Electronic device and light-emitting module

摘要

A light-emitting module includes at least one first light-emitting component, at least one second light-emitting component, a first driving component, a second driving component, and a control component. The first light-emitting component is configured to emit a white light having a first predetermined color temperature according to a first power of a first driving signal. The second light-emitting component is configured to emit another white light having a second predetermined color temperature according to a second power of a second driving signal. The control component is configured to separately output the first and second driving signals, and to separately adjust the first and second powers of the first and second driving signals, so as to mix the white lights having the first and second predetermined color temperatures to output a white light having an output color temperature.

1. A light-emitting module configured to emit a white light having an output color temperature, wherein the light-emitting module comprises:
at least one first light-emitting component configured to receive a first driving signal and emit a white light having a first predetermined color temperature according to a first power of the first driving signal, wherein the first light-emitting component comprises:
a first light-emitting unit configured to emit a white light having a first original color temperature; anda first color temperature conversion unit configured to convert the white light having the first original color temperature to the white light having the first predetermined color temperature; at least one second light-emitting component configured to receive a second driving signal and emit a white light having a second predetermined color temperature according to a second power of the second driving signal; a first driving component configured to receive the first driving signal and provide the first driving signal to the first light-emitting component; a second driving component configured to receive the second driving signal and provide the second driving signal to the second light-emitting component; and a control component configured to separately output the first and second driving signals, and configured to separately adjust the first and second powers of the first and second driving signals, so as to mix the white lights having the first and second predetermined color temperatures to output a white light having an output color temperature, wherein a value of the first predetermined color temperature is about 8900K, a value of the second predetermined color temperature is about 5400K and a value of the output color temperature is between 5400K and 8900K.
