DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The following description of various embodiments is merely exemplary in nature and is in no way intended to limit the invention, its applications, or uses.

Referring to FIG. 1, there is shown an illumination apparatus, generally indicated by reference number 10, according to one embodiment of the present invention. As shown in FIG. 1, the illumination apparatus 10 includes a housing 12, at least one light source 14, and a light-altering device 18. The light-altering device 18 is positioned relative to the housing 12 and the light source 14 for receiving and altering light 16 from the light source 14 such that the altered light 28 illuminates at least a portion of the housing 12, such as the upper portion 20 of the housing 12. Alternatively, or additionally, the light-altering device 18 may be positioned relative to the housing 12 and the light source 14 such that the altered light 28 illuminates at least a portion of a surface 50 supporting the illumination apparatus 10, such as a wall, ceiling, floor, tabletop, walkway, clothing, a surface of a mobile platform, etc. During operation, the light-altering device 18 refracts, reflects, diffracts, and/or disperses the light 16 such that the altered light 28 illuminates the portion(s) of the housing 12 and/or the support surface 50 with mood-enhancing light patterns and effects.

In the exemplary embodiment shown in FIGS. 1 through 3, the housing 12 is substantially cube-shaped and decorated to resemble an ice cube or ice berg. It is to be understood, however, that the housing 12 may comprise any of a wide range of other shapes including, but not limited to, fruits, tear drops, rain drops, alphanumeric characters, pyramids, etc. By way of example, and as explained in greater detail below, FIGS. 9 and 10 illustrate apparatus 510 and 610 shaped as the letter “T”.

A wide range of materials may be used for the housing 12 including, but not limited to, acrylics, glasses, plastics, among others. The surfaces of the housing 12 may be transparent, translucent, opaque, reflective, or a combination thereof. In the exemplary embodiment shown in FIGS. 1 through 3, the housing surface 24 positioned opposite the support surface 50 is transparent, whereas the housing side surfaces 26 are translucent or frosted to diffuse or soften the altered light 28.

To allow ready access to the light source 14, the light-altering device 18 and/or the interior of the housing 12, the illumination apparatus 10 further includes a readily removable base assembly 30. The base assembly 30 may be attached to the housing 12 using a suitable fastening system or method (e.g., an interference fit, adhesives, threaded members, resilient ribs, among others). By way of example only, the housing 12 includes an open end 31 sized to be received over and supported by the base assembly 30. Several inwardly extending resilient knobs or protuberances (not shown) are positioned on the housing side surfaces 26 adjacent the open end 31. When the housing 12 is fitted over the base assembly 30, the knobs engage the base assembly 30 to create an interference or friction fit between the housing 12 and the base assembly 30. Alternatively, the base assembly 30 and housing 12 can be formed as a single unit.

Depending on the particular application in which the illumination apparatus 10 is to be used, the illumination apparatus 10 may be configured for placement upon a horizontal support surface, such as a tabletop or desktop. Alternatively, the illumination apparatus 10 can be configured to be mounted on a wall, retrofitted to (e.g., mounted and electrically connected to) an existing wall or ceiling junction box, or attached to a surface of a mobile platform, such as an automobile.

The base assembly 30 further includes a power source 32 switchably connected to the light source 14. In the illustrated embodiment, the power source 32 comprises batteries 36 and an AC adapter port 37 to allow the illumination apparatus 10 to receive power through an electrical cord connected with a standard wall outlet. It should be noted, however, that the power source 32 contemplates any suitable means of providing energy to the light source 14 including, but not limited to, renewable batteries, rechargeable batteries, disposable batteries, and other suitable power sources that may be either external or internal to the illumination apparatus 10. If rechargeable, the power source may be rechargeable by solar, magnetic, electrical, and chemical means, and the like or any combination thereof. Accordingly, the power source mechanism should not be limited to the power source mechanisms described and shown herein.

In the exemplary embodiment of FIG. 1, the base assembly 30 also includes an actuator system for rotating the light-altering device 18 with respect to the light source 14. The actuator system includes a turntable 38 having a transparent support surface for supporting the light-altering device 18. The turntable 38 is coupled to a motor 34 that when energized rotates the turntable 38 and the light-altering device 18 thereon. Alternatively, the actuator system could instead be used to rotate the light source 14 relative to the light-altering device 18.

