LED lighting market, the low threshold, so some investors do not avoid this "lucrative" projects, resulting in poor quality products flooding the market. If you are a little understanding of LED lighting market, there are ways to identify inferior and superior LED street lamp, produced a regular LED lights produce business and cottage version of the LED lights (at the end of cheap materials, artificial plug, attached to lamp beads, a large number of dead lamp beads, poor power supply capacitors, a serious light failure) is seeing from out of the previous work. Here's to our New Sunshine toward lighting products, for example, talk about how to identify the LED lights by youthful quality of good or bad.

 

Good heat dissipation: From the shell, patch, and power supplies to the circuit board material selection and production process of the unique design of the production process and then to the strict control of each step, have determined that the overall cooling of the lamp to achieve a good cooling effect, to ensure that the LED lamp life.

 

Light is small: Our products have good heat dissipation, with a unique circuit design, in 3 years to ensure the light failure at 5%. High-performance power supply: life can also achieve more than 3 years or 5 years, in extreme conditions, such as 50 degrees above zero, or minus 50 degrees below, using the technology, the same life expectancy can be achieved over 3 years.

 

 

 

 

1, LED light source, mainly to see the light bead chips, the U.S. mainstream CREE, Germany Osram, Taiwan wafer. U.S. CREE, Germany Osram relatively expensive price, cost-effective wafer Taiwan.

 

2, to see work. LED lights work on a regular lamp board dirty very rough, light beads arranged in crooked (partakers plug and patch), plastic line leaks, lens quality is poor.

 

3, the regular LED lights will be used to attach the box with the specifications stated, and light, but also equipped with LED lights or deck connector; and cottage version of the LED lights inside the box there is no such attachments, as they is able to save the province.

 

4, look at solder joints. LED lights produce a formal business produced LED street lamp is the use of SMT chip technology, solder paste and reflow soldering process using produced. Therefore, LED lights on the solder joints than the amount of force will not be smooth and more cylindrical arc spot to the LED from the FPC pad at the extension of the electrode. The cottage version of the LED lights Uneven solder joints, mostly of a welded pin dot wrap with the special circumstances presented different levels of tin tip, which is a typical phenomenon of manual welding.

 

5, see FPC quality. FPC copper sub-deposited copper and the rolling of two, Bonded Copper of copper foil is projecting, and look with the FPC, then the connection from the pad at the seen. Copper is the calendar closely, and even as one of the FPC can be bent and will not show pad wanton shedding phenomenon. If bending over Bonded Copper will show off the pad, when the temperature is too high maintenance can also cause the pad off.

 

6 LED lights to see the cleanliness of the surface. If the process produced by SMT LED lights, the surface cleanliness was very good, do not see the wisdom for impurities and stains. But if the hand-welding process produced Knock LED lights, no matter how clean the surface, would have left traces of dirt and cleaning, while the surface of the FPC will be left over flux and dross.
