Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a fluorescent host and its light source module. Background Technology

[0002] Currently, endoscopic systems are used in routine surgical procedures or internal medicine examinations. An endoscopic system includes a fluorescence main unit, which contains a light source module. The light source module includes a visible light source and a fluorescent light source. The visible light source can be configured to emit white light, and the fluorescent light source can be configured to emit infrared laser light. However, white light and infrared laser light consume relatively high power, resulting in significant heat generation from the visible light and fluorescent light sources.

[0003] In related technologies, visible light sources and fluorescent light sources use the same heat sink for heat dissipation. However, this can cause thermal interference between the visible light source and the fluorescent light source. Specifically, the heat emitted by the visible light source is directly transferred to the fluorescent light source through the heat sink, causing the temperature of the fluorescent light source to rise. Consequently, the light emitted by the fluorescent light source is deflected and cannot reach the target area. Summary of the Invention

[0004] The purpose of this application is to provide a fluorescent host and its light source module that can reduce or even avoid the thermal interference of heat generated by visible light sources on fluorescent light sources.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a light source module for a fluorescent host, including a light guide, a fluorescent light source, a visible light source, a first heat dissipation component, and a second heat dissipation component. The first heat dissipation component includes a first heat sink and a first cooling fan, and the second heat dissipation component includes a second heat sink and a second cooling fan.

[0007] The light guide has a first light inlet and a second light inlet spaced apart. A fluorescent light source is positioned facing the first light inlet, and a visible light source is positioned facing the second light inlet. Both a first heat sink and a second heat sink are connected to the light guide, and the first heat sink and the second heat sink are spaced apart.

[0008] The first heat sink is positioned opposite to the fluorescent light source, and the first heat sink is positioned opposite to the first cooling fan. A first heat transfer channel is provided between the first heat sink and the fluorescent light source, and also between the first cooling fan and the first heat sink.

[0009] The second heat sink is positioned opposite to the visible light source, and the second heat sink is positioned opposite to the second cooling fan. There are second heat transfer channels between the second heat sink and the visible light source, as well as between the second cooling fan and the second heat sink.

[0010] Secondly, this application also provides a fluorescent host, including a housing and the aforementioned light source module, wherein the light source module is disposed inside the housing, and the housing has an air inlet and an air outlet.

[0011] In this embodiment, a first heat transfer channel exists between the fluorescent light source and the first heat sink, and between the first heat sink and the first cooling fan. Therefore, the first cooling fan can dissipate heat for the fluorescent light source through these two first heat transfer channels. Similarly, a second heat transfer channel exists between the visible light source and the second heat sink, and between the second heat sink and the second cooling fan. Therefore, the second cooling fan can dissipate heat for the visible light source through these two second heat transfer channels. Thus, this application uses the first and second heat sinks to dissipate heat for the fluorescent and visible light sources respectively. The first and second heat sinks are spaced apart, meaning they are two separate components. Therefore, the heat emitted by the visible light source, after being transferred to the second heat sink, cannot be directly transferred to the first heat sink, thereby reducing or even avoiding thermal interference from the visible light source to the fluorescent light source.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The fluorescent host and its light source module provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] like Figures 1 to 8 As shown in the illustration, this application discloses a light source module for a fluorescent host, including a light guide 100, a fluorescent light source 200, a visible light source 300, a first heat dissipation component 400, and a second heat dissipation component 500. The first heat dissipation component 400 includes a first heat sink 410 and a first cooling fan 420, and the second heat dissipation component 500 includes a second heat sink 510 and a second cooling fan 520. Optionally, the visible light source 300 can be a white light source, and the fluorescent light source 200 can be an infrared light source; both the first cooling fan 420 and the second cooling fan 520 can be axial fans.

[0032] The light guide 100 has a first light inlet 110 and a second light inlet spaced apart. A fluorescent light source 200 faces the first light inlet 110, and a visible light source 300 faces the second light inlet. A first heat sink 410 and a second heat sink 510 are both connected to the light guide 100, and are spaced apart. Specifically, the light guide 100 also has a light outlet 120. The light guide 100 guides the light emitted by the fluorescent light source 200 from the first light inlet 110 to the light outlet 120, and guides the light emitted by the visible light source 300 from the second light inlet to the light outlet 120. The first light inlet 110 and the second light inlet can be located on the same side of the light guide 100, or on different sides of the light guide 100.

