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

The voltage needs to be determined according to the product specification, usually 3.1 - 3.5V

Q:Patch LED light does not flash, why?

Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low

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?

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.

Q:What determines the brightness of the patch LED?

Lamp brightness level itself, is also in the rated current situation, its brightness

Q:0603，0805，1206，3020，3528，5050，355 what is the current and voltage of these patch LED? Please give advice!

SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.

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

Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.

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:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!

The welding speed and welding time because certainly give light foot heat, so the speed must be fast, tin wire and tip with better, while heating to tin iron head, avoid heating time is too long.

Q:How many volts is a single LED on the LED patch band?

3V or so, generally three, a group plus a resistor, power supply with 12V

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!!!
