LED lamp with appearance and electrical inspection standards
Jan 18, 2019

With the advent of LEDs, lighting design theory is constantly evolving with the advantages of LEDs. LED strips have also been widely used in indoor lighting, building decoration and automotive beauty industries. However, the LED lamp belt market is mixed, and the prices of regular manufacturers and cottage products vary widely. If you know the quality of LED strips from the technical point of view, I am afraid many customers do not have this ability. However, we can initially identify the LED strips according to the following criteria, and basically distinguish the quality.


LED light strip appearance inspection standard

(1) LED strip with FPC surface is free of dirt, and the LED pad has no flux residue.

(2) LED lamps with surface tin-free beads.

(3) LED and resistance solder joints are smooth, solder is full, tin-free tip, tin package, less tin.

(4) LED components are packaged without damage, scratches, burns, stains, etc.

(5) LED no air welding, short circuit, offset, high altitude, reverse polarity, etc.

(6) There is no anti-white, air welding, offset, floating height, and monument. No blistering, dirty, discolored or deformed surface; no damage, breakage, creases, etc.

(7) There is no blistering, dirt, discoloration or deformation on the surface of FPC; there is no damage, breakage or crease in the line.

(8) LED lamp with power supply lead line positive and negative polarity and LED polarity are the same, no reverse.

(9) The connection point between the FPC segment and the segment is smooth, no tin tip, tin package, short circuit, etc. There is no gap, warpage or displacement between the FPCs. The joint between the segment and the segment has a smooth solder joint, a tin-free tip, a tin package, a short circuit, etc., without gaps, warpage, displacement, and the like.

(10) The soldering joints of the connecting terminals are smooth, the solder is full, the tin-free tip, tin package, short circuit, the appearance of the terminal is free from burns, scratches and dirt, and the terminal and the FPC are closely fitted without warping and displacement.

(11) Epoxy waterproof LED lamp with uniform surface glue, no glue overflow, no defects, good surface smoothness and high transparency. No dirt, dust, foreign matter or bubbles.

(12) Silicone casing waterproof LED lamp with surface silicone casing is free from dirt, scratches, damage, distortion and distortion, and the LED lamp strip in the casing has no distortion and curvature.

Electrical inspection standard

(1) Monochrome LED lamp with power supply, no chip is not bright, slightly bright.

(2) RGB light with power R/G/B Each group detects, no light, light and mixed colors.

(3) 8 hours of sampling aging test per batch, no electrical defects.

(4) After the damage test such as bending and vibration, there is no electrical defect.

(5) After the high and low temperature limit temperature test (-20 ° C ~ 80 ° C), no electrical defects were detected.

(6) Waterproof series LED lights with protection level, respectively, waterproof test, no electrical defects

(7) With the advent of LEDs, lighting design theory is constantly evolving with the advantages of LEDs. LED strips have also been widely used in indoor lighting, building decoration and automotive beauty industries. However, the LED lamp belt market is mixed, and the prices of regular manufacturers and cottage products vary widely.
