The difference between LED linear lamps and LED constant current and constant voltage lamps?

LED Linear Lamps: LED linear lamps are lighting fixtures designed to replace traditional fluorescent tube lights. They are long, narrow fixtures that contain an array of individual LEDs arranged in a linear configuration. LED linear lamps usually operate on a constant current driver, meaning the current flowing through the LEDs is kept constant while the voltage can vary based on the number of LEDs connected in series. The driver ensures that the LEDs receive the appropriate current to operate efficiently and maintain their lifespan. LED linear lamps are typically available in various lengths and wattages to fit different lighting applications.

LED Constant Current and Constant Voltage Lamps: LED constant current and constant voltage lamps are two different types of LED lighting fixtures with distinct operating characteristics.

1. LED Constant Current Lamps: LED constant current lamps require a constant current driver to ensure a consistent current flow through the LEDs. These lamps have a built-in driver that regulates the current supplied to the LEDs. The voltage across the LEDs can vary depending on the number of LEDs connected in series. Constant current lamps are commonly used in applications where precise current control is necessary, such as high-power LED applications or when connecting multiple LEDs in series.
2. LED Constant Voltage Lamps: LED constant voltage lamps operate on a fixed voltage, typically 12V or 24V. They require a constant voltage power supply, often referred to as an LED driver, which regulates the voltage output to ensure a steady voltage supply to the LED lamp. Constant voltage lamps are commonly used in low-power LED applications, such as accent lighting or decorative lighting, where a single LED or a small number of LEDs are connected in parallel.

The main difference between LED linear lamps and LED constant current/voltage lamps lies in their form factor and the way they are powered. LED linear lamps are designed as long, tubular fixtures to replace fluorescent tubes, while constant current/voltage lamps come in various shapes and sizes depending on the specific application. Additionally, LED linear lamps often use constant current drivers to maintain a steady current flow, whereas constant current/voltage lamps have built-in drivers or require external LED drivers to regulate either the current or voltage, depending on the type of lamp.
