Abstract
Description
Technical Field
[0001] This application relates to the field of machine vision technology, and in particular to a light source. Background Technology
[0002] Machine vision light sources in industrial lighting technology typically consist of a lamp board, a circuit board, and a heat dissipation structure. The circuit board is generally mounted rear-mounted opposite the lamp board, which severely limits the space available for the heat dissipation structure on the back of the lamp board. This restricts the heat dissipation capacity of the light source, resulting in higher temperatures during operation. High temperatures can cause the lamp board to malfunction and shorten its lifespan. To ensure the normal operation of the lamp board, it is impossible to use high-power LEDs to provide high-brightness supplemental lighting, thus hindering the achievement of high-power illumination.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0036] As mentioned in the background section, machine vision light sources in the field of industrial lighting technology typically include a lamp board, a circuit board, and a heat dissipation structure. The circuit board is generally mounted rear-mounted opposite the lamp board, which greatly limits the space available for the heat dissipation structure on the back of the lamp board. This restricts the heat dissipation capacity of the light source, resulting in higher temperatures during operation. High temperatures can cause the lamp board to malfunction and shorten its lifespan. To ensure the normal operation of the lamp board, it is impossible to use high-power LEDs to provide high-brightness supplementary lighting, thus hindering the achievement of high-power illumination.
[0037] To improve heat dissipation efficiency and achieve high-power lighting, this application provides a light source, which will be described in detail below.
[0038] like Figures 1 to 3 As shown, the light source includes: mounting plate 100a, side plate 100b, lamp plate 200, heat dissipation component 300 and control component 400.
[0039] Mounting plate 100a has a first mounting surface 111 and a second mounting surface 112. Side plate 100b is located on the side of mounting plate 100a.
[0040] The lamp panel 200 is mounted on the first mounting surface 111 of the mounting plate 100a. The heat dissipation assembly 300 is located on the second mounting surface 112 of the mounting plate 100a, opposite to the middle of the lamp panel 200, and is used to dissipate heat from the lamp panel 200.
[0041] The control component 400 is mounted on the second mounting surface 112 of the mounting plate 100a, located in the control component mounting area 130 formed between the heat dissipation component 300 and the side plate 100b.
[0042] Compared to the prior art where the circuit board is mounted in a rear-mounted manner opposite to the lamp board, the embodiment of this application places the heat dissipation component 300 opposite to the middle of the lamp board 200, and the control component 400 between the heat dissipation component 300 and the side plate 100b, so that the middle area of the lamp board 200 can be dissipated by the heat dissipation component 300, thereby improving the heat dissipation efficiency and enabling the lamp board 200 to work normally under high power conditions, thus realizing high-power lighting.
[0043] Specifically, existing technologies typically employ a design scheme with fixed structural components such as mounting plates, side plates, and heat dissipation assemblies, resulting in a complex assembly process and high precision requirements for each component. To address this issue, such as... Figure 3 As shown, the mounting plate 100a, side plate 100b, and heat dissipation assembly 300 in this embodiment are integrally molded structures, specifically manufactured by extruding profiles. Integrating the components allows for maximum integration, simplifying the manufacturing and assembly process. After material integration, hidden costs in material management, quality inspection, and warehousing are reduced; fewer parts lead to improved assembly efficiency and lower manufacturing costs.
[0044] like Figure 2 As shown, the heat dissipation component 300 is fully disposed on the second mounting surface 112 of the mounting plate 100a, extending from one end of the mounting plate 100a to the other end, so as to increase the proportion of the heat dissipation component 300 on the mounting plate 100a and improve the heat dissipation effect.
[0045] This application does not limit the type or shape of the light source. The light source can be... Figure 1 The strip light source shown can also be a circular light source or other shapes. Regardless of the shape of the light source, the heat dissipation component 300 can be placed in the middle, directly opposite the lamp panel 200, and the control component 400 can be placed at the edge, in accordance with the above arrangement, to improve heat dissipation efficiency.
[0046] Next, let's start with... Figures 1 to 6 The specific structure of the strip light source shown will be explained.
[0047] Let the length direction of the bar light source be denoted as the x-direction, and the width direction as the y-direction. For example... Figure 2 As shown, there are two side plates 100b of the strip light source. The two side plates 100b are parallel to the x-direction and are set opposite each other on the two long sides of the mounting plate 100a, and are integrally formed with the mounting plate 100a.
