Technology Field
[0001] The present disclosure relates to an electronic device and a method for controlling the same, and more specifically, to an electronic device and a method for controlling the same that detect when an object is introduced into a socket to which a light source is coupled and control the power supply to the socket. Background Technology
[0002] With technological advancements, electronic devices equipped with various optical output functions are being developed, such as lighting devices, display devices, portable communication devices, or projectors. These electronic devices may include a socket structure to which a light source is incorporated, and recently, there has been an increase in electronic devices equipped with multimedia output or smart functions in addition to lighting capabilities, utilizing power-efficient and eco-friendly LED bulbs.
[0003] Conventional light bulb sockets posed a risk of electric shock because parts of the socket's electrodes were exposed when the bulb was removed; consequently, electronic devices containing bulbs required special caution during handling. Furthermore, due to these safety issues, electronic devices including conventional bulb sockets had to obtain certification as lighting devices under US (Underwriter's Laboratories) or NEC (National Electrical Code) regulations, even if they featured multimedia output or smart functions. Therefore, electronic devices equipped with the function to detect the proper insertion of a bulb and control the power supply offer the advantage of reducing the risk of electric shock compared to lighting devices and enabling them to obtain certification as multimedia devices. Accordingly, there has been a technical demand for electronic devices capable of reliably cutting off power to the socket when the bulb is removed and detecting the proper insertion and detachment of the bulb. The problem to be solved
[0004] The present disclosure is designed to improve upon the aforementioned problem and relates to an electronic device and a method for controlling the same, which detects the coupling state of a socket and controls the power supply, comprising a sensor that detects when an object is inserted into a socket and a galvanometer that detects the intensity of the current flowing through the socket. means of solving the problem

The processor controls the switch for a preset galvanometer time when the insertion of an object into the socket is detected, and can control the switch to maintain the supply of current to the socket based on the value of the current flowing through the socket during the galvanometer time.
[0006] In this case, the processor can control the switch so that the current supply to the socket is maintained based on the current value measured after the first waiting time, which is the initial time of the galvanizing time.
[0007] Meanwhile, the processor may repeat a cycle multiple times in which the switch is turned on for a preset first time and the switch is turned off for a preset second time during the galvanizing time.
[0008] In this case, the processor can maintain the ON state of the switch based on the current value measured after a preset number of initial cycles among the plurality of cycles.
[0009] Meanwhile, the processor can maintain the ON state of the switch if the current value is between a first current value, which is a preset positive value, and a second current value, which is a preset negative value.
[0010] In this case, the processor can control the switch so that the supply of current to the socket is cut off if the current value is greater than or equal to the first current value or less than or equal to the second current value.
[0011] In this case, the processor may turn the switch on and off again for the galvanized current time after turning off the switch based on the current value.
[0012] Meanwhile, the sensor may include a light-emitting part that irradiates light into the socket, a light-receiving part that is spaced apart from the light-emitting part and recognizes the light, and a transmission part that detects the recognition state of the light by the light-receiving part and transmits it to the processor.
[0013] In this case, the sensor may be an infrared sensor in which the light-emitting part and the light-receiving part irradiate and recognize infrared rays.
[0014] Meanwhile, the sensor may include a button that protrudes into the socket and moves as it is pushed when an object is inserted, a spring that supports the button and provides elastic force, and an electrode that contacts and separates from the button based on the movement of the button and supplies or cuts off current to the socket.
[0015] In this case, the sensor may include a plurality of the buttons spaced apart and disposed inside the socket, and may include a plurality of the springs and electrodes corresponding to the plurality of buttons.
[0016] Meanwhile, the above galvanometer may include a galvanometer placed in the path through which the current flowing to the socket travels, an amplifier that amplifies the voltage of the galvanometer, and a comparator that receives the voltage of the amplifier, compares it with a preset voltage value, and provides it to the processor.
[0017] Additionally, a control method for an electronic device according to various embodiments of the present disclosure may include the steps of detecting whether an object is inserted into a socket, controlling a switch that controls the supply of current to the socket for a preset galvanizing time, checking the value of the current flowing through the socket during the galvanizing time, and controlling the switch to maintain the supply of current to the socket based on the value of the current.
[0018] In this case, the step of checking the current value flowing through the socket during the galvanizing time may include a step of waiting during a first waiting time, which is an initial time during the galvanizing time, and a step of checking the current value measured after the step of waiting during the first waiting time.
[0019] Meanwhile, the step of controlling the switch during the above-mentioned preset galvanizing time may repeat a cycle in which the switch is turned on for a preset first time and the switch is turned off for a preset second time multiple times.
[0020] In this case, the step of checking the current value flowing through the socket during the above galvanizing time can check the current value measured after an initial number of preset cycles among a plurality of the above cycles.
[0021] Meanwhile, the step of checking the current value flowing through the socket during the above galvanizing time may proceed to the step of maintaining the current supply to the socket if the current value is between a first current value, which is a preset positive value, and a second current value, which is a preset negative value.
[0022] In this case, the step of checking the current value flowing to the socket during the galvanizing time may include the step of controlling the switch to cut off the current supply to the socket if the current value is greater than or equal to the first current value or less than or equal to the second current value.
[0023] In this case, the step of cutting off the current supply to the socket may include the step of waiting for a preset second waiting time after turning off the switch.
[0024] Meanwhile, the step of controlling the switch to cut off the current supply to the socket may return to the step of controlling the switch for the galvanized time after turning off the switch. Brief explanation of the drawing

[0036] Hereinafter, the electronic device of the present disclosure will be described in detail with reference to FIGS. 1 to 8.
[0037] FIG. 1 is a perspective view illustrating the appearance of an electronic device (100) according to one embodiment of the present disclosure. Referring to FIG. 1, the electronic device (100) may include a head (103), a main body (105), a projection lens (110), a socket (150), or a cover (107).
