text: the percussion - triggered lighting system provides a number of internal and external lights for drums , which are constantly lighted or are lighted upon percussion of the drum ( s ). various other lighting systems and controls may be provided for the momentary illumination of the lights without percussion of the drum ( s ), and / or other lighting remote from the drum ( s ), drummer , and controls . the system may also be used to control a video projector disposed within one or more of the drums . the system may be retrofit to an existing drum kit as an after - market improvement . fig1 of the drawings provides a schematic illustration of the basic percussion triggered lighting system of the present invention . in fig1 , two bass drums 10 are provided . each of the drums has a translucent drum head 12 ( shown in fig2 b ) in order to allow light to pass from the interior of the drums through the drum head for viewing external to the drum . each of the drums has a steady light 14 disposed therein , i . e ., a light that is illuminated continuously throughout the performance , rather than being controlled by percussion of the drums . each of the drums 10 further has a percussion activated or controlled light 16 therein . the internal drum lights 14 and 16 may be any desired type of lighting , e . g ., incandescent , fluorescent , etc ., but are preferably light emitting diodes ( leds ) due to their durability and rapid response time for use as a percussively activated light . while the schematic drawing of fig1 illustrates both steady and percussively illuminated lights 14 and 16 within each of the drums 10 , it will be seen that either or both types of lighting may be installed in either or both bass drums 10 , as desired . each of the bass drums 10 may also include one or more strings of percussion - triggered external lights 18 disposed circumferentially about their rims 20 . the peripheral external lights 18 may be actuated to illuminate in any of various predetermined sequences , e . g ., in consecutive sequence around the string or strings to produce the appearance of rotation , alternating illumination , etc ., as desired . the percussion - triggered lighting system may further include at least one , and preferably a small number of intermediate drums 20 , known as “ tom - toms .” the drum heads of the tom - toms 20 are also made of a translucent material in the manner of the translucent drum heads of the bass drums 10 . the tom - toms 20 may also include steady illumination sources 22 therein , as well as percussively actuated lights 24 , similarly to the respective lights 14 and 16 of the bass drums 10 . a snare drum 26 may also be included in the drum kit . the snare drum also contains a steady light 28 and a percussively controlled light 30 therein . as the beat of a snare drum is of relatively short duration , a timer delay switch 32 may be provided to delay the opening of the actuation switch for the percussively actuated light 30 for a short time , e . g ., one half second or so , after a drum beat . the timer delay switch 32 may be adjusted to provide any practicable duration for the light 30 . electrical power is provided for the above - described lighting system by a conventional electrical source 34 , e . g ., the a . c . power mains , a generator for remote locations , etc . electrical power is received from the electrical power source 34 by a switch panel 36 that serves to distribute the electrical power to the various lights described further above . the switch panel 36 includes a first switch 38 a that provides power to the steady lights 14 , 22 , and 28 of the corresponding drums 10 , 20 , and 26 , a second switch 38 b that provides power to the percussively actuated lights 16 , 24 , and 30 of those respective drums , and a third switch 38 c that provides power to the peripheral lights 18 of the one or more bass drums 10 . the switch panel 36 may comprise a dimmer control panel in which each of the switches 38 a through 38 c comprises a dimmer switch , if desired . there may be times during the course of a performance that the actuation of the percussively controlled lights within the various drums may be desired , but no drum beat is desired at that particular point in the performance . the percussion - triggered lighting system provides for the actuation of the various drum lights without requiring a drum beat by a light switch array 40 located remotely from the various drums 10 , 20 , and 26 . the term “ remotely ”, in terms of the location of the light switch array 40 , means that the array 40 is not necessarily attached to any of the drums , but is within convenient reach of the drummer during the performance . the light switch array 40 includes a number of percussion actuated switches 42 a through 42 e , each of the switches 42 a - 42 e controls some function of the various lights of the