Q:What does "1210" mean in patch LED?

1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!

Q: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.

Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?

Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V

Q:Patch LED market conditions

Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.

Q:What is the difference between patch LED beads and LED beads: General

Patch is a LED lamp, 0805, SMD beads 3014, 3528, 2835, 5050, 5630, 5730 and so on.

Q:What is the difference in performance between the LED plug-in and the LED patch?

No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different

Q:SMD LED lamp working voltage?

Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage

Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you

You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.

Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?

3528 single lamp is 0.06W 0.06*60 lamp =3.6W 3528-60 bead is 3.6W/ meters

Q:What are the storage requirements of SMT patch LED (LED)?

Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours? remove the pouch before baking, and do not open the oven door frequently
