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

1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric

Q:Patch LED light does not flash, why?

There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights

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

The ten patch LED lamps are connected in parallel with rated power of 5 watts and voltage 3.3V.

Q:What is patch LED?

Patch LED refers to surface mount LED.The LED is separated from the PCB board in the form of inline and surface mount. Piranha, 3mm lights, and 5mm lights are all pins. While most high-power LED is surface mount, that is, patches. Small power LED also has the form of surface mount such as PLCC-2 and PLCC-4.

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, in what way do I shunt the LED?

LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.

Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?

They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.

Q:What determines the brightness of the patch LED?

The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.

Q: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.

Q: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?

Chip and stent welding methods are: eutectic welding, silver glue fixed, resin insulation and fixed silicone rubber insulation fixedWelding beads: reflow soldering, hot plate welding and manual soldering.