The light source 14 in the exemplary embodiment 10 comprises a plurality of variously colored light-emitting diodes positioned adjacent an end portion 29 of the light-altering device 18. Alternatively, any suitable light source may be employed including but not limited to fiber optics, halogen, incandescent, laser, fluorescent, magnetic, and the like.

The operation of the light source 14 and the actuator system (i.e., motor 34 and turntable 38) are controlled by a controller in accordance with user input. In one embodiment, the controller includes an integrated circuit/circuit board assembly 40 (i.e., a integrated circuit board mounted on a circuit board) and a switch 42. The switch 42, for example, may allow the user to select from a plurality of predetermined rotational speeds for the turntable 38. Or for example, the switch 42 may allow the user to select from among various display modes for the light source 14. Such display modes may include an off mode, a mode during which the light-emitting diodes blink in a predetermined sequence, and a mode during which the light-emitting diodes pulsate to sounds. The sounds may be produced by the apparatus 10 itself (e.g., via a speaker built-in to the apparatus 10) or a source external to the apparatus 10 (e.g., ambient sounds).

In the illustrated embodiment, the switch 42 comprises a push button switch disposed on a bottom portion 44 of the base assembly 30. However, and depending on the application in which the illumination apparatus 10 will be used, the switch 42 may comprise any one of a wide range of other suitable switch means. For example, the switch 42 may be provided on a cord extending from the base assembly 30. Or for example, the controller may be configured for use with an infrared remote control. In a further embodiment, the switch 42 may be disposed adjacent a lower portion of a flexible surface of the housing 12 such that application of pressure to the flexible surface causes the switch 42 to change setting.

The light-altering device 18 will now be described in more detail. As shown in FIG. 1, the light-altering device 18 is positioned on the turntable 38, which, in turn, is positioned above the light-emitting diodes 14. The light-altering device 18 and the light-emitting diodes 14 are positioned within the housing 12 at a substantially central location relative to the housing 12. The light-altering device 18 alters the light 16 from the light source 14 such that the upper portion 20 of the housing 12 is illuminated with the altered light 28. The altered light 28 is directed upwards through the transparent housing surface 24 and outwards through the translucent housing side surfaces 26, thus providing the room in which the illumination apparatus 10 is being used with mood-enhancing light patterns and effects. Alternatively, the light-altering device and the housing may be integrally formed as a single component. For example, the light-altering device may comprise an internal faceted surface of the housing.

The light-altering device 18 in the exemplary embodiment of FIGS. 1 through 3 comprises facets 46. Although not limited to any particular material, the light-altering device 18 may comprise a transparent material such as polished acrylic material, glass, plastic, crystal, among others. Alternatively, the light-altering device 18 may comprise a translucent or reflective material.

The light-altering device 18 can have a variety of shapes. In the illustrated embodiment, the light-altering device 18 is shaped in a substantially similar manner as the housing 12 (e.g., cube-shaped as in FIGS. 1 and 2, shaped as the letter “T” in FIG. 9). In other embodiments, the light-altering device may be substantially spherical, pyramidal, prismatic, among other shapes depending on the application for which the illumination apparatus 10 will be used.

The illumination apparatus 10 may further include one or more indicia positioned to receive the light 16 from the light source 14 and/or to receive the altered light 28 from the light-altering device 18. The indicia may be at least partially opaque, translucent, or a combination thereof such that the light 16 and/or the altered light 28 produces a silhouette of the indicia that is displayed to a user. The indicia may include any of a wide range of symbols, characters, shapes, words, logos, combinations thereof, etc.

Depending on the particular placement of the indicia, the illumination apparatus 10 may display the silhouette within the housing 12 and/or on a surface external to the housing 12, such as the support surface 50. In exemplary embodiments, the indicia is disposed on an interior surface of the housing 12, suspended within the hollow interior of the housing 12, and/or disposed on an external surface of the light-altering device 18.

In various embodiments of the invention, an illumination apparatus can include a light-altering device that is an integral portion of the housing such that the light-altering device and the housing are monolithically formed as a single component. For example, one embodiment includes a housing having one or more internal faceted surfaces forming the light-altering device.

