DETAILED DESCRIPTION

(9) FIG. 1 is a side view of an example light assembly 100, arranged in accordance with at least some embodiments of the present disclosure. The light assembly 100 includes an arm 110 and a lighting control unit 120. The arm 110 includes a frame 111, a first hinge 112, a second hinge 114, and a light source 116. Some examples of the light source 116 include, without limitation, a light-emitting diode (LED) lamp, a halogen lamp, an incandescent light bulb, and others. The lighting control unit 120 includes at least a base 121 and a cover 123, together forming an enclosure. The cover 123 also includes a light blender 127 and a power button 129. In some embodiments, the light blender 127 may include multiple components, which will be further described in subsequent paragraphs and in junction with FIG. 4.

(10) In some embodiments, the first hinge 112 and the second hinge 114 may be strips of a bendable and magnetic material, so that the hinges can be attracted to magnets. For example, the strips may be made of galvanized iron. Also, the first hinge 112 and the second hinge 114 may correspond to two ends of a single strip (as shown in FIG. 3A). Alternatively, the first hinge 112 and the second hinge 114 may correspond to physically separate strips. Details of the hinge movement will be further described in subsequent paragraphs and in junction with FIG. 3.

(11) The frame 111, which includes a first joint 117 and a second joint 119, is configured to bend or straighten at the two joints.

(12) In some embodiments, the light source 116 may be configured to electrically connect to a power source through a wired connection (not shown) in the frame 111. The wired connection may be placed in the base 121. Some examples of the power source include, without limitation, alternative current (AC) power supply, batteries, and others. Alternatively, the light source 116 may be configured to electrically and wirelessly connect to a power source. The power source may be external to the light assembly 100 (e.g., AC wall socket) or inside the lighting control unit 120 (e.g., batteries).

(13) In some embodiments, the cover 123 can be rotated in either a counterclockwise direction or a clockwise direction as represented by an arrow 125. The rotation of the cover 123 may occur while the base 121 remains stationary. When the arm 110 is coupled to the cover 123, the rotation of the cover 123 and the rotation of the arm 110 and the light source 116 would occur in tandem.

(14) FIG. 2A and 2B illustrate some alternative configurations of the arm 110, arranged in accordance with at least some embodiments of the present disclosure. In FIG. 2A, the arm 110 is shown to mount on a wall 210 and may be movable between, for example, a first position 212 and a second position 214. In FIG. 2B, the arm 110 is shown to couple to a floor-standing base 230. Any technically feasible mechanism may be employed to attach the arm 110 to the wall 210 and the floor-standing base 230.

(15) In alternative embodiments, the lighting control unit 120 may not be coupled to the arm 110. For example, the lighting control unit 120 may be mounted on a wall structure and may be used to control ambient lighting in a room. The lighting control unit 120 may also come in other shapes, such as a square, a rectangle, and others.

(16) FIG. 3A is an exploded view of an example arm of a light assembly, arranged in accordance with some embodiments of the present disclosure. The example arm shown in FIG. 3A corresponds to the arm 110 illustrated in FIG. 1. The frame 111 includes three separate sections, which are connected by the first joint 117 and the second joint 119. A first section of the frame 111, located near one end of the frame, includes a first sleeve 340, which is configured to receive a first hinge support 313. Similarly, a second section of the frame 111, located near the other end of the frame, includes a second sleeve 341, which is configured to receive a second hinge support 315.

(17) In some embodiments, the first hinge support 313 and the second hinge support 315 may be inserted into the first sleeve 340 and the second sleeve 341, respectively. To provide stability to the light assembly, the first hinge support 313 may be heavier than the second hinge support 315. The width of the first hinge support 313 may be greater than the width of the first sleeve 340. Therefore, after inserting the first hinge support 313 into the first sleeve 340, the first hinge support 313 may be secured to the first sleeve 340. Similarly, the width of the second hinge support 315 may also be greater than the width of the second sleeve 341 so that the second hinge support 315 may be secured to the second sleeve 341 after the insertion of the support into the sleeve.

(18) In some embodiments, a first magnet 330 may be directly coupled to the first hinge support 313, and a second magnet 331 may be directly coupled to the second hinge support 315. Alternatively, if the first hinge 112 and the second hinge 114 are made of a material that responds weakly to the first magnet 330 and the second magnet 331 (e.g., a material with heavy coating), respectively, the first magnet 330 and the second magnet 331 may be enclosed in a first case 320 and a second case 321, respectively. The first case 320, which is mounted on the first hinge support 313, and the second case 321, which is mounted on the second hinge support 315, may be made of a ferromagnetic material, such as, without limitation, galvanized iron.

