Analysis of LED driver power supply issues
LED drive power supply 9901 circuit is composed of electronic components, including semiconductor components, resistance, ED is a cold light source, the working junction temperature can not exceed the limit, and a certain amount of surplus is left in the design. The design of the entire lamp should consider the appearance of beauty, easy installation, light distribution, heat dissipation and many other aspects, to seek a balance point in many factors, so that the overall lamp is good. The development time of LED lamps is not long, there is not much experience that can be learned, and many designs are constantly improving.

Analysis of Misunderstandings in Charging Methods of Lithium Battery Chargers and Precautions
To deal with the charging method of new batteries, the first three main ones that are officially spread are charged for more than 12 hours to activate the battery" However, this kind of statement is accurate? What about the error?~~ The mystery is wrong~~
Introduction to the Use of Lithium Battery Chargers
Lithium battery chargers are chargers specifically designed to charge lithium-ion batteries. Lithium-ion batteries have high requirements for chargers and need to protect circuits, so lithium battery chargers usually have high control precision, and can charge lithium-ion batteries with constant current and constant voltage.
Maintenance methods for lithium battery chargers
First, before the lithium battery leaves the factory, the manufacturer activates the treatment and pre-charges, so the batteries have surplus power, the newly bought mobile phone battery is a lithium-ion battery, then the first 3~5 times of charging is called the adjustment period, should be charged for more than 14 hours, to ensure that the activity of lithium ions is fully activated.
