[0003] Because the light source device adopts the way of parallel arrangement of lamp beads, the light of lamp beads adopts the way of direct radiation, and in order to ensure the brightness of irradiation, the arrangement between lamp beads is relatively dense, so that the irradiation of the light source is more dazzling, which affects the checking. After the dense arrangement of lamp beads, a large amount of heat generated by lamp beads cannot be discharged in time, thereby affecting the service life of lamp beads.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a light source device for detection to solve the problems of the light of lamp beads in the prior art adopting the way of direct radiation, the irradiation of the light source being more dazzling, and the heat generated by lamp beads affecting the service life of lamp beads.

[0006] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0007] A light source device for detection;

[0008] It comprises a mounting plate, a light source assembly obliquely arranged in parallel on the mounting plate, a heat dissipation mechanism arranged below the mounting plate, and a gas blowing device arranged below the heat dissipation mechanism.

[0009] Among them, adjacent light source assemblies are staggered; the heat dissipation mechanism is curved and connected to the gas blowing end of the gas blowing device; the gas blowing device blows gas into the heat dissipation mechanism, and the gas carries the heat of the light source assembly out of the heat dissipation mechanism.

[0010] Further technical solutions are that the mounting plate is formed with mounting strips in parallel; the mounting strips are formed with inclined surfaces in relative oblique; and the light source assemblies are staggered on the inclined surfaces of the mounting strips.

[0011] Further technical solutions are that the bottom surface of the mounting plate is formed with a flow guide groove near the mounting strips; and the depth of the flow guide groove gradually decreases from the middle to both sides along the gas flow direction.

[0012] A further technical solution is that the heat dissipation mechanism includes: a main body and a diffuser connected to each other; the diffuser is bent and connected to the main body; a first channel is formed on the upper surface of the main body, and a second channel is formed inside the diffuser; the first channel is connected to the guide groove; the second channel is connected to the first channel and the air blowing end of the air blowing device respectively.

[0013] A further technical solution is that the width of the second channel gradually increases along the gas flow direction.

[0014] A further technical solution is that the light source assembly is installed by a fixing component; the fixing component includes a fixing bracket and a fixing member; the fixing member passes through the fixing bracket and is threadedly connected to the mounting strip; after tightening the fixing member, the fixing bracket presses the light source assembly.

[0015] A further technical solution is that the fixing bracket includes a connecting piece and elastic pieces connecting both sides of the connecting piece; the fixing member passes through the connecting piece; after tightening the fixing member, the elastic pieces press the light source assembly.

[0016] A further technical solution includes an air extraction device; the heat dissipation mechanism is bent and connected to the air extraction end of the air extraction device; the air extraction device extracts the gas blown into the heat dissipation mechanism.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) The light source component is set at an angle, and the light from the relatively set light source component is concentrated, which improves the illumination brightness of the light source device for detection. At the same time, the light generated by the light source component is not a straight line, and the light is relatively soft. The heat of the light source component is transferred to the mounting plate, and the blowing device blows gas into the heat dissipation mechanism. The gas drives the heat of the light source component to be discharged from the heat dissipation mechanism.

[0018] (2) Since the heat dissipation mechanism is set at the lower end of the mounting plate in the left and right direction, the gas generated by the blowing device flows in the left and right direction below the mounting plate; the heat generated by the light source component is transferred to the mounting strip and the mounting plate in sequence. When the gas generated by the blowing device flows along the heat dissipation mechanism, it enters the guide groove, and the gas carries out the heat of the mounting plate in the guide groove.

[0019] (3) The elastic sheet protrudes and bends towards the light source assembly; the fixed bracket is placed on the mounting strip, and the fixing piece passes through the connecting piece. At this time, the elastic sheet contacts the light source assembly; after tightening the fixing piece, the elastic sheet elastically presses the light source assembly; the elastic sheet can continuously form elastic pressure on the light source assembly to prevent the light source assembly from becoming loose.

