DETAILED DESCRIPTION OF THE DISCLOSURE

[0023] FIG. 1 shows a piece of equipment having a magnification device associated with it. The equipment has a cover 1 with an aperture 2, a lens 3, and a light 4 in the body of the equipment. The equipment can be, for example, a mobile device such as a cell phone or IPAD manufactured by Apple or Samsung, a smartphone such as the Apple iPhone 7, iPhone 7 Plus, a Samsung Galaxy Grand Prime Plus, iPhone 6s or Galaxy S8, or the like which includes a digital camera function associated with the lens and the light in the body of the equipment so that the equipment is capable taking digital photographs.

[0024] A magnification and lighting device is attached to cover 1. The magnification and lighting device includes a carrier assembly having a carrier member 10 which is, for example, a generally round and essentially flat piece having a major surface that extends around about 270 degrees (angle alpha). Carrier member 10 includes an opening or open area 11, which extends about 90 degrees (angle beta), and optical assemblies 12,13,14,15 mounted on carrier member 10. The optical assemblies include at least one optical component such as a lens for magnification of light that is to be projected through the lens and into the lens in the body of the equipment. In addition, one or more of the optical assemblies can include light sources 30,40 respectively adjacent thereto for collecting light form the light in the body of the equipment projecting light toward the object(s) to be photographed. Carrier member 10 is rotatably mounted to cover 1 so that rotation in direction A moves the optical assemblies into alignment with the lens 3 and light 4. FIG. 1 depicts open area 11 aligned with the lens 3 and light 4 which renders carrier member 10 clear of lens 3 and light 4, and FIG. 2 depicts carrier member 10 rotated into a position in the direction of arrow A where optical assembly 12 is aligned with lens 3 and light 4. Alternatively, open area 11 can be fully or partially occupied by a carrier piece (not shown) that can be opaque, clear, colored, filtered, and/or comprise a convex or concave lens and formed of a material such as glass or plastic. Carrier member 10 can be shapes other than the generally round 270 degree form as shown, for example, it can be triangular, octagonal, crescent, oval, or another suitable shape and all such shapes can include an open area or a carrier piece as previously described.

[0025] FIG. 2 more fully describes the magnification and lighting device. Carrier member 10 is rotatably mounted to cover 1 via a support 21. As shown by the cross section of support 21 (FIG. 4), support 21 is operatively associated with carrier member 10 such that carrier member 10 can be rotated and releasably locked in positions such that open area 11 and optical assemblies 12,13,14,15 can be rotated into alignment with lens 3 and light 4 in the body of the equipment. For example, support 21 and carrier member 10 can be formed with flexible members that releasably lock the carrier member's position relative to cover 1. In one example, the flexible members may be in the form of a ratchet and pawl construction 16,24 whereby rotation of carrier member 10 along direction A will result in the carrier member being releasably fixed in place according to the desired disposition of carrier member 10 relative to the lens 3 and light 4 in the body of the equipment. Alternatively, the rotational position of carrier member 10 can be held by one or more flexible detents, ridges, springs, pins, screws, magnets, or other components formed on the support 21 and carrier member 10. In addition, support 21 can include a structure allowing separation of carrier member 10 from support 21. For example, support 21 can be at least partially threaded at the upper portion thereof and a holding member, such as for example a nut 21a, is operatively attached to the support, such as by screwing the nut to the upper portion and thereby releasably holding the carrier member in place. As an alternative to a thread/nut arrangement, a snap-fit structure can be formed on carrier member 10 and support 21. In this way, the operator can remove carrier member 10 and replace it with other carrier members as desired. The other carrier members are interchangeable with carrier member 10 and can have different lenses, filters, light source arrangements, splitters, optical fibers, diffusers or other optical and/or photographic components mounted thereon.

[0026] Referring to FIG. 3, support 20 includes a base 22 and attachment area 23. Base 22 provides firm mechanical support for carrier 10. Attachment area 23 attaches the magnification and lighting device to the cover with, for example, an adhesive, or Velcro material such as a micro Velcro material. Optical assembly 12 is aligned with lens 3 and light 4, and optical assembly 14 is in a non-aligned position relative to lens 3 and light 4 of the equipment. Optical assemblies 12 and 14 each include a respective light source 30,40. In addition to or in lieu of the adhesive and/or Velcro, attachment area 23 and base 22 can be extended to include one or more grippers that extend to the edge or edges of the device cover 1. The grippers can be in the form of one or more flexible extensions 22a,22b (FIG. 11) which are flexible and can be bent and extended partially or all the way around the cover during installation onto cover 1. For example, the grippers can have one or more frictional areas 22c,22d that can grip the short sides of the cover or can extend around to engage the longer side of the cover. Alternatively, support 21, base 22, and attachment area 23 can be formed monolithically with cover 1 (FIG. 12).

