Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and more specifically, relates to a laser component and a laser display device. Background Technology

[0002] Laser display devices, such as laser projectors and laser TVs, use lasers as a light source to provide rich image colors. The laser needs to be connected to a driver circuit board via a connection structure to emit light. Currently, lasers and driver circuit boards are mostly connected using printed circuit boards (PCBs). In this connection method, the driver circuit board and the laser need to be coplanar, ensuring that the PCB connecting the driver circuit board and the laser is placed flat between them. Therefore, within laser display devices, the space requirements for the laser, driver circuit board, and PCB are high, the structural layout is limited, flexibility is poor, and it is not conducive to improving the utilization of the internal space of the device. Utility Model Content

[0003] The purpose of this application is to provide a laser component and a laser display device to solve the technical problems of poor flexibility in the layout of laser components and low utilization of internal space in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a laser component, comprising:

[0005] A connection structure, comprising a flexible plate, a first socket, and a second socket, wherein the first socket is disposed at a first end of the flexible plate, and the second socket is disposed at a second end of the flexible plate;

[0006] A laser, the laser comprising a substrate and a power socket disposed on the substrate, wherein a first socket is connected to the power socket;

[0007] A drive circuit board, and the second socket is connected to the drive circuit board.

[0008] The beneficial effects of the laser assembly provided in this application are as follows: Compared with the prior art, the laser assembly in this application connects the laser and the drive circuit board through a flexible plate. The flexibility of the flexible plate eliminates the need for the laser and drive circuit board to be flush, allowing for more flexible placement and contributing to a more compact layout within the equipment, thus improving the utilization rate of the internal space. Furthermore, the flexibility of the flexible plate also alleviates the tension after the first and second sockets are connected to the laser and drive circuit board respectively, thereby protecting the second and first sockets.

[0009] In some embodiments, power electrode lines are arranged on the flexible board, the wiring width of the power electrode lines is not less than 3 mm, and the wiring thickness of the power electrode lines is not less than 1 oz.

[0010] The first socket has an electrode connector that is electrically connected to the power electrode line; the power socket has multiple electrode pins for driving the light source, and the electrode connector is connected to the electrode pins.

[0011] By ensuring that the wiring width of the power electrode lines is no less than 3mm and the wiring thickness is no less than 1oz, it can be matched with higher power lasers.

[0012] In some embodiments, the first socket and the edge of the flexible plate have a first gap, the first gap being not less than 2 mm, and the laser further includes a temperature sensor disposed beside the power socket, the first gap being smaller than the gap between the power socket and the temperature sensor.

[0013] By ensuring that the first gap is not less than 2mm, it is convenient to process and manufacture the connection structure. The first gap is smaller than the gap between the power socket and the temperature sensor, so that after the power socket and the first socket are connected, the flexible board will not interfere with the temperature sensor.

[0014] In some embodiments, the first socket has a control signal connector, the power socket has a control signal pin connected to the temperature sensor, and the control signal connector is mated to the control signal pin;

[0015] The flexible board is provided with control signal lines, which are electrically connected to the control signal connector. The wiring width of the control signal lines is 0.1mm to 0.3mm.

[0016] By connecting the control signal connector and control signal pins, the drive circuit board can acquire information collected by the temperature sensor. The wiring width of the control signal line is 0.1mm to 0.3mm to ensure smooth signal transmission.

[0017] In some embodiments, the flexible plate has a first region corresponding to the first socket on the side opposite to the first socket, and a second region corresponding to the second socket on the side opposite to the second socket.

[0018] The laser assembly also includes a reinforcing plate, and at least one of the first and second regions is provided with the reinforcing plate.

[0019] By setting a reinforcing plate in at least one of the first and second regions, the strength of the corresponding region is improved, providing rigid support for the corresponding socket and facilitating patching and plugging / unplugging operations.

[0020] In some embodiments, the second region is provided with the reinforcing plate, and the flexible plate is provided with fixing holes that penetrate the reinforcing plate provided in the second region.

