Description

Technical Field

[0001] The present invention relates to the technical field of light sources, and particularly relates to a high-brightness linear light source. Background Art

[0002] As people's requirements for product precision are getting higher and higher, there are also higher requirements for product quality inspection. Photoelectric inspection has become a common inspection method; photoelectric inspection equipment largely depends on good light illumination. The three commonly used light sources in photoelectric inspection are point light sources, linear light sources, and surface light sources. Among them, linear light sources have the advantages of high brightness and uniform illuminance.

[0003] Traditional linear light sources usually choose to use either a water cooling system or an air cooling system as the heat dissipation module. However, after adjusting the brightness emitted by the linear light source, the heat generated by the linear light source is different; when the brightness of the linear light source is high and its heat dissipation requirement is high, due to the poor heat dissipation effect of the air cooling system, it is often necessary to use a water cooling system for cooling to meet the heat dissipation requirement. However, when the brightness of the linear light source is low and its heat dissipation requirement is low, since the water cooling system needs to install components such as water pumps, radiators, and pipes, its power consumption is relatively large, and the use of an air cooling system has a lower power consumption cost.

[0010] Furthermore, the housing includes a shell and end plates; the shell is provided with a through hole along the first direction; the circulation inlet, the circulation outlet, the heat dissipation slots and the liquid cooling channels are all arranged on the shell; there are two end plates, and they are respectively arranged on both sides of the shell, and an opening and a receiving cavity are defined between the two end plates and the shell.

[0011] Furthermore, the light emitting assembly further includes a light collecting rod; a slot is provided on the inner wall of the shell, and the slot is provided with a through hole along the first direction. A slider is arranged on the side end of the light collecting rod, and the slider is slidably arranged in the slot; the light collecting rod is located between the light emitting member and the transparent plate.

[0012] Furthermore, there are multiple slots, and they are arranged at intervals in the vertical direction; there are multiple light collecting rods, and the sliders of the multiple light collecting rods are respectively arranged in the multiple slots.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The light-emitting element is disposed in the accommodation cavity, and the light emitted by the light-emitting element can pass through the transparent plate and be emitted outward from the opening. During operation, the light-emitting element generates heat and transfers the heat to the housing. A liquid cooling channel is provided at the lower part of the housing. The liquid cooling component can input the circulating medium from the circulation inlet into the liquid cooling channel, so that the circulating medium can absorb the heat of the housing to dissipate the heat of the light-emitting element. The circulating medium in the liquid cooling channel can be discharged from the circulation outlet to carry away the heat. A heat dissipation groove is provided on the bottom end surface of the housing. By providing the heat dissipation groove, the contact area between the housing and the air can be increased to improve the heat dissipation efficiency of the housing. A heat dissipation fan is provided at the bottom end of the housing, and the heat dissipation fan is arranged towards the heat dissipation groove. The heat dissipation fan blows air towards the heat dissipation groove of the housing, so that the air flows to carry away the heat of the housing, and the heat dissipation effect on the housing and the light-emitting element is achieved. When the heat dissipation requirement is high, the liquid cooling component and the air cooling component can work simultaneously to meet the heat dissipation demand. When the heat dissipation requirement is low, either the liquid cooling component or the air cooling component can be used, and the use is relatively flexible.

[0017] 2. The length direction of the housing is the first direction. Both the heat dissipation groove and the liquid cooling channel extend along the first direction, so that the heat dissipation groove and the liquid cooling channel are relatively long. The flow path of the circulating medium in the liquid cooling channel is relatively long, and the contact area between the heat dissipation groove and the air is also relatively large, so as to further improve the heat dissipation effect. Both the heat dissipation groove and the liquid cooling channel are provided on the housing. After the housing is processed and produced, the heat dissipation groove and the liquid cooling channel are formed, so that the housing can be directly used in cooperation with the liquid cooling component and the air cooling component, and the installation process is relatively simple, so as to reduce the production and processing cost.

[0018] 3. Since the liquid cooling channel is located between the heat dissipation groove and the accommodation cavity, and the heat dissipation fan is arranged towards the heat dissipation groove, by providing the heat dissipation fan and the heat dissipation groove, the temperature of some parts around the liquid cooling channel can also be reduced, and the circulating medium can be cooled, thereby improving the heat transfer efficiency of the heat dissipated by the light-emitting element to the parts around the liquid cooling channel, and further improving the heat dissipation effect on the light-emitting element.

