1A-1D depict an apparatus for simulating an open candle flame according to certain embodiments. The device 100 includes a flame display 101, an upper housing 102, a lower housing 103, a lens 104, a Light Emitting Diode (LED)105, a lamp socket 106, a weight 107, two first swing joints 108a, 108b, two second swing joints 109a, 109b, a coil 110, a battery case 111, a link 112, a swing holder 113, and a Printed Circuit Board (PCB) 114.
The flame display 101 is illuminated by an LED 105 through a lens 104. The LED 105 and lens 104 are located within the lamp base 106. One end of the link 112 is connected to the flame display 101, and the other end of the link 112 is connected to the weight 107. The first swing joints 108a, 108b are located on opposite lateral sides of the link 112 along a first axis to form a first pivot structure, and the second swing joints 109a, 109b are located on opposite lateral sides of the swing holder 113 along a second axis to form a second pivot structure, respectively.
The first swing joint 108a includes a lever protrusion 117a of the link 112 and a retainer slot 115a of the swing retainer 113, the lever protrusion 117a being attached to a lateral side of the link 112 along a first axis, and the retainer slot 115a being located on the lateral side of the swing retainer 113 along the first axis. The first swing joint 108b includes a lever protrusion 117b of the link 112 and a retainer groove 115b of the swing retainer 113, the lever protrusion 117b being attached to the other lateral side of the link 112 along the first axis, the retainer groove 115b being located at the other lateral side of the swing retainer 113 along the first axis.
The second swing joint 109a includes: a holder protrusion 118a of the swing holder 113 and a housing groove 116a of the lower housing 103, the holder protrusion 118a being mounted on the lateral side of the swing holder 113 along the second axis, and the housing groove 116a being located on the lateral side of the lower housing 103 along the second axis. The second swing joint 109b includes a holder protrusion 118b of the swing holder 113 and a housing groove 116b of the lower housing 103, the holder protrusion 118b is attached to the other lateral side of the swing holder 113 along the second axis, and the housing groove 116a is located on the other lateral side of the lower housing 103.
In this embodiment, the housing slots 116a, 116b are located on the top edge of the lower housing 103 and are closed by the bottom edge of the upper housing 102, which may prevent the retainer tabs 118a, 118b from disengaging to secure the swing retainer 113 in place.
In this embodiment, the upper housing 102 and the lower housing 103 are connected by a pin and socket arrangement 120, the pin and socket arrangement 120 including a small pin 122 and socket 123 (as shown in the inset of FIG. 1B), which allows assembly without glue, thereby reducing the assembly effort. In certain embodiments, such a peg and socket structure 120 may also be used to align the PCB and coil with the pendulum structure, and the peg structure may be adapted to have different dimensions to support candles of different sizes.
In this embodiment, the lamp socket 106 is located between the upper housing 102 and the lower housing to facilitate assembly of the device 100.
As shown in fig. 1A and 1B, the upper housing 102 has a top hole 119, a first width of the top hole 119 being large enough to allow the flame display 101 to pass through the top hole 119 during assembly of the upper housing 102 to the lower housing 103, and the top hole 119 having a second width being small enough to prevent the first pivot structure and/or the weight 107 from passing through the top hole 119 after the upper housing 102 is assembled to its final position by rotation. For example, during assembly, the upper housing 102 is rotated 90 ° from its final position to allow the flame display 101 to pass through. This locks the first pivot structure and counterweight 107 within the upper and lower housings 102, 103 once the upper housing 102 is rotated and positioned to its final position, and prevents the flame display 101 from being removed from the upper housing 102 even if the first pivot structure is released from its latched position.
Magnets (not shown in fig. 1A-1D) are attached to the bottom of the counterweight 107 and are located between the counterweight 107 and the coil 110. The coil 110 is electrically connected to a PCB 114 with a driver for generating a current to the coil 110 for generating an electromagnetic field.
When a current provided by the PCB 114 passes through the coil 110, an electromagnetic field is generated. The weight 107 swings due to the interaction between the electromagnetic field from the coil 110 and the magnetic field from the magnet. In view of the first and second pivot structures, the flame display 101 swings with the counterweight 107 along the first and second axes under the leverage of the link 112, as shown in fig. 1C. With this actuation arrangement, the swinging of the flame display 101 is more pronounced. Fig. 1D shows the device 100 further comprising a housing 121. The housing 121 may comprise wax, plastic, glass, resin, ceramic, metal, fabric, paper, wood, silicone, or any other material. Fig. 2 is a schematic diagram illustrating a pendulum structure of an apparatus according to some embodiments. The balance weight 21 is cylindrical, and upper and lower edges of the balance weight 21 are chamfered. A cylindrical permanent magnet 22 is attached to the bottom end of the counterweight 21 along the vertical axis of the counterweight 21 and is partially enclosed within a bore 24 of the counterweight 21. The link 23 is attached to the top end of the counterweight 21. The counterweight 21 is suspended on the first pivot structure 25 so as to be swingable.
