Due to the accelerating process of international elimination of incandescent lamps and the continuous improvement of people's awareness of energy conservation, and the strong background of the state's strong support, domestic LED companies have earned a lot of money in the first half of this year. Today's LED market can be described as a hundred flowers, dragons and snakes mixed, when choosing an LED product , how to choose an LED system will be better. How does the manufacturer's stated tens of thousands of hours of life ensure that it can be achieved? What are the main reasons for making purchasing decisions for LED products? What kind of LED product supplier is trustworthy?
Now LED application technology is not fully mature, but the low-cost competition between LED companies has started in advance. Whether it is LED indoor lighting or LED outdoor street lighting, the phenomenon of low-priced vicious competition is already very obvious. Premature low-price competition will naturally lead to product cuts. So to buy a good product is a vision.
A large number of unrecognized companies have recently entered the lighting market, often publishing performance claims with clear questions and contradictions. This has caused a lot of trouble for consumers. It is difficult for them to know who to trust and what to believe.
The long life and high price of high-quality LED lighting products make the purchase of LED products a long-term investment, which can save a lot of electricity and reduce maintenance costs. However, not all LED systems will perform for many years. A considerable portion of the actual performance of LED products is far below the original statement of the manufacturer.
Faced with such a situation, with the optimistic view on the development prospects of LED, based on our experience in the LED lighting industry, we have summarized some testing standards and shared our experience, our technology and experience with the majority of netizens.

General standard for quality inspection of LED strips
First, the LED light strip appearance inspection standard
The LED lamp has no dirt on the surface of the FPC, and the LED pad has no flux residue.
LED lights with surface tin-free beads.
LED and resistance solder joints are smooth, solder is full, tin-free tip, tin package, less tin.
The LED component package is free from damage, scratches, burns, stains, and the like.
LED no air welding, short circuit, offset, high altitude, reverse polarity, etc.
The resistor has no reverse whitening, empty welding, offset, high height, and monument.
There is no blistering, dirt, discoloration or deformation on the surface of the FPC; there are no damage, breakage, creases, etc. on the line. (emphasis)
The positive and negative polarity of the LED lamp with the Power Supply lead line is the same as the polarity of the LED, and there is no reverse.
The connection point between the FPC segment and the segment is smooth, without tin tip, tin package, short circuit, etc., there is no gap, warpage, displacement, etc. between the FPC.
The soldering point of the connecting terminal is smooth, the solder is full, the tin-free tip, the tin package, and the 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.
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.
Silicone casing waterproof LED lamp with surface silicone casing is free of dirt, scratches, damage, distortion and distortion, and the LED light strip in the casing has no distortion and curvature.
Second, electrical inspection standards
The single-color LED light is energized without chip, and the light is not bright.
RGB lights with power R / G / B groups are detected separately, no light, light and mixed colors.
Each batch of sampling aging experiments was carried out for 8 hours, and no electrical defects were detected.
After the damage test such as bending and vibration, no electrical defects were detected.
After the high and low temperature limit temperature test (-20 ° C ~ 80 ° C), no electrical defects were detected.
Waterproof series LED lamps are rated for protection, and are tested for waterproofing tests to detect no electrical defects.
