DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 6 As shown, a technical solution provided by the present invention is:

[0035] A smart LED light bulb with dimmable light and Bluetooth control, such as Figure 1 As shown, the smart LED bulb of the present invention comprises the following main components: an LED lamp body (1), a dimming circuit (3), a color temperature adjustment circuit (4), a Bluetooth module (2), a control circuit (5), an intelligent learning module (6), an environmental perception module (7), an energy efficiency management module (9) and a health monitoring module (8). The components are electrically connected and cooperate with each other to realize the functions of intelligent dimming and color temperature adjustment. The Bluetooth module (2) is responsible for establishing wireless communication with a mobile device, receiving a control signal sent by a user through an application, and transmitting the status information of the bulb to the application. The control circuit (5) serves as a core control unit, receives control instructions from the Bluetooth module (2), and realizes brightness and color temperature adjustment of the LED lamp body (1) through the dimming circuit (3) and the color temperature adjustment circuit (4). The dimming circuit (3) realizes brightness adjustment through PWM (pulse width modulation) technology, and the color temperature adjustment circuit (4) adjusts the color temperature by changing the light emission ratio of the warm light LED (101) and the cold light LED (102). The environment perception module (7) continuously monitors the external light intensity and sends the monitoring data to the intelligent learning module (6) and the energy efficiency management module (9) for adjusting the light. The intelligent learning module (6) is used to record and analyze the user's usage habits, predict the user's light requirements through data analysis, and dynamically adjust the brightness and color temperature. The energy efficiency management module (9) provides energy-saving mode and optimizes the brightness and color temperature of the bulb based on the power consumption monitoring data. The health monitoring module (8) dynamically adjusts the light based on the user's physiological state by connecting with devices such as smart bracelets and smart watches.

[0036] Example 1: Figure 2 As shown, when the user manually adjusts the brightness and color temperature of the light bulb in the application on the mobile device, the application generates a corresponding control instruction and sends it to the Bluetooth module (2) via Bluetooth. After receiving the instruction, the Bluetooth module transmits the control signal to the control circuit (5). The control circuit adjusts the PWM signal of the dimming circuit (3) according to the instruction, thereby controlling the brightness of the LED lamp body (1), and at the same time adjusts the light emission ratio of the warm light LED (101) and the cold light LED (102) in the color temperature adjustment circuit (4) to achieve a change in color temperature. For example, when the user adjusts the brightness to 50% and selects a color temperature of 3000K, the light bulb adjusts the brightness to 50% and emits warm white light, which is suitable for reading or leisure at night.

[0037] Example 2: Figure 3As shown, the smart LED bulb is connected to the smart mobile device via a Bluetooth module (2) to achieve remote control and networking functions. Specifically, the Bluetooth module (2) uses Bluetooth Low Energy (BLE) technology and supports the Bluetooth Mesh protocol to achieve networking and data synchronization between multiple bulbs. The user scans and identifies all nearby smart LED bulbs in the application of the smart mobile device, and the application establishes a device control list based on the unique ID of the bulb (e.g., the MAC address of the device).

[0038] During use, the application can pre-set multiple scene modes, such as "cinema mode", "reading mode" and "party mode". When the user selects a specific scene mode, the application sends the brightness and color temperature parameters in the scene mode to the master bulb node through the Bluetooth module (2). After the master node bulb receives the control signal, it broadcasts the control signal to all slave node bulbs using the Bluetooth Mesh protocol. After the Bluetooth module of each slave node bulb receives the control signal from the master node, it immediately stores it through the local cache module and synchronously executes the control command, thereby achieving synchronous adjustment of brightness and color temperature.

[0039] Example 3: Figure 4 As shown, the intelligent learning module (6) of the smart LED bulb can automatically adjust the brightness and color temperature within a specific time period by recording and analyzing the user's historical operating habits. After the intelligent learning module establishes the user's preference model by recording and analyzing the user's historical operating habits, when a specific time (such as 10 o'clock in the evening) arrives, the intelligent learning module will send an automatic adjustment signal to the control circuit (5). The control circuit (5) transmits the adjustment signal to the dimming circuit (3) and the color temperature adjustment circuit (4), and adjusts the brightness and color temperature accordingly. For example, the system automatically lowers the brightness to 20% and sets the color temperature to 3000K to create a comfortable evening atmosphere. Experimental data shows that 80% of users reported that the system's automatic adjustment reduced manual operations.

[0040] Example 4: Figure 5 As shown, the health monitoring module (8) is connected to the smart bracelet via the Bluetooth module (2) to receive the user's physiological data, such as heart rate and activity intensity, in real time. When it is detected that the user's heart rate drops and the activity intensity decreases, the health monitoring module determines that the user may enter a sleep state and sends an adjustment instruction to the control circuit (5). The control circuit (5) gradually lowers the brightness to 10% and adjusts the color temperature to 2700K to provide warm sleep light. For example, in this case, the light bulb automatically adjusts to a suitable brightness and color temperature to help the user fall asleep better. In experimental tests, 78% of users reported that their sleep quality improved.

[0041] Example 5: Figure 6 As shown, when the system detects that the external light has increased, the brightness of the bulb is automatically reduced to save energy. The environmental perception module (7) monitors the external light intensity in real time. When the light intensity exceeds the preset threshold, the energy efficiency management module (9) will start the energy-saving mode and send a command to reduce the brightness to the control circuit (5). The control circuit (5) gradually reduces the brightness of the LED lamp body (1) through the dimming circuit (3). At the same time, the energy efficiency management module feeds back the power consumption change information to the application program, allowing the user to view the energy consumption in real time. For example, when it is detected that the light increases during the day, the brightness of the bulb will automatically decrease to 20%-30% to reduce unnecessary energy consumption. Experimental data shows that the energy-saving strategy reduces household energy consumption by 15%-20%.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
