RY3730 constant current drive LED light

RY3730 constant current drive LED lamp, using RY3730 to achieve constant current drive, small size, LED uses 2835 package, single 60ma, 6 series in series.

The BOM has been inspected and can be purchased directly based on the BOM

Product introduction

The LED lamp implemented using the RY3730 solution uses 2835 packaged LEDs, 6 in series and 1 in parallel, and uses constant current drive.

Application scenarios

Used for daily lighting and as fill light for shooting.

product advantages

1. Use constant current drive to extend LED life
2. All original parts are SMDs, eliminating the need for plug-ins and preventing plug-in pins from damaging other objects.
3. The supply of original parts is stable and can be produced for a long time.

Other things to note

LED welding requirements are high, and it is generally not recommended to use a soldering iron for welding. It is recommended to purchase a heating table + solder paste.

The feedback resistor of the constant current drive currently uses a 5.1Ω precision resistor. If there is a higher brightness requirement, the resistance can be reduced, but the minimum should not be less than 4.7Ω (which happens to be the maximum current in the LED manual)

Due to the use of fiberglass boards, the lamp beads generate serious heat when used. It is recommended to purchase a heat sink to prevent burns.