[0021] By setting fixing holes, the connection stability between the second socket and the drive circuit board can be strengthened directly by using the reinforcing plate in the second area.

[0022] In some embodiments, the fixing hole is an oval hole.

[0023] The oval hole has a certain linear movement space in the long axis direction, which allows the fastener to be positioned during fixing, compensates for the machining tolerance of the screw post, and facilitates assembly. After the first socket and the second socket are both plugged in and fixed, the oval hole can also relieve the tension on the flexible plate.

[0024] This application also provides a laser display device, including:

[0025] case;

[0026] The laser component, as described above, is installed within the housing.

[0027] By adopting the aforementioned laser components, the internal space utilization of laser display devices is higher, enabling both miniaturization and providing space for the addition of other structural components.

[0028] In some embodiments, the housing has a first mounting post, and fasteners pass through the fixing hole and are connected to the first mounting post.

[0029] In some embodiments, the laser display device further includes a clamping member connected to the housing to press the clamping member against the side of the flexible plate opposite to the first socket.

[0030] The clamping device provides additional force to the connection between the first socket and the power socket, strengthening the stability of the connection. Attached Figure Description

[0049] To make the technical problem to be solved, the technical solution and the beneficial effects clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0050] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0051] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the design.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the following description, "multiple" means two or more, unless otherwise explicitly specified.

[0053] like Figure 14 and Figure 15 As shown, the laser assembly includes a connection structure 100, a laser 200, and a driver circuit board 300. (See reference...) Figure 1 The connection structure 100 includes a flexible plate 110, a first socket 120, and a second socket 130. The first socket 120 is located at the first end of the flexible plate 110, and the second socket 130 is located at the second end of the flexible plate 110. (See attached...) Figures 7 to 10The laser 200 includes a substrate 210 and a power socket 220 disposed on the substrate 210. A first socket 120 is connected to the power socket 220, and a second socket 130 is connected to the drive circuit board 300. Thus, the laser 200 and the drive circuit board 300 are connected together by means of the flexible plate 110, the first socket 120 and the second socket 130.

[0054] See Figures 7 to 13 The laser 200 also includes a laser chip 251 and a lens array 252. (See also...) Figure 9 , Figure 10 , Figure 11 and Figure 12 A housing 241 is mounted on a substrate 210. A laser chip 251 and a lens array 252 are installed inside the housing 241, and a cover plate 242 closes the opening of the housing 241. A collimating lens 260 is mounted on the cover plate 242. The laser emitted by the laser chip 251 passes through the lens array 252 and then illuminates the collimating lens 260, where it is collimated. A power socket 220 is fixed to the substrate 210 and located beside the housing 241. There can be one or more housings 241. The multiple laser chips 251 installed inside the housing 241 can emit lasers of the same wavelength or different wavelengths.

[0055] The flexible board 110 is flexible and requires less installation space. Compared to the connection method using printed circuit boards, connecting the laser 200 and the driver circuit board 300 via the flexible board 110 eliminates the need for the laser 200 and driver circuit board 300 to be flush, allowing for more flexible placement and facilitating a more compact layout within the equipment, thus improving space utilization. Furthermore, the flexibility of the flexible board 110 can alleviate tension after the first socket 120 and the second socket 130 are connected to the laser 200 and driver circuit board 300 respectively, thereby protecting the second socket 130 and the first socket 120.

[0056] In some embodiments, the flexible board 110 is provided with power electrode lines, the wiring width of which is not less than 3 mm and the wiring thickness of which is not less than 1 oz. See also Figure 8 and Figure 13 The power socket 220 has electrode pins 221 for driving the light source. The first socket 120 has an electrode connector that mates with the electrode pins 221 and is electrically connected to the power electrode line.

