Description

With two joint rechargeable battery energy-saving LED flashlights

Technical field

The utility model belongs to electronics and LED applied technical field, is about one two joint rechargeable battery energy-saving LED flashlights.

Background technology

Operating current >=the 240mA of conventional two batteries incandescent flashlight, incandescent flashlight battery is not durable, and it was not long will change battery, and this brings very burden and waste to user.And only having 45 ~ 60mA with the flashlight operating current that LED makes, the power that ordinary incandescent lamp flashlight consumes is about 5 ~ 6 times of LED flashlight power, and the brightness of incandescent flashlight luminescence also can not show a candle to LED flashlight.

Have that volume is large to overcome common batteries incandescent flashlight, the large and defect that brightness is low of power consumption, use two described in the utility model saves rechargeable battery energy-saving LED flashlight, two joint rechargeable battery energy-saving LED flashlights have employed special LED drive integrated circult, 2 high brightness white light-emitting diodes can be lighted with two joints No. 5 rechargeable batteries, it have electricity economize, easy to use, long service life, its life-span is about longer 100 times than ordinary incandescent lamp bubble, the night lightings such as it is applicable at home, camp, out on tours.

Below describe use two described in the utility model in detail and save the correlation technique content that rechargeable battery energy-saving LED flashlight relates in implementation process.

Utility model content

Goal of the invention and beneficial effect: have that volume is large to overcome common batteries incandescent flashlight, a large and defect that brightness is low of power consumption, use two described in the utility model saves rechargeable battery energy-saving LED flashlight, two joint rechargeable battery energy-saving LED flashlights have employed special LED drive integrated circult, 2 high brightness white light-emitting diodes can be lighted with two joints No. 5 rechargeable batteries, it have electricity economize, easy to use, long service life, its life-span is about longer 100 times than ordinary incandescent lamp bubble, the night lightings such as it is applicable at home, camp, out on tours.

Technical characteristic: with two joint rechargeable battery energy-saving LED flashlights, it comprises 3V DC power supply, ultra low differential pressure current stabilization circuit and light-emitting component LED1 ~ LED2, it is characterized in that:

Ultra low differential pressure current stabilization circuit: the model that ultra low differential pressure flow straightener IC1 selects is AMC7135, ultra low differential pressure flow straightener IC1 positive source connection circuit positive pole VCC, ultra low differential pressure flow straightener IC1 power cathode connection circuit ground GND;

Light-emitting component LED1 ~ LED2 selects two highlighted white light-emitting diodes, highlighted white LED 1 positive pole and highlighted white LED 2 positive pole connection circuit positive pole VCC, highlighted white LED 1 negative pole and highlighted white LED 2 negative pole connect the output of ultra low differential pressure flow straightener IC1;

3V DC power anode is by mains switch SK connection circuit positive pole VCC, and 3V DC power cathode is connected with circuit ground GND, and 3V DC power supply uses two joint 5#, capacity is more than 1000mAH nickel-hydrogen chargeable cell.

Circuit working principle: AMC7135 is a kind of 350mA ultra low differential pressure flow straightener.It can reach lightness stabilized, increase the effect of battery gross output with the High Power LED of 350mA constant current output promotion 1 ~ 3W.Need not any outward element, and there is the functions such as output short-circuit, open-circuit-protection and overtemperature protection.Its ultra low differential pressure, low quiescent current characteristic, extend the rechargeable battery operating time.

Accompanying drawing explanation

Accompanying drawing 1 is the embodiment circuit working schematic diagram that the utility model provides a use two to save rechargeable battery energy-saving LED flashlight.

Embodiment

According to the circuit working schematic diagram and the accompanying drawing explanation that save rechargeable battery energy-saving LED flashlights shown in accompanying drawing 1 with two, and according to the annexation in each several part circuit described in utility model content between components and parts, and the components and parts technical parameter described in execution mode requires that carrying out enforcement can realize the utility model.

The technical parameter of components and parts and selection requirement thereof

IC1 is ultra low differential pressure flow straightener, and the model selected is AMC7135, and it is encapsulated as 3 pin, and its operating voltage range is 2.7 ~ 6V;

The highlighted white light-emitting diode of LED1 ~ LED2, requires that diameter is that ￠ 5,2 technical parameters are consistent; Because the technical parameter discreteness of some light-emitting diode is very large, as: under normal voltage, its forward reverse resistance is inconsistent, make its working current value deviation comparatively large, use lumination of light emitting diode brightness large and the light-emitting diode that operating current is less than normal so will note selecting;

DC is two joint rechargeable batteries, can select two joint 5#, capacity is more than 1000mAH nickel-hydrogen chargeable cell, or uses 1 capacity to be more than 1000mAH lithium battery.

Circuit production main points and circuit debugging

Because of fairly simple with the circuit structure of two joint rechargeable battery energy-saving LED flashlights, one piece of AMC7135 integrated package is only had in circuit, as long as the electronic devices and components performance generally selected is intact, and the components and parts annexation to specifications in accompanying drawing 1 is welded, physical connection line and welding quality are through carefully checking correctly, and circuit of the present utility model does not need to carry out any debugging and can normally work;

It should be noted that flashlight is long-time not between the operating period, need to take out rechargeable battery, corrode electric torch circuit to prevent rechargeable battery leakage and cause fault.

Circuit components layout of the present utility model, circuit structure design, its shape and size etc. of outward appearance are not all key technologies of the present utility model; because not affecting the utility model specific implementation process; neither the claimed technology contents of the utility model, therefore do not illustrate one by one in the description.
