Definitions

  • the present invention relates to a system hands-free lighting, and more particularly a lighting system intended to be controlled by the mouth.
  • Mouth control lighting systems are used in aeronautics, where they are fixed on helmets of pilots or staff sailing. During night flights, they allow by example cockpit lighting, reading maps, viewing poorly lit instruments, or still interventions in dark areas like aircraft holds.
  • US-A-5083246 describes an aircraft piloting helmet comprising a lighting system intended to be controlled by the tongue or the lips of the user, comprising lighting means and switch means for locking or unlocking the lighting.
  • control switches momentary have the disadvantage of not allowing light lock, contact blade returning to its original position when the organ of command is released. The user is thus forced keep his lip pressed on the switch for periods of use.
  • the general objective of the present invention is to provide a lighting system controlled by the mouth that can be locked while being ergonomic.
  • a system lighting to be controlled by mouth comprising lighting means and means switches to lock or unlock lighting, in which the switch means include a low effort control switch momentary electrically coupled with a switch bistable electronics, the lighting being locked by the bistable electronic switch, the switch bistable electronics being controlled by the switch momentary order.
  • the bistable electronic switch can be carried out simply, for example by means of a rocker D.
  • the switch bistable electronics controls the lighting means by through at least one transistor.
  • the switch to momentary control and the lighting means are arranged in a first lighting box, and the bistable electronic switch arranged in a second box.
  • the housing lighting is mounted at the end of a flexible rod.
  • the other end of the flexible rod may have fixing means designed to be able to be mounted sliding on a microphone arm.
  • the system comprises means of lighting in the visible, means infrared lighting and a general switch with three positions allowing to choose between a visible lighting position, one position infrared lighting, and a focus position lighting out of service.
  • Figure 1 shows a pilot's helmet aircraft 1 equipped with a microphone 2 and a system lighting 3 according to the present invention.
  • Figure 2 shows in more detail the microphone 2 and the system lighting 3.
  • the lighting system 3 according to the invention includes a lighting box 30 so equipped classic two green LEDs 31 and one LED infrared 32 intended for flights with sunglasses night vision.
  • the lighting box 30 is mounted at the end of a flexible rod 33, the other end of which is fixed on the distal part 21 of an arm 22 carrying the microphone 2.
  • the distal part 21 of the arm of the microphone includes two parallel bars 21-1, 21-2 on which is slidably mounted a fixing piece 34 of the flexible rod 33, the position of the workpiece fixing 34 can be blocked by a clamping screw.
  • the housing lighting 30 has a substantially elongated shape curved so as to follow the rounded shape of the microphone 2.
  • the housing lighting 30 includes a switch 35 of the weak type momentary control effort including the control member 36 is a lever 36-1 acting on a pusher 36-2.
  • the lever 36-1 takes the form of a metal or plastic tongue facing the mouth of the pilot. Thanks to the flexible rod 33, to the piece of sliding fixing 34 and to the particular shape of the light box 30, light box 30 can be placed as close as possible to microphone 2 so that the lever 36-1 is easily accessible.
  • the switch 35 is for example a microswitch of the series "Subminiature micro switch series SM" marketed by ZIPPY, which can be switched with an effort of around 30 grams.
  • the switch 35 is combined with a bistable electronic switch, one of which example of embodiment will be described later in relation with figure 4.
  • the function of the bistable switch is to memorize, i.e. lock, the state of the lighting system after switch 35 has been operated. So when the user pushes the lever 36-1 with its lip (or its tongue), the lighting is engaged and the lever can be released. To turn off the light box 30, the user must operate at again lever 36-1.
  • the user benefits from advantages of the momentary switch, already exposed to the preamble (low effort, distance between lever 36-1 and the user's mouth constant, click effect, tactile effect), while benefiting, advantages of switches locking.
  • the electronic function is reported in a second housing 37 fixed on the proximal part 24 of the arm 21 of the microphone, the housing 37 being connected by a electric cable 38 to the light box 30.
  • This second box 37 is further equipped with a switch general 39 with three positions allowing to choose between a visible lighting position (green LEDs), an infrared lighting position (red LED) and a deactivation position in which an action on the lever 36-1 does not trigger the lighting.
  • FIG. 4 shows the electrical diagram of the lighting system 3 according to the invention.
  • the circuit bistable electronics is here realized 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 exit of the momentary switch 35, the input of which receives a supply voltage Vcc from the system. So, when the user presses with his lip lever 36-1, the CLK input receives a pulse tension which makes change the state of rocker D, the output Q alternately passing to the value 1 (Vcc) or 0 (mass) according to the previous state of the scale.
  • the CLK input is connected to ground by a "low-draw” resistor (or “pull down” resistance) R1 of high value in parallel with a capacitor C1, and at the voltage Vcc by a “pull-up” resistance (or “pull-resistance” up ”) R2 also of high value.
  • the resistors R1 and R2 are for example 10 K ⁇ and 100K ⁇ , respectively
  • the Q output of flip-flop D is applied to a input terminal 39-1 of main switch 39 to three positions.
  • the switch 39 has three terminals of output 39-2, 39-3, 39-4 corresponding respectively to three possibilities mentioned above: lighting in the visible (green), lighting out of service, lighting in infrared.
  • Terminal 39-2 attacks the base of a transistor 41 for controlling the green diodes 31, by via a strong R3 low-pull resistor value and a buffer resistance R4.
  • Terminal 39-3 is not not connected.
  • Terminal 39-4 attacks the base of a transistor 42 for controlling the infrared diode 32, by via a strong R5 low-pull resistor value and a buffer resistance R6.
  • LED diodes lights 31 and 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 the mass. So, for example, when the general switch 39 is in the visible lighting position and that the user momentarily operates lever 36-1 of the low-effort switch 35, the output Q of the flip-flop D goes to 1 and turns transistor 41 on, the green diodes 31 thus being supplied. To turn off the diodes 31, the user must actuate again switch 35 so that output Q goes to 0.
  • these various elements electronics are arranged in the housing 37 of the Figure 2, with the exception of switch 35 and diodes 31, 32 which are integral with the lighting housing 30.
  • the housing 37 may contain accumulators which supply the voltage Vcc.
  • the present invention is not limited to the realization of a lighting system for aircraft piloting helmet. Because of the benefits ergonomic that the system according to the invention provides, other applications can be envisaged, in particular the realization of lighting systems for people disabled, the realization of remote control systems infrared hands free usable by people disabled, in the field of surgery for the setting en route of certain devices (respiratory, laser generators, ...) during an operation, in the industrial, etc. Also, the present invention can be applied to the realization of aimed, the diodes described above being replaced by one or more laser diodes. So in the present patent application, the word "lighting" must be understood to mean generally the issuance of a light beam, that this light beam is intended lighting objects, ordering equipment, or designate a goal.