[0048] End caps 810 are provided at the left and right ends of the two side plates 100b. The end caps 810 and the side plates 100b surround the mounting plate 100a, forming a first mounting space on the first side of the mounting plate 100a for mounting the lamp panel 200; and forming a second mounting space on the second side of the mounting plate 100a. The second mounting space is divided into a heat dissipation area 140 in the middle for mounting the heat dissipation component 300, and a control component mounting area 130 on the edge for mounting the control component 400.
[0049] like Figure 1 , Figure 3 and Figure 4 As shown, the light source also has a diffuser plate 600, which is disposed in the first mounting space, fixedly connected to the two side plates 100b, and located on the side of the lamp plate 200 away from the heat dissipation component 300. A lamp plate retaining strip 700 is provided between the diffuser plate 600 and the lamp plate 200 to press the lamp plate 200 firmly onto the mounting plate 100a.
[0050] Since electronic components are located on the back of the lamp board 200, direct hard contact with the mounting plate 100a could damage these components. To avoid this, such as... Figure 3 As shown, the mounting plate 100a of this application embodiment is provided with a recessed filling area 150 for filling a soft thermal pad, so that the area on the back of the lamp board 200 where electronic components are mounted is in contact with the thermal pad, which can not only avoid damage to the electronic components, but also improve the heat dissipation effect through the thermal pad.
[0051] like Figure 2 and Figure 5 As shown, the light source also has a rear cover 820, which covers the control component mounting area 130 and is detachably fixedly connected to the heat dissipation component 300 and the side plate 100b, in order to protect the control component 400 and avoid interference from the external environment.
[0052] There are various ways to arrange the heat dissipation area 140 and the control component mounting area 130, such as... Figure 6 As shown, the control component mounting area 130 is located on both sides of the heat dissipation area 140 along the x-direction or y-direction, or it can be located only on one side of the heat dissipation area 140 along the x-direction or y-direction; this application does not limit this arrangement. Regardless of the arrangement, as long as the heat dissipation area 140 covers the central area of the lamp panel 200, and the control component mounting area 130 covers the edge area of the lamp panel 200, or does not cover the lamp panel 200 at all, the lamp panel temperature can be avoided due to limited space for the heat dissipation structure on the back of the lamp panel, thus improving the heat dissipation capacity of the light source and enabling the lamp panel 200 to operate normally at higher power to achieve high-power lighting. In addition, the control component mounting area 130 covering the edge area of the lamp panel 200, or not covering the lamp panel 200 at all, can also reduce the heat transferred to the control component 400, preventing the control component 400 from overheating.
[0053] In other embodiments of this application, taking a circular light source as an example, both the lamp plate 200 and the mounting plate 100a are circular, and the side plate 100b is an annular side plate that surrounds the mounting plate 100a. In this embodiment, the heat dissipation assembly 300 and the control assembly 400 can also be arranged in the above manner, and will not be described again here. (The following will refer to...) Figures 1 to 6 The example shown is a bar light source.
[0054] This application does not limit the specific form of the heat dissipation component 300. The heat dissipation component 300 can adopt... Figure 2 The heat dissipation fins shown can also be replaced by other forms such as heat pipes. The heat dissipation assembly 300 using the heat dissipation fins form will be described in detail below.
[0055] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the heat dissipation component 300 includes a plurality of heat dissipation teeth 310.
[0056] Multiple heat dissipation teeth 310 are spaced apart on the second mounting surface 112 of the mounting plate 100a and extend toward a direction away from the lamp panel 200, so that the heat generated by the lamp panel 200 passes through the mounting plate 100a and is transferred to the external environment by the heat dissipation teeth 310.
[0057] In the embodiments of this application, the heat dissipation component 300 adopts the form of heat dissipation teeth 310, which has a simple structure and can be manufactured integrally with the mounting plate 100a, simplifying the preparation and installation process. With the above arrangement, one end face of the heat dissipation teeth 310 contacts the mounting plate 100a to receive heat transferred from the mounting plate 100a, while the other faces are in contact with the external environment, resulting in a large heat dissipation area and thus improving heat dissipation efficiency.
[0058] The multiple heat dissipation fins 310 can be arranged in the following three forms:
[0059] Multiple heat dissipation teeth 310 can be arranged in a row along the x direction, with each row having one heat dissipation tooth 310. The heat dissipation tooth 310 is arranged along the y direction, extending from one end of the width direction of the heat dissipation area 140 to the other end.