[0033] The first heat sink 410 is disposed opposite to the fluorescent light source 200, and the first heat sink 410 is disposed opposite to the first cooling fan 420. That is, at least a portion of the first heat sink 410 is disposed opposite to at least a portion of the fluorescent light source 200, and at least a portion of the first heat sink 410 is disposed opposite to at least a portion of the first cooling fan 420. There are first heat transfer channels between the first heat sink 410 and the fluorescent light source 200, and between the first cooling fan 420 and the first heat sink 410. Specifically, the fluorescent light source 200 can be connected to the first heat sink 410, and the part where they are connected is the first heat transfer channel, through which the heat generated by the fluorescent light source 200 can be transferred to the first heat sink 410 by thermal conduction; or, the fluorescent light source 200 can be disposed adjacent to the first heat sink 410, in which case there is a small first gap between the fluorescent light source 200 and the first heat sink 410, which is the first heat transfer channel, through which the heat generated by the fluorescent light source 200 can be transferred to the first heat sink 410 by thermal radiation. The first heat sink 410 can be connected to the first cooling fan 420, and the part where the two are connected is the first heat transfer channel. The heat on the first heat sink 410 can be transferred to the first cooling fan 420 by heat conduction. Alternatively, the first heat sink 410 can also be set adjacent to the first cooling fan 420. In this case, there is a small second gap between the first heat sink 410 and the first cooling fan 420. This second gap is the first heat transfer channel, and the heat on the first heat sink 410 can be transferred to the first cooling fan 420 by heat radiation.

[0034] The second heat sink 510 is disposed opposite to the visible light source 300, and the second heat sink 510 is disposed opposite to the second cooling fan 520. A second heat transfer channel exists between the second heat sink 510 and the visible light source 300, and between the second cooling fan 520 and the second heat sink 510. Specifically, the visible light source 300 can be connected to the second heat sink 510, and the connection point constitutes the second heat transfer channel; alternatively, the visible light source 300 can be disposed adjacent to the second heat sink 510, in which case a small third gap exists between the visible light source 300 and the second heat sink 510, and this third gap also constitutes the second heat transfer channel. The second heat sink 510 can be connected to the second cooling fan 520, and the connection point constitutes the second heat transfer channel; alternatively, the second heat sink 510 can be disposed adjacent to the second cooling fan 520, in which case a small fourth gap exists between the second heat sink 510 and the second cooling fan 520, and this fourth gap also constitutes the second heat transfer channel.

[0035] In this embodiment, a first heat transfer channel is provided between the fluorescent light source 200 and the first heat sink 410, and between the first heat sink 410 and the first cooling fan 420. Therefore, the first cooling fan 420 can dissipate heat for the fluorescent light source 200 through the two first heat transfer channels. A second heat transfer channel is provided between the visible light source 300 and the second heat sink 510, and between the second heat sink 510 and the second cooling fan 520. Therefore, the second cooling fan 520 can dissipate heat for the visible light source 300 through the two second heat transfer channels. Therefore, it can be seen that the present application uses the first heat sink 410 and the second heat sink 510 to dissipate heat from the fluorescent light source 200 and the visible light source 300, respectively. The first heat sink 410 and the second heat sink 510 are arranged alternately, that is, the first heat sink 410 and the second heat sink 510 are two separate components. Therefore, the heat emitted by the visible light source 300 is transferred to the second heat sink 510 and cannot be directly transferred to the first heat sink 410. Thus, the heat generated by the visible light source 300 is reduced or even avoided from causing thermal interference to the fluorescent light source 200.

[0036] In one optional embodiment, the first heat dissipation component 400 and the second heat dissipation component 500 are respectively located on adjacent sides of the light guide 100, and the first end of the second heat sink 510 extends along the direction near the side of the light guide 100 where the first heat dissipation component 400 is located. In this embodiment, the first heat dissipation component 400 and the second heat dissipation component 500 are respectively located on adjacent sides of the light guide 100. This allows the first heat sink 410 and the second heat sink 510 to be located on adjacent sides of the light guide 100. Compared to the first heat sink 410 and the second heat sink 510 being located on the same side of the light guide 100, this embodiment allows both the first heat sink 410 and the second heat sink 510 to have a longer extension space. For example, the first end of the second heat sink 510 extends along the direction near the side of the light guide 100 where the first heat dissipation component 400 is located. This increases the length of the second heat sink 510, thereby increasing the heat dissipation area of ​​the second heat sink 510 and improving the heat dissipation effect.

