The requirements for blue and green LED soldering are the same as those for white LEDs. In terms of the level of general white LED soldering, there are such basic requirements. The operation needs to be noted as follows:
1. Always wear anti-static gloves, anti-static wrists, and electric irons must be grounded during production. It is strictly forbidden to touch the two lead pins of white LEDs with bare hands. Because the anti-static of white LED is 100V, and the working humidity on the workbench is 60%-90%, the static electricity of the human body will damage the crystal layer of the LED. After working for a period of time (such as 10 hours), the diode will be ineffective (not lit). ), will be invalid immediately if it is serious.
2. The soldering temperature is 260 ° C for 3 seconds. If the temperature is too high, it will burn out the chip if it takes too long. In order to better protect the LED, the LED colloid and the PC board should be kept at a distance of 2mm or more, so that the solder heat is dissipated in the pin.
3. The normal working current of the LED is 20mA, and the small fluctuation of the voltage (such as 0.1V) will cause large fluctuations in current (10%-15%). Therefore, in the circuit design, different current limiting resistors should be paired according to the voltage drop of the LED to ensure that the LED is in the best working condition. If the current is too large, the LED will shorten the life and the current will be too small to reach the required light intensity.
Generally, the LEDs are separated by color separation, that is, the LED light intensity, voltage, and light color in the same package are consistent, and are indicated on the spectrometer.
Function description
The socket is ordinary converter,with two output 5V2A power USB power supply at the same time,can be very convenient in use electrical appliances and recharge the equipment at the same time,such as digital products like Iphone Ipad,MP3,MP4 etc.The charge apply to full range of international AC output,no-load power consumption less than 0.3W,with short circuit,overload,over-voltage protection,can be convenient for your life and save more energy
Timer Control Time Adgustment
1.Press the power switch 1 time,the 1HOUR LED will light on.The Timer into ON mode,USB and control socket output ON .
2.Continuously press the power switch the LED light on,the Countdown mode and LED light on will cycle change from 1HR,2HR,4HR,6HR,8HR,10HR.
3.Choose you need countdown time mode,the mode LED will lighto on,start countdown until countdown time finish,the control output and USB change to OFF
4.Then the countdown is start,The Time indicate LED will from high to low auto change until Countdown finish off.
Failure analysis:
1.check whether the power supply connection is good
2.check whether the USB cable is loosen
Warning Note:
1.Use indoor and dry location ONLY
2.The load max does not exceed 15A 3600W