[0038] The electronic device (100) can be a device of various forms. In particular, the electronic device (100) may be a projector device that projects an enlarged image onto a wall or screen, and the projector device may be an LCD projector or a DLP (digital light processing) projector using a DMD (digital micromirror device).
[0039] Additionally, the electronic device (100) may be a home or industrial display device, or a lighting device used in daily life, or a sound device including a sound module, or may be implemented as a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a wearable device, or a home appliance. Meanwhile, the electronic device (100) according to one embodiment of the present disclosure is not limited to the devices described above, and the electronic device (100) may be implemented as an electronic device (100) having two or more functions of the devices described above. For example, the electronic device (100) may be used as a display device, a lighting device, or a sound device by turning off the projector function and turning on the lighting function or speaker function according to the operation of the processor, and may be used as an AI speaker by including a microphone or a communication device.
[0040] The main body (105) is a housing that forms the exterior and can support or protect components of an electronic device (100) placed inside the main body (105) (e.g., a configuration shown in FIG. 2). The shape of the main body (105) may have a structure close to a cylinder as shown in FIG. 1. However, the shape of the main body (105) is not limited thereto, and according to various embodiments of the present disclosure, the main body (105) may be implemented in various geometric shapes such as a column, a cone, or a sphere having a polygonal cross-section.
[0041] The size of the main body (105) may be such that a user can hold or move it with one hand, may be implemented in a super-compact size for easy portability, and may be implemented in a size that can be mounted on a table or combined with a lighting device.
[0042] The material of the main body (105) may be made of a matte metal or synthetic resin so that the user's fingerprints or dust do not adhere to it, or, the exterior of the main body (105) may be made of a smooth glossy finish.
[0043] A friction area may be formed in a part of the exterior of the main body (105) so that a user can grip and move it. Alternatively, the main body (105) may be provided with a folded gripping part or support (108, see FIG. 3) that a user can grip in at least a part of the area.
[0044] A projection lens (110) is formed on one side of the main body (105) to project light that has passed through a lens array out of the main body (105). In various embodiments, the projection lens (110) may be an optical lens with a low-dispersion coating to reduce chromatic aberration. The projection lens (110) may be a convex lens or a condensing lens, and in one embodiment, the projection lens (110) may adjust the focus by adjusting the positions of a plurality of sub-lenses.
[0045] The head (103) is provided to be coupled to one side of the main body (105) to support and protect the projection lens (110). The head (103) can be coupled to the main body (105) so as to be swivelable within a preset angle range relative to one side of the main body (105).
[0046] The head (103) can be swiveled automatically or manually by a user or processor to freely adjust the projection angle of the projection lens (110). Alternatively, although not shown in the drawing, the head (103) may be coupled to the main body (105) and may include a neck extending from the main body (105), so that the head (103) may be tilted or tilted to adjust the projection angle of the projection lens (110).
[0047] The electronic device (100) can project light or an image to a desired location by adjusting the direction of the head (103) and the emission angle of the projection lens (110) while the position and angle of the main body (105) are fixed. Additionally, the head (103) may include a handle that can be grasped after being rotated in a desired direction by the user.
[0048] A plurality of openings may be formed on the outer surface of the main body (105). Audio output from the audio output unit may be output to the outside of the main body (105) of the electronic device (100) through the plurality of openings. The audio output unit may include a speaker, and the speaker may be used for general purposes such as multimedia playback, recording playback, voice output, etc.
[0049] According to one embodiment of the present disclosure, a heat dissipation fan (not shown) may be provided inside the main body (105), and when the heat dissipation fan (not shown) is driven, air or heat inside the main body (105) can be discharged through a plurality of openings. Therefore, the electronic device (100) can discharge heat generated by the operation of the electronic device (100) to the outside and prevent the electronic device (100) from overheating.
[0050] The socket (150) can connect the electronic device (100) to an external device to transmit and receive electrical signals or receive power from an external source. According to one embodiment of the present disclosure, the socket (150) can be physically connected to an external device. In this case, the socket (150) may include an input / output interface and may communicate with the external device via wired or wireless means or receive power. For example, the socket (150) may include an HDMI connection terminal, a USB connection terminal, an SD card receiving slot, an audio connection terminal, or a power outlet, or may include a Bluetooth, Wi-Fi, or wireless charging connection module that is wirelessly connected to an external device.
[0051] Additionally, the socket (150) may have a socket structure connected to an external lighting device and may receive power by being connected to the socket receiving groove of the external lighting device. The size and specifications of the socket structure (150) can be implemented in various ways considering the receiving structure of the external device that can be combined. For example, according to the international standard E26, the diameter of the joint portion of the socket (150) may be implemented as 26 mm, in which case the electronic device (100) can be combined with an external lighting device such as a stand by replacing a conventionally used light bulb. Meanwhile, when connected to an existing socket located on the ceiling, the electronic device (100) has a structure that projects from top to bottom, and if the electronic device (100) does not rotate due to the socket connection, the screen also cannot rotate. Accordingly, even when power is supplied through a socket connection, the electronic device (100) can rotate. The electronic device (100) is socket-connected to a stand on the ceiling, and the head (103) swivels on one side of the main body (105) to adjust the projection angle, thereby allowing the screen to be projected to a desired position or the screen to be rotated.
[0052] The socket (150) may include a coupling sensor, and the coupling sensor may sense whether the socket (150) and an external device are coupled, the coupling state, or the coupling target and transmit this to a processor, and the processor may control the operation of the electronic device (100) based on the received detection value. Specific operations of the processor controlling the operation of the electronic device (100) based on the detection result of the coupling sensor will be described in detail later with reference to FIGS. 4a to 8.
[0053] The cover (107) can be attached to and detached from the main body (105) and can protect the socket (150) so that the socket (150) is not always exposed to the outside. The shape of the cover (107) may have a shape that is continuous with the main body (105) as shown in FIG. 1, or it may be implemented to correspond to the shape of the socket (150). The cover (107) can support an electronic device (100), and the electronic device (100) can be attached to the cover (107) and used by being attached to or mounted on an external stand.
