially received within a recess 26 of case 20 to secure stepped lens 110 to case 20.
In some exemplary embodiments, the first portion 112 defines a first plane and the second portion 114 defines a second plane where the first and second planes are not co-planar. Illustratively, first portion 112 including a first optically transparent region proximate installed camera 12 and second portion 114 including a second optically transparent region proximate installed flash 14 are joined by an offset or step such that a distance di is present between the top surfaces of each portion. In other embodiments, the top surfaces of the first portion 112 and the second portion 114 are co-planar and no step is present between the top surfaces of each portion.
As illustrated in FIGS. 3B and 3C, first portion 112 and second portion 114 are each substantially D-shaped. First portion 112 and second portion 114 are illustratively attached by a suitable adhesive 40. In some exemplary embodiments, adhesive 40 is optically opaque to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 110.
Stepped lens 110 includes a light-blocking ink 42 extending around an outer portion of first portion 112 and second portion 114. Ink 42 is illustratively edge painted or pad printed to stepped lens 110 to optically isolate edges of the stepped lens 110. As illustrated in FIG. 3B, the ink 42 is printed around an outer perimeter of each of first portion 112 and second portion 114. A gasket 44 is illustratively provided between the case 20 and the lower surfaces of first portion 112 and second portion 114 to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 110. In some embodiments, gasket 44 may include an adhesive to secure stepped lens 110 to case 20.
As illustrated in FIG. 3A, the stepped lens 110 allows the first portion 112 to be positioned relatively close to the end of the housing 30 of camera 12 and the second portion 114 to be positioned relatively close to the flash 14. In some embodiments, the close positioning allows for higher transmissivity and reduced reflections through stepped lens 110.
FIG. 3A further illustrates the field of view 32 for camera 12 and field of view 34 for flash 14. The area encompassed by fields of view 32, 34 may also be referred to as keep out zones or keep out cones. It can be desirable to keep the fields of view 32, 34 as clear from obstruction as possible. As shown in the exemplary embodiment of FIG. 3A, the use of the stepped lens 110 allows for no intrusion of the case 20 into the field of view 32 for camera 12. The intrusion into the field of view 34 for the flash 14 is limited to a small amount of the first portion 112 associated with the step between the first portion 112 and second portion 112. This allows for a relatively high level of the light from flash 14 to be transmitted through stepped lens 110 and received by camera 12.
Referring next to FIGS. 4A-4D, a second embodiment of lens 24 is illustrated as dual lens 210. Dual lens 210 includes several similar elements as stepped lens 110 of FIGS. 3A-3C, and similar part numbers are used to describe similar elements. FIG. 4A illustrates a cross-section of a portion an exemplary protective case 20 including lens 210 covering the camera 12 and flash 14 of installed electronic device 10.

In some exemplary embodiments, the first portion 212 and first optically transparent region define a first plane and the second portion 214 and second optically transparent region define a second plane where the first and second planes are not co-planar. Illustratively, first portion 212 and second portion 214 are discontinuous and separated by an offset or step such that a distance d2 is present between the top surfaces of each portion. In other embodiments, the top surfaces of the first portion 212 and the second portion 214 are co-planar and no step is present between the top surfaces of each portion.
As illustrated in FIGS. 4B-4D, first portion 212 and second portion 214 are each substantially circular. FIGS. 4B and 4C each illustrate first portion 212. In some embodiments second portion 214 the same shape as first portion 212 shown in FIG. 4D. First portion 212 and second portion 214 are illustratively attached to case 20 by a suitable adhesive 40. In some exemplary embodiments, adhesive 40 is optically opaque to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 210.
Dual lens 210 includes ink 42 extending around an outer portion of first portion 212 and second portion 214. A gasket 44 is illustratively provided between the case 20 and the lower surfaces of first portion 212 and second portion 214 to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 210.

As illustrated in FIG. 4A, the dual lens 210 allows the first portion 212 to be positioned relatively close to the end of the housing 30 of camera 12 and the second portion 214 to be positioned relatively close to the flash 14. In some embodiments, the close positioning allows for higher transmissivity and reduced reflections through lens 210.
As shown in the exemplary embodiment of FIG. 4A, the use of the dual lens 210 allows for no intrusion of the case 20 into the field of view 32 for camera 12. The intrusion into the field of view 34 for the flash 14 is limited to a small amount of the first portion 212. This allows for a relatively high level of the light from flash 14 to be transmitted through lens 210 and received by camera 12.
