FAQ

Rechargeable LED flashlight can not be repaired?

I have repaired more than one, usually screw, and some screws in the decoration, you need to remove the decorations to see

How about the LED rechargeable flashlight bulb flashing?The components are intact and flashing

It seems your flashlight must be six or nine kind of relatively simple head. The LED flashlight is generally used three batteries of seven, no internal protection circuit would be better with a current limiting resistor, but many are not added, the battery voltage when full power will be relatively high, and LED is very sensitive to the voltage, it will cause harm to the LED.

LED flashlight structure and manufacturing method

The principle of LED luminescence is similar. But the difference is, LED is not through the electronic transitions inside the atom to emit light, but by applying a voltage across the PN junction LED, the PN junction itself in a level form (in fact, is a series of energy), then the electrons at this level and jump to the light emitting photons.

Troubleshooting of LED flashlight

Lead acid battery damage, can not charge and discharge, showing plug in order to use

What about LED flashlights and AMC7135, and a better, more practical IC?

As the saying goes, Kaoshanchishan by water draft, we decided the geographical advantages of our development, as Baoji China Titanium City, we have a huge resource advantage, titanium alloy profiles and processing you, shouldn't we ever to concentrate on the development of the. Machining, surface treatment of titanium, the production of raw materials, innovative titanium products we can say ahead of other domestic manufacturers of titanium metal, is only a surface treatment, the seven treatment process we have, in Titanium City and no one.

In the light rechargeable flashlight is how much?

The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.

What's the resistance on the LED flashlight?

LED is a light emitting diode, belonging to semiconductor lighting. A silicon PN section of the pressure drop is 0.7V, a light emitting diode operating current is 10--20mA, the battery general 2 section, voltage is 3V, light-emitting diode is commonly used in parallel

Make a small flashlight with LED lights

I suggest you use the high-power 1W lamp, it will be relatively light, if the demand is not high with a can lighting.
