when the Triac dimmer 300 adjusts the lamp bead circuit 600, the phase-cut angle detection circuit 510 can detect a dimming signal of the Triac dimmer 300. When the Triac dimmer 300 does not work, the dimming angle of the Triac dimmer 300 is pushed to the maximum, the dimming angle is larger than 75%, at this time, the phase-cut angle detection circuit 510 enables the dimming control chip U5, and the dimming control chip U5 controls the ac-dc conversion circuit 400 through the state switching circuit 520, so that the ac-dc conversion circuit 400 is switched to the WiFi dimming mode. Alternatively, it can be understood that the ac-dc conversion circuit 400 no longer receives the dimming signal of the Triac dimmer at this time, which is the WiFi dimming mode. Meanwhile, the dimming control chip U5 controls the output current of the ac-dc conversion circuit 400 through the WiFi dimming signal output circuit, thereby controlling the brightness of the white light bead and the warm light bead in the bead circuit 600. The dimming control chip U5 further controls the fourth MOS transistor Q4 and the fifth MOS transistor Q5 to be turned on through the optocoupler color temperature transmission circuit 532 and the color temperature control circuit 533, so as to adjust the color temperatures of the white light bead and the warm light bead.
When the dimming angle of the Triac dimmer is smaller than 75%, the dimming control chip U5 sends an electrical signal to the WiFi dimming signal output circuit 531 and the state switching circuit 520, so that the ac-dc conversion circuit 400 converts the Triac dimming mode, that is, the Triac dimmer operates at this time. Meanwhile, the WiFi dimming control circuit does not work.
Furthermore, the dimming power supply compatible with Triac dimming and WiFi dimming is also used together with a mobile phone APP. When the WiFi dimming control circuit does not work, a WiFi dimming interface on the mobile phone APP is changed into grey, and therefore the user is reminded that the WiFi dimming mode is unavailable at the moment. Of course, other devices for controlling the Triac dimming and WiFi dimming compatible dimming power supply, such as a computer terminal, may be used besides the mobile phone APP. In addition, to reminding the user which kind of mode that adjusts luminance is unavailable, be not limited to foretell wiFi and adjust luminance the interface and become grey yet, also can set up to wiFi and adjust luminance the interface and become other colours, to this, the utility model discloses do not specifically limit.
In another embodiment of the present invention, as shown in fig. 10, there is provided a Triac dimming and WiFi dimming method, according to the Triac dimming and WiFi dimming power supply described above, the dimming method includes:
s100: the phase-cut angle detection circuit 510 detects a dimming signal sent by the Triac dimmer 300, and sends the dimming signal to the dimming control chip U5.

S300: the dimming control chip controls the ac-dc conversion circuit 400 through the state switching circuit 520, so that the ac-dc conversion circuit 400 is switched from the Triac dimming mode of the Triac dimmer 300 to the WiFi dimming mode of the WiFi dimming control circuit 500, and the dimming control chip U5 dims the light of the lamp bead circuit 600 through the dimming and toning circuit 530;
s400: the dimming control chip U5 controls the ac-dc conversion circuit 400 through the state switching circuit 520, so that the ac-dc conversion circuit 400 is switched to the Triac dimming mode of the Triac dimmer 300, and the Triac dimmer 300 dims the light of the lamp bead circuit 600.
Specifically, the preset dimming value is a dimming angle value. In this embodiment, the preset dimming value is 75%, and when the dimming angle is greater than 75%, the WiFi dimming control circuit 500 operates, and the Triac dimmer 300 does not operate. When the dimming angle is less than 75%, the WiFi dimming control circuit 500 does not operate, and the Triac dimmer 300 operates.
The utility model discloses a compatible Triac adjusts luminance and the light modulation method of the power of adjusting luminance that wiFi adjusted luminance passes through earlier the phase-cut angle detection circuit 510 detects the dimming signal that Triac dimmer 300 sent, will adjust luminance the signal transmission again to light modulation control chip U5 makes light modulation control chip U5 judge whether the value of adjusting luminance of dimming signal is greater than preset value of adjusting luminance, and according to the judged result, come to switch the Triac mode of adjusting luminance of Triac dimmer 300 into wiFi mode of adjusting luminance; when the WiFi dimming mode is switched, the dimming control chip U5 dims the lamp bead circuit 600 through the dimming and toning circuit 530, and when the Triac dimming mode is switched, the Triac dimmer 300 dims the lamp bead circuit 600 through the ac-dc conversion circuit 400; therefore, the compatibility of Triac dimming and WiFi dimming is realized, and the user experience is improved.