Referring next to FIGS. 5A-5E, a third embodiment of lens 24 is illustrated as stacked lens 310. Stacked lens 310 includes several similar elements as stepped lens 110 of FIGS. 3A-3C, and similar part numbers are used to describe similar elements.

In some embodiments, a gasket 44 is illustratively provided between the case 20 and the lower surfaces of first portion 312 and second portion 314 to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 310. In some embodiments, gasket 44 may include an adhesive to secure lens 310 to case 20.
As illustrated in FIG. 5A, the stacked lens 310 allows the first portion 312 to be positioned relatively close to the end of the housing 30 of camera 12 and the second portion 314 to be positioned relatively close to the flash 14. In some embodiments, the close positioning allows for higher transmissivity and reduced reflections through lens 310.
As shown in the exemplary embodiment of FIG. 5A, the use of the lens 310 allows for no intrusion of the case 20 into the field of view 32 for camera 12. The intrusion into the field of view 34 for the flash 14 is limited to a small amount of the first portion 312. This allows for a relatively high level of the light from flash 14 to be transmitted through lens 310 and received by camera 12.
Referring next to FIGS. 6A-6E, a fourth embodiment of lens 24 is illustrated as formed lens 410.

In some embodiments, first portion 612 and/or second portion 614 includes ink 42 to optically isolate the first portion 612 from the second portion 614. As shown in FIG. 8B, in some embodiments, a gasket 44 is illustratively provided between the case 20 and lens 610 to prevent light from bleeding from flash 14 directly to camera 12 without passing through lens 610. In some embodiments, gasket 44 may include an adhesive to secure lens 610 to case 20.
Any suitable shape for first portion 612 and second portion 614 may be used. For example, as illustrated in FIG. 8C, in some embodiments the second portion 614 has a substantially circular shape, and the first portion 612 has two substantially straight edges, a convexly curved edge, and a convexly curved edge adjacent the edge of the second portion 614. As illustrated in FIG. 8D, in other embodiments, each of the first portion 612 and the second portion 614 are substantially circular, but a portion of either portion is missing, such as the missing notch from first portion 612 illustrated in FIG. 8D. As shown in FIGS. 8C and 8D, in some embodiments, second portion 614 has a larger radius than first portion 612 to accommodate the expanded field of view of the flash 14 due to its position below the housing 30 of camera 12 (see FIG. 8B).
Referring next to FIGS. 9A-9D, another exemplary protective case 20 is illustrated. In the exemplary embodiment shown in FIG. 9A, case 20 includes a seventh embodiment of lens 24 illustrated as lens insert 710. Lens insert 710 includes several similar elements as stepped lens 110 of FIGS. 3A-3C, and similar part numbers are used to describe similar elements. As shown in FIG. 9C, case 20 further includes an opening 27 on a front side of case 20 configured to allow electronic device 10 (not illustrated in FIG. 9C) to be received within an interior 28 of case 20 such that camera 12 and flash 14 are aligned with lens insert 710. Case 20 further includes a rear surface 29 configured to at least partially cover and protect electronic device 10 when electronic device 10 is installed within protective case 20.
Lens insert 710 comprises a first lens portion 712 covering camera 12 and a second lens portion 714 covering flash 14 of electronic device 10 when electronic device 10 is installed within protective case 20. In some exemplary embodiments, first lens portion 712 and second lens portion 714 are formed from separate pieces of transparent material. Lens insert 710 is at least partially received within a recess 26 of case 20.
As shown in FIG. 9D, the first lens portion 712 defines a first plane and the second lens portion 714 defines a second plane where the first and second planes are not co-planar. As illustrated in FIG. 9D, the plane of the first lens portion 712 is positioned closer to a rear surface 29 of the protective case 20 and the plane of second lens portion 714 is positioned closer to the interior 28 of case. As illustrated in FIGS. 9B and 9C, in some embodiments first lens portion 712 and second lens portion 714 are each substantially D-shaped.
First lens portion 712 and second lens portion 714 are illustratively positioned within a housing 716. Housing 716 is illustratively positioned within aperture 26 and secured to case 20 with a suitable adhesive 40. Referring to the exemplary embodiment illustrated in FIG. 9B, housing 716 includes a perimeter lip 718 extending around an outer perimeter of housing 716. As shown in FIG. 9D, a suitable adhesive 40 adheres the perimeter lip 718 to the rear surface 29 of protective case 20, thereby affixing lens insert 710 to the remainder of protective case 20. In some exemplary embodiments, adhesive 40 extends around perimeter lip 718 of housing 716 to provide a waterproof and/or dustproof seal between the interior 28 of protective case 20 and an exterior environment.
