1. Look at the solder joints. The LED light strips produced by regular LED light strip manufacturers are produced by SMT patch process, solder paste and reflow soldering process.

Second, look at the quality of FPC. FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC.

Third, look at the cleanliness of the LED strip surface. If the LED light strip produced by the SMT process, the cleanliness of the surface is very good, and no impurities and stains can be seen

4. Look at the chips and production processes used for LED lights. You can't tell the difference with your eyes. You should use aging equipment and testing equipment. If you put LEDs from several manufacturers on the aging machine, use high current to age for 24 hours or longer. Time, you go to measure the LED brightness of several manufacturers, and see which LED has the least attenuation of luminous intensity, and the quality with the least attenuation is the best.

LED smart street light with face recognition and automatic alarm

If the child accidentally gets lost, just through the LED smart street lights densely distributed in the city, he can perform face recognition, track the location and quickly retrieve it. If you think this is just a scene in a technology film, you are wrong. .

This magical smart street light: an LED light on the top looks no different from an ordinary street light. The difference is that a high-definition camera is added on the top of this smart street light, and an electric bicycle and an electric car are connected to the bottom of the street light pole. The charging pile and the middle of the street light pole are also embedded with a high-definition display screen that can watch live TV and send Wi-Fi.