[0054] In various embodiments of the electronic device (100), a battery may be provided inside the cover (107). The battery may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.
[0055] Although not illustrated in the drawings, the electronic device (100) may include a camera module, and the camera module may capture still images and video. According to one embodiment, the camera module may include one or more lenses, an image sensor, an image signal processor, or a flash.
[0056] Although not shown in the drawing, the electronic device (100) may include a protective case (not shown) to protect the electronic device (100) and to allow for easy transport, or may include a stand (not shown) that supports or fixes the main body (105), or a bracket (not shown) that can be attached to a wall or partition.
[0057] Additionally, the electronic device (100) can be connected to various external devices using a socket structure to provide various functions. In one embodiment, the electronic device (100) can be connected to an external camera device using a socket structure. The electronic device (100) can provide images stored in the connected camera device or images currently being captured using a projection unit (210). In another embodiment, the electronic device (100) can be connected to a battery module using a socket structure to receive power. Meanwhile, although the electronic device (100) can be connected to an external device using a socket structure, this is merely one embodiment, and it can be connected to an external device using another interface (e.g., USB, etc.).
[0058] FIG. 2 is a block diagram illustrating the configuration of an electronic device according to one embodiment of the present disclosure. As shown in FIG. 2, the electronic device (100) may include a projection unit (210), a memory (220), a user interface (230), an input / output interface (240), an audio output unit (250), a power supply unit (260), a processor (270), and a sensor unit (280). Meanwhile, the configuration shown in FIG. 2 is merely one embodiment, and some components may be omitted, and new components may be added.
[0059] The projection unit (210) is configured to project an image outward. According to one embodiment of the present disclosure, the projection unit (210) can be implemented using various projection methods (e.g., cathode-ray tube (CRT) method, liquid crystal display (LCD) method, digital light processing (DLP) method, laser method, etc.). For example, the CRT method is basically the same principle as a CRT monitor. The CRT method magnifies the image using a lens in front of the cathode-ray tube (CRT) to display an image on a screen. Depending on the number of cathode-ray tubes, it is divided into a single-tube type and a three-tube type, and in the case of the three-tube type, the red, green, and blue cathode-ray tubes can be implemented separately.
[0060] As another example, the LCD method displays an image by transmitting light from a light source through a liquid crystal. LCD methods are divided into single-panel and three-panel types. In the case of the three-panel type, light from a light source is separated into Red, Green, and Blue by a dichroic mirror (a mirror that reflects only specific colors of light and allows the rest to pass through), then passes through the liquid crystal, and finally converges back into one place.
[0061] As another example, the DLP method is a technique that displays images using a DMD (Digital Micromirror Device) chip. The projection section of the DLP method may include a light source, a color wheel, a DMD chip, and a projection lens. Light emitted from the light source can acquire color as it passes through a rotating color wheel. The light passing through the color wheel is input into the DMD chip. The DMD chip contains numerous micro-mirrors and reflects the light input into it. The projection lens performs the function of magnifying the light reflected from the DMD chip to the size of the image.
[0062] As another example, the laser method includes DPSS (Diode Pumped Solid State) lasers and galvanometers. Lasers that output various colors utilize a laser formed by installing three DPSS lasers for each RGB color and superimposing their optical axes using special mirrors. The galvanometer includes mirrors and high-output motors to move the mirrors at high speeds. For example, a galvanometer can rotate the mirror at a maximum speed of 40 KHz / sec. The galvanometer is mounted according to the scanning direction; since projectors generally perform planar scanning, the galvanometer can also be positioned along the x and y axes.
[0063] The projection unit (210) can output images with a 4:3 aspect ratio, a 5:4 aspect ratio, or a 16:9 wide aspect ratio depending on the use of the electronic device (100) or the user's settings, and can output images with various resolutions such as WVGA (854*480), SVGA (800*600), XGA (1024*768), WXGA (1280*720), WXGA (1280*800), SXGA (1280*1024), UXGA (1600*1200), and Full HD (1920*1080) depending on the aspect ratio.
[0064] Meanwhile, the projection unit (210) can perform various functions to adjust the output image under the control of the processor (270). For example, the projection unit (210) can perform functions such as zoom, keystone, quick corner (4-corner) keystone, and lens shift.
[0065] Specifically, the projection unit (210) can enlarge or reduce the image depending on the distance from the screen (projection distance). That is, a zoom function can be performed depending on the distance from the screen. At this time, the zoom function may include a hardware method that adjusts the screen size by moving a lens and a software method that adjusts the screen size by cropping the image. Meanwhile, when the zoom function is performed, the focus of the image needs to be adjusted. For example, the focus adjustment method includes a manual focus method and an electric method. A manual focus method refers to a method of manually adjusting the focus, and an electric method refers to a method in which the projector automatically adjusts the focus using a motor built into it when the zoom function is performed. When performing the zoom function, the projection unit (210) may provide a digital zoom function through software and may provide an optical zoom function that performs the zoom function by moving the lens through a driving unit.
[0066] Additionally, the projection unit (210) can perform a keystone function. If the height is not correct for front projection, the screen may be distorted upward or downward. The keystone function refers to a function that corrects the distorted screen. For example, if distortion occurs in the left-right direction of the screen, it can be corrected using horizontal keystone, and if distortion occurs in the up-down direction, it can be corrected using vertical keystone. The quick corner (4-corner) keystone function is a function that corrects the screen when the central area of the screen is normal but the corner areas are unbalanced. The lens shift function is a function that moves the screen as is when the screen is off the screen.
[0067] Meanwhile, the projection unit (210) can automatically provide zoom / keystone / focus functions by analyzing the surrounding environment and projection environment without user input. Specifically, the projection unit (210) can automatically provide zoom / keystone / focus functions based on the distance between the electronic device (100) and the screen detected through sensors (depth camera, distance sensor, infrared sensor, illuminance sensor, etc.), information about the space where the electronic device (100) is currently located, and information about the amount of ambient light.
