Does the lamp strap connection need the rectifier?
The conventional LED high-voltage lamp band connection must be connected to the rectifier, the market is 220V is the AC output, and the LED light belt requires DC power to be stable and not to flash. The function of the rectifier is to convert AC to DC If it is a low pressure 12V or a 24-v patch, it will require the DC transformer to work properly
Don't need The ballast is an old-fashioned fluorescent lamp that can be used for high voltage breakdown on fluorescent lamps. The ballast is heavy and inefficient. New lighting fixtures have eliminated the ballast. The new lighting lamps adopt LED high-energy energy-saving lamps, which affect the voltage current and heat dissipation problem of LED life. The power supply part is the constant pressure constant flow module, the technology is more mature, the lamp bead heat is done well, can be used for a long time. If the lamp band does not have a power supply, you can replace it with a switching power supply.
When the lamp is connected to the power source, it can be lit normally. The power supply is the switch power supply, the lamp band and the power supply are not rectifier, and the rectifier is not needed.
