Q:What are the categories of LED flashlights?
There are two types of manual charging LED flashlights. One type of flashlight is an active cylindrical magnet that can slide in a coil when it is operated by hand, the coil generates current, and the battery is charged after rectification, and a LED light is lit. The other is the first drives the generator to rotate with the hand pressing flashlight, the flashlight of the lower price, but this kind of power LED flashlight manual most of the reliability is not good.
Q:What are the parts of a LED flashlight?
The shell, including the shell, reflector bowl, switch, etc.!
Q:How to make the simplest 1.5 volt LED energy-saving lamp, flashlight?
Use the 1.5v-3v battery box to connect the bulb. The bulb has no positive and negative poles. It's that simple.
Q:Is led flashlight damaged easily?
No, LED itself is very durable
Q:LED flashlight instead of direct plug in power lighting
Change block power well, flashlight power is DC low voltage power supply, home power is 220V AC power supply is fundamentally different
Q:How does the LED flashlight determine the intensity of illumination?
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.
Q:How many lumens is the 35W LED flashlight?
Hello, LED light effect is generally around 90, 35W, then about 3150 lumens.Of course, this is an estimate. It may not be that high35W's flashlight is bright, brighter than the two 100 watt incandescent light bulb.
Q:An ordinary LED flashlight, 3W, uses only 1.5V common batteries, and now uses 3.6V's lithium batteries,
Must use, must be removed or short circuit to the original, but also the series resistance of 25 Ohm, although this effect is still not ideal, the use of lithium battery voltage decreased slightly, due to the resistance divider, LED not very bright. The best of the constant current circuit (resistance will dynamically adapt to changes). An electric charge of LED after work much longer.
Q:Why should a bright flashlight use a 3.7V battery, and why not?
High voltage lithium battery, the working voltage of 3.7V, and the driving voltage of LED is about 3.3V, and the driven part of the pressure drop, a lithium battery just right. If the dry battery, NiMH, requires 3 day series, if you want a single 1.5V driver LED to boost driver, boost large current driving cost is high, and the copycat flashlight, in order to reduce costs, with the current limiting resistor in series, the voltage of the battery must be higher than the working voltage of LED.The rest is the inherent characteristics of lithium battery, high energy, light weight a lot.
Q:Rechargeable LED flashlight
The capacitor is usually used as polyester capacitors, reactance, and lead-acid rechargeable battery series, impedance matching, to control the voltage, is a simple and cheap charging means, you disconnect the battery directly measured will certainly produce a very high voltage.