[0057] The wiring width of the power supply electrode lines can be 3 mm or any value greater than 3 mm; the wiring thickness can be 1 oz or any value greater than 1 oz. If the wiring width is less than 3 mm and the wiring thickness is less than 1 oz, the current withstand capability of the power supply electrode lines is poor, making it difficult to match the operating current of the laser 200. Therefore, by controlling the wiring width and wiring thickness of the power supply electrode lines, it is ensured that the power supply electrode lines can withstand the operating current, pulse characteristics, and temperature rise requirements of the laser 200. Taking the operating current of the laser 200 as an example, to ensure that the power supply electrode lines can meet the operating current requirements, in some embodiments, the wiring width of the power supply electrode lines is 3 mm and the wiring thickness is 1 oz; in other embodiments, the wiring width of the power supply electrode lines is 3.5 mm. The wiring thickness of the power supply electrode lines is 2 oz.

[0058] The wiring width and thickness of the power electrode lines are positively correlated with the current withstand capability of the flexible board 110. In some embodiments, the wiring width of the power electrode lines is 3mm to 5mm, and the wiring thickness is 1oz to 3oz, minimizing the size of the connection structure 100 while meeting the laser's operating current requirements.

[0059] One end of the power electrode line is connected to the first socket 120 and the other end is connected to the second socket 130. The electrode pin 221 is connected to the drive circuit board 300 through the connection structure 100. The drive circuit board 300 transmits signals to the laser chip 251 through the power electrode line, electrode connector and electrode pin, driving the laser 200 to light up the laser.

[0060] Taking Laser 200 as an example, which is a red, green, and blue tri-color laser, please refer to... Figure 8 and Figure 13 The power socket 220 has six electrode pins 221, including two pins 221 for driving the red laser, two pins 221 for driving the green laser, and two pins 221 for driving the blue laser. These are respectively the positive and negative electrodes R+ and R- for driving the red laser, G+ and G- for driving the green laser, and B+ and B- for driving the blue laser. Correspondingly, six power electrode lines are arranged on the flexible board 110, each with a wiring width of not less than 3mm and a wiring thickness of not less than 1oz.

[0061] The power socket 220 is small, with a height of only 0.7mm. If a printed circuit board is used to connect the power socket 220 and the drive circuit board 300, the socket is easily damaged, leading to a disconnection. By using a flexible board 110 to connect the power socket 220 and the drive circuit board 300, the flexibility of the flexible board 110 can be used to flexibly adjust the arrangement between the power socket 220 and the drive circuit board 300. Furthermore, the flexibility of the flexible board 110 can alleviate the tension between the first socket 120 and the second socket 130 after they are plugged in, thus protecting the second socket 130 and the first socket 120.

[0062] In some embodiments, the first socket 120 and the edge of the flexible plate 110 have a first distance L1. The first distance L1 is not less than 2 mm. The laser 200 also includes a temperature sensor 230, which is disposed beside the power socket 220. The first distance L1 is smaller than the distance L2 between the power socket 220 and the temperature sensor 230.

[0063] See Figure 7 , Figure 8 and Figure 10 Temperature sensor 230 is positioned between power socket 220 and housing 241, relatively close to power socket 220. Temperature sensor 230 is used to read the operating temperature of laser 200, and the control system uses this temperature to adjust the heat dissipation of laser 200.

[0064] For example, the first distance L1 between the first socket 120 and the edge of the flexible board 110 is 2mm to 4mm. Specifically, the first distance L1 between the first socket 120 and the edge of the flexible board 110 is 2mm. Alternatively, the first distance L1 between the first socket 120 and the edge of the flexible board 110 may be 2.5mm, 2.8mm, 3.5mm, 4mm, or other values ​​between 2mm and 4mm.