[0068] Additionally, the projection unit (210) can provide a lighting function using a light source. In particular, the projection unit (210) can provide a lighting function by outputting a light source using an LED. According to one embodiment, the projection unit (210) may include a single LED, and according to another embodiment, the electronic device may include a plurality of LEDs. Meanwhile, the projection unit (210) may output a light source using a surface-emitting LED according to an implementation example. Here, the surface-emitting LED may refer to an LED having a structure in which an optical sheet is placed on the upper side of the LED so that the light source is evenly distributed and output. Specifically, when a light source is output through the LED, the light source can be evenly distributed through the optical sheet, and the light source distributed through the optical sheet can be incident on the display panel.
[0069] Meanwhile, the projection unit (210) can provide a dimming function to the user for adjusting the intensity of the light source. Specifically, when user input for adjusting the intensity of the light source is received from the user through the user interface (240) (e.g., a touch display button or a dial), the projection unit (210) can control the LED to output the intensity of the light source corresponding to the received user input.
[0070] Additionally, the projection unit (210) can provide a dimming function based on content analyzed by the processor (270) without user input. Specifically, the projection unit (210) can control an LED to output the intensity of a light source based on information about the currently provided content (e.g., content type, content brightness, etc.).
[0071] Meanwhile, the projection unit (210) can control the color temperature under the control of the processor (270). Here, the processor (270) can control the color temperature based on the content. Specifically, when the content is identified as being output, the processor (270) can obtain frame-by-frame color information of the content determined to be output. Then, the processor (270) can control the color temperature based on the obtained frame-by-frame color information. Here, the processor (270) can obtain at least one main color of the frame based on the frame-by-frame color information. Then, the processor (270) can adjust the color temperature based on at least one obtained main color. For example, the color temperature that the processor (270) can adjust can be classified as a warm type or a cold type.

In one embodiment, a head (103) including a light-emitting structure (not shown) and a projection lens (110) may be coupled to the upper part of the light source (40), but is not limited thereto and may be coupled with a light-emitting structure of various types and shapes.
[0132] The socket (150) can be coupled to the coupling part (50) of the light source (40), can supply power to the light source (40), and can transmit an electrical signal. The coupling structure of the socket (150) and the coupling part (50) of the light source (40) can be implemented in various ways, and the socket (150) can have a socket (150) structure of various types such as E40, E27, E26, E14, GU, B22, BX, BA, EP, EX, GY, GX, GR, GZ, G type so as to correspond to existing lighting devices.
[0133] The coupling portion (50) of the light source (40) illustrated in FIG. 4a is merely an exemplary coupling structure of the light source (40) and is not limited thereto in actual implementation, and the electronic device (100) of the present disclosure may have a socket (150) structure corresponding to various shapes and structures of the light source (40).
[0134] Since the socket (150) can be connected to or separated from the connecting part (50) of the light source (40), if other materials, such as a light source that does not fit the specifications of the socket (150), an external electronic product, a metal material, or a part of the user's body, are introduced into the socket (150) while the connecting part (50) of the light source (40) is separated, there is a risk of electric shock through the electrodes inside the socket (150).
[0135] Referring to FIG. 4b, the positions of the socket (150) and the light source (40) can be implemented in the opposite way to the structure of FIG. 4a. Specifically, the light source (40) is included in the projection part (210) as a component of the electronic device (100) and is positioned on the main body (105) side, and the socket (150) can be positioned so as to be selectively coupled with the coupling part (50) of the light source (40).
[0136] That is, the electronic device (100) of FIG. 4b may have a coupling structure in which the male and female parts are reversed compared to the electronic device (100) shown in FIG. 4a. The electronic devices (100) of FIG. 4a and 4b may have the same specifications and sizes as each other, except that only the positions of the socket (150) and the light source (40) are reversed.
[0137] The electronic device (100) may include a connecting part (109) that is detachable from the main body (105). The connecting part (109) may have a cylindrical shape, be formed of the same material as the main body (105), and have a cross-section of the same size. Accordingly, when the connecting part (109) is coupled to the main body (105), the main body (105) and the connecting part (109) may have a cylindrical shape as a single unit. The connecting part (109) may be coupled to the main body (105) by a screw coupling method, a key-groove coupling method, a hook coupling method, etc., but the coupling method is not limited thereto.
[0138] The light source (40) may be positioned to protrude toward the socket (150) from one side of the connection part (109). Accordingly, when power is to be supplied to the light source (40), the user may attach the connection part (109) to the main body (105) and connect the coupling part (50) of the light source (40) positioned on the connection part (109) to the socket (150).
[0139] The socket (150) is connected to a wire (W) to receive AC power from the outside through the wire (W) and can transmit it to the coupling part (50) of the light source (40). Accordingly, the light source (40) can receive power or an electrical signal from the socket (150) and emit light.
[0140] Hereinafter, with reference to FIGS. 5a to 8, the structure and operation of an electronic device (100) and a control method according to one embodiment of the present disclosure, which detect whether the coupling part (50) of a light source (40) is normally coupled to a socket (150) and control the power supply, will be described in detail.
[0141] FIGS. 5a to 5c are drawings illustrating the coupling process of a socket (150) of an electronic device (100) according to one embodiment of the present disclosure. Specifically, FIGS. 5a to 5c are drawings schematically illustrating the cross-sectional structure and circuit diagram of a part of the electronic device (100) based on the line I-I' of FIG. 4a.
[0142] Referring to FIGS. 5a to 5c, an electronic device (100) of one embodiment of the present disclosure may include a first sensor (160), a second sensor (170), and a galvanometer (180).
[0143] FIGS. 5a to 5c illustrate a structure in which the coupling part (50) of the light source (40) is coupled to the socket (150), but in actual implementation, it is not limited to this, and a light source that does not meet the specifications, an external electronic product, a metal material, or a part of the user's body may be inserted into the socket (150), and hereinafter, such external structures inserted into the socket (150) are collectively referred to as 'objects'.
