Claim of US Patent No. 10,893,589

1. A LED bulb comprising:a first set of light emitting diode module comprising a plurality of first type light emitting diode units, and a first type fluorescent powder covering a surface of the plurality of first type light emitting diode units;
a second set of light emitting diode module comprising a plurality of second type light emitting diode units and a resistor, a second type fluorescent powder covering a surface of the plurality of second type light emitting diode units and the resistor, the first type fluorescent powder having a different light characteristic from the second type fluorescent powder so that a first spectral characteristic of the first type light emitting diode units is different from a second spectral characteristic of the second type light emitting diode unit; and
a driver circuit for supplying electricity to the first set of light emitting diode module and the second set of light emitting diode module so as to drive the first type light emitting diode units and the second type light emitting diode units to emit light, and the resistor determining a relative electrical current ratio for currents received between the first set of light emitting diode module and the second set of light emitting diode module when the driver circuit supplies a different total current value.