Fig. 3A and 3B depict the swing mechanism of the device as the flame display swings about the first axis and the second axis. Two first swing joints 31a, 31b are located on lateral sides of the connecting rod 30 opposite along the first axis to form a first pivot structure. The first swing joint 31a includes a lever protrusion 36a of the link 30 and a holder groove 33a of the swing holder 32. The first swing joint 31b includes a lever protrusion 36b of the link 30 and a holder groove 33b of the swing holder 32. The swing holder 32 has a hole in the middle for accommodating the link 30. The flame display 34 oscillates about a first axis and a second axis under the influence of the electromagnetic field generated by the coil.
In this embodiment, the retainer slot 33a has a width opening that is slightly smaller than the rod protrusion 36a so that the pendulum structure, along with the flame display 34, can be snapped into place on the pendulum retainer 32. The snap fit provides for ease of assembly while also preventing the flame indicator 34 from disengaging from the first pivot structure. Similarly, retainer slot 33B has a width opening (not shown in fig. 3A and 3B) that is slightly smaller than stem protrusion 36a to provide the same function.
In this embodiment, the lever projection 36a has an edge 38a, and the edge 38a contacts the retainer slot 33a to provide a point contact between the retainer slot 33a and the lever projection 36a in the first pivot structure, thereby providing a very low friction mechanism, allowing the pendulum structure to move freely and be easily assembled. Similarly, the lever projection 36B also has an edge (not shown in fig. 3A and 3B) to provide the same function.
Two second swing joints 35a, 35b are oppositely located on the lateral sides of the swing holder 32 along the second axis to form a second pivot structure. The second swing joint 35a includes a holder protrusion 37a of the swing holder 32 and a housing groove of the housing (not shown in fig. 3A and 3B). The second swing joint 35B includes a holder protrusion 37B of the swing holder 32 and another housing groove of the housing (not shown in fig. 3A and 3B). The axes of the two second pivot joints 35a, 35b are perpendicular to the axes of the two first pivot joints 31a, 31 b. Under the influence of the electromagnetic field generated from the coil, the swing holder 32 rotates about the second axis, while applying a force to the two first swing joints 31a, 31b to drive the link 30 to rotate about the second axis. In combination with the first and second pivot structures, the flame display 34 may be substantially oscillated about the first and second axes.
In this embodiment, the retainer projection 37a has an edge 39a for contacting the housing slot to provide point contact between the housing slot and the retainer projection 36 a. Similarly, the holder protrusion 37b also has an edge 39b to provide the same function.
In some embodiments, all of the first and second pivot structures are made using simple plastic parts, thereby eliminating the need for metal shafts, which may reduce material costs and assembly steps. In certain embodiments, the flame display and pendulum structure are all molded as one piece, and can be easily assembled by rotating to pass through the aperture of the pendulum holder. Once the flame display and pendulum structure are secured in place to the pendulum holder, the flame display and pendulum structure are prevented from loosening from the housing.
Fig. 4A and 4B show an illumination module 40 comprising a lamp holder 41, an LED 42 and a lens 43. The LED 42 and the lens 43 are accommodated in the lamp holder 41.
Fig. 5A and 5B depict a lighting module 50, which lighting module 50 comprises a lamp holder 51, an LED 52 and a lens 53. The LED 52 and the lens 53 are accommodated in the lamp holder 51. The lamp holder 51 has a bend 54 for facilitating attachment of the illumination module 50 to the device and for facilitating illumination of the flame display.
Fig. 6A and 6B depict an apparatus 600 for simulating an open candle flame, according to some embodiments. Apparatus 600 includes chamfered cylinder weight 610, coil 620, PCB 630 and cylindrical magnet 640. Beveled cylinder weight 610 has a hole at the bottom of beveled cylinder weight 610. A cylindrical magnet 640 is attached to the bore. The coil 620 is located below the cylindrical magnet 640 with an offset distance between the center of the coil 620 and the vertical axis of the cylindrical magnet 640.
Fig. 7A-7H depict an apparatus 700 having simulated open candle flames utilizing a self-luminous flame display, according to some embodiments. The device 700 includes a self-luminous flame display 701, an upper housing 702, a lower housing 703, a linkage 704, a swing holder 705, a weight 706, a magnet 707 (as shown in fig. 7E), a coil 708, a PCB 709, a battery compartment 710, and a housing 716.
The self-luminous flame display 701 includes a flame housing 711 and an LED 712. The flame housing 711 and the LED 712 are attached to the top end of the connecting rod 704, so a light projection module is not required in an embodiment.
As shown in fig. 7F, the wobble retainer 705 includes two spiral-shaped retainer grooves 713 for engaging with the two rod protrusions 714 of the link 704, respectively. The helical retainer groove 713 has an opening 715 with a width slightly less than the width of the lever projection 714 to secure the lever projection 714 within the helical retainer groove 713 to prevent the pivot structure from disengaging from its detent position. This also facilitates assembly between the rod protrusion 714 and the helical retainer groove 713 by snapping the rod protrusion 714 into the helical retainer groove 713 via the opening 715.
Thus, it can be seen that an improved device for simulating an open candle flame has been disclosed which eliminates or at least reduces the disadvantages and problems associated with prior art devices. The swing mechanism of the device minimizes cost and parts count, eases organization and simplifies assembly, and ensures that the flame display remains in place after manufacture and during shipping and handling.