[0065] If the first gap L1 formed by the first socket 120 and the edge of the flexible plate 110 is greater than the gap L2, the flexible plate 110 and the temperature sensor 230 will interfere after the first socket 120 is inserted into the power socket 220. If the first gap L1 formed by the first socket 120 and the edge of the flexible plate 110 is less than 2mm, the manufacturing process will be difficult to achieve. By ensuring that the gap between the edges of the first socket 120 and the flexible plate 110 is not less than 2mm and less than the gap L2, interference between the edge of the first socket 120 and the temperature sensor 230 after it is inserted into the power socket 220 can be prevented, and the process requirements can also be met. In addition, compared to a large gap, the gap between the edges of the first socket 120 and the flexible plate 110 is no more than 2mm, which not only meets the installation requirements of fixing the first socket 120 to the flexible plate 110, but also reduces the size of the flexible plate 110.

[0066] In some embodiments, the first socket 120 has a control signal connector, and the power socket 220 has a control signal pin 222. The control signal pin 222 is electrically connected to the temperature sensor 230, and the control signal connector is mated to the control signal pin 222. The flexible board 110 is also provided with control signal lines, which are electrically connected to the control signal connector. The wiring width of the control signal lines is 0.1mm to 0.3mm.

[0067] See Figure 8 and Figure 13 The power socket 220 in the laser 200 also has two control signal pins 222 for connecting to the temperature sensor 230, namely T+ and T-. After the first socket 120 is inserted into the power socket 220, the control signal connector mates with the control signal pins 222. In some embodiments, the wiring widths of the two control signal lines are the same, both being 0.1mm, 0.2mm, 0.3mm, or other values ​​between 0.1mm and 0.3mm.

[0068] In some embodiments, the control signal lines and power electrode lines are arranged on the same side of the flexible board 110. Arranging the control signal lines and power electrode lines on the same side of the flexible board 110 simplifies the wiring structure and reduces wiring costs.

[0069] In some embodiments, the wiring width of the control signal line is 8 mil, or 0.2032 mm.

[0070] In some embodiments, see Figures 4 to 6 The flexible plate 110 has a first region 111 corresponding to the first socket 120 on the side facing away from the first socket 120, and a second region 112 corresponding to the second socket 130 on the side facing away from the second socket 130. The connection structure 100 also includes a reinforcing plate 140, and at least one of the first region 111 and the second region 112 is provided with the reinforcing plate 140.

[0071] The side of the flexible plate 110 opposite to the first socket 120 is a first surface, and the side of the flexible plate 110 where the first socket 120 is located is a second surface. The first surface and the second surface are the two surfaces of the flexible plate 110. In one embodiment, see [reference needed]. Figures 1 to 3 The first socket 120 and the second socket 130 are both disposed on the second surface of the flexible plate 110 and located on the same side of the flexible plate 110. The first socket 120 and the second socket 130 are connected by power electrode lines and control signal lines.

[0072] When a reinforcing plate 140 is provided in the first region 111, the size of the reinforcing plate 140 in the first region 111 at least covers the projection of the first socket 120 onto the flexible plate 110. (See also...) Figures 1 to 3 The flexible plate 110 has a first side 115 and a second side 116 extending along the X direction, the first side 115 and the second side 116 being disposed opposite to each other. In some embodiments, see [reference needed]. Figure 4 and Figure 5 The opposite side edges of the reinforcing plate 140 provided in the first region 111 are flush with the first side 115 and the second side 116 respectively, so as to provide sufficient support for the first socket 120.

[0073] When a reinforcing plate 140 is provided in the second region 112, the size of the reinforcing plate 140 in the second region 112 at least covers the projection of the second socket 130 onto the flexible plate 110. (See also...) Figures 1 to 3 The flexible plate 110 has a third side 117 and a fourth side 118 extending along the X direction, and the third side 117 and the fourth side 118 are disposed opposite to each other. In some embodiments, see [reference] Figure 4 and Figure 6 The opposite side edges of the reinforcing plate 140 in the second region 112 are flush with the third side 117 and the fourth side 118, respectively.