[0037] In one alternative embodiment, please refer to Figure 1-3 The second cooling fan 520 is positioned opposite to the second end of the second heat sink 510. Optionally, with Figure 1Taking the orientation shown as an example, the second cooling fan 520 can be located on the side of the second heat sink 510 away from the visible light source 300, that is, on the right side of the second heat sink 510, or it can be located on the upper side, lower side, or front side of the second heat sink 510. In this embodiment, since the first end of the second cooling fan 520 is located close to the first heat dissipation component 400, the second cooling fan 520 is positioned opposite to the second end of the second heat sink 510, which allows the second cooling fan 520 to be located away from the first heat sink 410 of the first heat dissipation component 400. This prevents the second cooling fan 520 from carrying away some of the heat from the second heat sink 510 and then transferring it to the first heat sink 410, thereby preventing this heat from causing thermal interference to the fluorescent light source 200. Of course, the second cooling fan 520 can also be positioned opposite to the first end of the second heat sink 510. This application does not limit the positional relationship between the second cooling fan 520 and the second heat sink 510.

[0038] In one alternative embodiment, please refer to Figure 4-7 The light guide 100 includes a main body 130 and a protrusion 140. The first heat dissipation component 400 and the second heat dissipation component 500 are respectively located on adjacent sides of the main body 130. The protrusion 140 and the first heat dissipation component 400 are located on the same side of the main body 130. A mounting groove 150 is formed between the protrusion 140 and the main body 130. At least a portion of the first heat dissipation component 400 is disposed in the mounting groove 150. The end faces of the second heat dissipation fan 520 and the first end of the second heat sink 510 are disposed opposite each other. The protrusion 140 is located between the second heat dissipation fan 520 and the first heat dissipation component 400. In this embodiment, a mounting groove 150 is formed between the protrusion 140 and the main body 130. At least a portion of the first heat dissipation component 400 is located within the mounting groove 150. This allows a portion of the first heat dissipation component 400 to be disposed inside the light guide 100, thereby reducing the volume of the light source module and the space occupied by the first heat dissipation component 400 outside the light guide 100. Furthermore, the protrusion 140 is located between the second heat dissipation fan 520 and the first heat dissipation component 400. Therefore, the protrusion 140 can block the heat carried away by the second heat dissipation fan 520 from the second heat sink 510 from being transferred to the first heat sink 410, thus preventing this heat from causing thermal interference to the fluorescent light source 200. It can be seen that this embodiment, while forming the mounting groove 150 to reduce the size of the light source module, also forms the protrusion 140 to prevent the heat carried away by the second heat dissipation fan 520 from the second heat sink 510 from being transferred to the first heat sink 410, thus achieving multiple technical effects from a single structure.

[0039] Furthermore, a mounting plate 511 is provided on the end face of the second heat sink 510. The mounting plate 511 extends along the side near the light guide 100 where the first heat dissipation component 400 is located. The mounting plate 511 is located between the second cooling fan 520 and the first heat dissipation component 400, and the second cooling fan 520 is connected to the mounting plate 511. In this embodiment, the mounting plate 511 can provide a mounting base for the second cooling fan 520, so that the second cooling fan 520 can be connected to the end face of both the mounting plate 511 and the second heat sink 510 at the same time. This can increase the mounting area of ​​the second cooling fan 520 and the second heat sink 510, thereby improving the connection strength between the second cooling fan 520 and the second heat sink 510. In addition, the mounting plate 511 is located between the second cooling fan 520 and the first heat dissipation component 400, so that the mounting plate 511 and the protrusion 140 can jointly block the heat carried away by the second cooling fan 520 from the second heat sink 510 from being transferred to the first heat sink 410. Furthermore, the mounting plate 511 is a heat-insulating structural component, which can further prevent the heat carried away by the second cooling fan 520 from the second heat sink 510 from being transferred to the first heat sink 410, so as to prevent this part of the heat from causing thermal interference to the fluorescent light source 200.