If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, if there is a description involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0031] Please refer to Figures 1 to 6, an embodiment of the present invention provides a high-brightness linear light source, which includes a housing 100, a light-emitting component, an air-cooling component 300, and a liquid-cooling component; the housing 100 is provided with an opening 101, a receiving cavity 102, a liquid-cooling channel 103, a circulation inlet 104, a circulation outlet 105, and a heat dissipation groove 106; the opening 101 is arranged at the top end of the housing 100 and is communicated with the receiving cavity 102; the heat dissipation groove 106 is arranged on the bottom surface of the housing 100; the liquid-cooling channel 103 is arranged in the lower part of the housing 100 and is located between the heat dissipation groove 106 and the receiving cavity 102; the circulation inlet 104 and the circulation outlet 105 are respectively communicated with both ends of the liquid-cooling channel 103; the length direction of the housing 100 is the first direction, and both the liquid-cooling channel 103 and the heat dissipation groove 106 extend along the first direction; the light-emitting component includes a transparent plate 200 and a light-emitting element; the transparent plate 200 is arranged at the opening 101; the light-emitting element is arranged in the receiving cavity 102; the air-cooling component 300 includes a cooling fan 310; the cooling fan 310 is arranged at the bottom end of the housing 100 and faces the heat dissipation groove 106; the liquid-cooling component is communicated with the circulation inlet 104 and the circulation outlet 105; the liquid-cooling component can input the circulating medium from the circulation inlet 104 into the liquid-cooling channel 103, and can receive the circulating medium discharged from the circulation outlet 105.

[0032] The light-emitting element is arranged in the receiving cavity 102, and the light emitted by the light-emitting element can pass through the transparent plate 200 and be emitted outward from the opening 101; the light-emitting element generates heat during operation and transfers the heat to the housing 100. The liquid-cooling channel 103 is arranged in the lower part of the housing 100, and the liquid-cooling component can input the circulating medium from the circulation inlet 104 into the liquid-cooling channel 103, so that the circulating medium can absorb the heat of the housing 100 to achieve a heat dissipation effect on the light-emitting element, and the circulating medium in the liquid-cooling channel 103 can be discharged from the circulation outlet 105 to take away the heat; the heat dissipation groove 106 is arranged on the bottom surface of the housing 100. By providing the heat dissipation groove 106, the contact area between the housing 100 and the air can be increased to improve the heat dissipation efficiency of the housing 100. A cooling fan 310 is arranged at the bottom end of the housing 100, and the cooling fan 310 faces the heat dissipation groove 106. The cooling fan 310 blows air flow towards the heat dissipation groove 106 of the housing 100, so that the air flows to take away the heat of the housing 100, achieving a heat dissipation effect on the housing 100 and the light-emitting element; when the heat dissipation requirement is high, the liquid-cooling component and the air-cooling component 300 can work simultaneously to meet the heat dissipation demand. When the heat dissipation requirement is low, either the liquid-cooling component or the air-cooling component 300 can work, and the use is relatively flexible.

[0033] The direction of the length of the housing 100 is the first direction. The heat dissipation grooves 106 and the liquid cooling channels 103 both extend along the first direction, so that the heat dissipation grooves 106 and the liquid cooling channels 103 are relatively long. The path of the circulating medium flowing in the liquid cooling channels 103 is long, and the area of the heat dissipation grooves 106 in contact with air is also large, so as to further improve the heat dissipation effect. The heat dissipation grooves 106 and the liquid cooling channels 103 are both arranged on the housing 100. After the housing 100 is processed and produced, the heat dissipation grooves 106 and the liquid cooling channels 103 are formed, so that the housing 100 can be directly used in cooperation with the liquid cooling component and the air cooling component 300, and the installation process is relatively simple, so as to reduce the production and processing cost.

[0034] Since the liquid cooling channels 103 are located between the heat dissipation grooves 106 and the accommodation cavity 102, and the heat dissipation fans 310 are arranged towards the heat dissipation grooves 106, by arranging the heat dissipation fans 310 and the heat dissipation grooves 106, the temperature of some parts around the liquid cooling channels 103 can also be reduced, and the circulating medium can be cooled, so as to improve the heat transfer efficiency of the heat dissipated by the light-emitting component to the parts around the liquid cooling channels 103, and further improve the heat dissipation effect on the light-emitting component.

[0035] Specifically, the waterproof and dustproof structure of the traditional linear light source open model is complex and the cost is relatively high. Moreover, it cannot be compatible with both water cooling and air cooling with one profile, and only two sets of die schemes can be made, increasing the die opening cost.

[0036] The high-brightness linear light source of the present invention can adopt an air-cooled and water-cooled integrated profile die. Using this high-brightness linear light source has three heat dissipation modes: air cooling, water cooling, and air cooling. The heat dissipation mode can be freely switched according to the use power or the use scenario, greatly reducing the die opening cost, and there is no need to re-open the die due to different heat dissipation methods.