[0074] It is understood that, in some embodiments, see Figure 3 The first side 115 and the third side 117 are collinear. In some other embodiments, see [reference needed]. Figure 1 and Figure 2 The first side 115 and the third side 117 are parallel. Similarly, in some embodiments, see [reference needed]. Figure 3 The second side 116 and the fourth side 118 are collinear. In some other embodiments, see [reference needed]. Figure 1 and Figure 2 The second side 116 and the fourth side 118 are parallel.

[0075] In some embodiments, see Figure 6 Only the first region 111 is provided with a reinforcing plate 140, which is located on the opposite side of the flexible plate 110 from the first socket 120. By providing the reinforcing plate 140 in the first region 111, rigid support can be provided for the insertion and removal operations of the first socket 120, facilitating connection with the socket on the laser 200. Furthermore, the flexible plate 110 is thin and flexible, and is prone to local deformation or warping during the placement process, leading to component misalignment or poor soldering. Therefore, by providing the reinforcing plate 140 in the first region 111, local support can also be provided for the placement of the first socket 120, preventing misalignment. In some embodiments, see [reference needed]. Figure 5Only the second region 112 is provided with a reinforcing plate 140, which is located on the opposite side of the flexible plate 110 from the second socket 130. By providing the reinforcing plate 140 in the second region 112, rigid support can be provided for the insertion and removal operations of the second socket 130, facilitating its connection with the drive circuit board 300. Furthermore, the flexible plate 110 is thin and flexible, and is prone to local deformation or warping during the surface mount process, leading to component misalignment or poor soldering. Therefore, providing the reinforcing plate 140 in the second region 112 also provides local support for the mounting of the second socket 130, preventing misalignment. In some other embodiments, see [reference needed]. Figure 4 Both the first area 111 and the second area 112 are equipped with reinforcing plates 140.

[0076] By providing a reinforcing plate 140 in at least one of the first region 111 and the second region 112, the reinforcing plate 140 can provide rigid support for the corresponding socket, facilitating the plugging and unplugging operation and surface mounting of the socket.

[0077] See Figures 4 to 6 A connecting region 113 is provided between the first region 111 and the second region 112, and the width of the connecting region 113 gradually decreases from the first region 111 to the second region 112. The width of the connecting region 113 refers to the length of the flexible board 110 along the Y direction, which is perpendicular to the X direction. In some embodiments, the connecting region 113 is trapezoidal, such as an isosceles trapezoid. By setting the width of the connecting region 113 to a shape that gradually decreases from the first region 111 to the second region 112, a smaller size of the flexible board 110 can be achieved while meeting wiring requirements.

[0078] With the reinforcement plate 140 installed in the second area 112, see [reference] Figures 1 to 6 The flexible plate 110 is provided with a fixing hole 150, which penetrates the reinforcing plate 140 provided in the second region 112.

[0079] The second socket 130 is larger than the first socket 120. To ensure the stability of the second socket 130's connection, a fixing hole 150 can be directly provided on the flexible plate 110. The fixing hole 150 provides a fastening position for the second socket 130's connection. Specifically, after the second socket 130 is inserted into the drive circuit board 300, a fastener passes through the fixing hole 150 to lock the flexible plate 110 onto the screw post. The reinforcing plate 140 provides a support surface for the fastener, preventing damage to the flexible plate 110. In addition to the connection between the second socket 130 and the drive circuit board 300, the fastener applies pressure to the second socket 130 through the reinforcing plate 140, enhancing the stability of the connection between the second socket 130 and the drive circuit board 300. The first socket 120 is small, making it difficult to provide holes for its connection.

[0080] The number of fixing holes 150 can be multiple. See, in some embodiments, [reference needed]. Figures 1 to 6 The flexible plate 110 has two fixing holes 150, each of which passes through the reinforcing plate 140 provided in the first region 111. During installation, two fasteners pass through the two fixing holes 150 one by one.