[0040] In one optional embodiment, the protrusion 140 is a heat-insulating structural component. In this embodiment, the protrusion 140, as a heat-insulating structural component, can further prevent the heat carried away by the second cooling fan 520 from the second heat sink 510 from being transferred to the first heat sink 410, thereby preventing this heat from causing thermal interference to the fluorescent light source 200. Of course, the protrusion 140 can also be a heat-conducting structural component, and this application does not limit the material of the protrusion 140.

[0041] The fluorescent light source 200 is highly sensitive to temperature. To prevent a large temperature rise in the fluorescent light source 200, in one optional embodiment, please refer to... Figure 2 , 6 8. The first heat dissipation component 400 further includes a cooling plate 430, which has a cold side and a hot side. The cold side is in contact with the fluorescent light source 200, and the hot side is in contact with the first heat sink 410. In this embodiment, the cold side of the cooling plate 430 is in contact with the fluorescent light source 200, which can cool the fluorescent light source 200 and prevent it from generating a large temperature rise. The heat generated by the hot side can be released through the first heat sink 410 and the first cooling fan 420. Optionally, thermally conductive interface materials such as thermally conductive grease can be selectively filled between the cooling plate 430 and the fluorescent light source 200, between the cooling plate 430 and the first heat sink 410, and between the visible light source 300 and the second heat sink 510 to increase heat transfer efficiency.

[0042] To prevent heat released by the first heat sink 410 and the first cooling fan 420 from flowing back to the cooling chip 430 and the fluorescent light source 200 and causing condensation, in an optional embodiment, the light source module further includes an annular heat insulation pad 600. The fluorescent light source 200 is disposed inside the light guide 100 through the first light inlet 110. The annular heat insulation pad 600 is sealed between the first heat sink 410 and the end face of the light guide 100 adjacent to the first light inlet 110, and the annular heat insulation pad 600 surrounds the outside of the cooling chip 430. In this embodiment, the annular heat insulation pad 600 is sealed between the first heat sink 410 and the end face of the light guide 100 adjacent to the first light inlet 110, and the annular heat insulation pad 600 surrounds the outside of the cooling chip 430. This can prevent the heat released by the first heat sink 410 and the first cooling fan 420 from entering through the gap between the first heat sink 410 and the light guide 100, and then coming into contact with the cooling chip 430 and the fluorescent light source 200 to produce condensation. In addition, the annular heat insulation pad 600 being sealed between the end face of the first heat sink 410 and the end face of the light guide 100 adjacent to the first light inlet 110 can also prevent dust or foreign objects other than the light source module from entering the light guide 100, and prevent light other than the light source module from entering the light guide through the gap between the two, thereby interfering with the propagation of visible light and fluorescence. As can be seen, after setting the annular heat insulation pad 600 in this embodiment, not only can the heat released by the first heat sink 410 and the first cooling fan 420 flow back to the cooling chip 430 to produce condensation, but it can also prevent dust, foreign objects and light from entering the light guide 100 outside the light source module, thereby achieving the purpose of multiple uses.

[0043] To further prevent condensation from forming on the cooling chip 430 and the fluorescent light source 200, in an optional embodiment, the light source module further includes a desiccant 700 disposed adjacent to the cooling chip 430. In this embodiment, the desiccant 700 is disposed adjacent to the cooling chip 430. Since the fluorescent light source 200 is stacked with the cooling chip 430, the desiccant 700 is also adjacent to the fluorescent light source 200. The desiccant 700 can remove moisture from the air near the fluorescent light source 200 and the cooling chip 430, thus further reducing the risk of condensation forming on the cooling chip 430 and the fluorescent light source 200.

