[0033] As described in the background, the multiple light source excitation blocks of the multi-channel fluorescence imaging device on the market either use the same light source or need to be externally connected with a separate light source. When using the same light source, the light source needs to be moved and connected with different light source excitation blocks in the actual use process. The light source and the light source excitation block are misaligned or have a long connection time. When the multiple light source excitation blocks are externally connected with a separate light source, the light source needs to be installed one by one and connected with the light source excitation block. The operation process is time-consuming, and the repeated disassembly and assembly operation affects the connection accuracy. Whether the multiple light source excitation blocks use the same light source or the multiple light source excitation blocks need to be externally connected with a separate light source, the convenience and stability of the imaging device during use are affected.

[0034] Based on the above problems, the embodiments of the present application provide a multi-channel light source device which can solve the above problems. Next, it will be described in detail.

[0035] Please refer to Figure 1 With Figure 2 The multi-channel light source device includes a shell, multiple light source excitation blocks 2 and multiple light source modules 3. The multiple light source excitation blocks 2 are installed in the interior of the shell at intervals. The multiple light source modules 3 correspond to the multiple light source excitation blocks 2 one by one and are connected respectively. The multiple light source modules 3 are installed in the shell.

[0036] The multi-channel light source device of the present embodiment adopts the mode that each light source excitation block 2 is equipped with a light source module 3, avoids the mode that multiple light source excitation blocks 2 share a light source, and does not need to externally connect a light source to the multiple light source excitation blocks 2. The problem that the repeated disassembly and assembly operation affects the connection accuracy when the multiple light source excitation blocks 2 are externally connected with a separate light source is solved. The problem that the light source module 3 and the light source excitation block 2 are misaligned or have a long connection time is solved. The stability of imaging and the convenience of using the device are improved.

[0037] The plurality of light source modules 3 can be installed inside the outer shell or outside the outer shell. In this embodiment, the plurality of light source modules 3 are installed inside the outer shell to increase the aesthetic appearance and regularity of the overall device.

[0038] The outer shell of this embodiment includes a bottom plate 10, a top plate 11, a left side plate 12, a right side plate 13, a front side plate 14, and a rear side plate 15. The top plate 11 and the rear side plate 15 are integrally formed. The bottom plate 10, the left side plate 12, the right side plate 13, and the front side plate 14 are rectangular plates. The bottom plate 10, the top plate 11, the left side plate 12, the right side plate 13, the front side plate 14, and the rear side plate 15 are connected together to form a rectangular box. The rectangular box is hollow inside to accommodate the light source excitation block 2 and the light source module 3. The connection between the bottom plate 10, the top plate 11, the left side plate 12, the right side plate 13, the front side plate 14, and the rear side plate 15 can include various connection methods, such as screws, bolts, hinges, locks, etc. In this embodiment, the connection is by screws.

[0039] The light source module 3 is used to generate light. The generated light passes through the main light path of the light source excitation block 2 and then excites the light generated by the light source module 3 into light that meets the requirements through the light source excitation block 2. The light source module 3 provides sufficient energy for light generation. The light source module 3 is a prior art, and its specific structure and working principle are not described here.

[0040] The light source excitation block 2 includes an excitation block rear cover 20, an excitation block front cover 21, and a dichroic mirror 22. The excitation block rear cover 20 and the excitation block front cover 21 are detachable. The dichroic mirror 22 is disposed between the excitation block rear cover 20 and the excitation block front cover 21 and is tightly fixed by the excitation block front cover 21 and the excitation block rear cover 20.

[0041] Specifically, the excitation block rear cover 20 and the excitation block front cover 21 have inclined surfaces that are each at a 45° angle to the horizontal direction. The dichroic mirror 22 is clamped and fixed between the inclined surfaces of the excitation block rear cover 20 and the excitation block front cover 21, and the dichroic mirror 22 is also arranged at a 45° angle to the horizontal. The dichroic mirror 22 can be used to reflect and transmit light of a certain range of wavelengths generated by the light source module 3, thereby separating out the desired target wavelength of light. The connection between the excitation block front cover 21 and the excitation block rear cover 20 is not limited, such as magnetic connection or screw connection. However, regardless of the detachable or fixed connection method, it cannot damage or affect the dichroic mirror 22.

[0042] The excitation block front cover 21 is provided with a main light path channel, the axial direction of the main light path channel is horizontal and coaxial with the light source module 3. The excitation block front cover 21 is provided with an emission hole, the axial direction of the emission hole is perpendicular to the main light path channel, when the light generated by the light source module 3 passes through the main light path channel and is irradiated on the dichroic mirror 22, the dichroic mirror 22 reflects the light of the target wavelength, and the reflected light of the target wavelength is emitted from the emission hole, and the light of the non-target wavelength is transmitted from the dichroic mirror 22.

[0043] The top plate 11 of the outer shell is provided with a light outlet 111, and the emission hole can be aligned with the light outlet 111, so that the light of the target wavelength is emitted and utilized.