(19) In some embodiments, the first hinge 112 is configured to be in contact with the first magnet 330, and the second hinge 114 is configured to be in contact with the second magnet 331 to take advantage of the magnetic force. The first hinge 112 includes a first hook 350 at one end of the first hinge 112. The first hinge 112 is configured to move in a first groove 310, a confined space defined by the sleeve 340 and the first hinge support 313, between a first end 360 and a second end 370 of the first groove 310. Similarly, the second hinge 114 also includes a second hook 351 at one end of the second hinge 114. The second hinge 114 is configured to move in a second groove 311, a confined space defined by the sleeve 341 and the second hinge support 315, between a first end 361 and a second end 371 of the second groove 311.

(20) FIGS. 3B, 3C, and 3D are side views of an example light assembly in different positions to illustrate the movement of its hinges, arranged in accordance with some embodiments of the present disclosure. In conjunction with FIG. 3A, in FIG. 3B, the frame 111, the first hinge support 313, and the second hinge support 315 remain in a substantially straight line position. In this position, the first hook 350 of the first hinge 112 is at the first end 360 of the first groove 310, and the second hook 351 of the second hinge 114 is at the second end 371 of the second groove 311.

(21) In conjunction with FIG. 3A, in FIG. 3C, the frame 111 bends in relation to the lighting control unit 120. As a result of the bending motion, the first hook 350 of the first hinge 112 moves from the first end 360 towards to the second end 370 of the first groove 310. The frame 111 will not be able to bend any further at the joint 117 once the first hook 350 reaches the second end 370.

(22) In conjunction with FIG. 3A, in FIG. 3D, the light source 116 bends in relation to the frame 111. As a result of the bending motion, the second hook 351 of the second hinge 114 moves from the second end 371 towards the first end 361 of the second groove 311. The light source 116 will not be able to bend any further at the joint 119 once the second hook 351 reaches the first end 361.

(23) FIG. 4 is an exploded view of an example lighting control unit of a light assembly, arranged in accordance with some embodiments of the present disclosure. The example lighting control unit shown in FIG. 4 corresponds to the lighting control unit 120 illustrated in FIG. 1.

(24) In some embodiments, the lighting control unit 120 includes the cover 123 and the base 121. An anti-skit pad 490 may be attached to the base 121. As shown in FIG. 4, the cover 123 and the base 121 form the enclosure, which houses at least a disc 440, a power circuit board 520, a first plate 401, a shim 450, a second plate 402, the light blender 127 of FIG. 1, which may include a position-to-signal converter 610 and a position generator 460.

(25) The first plate 401 complements a second plate 402. The first plate 401 defines a first opening 410, a first channel 420, and a second channel 430. The second plate 402 includes a cylindrical rod (not shown here but shown in FIG. 6A) configured to engage with the first opening 410 and a disc 440, so that the second plate 402 can rotate in relation to the first plate 401, and the first plate 401 and the second plate 402 can be held together. Subsequent paragraphs will provide additional details of the relationships among the first plate 401, the second plate 402, and the disc 440. The disc 440 may be made of a soft or elastic material, for example, rubber, plastic, and others. The shim 450 is configured to be disposed in the second channel 430.

(26) In some embodiments, the power circuit board 520 may be disposed on one side of the first plate 401, and the position-to-signal converter 610 may be mounted on one side of the second plate 402. The power circuit board 520 is electrically connected to a power source of the light assembly and is configured to regulate the current for the light source 116. The position-to-signal converter 610, coupled to the position generator 460, is configured to influence various lighting parameters, such as, without limitation, brightness and correlated color temperature of the light source 116. Subsequent paragraphs will provide additional details for the position-to-signal converter 610.

(27) FIG. 5A is top view of the first plate 401 of the lighting control unit 120, arranged in accordance with some embodiments of the present disclosure. In conjunction with FIG. 4, the shim 450 may be disposed in the second channel 430 on a top side of the first plate 401 to decrease the friction between the first plate 401 and the second plate 402. The shim 450 may be made of a soft or elastic material, for example, rubber, plastic, and others. In some embodiments, the first plate 401 may have a circular region 550, which defines the first opening 410.

