Description
Technical field
The utility model relates to a kind of mine lamp, refers to a kind of LED mine lamp that utilizes lithium battery power supply especially.
Background technology
Present domestic mine lamp adopts the mining bulb of 0.6～0.7A, parabolic mirror, convex lens combining structure mostly.As No. 98222347.1 patent of Patent Office of the People's Republic of China in bulletin on September 10th, 1998, its name is called " mine lamp ", promptly disclosed a kind of like this mine lamp, but matching used power supply (such as lead-acid accumulator or nickel-hydrogen accumulator etc.) volume is big as the one, weight is also bigger, about 2～2.5 kilograms, carry inconvenience; Bulb power consumption is big, and temperature can can't reach essential safety up to several Baidu when bulb used; And service life is short, needs often to change; When most importantly using under coal mine, if glass lens and bulb fragmentation, because the too high meeting of filament temperature causes gas explosion, or power supply short circuit sparking meeting causes gas explosion, causes casualties and property loss.In addition, lead-acid accumulator is big except volume, also use strong acid the heaviness, is threatening the user constantly.
Summary of the invention
Big, heavy and use unsafe deficiency for overcoming existing mine lamp power consumption, the utility model proposes a kind of mine lamp that adopts the LED of lithium battery.
The technical scheme that the utility model adopted is: a kind of LED mine lamp is provided; it includes charging socket, holding circuit, LED light emitting source that is electrically connected with holding circuit that is used to connect outer charge power supply and the shell mechanism that holds these devices; further comprise a lithium battery, this lithium battery is electrically connected with described holding circuit.
Described LED light emitting source further includes a main LED light emitting source and a standby LED light emitting source, and main LED light emitting source and standby LED light emitting source all include at least one LED lamp.
Described main LED light emitting source and standby LED light emitting source are selected one by a gauge tap and are electrically connected with described holding circuit.
The quantity of LED lamp is greater than the quantity of LED lamp in the standby LED light emitting source in the described main LED light emitting source.
Also be serially connected with a current-limiting resistance between described holding circuit and the light emitting source.
The beneficial effects of the utility model are: the utility model has adopted lithium battery to power, and adopts the little LED of power consumption to throw light on, thus the utlity model has in light weight, can repeatedly use, advantage that lighting hours is grown.In addition, because LED is a cold light source, thus can not cause gas explosion owing to temperature is too high, and this mine lamp employing Seal Design, add that the design of holding circuit can make the utility model more safe and reliable.
Description of drawings
Fig. 1 is the block diagram of the utility model lithium battery LED miner's light.
Fig. 2 is the circuit theory diagrams of the utility model lithium battery LED miner's light.
The specific embodiment
As shown in Figure 1, be the block diagram of the utility model lithium battery LED miner's light.Therefrom as can be known, the utility model includes charging socket, holding circuit, lithium battery and LED light emitting source and holds the shell mechanism of these devices.Entire circuit can be made of one encapsulation, and whole casing has only the input hole of charging socket and the handle of dialling of gauge tap to be exposed to the outside, and other partly all can make Seal Design.
Present embodiment utilizes light emitting diode (LED) to throw light on, and wherein, the LED light emitting source includes main LED light emitting source and standby LED light emitting source.This main LED light emitting source and standby LED light emitting source all include at least one LED lamp, and the quantity of main LED light emitting source is generally greater than standby LED light emitting source.Be plugged on this charging socket with the supporting special charger of this mine lamp by one; can charge to described lithium battery; and holding circuit also includes testing circuits such as voltage/current, and whether the voltage/current that is used to detect charging and discharging lithium battery overvoltage (stream) or under-voltage (stream).
As shown in Figure 2, be circuit theory diagrams of the present utility model.Holding circuit can be by charging socket and external power (as civil power etc.; do not draw) connect; its other end is connected with lithium battery; and the rear end of this holding circuit is connected in parallel to main LED light emitting source (D2, D3......D13) and standby LED light emitting source (D1); wherein; the quantity of main LED light emitting source and standby LED light emitting source is decided according to concrete condition; adopt 12 and 1 in the present embodiment respectively; also can adopt other quantity, but the quantity of main LED light emitting source is generally greater than the quantity from the LED light emitting source.And utilize a gauge tap K that main LED light emitting source and standby LED light emitting source are switched.And between holding circuit and light emitting source, also be serially connected with a current-limiting resistance R.
The following process of narrating respectively in the utility model lithium cell charging and lithium battery discharge; when the lithium battery of this mine lamp is charged; the special charger (not shown) is connected external power; with the charging socket among plug with wive insertion Fig. 2 of this charger; the electric current of charger flows to lithium battery B by holding circuit and charges; holding circuit can detect charging current, voltage automatically; when reaching 4.2 volts (GB assigned voltage), lithium battery voltage can cut off the input external power automatically; in the present embodiment, the about palpus of this charging process is 4 hours.During the lithium battery discharge; only need gauge tap K is dialled to a point (indicating the sign of major-minor light source position at the mine lamp shell); the electric current of lithium battery flows to gauge tap K by holding circuit; flow to main LED light emitting source D2, D3......D13; form a loop by current-limiting resistance R, holding circuit, cathode of lithium battery again, then main led light source D2, the D3......D13 work of switching on.If the working time surpass continuously certain hour after (as, 10 hours), the brightness meeting descends gradually; If at this moment gauge tap K is dialled point to b; standby led light source is started working; lithium battery circulation overprotection circuit, gauge tap K, standby LED light emitting source D1, current-limiting resistance R, holding circuit flow to the negative pole of lithium battery and form the loop; luminous by standby LED light emitting source D1 specifically; because the power of standby LED light emitting source D1 has only 1/12 of main LED light emitting source power;, for example can return the usefulness of throwing light on the road surface for the worker so but standby LED light emitting source D1 continuous operation for a long time.In the present embodiment, if more than the main LED light emitting source continuous operation certain hour (as 11 hours), then when lithium battery pressure drop to 2.7 lied prostrate, holding circuit produced the action meeting discharge loop is cut off automatically, guarantees lithium battery safety.When the mine lamp that is full of electricity only adopts standby LED light emitting source to throw light on, but then continuous operation was not less than 100 hours.And when charging socket A short circuit or arbitrary LED light emitting source caused short circuit, then holding circuit will produce action power dump, guarantees lithium battery safety; Automatic recovery of power supply then when short dot disconnects.
Because LED lithium battery, holding circuit plate etc. all is little, the in light weight thing of volume, so entire circuit can one encapsulate, a dew has the input hole of charging socket A and group handle of gauge tap K on the lamp shell, other partly all makes Seal Design, so have good waterproof effect; And the utility model has adopted lithium battery to power, and adopts the little LED of power consumption to throw light on, thus the utlity model has in light weight, can repeatedly use, advantage that lighting hours is grown; Because LED is a cold light source, so can not cause gas explosion owing to temperature is too high; In addition, it is more safe and reliable that the design of holding circuit can make the utility model.
