Background

LED lamps typically have a 12V/24V supply voltage and a 220V supply voltage. If the power supply voltage is 220V, an external power transformer is not needed, a transformer is already built in the lamp and is directly connected to a 220V power supply, and if the power supply voltage is 12V/24V, a 12V/24V power supply is needed to be connected externally, namely the power transformer, the voltage is reduced from 220V to 12V/24V, the voltage can be generally AC and DC, and the 12V/24V LED lamp can not be directly connected to the 220V power supply.

The transformer of LED lamp passes through the wire and connects LED lamp and power, and can adjust the power that self light can be adjusted to the LED lamp of can adjusting luminance, consequently the transformer of being connected rather than in different illumination intensity, the heat of production is different, so need design one kind can be according to self temperature automatically regulated radiating efficiency's transformer, in addition, because binding post and the wire of transformer expose and get into dust and water stain in the air easily, this can influence the result of use of transformer, so still need the transformer to have dustproof waterproof function.