(28) FIG. 5B is bottom view of the first plate 401 of the lighting control unit 120, arranged in accordance with some embodiments of the present disclosure. In conjunction with FIG. 4, the power circuit board 520 may be disposed on a bottom side of the first plate 401, and the power circuit board 520 may include an AC/DC port 530 and a USB port 540. Any wiring coupled to the power circuit board 520 may come through the first opening 410. As shown, the thickness of the circular region 550 is less than the thickness of the outer rim of the first plate 401.

(29) FIG. 6A is a bottom view of the second plate 402 of the lighting control unit 120, arranged in accordance with some embodiments of the present disclosure. In some embodiments, the second plate 402 includes a stud 412 and a cylindrical rod 411. In conjunction with FIG. 4 and FIG. 5A, the stud 412 is configured to be disposed in the first channel 420 of the first plate 401. The stud 412 may move along the first channel 420 to facilitate the rotation between the first plate 401 and the second plate 402. The cylindrical rod 411 may be hollow, and when the cylindrical rod 411 is inserted through the first opening 410 of the first plate 401, a path 620 through the first plate 401 and the second plate 402 can be defined.

(30) For the second plate 402 to rotate while remaining coupled to the first plate 401, in some embodiments, in conjunction with FIG. 4, the disc 440 may be disposed on the bottom side of the first plate 401, with its protrusion 441 inserted in the path 620. To hold the first plate 401 and the second plate 402 together, in conjunction with FIG. 4, the disc 440 may have four holes that match the four holes on the cylindrical rod 411 as shown in FIG. 6A, and with the protrusion 441 inserted in the path 620, the disc 440 may be secured to the cylindrical rod 411 with screws through the four holes.

(31) To enable a smooth rotation motion between the first plate 401 and the second plate 402, in some embodiments, the height of the cylindrical rod 411 is greater than the thickness of the circular region 550. To illustrate, in conjunction with FIG. 5A and FIG. 6A, after inserting the cylindrical rod 411 through the first opening 410 so that the complementary first plate 401 and the second plate 402 are coupled, a portion of the cylindrical rod 411 would extend above the surface of the circular region 550. Thus, when the disc 440 is secured on the cylindrical rod 411, the disc 440 is not in contact with the surface of the circular region 550. Without this physical contact, the second plate 402 could rotate about the cylindrical rod 411 as an axis smoothly.

(32) FIG. 6B is a top view of the second plate 402 of the lighting control unit 120, arranged in accordance with some embodiments of the present disclosure. In FIG. 6B, the position-to-signal converter 610 is configured to blend the brightness and the correlated color temperature (CCT) of the light source 116. In some embodiments, the position-to-signal converter 610 includes a control circuit board 611 and a plurality of variable resistors 612. In conjunction with FIG. 4, the position-to-signal converter 610 is coupled to the position generator 460. The illustrated position generator 460 includes tracks 471, which are configured to engage with hinge supports 613 and 614 of the variable resistors. Thus, in response to finger movement of a user touching the position generator 460, the movements of the position generator 460 may change the positions of the hinge supports 613 and 614. For example, in response to a movement along the longitudinal direction by the light blender, the hinge supports 613 may change their positions along the longitudinal direction while the hinge supports 614 remain still. In response to another movement along the transverse direction by the light blender, the hinge supports 614 may change their positions along the transverse direction while the hinge supports 613 remain still.

(33) In some embodiments, the control circuit board 611 may be configured to generate a first control signal to control one lighting parameter (e.g., the brightness) of the light source 116 based on the positions of the hinge supports 613 and generate a second control signal to control another lighting parameter (e.g., the CCT) of the same light source 116 based on the positions of the hinge supports 614. By modifying multiple lighting parameters, the effect of blending brightness and lighting temperature is enhanced. The control circuit board 611 may be electrically connected to the light source 116 via a wired connection, which passes through the first opening 410 and the path 620. In response to the first control signal and the second control signal, the light source 116 may change multiple lighting parameters, such as the brightness and CCT, at the same time. Alternatively, the generated control signals are sent to the power circuit board 520, and the output of the power circuit board 520 is adjusted based on the control signals before delivering to the light source 116.

(34) In alternative embodiments, the position generator 460 is free of the tracks 471. The position generator 460 may correspond to a computer mouse or a touchscreen, wherein the various positions generated by the moving the computer mouse or touching different parts of the touchscreen may be used by the position-to-signal converter 610 to generate control signals to blend the brightness, CCT, and other lighting parameters.

(35) While the forgoing is directed to embodiments of the present disclosure, other and further embodiments of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claim that follow.
