Nowadays, there are thousands of "brands" of floodlights in the LED lighting market, and the quality of each "brand" is also uneven. Consumers often find that the floodlights installed outdoors are burned out, so what is the problem that causes the LED floodlights to burn frequently? The floodlight manufacturer Xinyuanhui will answer for you.
There are two main types of led flood lights burned: the driving power of the lamps is burned, and the LED lamp beads are burned.
1. The most common reason for the burning of the driving power supply is the wrong voltage connection, because the flood light has high voltage AC220V and low voltage 24V and 12V. When the low voltage flood light is connected to the high voltage, the driver and light source will be burned.
2. There are two factors for the lamp bead to burn out: the voltage supplied to the lamp bead is too high, and the working current of the lamp is too high.
Our commonly used LED lamp beads have rated voltages of 3V, 6V, and 9V. When the actual working voltage of the LED lamp beads of the flood light is too high, it will directly break down the semiconductor inside the lamp beads, and the LED flood light will not light up instantly.
The difference is that the current is too high. When the current of the lamp bead is too high, the light decay of the lamp bead will be accelerated very quickly. The direct manifestation is that the floodlight will dim in a short period of time after use, and eventually it will not light up.
Therefore, when we say that the floodlight is burned, we should find out the reason for the burning of the lamp, so as to avoid repeated problems when selecting it later. If you want to know more about the product details of the flood light, you can consult the flood light manufacturer Chongqing Xinyuanhui Photoelectric Technology Co., Ltd.
