Decorative lighting apparatus

Abstract

A decorative light apparatus has a housing 12, a dome 20, a power supply, a motor 30, a light board 36 having LEDs 46 surrounding the motor, a multi-surface refractive lens and a beam-splitter lens light shade. The light disk 36 supports the motor 30 directly so that alignment of the LEDs, lens and motor are always correct. The motor may further transmit vibrations into the light board which can provide a slight shimmering effect of the light passing through the lens.

DETAILED DESCRIPTION

(11) FIG. 1 shows a decorative light system 10 with a housing 12, an optional pivoting mounting bracket 14 and an optional removable ground stake 16. At the distal end of the housing is a protective ball dome which is affixed thereto.

(12) FIG. 2 shows some of the inner construction of the light system 10.

(13) Electric motor 30 is mounted removably in the housing. Motor shaft 34 extends orthogonally from the motor to a distal end. A light altering disk or multi-refracting lens 38 is affixed to the shaft toward the distal end. The disk may have facets on one or both faces and may also be proximal to the motor.

(14) In this embodiment, there is a non-rotating fixed light board 36. The board has a central for mounting of the motor thereon, with a plurality of lighting elements 46 (typically LEDs concentrically surrounding the motor shaft and motor, see FIGS. 5, 6, 7). This configuration has the advantage of providing perfect alignment of the motor shaft and LEDs since they are both fixed on the board at time of manufacture.

(15) The light altering dome 20 may be faceted or frosted in many different methods, with one such method seen in FIG. 2 to enhance light scatter or non-faceted as shown in FIG. 1.

(16) FIG. 3 shows one possible pattern of the light altering disk 38 beneath dome 20.

(17) FIGS. 4 and 5 show the housing interior from other angles.

(18) FIGS. 6 and 7 show an embodiment of a light board 36 relative to the light altering disk 38 and motor 30, with FIG. 7 being an alternative embodiment.

(19) The light board is preferably a circuit board with a plurality of LEDs 46, (discrete or chips with circuit board (PCB) mounting), arranged circumferentially, at least around the aperture 40 which allows for mounting of the motor directly thereon. FIG. 6 shows motor 30 affixed to board 36 and surrounded by LEDs 46. Shaft 34 is attached to disk 38. The number of LEDs 46 may vary based on application and light color combinations.

(20) Because the motor is mounted directly on the light board, it is possible to create special effects from the vibration in the motor if desired. For example, the light board can be loosely mounted in the housing such as by rubber bushings so that vibrations in the motor cause are more easily transmitted to the light board. Any movement of the light board is amplified as a shimmer effect as light passes through the light altering lens (such as diffraction or prism lens). This shimmer can be further enhanced by having an unbalanced motor shaft or by using the controller to rapidly stop and start the motor or rapidly reverse motor direction.

(21) In an alternate embodiment, the motor is eliminated entirely and the LEDs themselves are driven by a controller which illuminates the LEDs in predetermined sequences and color combinations to create interesting light patterns after the light passes through disk 38, where disk 38 can be a separate disk as shown, or can be located/mounted on the bottom of dome 20.

(22) In a FIG. 7, the motor is positioned on the LED light board, in this case with an off center shaft, it may also be on-center.

(23) In a further embodiment, not shown, motor 30 may be positioned in the center of the aperture 40 of light board 36 with LEDs 46 located around the aperture 40 and light altering disk 38 mounted atop shaft 34. In such case the body of the motor is straddling the light board with part above and part below the board.

(24) An alternative version of the motor 30 is possible which has a central shaft 34 and which is centrally mounted on the board 36. In this version, there are three LEDs, which are controllable (color/intensity/pulse frequency) by the controller in the housing or elsewhere. The three LEDs can be configured to produce as much light as the eight LEDs in FIG. 6.

(25) The motor can be a gear reduction motor (typically off set shaft) or direct drive DC stepper motor with or without gear reduction. It is also possible to combine this with a central drive motor and a set of several (for example 8) LEDs concentrically around the shaft. A stepper motor will also impart more shimmer into the LEDs due to its stop-start action at each step.

(26) FIGS. 8, 9 and 10 illustrate alternate embodiments of a dome 20A which is intended to rotate to create special lighting effects.

(27) FIG. 8 shows multiple embodiments simultaneous but in the preferred embodiment, motor 30 and lens 38 would be deleted in favor of motor 54 and faceted dome 20A.

(28) In this embodiment, the motor 54 is offset from the central axis of the housing (which would correspond to shaft 34). In this case, the motor is close to the housing edge so that a portion of the gear 56 extends adjacent to the inner periphery of the housing. The circuit board 36 holding the LEDs is cut out in a semicircular pattern to accommodate the motor. Motor 54 includes a drive gear 56 with teeth. The dome 20A includes a ring gear on its inner periphery close to the distal edge of the dome.

(29) In the preferred embodiment, the dome 20A has a planar flange surface 60 at its distal end. Gear teeth 58 are adjacent to the flange but on the inside of the dome. Their exact location is dictated by the requirement they can mesh with gear 56. The housing 12 also has a planar circumferential surface upon which the flange surface 60 slideably engages so that when drive motor 54 rotates gear 56, ring gear 58 is engaged and the dome rotates. Coupling 52 (FIG. 8) maintains the dome is engaged with the housing but not too tightly as to prevent the dome from rotating. The coupling can be a band which engages the planar surface or it may have a screw thread to engage a like thread on the housing or dome.

(30) The housing shown has a stake but it could be a tapered housing terminating in an Edison light socket, or similar, so it can be screwed directly into a lamp.
