Question:

Does the laptop power adapter replace the LED ceiling lamp drive power (18 W) is feasible? Thank you.

LED ceiling lamp drive power can not help, want to know whether the use of laptop power adapter is feasible. Thanks a few teachers. If not, with mobile phone charger transformation ok? How to change

Answer:

First of all, I personally think that the other two answers did not say the point. The idea that you want to replace is not feasible under normal circumstances (if you are familiar with the parameters of the LED and the connection, then the number of cases can be used instead of the case), because the notebook power adapter is a DC voltage source Both constant voltage output. While the LED (LED work when the forward voltage drop will change) power supply is the need for constant current power supply. So in essence it is not a power supply.
What are the drive power parameters? Mainly the output voltage, the output current. Adapter power supply if it is not enough light is not bright, the phone charger voltage is generally 5V, the current is generally 500-1000mA. The voltage is too much current too light and then easy to bad, so to directly replace the words is not feasible.