[0044] The light outlet 111 can also be covered with a filter, which further filters the light of the non-target wavelength to obtain light of the target wavelength with higher purity. The filter and the top plate 11 are movably connected, so that different filters can be replaced conveniently; one implementation is that the light outlet 111 is a stepped hole, the side of the stepped hole close to the outer surface of the top plate 11 is a large-diameter end, and the side close to the inner wall surface of the top plate 11 is a small-diameter end, the size and shape of the filter are matched with the large-diameter end of the stepped hole, so that the filter can be placed in the stepped hole to avoid displacement of the filter. Of course, the position of the stepped hole corresponds to the position of the emission hole on the light source excitation block 2, and the light emitted from the emission hole can pass through the stepped hole.

[0045] Since the multi-channel light source device includes a plurality of light source modules 3, each light source module 3 can generate light within a certain wavelength range, and different light source modules 3 generate light with different wavelength ranges, so that different wavelengths of light can be utilized during use. The inner part of the outer shell is also provided with a switching piece 4, which switches the position of different light source excitation blocks 2, so that the emission holes of different light source excitation blocks 2 are aligned with the light outlet 111, thereby obtaining the required light of the target wavelength.

[0046] As an implementation, the switching piece 4 is a lead screw motor, the lead screw motor has a lead screw, a sliding cylinder is sleeved on the lead screw, the inner wall of the sliding cylinder is provided with a thread, and the sliding cylinder and the lead screw are threadedly rotatable; when the lead screw motor is started and works, the lead screw rotates, and since the lead screw itself only rotates without displacement, the sliding cylinder sleeved on the lead screw moves along the axial direction of the lead screw.

[0047] The light source installation block 40 is fixedly connected to the sliding cylinder, and the plurality of light source excitation blocks 2 are installed on the light source installation block 40. The sliding cylinder drives the light source installation block 40 to move, and then drives the light source excitation block 2 to move. In this embodiment, since the plurality of light source modules 3 are fixedly connected to the plurality of light source excitation blocks 2 respectively, the light source modules 3 can also be directly fixed on the light source installation block 40. The light source installation block 40 drives the light source modules 3 and the light source excitation blocks 2 to move simultaneously. The lead screw motor is installed on the left side plate 12. By controlling the working process of the lead screw motor, the emission holes of the different light source excitation blocks 2 can be aligned with the light outlet 111. For example, the lead screw motor is a step lead screw motor. The step length of the lead screw motor is recorded to obtain the displacement length of the sliding cylinder on the lead screw, and then it can be known whether the emission holes of the light source excitation blocks 2 are aligned with the light outlet 111.

[0048] In this embodiment, the controller 121 is further arranged on the left side plate 12. The controller 121 is in communication connection with the lead screw motor. The controller 121 controls the start-stop and working time length of the lead screw motor. The controller 121 can be programmed by using a PLC module to receive information and issue instructions. The specific model of the controller 121 can be selected by itself, and the programming part of the program can be easily realized by using the existing technology. Therefore, part of the controller 121 is regarded as the prior art.

[0049] In order to further facilitate operation and use, the outer wall surface of the front side plate 14 is further provided with an operation screen 141. The operation screen 141 is a touch screen. The operation screen 141 is in communication connection with the controller 121. By performing instruction operation on the operation screen 141, light with different wavelengths in different ranges can be selected. Of course, a plurality of buttons 142 can also be arranged on the operation screen 141. The plurality of buttons 142 correspond to the plurality of light source modules 3. By selecting light with a target wavelength through the plurality of buttons 142, the selected signal is transmitted to the controller 121. After signal processing, the controller 121 controls the lead screw motor to work and operate for a corresponding time length. The light source module 3 with the target wavelength can be located directly below the light outlet 111.

[0050] The inside of the shell body is further provided with a limit switch 101. The limit switch 101 is arranged on the bottom plate 10 and located at the side of the light source module 3. When the light source module 3 at the most side of the plurality of light source modules 3 is in contact with the limit switch 101, all the light source modules 3 are in the most initial position. Then, light with a target wavelength is selected through the operation screen 141 or the button 142, and the controller 121 controls the lead screw motor to work. The limit switch 101 can be a distance sensor for detecting the distance from the light source module 3. The distance sensor is in communication connection with the controller 121, so that the position of the light source module 3 can be accurately mastered.

[0051] Of course, the plurality of light source modules 3 can also be respectively connected with the controller 121 in communication, and the start and stop of the light source modules 3 in a certain part is controlled through the controller 121.

[0052] The right side plate 13 is further provided with a power socket 131 and a power switch 132, the lead screw motor, the controller 121, the light source module 3 in the inner housing, and the operation screen 141 and the button 142 outside the housing are respectively connected with the power socket 131 in electricity, and the power switch 132 can control the circuit on-off of the power socket 131.

[0053] The housing can be further provided with a plurality of heat dissipation holes, so as to facilitate the heat dissipation of the inner space of the housing.

[0054] The multi-channel light source device of the embodiment of the utility model improves the convenience of device use and the stability of imaging by equipping each light source excitation block 2 with a light source module 3.

[0055] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
