Price Principle of Low Voltage 36V1.2m LED Tube
Benwei produces low-voltage 36V1.2m led tube at a price with stable quality and large output, with a daily output of thousands. Large-scale operation and reasonable price. The main specifications are: 12v1.2m led tube, 24v1.2m led tube, etc. Welcome to consult.
Introduction of low voltage 36Vled tube:
What is a low-voltage lamp? Generally speaking, high voltage refers to 110v, 220v, 347v, 277v. Generally, the power supply of LED lamps is these rated voltages. However, in some special occasions, it is closer to the human body. For the sake of safety, low-voltage fluorescent tubes were born. Low-voltage lamps are generally divided into: 12v/24V/36V. That is, 36v lower than the safety voltage. Such lamps are safe at all. So what is the difference between low-voltage fluorescent lamps and high-pressure fluorescent lamps?
1. High-voltage LED fluorescent tube, input high-voltage power supply, when passing through the led power supply, it adopts step-down processing. At the same time, it is a switching power supply. Using the feedback circuit, it can work with a wide voltage such as 85-265v, so that the pulsating alternating current becomes Direct current, supplied to led lamp beads. Because it is a constant current power supply, the current is constant, so the LED lamp beads are also stable. Will not interfere with the grid. protect eyes. If it is EMC, that is electromagnetic interference. The LED tube without electromagnetic interference will not interfere with the surrounding electrical appliances during use. The surrounding electrical appliances do not interfere with the lamp. This is a qualified led tube.
2. Low-voltage led tube, just the opposite, the input voltage is low, and the low-voltage 36v needs to be boosted. The circuit is simpler than the high voltage. After boosting, through chip control, the output current is also constant, and the output voltage changes with the voltage of the LED lamp string. When there are many light strings, the voltage will be high, on the contrary, the voltage will be low. So as to ensure a certain power requirement. The price of 36V1.2m led tube, the power is generally about 18w, and the price is generally more than 30 yuan.