[0020] (4) By using an air extraction device to extract the heat dissipation mechanism and blow in the gas, the gas flow rate in the heat dissipation mechanism is increased, and the heat generated by the light source component is quickly discharged. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the device proposed by this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, only used to conveniently and clearly assist in illustrating the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0026] Figure 1 A schematic diagram of the structure of the detection light source device according to the first embodiment of this utility model is shown. Figure 2 It shows Figure 1 Enlarged structural diagram of the fixed component in the middle. (Combined with...) Figure 1 and Figure 2 As shown, this utility model discloses a light source device for detection.

[0027] The detection light source device includes: a horizontally mounted mounting plate 1, a light source assembly 2 arranged obliquely on the mounting plate 1, a heat dissipation mechanism 3 arranged below the mounting plate 1, and an air blowing device 4 arranged below the heat dissipation mechanism 3.

[0028] In this design, adjacent light source components 2 are staggered and dispersed on the mounting plate 1, resulting in uniform light distribution. The light source components 2 are tilted, allowing for concentrated light illumination from the relatively tilted components, thus improving the illumination brightness of the detection light source device. Furthermore, the light emitted by the light source components 2 is not linear, resulting in softer light.

[0029] The upper end of the mounting plate 1 is covered with a light-transmitting layer, and the light generated by the opposite light source component 2 is concentrated and shines on the screen after passing through the light-transmitting layer.

[0030] The light source components 2 are arranged at a high density and are tilted, which makes the heat generated by the light source components 2 more concentrated. The heat of the light source components 2 is transferred to the mounting plate 1, and the air blowing device 4 blows gas into the heat dissipation mechanism 3. The gas carries the heat of the light source components 2 out of the heat dissipation mechanism 3.

[0031] For example, the air blowing device 4 is a fan. The heat dissipation mechanism 3 is bent and connected to the air blowing end of the air blowing device 4. The gas generated by the air blowing device 4 flows to the bent position of the heat dissipation mechanism 3 and impacts it. After the gas diffuses, it flows, which improves the heat dissipation range of the heat dissipation mechanism 3.

[0032] Mounting strips 11 are arranged side by side on the mounting plate 1. The mounting strips 11 are arranged in a front-to-back direction and side by side in a left-to-right direction. Inclined surfaces 12 are formed on the mounting strips 11 at opposite angles. The inclined surfaces 12 are located on the left and right sides of the mounting strips 11, making the cross-section of the mounting strips 11 approximately trapezoidal. The inclined surfaces 12 of the mounting strips 11 allow the light source assembly 2 to be set at an angle.

[0033] The light source components 2 are staggered on the inclined surfaces 12 on both sides of the mounting strip 11. For example, the light source component 2 is a light strip. The LEDs on the light source component 2 are staggered on the opposing inclined surfaces 12. When installing the light source component 2, moving it forward or backward completes the staggered distribution of the light source components 2 on the mounting strip 11. Since the light source components 2 on adjacent mounting strips 11 are oppositely distributed, the light emitted by the light source components 2 on adjacent mounting strips 11 can be concentrated before illumination, improving the illumination brightness of the detection light source device.

[0034] A flow guide groove 13 is formed on the bottom surface of the mounting plate 1 near the mounting strip 11. Along the gas flow direction, the depth of the flow guide groove 13 gradually decreases from the middle to both sides.

[0035] The guide channel 13 is formed in the front-to-back direction on the bottom surface of the mounting plate 1 near the mounting strip 11. The cross-section of the guide channel 13 is approximately triangular. Since the heat dissipation mechanism 3 is positioned in the left-to-right direction at the lower end of the mounting plate 1, the gas generated by the air blowing device 4 flows in the left-to-right direction below the mounting plate 1. The heat generated by the light source assembly 2 is sequentially transferred to the mounting strip 11 and the mounting plate 1. When the gas generated by the air blowing device 4 flows along the heat dissipation mechanism 3, it enters the guide channel 13, and the gas carries away the heat from the mounting plate 1 within the guide channel 13.