[0081] In some embodiments, the fixing hole 150 is an oblong hole, which has a certain linear movement space in the long axis direction, allowing the fastener to be adjusted in position during fixing and compensating for the machining tolerance of the screw post. When the flexible plate 110 has multiple fixing holes 150, the oblong hole can reduce the difficulty of aligning two fixing holes 150 with the corresponding screw post, facilitating assembly. In some embodiments, see [reference]. Figures 1 to 6 The X-direction extends from the first socket 120 to the second socket 130, and the long axis of the oval hole is along the X-direction, so that when the first socket 120 is connected to the laser 200 and the second socket 130 is connected to the drive circuit board 300, the tension on the flexible plate 110 can be relieved by means of the oval hole.

[0082] In addition, this application also provides a laser display device, which includes a housing and the connection structure 100 as described above. The laser 200, the driver circuit board 300, and the connection structure 100 are all mounted within the housing. See also... Figure 14 The laser 200 and the driver circuit board 300 are connected via the connection structure 100 as described above. Specifically, the first socket 120 is connected to the laser 200, and the second socket 130 is connected to the driver circuit board 300.

[0083] The laser display device is a laser TV or projector, etc., that has a laser 200. The laser 200 and the driving circuit board 300 are connected by the connection structure 100 as described above, so that the wiring of the flexible board 110 can meet the operating current of the laser 200. Furthermore, the flexible board 110 is flexible and has a relatively free assembly direction. Connecting the laser 200 and the driving circuit board 300 with the flexible board 110 can improve the freedom of the placement of components within the housing, which helps to achieve a compact layout and improve space utilization.

[0084] In some embodiments, multiple lasers 200 are arranged in parallel. Correspondingly, the end of the flexible plate 110 is provided with multiple first sockets 120, and the multiple first sockets 120 are connected to the multiple lasers 200 one by one. See reference. Figure 15 Multiple lasers 200 are connected to the drive circuit board 300 through a connection structure 100.

[0085] In some embodiments, the housing has a first mounting post, and fasteners pass through the fixing hole 150 and are connected to the first mounting post.

[0086] Fasteners pass through the fixing holes 150 to secure the reinforcing plate 140 in the second region 112 to the first mounting post. This strengthens the connection between the second socket 130 and the drive circuit board 300 by the pressure generated when the reinforcing plate 140 is connected to the housing. If there are multiple fixing holes 150, the first mounting post may have multiple fixing holes 150. For example, there may be two fixing holes 150 located on opposite sides of the reinforcing plate 140 along its length.

[0087] The laser chip 251 and lens array 252 within each housing 241 are arranged as follows: Figure 11 and Figure 12 As shown, multiple laser chips 251 are arranged at equal intervals. A lens array 252 is provided for each laser chip 251 to adjust the laser beam emitted by the laser chip 251. A transparent cover plate 242 covers the opening of the tube housing 241, allowing the laser beam to pass through the cover plate 242 after exiting the lens array 252 and then onto the collimating lens 260. (See reference...) Figures 7 to 10 The substrate 210 has two housings 241, and each housing 241 contains five laser chips 251, for a total of ten laser chips 251. Five laser chips 251 are used to provide red laser, three laser chips 251 are used to provide green laser, and two laser chips 251 are used to provide blue laser.

[0088] In some embodiments, the laser display device further includes a clamping member connected to the housing to press the clamping member onto the side of the flexible plate 110 opposite to the first socket 120.

[0089] Optionally, the housing has a second mounting post, and the clamping member has a mounting hole. Screws or other fasteners pass through the mounting hole and connect to the second mounting post to fix the clamping member inside the housing. With the locking force of the fastener, the clamping member is pressed against the side of the flexible plate 110 opposite to the first socket 120, enhancing the stability of the connection between the first socket 120 and the laser 200.

[0090] Optionally, the clamping element can be a metal or plastic component. In some embodiments, the clamping element is an elastic element, which helps to alleviate the force transmitted from the fixing element to the first socket 120, preventing the clamping element from applying excessive pressure to the first socket 120 and causing the first socket 120 to fail.

[0091] The above description is merely a preferred embodiment and is not intended to limit the scope of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