[0044] The desiccant 700 can be disposed on the surface of the first heat sink 410 facing the cooling plate 430. When a large amount of desiccant 700 is required, the desiccant 700 may protrude from the fluorescent light source 200. In this case, the desiccant 700 will block some of the light emitted by the fluorescent light source 200 from reaching the light guide 100. In an optional embodiment, the surface of the first heat sink 410 facing the cooling plate 430 is provided with a groove 411, and the desiccant 700 is disposed in the groove 411. In this embodiment, the first heat sink 410 is provided with a groove 411. Since the groove 411 extends away from the fluorescent light source 200, after the desiccant 700 is disposed in the groove 411, the desiccant 700 can also extend along the direction of the groove 411. That is to say, the groove 411 can accommodate a large amount of desiccant 700. Therefore, after the groove 411 is provided, even when a large amount of desiccant 700 is required, the desiccant 700 will not protrude from the fluorescent light source 200, thus avoiding the desiccant 700 blocking the light emitted by the fluorescent light source 200.

[0045] In one optional embodiment, the first cooling fan 420 and the second cooling fan 520 are respectively oriented towards different sides of the light guide 100. The airflow direction of the first cooling fan 420 is towards the first heat sink 410, that is, the air outlet of the first cooling fan 420 faces the first heat sink 410. The airflow direction of the second cooling fan 520 is away from the second heat sink 510, that is, the air inlet of the second cooling fan 520 faces the second heat sink 510. In this embodiment, the airflow direction of the first cooling fan 420 is towards the first heat sink 410, at which time the first cooling fan 420 can deliver cool air from outside the light source module to the first heat sink 410, thereby cooling the first heat sink 410. The airflow direction of the second cooling fan 520 is away from the second heat sink 510, at which time the second cooling fan 520 can transfer heat from the second heat sink 510 to the outside of the light source module, thereby cooling the second heat sink 510. In addition, the first cooling fan 420 and the second cooling fan 520 are located on different sides of the guide member, so that the first cooling fan 420 and the second cooling fan 520 are far apart, and the second cooling fan 520 and the first heat sink 410 are far apart. This can prevent the heat discharged by the second cooling fan 520 from being transferred to the first heat sink 410, thereby causing thermal interference to the fluorescent light source 200.

[0046] Alternatively, the first cooling fan 420 and the second cooling fan 520 may face different sides of the light guide 100. The airflow direction of the first cooling fan 420 is away from the first heat sink 410, meaning that the air inlet of the first cooling fan 420 faces the first heat sink 410, and the airflow direction of the second cooling fan 520 is towards the second heat sink 510, meaning that the air outlet of the second cooling fan 520 faces the second heat sink 510. In this embodiment, the airflow direction of the first cooling fan 420 is away from the first heat sink 410, at which time the first cooling fan 420 can transfer the heat on the first heat sink 410 to the outside of the light source module, thereby cooling the first heat sink 410; the airflow direction of the second cooling fan 520 is towards the second heat sink 510, at which time the second cooling fan 520 can deliver cold air from outside the light source module to the second heat sink 510, thereby cooling the second heat sink 510. In addition, the first cooling fan 420 and the second cooling fan 520 are located on different sides of the guide member, so that the first cooling fan 420 and the second cooling fan 520 are far apart, and the second cooling fan 520 and the first heat sink 410 are far apart. This can prevent the heat discharged by the first cooling fan 420 from being transferred to the second heat sink 510, thereby causing thermal interference to the visible light source 300.

[0047] In one optional embodiment, both the first cooling fan 420 and the second cooling fan 520 face the same side of the light guide 100. The airflow direction of the first cooling fan 420 is towards the first heat sink 410, and the airflow direction of the second cooling fan 520 is towards the second heat sink 510. That is, the air outlet of the first cooling fan 420 faces the first heat sink 410, and the air outlet of the second cooling fan 520 faces the second heat sink 510. In this embodiment, the first cooling fan 420 can deliver cool air from outside the light source module to the first heat sink 410, thereby cooling the first heat sink 410. The second cooling fan 520 can deliver cool air from outside the light source module to the second heat sink 510, thereby cooling the second heat sink 510. In addition, since both the first cooling fan 420 and the second cooling fan 520 are located on the same side of the light guide, the amount of cool air drawn into the light source module can be increased, which is beneficial for cooling the light source module.

