Q:Cree flashlight lamp which is the best.
CREE was founded in 1987, is the United States listed companies (1993, NASDAQ: CREE), the leading global manufacturer of famous LED epitaxy, chip, packaging, LED lighting solutions, compound semiconductor materials, power devices and RF integration in the industry and.
Q:What's the resistance on the LED flashlight?
If 5 heads, the working current is 5*20mA=100mA=0.1A, the voltage at both ends of the resistor is 3-0.7=2.1V, so the resistance power is 2.1V*0.1A=0.21W., so the power of the resistor is 1/4W.From this, you can calculate the resistance power of 7 heads and 10 heads
Q:Batteries removed in a rechargeable LED flashlight. What kind of battery is this? You can't charge it now. What electrolyte do you need?
4V lead-acid batteries! Pry off the cover plate, remove the rubber cap, and fill the distilled water with a syringe, just as the electrode plate has just been submerged! After restoration, you can charge as usual!
Q:How about the LED rechargeable flashlight bulb flashing?The components are intact and flashing
LED and damaged only replace the bad light emitting unit. The electronic market can go to buy a few and your flashlight like LED, very cheap, the only bad welding off, replaced it, the remaining few backup, because will bad. A long time you will find LED the brightness of a, this is the voltage to blame
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:What are the parts of a LED flashlight?
1. LED led for lighting
Q:LED lamp with what method from the welding of aluminum substrate nondestructive down (T6, flashlight)
10WL2 lamp can be heated with aluminum heating plate, and then welding parts of the painting WEWELDING M51MFP Wei Odin paste, then to aluminum substrate welding.
Q:To explore the customer LED flashlight flashlight is what led?
Their beads are imported.
Q:The LED flashlight battery is a little bit. Why is it very low?
Take apart, look at the driver, measure the current
Q:What is a LED flashlight used for?
LED torch. Good light. Durable good. I usually use it for carving. And photography outside fit the needs. And go out and look at the warehouse
