LED lamp voltage X DRIVER Answered

Hello my friends,

What about the voltage, Is the driver that operates according to the voltage capacity of the bulb (20-26v) or is the lamp that operates according to the capacity of the driver (20-36v)? The voltage of which one acts according to the other? Can I use a lamp of any voltage since this voltage is understood the ability of the driver (20-36)? the driver is the same amparage and constant current.

Thank you a lot.

There is no such thing as the "voltage capacity" of an LED. What you are reading is the EXPECTED forward voltage drop when it is running at the design CURRENT. So what is that ? Your driver makes the voltage happen when it drives the constant current.

What Rick said, and my electrical engineering definition of

A bulb refers to a glass enclosed filament light (about 1000 usable hours ) or gas plasma fluorescent ( about 10,000 usable hrs ) lighting device.

LEDs are SOLID STATE totally enclosed in plastic resin ( about 100,000 usable hrs ) and LED <=> Light-Emitting-Diode

LEDL = Light-Emitting-Diode Lamp is sort-of kind-of like clumsy.

:LEDs are current driven and need a constant current supply. Given enough current the LED will pull as much as it can until it burns out. This is 1 good reason for using the correct power supply.
