While the invention will be described in reference to these embodiments, it will be understood that they are not intended to limit the invention. To the contrary, the invention is intended to cover alternatives, modifications, and equivalents that are included within the spirit and scope of the invention. In the following disclosure, specific details are given to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without all of the specific details provided.

[0049] The present invention concerns a special effects device 100 which may comprise a plurality of combustion simulating elements 110, each having a light-emitting device 120; a sleeve 130 for holding the plurality of combustion-simulating elements 110 in first positions (see, e.g., FIG. 1A); an actuator 140 for protruding the combustion-simulating elements 110 out of the sleeve 130 and into second positions (see, e.g., FIG. 1B), wherein the light-emitting devices 120 are more spatially dispersed than in the first positions; and a controller 150 for controlling the light-emitting devices 120 and the actuator 140. In some embodiments, the special effects device 100 may further comprise at least one static light-emitting device 125 positioned at the end of the sleeve 130.

[0050] As seen in FIG. 1A, the present invention may comprise a plurality of combustion simulating elements 110, each comprising an arm 111 with a first end 113 and a second end 112, the second end 112 comprising the light-emitting device 120, and the first end 113 comprising a connection 114 to an extension member 141 of the actuator 140. The arms 111 of the plurality of combustion simulating elements may comprise lengths in a range, e.g., from about 10 inches to about 48 inches, wherein each arm 111 may comprise a different length. In some embodiments, the arms 111 may comprise a resilient material which is operable to retain a curved shape when not inside the sleeve 130 (e.g., in the second position, see FIG. 1B), and which is flexible enough to conform to a straightened shape when inside the sleeve 130 (e.g., in the first position, see FIG. 1A). The curved shape may comprise a substantially parabolic shape which approximates the path of a spark expelled in a substantially vertical or near-vertical direction from an explosion.

[0051] The special effects device 100 may be used in combination with a combustion effect system 160, the combustion effect system 160 comprising a display 162 (e.g., a monitor) for showing a visual effect, and an audio emitter 163 (e.g., a speaker) for sounding an audio effect. In other embodiments, the special effects device 100 may be used in combination with other light effects (e.g., simulating an explosion, fire, or other combustion effect).

[0052] The light-emitting device 120 may comprise a light-emitting diode and may be operable to emit light of a first color and first intensity and then switch to emitting light of a second color and/or second intensity. The controller 150 may be operable to change the emitted light color and/or intensity of light-emitting device 120 as a function of a predetermined parameter, such as time after actuation (e.g., causing the extension member 141 to extend toward the sleeve 130), or depending on the distance traveled from the first position to the second position.

[0053] The sleeve 130 may comprise a rigid, substantially cylindrical shape defining a channel 131, and having a first end 133 and a second end 132. The second end 132 may be distal in relation to the actuator 140 and may comprise an opening through which the first ends 112 of the combustion simulating elements 110 emerge upon actuation, and the first end 133 may be proximal to the actuator 140. The channel 131 may comprise an inner diameter chosen to allow the plurality of combustion simulating elements 110 to pass through the channel rapidly and without becoming tangled. The sleeve 130 may comprise any rigid material of sufficient strength to support the combustion simulating elements as they move in and out of the sleeve 130 and resist damage from operation of the special effects device 100.

[0054] The static light-emitting device 125 may comprise a plurality of light-emitting diodes arranged in a row around a portion of the circumference of the second end 132 of the sleeve 130, such that light emitted from the static light-emitting device 125 may simulate a combustion source or ignition point (e.g., an ember, or an electric arc) for the sparks simulated by the combustion simulating elements 120. The static light-emitting device 125 may be operable to emit light of a first color and first intensity and switch to emitting light of a second color and/or second intensity as a function of time prior to actuation.

[0055] The actuator 140 may comprise any mechanism operable to cause the combustion simulation elements to quickly move from a first position (e.g., inside the sleeve, see FIG. 1A) to a second position (e.g., outside the sleeve, see FIG. 1B). The actuator 140 may comprise an extension member 141 which is mechanically extended by the action (e.g., electric actuation) of the actuator 140. The actuator 140 may be in electronic communication with the controller 150. The extension member 141 may comprise a rod mechanically attached via a rigid band 114 at the first ends 113 of a bundle of combustion simulation elements 110, the rod 141 being operable to push the first ends 113 toward the second end 132 of the sleeve 130. The actuator 140 may comprise a predetermined stroke length (e.g., the length to which the extension member is extended), such that the first ends 112 of the combustion simulating elements 110 are extended out of the sleeve 130 to predetermined lengths.

[0056] The controller 150 may comprise any system operable to initiate the actuator 140 and control the light-emitting devices 120 (e.g., light up upon actuation, change color and/or intensity as a function of time or position, and shut off prior to being retracted back to the first position) and static light-emitting devices 125 (e.g., light up prior to actuation, change color and/or intensity as a function of time, and shut off upon actuation). In some embodiments, the controller may comprise a switchboard having at least a first toggle switch 151 for causing actuation and a first dial 152 for controlling the intensity of the light-emitting devices 120, and a second toggle switch 153 for initiating the lighting of the static light-emitting device 125 and a second dial 153 for controlling the intensity of the static light-emitting device 125.

