1, led energy saving, but do not know how to change the light source, if you want to change it, you have to change the entire lamp.
2, energy-saving lamps, relatively power-consuming, but easy to replace
How to choose LED ceiling lights, I hope to help you.
1. There are a lot of LED ceiling lamp chips. Instead of listening to the shopping guides of various lighting stores and bombarding you with a lot of chip knowledge, you might as well choose from the beginning, the 5050 chip, the other chips are not considered, so you Just compare prices, it is not easy to be "huyou". And the 5050 chip is currently recognized as one of the chips with the highest energy efficiency, relatively mature technology and the largest application scale. The so-called 5050 chip is a chip with a length of 5 mm and a width of 5 mm. Another example is the 3528 chip, which is a chip with a length of 3.5 mm and a width of 2.8 mm.
2. Select to drive the LED ceiling lamp with "time-delay protection" function. One characteristic of this driver's lamp is that there will be a short delay of a few tenths of a second after the power is turned on. This is the better driver. Compared with ordinary cheap LED drivers, the difference is that this type of driver is equipped with a transformer. The transformer converts the AC power to DC power and then supplies power to the LED chip, so there will be a "delay" when power is applied; The cheap LED driver uses a simple capacitor to step down the voltage, and the lamp lights up at the instant of power-on, without "delay".
To sum up, you need to buy 5050 chip LED ceiling light with "time-delay protection" function.
