Eye Protection Desk Lamp 2835 Spectrum 5000K 28-30lm For Student


Application Introduction:


Stroboscopic refers to the stroboscopic that is obviously visible to the naked eye and the stroboscopic that is invisible to the naked eye. When the stroboscopic speed is beating at a frequency of more than 50 times per second, the naked eye cannot perceive the light stroboscopic. If it can be observed by taking photos with a mobile phone, eye-care stroboscopic removal is to take photos with the mobile phone screen, and there is no sign of stroboscopic. Only the oscillograph can detect that the wave depth is less than 0.03

The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the

Top of package. The pressure to the top surface will be influence to the reliability of the LEDs. Precautions Should be taken to avoid the strong pressure on the encapsulated part. So when use the picking up nozzle,The pressure on the silicone resin should be proper.

Soldering iron:

   When hand soldering, the temperature of the iron must less than 300℃ for 3 seconds.

   The hand solder should be done only one times

SMT Reflow Soldering Instructions SMT:

   Reflow soldering should not be done more than two times ;

   When soldering , do not put stress on the LEDs during heating ;

   The recommended reflow soldering profile as following ;
