There are many lights: LED lights with flexible, LED light bar, LED rainbow tube, can be called the light bar or light band, I'll talk about the method of choice lights with flexible bar:
Look at this lamp with the FPC, is the board, and now many businesses in order to save costs, the use of single-sided copper to do, so the lights with a long time, severe fever, affect the LED life, a single panel is only one side can be seen to the line, the back (no LED This surface) is smooth, the color is uniform, the second surface of the panel has a double line, there are lines where the color is dark, hand feels obviously feel thick
Look at work, light beads are generally arranged vertically, with joints on both sides of the lamp, solder joint full, shiny, poor Conversely, if the solder black, said it was a long time later, especially horizontal, it is easy Weld, false welding high NPL ratio
See light beads, the DC voltage regulator adjusted to about 6-8V, each lamp micro-light, but relatively uniform, this lamp beads consistency is better, there is a difference of few bright light beads few little dark that, in particular, 5050 lamp beads, lamp beads inside a three chips each normal lighting, if there is no light, or uneven brightness is defective
Bending, the lights around the finger, normal is still normal lighting, poor folded into the camber lamp beads or sealing off resistor.
