The instant disclosure relates to a wall switch base of an electric light, and in particular, to a wall switch base of an electric light with a built-in battery module.
With the development of technology, wireless control of electric lights has become popular. In the existing art, a Bluetooth module is generally disposed in a wall switch base of an electric light, and the alternating current provided by the live wire is converted into direct current for powering the Bluetooth module. Since the power consumption of the Bluetooth module is low, the Bluetooth module can be operated based on the power directly provided by the live wire. However, a WIFI module has a relatively high power consumption and generates heat when powered.
Therefore, in order to overcome the disadvantage mentioned above, the design of a wall switch base of an electric light must be improved.
The main object of the instant disclosure is to provide a wall switch base of an electric light for solving the problem above.
An embodiment of the instant disclosure provides a wall switch base of an electric light including an electronic switch connected in series with the electric light and a switch base electrically connected to the electronic switch. The switch base includes an AC/DC converting module for converting an alternating current into a direct current for output, a charging module electrically connected to the AC/DC converting module for converting the direct current received from the AC/DC converting module into a charging voltage for output, a battery module electrically connected to the charging module for storing and supplying power, and a wireless transmission module electrically connected to the battery module for being operated based on power supplied by the battery module and controlling the electronic switch based on a wireless controlling signal.
To sum up, the wall switch base of an electric light provided by the instant disclosure includes a built-in battery module which is electrically connected to a wireless transmission module, and hence, the wireless transmission module with high power consumption can be operated based on power provided by the battery module. Therefore, the wireless transmission module receives stable power supplied from the battery module instead of receiving power from the live wire.

The accompanying drawings are included to provide a further understanding of the instant disclosure, and are incorporated in and constitute a part of this specification. The drawings illustrate exemplary embodiments of the instant disclosure and, together with the description, serve to explain the principles of the instant disclosure.
Reference will now be made in detail to the exemplary embodiments of the instant disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

The electric light Z has two ends connected to a first wire L1 and a second wire L2 respectively. The first wire L1 can be a live wire or a neutral wire, and the second wire L2 can be a neutral wire or a live wire. In the present embodiment, the first wire L1 is a live wire and the second wire L2 is a neutral wire. One end of the electric light Z is connected to the live wire and the other end of the electric light Z is connected to the neutral wire. The electronic switch S can be used to control the on and off of two ends of the live wire.
The switch base P is electrically connected to the electronic switch S and can be connected parallel with the electronic switch S. As shown in
The AC/DC converting module 10 can be an AC-DC converting circuit or module, and the AC/DC converting module 10 can obtain an alternating current from the live wire and convert the alternating current into a direct current. For example, the AC/DC converting module 10 can convert an alternating current of 220V or 110V into a direct current for output. The AC/DC converting module 10 can include a transformer, a rectifier or a filter, etc.
The charging module 20 can be a charger IC and is electrically connected to the AC/DC converting module 10. The charging module 20 can receive direct current from the AC/DC converting module 10 for converting the direct current into charging voltage for output. Specifically, the charging module 20 can include a battery charging circuit 21 and a battery voltage detecting circuit 22. The battery charging circuit 21 is configured to charge the battery module 30. The battery voltage detecting circuit 22 is configured to detect the voltage of the battery module 30, and when the voltage of the battery module 30 is lower than a predetermined voltage, the battery voltage detecting circuit 22 controls the battery charging circuit 21 to charge the battery module 30.
The battery module 30 can be a chargeable battery module and is electrically connected to the charging module 20 for storing and supplying electrical power. Specifically, the battery module 30 can have one or a plurality of lithium-ion batteries for receiving the charging voltage output by the charging module 20. Therefore, the charging module 20 can charge the battery module 30. For example, when the voltage of the battery module 30 detected by the charging module 20 is lower than 3V, the battery module 30 is pre-charged; when the voltage of the battery module 30 detected by the charging module 20 is between 3V and 4.2V, the battery module 30 is charged under a constant current; and when the voltage of the battery module 30 detected by the charging module 20 is larger than 4.2V the battery module 30 is charged under a constant voltage until the battery module 30 is full-charged.
The wireless transmission module 40 is electrically connected to the battery module 30 and hence, the wireless transmission module 40 can be operated under (powered by) the power provided by the battery module 30. Therefore, the wireless transmission module 40 does not need to consume the power provided by the live line. The wireless transmission module 40 can be operated under electrical power provided stably by the battery module 30. In addition, the wireless transmission module 40 can be configured to control the electronic switch S based on a received wireless control signal. Specifically, the wireless transmission module 40 can include a WIFI module 41 and/or a Bluetooth module 42 which can be operated separately and can be used to receive control signals. The wireless control signals can come from a portable device M such as a mobile phone or a tablet. In addition, the wireless control signal can come from a wireless access point A (WIFI AP). The portable device M can connect to the wireless transmission module 40 through the wireless access point A. Based on the design of the wireless transmission module 40, the wall switch base of the electric light 100 can be connected to the portable device M in wireless form, and when the wireless control signal output by the portable device M is corresponded to a control demand of “on”, the electronic switch S can be used to set the on/off state of the live line to be “on”. When the wireless control signal output by the portable device M is corresponded to a control demand of “off”, the electronic switch S can be used to set the on/off state of the live line to be “off”. Therefore, the on/off state of the electric light Z can be controlled by controlling the on and off the live line.
The brightness adjusting module 50 is electrically connected to the wireless transmission module 40. The brightness adjusting module 50 can adjust the output brightness of the electric light Z according to the wireless control signal received by the wireless transmission module 40. The brightness adjusting module 50 can be a PWM (Pulse Width Modulation) brightness adjusting module for adjusting the output brightness of the electric light Z according to the duty cycle of the PWM signal.
In summary, the wall switch base of the electric light 100 provided by the embodiments of the instant disclosure includes a built-in battery module 30 which is electrically connected to the wireless transmission module 40. Therefore, a high power consumption wireless transmission module 40 can be operated under power provided by the battery module 30 rather than power directly provided by the live line.
The above-mentioned descriptions represent merely the exemplary embodiment of the present disclosure, without any intention to limit the scope of the instant disclosure thereto. Various equivalent changes, alterations or modifications based on the claims of the instant disclosure are all consequently viewed as being embraced by the scope of the instant disclosure.
