- Q: How to judge whether the constant current chip Led flashlight?
- Without the constant current drive board, the whole discharge brightness of the battery is gradually decreasing
- Q: How many volts are the input and output voltages of the charging devices for a regular LED flashlight?
- The input voltage of the charging device for an ordinary LED flashlight is 220 volts alternating current, and the output is 4. 2 volts direct current. LED flashlight charging device, is a capacitor step-down to 6 volts, rectifier diode, into 4. 2 volts direct current into the nickel zinc battery for the bulb to light.
- Q: How to measure the circuit board of LED flashlight with Multimeter?
- 1, before use should be familiar with the multimeter functions according to the object being measured, the correct selection range and test gear, jack.2, when the size of the measured data is unknown, the range switch should be placed at the maximum value, and then switched from a large amount to a small shift, so that the instrument pointer can be indicated at the full scale of 1/2 or more.
- 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 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.

- Q: At present, the LED flashlight commonly used in the market, the built-in lead-acid battery is too bad, can use 4 nickel hydrogen rechargeable battery instead?
- If you want to extend the battery life, the best way is to improve the charging circuit, plus a charge voltage limit, and with the charge, so that the battery life will be long. But it requires professional design and improvement. Now useful lithium battery flashlight, good life. The use of time is also very long, you may consider buying.
- Q: Usually Led flashlight lights specifications and price.
- LED flashlight with beads divided into common cheap strawhat LED and power LED two, strawhat LED general a few cents, high power LED a few dollars to tens of dollars, even hundreds of yuan each, depending on the brand and model.
- Q: What about the voltage of the LED flashlight?
- That resistor is the current limiting resistor,
- Q: What compulsory certification does it require to import LED flashlights in Europe?
- The new ROHS is this stuff, do it very troublesome, especially the cost is too high is also troublesome, I was going to have, now also does not require us to provide the shipment of ROHS, really want to have to do ah. In the domestic market can see, don't say ROHS, it can go through CE is good, and say, generally won't take ROHS to advertise.
