Parameter interpretation of LED lamp beads
Among the many LED lamp bead products, 5050RGB SMD LED lamp beads are widely used. 5050RGB SMD LED lamp beads are mainly used in LED soft light strips, LED hard light strips, LED modules, LED backlights, etc.
1. Parameters and applications of 5050RGB SMD LED lamp beads
1. 5050RGB SMD LED lamp beads are 5mm*5mm*1.6mm, with high light intensity (pure white light, warm light is slightly smaller). Its working voltage is the same as that of ordinary LEDs, only 3.0-3.4V, and the current is also the same 60MA.
2. Since the parameters of 5050RGB SMD LED lamp beads determine that it must be a popular LED, it is often used in high-end civilian energy-saving lamps, automobile dashboards, LED light strips, mobile phone backlights and buttons, instrument backlights and Products that require small size LEDs, LED backlights, flat backlights for switches and signs, caller ID, flashlights, automobiles, audio, indoor displays, and lighting fixtures markets.
2. Types of 5050 SMD LED lamp beads
1. 5050 lamp beads are divided into single-color white light and single-color red, green and blue color light series. There are also 5050 with IC fast flash and slow flash and three-color in-one RGB, RGY, RRG, RGBW and other three-color and four-color series. Lamp beads.
3. Tips for purchasing 5050 SMD LED lamp beads
1. Product packaging and trademarks: Good 5050RGB SMD LED lamp beads should have basic technical parameters such as wavelength, drive current, and lumens, as well as brand trademarks and related certification marks. Regular companies can provide corresponding testing data. Currently, the better 5050 lamp beads on the market include Tongjia from Taiwan, Creat from the United States, and Nichia from Japan.
2. Look at the quality of FPC: FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad board is protruding. If you look closely, you can see it from the connection between the pad and FPC.
3. Look at the solder joints: The lamp beads produced by regular 5050 lamp bead manufacturers are produced using the SMD patch process, using solder paste and reflow soldering processes. The solder joints are smooth. For welding standards, please refer to ROHS lead-free soldering process (EU restricts the use of hazardous substances)
4. Look at the colloid: The colloid is generally epoxy resin, which is more expensive with anti-ultraviolet and fire retardant agents. High-quality outdoor lamp beads should be anti-ultraviolet and fireproof.
