The controversy between LED fluorescent lamp 3014 and 3528 lamp beads is endless
The specifications of 3014 lamp beads are forward current=30mA, voltage=2.8-3.6V, color rendering index=65-85, luminous flux=10-12LM, power=0.1W, life>50,000 hours, size=3.0(long)×1.4 (Width) × 0.8 (thickness) mm.
The advantages of 3014 lamp beads: small size, the development direction of lamps is light, thin, and small. Compared with other LEDs, SMD LEDs are thinner and more convenient in design. You can know from the name of 3014. Compared with ordinary SMD lamp beads, one of the advantages of SMD light source 3014 is its small size; 3014 lamp beads have low light decay, low thermal resistance and good thermal conductivity; thermal resistance is 40°C/W (usually 3528 on the market is 160 ℃/W), and the LED is tested at room temperature, which is better than the general patch; the cost is low, compared with the market 3528/3020, the number of 3528 pieces is more, compared with the cost of the entire lamp, the 3014 has an absolute advantage. It is a better choice for LED lighting fixtures.
The specifications of 3528 lamp beads are forward current=15-30mA, voltage=2.8-3.6V, color rendering index=75, luminous flux=7-8LM, power=0.06w, life>50,000 hours, size=3.5(long)× 2.8 (width) mm.
Advantages of 3528 lamp beads: low light decay. After the LED works, 20MA will normally continue to light up, and the brightness will gradually increase, to about 1500 hours, the brightness will increase by 12%; 10000 hours, the light decay will be less than 25%; the maximum patch can pass The current is 40MA, normal 20MA, 30MMA lighting does not affect the light decay; high brightness, color zone concentration, large angle, bottom thermal resistance, ultra-low light decay technology, long life.
