Description

Technical Field

[0001] The invention relates to the technical field of flashlights, in particular to a color-adjustable flashlight capable of automatically adjusting focus. Background Art

[0002] A flashlight is a common lighting tool, which is mainly composed of a housing, a power source, a light source, a switch, etc. At present, the main technologies used in flashlights include light sources, batteries, reflectors, switches, etc.

[0003] The light source is one of the core components of a flashlight. Currently, common light sources include incandescent bulbs, xenon lamps, and LED lamps. Traditional flashlights use incandescent bulbs as light sources, which have the advantage of high brightness, but high power consumption, which affects battery life. Xenon lamps provide brighter light, but the power consumption is still high. LED lamps have become the mainstream light source for modern flashlights, with advantages including high brightness, low power consumption, long life, and vibration resistance.

[0004] The reflector is a component in a flashlight that controls the range of light divergence. Traditional flashlights use mirror reflectors, which can concentrate light into a stronger beam. Modern flashlights often use convex lens reflectors, which have an adjustable focal length and can adjust the focusing effect of light.

[0005] In the existing flashlight technology, a major defect is that the light color is single and the focal length cannot be adjusted electrically. Traditional flashlights usually only provide white light sources and cannot be switched to light sources of other colors. This limits the flexibility of the flashlight in different scenarios and cannot meet specific needs, such as red light for night observation and green light for hunting; in addition, traditional flashlights cannot adjust the focal length, that is, the focusing and diffusion of the light beam cannot be achieved. Flashlights usually use fixed focusing lenses or reflectors to control the shape and range of the light beam. Users cannot electrically adjust the focal length to meet the needs of different usage scenarios, such as long-distance lighting or close-range work. These defects limit the application range and flexibility of the flashlight. For this reason, a color-adjustable flashlight with automatic focusing is proposed. Summary of the invention

[0051] When the present invention is working: when it is necessary to adjust the color and focal length of the RGBYW lamp bead 1, the user can select the lamp bead that needs to be adjusted, and adjust the duty cycle to achieve the output of the flashlight color and the adjustment of the aperture size. The RGBYW lamp bead 1 is a lamp bead with 6 pins, wherein the common cathode pin of the RGBYW lamp bead 1 is grounded, and the remaining 5 pins are positive control pins of the five colors of RGBYW. The duty cycle output to the 5 pins of the lamp bead can be controlled to change the brightness of each color, and the mixing of each color completes the output of different colors of the flashlight. When performing a zoom operation, the focus motor 17 is started, and the focus motor 17 drives the focus screw 16 to rotate. The focus screw 16 rotates in the first shell connection block 18, driving the first shell connection block 18 to move up and down. The first shell connection block 18 drives the first shell body 6 to move, thereby driving the glass focusing lens 5 to move, and changing the distance from the glass focusing lens 5 to the RGBYW lamp bead 1, thereby completing the zoom. Figure 1 The software initialization flow chart of the present invention shows that when the user turns on the power to the MCU, the main control MCU will start working and initialize five buttons to the input mode; the output pin of the RGBYW lamp bead 1 is initialized to the PWM output mode, and the output duty cycle is set to 0; the automatic zoom control motor output is initialized to the PWM output mode, and the output duty cycle is set to 0; the temperature sensor pin is initialized to the ADC sampling input mode, and the cooling fan is initialized to the PWM output mode, and the output duty cycle is set to 0; the screen pin is initialized to the IIC mode, and an initialization command is sent to the screen, at which time the screen will be cleared and the initialization interface will be displayed; the Bluetooth module pin is initialized to the UART mode, and an initialization command is sent to the Bluetooth module, at which time the Bluetooth module will enter the standby state and wait for the main control MCU to send a connection start function; the RGBYW output duty cycle, strobe speed and other parameters saved in the FLASH at the last shutdown are read and the relevant variables are assigned values, thereby restoring the state before the last power failure, and the initialization configuration of the software part is successful at this point;

[0052] Figure 2 This is the software control flow chart of the present invention. After the MCU is initialized, the user can select the current mode as stand-alone mode or Bluetooth mode through the up, down, left, right, and confirm buttons and the screen;

[0053] Stand-alone mode: Users can use the up, down, left, right, and confirm buttons and the screen to select the output duty cycle of each color of the current flashlight, RGBYW, to change the color of the flashlight output. They can also select the automatic zoom function to adjust the focal length of the flashlight to change the size of the aperture, and save the current configuration by selecting the save selection box on the screen. The automatic heat dissipation function of the system will first collect the data of the current temperature sensor through the ADC and calculate the current temperature through the algorithm. According to the set PID algorithm and the current fan speed, the duty cycle of the fan's automatic output is adjusted to close the loop and adjust the fan speed. Repeated adjustments are made in this way to ensure that the internal temperature of the flashlight does not exceed the set safety value.

[0054] Bluetooth mode: When the user selects the Bluetooth mode, the main control MCU will send a connection command to the Bluetooth module, and the Bluetooth module will start working. Open the mobile phone APP and turn on the mobile phone Bluetooth, and you can search for the Bluetooth of this invention. After selecting the connection, the APP will display the current power of the flashlight, the output duty cycle of each color of RGBYW and the mixed color, the internal temperature of the flashlight, the speed of the 4 speed-adjustable cooling fans, and other information. The configuration of the flashlight can also be modified through the mobile phone APP, thereby completing the various functions of the flashlight stand-alone mode;

[0055] This function also has a multi-flashlight interconnection function. When this function is turned on, the Bluetooth module will switch to the Bluetooth Mesh networking working mode. In this working mode, the user also controls the flashlight through the mobile phone APP, but the flashlight in this mode will search whether there is another flashlight in this mode nearby. When a flashlight in this mode is found, the flashlight will forward the command to other flashlights to complete the interconnection function of multiple flashlights. This function is mainly used in an environment where people are trapped and in urgent need of rescue. Multiple flashlights can emit red light synchronously and strobe with the same frequency, making it easier for search and rescue personnel to find them;

[0056] Figure 3The hardware control flow chart of the present invention shows the connection mode between each hardware and MCU during the design process; the battery 13 and the charge and discharge module are the core of the power supply of each hardware of the present invention, mainly providing power for the MCU, the speed-adjustable cooling fan 4, the display screen 7, the Bluetooth module, the focusing motor 17, and the RGBYW lamp bead 1; the default output of the button is a low level, and when pressed, it is turned on to a high level and output to the MCU pin. There is a Hall sensor inside the speed-adjustable cooling fan 4. When the speed-adjustable cooling fan 4 rotates, the Hall sensor will output a square wave of the current speed to the MCU pin; the temperature sensor can detect the change of temperature by connecting to the input capture pin of the MCU. The temperature sensor will cause the change of its internal resistance according to the change of temperature. Each change can be converted by the ADC module of the MCU and converted into a corresponding digital quantity. In this way, the MCU can obtain the temperature value measured by the temperature sensor and further perform relevant processing and control. The screen is connected to the MCU through IIC to complete the control of the screen. The SCL and SDA pins of IIC need to be pulled up during the design process. The RGBYW colors need to be controlled by the MCU pins. By outputting PWM waves with different duty cycles, the colors output by each lamp bead can be changed. The lamp beads of each color will be mixed and become the color output by the flashlight. The focusing motor 17 and the speed-regulating cooling fan 4 are PWM outputs. During the design process, they can be adjusted according to the actual current required by the focusing motor 17 and the speed-regulating cooling fan 4.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
