What are high-quality and high-reliability LED products?

Due to the accelerating process of phasing out incandescent lamps internationally and the increasing awareness of energy conservation among the public, coupled with the strong support of the state, domestic LED companies still made a lot of money in the first half of this year. Today's LED market is full of flourishing companies. When choosing an LED product, how can you choose a better LED system? How can the manufacturer ensure that the tens of thousands of hours of life claimed by the manufacturer can be achieved? What are the main reasons for making purchase decisions for LED products? What kind of LED product supplier is trustworthy?

LED application technology is not yet fully mature, but the low-price competition among LED companies has already started. Whether it is LED indoor lighting or LED outdoor street lighting, the phenomenon of low-price vicious competition is already very obvious. Premature low-price competition will naturally lead to cutting corners on product quality. So it takes vision to buy good products.

A large number of unverified companies have recently entered the lighting market, often issuing performance data claims that are clearly questionable and contradictory. This has caused great confusion for consumers, who find it difficult to know who and what to trust.

High-quality LED lighting The long life and high price of the product make the purchase of LED products a long-term investment, which can save a lot of electricity bills and reduce maintenance costs. However, not all LED systems will perform consistently over the years. A considerable number of LED products actually perform far below the manufacturer's initial claims.

Faced with this situation, with optimism about the development prospects of LED, based on our experience in the LED lighting industry, we have summarized some testing standards to share our experience, technology and experience with the majority of netizens.

LED light General quality inspection standards

1. Appearance inspection standards for LED light strips

There is no dirt on the surface of the LED light strip FPC, and there is no flux residue on the LED soldering pad.

The LED light strip surface is free of tin beads.

LED and resistor solder joints are smooth, solder is full, no tin tip, tin package, less tin.

LED components The package has no damage, scratches, burns, stains, etc.

LED has no empty soldering, short circuit, offset, floating, reverse polarity, etc.

The resistor has no whitening, empty soldering, offset, floating, or tombstone.

The FPC surface has no blistering, dirt, discoloration, or deformation; the circuit has no damage, breakage, or creases. (Key point)

LED light strip Power supply The positive and negative polarity of the lead wire is consistent with the LED polarity, and there is no reverse.

The solder joints between FPC segments are smooth, without tin tips, tin packages, short circuits, etc. There are no gaps, warping, displacement, etc. between FPCs.

The solder joints of the connecting terminals are smooth, the solder is full, there are no tin tips, tin bags, or short circuits, the terminal appearance has no burns, scratches, or dirt, and the terminals and FPC fit tightly without warping or displacement.

The surface of the drip glue waterproof LED light strip is dripped evenly, without glue overflow and defect, and the drip glue surface is smooth and transparent. There is no dirt, dust, foreign matter and bubbles.

The silicone sleeve waterproof LED light strip surface silicone sleeve is not dirty, scratched, damaged, deformed or twisted, and the LED light strip inside the sleeve is not twisted, deformed, or arched.

2. Electrical inspection standards

When the single-color LED light strip is powered on, there is no chip that does not light up or is dimly lit.

When the RGB light strip is powered on, each R/G/B group is tested separately, and there is no phenomenon of not lighting, dim lighting or mixed colors.

Each batch of samples is subjected to 8-hour aging test to detect any electrical defects.

After bending, winding, vibration and other destructive tests, no electrical defects were found.

After the high and low temperature extreme temperature resistance test (-20℃~80℃), no electrical defects were detected.

The waterproof series LED light strips are tested for waterproofness according to their protection level to ensure that there is no electrical defect.
