Q:What is patch LED?
Patch element. Very small, no pins, soldered directly to the circuit board. For example, the keyboard lights in a mobile phone are used in this way.
Q:How does the LED patch lamp differentiate between positive and negative poles?
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.
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches 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.
Q:Patch LED light does not flash, why?
Hit the meter on the buzzer and measure the patch individually. If the flash is a patch, the light goes off.
Q:Patch LED market conditions
Conventional monochrome SMD LED package sizes are 1206 (3215), 1004 (2510), 0805 (2012) and 0603 (1608). Chinese manufacturers can provide a minimum size of 0603, the thickness of only 0.3 mm. A smaller LED of 0402 (1005) is still in trial manufacture
Q:How do led patches measure good or bad?
Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
Q:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
Q:Patch LED beads can be bought in what place?
Many LED packaging plants do patch LED, you can find the relevant manufacturers to contact, or go to the local electronic components market according to your needs
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!!!
