Description
Technical field:
The utility model relates to the LED mine lamp that use down-hole, a mine.
Background technology:
Mine lamp is mine underground labour's a lighting apparatus commonly used, the bilux bulb that original mine lamp adopts, not only power consumption is big, and bulb when using temperature too high, in case glass lamp shade or bulb break just may produce gas explosion.Have cold light source, power saving, not fragile, characteristic such as the life-span is long because LED is a light emitting diode, particularly have higher luminous efficiency, in mine lamp, more and more bring into use.Domestic LED mine lamp is made up of lamp holder and rechargeable battery at present, and lamp holder comprises: cloche, sealing ring, parabolic reflective mirror, lamp socket, lamp housing, power supply line, circuit board, LED king light, secondary lamp plate, secondary lamp.After the LED mine lamp occurred, what use always aspect led drive circuit was constant current drive mode, because the LED mine lamp adopts lithium battery power supply substantially, had disposed charging circuit again, these two kinds of circuit synthesis is arranged on the circuit board, and is positioned in the lamp holder.Charging chip that adopts and match circuit have been realized multistage charging process and dynamic battery internal resistance compensation, guarantee charging effect.But in the process of charging, variations that often raise of the temperature of battery can not the monitoring battery temperature owing to present charging circuit, in time regulates charge parameter, causes that battery temperature is too high sometimes, to causing certain influence the service life of battery.
The utility model content:
The purpose of this utility model provide a kind of can the monitoring battery temperature, regulate the LED mine lamp of charging current parameter.
To achieve these goals, the utility model is made up of lamp holder and rechargeable battery, lamp holder comprises: cloche, sealing ring, the parabolic reflective mirror, lamp socket, lamp housing, the power supply line, circuit board, the LED king light, secondary lamp plate, secondary lamp, the lamp socket fixture is in lamp housing inside, circuit board and LED king light are installed on the lamp socket, the LED king light is positioned in the middle of the bottom of parabolic reflective mirror, secondary lamp is fixed on the secondary lamp plate and is evenly distributed on the top of lamp housing, be furnished with charging circuit and drive circuit on the circuit board, it is that sidewall at battery has fixedly installed a temperature sensor, and the signal output part of temperature sensor is connected to the input monitoring end of charging circuit management chip.
Like this, in charging process, when battery temperature changes, temperature sensor will be timely with the battery temperature status signals, be transferred to the input of charging circuit management chip, after the managing chip integrated treatment, the control and regulation charging current, make battery remain on charged state preferably, avoid the battery temperature to economize too high and cause battery to damage.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a holder structure schematic diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment:
As seen from Figure 1, Figure 2, the utility model is made up of lamp holder and rechargeable battery, and lamp holder comprises: cloche 1, sealing ring 2, parabolic reflective mirror 3, lamp socket 4, lamp housing 5, power supply line 6, circuit board 7, LED king light 8, secondary lamp plate 9, secondary lamp 10.Lamp socket 4 fixtures are in lamp housing inside, circuit board 7 is installed on the lamp socket 4 with LED king light 8, the LED king light is positioned in the middle of the bottom of parabolic reflective mirror 3, and secondary lamp 10 is fixed on the secondary lamp plate 9 and is evenly distributed on the top of lamp housing, is furnished with charging circuit and drive circuit on the circuit board.Charging circuit comprises: managing chip IC1, model are KX640, capacitor C 1, C2, resistance R 1, R1A, R2, R3, R4, R5, R6, diode D1, switch adjustment pipe Q.Battery is VCC, and temperature sensor is TEMP.Charging voltage (5.5V～6.5V) be added on C+, GND to hold, and be connected with earth terminal with chip IC 1 power end respectively, R4, R5 and capacitor C 1 are the charging voltage buffer circuit; Resistance R 1, R1A, R2 and R3 produce electric current entrance management chip IC 1 current comparator end jointly, and wherein R1, R1A, R2 and R3 play the effect of fine setting setting voltage, and R6 plays fine motion and regulates the managing chip setting function of current; Q is a switch adjustment pipe, the control charging process, and its G utmost point inserts chip charging drive end; Sidewall at battery VCC has fixedly installed a temperature sensor, and the signal output part of temperature sensor TEMP is connected to the input monitoring end of charging circuit management chip IC 1.Cell voltage is isolated back access-in management chip IC 1 voltage comparator end through C2; Charging process mainly finishes by precharge, constant-current charge, constant-voltage charge, charging.Drive circuit comprises: king light LED1, and secondary lamp LED2, LED3, LED4, LED5, LED6, LED7, chip IC 2, model are 9926, chip IC 3, model are LM350, resistance R 7, R8, R9, R10, R11, R12, R13, diode D2.King light LED1 drives mainly by chip IC 2, IC3 control, resistance R 7, R8, R9 and resistance R 11, R12, R13 constitute comparison circuit, when cell voltage passes through processing of circuit greater than threshold value 2.8V, the IC3 output produces high level and makes the IC2 conducting, king light LED1 has constant current by work, otherwise do not work, avoid battery to cross and put; Secondary lamp is externally luminous behind the switch conduction, but cell voltage still do not work when being lower than 2.8V, avoids battery to cross and puts.
