1. Look at the signs on the lighting fixtures. Generally, reliable LED line lamp manufacturers will put labels in front of the original lighting fixtures to remind the actual main parameters of the goods. We can see the working voltage of the line lamp according to the signs.
2. What to do without identification? There is no mark on the lighting fixture to indicate how much the working voltage is. If the lighting fixture is transparent glue, when the electronic devices inside the lamp arm can be clearly seen, it can be distinguished according to the total number of LED beads, resistors, capacitors and other electronic devices. Then, the flashing condition of the lighting fixture can be detected from low to high working voltage. During the period, some special tools for electricity measurement can be used to assist in detection. If the electronic components inside the lamp arm cannot be seen clearly in the appearance, it is necessary to disassemble the lighting fixtures for inspection.
Generally speaking, the LED lamp beads used for LED line lamps have a single bead working voltage of 1.8-3v, and the general current will be controlled between 18m A and 50mA. For different color soft integrated ICs, the working voltage of each LED lamp is different. The pure color long bright line lamp is DC24V, and the externally controlled fine color line lamp has six sections of DC24V, eight sections of DC24V, sixteen sections of DC12V, and 32 sections of dc9v.
