Lamp diagnostic system and method

The invention relates to a lamp, in particular to a lamp diagnosis system and method.

At present, the lamps on the market can be installed with two kinds of lamps, one is an LED tube and the other is a fluorescent tube. If the LED tube is compared with a fluorescent tube, the LED tube has the advantages of energy saving and environmental protection, but two The light is emitted according to different principles. The traditional fluorescent tube needs to convert the commercial power into a high-frequency alternating current through a ballast to drive the fluorescent lamp. The LED tube is driven by a DC power source, so the early LED tubes are The built-in power supply directly converts the commercial power into the DC power supply required by an LED lighting module in the LED tube. However, in this way, the ballast needs to be removed from the lamp, and the foot of the lamp is directly connected to the mains power supply.

Although LED lamps are popular in every household, and the new generation of LED tubes are compatible with the ballast, they can directly convert the high-frequency AC power of the ballast into the DC current required by the LED, thus saving installation.
