LED lighting products are divided into high-voltage and low-voltage LED LED, due to their different strengths, depending on the application environment and therefore need to choose a different LED lamps. High voltage LED lighting applications What are the advantages :
( 1 ) high light efficiency. It was a small series of multi-core chips made ??by actual test light efficiency with ordinary light sources with higher wattage 5-10 %.
( 2 ) low power requirements . Prices and the high failure rate of the power supply is the most important issue in recent years has been hindered development of the industry , and high-voltage LED it, has inherent advantages , through a small number of sources with a linear constant current driver can achieve the perfect LED efficient and safe stability.
( 3 ) linear power combined with cost savings . Speaking of which some may say that the low efficiency of linear constant current power supply , in fact, depends on how you go with , appeared on the market a lot of linear constant current driver IC performance are pretty good since the past two years, I have tested a linear constant current IC called RY8201 its efficiency up to 0.9. Due to the small volume of linear constant current IC , peripheral components and less power-driven absolute advantage can be part of making directly above the PCB , thus eliminating the need for warehouse space and mounted power supply equipment ( also on the absolute power to do ) , and other related links, so that highlights the advantages of cost control , warehousing, production , delivery and other costs.
Superiority ( 4 ) light source section. Since the light source is a conventional low VF value only after the passage of more than N string and used welding high labor costs and poor welding product after another, thus affecting the production capacity and bring a lot of secondary costs.
( 5 ) the light fades . As traditional light strings N by N and the way made ??known, inconsistent VF light and together, will result in the load on each power source is different , resulting in premature aging or dead parts of the light source lamp , resulting in the whole lamp light fades acceleration. The high-pressure lamp beads multi-string approach is adopted , easy to solve these problems.
