Important parameters and purchasing skills of 5050 SMD LED lamp beads

1. Color rendering index

The size of the color rendering index directly determines the gorgeousness of the color of the Lamp Beads. The higher the color rendering index, the better the color rendering LED light strip.

2. Pay attention to the soldering temperature

Pay attention to the welding temperature and welding frequency of the product. At present, the common method on the market is spot welding, and the welding temperature is about 260℃.

Three, look at the performance characteristics

There are many subdivision types of 5050 SMD LED Lamp Beads. According to the color, there are single color, multicolor, etc., according to the characteristics, there are fast flashing and slow flashing, so you need to choose according to your actual needs High-power LED.

5050 SMD LED Lamp Bead purchasing skills

1. Product packaging and trademarks

good 5050RGB Smd Led Lamp Beads should have basic technical parameters such as wavelength, drive current, lumens, as well as 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 Nichia Lamp Beads 5050.

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 manufacturer are produced by SMD chip technology, using solder paste and reflow soldering process. 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 with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor lamp beads should resist ultraviolet and fire.
