Description

Technical Field

[0001] This utility model relates to the field of lighting system technology, and in particular to an underwater control system for automatically adjusting color temperature. Background Technology

[0002] Underwater lighting is an indispensable piece of equipment for underwater operations, underwater exploration, and underwater recreation, providing illumination for the underwater environment. However, the brightness and color of ambient light vary greatly at different water depths. To achieve optimal lighting, the color temperature of the lighting fixtures needs to be adjusted accordingly.

[0003] Currently, underwater lights with color temperature adjustment require users to manually control the lights or operate them by pressing buttons or knobs to adjust the brightness, color temperature, and mode. However, underwater photography often requires capturing the moment, and users may miss the best shooting time due to insufficient time to adjust the lights, causing them great inconvenience.

[0004] Therefore, it is necessary to design an underwater lighting system that automatically adjusts the brightness and color temperature of the light by detecting the water depth in order to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an underwater control system that automatically adjusts color temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An underwater control system for automatically adjusting color temperature includes a microcontroller, a water pressure sensor, a battery, a power supply circuit, a white light group, and a warm light group. The battery is connected to the power supply circuit, the white light group, and the warm light group. The power supply circuit is connected to and powers the water pressure sensor and the microcontroller. The water pressure sensor is connected to the microcontroller. The microcontroller is connected to the white light group and the warm light group through an LED driving circuit.

[0008] Preferably, the microcontroller is connected in series with an electronic screen, and the electronic screen is connected to and powered by a power supply circuit.

[0011] By adopting the above solution, this utility model identifies the current water depth of the user through a water pressure sensor, and then controls the brightness of the white light group and the warm light group respectively by relying on the LED driving circuit according to the water depth. After adjusting the brightness of the white or warm light, the color mixing is achieved, thus realizing automatic color temperature adjustment. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] like Figures 1 to 4 As shown in the figure, this embodiment provides an underwater control system for automatically adjusting color temperature, including a microcontroller, a water pressure sensor, a battery, a power supply circuit, a white light group, and a warm light group. The battery is connected to the power supply circuit, the white light group, and the warm light group. The power supply circuit is connected to and powers the water pressure sensor and the microcontroller. The water pressure sensor is connected to the microcontroller, and the microcontroller is connected to the white light group and the warm light group through an LED driver circuit. The microcontroller in this embodiment can be an ESP32-C6FH4 model.

[0020] In this embodiment, the battery provides the overall power supply, and the power supply circuit is used to convert the battery voltage (16.8V) into the 3.3V voltage required by components such as the microcontroller and water pressure sensor. When the machine is turned on, the water pressure sensor detects the current water pressure value in real time, and the detected parameters are sent to the microcontroller. According to the corresponding internal program settings, i.e. the threshold settings, whenever the water pressure reaches a threshold, the microcontroller outputs the corresponding PWM signal, thereby relying on the LED driver circuit to control the brightness of the white light group and the warm light group. By mixing white light and warm light, color temperature adjustment is achieved.

[0021] Furthermore, to facilitate users in obtaining information such as current lighting conditions or water depth, the microcontroller in this embodiment is connected in series with an electronic screen. The electronic screen is connected to and powered by a power supply circuit, so that the electronic screen can be used to display corresponding data, such as water depth, color temperature parameters, etc.

[0022] Furthermore, the LED driving circuit described in this embodiment can be adopted as follows: Figure 2 As shown, it includes MOSFET Q3. The gate of MOSFET Q3 is connected to the microcontroller and receives the PWM signal from the microcontroller. The sources of MOSFETs Q3 and Q4 are grounded through two resistors R13 and R14. Another LED driving circuit is composed of MOSFET Q4 and resistors R15 and R16.

[0023] Furthermore, the power supply circuit for this embodiment can adopt, as follows: Figure 3The circuit structure shown mainly consists of a step-down chip U1. To conserve energy by preventing real-time operation during idle periods, a wake-up circuit is connected between the power supply circuit and the battery in this embodiment. This wake-up circuit controls the start-up process. The wake-up circuit can be configured as follows: Figure 4 The circuit structure shown is such that when the system is turned on, pressing the encoder button S1 turns on the MOSFET Q1 and keeps it on, thus starting the system. The step-down chip U1 then converts the battery voltage to 3.3V to power the water pressure sensor, microcontroller, and electronic screen.
