LED spotlight isolation transformer and LED spotlight

The utility model discloses an LED spotlight isolation transformer which comprises a framework and a magnetic core, wherein the magnetic core comprises two half magnetic cores, and the two half magnetic cores are relatively buckled for clamping a coiling groove arranged on the framework. The LED spotlight isolation transformer also comprises a shell, wherein a cavity matched with the magnetic core and used for holding the magnetic core is arranged on the shell. The LED spotlight isolation transformer adopting the arrangement that the two half magnetic cores are used for clamping the framework ensures that the framework is in an enclosed space, thus the electromagnetic interference is prevented, and the accuracy of the output voltage is improved. The additionally arranged shell is used for replacing the traditional peripheral isolation adhesive tape, on the basis of reading the safety requirement, the role of primary and secondary isolation is played, the LED spotlight isolation transformer is more attractive.