[0048] Alternatively, both the first cooling fan 420 and the second cooling fan 520 face the same side of the light guide 100, with the airflow direction of the first cooling fan 420 away from the first heat sink 410, and the airflow direction of the second cooling fan 520 away from the second heat sink 510. That is, the air inlet of the first cooling fan 420 faces the first heat sink 410, and the air inlet of the second cooling fan 520 faces the second heat sink 510. In this embodiment, the first cooling fan 420 can transfer heat from the first heat sink 410 to the outside of the light source module, thereby cooling the first heat sink 410. The second cooling fan 520 can transfer heat from the second heat sink 510 to the outside of the light source module, also cooling the second heat sink 510. Furthermore, since both the first cooling fan 420 and the second cooling fan 520 are located on the same side of the light guide, the amount of heat dissipated from the light source module to the external environment can be increased, thus facilitating the cooling of the light source module.

[0049] In an optional embodiment, the first cooling fan 420 is disposed opposite to the fluorescent light source 200. In this embodiment, the first cooling fan 420 is located on the side of the first heat sink 410 away from the fluorescent light source 200 and is disposed opposite to the fluorescent light source 200. This allows the first cooling fan 420 to be disposed close to the fluorescent light source 200, thereby improving the heat dissipation effect of the first cooling fan 420.

[0050] And / or, the second cooling fan 520 is disposed opposite to the visible light source 300. In this embodiment, the second cooling fan 520 is located on the side of the second heat sink 510 away from the visible light source 300 and is disposed opposite to the visible light source 300. This allows the second cooling fan 520 to be disposed close to the visible light source 300, thereby improving the heat dissipation effect of the second cooling fan 520.

[0051] like Figures 9 to 15 As shown in the illustration, this application also discloses a fluorescent host, including a housing 800 and a light source module as described in any of the above embodiments. The light source module is disposed within the housing 800, which has an air inlet 821 and an air outlet 811. This application uses a first heat sink 410 and a second heat sink 510 to dissipate heat from the fluorescent light source 200 and the visible light source 300, respectively. The first heat sink 410 and the second heat sink 510 are spaced apart, meaning they are two separate components. Therefore, the heat emitted by the visible light source 300 is transferred to the second heat sink 510 but cannot be directly transferred to the first heat sink 410, thus reducing or even avoiding thermal interference from the visible light source 300 to the fluorescent light source 200.

[0052] Optionally, the housing 800 includes a detachably connected housing body 810 and a top cover 820. The light source module is disposed on the housing body 810, and the housing body 810 is provided with an air outlet 811, while the top cover 820 is provided with an air inlet 821. Further, the housing body 810 is also provided with a main board 920, a power board 930, and a driver board 940. The main board 920 and the power board 930 are disposed near the air inlet 821, and the driver board 940 is disposed near the air outlet 811.

[0053] In one optional embodiment, the air inlet 821 and the air outlet 811 are located on two different sides of the housing 800, the first cooling fan 420 and the second cooling fan 520 are respectively facing different sides of the light guide 100, the airflow of the first cooling fan 420 is towards the first radiator 410, and the first cooling fan 420 is arranged opposite to the air inlet 821, and the airflow of the second cooling fan 520 is towards the air outlet 811. In this embodiment, the airflow of the first cooling fan 420 is directed toward the first radiator 410, and the first radiator 410 is opposite to the air inlet 821. The first radiator 410 is also opposite to the fluorescent light source 200. Therefore, the fluorescent light source 200 is located near the air inlet 821. In this way, the cold air entering from the air inlet 821 can reach the fluorescent light source 200 through a shorter path within the housing 800. The temperature rise of the cold air is smaller when it passes through the housing 800, so the temperature of the air when it reaches the fluorescent light source 200 is lower, thereby improving the cooling effect on the first radiator 410.

[0054] In an optional embodiment, the air inlet 821 and the air outlet 811 are located on different sides of the housing 800. The first cooling fan 420 and the second cooling fan 520 both face the same side of the light guide 100. The airflow direction of the first cooling fan 420 is towards the first heat sink 410, and the airflow direction of the second cooling fan 520 is towards the second heat sink 510. Both the first cooling fan 420 and the second cooling fan 520 are positioned opposite to the air inlet 821. In this embodiment, the first cooling fan 420 and the second cooling fan 520 are both located on the same side of the light guide, which increases the amount of cold air drawn into the housing 800 by the light source module, thereby facilitating the cooling of the light source module. Furthermore, the air outlet 811 is provided with a third cooling fan 910, which faces the outside of the housing 800, thus transferring heat from inside the housing 800 to the outside.

[0055] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