[0037] Refer to Figure 1 and Figure 2 In some embodiments of the present invention, the air cooling component 300 further includes a mounting member 320; the mounting member 320 is connected to the heat dissipation fan 310 and is detachably connected to the housing 100.

[0038] By arranging the mounting member 320, the heat dissipation fan 310 can be installed at the bottom of the housing 100 to define the relationship between the heat dissipation fan 310 and the housing 100, and improve the working stability of the heat dissipation fan 310; the mounting member 320 is detachably connected to the housing 100 to be convenient for replacement and reduce the time required for maintenance.

[0039] Refer to Figure 2 、 Figure 3 and Figure 6, in some embodiments of the present invention, the mounting member 320 includes a connection structure, and there are two connection structures; connection grooves 107 are provided on both opposite sides of the housing 100, and the connection grooves 107 extend along the first direction; the mounting member 320 includes a support plate 321 and a connection plate 322, the two connection plates 322 are arranged opposite to each other and at intervals, and both ends of the support plate 321 are connected to the lower ends of the two connection plates 322 respectively; the two connection structures are detachably connected to the two connection plates 322 respectively, and are respectively detachably inserted into the two connection grooves 107; the support plate 321 is connected to the heat dissipation fan 310.

[0040] The heat dissipation fan 310 is installed on the support plate 321, and the support plate 321 can carry the heat dissipation fan 310. Among them, an air port penetrating up and down is opened in the middle of the support plate 321, and the heat dissipation fan 310 is fixedly installed at the air port to achieve an air ventilation effect.

[0041] The two connection plates 322 are respectively located on both sides of the housing 100. Connection grooves 107 are respectively provided on both sides of the housing 100. After the connection structure is connected to the connection plate 322, the connection structure penetrates into the connection groove 107 to be detachably connected to the housing 100, so as to limit the position of the mounting member 320, and thus limit the position of the heat dissipation fan 310 relative to the housing 100; the connection groove 107 extends along the first direction. When the heat at the bottom of the housing 100 is uneven, the connection structure can be disassembled, then the mounting member 320 is moved to a predetermined position, and then the connection structure is reinstalled to fix the position of the mounting member 320, so as to change the position of the heat dissipation fan 310, and the position with relatively high heat at the bottom of the housing 100 can be dissipated, improving the adaptability.

[0042] Among them, screw holes can be provided on the connection plate 322. The self-tapping screw design is adopted, the connection structure is a T-shaped screw, and the connection groove 107 is a T-shaped screw groove, which reduces the secondary processing cost of the profile.

[0043] Refer to Figures 1 to 3 , in some embodiments of the present invention, there are multiple mounting members 320, there are multiple heat dissipation fans 310, and the multiple mounting members 320 are connected to the multiple heat dissipation fans 310 one by one.

[0044] By providing multiple mounting members 320 and multiple heat dissipation fans 310, the heat dissipation effect can be further improved.

[0045] Specifically, the multiple heat dissipation fans 310 are arranged at intervals in sequence along the first direction so as to evenly dissipate heat from the bottom of the housing 100.

[0046] Refer to Figures 1 to 3 , in some embodiments of the present invention, there are multiple heat dissipation grooves 106, and they are arranged at intervals in sequence along the second direction; the first direction is perpendicular to the second direction.

[0047] The heat dissipation grooves 106 are arranged to extend along the first direction, which can extend the flow path of the gas in the heat dissipation grooves 106. By arranging a plurality of heat dissipation grooves 106, the area of the bottom of the housing 100 that can contact with air can be further increased, improving the heat dissipation effect; both the first direction and the second direction are horizontal directions.

[0048] Specifically, the heat dissipation grooves 106 are arranged to penetrate along the first direction, so that the air flow flows to the end of the heat dissipation grooves 106 and then flows out of the heat dissipation grooves 106, reducing heat accumulation.

[0049] Among them, the first direction is the length direction of the housing 100, and the second direction is the width direction of the housing 100.

[0050] Refer to Figure 1 、 Figure 5 and Figure 6 In some embodiments of the present invention, the housing 100 includes a housing body 110 and end plates 120; the housing body 110 is arranged to penetrate along the first direction; the circulation inlet 104, the circulation outlet 105, the heat dissipation grooves 106 and the liquid cooling channels 103 are all arranged on the housing body 110; there are two end plates 120, which are respectively arranged on both sides of the housing body 110, and an opening 101 and a receiving cavity 102 are defined between the two end plates 120 and the housing body 110.

