Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model adopts the polymeric material lithium battery, does not need maintenance, reliable and stable, safety and environmental protection, efficiently gently little, makes the integrated setting of mine lamp become possibility.
2, the utility model adopts the low-voltage high-efficiency luminous tube, has 1,000,000 hours useful life, can not produce naked light.
3, the incorporate structure of the utility model is provided with the thorough constraint that external stube cable brings of having eliminated, and uses free and relaxed.
4, the utility model has greatly alleviated miner's carry-on heavy burden, improves its condition of work.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model control board circuit theory diagrams.
Number in the figure: 1 battery, 2 luminous tubes, 3 circuit boards, 4 battery cases, 5 lamp holders, 6 are moulded shell backboard, 7 and are buckled interface, 8 charging jacks, 9 fin.
Embodiment:
Referring to Fig. 1, present embodiment adopts the lithium ion battery 1 of polymeric material, and with low-voltage high-efficiency LED luminous tube 2 as light source, with lithium ion battery 1, luminous tube 2 and circuit board 3 integrated setting, this integrated setting is that the integrated shell of moulding is set, the battery case 4 that is used for fixing battery and circuit board is positioned at the top of moulding shell, and lamp holder 5 is positioned at the bottom of moulding shell, and the shell backboard 6 of moulding that is positioned at the lamp holder back is provided with and buckles interface 7 and charging jack 8.
Low-voltage high-efficiency LED luminous tube is a kind of new type light source, and its model is LW W5SG, and the power of exportable nearly 1W under the low-voltage of 3.7V has greatly improved the illuminating effect of underground work.In order to guarantee its functional reliability, fin 9 should be set at the back of luminous tube 2, use the copper clad laminate of 0.74mm to make.
Referring to Fig. 2; the charge-discharge protection circuit that is made of protection chip U1 and field effect transistor Q1, Q2 is set on circuit board; wherein; the base stage of field effect transistor Q1 connects control end 1 pin of chip U1; the base stage of field effect transistor Q2 connects control end 3 pin of chip U1; the both positive and negative polarity of DC power supply is carried in EB+ and EB-end, and the working range of supply voltage is 0-24V.Charge circuit is made up of field effect transistor Q1, lithium ion battery protection chip U1 and battery pack BT1, BT2, BT3; when cell voltage reaches 3.9-4.3V; the overvoltage charged state is detected; the pin one of chip U1 is set to high potential automatically; this high potential causes field effect transistor Q1 to turn-off, and circuit is realized overvoltage protection.When the over proof current value of charging current, the pin 3 of chip U1 is configured to power source charges voltage, cause thus chip U1 pin one high potential and field effect transistor Q1 is turn-offed, implement overcurrent protection.Discharge loop is made up of field effect transistor Q2 and lithium ion battery protection chip U1 and battery pack BT1, BT2, BT3; when cell voltage is lower than 2.0V; the overvoltage discharge condition is detected; at this moment; the pin 3 of chip U1 is set to high potential; thereby field effect transistor Q2 is turn-offed, realize the overvoltage discharge prevention.