Referring again to FIG. 9B, in some exemplary embodiments housing 716 includes one or more notches 720 around an internal surface of perimeter lip 718. Notches 720 provide distinct aperture widths for an upper portion 716A of housing 716 proximate first lens portion 712 and a lower portion 716B of housing 716 proximate second lens portion 714. First lens portion 712 and second lens portion 714 each have a width corresponding to the width of the aperture of either the upper portion 716A or lower portion 716B of housing, providing ease in placement and orientation of the first lens portion 712 and second lens portion 714 into the appropriate portion of housing 716 during manufacture and assembly of lens insert 710.
As shown in FIGS. 9C and 9D, the bottom of lens insert 710 further includes one or more gaskets 722 extending towards an installed electronic device 10 (not shown in FIGS. 9C and 9D). In some exemplary embodiments, gasket 722 is configured to contact and/or compress against a back side of the installed electronic device. Each gasket 722 may be positioned to at least partially surround camera 12 and/or flash 14 of the installed electronic device 10. As illustrated in FIGS. 9C and 9D, gasket 722 is configured to surround the flash 14 of the installed electronic device.
Gasket 722 is illustratively formed from a compressible and light-blocking material, such as a closed cell foam. In some embodiments, gasket 722 prevents all or substantially all light from flash 14 of installed electronic device 10 from being transmitted through gasket 722, while the compressibility of gasket 722 allows it to contour to the surface of the installed electronic. In this way, gasket 722 advantageously prevents light from flash 14 of installed electronic device 10 from being transmitted to camera 12 through a path other than through second lens portion 714 and first lens portion 712.
Lens 710 includes ink 42 extending around at least a portion of first lens portion 712 and/or second lens portion 714. Ink 42 is a light-blocking material configured to prevent light from entering the portion of first lens portion 712 or second lens portion 714 covered with ink 42.
Referring next to FIG. 9E, an exemplary first lens portion 712 is illustrated. At least a portion of side surface 724 is coated with ink 42. As illustrated in FIG. 9E, ink 42 fully covers side surface 724A, positioned closest to second lens portion 714 (see FIG. 9D) and flash 14 when electronic device 10 is installed in protective case 20. In this way, ink 42 on side surface 724A prevents light from flash 14 from entering first lens portion 712 from side surface 724A.
As further shown in FIG. 9E, at least a portion of the perimeter of top surface 726 may be coated with ink 42. As illustrated in FIG. 9E, the full perimeter of top surface 726 is coated with ink 42. In some exemplary embodiments, ink covers at least the perimeter portion 726A of the top surface 726 positioned closest to second lens portion 714 (see FIG. 9D) and flash 14 when electronic device 10 is installed in protective case 20. In this way, ink 42 on perimeter portion 726A prevents light from flash 14 from entering first lens portion 712 from perimeter portion 726A.
At least a portion of the perimeter of bottom surface 728 opposite top surface 726 may be coated with ink 42. In some exemplary embodiments, the full perimeter of bottom surface 728 is coated with ink 42. In some exemplary embodiments, ink covers at least the perimeter portion 728A of the bottom surface 728 positioned closest to second lens portion 714 (see FIG. 9D) and flash 14 when electronic device 10 is installed in protective case 20. In this way, ink 42 on perimeter portion 728A prevents light from flash 14 from entering first lens portion 712 from perimeter portion 728A.
In some exemplary embodiments, ink 42 covers at least a portion of side surface 724, and top perimeter portion 726, such as side surface 724A and top perimeter portion 726A. In some exemplary embodiments, ink 42 covers at least a portion of side surface 724, and bottom perimeter portion 728, such as side surface 724A and bottom perimeter portion 728A. In some exemplary embodiments, ink 42 covers at least a portion of side surface 724, top perimeter portion 726, and bottom perimeter portion 728, such as side surface 724A, top perimeter portion 726A, and bottom perimeter portion 728A. In some exemplary embodiments, ink 42 fully covers side surface 724, top perimeter portion 726 and bottom perimeter portion 728. Without wishing to be held to any particular theory, it is believed that covering at least side surface 724A and bottom perimeter portion 728A with light-blocking ink prevents all or nearly all light from flash 14 of installed electronic device 10 from bleeding through first lens portion 712 upon taking a picture with camera 12, thereby improving the quality of the photographic image taken by camera 12.
Second lens portion 714 may have ink 42 positioned on the same or different edge surfaces as first lens portion 714.
