LED soft light with no light cause analysis - (AddTime :2013-01-04)

Flexible 200W led Flood light lamp belt after many tests and checks, or there will be not the phenomenon of light. Investigate its reason, has the following kinds:

1, flexible 200W led Flood light lamp with the packing of the protection is not perfect, cause in the process of transportation collision and damage of the lamp bead.
2, flexible 200W led Flood light lamp with virtual welding, the welding point in the process of transportation vibration caused by solder joints fall off and bring about light not bright.
3, flexible 200W led Flood light lamp with solder quantity is little, solder joints are easy to fall off
4, flexible 200W led Flood light lamp with soldering quality is bad, flexible 200W led Flood light lamp belt in the bending process of solder joints are easy to produce embrittlement, falls off phenomenon
5, flexible 200W led Flood light lamp belt when installation bending Angle is too large, cause flexible 200W led Flood light lamp with solder joints with copper foil separation and cause is not bright
6, flexible 200W led Flood light lamp with excessive squeeze when installation products, lead to flexible 200W led Flood light lamp with chip damaged or solder joint deformation off without light 7, flexible 200W led Flood light lamp with PCB resistance welding layer thickness, welding, soldering and circuit board cannot fully fuses in together, is also a kind of virtual welding.
8, flexible 200W led Flood light lamp belt can't distort when installation, if distortion causes 200W led Flood light soft light fall off of the solder joints and cause is not bright.