[0144] Additionally, the circuit and structural drawings of FIGS. 5a to 5c are exemplary structures for explaining the structure of an electronic device (100) of one embodiment of the present disclosure, and are not limited thereto in actual implementation, but can be modified in various ways within a range obvious to those skilled in the art so as to implement the same or similar operation.
[0145] An electronic device (100) of one embodiment may include a Micro Controller Unit (hereinafter referred to as 'MCU') (190) that controls the power delivery structure of a socket (150). The MCU (190) may be the processor (270) described above, or may be a controller unit that is a component of the processor (270) for controlling the power of the socket (150).
[0146] In one embodiment of the present disclosure, the MCU (190) can perform a control operation to maintain or block power delivery to the socket (150) based on the result received from the galvanometer (180). In detail, the MCU (190) and some components of the galvanometer (180) described below can check whether the current flowing to the socket (150) exceeds a safe range and control the switch (181) based on this, and such components used for controlling the switch (181) may be referred to as a switch control unit (185).
[0147] The MCU (190) can receive an applied voltage (Vcc) from the power supply unit (260), and the MCU (190) can supply the applied voltage (Vcc) to the AC / DC converter and the second sensor (170). The AC / DC converter converts the applied voltage (Vcc) into a DC-AC form and can supply power to the socket (150).
[0148] The electronic device (100) may include sensors (160, 170) capable of detecting whether an external object, such as the coupling part (50) of the light source (40), is introduced into the socket (150) and providing the detection result to the processor (270). Although FIGS. 5a to 5c sequentially illustrate the process of the coupling part (50) of the light source (40) being introduced into the socket (150), in actual implementation, an object other than the coupling part (50) of the light source (40) may be introduced, and the power supply can be cut off through the process of detecting the other object using the sensors (160, 170) and the galvanometer (180).
[0149] The socket (150) may have a shape corresponding to the coupling part (50) of the light source (40). For example, the coupling part (50) may have a structure of a male screw or a bolt including a screw thread (53), and the socket (150) may have a structure of a female screw having a receiving groove (153) that receives the screw thread (53) of the coupling part (50). In this case, the coupling part (50) may rotate to be inserted into the socket (150) and fixed.
[0150] The socket (150) may include a socket housing (151) made of an insulator. The socket housing (151) may accommodate and secure a portion of the first sensor (160) or the second sensor (170). The socket housing (151) may have a first electrode (167) and a second electrode (168) embedded therein to supply power to an object inside the socket (150), and the socket housing (151) may support and secure the coupling portion (50), the first electrode (167), and the second electrode (168).
[0151] The sensor (160, 170) may include one of the first sensor (160) and the second sensor (170), or may include both the first sensor (160) and the second sensor (170). The first sensor (160) and the second sensor (170) may each detect whether an object is being inserted into the socket (150) in a respective manner and provide the detection result to the processor (270).
[0152] The first sensor (160) may include a button (161, 162) that protrudes into the socket (150) and moves outward when an object is inserted, and a spring (163, 164) that supports the button (161, 162) and provides elastic force. One end of the button (161, 162) may be formed in the receiving groove (153) of the socket (150), and the other end may be positioned to contact the spring (163, 164).
[0153] The buttons (161, 162) are pushed outward from the socket (150) when an object is inserted into the socket (150), and can move inward into the socket (150) by receiving elastic force from the springs (163, 164) when an object is separated from the socket (150).
[0154] The buttons (161, 162) may include a conductor (165, 166). The conductor (165, 166) is fixed to the buttons (161, 162) and can move and be fixed together with the buttons (161, 162).
[0155] The first sensor (160) may include a first button (161) and a second button (162) spaced apart from each other inside the socket (150). The first sensor (160) may include a first spring (163) and a second spring (164) corresponding to each of the first button (161) and the second button (162), and each of the first button (161) and the second button (162) may include a first conductor part (165) and a second conductor part (166).
[0156] The first electrode (167) may come into contact with or be separated from the first conductor portion (165) of the first button (161) based on the movement of the first button (161), and the second electrode (168) may come into contact with or be separated from the second conductor portion (166) of the second button (162) based on the movement of the second button (162). Therefore, the first electrode (167) and the second electrode (168) can supply or cut off current to the socket (150) by the first sensor (160).
[0157] Referring to FIGS. 5a and 5b, the process of the first button (161) being pushed and moved by the coupling part (50) can be observed. When at least a portion of the coupling part (50) is inserted into the socket (150), the coupling part (50) can push and move the first button (161), and the first conductor part (165) of the first button (161) moves to come into contact with or electrically connect with the first electrode (167), so that the first electrode (167) can provide alternating voltage to the socket (150).
[0158] As illustrated in FIG. 5b, if the coupling portion (50) moves only to the middle position of the socket (150), the first button (161) may be pushed and moved, but the second button (162) may not move. Since the second electrode (168) is separated from the second conductor portion (166) of the second button (162), the socket (150) may not receive power normally.
[0159] If an object other than the coupling part (50), such as a coupling part of a light source having different specifications, a conductive material, or the user's body, is inserted into the socket (150), the socket (150) cannot supply power unless both the first button (161) and the second button (162) are pushed and moved. For example, if the user presses only one button (161, 162), the socket (150) does not receive power, so the electronic device (100) can prevent the risk of the user being electrocuted.
[0160] Referring to FIGS. 5b and 5c, the process of the second button (162) being pushed and moved by the coupling part (50) can be observed. When the coupling part (50) is pushed further into the socket (150), the coupling part (50) can push and move the second button (162). The second conductor part (166) of the second button (162) can move and come into contact with or be electrically connected to the second electrode (168), and the first electrode (167) and the second electrode (168) can provide alternating voltage to the socket (150).
[0161] That is, the first sensor (160) may have a structure in which the first button (161) and the second button (162) are pressed when the coupling part (50) of a light source (40) of suitable specifications is inserted into the socket (150), but at least one of the first button (161) or the second button (162) is not pressed when another object is inserted, and through this, the first sensor (160) can detect the insertion of a suitable object into the socket (150).