In any of the various embodiments illustrated in FIGS. 1 through 24, the illumination apparatus can include any suitable means of providing energy to the light sources, such as an AC adapter port to allow the illumination apparatus to receive power through an electrical cord connected with a standard wall outlet, renewable batteries, rechargeable batteries, disposable batteries, power cells, solar cells, watch batteries, and other suitable power sources. If rechargeable, such power sources could be rechargeable by solar, magnetic, electrical, and chemical means, and the like or any combination thereof.

In various embodiments of the invention, an illumination apparatus can include one or more indicia that are highlighted (e.g., illuminated, backlit, etc.) by light from a light source. This indicia can include a wide range of graphic images, graphic elements, graphic images, designs, artwork, distinctive marks, identifying symbols, company logos, company contact information, text, alphanumeric characters, advertisements, trademarks, trade names, service marks, sports teams insignias, names, monograms, photographs, among others.

Various embodiments include a light-altering material having indicia configured to receive light from the light source such that the light produces a representation of the indicia onto a surface external to and adjacent the illumination apparatus. In one particular embodiment, an illumination apparatus includes LEDs that are positioned about one-fourth inch from a bottom surface of the illumination apparatus. The LEDs are positioned to direct light at a generally downward angle towards indicia provided (e.g., etched, marked onto, etc.) onto a light-altering material (e.g., acetate, etc.). The indicia can be distorted such the indicia appears clear and undistorted when projected onto the support surface. By way of example only, the light-altering material 818, 1018 in FIGS. 13 and 18, respectively, may include indicia spaced around the outer perimeter such that when the LEDs 814, 1014 are activated, the light projects the indicia onto the support surface generally around but a spaced-distance away from the housing's outer perimeter 854, 1054. This can have particular commercial appeal for advertising such as when the indicia forms a company logo or other advertisement.

In any of the various embodiments illustrated in FIGS. 1 through 24, the illumination apparatus can be configured for use as a portable accessory item. In addition, the illumination apparatus can also include one or more user attachment devices (e.g., adhesives, clips, magnets, pins, other suitable attachment devices, etc.) for attaching the illumination apparatus to a user, for example to allow the illumination apparatus to be used as jewelry, a hair ornament, an illuminating sticker, among other accessory items.

The switch may, for example, allow the user to select from among various display modes for the light sources, such as an off-light mode, an on-light mode, a mode in which each of the light sources simultaneously emit steady or non-flashing light, a mode in which the light sources emit light intermittently, a mode in which the various light sources illuminate or blink at different times in accordance with a predetermined sequence or order, a mode in which the light sources emit light that phases between or blends colors, a mode in which the light sources emit light randomly, a mode in which the light sources pulsate to sounds, and/or a mode combining one or more of the foregoing. Such sounds may be produced by the illumination apparatus itself (e.g., via a speaker built-in to the illumination apparatus) or a source external to the illumination apparatus (e.g., ambient sounds). In some embodiments, sounds can cause synchronized pulsation of the light sources of two or more different illumination apparatus, thus providing a pleasing light pattern or effect.

The controller can also include a plurality of switches each of which can be used to control the operation of an individual light source or group of light sources. For example, the controller may include a first switch for activating and deactivating LEDs that emit white light, and a second switch for activating and deactivating the LEDs that emit blue light.

Additionally, an illumination apparatus of the present invention can include a push-button switch for switchably connecting the light source to the power source. The switch can be positioned within the illumination apparatus and be coupled to an externally flexible surface portion of the illumination apparatus such that application of external pressure upon the externally flexible surface portion activates the switch, thereby causing operation of the light source. The external pressure may, for example, be applied by the user squeezing the illumination apparatus at the externally flexible surface portion. The switch may also allow the user to cycle through various display modes or select a particular color for the light by successively squeezing the illumination apparatus at about the externally flexible surface portion. Additionally, the switch may also allow the user to dim or brighten the intensity of the light, for example, by holding down the switch with continuously applied pressure to the illumination apparatus at about the externally flexible surface portion.

Alternatively, an illumination apparatus can include other suitable switching means. For example, the switch may be provided on a cord extending from an illumination apparatus. Or for example, an illumination apparatus may include a controller configured for use with an infrared remote control. As yet another example, an illumination apparatus can include electrical terminals for switchably connecting the light source to the power source. For example, the electrical terminals can be located such that a user's hand upon grasping the item completes the circuit for power delivery to the light source from the power source.
