Q:Why hold a few moving magnets, manual power LED flashlight bulb will shine?
A magnetic magnet is used to move downward, the magnet field line cuts the coil on the periphery of the magnet, and the coil generates electricity to recharge the rechargeable batteries at both ends of the coil, so that the LED bulb emits light.
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 are the parts of a LED flashlight?
First: LEDSecond: BatteriesThird: circuitFourth: barrel, reflector cup
Q:To explore the customer LED flashlight flashlight is what led?
The United States, Germany, Japan imports and so on, different flashlights are not the same.
Q:What's wrong with the LED rechargeable flashlight that has been lit all night long?
According to your question, the problem is that the battery is broken
Q:What are the models of ultra high brightness LED on flashlights?
At present, more LED used on flashlights are mainly two kinds of CREE and lumens.
Q:LED rechargeable flashlight can not charge, but plug in power can be bright, what is the reason?
The battery is broken. The batteries on the LED flashlight are all lead-acid batteries. The charging circuit is a power frequency transformer plus a simple rectifier or a series of plastic capacitor current limiting rectifier. The fatal drawback is that it can not be fully stopped automatically, nor can it be limited by constant current. Several long charging the battery. Charging time is too short, it will also cause battery charge, polar plate sulfide damage. There is no loss detection circuit, the battery power is not automatically cut off the power supply, resulting in damage to the battery discharge. Well, the flashlight is a lithium battery, charger, LED driver circuit, CB and other environmental protection certification. Perfect protection circuit.
Q:How to detect the flashlight LED lamp is good or bad?
Very sure. Both the 200 and diode files can be measured directly, and LED has been doing so. But if you connect together the series resistance measurement, the superfluous. LED is different from ordinary diodes, but not everyone knows nothing about it.This is your hat bright LED, current parameters 20mA, mA of the few chips to judge the quality of light is LED.
Q: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.
Q:Buy a few flashlight LED lamp, directly connected to the 5V electric heating lamp why. How to solve?.
Not limiting directly connected to the 5V, has been lucky not to burn