[0162] The first sensor (160) can maintain or cut off power supply to the socket (150) based on an object being introduced into the socket (150), and can prevent leakage current of the electronic device (100) by cutting off the power. In addition, the first sensor (160) can mechanically supply and cut off power to the socket (150) without separate signal transmission from the processor (270) or MCU (190).
[0163] The second sensor (170) may be a light sensor comprising a light-emitting part (171) that irradiates light (L) into the socket (150), a light-receiving part (172) that is spaced apart from the light-emitting part (171) and receives the light (L), and a transmission part (173) that detects the recognition state of the light (L) of the light-receiving part (172) and transmits it to the MCU (190). In one embodiment, the light-emitting part (171) and the light-receiving part (172) may irradiate and recognize infrared light (L), and the second sensor (170) may be an infrared sensor.
[0164] At least one of the light-emitting part (171) and the light-receiving part (172) may be positioned adjacent to the end of the coupling part (50) when the coupling part (50) is completed to the socket (150). The light-emitting part (171) may irradiate light (L) at predetermined intervals or may continuously irradiate light (L). When the coupling part (50) is completed to the socket (150), the coupling part (50) may be positioned in a space separated from the light-emitting part (171) and the light-receiving part (172).
[0165] The transmission unit (173) can transmit the state in which the light receiving unit (172) recognizes light (L) to the first input unit (IN1) of the MCU (190). For example, the state in which the light receiving unit (172) recognizes light (L) can be a High state or S1 state (see FIG. 6a), and the state in which the light receiving unit (172) does not recognize light (L) or the amount of light recognized is reduced to a certain level or lower can be a Low state or S2 state (see FIG. 6a).
[0166] The light receiving unit (172) can continuously recognize light (L) from the light emitting unit (171), and as shown in FIG. 5a and FIG. 5b, if there is no obstacle between the light receiving unit (172) and the light emitting unit (171), the transmission unit (173) can maintain the S1 state.
[0167] As illustrated in FIG. 5c, when the coupling part (50) is coupled into the socket (150) or when an external object enters and blocks the space between the light receiving part (172) and the light emitting part (171), the light (L) irradiated from the light emitting part (171) is blocked by the obstacle and the light (L) reaching the light receiving part (172) may be reduced.
[0168] The light receiving unit (172) can detect a change in light (L) and provide the detection result to the transmission unit (173). The S1 and S2 states of the transmission unit (173) are transmitted to the MCU (190) through the first input unit (IN1), and the MCU (190) can control the operation of the switch (181) based on this.
[0169] The switch (181) can control the supply of current to the socket (150). For example, the switch (181) can be turned on to supply current to the socket (150) or turned off to cut off the current to the socket (150).
[0170] The switch (181) may be placed on a path leading from the AC / DC converter to the first electrode (167) and the second electrode (168) of the socket (150). The switch (181) may be controlled by an MCU (190), and the MCU (190) may control the switch (181) based on a sensor and a galvanometer (180).
[0171] Due to various factors such as aging of the electronic device (100), external impact, overheating, or damage, there is a possibility that the first sensor (160) or the second sensor (170) may misidentify that the appropriate coupling part (50) is not inserted into the socket (150). The electronic device (100) of one embodiment of the present disclosure can prevent the risk of electric shock of the electronic device (100) in the event that a malfunction or error occurs in either one of the sensors, including the first sensor (160) and the second sensor (170).
[0172] For example, even if an unsuitable external object is introduced into the socket (150) and the first button (161) and second button (162) of the first sensor (160) are pushed and the first electrode (167) and second electrode (168) are connected to the AC / DC converter, if the second sensor (170) maintains the S1 state, the MCU (190) can keep the switch (181) in the off state and cut off the power supply to the socket (150). Additionally, even if an unsuitable external object is introduced into the socket (150) and the second sensor (170) switches to the S2 state, the first sensor (160) can cut off the power supply to the socket (150) unless both the first button (161) and the second button (162) are pushed.
[0173] The electronic device (100) of the present disclosure can have a double safety device function that prevents electric shock caused by an object entering the socket (150) because, even if one of the first sensor (160) and the second sensor (170) malfunctions, the other can cut off the current supply to the socket (150). Furthermore, the electronic device (100) of the present disclosure can have a triple safety function through a galvanometer (180) to be described later.
[0174] The galvanometer (180) is a device for detecting current flowing into the socket (150) and may include a galvanometer (183) placed in the path where the current flowing into the socket (150) travels, an amplifier (184) that measures and amplifies the voltage of the galvanometer (183), and a comparator (186, 188) that receives the voltage of the amplifier (184), compares it with a preset voltage value, and provides it to the MCU (190).
[0175] In one embodiment, the galvanometer (183) may be connected in series with the switch (181), and when the switch (181) is turned on and voltage is applied to the socket (150), voltage, hereinafter galvanometer voltage, may also be applied to the galvanometer (183). The galvanometer (183) is a resistor for detecting normal coupling of the socket (150), and the resistance value of the galvanometer (183) may be set very low to minimize power loss when the socket (150) receives normal current.
[0176] The galvanometer (180) can include an amplifier (184) to amplify the voltage value of the galvanometer (183). When a galvanometer voltage is applied to both ends of the galvanometer (183), the amplifier (184) can amplify the galvanometer voltage of the galvanometer (183) and transmit it to the comparator (186, 188).
[0177] The comparator (186, 188) may include a first comparator (186) and a second comparator (188). The first comparator (186) can compare the amplified galvanic voltage with a preset first voltage value (V1, see FIG. 6a) when the galvanic voltage is a forward voltage, and the second comparator (188) can compare the amplified galvanic voltage with a preset second voltage value (V2, see FIG. 6a) when the galvanic voltage is a reverse voltage.
