precautions for use: storage time: 1.the operation of temperatures and rh are : 5 ~35 ,rh60%. 2.once the package is opened, the products s hould be used within a week. otherwise, they should be kept in a damp proof box with descanting agent. considering the tape life, we suggest our customers to use our pr oducts within a year(from production date). 3.if opened more than one week in an atmos phere 5 ~ 35 ,rh60%, they should be treated at 60 5 fo r 15hrs. cleaning: use alcohol-based cleaning solvents such as isopropyl alc ohol to clean the led. esd(electrostatic discharge): static electricity or power surge will damage the led. use of a c onductive wrist band or anti-electrosatic glove is recommended when handing these led. all devices, equipment and machinery must be properly grounded. (a) recommended circuit. (b) the difference of brightness between led could be f ound due to the vf-if characteristics of led. drive method: led is a current operated device, and therefore, require r some kind of current limiting incorporated into the driver circuit. this current limiting typically takes the form of a current limiting resistor placed in series with the led. consider worst case voltage variations than could occur across the current limiting resistor. the forwrd current should not be allowed to change by more t han 40% of its desired value. circuit model a led led circuit model b ! ligitek electronics co.,ltd. property of ligitek only page 10/11 part no.ldbk9553/t/tr1
