LED lamp bead parameter interpretation

5050RGB patch LED light bead is widely used in many LED light bead products. 5050RGB patch LED light bead is mainly used in LED soft strip, LED hard strip, LED module, LED backlight, etc.

First, 5050RGB patch LED lamp bead parameters and application

1, 5050RGB patch LED lamp bead is 5mm*5mm*1.6mm, high light intensity (pure white light, warm light slightly smaller). It works at the same voltage as a normal LED, only 3.0-3.4V, with the same current of 60MA.

2. Because 5050RGB patch flexible led strip light parameters determine that he must be a popular LED, so he is often used in high-end civilian energy-saving lamps, car dashboards, LED light belt, mobile phone backlight and buttons, instrument backlight and small volume LED products, LED backlight, switch and sign plane backlight, Caller ID, flash lamp, automobile, audio, indoor display, lighting market.

Two, 5050 patch LED lamp bead types

1, 5050 beads are divided into monochrome white light and monochrome red, green and blue color series, as well as 5050 with IC flash and slow flash and three-color RGB, RGY, RRG, RGBW and other three-color, four-color beads.

Three, 5050 SMT LED lamp bead selection skills

1, product packaging and trademark: a good 5050RGB patch LED lamp beads should have wavelength, drive current, lumen and other basic technical parameters, as well as brand trademarks and relevant certification marks. Regular enterprises can provide corresponding detection data. At present, there are better 5050 lamp beads in the market, including Taiwan Tong Jia, The United States Kerui and Japan Asia.

2, look at the quality of FPC: FPC is divided into two kinds of copper coating and calendered copper. The copper foil of copper coating is protruding. If you look closely, you can see it from the connection between the pad and FPC.

3, look at the solder joint: the regular 5050 lamp bead manufacturers are using SMD patch technology, solder paste and reflow welding process production. Solder joints are smooth. Welding standards can refer to ROHS lead-free welding process (Eu limits the use of hazardous substances)

4, look at the colloid: colloid is generally epoxy resin, with uv resistance and fire retardant price is more expensive, high-quality outdoor lamp beads should be uv resistance and fire prevention.
