LED\u30c9\u30e9\u30a4\u30d0\u30fc<\/a> are essential components used to regulate the power supplied to LED lights. They convert alternating current (AC) from the power supply to a direct current (DC) that LEDs can use. The primary function of a driver is to ensure that the LEDs operate efficiently while maintaining consistent brightness and color.<\/p>\n

Constant voltage drivers supply a steady output voltage (typically 12V or 24V) to the LED<\/a> fixtures. They allow LEDs to operate at a predetermined voltage level. This type of driver is ideally suited for LED strips and fixtures that can handle variations in current. Since multiple LED units can be connected in parallel, constant voltage drivers are preferred in situations where longer runs of LED strip lighting are required.<\/p>\n