system . each of the switches 42 a through 42 e comprises a relatively soft pad with a contact switch or touch switch therein , so that a strike of the pad of the switch produces nearly no sound due to the acoustic properties of the pad . the sound of a strike upon any of the switches 42 a through 42 e cannot be heard by the audience due to the overall sound of the musical performance while playing . a first switch 42 a may serve as a master power switch for the system , receiving electrical power from the power source 34 . a second switch 42 b may serve to provide electrical power to some external lighting array 44 located remotely from the drums , e . g ., stage lighting , etc . a third switch 42 c may control electrical power to the switch 38 a of the switch panel 36 , thereby controlling the power to the steady lights steady lights 14 , 22 , and 28 of the corresponding drums 10 , 20 , and 26 . a fourth switch 42 d may control electrical power to the second switch 38 b of the switch panel 36 , thereby controlling power to the percussively actuated lights 16 , 24 , and 30 of those respective drums . a fifth switch 42 e may control electrical power to the third switch 38 c of the switch panel 36 , thereby controlling power to the peripheral lights 18 of the one or more bass drums 10 . the above - described light switch array 40 and the various switches 42 a through 42 e are exemplary , and the number , arrangement , and functions of the various switches may be adjusted as desired . at least some of the various lights of the various drums are controlled by percussive strikes of the various drums , as described further above . the switches for illuminating the associated lights due to drum strikes or beats are located within the respective drums . fig2 a and 2b of the drawings provide internal views of an exemplary bass drum 10 . it will be understood that percussively actuated lights disposed within the tom - tom drums 20 and / or snare drum 26 use essentially the same switch configuration . the switch mechanism illustrated in fig2 a and 213 includes an electromechanical microswitch 46 ( shown in fig2 b ) installed within the drum 10 on a mounting bracket 48 , and an actuator arm 50 extending from a pivot point at the base of the bracket and / or microswitch 46 to a resilient contact bumper 52 at the distal end of the arm 50 . fig2 a and 2b also show a ballast weight 54 installed within the drum 10 to stabilize the drum kit and its attached tom - toms and other attached equipment ( e . g ., cymbals , etc .). the electromechanical switch assembly operates when the drum 10 is struck , so that the drum head 12 flexes and reverberates inward and outward , accordingly . the moving drum head 12 transfers motion to the contact bumper 52 of the actuator arm 50 , thus causing the actuator arm 50 to move and transfer its motion to the microswitch 46 by means of its switch contact . the opening and closing of the microswitch 46 causes the percussion - triggered light 16 within the drum 10 to illuminate momentarily . the same switch assembly may also communicate electrically with the external lights 18 installed peripherally about the rim 20 of the drum 10 ( and / or other drums , if so desired ). fig3 a and 3b illustrate another embodiment of the percussion - triggered lighting system in which a video projector is installed within a drum 56 . the drum 56 may be a bass drum similar to the bass drums 10 of fig1 through 2b , or other desired drum type . rather than having various percussion - actuated and steady lighting within the drum 56 , a video projector 58 is installed therein on a bracket 60 . the projector 58 has a lens 62 adjusted to project an in - focus image on the inside of the translucent drum head , and receives electrical power and video signal from a projector control system 64 ( shown in fig1 ) disposed external to the drum 56 . the projector 58 may also be electrically connected to a percussively actuated microswitch , such as the microswitch 46 and contact arm 50 illustrated in the drum 10 of fig2 , to actuate or deactivate the video display , and / or to switch the display to different displays , if desired . one or more conventional video cameras ( not shown ) may be set up to receive video images of one or more of the performers , scenes of the audience , and / or other scenes , so that the drummer or other personnel ( e . g ., a lighting technician ) may switch the scene ( s ) as desired during the course of the performance . alternatively , the video projection system may be installed within one or more of the bass drums 10 in addition to the steady and percussively actuated lights 14 and 16 , as indicated in broken lines in fig1 . it is to be understood that the present invention is not limited to the embodiments described above , but encompasses any and all embodiments within the scope of the following claims .