[0178] In detail, the first comparator (186) is connected to a first voltage source (187) having a first voltage value (V1) and can transmit a High or Low output to one diode of the second input section (IN2) depending on whether the amplified galvanic voltage is greater than the first voltage value (V1). The second comparator (188) is connected to a second voltage source (189) having a second voltage value (V2) and can transmit a High or Low output to another diode of the second input section (IN2) depending on whether the amplified galvanic voltage is less than the second voltage value (V2).
[0179] The outputs of the first comparator (186) and the second comparator (188) can each be transmitted to the second input section (IN2) of the MCU (190) through a diode. The MCU (190) can predict the current value flowing to the socket (150) based on the input result of the second input section (IN2), and can control the switch (181) through the first output section (OUT1) based on this.
[0180] FIG. 6a is a graph illustrating a control method of an electronic device (100) according to one embodiment of the present disclosure, and FIG. 6b is a graph illustrating a control method of an electronic device (100) according to one embodiment of the present disclosure.
[0181] Below, the operation of the sensor (160, 170), switch (181), and galvanometer (180) will be described in detail with reference to FIGS. 6a and 6b.
[0182] S1 of the sensor (160, 170) may be a state where an object is not inserted into the socket (150) or is not fully inserted, and S2 may be a state where an object is fully inserted into the socket (150) and combined. For example, if the light receiving part (172) of the second sensor (170) does not recognize light (L) or the amount of light decreases, the second sensor (170) may detect the insertion of an object and change from the S1 state to the S2 state.
[0183] Point A may be the state of FIG. 5b where an object is inserted into the socket (150) up to the midpoint, or a state where one of the first sensor (160) and the second sensor (170) recognizes the insertion of the object. Point B may be the state of FIG. 5c where the object is fully inserted into and coupled to the socket (150), or a state where both the first sensor (160) and the second sensor (170) recognize the insertion of the object.
[0184] When time B is reached, the MCU (190) can control the switch (181) for a preset galvanizing time when the entry of an object into the socket (150) is detected. For example, the MCU (190) can control the switch (181) so that the ON state and OFF state of the switch (181) are repeated sequentially for a preset galvanizing time when the entry of an object into the socket (150) is detected.
[0185] In detail, the MCU (190) may repeat a cycle multiple times in which the switch (181) is turned on for a preset first time (t1) and the switch (181) is turned off for a preset second time (t2) during the galvanizing time. The first time (t1) and the second time (t2) may be short time intervals; for example, the first time (t1) may be a time within the range of tens of microseconds, and the second time (t2) may be a time within the range of hundreds of microseconds. The electronic device (100) of the present disclosure can reduce the risk of electric shock even if the object introduced into the socket (150) is an unsuitable object through a rapid galvanizing process.
[0186] When the switch (181) is repeatedly turned on and off, a galvanic voltage can be applied across the ends of the galvanic resistor (183), and the galvanic device (180) can receive the output value of the galvanic voltage that has passed through the amplifier (184). The galvanic device (150) can check whether the output value of the amplifier (184) is within a preset range, and based on this, can transmit data regarding the current value flowing through the socket (150) to the MCU (190).
[0187] If the output value of the MCU (190) is measured to be greater than the first voltage value (V1) or less than the second voltage value (V2), the MCU (190) can confirm that a voltage greater than the expected value has been applied to the galvanometer (183), and based on this, can determine that the object introduced into the socket (150) is an unsuitable object and turn off the switch (181). The first voltage value (V1) and the second voltage value (V2) can be set in various ways depending on the type of electronic device (100), the type and specifications of the light source (40), the amplification multiplier of the amplifier (184), etc., and, for example, may be around 10 V.
[0188] In one embodiment, the MCU (190) may ignore the output value during the first waiting time (C), which is the initial time during the galvanizing time, and the subsequent time may be the galvanizing time (D). Then, the ON state of the switch (181) may be determined based on the output value measured during the galvanizing time (D). If the light source (40) contains a capacitor with a large capacity of the SMPS input terminal, an inrush current may occur initially, so the initial output value may be ignored.
[0189] The first waiting time (C) may be set to a preset time range, or it may be the initial cycle of a preset number of cycles in which the switch (181) is turned on and off. For example, in FIGS. 6a to 7, the first waiting time is set to five initial cycles, and this can be set to various values depending on the operating environment of the electronic device (100).
[0190] After the first waiting time (C), the MCU (190) can determine whether the output value (Output) is stable by repeatedly turning the switch (181) on and off for a preset galvanizing time (D). The galvanizing time (D) can be set to a preset time range, or it can be a later cycle of a preset number of cycles in which the switch (181) is turned on and off.
[0191] Referring to FIG. 6a, it can be seen that when the output value (Output) is a forward voltage, the output value (Output) is initially greater than the first voltage value (V1) due to the inrush current, but stabilizes after the first waiting time (C) and the galvanizing time (D) to have a value within the first voltage value (V1). The MCU (190) can control the switch (181) so that the current supply to the socket (150) is maintained after the galvanizing time (D) if the output value (Output) during the first waiting time (C) and the galvanizing time (D) is within the first voltage value (V1) and the second voltage value (V2).
[0192] Referring to FIG. 6b, it can be seen that when the output value (Output) is reverse voltage, the output value (Output) is initially smaller than the second voltage value (V2) due to the inrush current, but stabilizes after the first waiting time (C) and the galvanizing time (D) to have a value within the second voltage value (V2). The MCU (190) can control the switch (181) so that the current supply to the socket (150) is maintained after the galvanizing time (D) if the output value (Output) during the first waiting time (C) and the galvanizing time (D) is within the first voltage value (V1) and the second voltage value (V2).
[0193] The MCU (190) can measure the range of current values flowing to the socket (150) through the data of the galvanometer (180), measure whether the current values flowing to the socket (150) are within the range of a first current value (V1), which is a preset positive value, and a second current value (V2), which is a preset negative value, and determine whether to maintain the ON state of the switch (181) based on this.
[0194] FIG. 7 is a graph illustrating a control method of an electronic device (100) according to one embodiment of the present disclosure.
