- Q:Why does my LED flashlight get a whole fever?
- Main causes of fever: LED flashlight is made of high power LED lamp. High power LED can emit strong light during the work time, but also fever soon, but because it is a LED chip using imported brands, it can resist high temperature, usually 100 degrees the temperature has been down no problem.
- 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:High power flashlight LED lamp is 1W, want to use mobile phone battery when 4.2V is connected to electric drums!
- As for the big resistance associated with rated voltage of LED bulb. Assuming the 3.3V, the 1W current is about 0.3A.The voltage on the resistor is 4.2-3.3=0.9V, the current is 0.3A, and the series resistance is about 0.9/0.3=3 ohms.Assuming LED lamp voltage rated voltage is 3V, current of about 0.33A 1W.Resistor voltage is 4.2-3=1.2V, current 0.33A, about 1.2/0.33 = 3.64 OHM Series resistor.
- Q:Simple LED flashlight schematics, principles and components?
- The basic principle of flashlight flashlight: by the luminous body, battery, circuit, shell, reflective ring, a circuit chamber, switches and other components, the basic principle of the current from the battery, and then reaches the circuit and through the circuit to adjust the voltage and current, and then output to the luminous body, for lighting.
- Q:Accord LED charging flashlight, the process of charging open, light on it out
- It is recommended to find a new flashlight! It's hard to buy accessories yourself!
- Q:Led the flashlight doesn't work. What's wrong with it?
- First, the rechargeable battery is damaged, there is no voltage.Two and IED damage, but the possibility is very small, can not all damage.Three 、 each contact part has the open circuit and the broken circuit place. The circuit doesn't work. Check it carefully and be sure to find out why.
- Q:LED flashlight MH7303 how to achieve explosive flash function, there are circuits as follows, but that is, can not achieve detonation flash!
- This is written through the program, the control lights power on and off to achieve flash, flash explosion is only a high frequency.
- Q:How to measure the circuit board of LED flashlight with Multimeter?
- When measuring the resistance of a circuit, the power supply of the circuit under test must be cut off and the live measurement shall not be carried out.
- Q:Does the LED flashlight battery burn the bulb?
- No, but the drive panel might
