What’s the difference between led drives 20-40 and 60-80?
1. No problem. This is backward compatible, you can choose a large one, not a small one. It’s just that the cost is higher, in general, the greater the power, the higher the price.
2. There is not much difference between the two. Basically, they can be driven as long as they can drive 40 watts of 20 watts and 24 watts.
3. Pcs usually represents the quantity in the order. I can understand that there are 60 to 80 LED lamp driver power supplies in front of you.
4. The driver of the LED chandelier first depends on whether the voltage coverage includes your original voltage, and then the high-power one can replace the low-power one, but the price may be that the lamp is brighter than before, but its life is shorter than before.
5. The voltage adapts automatically with the actual Vfs of the load. For example, the output of the driver is 330mA, and the Vf of a single LED is 3V, that is, a single LED is 1W. This driver can drive 20-24 LED light strings in series, the current is stable at 330mA, and the voltage may be 60V, 63V, 66V, 69V, 72V, depending on the number of LED.
Can the 40 ’54W led ceiling lamp driver be replaced by 60′ 80W?
The driver of the LED chandelier first depends on whether the voltage coverage includes your original voltage, and then the high-power one can replace the low-power one, but the price may be that the lamp is brighter than before, but its life is shorter than before.
Sure. Yes, but the LED lamp will be used for a short time, and it may dim or go off in a few days or months, because the driving power is too large, too much over the rated power, resulting in a short life of the bulb.
Can not replace each other, the output voltage range is too large, completely do not coincide, can not work properly, may also damage the led lamp board.
Not universal, the general driver itself with a certain power consumption, all post-equipped drivers are recommended to be more than two watts. Look at me, id. I specialize in integrated ceiling appliances, you can buy my drive, the failure rate is only 0. 5%. Summer is coming, and all the 30-50 yuan led light drivers on the market are beginning to break down.
LED drive power supply. Big ones can take the place of knowing. The small power cannot replace the big one.
Most of the 1W incandescent lamp 10: 18 lm/W,LED light source is about 90: 130 lm/W. The luminous flux of 80W incandescent lamp is 800-1000 lumens, which can be replaced by about 9W LED bulb.
Is the wattage of LED driving power corresponding to that of LED lamp?
1. It is obvious that there will be a problem if the light is used in terms of W number. For users, the most important indicator of LED drive power is whether its output is consistent with the needs of lamps and lanterns, not just power. Output includes: output voltage, output current and its accuracy. The output power is the output voltage multiplied by the output current.
2. It is not universal. Led drivers need to be equipped with different led lights before they can be used, so not all led drivers are universal. Now the types of led lamps on the market are also very complete, so once the bulb is broken, it certainly needs to be replaced.
3. The brightness of LED lamp is related to the wattage. The higher the wattage of LED, the higher the lumen value and the greater the natural brightness.
4. P=UI I=P/U, divide the wattage of the lamp by 12V voltage (assuming the LED lamp is 12V operating voltage), what is obtained is the working current.
5, generally speaking, the power (wattage) of LED lamps and lanterns is calculated by the power of LED chips (light sources), that is, 10 watts of LED lamps and lanterns, the light source should be 10W or.