[0195] Specifically, FIG. 7 is a graph illustrating the simulated operation of the electronic device (100) when an unsuitable object is introduced into the socket (150).
[0196] The galvanometer (180) can detect a point (d) where the output value (Output) exceeds the first voltage value (V1) during the first galvanometer time (D1) after the first waiting time (C) and transmit it to the MCU (190). If the output value (Output) is greater than or exceeds the first voltage value (V1), the MCU (190) can confirm that the current flowing to the socket (150) is in an overcurrent state because the current exceeds the first current value, and can turn off the switch (181) to cut off the current flowing to the socket (150).
[0197] In one embodiment, the MCU (190) can maintain the off state of the switch (181) for a preset second waiting time (t3) when it detects an overcurrent condition as shown in FIG. 7. After turning the switch (181) off, the MCU (190) can turn the switch (181) on and off again to proceed with the galvanizing time (D2).
[0198] The MCU (190) can repeat turning the switch (181) on and off again after the second waiting time (t3). The MCU (190) can conduct galvanizing again during the second galvanizing time (D2) after the first waiting time (C). Referring to FIG. 7, a point (d) where the output value (Output) exceeds the first voltage value (V1) is detected relatively early during the second galvanizing time (D2), and the MCU (190) can immediately turn off the switch (181) to cut off the current flowing to the socket (150).
[0199] The MCU (190) may have a second waiting time (t3) after the second galvanizing time (D2) and may repeat turning the switch (181) on and off again. The MCU (190) may conduct galvanizing again during the third galvanizing time (D3) after the first waiting time (C). Referring to FIG. 7, during the third galvanizing time (D3), a point (d) where the output value is less than or equal to the second voltage value (V2) can be detected, and the MCU (190) can check this and immediately turn off the switch (181) to cut off the current flowing to the socket (150).
[0200] The MCU (190) can set different lengths for the first waiting time (C), the second waiting time (t3), and the galvanizing time (D) after the second galvanizing time (D2), and can stop galvanizing and temporarily cut off power supply to the socket (150) when the galvanizing time of the preset order is exceeded. Additionally, if multiple galvanizing times (D) are repeated more than a preset number of times, the MCU (190) transmits this to the processor (270), and the processor (270) can notify the user of the abnormal combination.
[0201] If the current applied to the socket (150) exceeds a preset safety range due to an artificial cause, for example, a malfunction of the first sensor (160) or the second sensor (170) or the ingress of an unsuitable object, the processor (270) to the MCU (190) turns off the switch (181) and performs a safety operation to prevent electric shock or safety accidents, and if this phenomenon continues to occur in multiple current stages, additional safety operations may also continue.
[0202] FIG. 8 is a flowchart illustrating a control method of an electronic device (100) according to one embodiment of the present disclosure.
[0203] Referring to FIG. 8, the control method of the electronic device (100) of the present disclosure may include the step of detecting whether an object is inserted into the socket (150) (S10), the step of controlling the supply of current to the socket (150) for a preset galvanizing time (S20), the step of checking the value of the current flowing through the socket (150) for the galvanizing time (S30), and the step of controlling the switch (181) based on the current value to maintain the supply of current to the socket (S40).
[0204] The step (S20) of controlling the switch (181) during the galvanizing time may repeat a cycle in which the switch (181) is turned on for a preset first time and the switch (181) is turned off for a preset second time multiple times, and in this case, the step (S30) of checking the current value flowing through the socket (150) during the galvanizing time may check the current value measured after a preset number of initial cycles among the multiple cycles.
[0205] The step (S30) of checking the current value flowing through the socket (150) during the galvanizing time may specifically include the step (S25) of waiting during the first waiting time, which is the initial time during the galvanizing time, and in this case, the step (S30) of checking the current value measured after the step of waiting during the first waiting time may be performed.
[0206] The step (S30) of checking the current value flowing through the socket (150) during the galvanizing time can proceed to the step of maintaining the current supply to the socket (150) if the current value is between a first current value, which is a preset positive value, and a second current value, which is a preset negative value. If the current value is greater than or equal to the first current value or less than or equal to the second current value, the step (S35) of controlling the switch (181) to cut off the current supply to the socket (150) can proceed.
[0207] In this case, the determination of the current value described above can be calculated through the voltage value (Vm) of the galvanometer (180), and specifically, can be determined based on whether the voltage value (Vm) is a value between a first voltage value (V1), which is a preset positive value, and a second voltage value (V2), which is a preset negative value. The voltage value (Vm) may be an output value amplified through the amplifier (184) described above, or it may be the voltage value of the galvanometer resistor (183).
[0208] The step of cutting off the current supply (S35) may include the step of waiting for a preset second waiting time after turning off the switch (181) (S37), and then returning to the step of controlling the switch (181) for a galvanizing time (S20) to perform the galvanizing operation again.
[0209] When entering the step (S40) of maintaining the current supply to the socket (150) based on the current value flowing through the socket (150) during the galvanizing time, power can be supplied to the light source (40) coupled to the electronic device (100).
[0210] Therefore, the electronic device (100) and the control method thereof of the present disclosure cut off power to the socket (150) when a suitable light source (40) is not connected to the socket (150), and can supply power to the socket (150) only when a suitable light source (40) is connected to the socket (150). Through this, the electronic device (100) of the present disclosure may include multimedia functions, and can obtain safety standards as a multimedia device even if the light source (40) is manufactured or sold in a separated state.
[0211] In addition, when an unsuitable light source (40) is connected to the socket (150) of the electronic device (100) or an external object or the user's body is inserted, the power to the socket (150) is cut off by the control described above by the first sensor (160), the second sensor (170), the galvanometer (180), and the MCU (190) to prevent the risk of electric shock, and additionally, power is supplied to the socket (150) only when the connecting part (50) of the light source (40) is completely connected to the socket (150), thereby preventing the risk of electric shock that may occur while connecting a light bulb to the socket (150).
[0212] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications can be made by those skilled in the art to which the present disclosure belongs without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present disclosure.
