Driving circuit and lamps

A lamp, comprising:

• a driving circuit, comprising:
• a first bridge circuit, wherein the first bridge circuit is coupled to an AC voltage source to output a first voltage, and the first bridge circuit comprises a first positive input terminal, a first negative input terminal, a first positive output terminal and a first negative output terminal;
• a second bridge circuit, wherein the second bridge circuit is coupled to the AC voltage source to output a second voltage, and the second bridge circuit comprises a second positive input terminal, a second negative input terminal, a second positive output terminal and a second negative output terminal, wherein the second negative output terminal and the first negative output terminal are coupled to the same ground potential;
• a first protection device coupled between the second positive input terminal and the AC voltage source;
• and
• a second protection device coupled between the second negative input terminal and the AC voltage source;
• a light emitting module receiving the first voltage and enabled by the first voltage;
• and
• a bluetooth module receiving the second voltage and enabled by the second voltage.