[0060] Multiple heat dissipation teeth 310 can also be arranged in a row along the y direction, with one heat dissipation tooth 310 in each row. The heat dissipation tooth 310 is arranged along the x direction, extending from one end of the heat dissipation area 140 to the other end along its length.
[0061] Multiple heat dissipation fins 310 can also be arranged in an array in the heat dissipation area 140, with multiple heat dissipation fins 310 in each row or column. For example Figure 2 As shown, compared to the two arrangement methods mentioned above, the array arrangement, with its more smaller heat dissipation teeth and more heat dissipation channels, can further increase the contact area between the light source and the external environment, thereby improving heat dissipation efficiency. On the other hand, it allows the heat generated by the lamp board 200 to be transferred to the heat dissipation component 300 and then dispersed along more heat dissipation channels, making the heat distribution on the heat dissipation component 300 more uniform, thus avoiding localized high temperatures and maximizing the natural heat dissipation efficiency of the heat dissipation component 300.
[0062] The following is a detailed description of an embodiment employing an array of heat dissipation fins 310.
[0063] In some embodiments of this application, such as Figure 2 , Figure 6 and Figure 7 As shown, multiple heat dissipation teeth 310 are arranged in an array, and a first horizontal heat dissipation channel 320 is formed between adjacent rows of heat dissipation teeth 310, and a first vertical heat dissipation channel 330 is formed between adjacent columns of heat dissipation teeth 310, so that the heat generated by the lamp panel 200 can be transferred along the first horizontal heat dissipation channel 320 and the first vertical heat dissipation channel 330.
[0064] The side panel 100b is provided with at least one set of ventilation holes 121. The at least one set of ventilation holes 121 is opposite to the first transverse heat dissipation channel 320 or the first longitudinal heat dissipation channel 330, so that the heat generated by the lamp panel 200 is transferred to the ventilation holes 121 along the first transverse heat dissipation channel 320 or the first longitudinal heat dissipation channel 330, and then transferred to the external environment through the ventilation holes 121.
[0065] For example, in Figure 2In the illustrated strip light source embodiment, there are two sets of ventilation holes 121, each opposite to one of the two first longitudinal heat dissipation channels 330. In other embodiments of this application, the two side plates 100b may also be parallel to the y-direction and disposed opposite each other on the two wide sides of the mounting plate 100a. In this case, the ventilation holes 121 are opposite to the first transverse heat dissipation channels 320.
[0066] Compared to the heat dissipation fins 310 which only dissipate heat through radiation to transfer heat to the external environment, this embodiment of the application opens ventilation holes 121 on the side plate, which are opposite to the first transverse heat dissipation channel 320 or the first longitudinal heat dissipation channel 330, so that convection can be formed inside the light source, thereby improving the heat dissipation efficiency and greatly improving the heat dissipation capacity of the light source, which can support high-power, high-brightness light source supplementary lighting.
[0067] To further improve heat dissipation efficiency, in some embodiments of this application, such as... Figure 3 and Figure 6 As shown, multiple auxiliary heat dissipation teeth 131 are also arranged at intervals in the control component mounting area 130 on the mounting plate 100a.
[0068] Multiple auxiliary heat dissipation teeth 131 are integrally set or fixedly connected to the mounting plate 100a and extend in a direction away from the lamp panel 200, so that the heat generated by the lamp panel 200 passes through the mounting plate 100a and is transferred to the external environment by the auxiliary heat dissipation teeth 131.
[0069] Multiple auxiliary heat dissipation teeth 131 can also be integrally formed with the mounting plate 100a to simplify the manufacturing and assembly process. The auxiliary heat dissipation teeth 131 can be parallel to the heat dissipation teeth 310 to make the back structure of the light source simple and aesthetically pleasing, and easy to manufacture.
[0070] By adding auxiliary heat dissipation teeth 131 to the embodiments of this application, the contact area between the light source and the external environment can be increased, thereby further improving the heat dissipation efficiency. When the auxiliary heat dissipation teeth 131 and the mounting plate 100a are integrally set, the preparation and installation process can also be simplified.
[0071] In some embodiments of this application, such as Figure 6 As shown, multiple auxiliary heat dissipation teeth 131 are arranged in an array, and a second horizontal heat dissipation channel 132 is formed between adjacent rows of auxiliary heat dissipation teeth 131, and a second vertical heat dissipation channel 133 is formed between adjacent columns of auxiliary heat dissipation teeth 131.
