FAQ

Patch LED beads can be bought in what place?
SMD LED lamp is now very popular, mainly because of long service life, but also rarely appear dead lights or dark, but there are many defects exist
How many volts is a single LED on the LED patch band?
The single LED on the LED patch band is around 3.3V.LED light emitting diode, which is a nonlinear component, its operating voltage (tube pressure drop) is also different: ordinary red LED about 1.5 V; ordinary green LED about 1.8 V; bright white LED up to 3.3 V or so.
Patch LED market conditions
With good market expectations for the future status of SMD LED, all the major manufacturers have launched their own SMD LED development planning and prototype products, all of a sudden, SMD LED market showing a flourishing and lively atmosphere of contention of a hundred schools of thought.
What, in what way do I shunt the LED?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you
Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?
The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.
LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?
Of course, the reflow soldering is generally divided into three sections of six principle of oven temperature is 150 degrees, 190 degrees, 220 degrees, with a PC lens products can not reflow soldering, PC deformation at 150 degrees, can be heated by a soldering paste on the heating plate.
What are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
