- Q: Led strong flashlight batteries, how are they true and false?
- There is no true or false, haolai, lead electric lithium, lithium electric lead two voltage is high, full of lithium 4.2V, lead 4.6V, also connected to the load voltage, voltage drop of battery differential
- 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: About bright flashlight and ordinary LED flashlight choice
- Light and electricity are contradictory, the higher the brightness, the LED drive current is larger, the costs of electricity, to make a compromise in brightness and life time, should be used in high power LED high luminous efficiency and make it work in the high efficiency region;
- Q: To see how the parameters of LED flashlight bulb?
- Mainly to see the use of beads is domestic or imported, what brand, what model.
- 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: 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: Use LED lights and cell phone batteries to make flashlights?
- It depends on what LED is, if strawhat micro light LED, it depends on a few LED lights, and then the calculation, if the power of LED 3-5W, it can also direct drive in general, but for security reasons, can add a constant current voltage stabilizing circuit.
- Q: What about the voltage of the LED flashlight?
- That resistor is the current limiting resistor,
- Q: Does the LED rechargeable flashlight require 3C certification?
- The so-called 3C certification, that is China compulsory product certification system, the English name China, Compulsory, Certification, English abbreviation CCC.
- Q: What compulsory certification does it require to import LED flashlights in Europe?
- RoHS is an directive of the European Union. If the products are exported to the EU or Japan, they should comply with ROHS, otherwise they will be fined and criminal penalties will be imposed. So, if you want to export, be prepared. To avoid unnecessary losses. Many manufacturers have abandoned the EU market because they are not in line with rohs.
