The battery is designed as two independent identical blocks located on the outer side of the helmet symmetrically about the plane of symmetry of the helmet in position, balancing the headlight relative to the center of gravity of the helmet. Each block is made of several small batteries, fuses and control circuit of the charge located in the hermetically sealed casing, provided with a device for mounting on the helmet with the possibility of removal.

The positive electrodes of each unit is connected through a fuse with resistors and through the control circuit of the charge with positive internal contact lights. As a small battery in rechargeable battery is etenia is a significant reduction in the mass of the elements power of the lamp, placing them on the helmet miner and improving the reliability of the lamp. 1 C.p. f-crystals, 4 Il.The invention relates to lighting mining equipment for individual use.Known mine lamp for individual use, consisting of lights, which includes a matrix of LEDs emitting white light, and a transparent window with lenses, accessories for mounting lights on the helmet miner, connecting cord, housing with rechargeable batteries and a means of sealing the patent 2187039, M. CL. 6 F 21 L 4/00, publ. 10.08.2002 and miner helmet according to GOST 12.4.091-80.The disadvantages of the known lamp, selected as a prototype for the patent 2187039, M. CL. 6 F 21 L 4/00, publ. 10.08.2002 are a great weight and dimensions of the battery, worn on the belt of the miner, the existence of a long cord that connects the battery and the headlight, which can be a source of interference to the movement of the miner. In addition, the supply voltage of the lamp provided by the battery, requires selection of LEDs with the lowest forward voltage drop across the led when the rated current flowing through the led.The technical result of the invention I have about reliability.The technical result is achieved by the fact that in mine lamp for individual use, containing Faro, which has a matrix of LEDs, connected in series with resistors one for each led fixture for mounting lights on the helmet miner, housing with rechargeable batteries and connecting cord, according to the invention, the battery is designed as two independent identical blocks located on the outer side of the helmet symmetrically about the plane of symmetry of the helmet in position, balancing the headlight relative to the center of gravity of the helmet, each block is made of several small batteries, fuses and control circuit of the charge located in a sealed housing, equipped with a device for mounting on the helmet with the possibility of removal, while the negative electrodes of each unit is connected to the negative external contact lights and the first contact switch, the second switch contact is connected to the cathodes of all LEDs, the positive electrodes of each unit is connected through a fuse with resistors and through the control circuit of the charge with positive internal contact lights.In idnia batteries.Mine lamp illustrated by drawings, where Fig.1 shows a view of the lamp of Fig.2 is a cross-section of the helmet at the level of the plane containing the centers of gravity lights, helmets and battery packs; Fig.3 is a longitudinal section of the battery pack of Fig.4 is a circuit diagram of the lamp.In the drawings identified the following elements of the lamp: 1 - helmet; 2 lamp; 3 - battery pack; 4 - battery; 5 - housing unit batteries; 6 - the center of gravity of the headlamp; 7 - window lights; 8 - device for mounting lights on the helmet miner; 9 - the center of gravity of the helmet; 10 - the center of gravity of the accumulator unit; 11 - fuse; 12 - diagram of the charge control; 13 - paradisiacal; 14 - a device for attaching battery packs on the helmet; 15 - holder battery pack; 16 - connecting cord; 17 - switch; 18 - negative external contact; 19 - positive inner contact.The essence of the proposed solution consists in the following. A stable position of the helmet 1 with a lamp on the head of the miner is provided, if the battery pack will balance the Faro 2 relative to the center of gravity of the helmet. While the centers of gravity of the headlamp, battery and helmets must be on the same line, legadembi lights, it is necessary to ensure that the center of gravity of the battery was closer to the center of gravity of the helmet than the center of gravity of the headlamp. This is possible if the battery pack is made of two identical units 3 battery 4, is placed in a sealed casing 5. When this blocks 3 are placed on the outside of the helmet symmetrically about the plane of symmetry of the helmet. In this case, the distance from the center of gravity of the helmet to the straight line connecting the centers of gravity of the battery module, is given by the formulawhere mf- mass lights, mbthe weight of each battery block, lfdistance from the center of gravity of the headlamp to the centre of gravity of the helmet. In addition, when using two battery packs provide a more uniform load distribution on the helmet, as well as decrease the dimensions of the protruding elements of the lamp.From a practical point of view we can assume that the center of gravity 6 of the headlight 2 is located at the middle point of the axis of Windows 7 lights 2, the ends of which lie on the outer surface of the window 7 and the outer side of the device 8 for mounting lights 2 on the helmet 1 and the center of gravity 9 of the helmet 1 is located in the middle of the line segment that defines the external size of the helmet 1 and leases is. ulozhenie center of gravity 10 of each block 3 battery 4 is determined on the basis of its design.The positive effect of the use of rechargeable batteries in the form of two identical units 3 battery 4 can be strengthened by use of an independent connection blocks 3 in the electrical circuit of the lamp. This requires each unit of 3 of the 4 batteries to supply the fuse 11 and the control circuit of the charge 12. The control circuit of the battery 12 provides for disabling the charging circuit when the preset voltage of the battery 4, and in the case of applying the Nickel-metal hydride batteries and in excess of a predetermined threshold temperature of the batteries. Fuse 11 protects the battery 4 from damage during the occurrence of a short circuit in the external to unit 3 of 4 batteries of an electric circuit. This connection led through resistors must provide the same power from each unit 3 of 4 batteries. In this case, the nominal electric capacity of each battery 4 is determined by the formulawhere IH- rated current consumed by all the LEDs; t is the required uptime Svetlana lights 2 on the helmet 1 is then pushed into paradisiacal 13. Blocks 3 battery 4 by means of the fixture 14 for fastening the blocks 3 of the 4 batteries on the helmet 1 is also inserted all the way into the holders 15 units 3 battery 4. Spotlight power supply 2 via connecting wires 16 from blocks 3 battery 4 via the switch 17. Charging units 3 battery 4 is made through a negative external contact 18 lights 2 and positive inner contact 19 lights 2.For example, for a lamp described in the prototype, for 19 LEDs with a forward voltage drop of 3.6 V (typical) at rated current through the led is 20 mA and t=10 h, we get QH=1,9 Andincluding Such electric capacity and the required voltage is within the optimum rates and provide mass for 4 AA NiMH battery type AA in each battery pack. The total mass of lights, battery packs, wires and helmets does not exceed 0,9 kgThe positive effect is that the greatly reduced mass of the elements power of the lamp, so you can put on the helmet miner, providing stable fixation of the helmet on the head of the miner, as well as increased reliability is litvania, containing Faro, which has a matrix of LEDs, connected in series with resistors one for each led fixture for mounting lights on the helmet miner, housing with rechargeable batteries and connecting cord, characterized in that the battery pack is designed as two independent identical blocks located on the outer side of the helmet symmetrically about the plane of symmetry of the helmet in position, balancing the headlight relative to the center of gravity of the helmet, each block is made of several small batteries, fuse, control circuit charge located in the hermetically sealed casing, provided with a device for mounting on the helmet with the possibility of removal, meanwhile, the negative electrodes of each unit is connected to the negative external contact lights and the first contact switch, the second switch contact is connected to the cathodes of all LEDs, the positive electrodes of each unit is connected through a fuse with resistors and through the control circuit of the charge with positive internal contact lights.2.