[0027] FIG. 5 provides a further illustration of optical assembly 12 and light source 30. Light source 30 includes one or more optical traces such as optical fiber, for example, a light transmitting plastic or glass optical fiber or a combination hereof, which can be clear or colored/filtered, that are embedded in, or attached on the outside of, carrier member 10. In addition, light source 30 includes optical traces 31,31, each having a light emitter 34,35 respectively associated therewith. Light collector 33 is aligned with light 4 in a way that maximizes the amount of light being collected or coupled into the optical traces. In an exemplary operation, light 4 emits light which is collected by collector 33 and which passes through a splitter 36. The light is directed into paths 31,32 and is emitted by light emitters 34,35. The light is directed in direction B toward object(s) to be photographed by the equipment.

[0028] FIG. 6 further illustrates optical assembly 14. Optical assembly 40 includes light source 40, which employs optical components, alone or in combination, that includes a light transmission path that results in diffused or focused light. For example, two optical diffusers 41,42 can be mounted to carrier member 10 such as by adhesive bonding. Optical ridges 41a,42a are respectively formed on at least one respective surface of optical diffusers 41,42. Light enters the diffuser 41 which diffuses light from a lower side surface of the diffuser 41 in a first optical path, and the light moves to optical ridges 41a. The light is emitted from optical ridges 41a toward diffuser 42, it enters optical diffuser 42 and is further diffused by diffuser 42. Optical ridges or edges 41a,42a are operative to diffuse light in the first optical path which ultimately projects from the diffusers. In an exemplary operation, light is emitted by light 4 in the body of the equipment toward diffuser 41, which in turn transmits light toward the object(s) to be photographed and at the same time projects light to diffuser 42 along direction C parallel to the major surface of the equipment. Diffuser 42 collects and reflects the light and projects or transmits it toward the object(s) to be photographed along direction D which is generally perpendicular to the major surface of the equipment. Alternatively, lenses can be formed instead of optical ridges whereby the len(s) will focus light on the object(s) to be photographed as opposed to diffusing the light. However, combinations of diffusers and lenses, and other components such as for example, splitters, filters, optical traces, and optical fibers can be used.

[0029] Alternative optical assemblies can include, in addition to a lens or as a substitute, other optical components such as optical filters and attenuators. In addition, the optical assemblies can include more than one lens such as an exemplary optical assembly 15 including a telescopic configuration, and example of which is shown in FIG. 10. Optical assembly 15 includes two lenses 15a, 15b supported by a housing 15c. The distance between the lenses can be adjusted along direction F by use of adjustment 15d which can be a sliding mechanism, a rack and pinion, screw adjustment or the like. Optical assembly 15 can be mounted to carrier 50, although it could be part of carrier 10 as well.

[0030] FIGS. 7-9 describes a second embodiment of the magnification and lighting device. FIG. 7 depicts a carrier member 50, which is moved by linear action along direction E. Carrier member 50 includes a support 51 and support sections 50a,50b. Optical assemblies 12,13,14,15 as described above with reference to FIGS. 1-6 can be mounted on or in carrier member 50, in addition to variations thereof, and carrier member 50 can be slidably adjusted to be clear of lens 3 and light 4 in the body of the equipment as well. For example, the cross section of FIG. 8 depicts an optical assembly 60 mounted to carrier member 50 having optical traces and a splitter 61, optical paths 62, a light collector 63, and light emitters 64,65. Optical assembly 60 further includes housings 66 attached to cover 1 for example by an adhesive or Velcro such as micro Velcro located at attachment areas 67. Rails 66a,66b are slidably received within housings 66 and a detent system is provided to releasably lock carrier member 50 in place as it is adjusted. The detent system, as shown in FIG. 8, can include, for example, ridges 68 formed on rails 66a,66b and corresponding recesses formed on the inside surfaces of housings 66. An operator can linearly move or slide carrier member 50 along direction E to position one of optical assemblies 12,13,14,15 in place and the detent system will releasably hold the carrier member in place.
