1.5050 single-core red light patch lamp beads are an upgraded substitute for three-core products;
2.5050 three-core SMD lamp beads cause the phosphor to deviate from the center of the chip due to thermal expansion and cold contraction, resulting in blue light leakage, resulting in uneven color temperature and color. The problem of spot movement, 5050 single-chip SMD lamp beads solve the problem of three-core 5050 SMD chromatic aberration;
3.5050 three-chip SMD lamp beads are packaged with low-power chips, and 5050 single-chip SMD lamp beads are packaged with high-power chips. Package; with the increase of the chip, the LED light decay tends to zero, which prolongs the service life of the LED;
4.5050 single-core LED SMD lamp beads greatly improve the reliability of the LED; the 5.5050 single-chip SMD lamp beads have low thermal resistance Based on the 5050 three-core LED chip, which contributes to the service life, heat dissipation and light efficiency of the light-emitting diode; SMD lamp beads have high cost performance and stability, and were the dominant direction of the market in the past, and are currently mainly aimed at high-end customers.