[0051] The heat dissipation grooves 106 are arranged on the bottom end surface of the housing body 110, the liquid cooling channels 103 are arranged in the lower part of the housing body 110, and the circulation inlet 104 and the circulation outlet 105 are respectively arranged at both side ends of the lower part of the housing body 110, so that the circulation inlet 104 and the circulation outlet 105 can be communicated with the liquid cooling channels 103, and the flow path of the circulation medium in the liquid cooling channels 103 can be extended as much as possible.

[0052] The housing body 110 is arranged to penetrate along the first direction, so as to reduce the difficulty of installing parts into the receiving cavity 102, reducing the assembly difficulty and assembly time; the two end plates 120 are installed at the through openings formed by the penetration of the housing body 110, so that the two end plates 120 and the housing body 110 form the housing 100, and an opening 101 and a receiving cavity 102 can be defined.

[0053] Among them, the housing 100 may further include a pressing plate structure, and the pressing plate structure can be installed at the top of the housing 100. A sealing gasket slot is provided at the top of the housing body 110. After placing the transparent plate 200 on the housing body 110, the sealing gasket can be placed into the sealing slot, and then the pressing plate structure covers the top of the housing body 110, achieving a dust and waterproof design.

[0054] Refer to Figure 3 、 Figure 4 and Figure 6, in some embodiments of the present invention, the light-emitting component further includes a light condensing rod 210; a slot 108 is provided on the inner wall of the housing 110, the slot 108 runs through in the first direction, a slider 211 is provided on the side end of the light condensing rod 210, and the slider 211 is slidably arranged in the slot 108; the light condensing rod 210 is located between the light-emitting element and the transparent plate 200.

[0055] By installing the light condensing rod 210 between the light-emitting element and the transparent plate 200, the brightness can be improved, making the light spot more concentrated to improve the detection effect.

[0056] The housing 110 runs through, and a slot 108 is provided on the inner wall of the housing 110. When the light condensing rod 210 needs to be installed, the slider 211 on the side end of the light condensing rod 210 can be slid into the slot 108, reducing the installation difficulty, and having relatively high connection stability, improving the work safety.

[0057] Specifically, there are two slots 108, the two slots 108 are arranged oppositely, sliders 211 are provided on both sides of the light condensing rod 210, and the two sliders 211 are respectively slidably installed in the two slots 108, further providing the installation stability.

[0058] Refer to Figure 3 、 Figure 5 and Figure 6 , in some embodiments of the present invention, there are multiple slots 108, and they are arranged at intervals in the vertical direction; there are multiple light condensing rods 210, and the sliders 211 of the multiple light condensing rods 210 are respectively arranged in the multiple slots 108.

[0059] By providing multiple slots 108 arranged at intervals in the vertical direction, multiple light condensing rods 210 can be installed. The light emitted by the light-emitting element can be focused multiple times, making the light emitted by the light-emitting element have better brightness and a more concentrated light spot.

[0060] Among them, the vertical direction is set in the same direction as the height direction of the outer shell 100, and the adjacent light condensing rods 210 are arranged at intervals.

[0061] Refer to Figure 3 and Figure 4 , in some embodiments of the present invention, since the liquid cooling channel 103 is arranged at the lower part of the outer shell 100, the heat dissipation slots 106 are arranged on the bottom end surface of the outer shell 100, and the heat dissipation direction at the bottom of the outer shell 100 is set towards the heat dissipation slots 106, and the light-emitting element is arranged on the bottom wall of the accommodating cavity 102, so that the heat dissipated by the light-emitting element can be transferred to the bottom of the outer shell 100 more. Through the cooperation of the liquid cooling component, the air cooling component 300 and the heat dissipation slots 106, the heat dissipation efficiency can be further improved.

[0062] Specifically, the liquid cooling channel 103 is separated from the accommodation cavity 102. The liquid cooling channel 103 is located below the bottom wall of the accommodation cavity 102. The heat dissipation groove 106 is separated from the liquid cooling channel 103. The heat dissipation groove 106 is located below the liquid cooling channel 103. The light-emitting component is arranged on the bottom wall of the accommodation cavity 102 and abuts against the bottom wall of the accommodation cavity 102, so that more heat dissipated by the light-emitting component will be transferred to the lower part of the housing 100, enabling the liquid cooling component and the air cooling component to better dissipate heat from the housing 100.

[0063] In some embodiments of the present invention, there is also a temperature sensing component and a control component; the temperature sensing component is arranged in the accommodation cavity 102, and the temperature sensing component is used to detect the temperature of the light-emitting component; the control component is connected to the housing 100 and is electrically connected to the temperature sensing component, the air cooling component 300, and the liquid cooling component.

[0065] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