[0036] The heat dissipation mechanism 3 includes a main body 31 and a diffuser 32 connected to each other. The diffuser 32 is bent and connected to the left end of the main body 31. A first channel 33 is formed in the left-right direction on the upper surface of the main body 31, and a second channel 34 is formed inside the diffuser 32. The first channel 33 is connected to the guide groove 13. The second channel 34 is connected to the first channel 33 and the air blowing end of the air blowing device 4.

[0037] The width of the second channel 34 gradually increases along the gas flow direction. One set of second channels 34 corresponds to multiple sets of first channels 33.

[0038] The air blowing device 4 generates gas, which flows along the second channel 34 on the left. As the width of the second channel 34 gradually increases, the gas gradually diffuses into each of the first channels 33. During its flow along the first channel 33, the gas enters the guide groove 13, carrying away the heat from the mounting plate 1 within the guide groove 13. The gas then flows out from the right end of the first channel 33. To ensure the stable placement of the mounting plate 1, a support foot is provided on the right end of the lower surface of the mounting plate 1.

[0039] The light source assembly 2 is mounted via the fixing assembly 5. The fixing assembly 5 includes a fixing bracket 51 and a fixing member 52. The fixing member 52 passes through the upper end of the fixing bracket 51 and is threaded to the upper end of the mounting strip 11. After tightening the fixing member 52, the fixing member 52 exerts downward pressure on the fixing bracket 51, and the fixing bracket 51 presses the light source assembly 2 firmly onto the mounting strip 11. Simply loosening the fixing member 52 allows the fixing bracket 51 to loosen, enabling adjustment of the front-to-back position of the light source assembly 2 or direct removal and reinstallation of the light source assembly 2.

[0040] The fixed bracket 51 includes a connecting piece 53 and elastic pieces 54 connecting the left and right sides of the connecting piece 53. After tightening the fixing piece 52, the elastic pieces 54 press against the light source assembly 2.

[0041] The connecting piece 53 is horizontally positioned in the left-right direction. The upper end of the elastic piece 54 is connected to the connecting piece 53. The elastic piece 54 protrudes and bends towards the light source assembly 2. The fixing bracket 51 is placed on the mounting strip 11, and the fixing member 52 passes through the connecting piece 53. At this time, the elastic piece 54 contacts the light source assembly 2. After tightening the fixing member 52, the elastic piece 54 elastically presses the light source assembly 2. The elastic piece 54 can continuously form elastic pressure on the light source assembly 2, preventing the light source assembly 2 from loosening.

[0042] Second embodiment:

[0043] Figure 3 A schematic diagram of the detection light source device according to the second embodiment of this utility model is shown. (Combined with...) Figures 1-3 As shown, the detection light source device also includes an air extraction device 6. The heat dissipation mechanism 3 is bent and connected to the air extraction end of the air extraction device 6. The air extraction device 6 extracts gas from the heat dissipation mechanism 3 and blows it in. For example, the air extraction device 6 is a fan.

[0044] Gas is drawn out of the heat dissipation mechanism 3 by the air extraction device 6 and blown in, which increases the flow rate of the gas in the heat dissipation mechanism 3 and allows the heat generated by the light source component 2 to be quickly discharged.

[0045] The diffuser 32 is bent and connected to the left and right ends of the main body 31. The blowing device 4 generates gas, which is extracted by the suction device 6. A negative pressure is formed in the gas in the second channel 34 on the other side. The gas flows along the second channel 34 on one side. As the width of the second channel 34 gradually increases, the gas gradually diffuses into each of the first channels 33. During the flow of the gas along the first channel 33, it enters the guide groove 13. The gas carries away the heat of the mounting plate 1 in the guide groove 13. After the gas enters the second channel 34 on the other side, the gas flows out through the blowing device 4.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
