2. circuit: boost circuit, according to the battery used to boost the circuit to a certain value, to meet the requirements of light-emitting diodes, generally about 3V. If it is a lithium battery, there is a step-down circuit, as well as discharge protection circuit.

Is led flashlight used widely?

LED flashlight is a high brightness LED used as a light source. It has the advantages of high brightness and low energy consumption. It is an environmental protection and energy saving product. LED flashlight and flashlight flashlight is the biggest difference is that there is no light, flashlight power and distance, but lighter than flashlight, low energy consumption, use a long time.

About bright flashlight and ordinary LED flashlight choice

The luminous efficiency of high power LED than small power high, under the same current, high power LED light, such as the common CREE R5 (3W) can produce 120lm illumination in the 350mA state, more than 20 5mm LED (parallel, each average current is about 17mA) bright;

What type of battery 5 has the longest time in a LED flashlight?

Flashlight battery life time, mainly depends on the following factors:The size of 1.LED power consumption, which determines the size of the LED flashlight button battery, is certainly used strawhat type LED micro light, low brightness, low power, low power consumption, and 4 batteries of 5 flashlights, should use the high power LED, power consumption may be several times the button battery flashlight. Of course, a short time.2. battery power. The important role of the size of the length of power battery life, power button batteries generally only tens of Ma, and No. 5 battery in general a few hundred Ma, high power Ni MH rechargeable battery, even in the more than two thousand ma. Therefore, the button battery life longer, certainly because LED low brightness, power, small power consumption, not because of the small battery number 5.3. circuit drive current size. The size of the discharge is also very important, if the discharge current is large, then the time is short, the current is small, time is long.Generally speaking, these three factors are the most important. And to more power 5 batteries, or buy a nickel hydrogen rechargeable battery, you can first look at the instructions, the amount of electricity at one thousand or two thousand Ma or more can be.