[0072] With multiple heat dissipation fins 310 arranged in an array, a first transverse heat dissipation channel 320 is formed between adjacent rows of heat dissipation fins 310, and a first longitudinal heat dissipation channel 330 is formed between adjacent columns of heat dissipation fins 310. The side plate 100b is provided with at least one set of ventilation holes 121, and at least one set of ventilation holes 121 is opposite to either the first transverse heat dissipation channel 320 or the first longitudinal heat dissipation channel 330.
[0073] In such Figure 2 and Figure 6 When the side plate 100b is disposed opposite to the two long sides of the mounting plate 100a, the two ends of the second longitudinal heat dissipation channel 133 are respectively opposite to the ventilation hole 121 and the first longitudinal heat dissipation channel 330, so that the heat generated by the lamp plate 200 is transferred to the ventilation hole 121 in sequence along the first longitudinal heat dissipation channel 330 and the second longitudinal heat dissipation channel 133.
[0074] Alternatively, when the side plate 100b is disposed opposite to the two wide sides of the mounting plate 100a, the two ends of the second transverse heat dissipation channel 132 are respectively opposite to the ventilation hole 121 and the first transverse heat dissipation channel 320, so that the heat generated by the lamp plate 200 is transferred to the ventilation hole 121 in sequence along the first transverse heat dissipation channel 320 and the second transverse heat dissipation channel 132.
[0075] In this embodiment of the application, both the heat dissipation teeth 310 and the auxiliary heat dissipation teeth 131 are arranged in an array to form more heat dissipation channels, further increasing the contact area between the light source and the external environment, thereby improving heat dissipation efficiency. Furthermore, the auxiliary heat dissipation teeth 131, positioned between the side plate 100b and the heat dissipation assembly 300, can guide the heat flowing out from the first transverse heat dissipation channel 320 or the first longitudinal heat dissipation channel 330, preventing heat from dissipating to both sides at the channel openings and accelerating the heat transfer to the ventilation hole 121, thus improving heat dissipation efficiency.
[0076] In some embodiments of this application, such as Figure 6 As shown, when the two ends of the second horizontal heat dissipation channel 132 are opposite to the ventilation hole 121 and the first horizontal heat dissipation channel 320 respectively, the width of the second horizontal heat dissipation channel 132 is not less than the width of the first horizontal heat dissipation channel 320.
[0077] When the two ends of the second longitudinal heat dissipation channel 133 are opposite to the ventilation hole 121 and the first longitudinal heat dissipation channel 330 respectively, the width of the second longitudinal heat dissipation channel 133 is not less than the width of the first longitudinal heat dissipation channel 330.
[0078] By applying the above settings, setting a higher density for the heat dissipation fins 310 increases the number of the first horizontal heat dissipation channels 320 or the first vertical heat dissipation channels 330, allowing heat to be dispersed and transferred along more channels, resulting in a more uniform heat distribution on the heat dissipation assembly 300 and preventing localized high temperatures. Setting a lower density for the auxiliary heat dissipation fins 131 increases the width of the second horizontal heat dissipation channel 132 or the second vertical heat dissipation channel 133, allowing heat flowing out from the first horizontal heat dissipation channel 320 or the first vertical heat dissipation channel 330 to be transferred to the ventilation holes 121 more quickly, thereby improving heat dissipation efficiency.
[0079] In practical applications, there are requirements for the size of the light-emitting area of the light source, but the installation space for the light source is limited. The size of the frame outside the light-emitting area of the light source is related to the position of the control component mounting area 130. If the control component mounting area 130 is set off to a less desirable location, the overlap between it and the projection of the lamp board 200 onto the mounting plate 100a will be smaller, resulting in a larger size for the mounting plate 100a, i.e., a larger frame size outside the light-emitting area of the light source.
[0080] To ensure that the light source meets both the limitations of installation space and the needs of large-scale lighting, such as Figure 3 As shown, the projected size of the heat dissipation component 300 on the mounting plate 100a is smaller than the projected size of the lamp board 200 on the mounting plate 100a.
[0081] The projection of the control component 400 onto the mounting plate 100a partially overlaps or completely overlaps with the projection of the light panel 200 onto the mounting plate 100a. A larger overlap area results in a smaller light source size, but reduces heat dissipation. Therefore, the proportion of the overlap can be set according to the actual scenario to ensure the light source size is close to the limit of the installation space, thereby minimizing the overlap area and maximizing heat dissipation.
[0082] like Figure 3 As shown, the projection portions of the control component 400 and the lamp panel 200 on the mounting plate 100a are nearly completely overlapped. At this time, the light-emitting area of the light source accounts for the highest proportion, which is L1 / (L1+2L2). Wherein, L1 is the width of the lamp panel 200 and L2 is the width of the side plate.
