FAQ

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.
What determines the brightness of the patch LED?
The current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.
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.
0603,0805,1206,3020,3528,5050,355 what is the current and voltage of these patch LED? Please give advice!
LED patch: 0603, 0805, 1206, 1210, 5050. The 0603: conversion to metric is 1005, that of the LED element length is 1.0mm, width is 0.5mm. The trade is abbreviated as 1005, and the English name is 0603. The 0805: conversion to metric is 2125, that of the LED element length is 2.0mm, width is referred to as the 2125 inch 1.25mm. industry, it is 0805. The 1206: conversion to metric is 3216, that of the LED element length is 3.2mm, width is 1.6mm. The trade is abbreviated as 3216, and the English name is 1206. The 1210: conversion to metric is 3528, that of the LED element length is 3.5mm, width is 2.8mm. The trade is abbreviated as 3528, and the English name is 1210. The 5050: This is a metric called, said that the LED element length is 5.0mm, width is 5.0mm. Industry abbreviation 5050
How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you
The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
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
Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!
When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.
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
