1. The 5050 lamp beads are divided into monochromatic white light and monochromatic red, green and blue color light series, and 5050 with IC fast flash and slow flash and three-color combination of RGB, RGY, RRG, RGBW and other three-color and four-color Lamp beads.
How to choose 5050 SMD LED lamp beads
1. Product packaging and trademarks: Good 505ORGB SMD LED lamp beads should have basic technical parameters such as wavelength, driving current, lumens, and brand trademarks and related certification marks. Formal enterprises can provide corresponding test data. At present, the best 5050 lamp beads on the market are Taiwan Tongjia, American Kerui, and Japan Muya.
2. Look at the quality of FPC: FPC is divided into two types: copper and rolled copper. The copper foil of the copper-clad board is protruding. If you look closely, it can be seen from the connection between the pad and the FPC.
3. Look at the solder joints: The lamp beads produced by the regular 5050 lamp bead manufacturers are produced by SMD chip technology, using solder paste and reflow soldering processes. The solder joints are smooth. The welding standard can refer to the ROHS lead-free welding process (the EU restricts the use of hazardous substances>
4. Look at the colloid: The colloid is generally epoxy resin, and the price is more expensive with anti-ultraviolet and fire retardant. High-quality outdoor lamp beads should be anti-ultraviolet and fireproof