[0083] By applying the above arrangement, the frame size outside the front light-emitting area of the light source is minimized, achieving an extremely narrow frame effect in the front light-emitting area of the light source. This greatly reduces the assembly space constraints at the customer's site and can better cope with customers' scenarios requiring minimal installation space.
[0084] In some embodiments of this application, such as Figure 6 As shown, the control component 400 includes a power supply main board 410 and a signal main board 420.
[0085] The power supply mainboard 410 and signal mainboard 420 are located in the control component mounting area 130, both contacting the heat dissipation component 300 and the side plate 100b. Both the power supply mainboard 410 and signal mainboard 420 pass through the mounting plate 100a and are electrically connected to the lamp board 200. The power supply mainboard 410 is electrically connected to an external power supply, the lamp board 200, and the signal mainboard 420, providing power to them. The signal mainboard 420 is also electrically connected to an external controller, enabling it to send signals to the power supply mainboard under the control of the external controller to control the switching and brightness of the lamp board 200.
[0086] The relative positions of the power supply motherboard 410 and signal motherboard 420 to the heat dissipation assembly 300 are related to the arrangement of the control component mounting area 130. The power supply motherboard 410 and signal motherboard 420 can be located on the same side of the heat dissipation assembly 300, or they can be arranged as follows: Figure 6 As shown, they are located on both sides of the heat dissipation assembly 300.
[0087] exist Figure 6 In the embodiment shown, the light panel 200 is a strip light panel, and the control component mounting area 130 includes a power supply main board mounting area 130a and a signal main board mounting area 130b, which are used to mount the power supply main board 410 and the signal main board 420 respectively.
[0088] The power supply motherboard mounting area 130a and the signal motherboard mounting area 130b are respectively located on both sides of the heat dissipation assembly 300 along the width direction of the lamp board 200.
[0089] Compared to the control component being a single motherboard with a rear-mounted design opposite the lamp board, the control component 400 in this embodiment adopts a split layout, which is narrowed and distributed on both sides of the whole machine. This allows the heat dissipation area on the back of the lamp board 200 to be fully released, improves the effective utilization space of the heat dissipation component 300, and achieves good heat dissipation under high power conditions.
[0090] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the end cover 810 is provided with a power interface 510 and a signal interface 520. The power interface 510 corresponds to the position of the power supply motherboard mounting area 130a, and the signal interface 520 corresponds to the position of the signal motherboard mounting area 130b. The power supply motherboard 410 is connected to an external power supply through the power interface 510, and the signal motherboard 420 is connected to an external controller through the signal interface 520.
[0091] In some embodiments of this application, the light panel 200 may be a single light panel or may include multiple sub-light panels 210. The number of control components 400 may be one, controlling the entire light panel or controlling all the sub-light panels 210; or there may be multiple control components 400, with each control component 400 responsible for controlling only one sub-light panel 210.
[0092] like Figure 9 As shown, when the lamp panel 200 includes multiple sub-lamp panels 210, the multiple sub-lamp panels 210 are sequentially spliced on the mounting plate 100a along the length direction of the lamp panel 200.
[0093] The number of control components 400 is the same as the number of lamp panels 200. The power supply mainboards 410 of each group of control components 400 are spaced apart along the length of the lamp panel 200 within the power supply mainboard mounting area 130a, and each power supply mainboard 410 is electrically connected to a corresponding sub-lamp panel 210. The signal mainboards 420 of each group of control components 400 are spaced apart along the length of the lamp panel 200 within the signal mainboard mounting area 130b, and each signal mainboard 420 is electrically connected to a corresponding sub-lamp panel 210.
[0094] like Figure 6 As shown, auxiliary heat dissipation fins 131 can be provided in the interval between two adjacent power supply motherboards 410 and / or two adjacent signal motherboards 420, and ventilation holes 121 can be opened at the positions corresponding to the interval. This can prevent the ventilation holes 121 from being blocked by the motherboard, shorten the heat transfer path, and improve heat dissipation efficiency.
[0095] By applying the embodiments of this application, both the sub-lamp board 210 and the control component 400 can be set as standard parts. According to the actual scene's requirements for the size of the light-emitting area, the profile length can be cut to the required length. The lamp board 200 and the control component 400 can be modularly designed as described above and spliced together to form a light source of the required length, making the preparation and installation processes simple and convenient.
[0096] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
