The first set of light emitting diode modules include multiple first type light emitting diode units. The first type fluorescent powder covers on the surface of multiple first type light emitting diode units. The second set of light emitting diode modules include multiple second type light emitting diode units and accessory electronic units. The second type fluorescent powder covers on the surface of multiple second type light emitting diode units. The driver circuit transfers the electricity to the first light emitting diode modules and the second light emitting diode modules to make the first light emitting diode unit and the second light emitting diode unit lighting. Moreover, the accessory electronic unit may affect the relative proportion current between the first set of light emitting diode modules and the second set of light emitting diode modules when the driver circuit supplies the different total current value.
