Q:What brand of LED flashlight is good?

The length of life depends mainly on the power consumption of the light source, the size of the battery power and the current size of the drive circuit. Any brand is the same.

Q:Can you throw the torch directly? Is it LED charging? Will it explode?

You can not throw it away directly. If you want to throw it away, please proceed as follows.

Q:Which brand is LED flashlight good? Recommend it

Look at the aperture, OK, LED flashlight, the aperture is a uniform circle, the difference of LED flashlight spot is divided into yellow and blue, uneven distribution.

Q:Flashlight charging circuit modified LED driver

Not very understanding, but I feel that the landlord of the issue of hybrid, and the 6 string up should be no problem, I do not know the input voltage is how many volts, it should be measured LED input current value, is not high ah?.

Q:Xenon flashlight and general LED what is the difference?

LED is the abbreviation of diode light-emitting, in some semiconductor materials of PN junction, the injection of a small number of carrier carrier and the majority of the extra time will be in the form of light energy to release, thus the power to direct conversion of solar energy. PN junction plus reverse voltage, the minority carrier is difficult to inject, so it does not emit light. The diode, produced by injection electroluminescent principle, is called light-emitting diode, commonly known as LED.

Q:LED flashlight is how to change the weak light, what switch?

The LED flashlight light intensity conversion adjustment is mainly realized by the circuit board, this is the function of the circuit, of course, also have to do a simple conversion through the switch, either way, its operation is completed by the switch, in general, is to realize the conversion of light intensity through the light touch switch function or the switch function.

Q:What is the voltage and current of the 9 head LED flashlight?

When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q:What's the reason for the LED flashlight on?

Unlike a short circuit, it could be a drive board problem. You'd better change it to the seller. The drive board doesn't deserve it

Q:Just bought Led flashlight flashlight, 5 hours charging 9 hours of electricity, and now there is no electricity, but the charger shows full power, but it is not bright, what is the matter?

LED lithium batteries are without memory. Once the battery is dry, the electricity is scrapped. Therefore, when the brightness of the flashlight is obviously lowered, the battery is charged and the power is switched off within one or two hours of the green light. For 9 hours, usually over charge or over release, it is recommended to replace the battery.

Q:What are the categories of LED flashlights?

The number of lamp caps (i.e., LED) ranges from 10 to twenty or thirty, with more than more than 40 lamps. Most of the shell of the torch is made of aluminium alloy. The switch of the torch is set at the tail part, and some are arranged on the side of the front part. The front side switch is more convenient to use. The ignition voltage of high brightness LED about 3V, so the LED flashlight uses three AAA batteries without booster can be directly lit, so the power supply efficiency is high, only a small energy consumption in the current limiting resistor. It should be noted that not the more LED, the better. Qi Jie automotive supplies experts advise, but also pay attention to see if there is a better quality reflector film behind the lamp cover, it can reflect the light scattered by LED, and can improve the brightness of the flashlight 20%~30%. The main disadvantage of the multi burner flashlight is that the focusing effect is not good, and the spotlight effect is not better than that of the ordinary flashlight, so that the light is not bright enough when irradiated on a far distance object.
