Nowadays, LED lighting becomes more and more popular. Whether for under-cabinet lighting at kitchen, wardrobe lighting, home theater, advertising display or ambient mood lighting etc., SMD LED is a good choice.
SMD LED gives high brightness while it has lower power consumption than of a normal LED light tubes (e.g. dip led) and traditional light bulbs. See its features below:
Small Size: SMD LED light source is a very small and light chips enveloped by epoxy resin.
Low Power Consumption: Generally, the voltage per SMD LED is 2-3.6V, current 0.02A-0.03A. It uses very low voltage and current. Power consumption is very low, just equals to 1/8 of incandescent light, 1/4 of traditional light.
Long Life Span: Under proper current and voltage condition, the life span of SMD LED can reach 100,000 hrs. Compared with the other LED tubes(like Dip LED),the optical decay reduce from 10% to 5% in 1000hrs. Produced by Automatic equipment, via heat emitting technical process, the life span of SMD LED is longer.
High Brightness: Mainly adopted 3528 and 5050 SMD high brightness chip, single SMD LED over 5.5lm/1800MCD.
As above, we have mentioned about SMD 3528 and 5050. What do they mean and what is the difference between the two? Let's see the following:
Theoretically, SMD5050 is 3 times brighter than SMD3528.