[0057] In other embodiments, the controller may be operable to connect with a central control system, e.g., a general purpose computer having software operable to run controllers of multiple effects devices. The central control system may be in electronic communication with the controller for light-emitting devices 120 and the actuator 140. The central control system may provide activation signals to the controller for the light-emitting devices 120 and the actuator 140 via wired or wireless signal. The central control system may be additionally in electronic communication with one or more additional special or theatrical effect devices. In some embodiments central control system may transmit data in an industry standard format, e.g. Digital MultipleX (DMX) format, to the controller for light-emitting devices 120 and the actuator 140 and the controllers for other effect devices. The central control system may be operable and have programming that coordinates different combustion effect devices to create a coordinated realistic overall effect that simulates, e.g., an explosion, canon fire, etc.

[0058] In another embodiment, as seen in FIGS. 2A-2D, the special effects device 200 may comprise a sleeve 230 defining a channel 231 operable to house at least a portion of the arms 211 of a plurality of combustion simulating elements 210. The sleeve 230 may have a first end 232 and a second end 233, the second end 233 comprising a static light-emitting device 225 (e.g., a plurality of light emitting diodes). The plurality of combustion simulating elements 210 may each have an arm 211 with a first end 213 and a second end 212, the first ends 213 each comprising a light-emitting device 220. FIG. 2A and FIG. 2C show the plurality of combustion simulating elements 210 in a first position, and FIG. 2B and 2D show the plurality of combustion simulating elements 210 in a second position, after actuation via a controller and actuator (see FIG. 1A), wherein the light-emitting devices are more spatially dispersed than in the first position. The arms 211 may each comprise a flexible material operable to fall out of the sleeve 230 with gravity, e.g., to give the impression of falling sparks.

[0059] The special effects device 200 may be used in combination with a combustion effect system, the combustion effect system comprising a projection or display screen (e.g., a VFX projection screen, a curved or flat panel display) for showing a visual effect. Alternatively, the special effects device 200 may be combined with a practical effect device, such as an air canon that projects colored smoke and/or other practical effect. The special effects device 200 may also be used in combination with an audio emitter (e.g., a speaker) for sounding an audio effect. In other embodiments, the special effects device 200 may be used in combination with other light effects (e.g., simulating an explosion, fire, or other combustion effect).

[0060] The light-emitting devices 220 may comprise a light-emitting diode and may be operable to emit light of a first color and first intensity and then switch to emitting light of a second color and/or second intensity. A controller may be in electronic communication with the light-emitting devices 220 and operable to change the emitted light color and/or intensity of light-emitting device 220 as a function of a predetermined parameter, such as time after actuation (e.g., causing the actuator to extend the light-emitting devices 220 from the sleeve 230), or depending on the distance traveled from the first position to the second position.

[0061] The sleeve 230 may comprise a rigid, substantially cylindrical shape defining a channel 231. The sleeve 230 may comprise any rigid material of sufficient strength to support the combustion simulating elements as they move in and out of the sleeve 230 and resist damage from operation of the special effects device 200. The sleeve 230 may have a first end 232 and a second end 233. The second end 233 may be distal in relation to the actuator and may comprise an opening through which the distal ends 212 of the combustion simulating elements 210 emerge upon actuation, and the end 232 may be proximal to the actuator. The channel 231 may comprise an inner diameter chosen to allow the plurality of combustion simulating elements 210 to pass through the channel rapidly and without becoming tangled.

[0062] The static light-emitting devices 225 may comprise a plurality of light-emitting diodes arranged in a row around a portion of the circumference of the second end 233 of the sleeve 230, such that light emitted from the static light-emitting devices 225 may simulate a combustion source or ignition point (e.g., an ember, or an electric arc) for the sparks simulated by the combustion simulating elements 220. The static light-emitting devices 225 may be operable to emit light of a first color and first intensity and switch to emitting light of a second color and/or second intensity as a function of time prior to actuation.

[0063] The actuator may comprise any mechanism operable to cause the combustion simulation elements to quickly move from a first position to a second position (e.g., compare FIGS. 2A and 2B). The actuator may comprise an extension member which is mechanically extended by the action (e.g., electric actuation) of the actuator. The actuator may be in electronic communication with the controller, which provides an electronic communication or electrical signal to activate the actuator at a pre-determined time. The actuator may have a predetermined stroke length (e.g., the length to which the extension member is extended), such that the distal ends 212 of the combustion simulating elements 210 are extended out of the sleeve 230 to predetermined lengths.

[0064] The controller may comprise any system operable to initiate the actuator and control the light-emitting devices 220 (e.g., light up upon actuation, change color and/or intensity as a function of time or position, and shut off prior to being retracted back to the first position) and static light-emitting devices 225 (e.g., light up prior to actuation, change color and/or intensity as a function of time, and shut off upon actuation). In some embodiments, the controller may be operable to connect with a central control system, e.g., a general purpose computer having software operable to run controllers of multiple effects devices. The central control system may be in electronic communication with the controller for light-emitting devices 220 and the actuator. The central control system may provide activation signals to the controller for the light-emitting devices 220 and the actuator via wired or wireless signal. The central control system may be additionally in electronic communication with one or more additional special or theatrical effect devices. In some embodiments, central control system may transmit data in an industry standard format, e.g. Digital MultipleX (DMX) format, to the controller for light-emitting devices 220 and the actuator and the controllers for other effect devices. The central control system may be operable and have programming that coordinates different combustion effect devices to create a coordinated realistic overall effect that simulates, e.g., an explosion, canon fire, etc.
