Definitions

  • the present invention relates to a hands-free lighting system, and more particularly to a lighting system intended to be controlled by the mouth.
  • Mouth-operated lighting systems are used in the aeronautical field, where they are fixed on the helmets of pilots or flight personnel. During night flights, they allow for example the lighting of the cockpit, the reading of charts, the visualization of poorly lit instruments, or even interventions in dark areas like the holds of the aircraft.
  • a momentarily controlled switch comprises a contact-carrying blade mounted under stress in a first convex position, the blade being able to tilt in a second position under the effect of a thrust applied by means of a ordered.
  • the effort exerted by the user with his lip on the control member simply serves to tilt the blade, the electrical contact between the internal contact pads of the switch being ensured by the elasticity of the blade .
  • the tilting of the blade produces a characteristic click accompanied by a tactile effect due to the relaxation of the elastic stress.
  • momentary switch models fitted with levers that further reduce the control effort, which can then drop below 10 grams.
  • momentary switches have the disadvantage of not allowing the lighting to be locked, the contact-carrying blade returning to its initial position when the control member is released. The user is thus forced to keep his lip pressed on the switch during periods of use.
  • the general objective of the present invention is to provide a lighting system controlled by the mouth which can be locked while being ergonomic.
  • a lighting system intended to be controlled by the mouth, comprising lighting means and switch means for locking or unlocking the lighting, in which the switch means comprise a low force switch with momentary control. electrically coupled with a bistable electronic switch, the lighting being locked by the bistable electronic switch, the bistable electronic switch being controlled by the momentary switch.
  • the bistable electronic switch can be produced simply, for example by means of a rocker D.
  • the bistable electronic switch controls the lighting means by means of at least one transistor.
  • the momentary control switch and the lighting means are arranged in a first lighting box, and the bistable electronic switch arranged in a second box.
  • the lighting box is mounted at the end of a flexible rod.
  • the other end of the flexible rod may include fixing means arranged so that they can be slidably mounted on a microphone arm.
  • the system comprises visible lighting means, infrared lighting means and a general switch with three positions making it possible to choose between a visible lighting position, a position d infrared lighting, and a lighting off position.
  • FIG. 1 represents an aircraft piloting helmet 1 equipped with a microphone 2 and a lighting system 3 according to the present invention.
  • FIG. 2 shows in more detail the microphone 2 and the lighting system 3.
  • the lighting system 3 according to the invention comprises a lighting box 30 conventionally equipped with two green LED diodes 31 and an infrared LED diode 32 provided for flights with night vision goggles.
  • the lighting box 30 is mounted at the end of a flexible rod 33, the other end of which is fixed to the distal part 21 of an arm 22 carrying the microphone 2.
  • the distal part 21 of the microphone arm comprises two parallel bars 21-1, 21-2 on which a fixing piece 34 of the flexible rod 33 is slidably mounted, the position of the fixing piece 34 being able to be locked by a clamping screw.
  • the lighting box 30 has an elongated shape which is substantially curved so as to match the rounded shape of the microphone 2.
  • the lighting unit 30 comprises a switch 35 of the momentary low-force type, the control member 36 of which is a lever 36-1 acting on a pusher 36-2.
  • the lever 36-1 takes the form of a metal or plastic tab oriented towards the pilot's mouth. Thanks to the flexible rod 33, the sliding fixing piece 34 and the particular shape of the lighting box 30, the lighting box 30 can be placed as close as possible to the microphone 2 so that the lever 36-1 is easily accessible.
  • the switch 35 is for example a microswitch of the "Subminiature micro switch series SM" series sold by ZIPPY, which can be switched with an effort of around 30 grams.
  • the switch 35 is combined with a bistable electronic switch, an exemplary embodiment of which will be described later in relation to FIG. 4.
  • the function of the bistable switch is to memorize, that is to say say lock, the state of the lighting system after the switch 35 has been actuated.
  • the user benefits from the advantages of the momentary control switch, already exposed to the preamble (low effort, distance between the lever 36- 1 and the user's constant mouth, click effect, tactile effect), while benefiting, virtually, from the advantages of locking switches.
  • the electronic function is carried over into a second housing 37 fixed to the proximal part 24 of the arm 21 of the microphone, the housing 37 being connected by an electrical cable 38 to the lighting housing 30.
  • This second housing 37 is further equipped with '' a general switch 39 with three positions allowing to choose between a visible lighting position (green diodes), an infrared lighting position (red diode) and a deactivation position in which an action on the lever 36 -1 does not trigger the lighting.
  • FIG. 4 represents the electrical diagram of the lighting system 3 according to the invention.
  • the bistable electronic circuit is here produced by means of a flip-flop D referenced 40, whose inverted output / Q is brought back to the control input D.
  • the clock input CLK of flip-flop D is attacked by the output of the momentary control switch 35, whose input receives a supply voltage Vcc from the system.
  • Vcc supply voltage
  • the CLK input receives a voltage pulse which causes the state of the D flip-flop to change, the Q output passing alternately to the value 1 (Vcc ) or 0 (mass) depending on the previous state of the scale.
  • the CLK input is connected to ground by a “pull-down” resistor (or “pull down” resistor) R1 of high value in parallel with a capacitor C1, and to the voltage Vcc by a “pull-up” resistor (or “pull-up” resistor) R2 also of high value.
  • Resistors R1 and R2 are for example 10 K ⁇ and 100K ⁇ , respectively
  • the output Q of the flip-flop D is applied to an input terminal 39-1 of the general switch 39 with three positions.
  • the switch 39 has three output terminals 39-2, 39-3, 39-4 corresponding respectively to the three possibilities mentioned above: lighting in the visible (green), lighting out of service, lighting in the infrared.
  • Terminal 39-2 drives the base of a transistor 41 for controlling the green diodes 31, via a low-value resistor R3 of high value and a buffer resistor R4.
  • Terminal 39-3 is not connected.
  • Terminal 39-4 drives the base of a transistor 42 for controlling the infrared diode 32, by means of a low-value resistor R5 of high value and a buffer resistor R6.
  • the green LED diodes 31 and the infrared diode 32 receive on their cathodes the supply voltage Vcc and their anodes are connected via buffer resistors R7, R8, R9 to the collectors of the transistors 41, respectively 42, whose transmitters are connected to ground.
  • the output Q of the flip-flop D changes to 1 and turns the transistor 41 on, the green diodes 31 being thus supplied.
  • the user must press the switch 35 again so that the output Q goes to 0.
  • these various electronic elements are arranged in the housing 37 of FIG. 2, with the exception of the switch 35 and the diodes 31, 32 which are integral with the lighting housing 30. Furthermore , the housing 37 may contain accumulators which supply the voltage Vcc.
  • the present invention is not limited to the production of a lighting system for an aircraft piloting helmet. Because of the ergonomic advantages which the system according to the invention provides, other applications can be envisaged, in particular the production of lighting systems for the disabled, the production of hands-free infrared remote control systems usable by the disabled, in the field of surgery for the start-up of certain devices (respiratory, laser generators, ...) during an operation, in the industrial field, etc. Also, the present invention can be applied to the production of aiming systems, the diodes described above being replaced by one or more laser diodes. Thus, in the present patent application, the word "lighting" should be understood as generally designating the emission of a light beam, whether this light beam is intended to illuminate objects, control an apparatus, or designate a lens. .
