[0035] As described in the background technology, each wavelength light source on the market is equipped with a power supply box to drive it, and multiple wavelength light sources require multiple boxes to be stacked. This solution technology produces light sources with large volume and many water channels, which increases the difficulty of environmental control and heat dissipation of LDI equipment and the difficulty of space layout.
[0036] Based on this, this application provides a laser device and system to overcome the above-mentioned technical problems.
[0037] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0038] Please refer to Figure 1 , Figure 1 A schematic diagram of the laser device in this embodiment is shown. The laser device 10 includes: a control module 101, a switching module 102, multiple laser source modules 103, and a power supply module 104.
[0039] The control module 101 is connected to the control terminal of the switching module 102; the switching module 102 includes multiple output channels 102A; the input terminal of the switching module 102 is connected to the power supply module 104, and each output channel 102A is connected to a laser source module 103; the power supply module 104 is connected to the corresponding laser source module 103 through the output channel 102A, forming a laser link.
[0040] In this embodiment, the laser device 10 includes multiple operating states. For any operating state, the control module 101 sends a control signal to the control terminal of the switching module 102 to activate the laser link corresponding to the preset laser wavelength in the current operating state.
[0041] It should be noted that, please refer to Figure 2 , Figure 2 This illustration shows another structural diagram of the laser device in this embodiment. Each laser source module 103 in this embodiment includes multiple laser units 201; and the laser units 201 under the multiple laser source modules 103 are arranged in an L-shape. This embodiment, through the L-shaped loop arrangement, allows for the arrangement of more light source devices within the same volume. The laser device in this embodiment includes left and right L-shaped structures, wherein both left and right L-shaped structures are formed by the arrangement of laser units 201, and the left and right L-shaped structures are connected by a water pipe with an inner diameter of 8.5 mm.
[0042] Based on this, this application improves the control efficiency of existing LDI devices and enhances device adaptability by integrating multiple laser units with different laser wavelengths and adjusting the conduction or cutoff of the laser link according to user needs through a control module. At the same time, by arranging the light source devices in an L-shape, the spatial layout difficulty and environmental control and heat dissipation difficulty of existing LDI devices are reduced.
[0043] To further improve the heat dissipation efficiency of the device, please refer to... Figure 3 , Figure 3 Another schematic diagram of the laser device in this embodiment is shown. In this embodiment, the laser device 10 further includes a heat dissipation module 105, which includes multiple heat dissipation channels 202 arranged in an L-shaped loop along the arrangement path of the multiple laser light source modules. This embodiment achieves increased heat dissipation performance while saving device size by maintaining the same arrangement of the heat dissipation channels as the light source devices.
[0044] In one possible implementation, this embodiment achieves efficient heat dissipation through multiple water-cooling channels. Specifically, please refer to... Figure 2 Based on this, continue to refer to Figure 3 This cooling water system comprises three layers and two layers of water channels, which can alternate to increase flow rate and improve heat dissipation. Taking the L-shaped structure on the left as an example, the long side of this structure contains the aforementioned three-layer water channels, while the short side contains the aforementioned two-layer water channels. Initially, the water flows through the three-layer water channels. Upon entering the L-shaped bend, the water flows together and then through a water trough to the two-layer water channels. Please continue to refer to... Figure 2Because the left and right L-shaped structures are connected by a water pipe with an inner diameter of 8.5mm, water flows out from the two layers of water channels and then through the aforementioned water pipe to the right L-shaped structure, entering the two auxiliary water channels within the right L-shaped structures. Finally, it flows out through the three layers of water channels within the right L-shaped structures, achieving the purpose of cooling.
[0045] Please refer to Figure 4 , Figure 4 Another schematic diagram of the laser device in this embodiment is shown. In this embodiment, the laser device 10 further includes an amplifier module 106; the amplifier module 106 is connected to the output terminal of the power supply module 104 and the input terminal of the switching module 102, respectively. In this embodiment, the power supply provided by the power supply module 104 can be converted into a preset voltage of the switching module 102 through the amplifier module 106, thereby improving the power adaptability of the laser device.
[0046] Please refer to Figure 5 , Figure 5 The diagram shows the structure of the switching module in this embodiment. The switching module 102 in this embodiment includes multiple coded switches 203. Each output terminal of the coded switch 203 (i.e., the above-mentioned output channel 102A) is connected to a laser source module 103. The control terminal of the coded switch 203 is connected to the control module 101.
[0047] In one possible implementation, when the laser device 10 includes 25 DIP switches, the switching module 102 includes 45 laser links; each laser link can simultaneously power four laser units 201, in which case the multiple laser source modules 103 can include 180 laser units 201. In this embodiment, the 45 laser links are controlled by 25 DIP switches. Specifically, 21 DIP switches can individually control two laser links, and the remaining 3 DIP switches can individually control one laser link.
[0048] In this embodiment, different or the same area can be controlled by different encoding switches 203.
[0049] In one possible implementation, taking the control of the same area by different coding switches 203 as an example, when each laser source module 103 includes a laser wavelength and the area where multiple laser source modules 103 are located is divided by the same laser wavelength, then, for any working state, the control module 101 is used to send control signals to the control terminals of each coding switch 203 in the corresponding area to turn on each laser link in the current area.
[0050] The output voltage of each output channel 102A is the same.
[0051] For example, assuming that both DIP switch 1 and DIP switch 2 modulate region A, and the laser wavelength corresponding to region A is 405nm, then all four laser links controlled by DIP switch 1 and DIP switch 2 can be set to laser units with a laser wavelength of 405nm; assuming that both DIP switch 3 and DIP switch 4 modulate region B, and the laser wavelength corresponding to region B is 395nm, then all four laser links controlled by DIP switch 3 and DIP switch 4 can be set to laser units with a laser wavelength of 395nm.
[0052] In one possible implementation, in this embodiment, the control module 101 is a host computer. Correspondingly, the host computer's software interface can be set with switch control buttons for four zones, A, B, C, and D (each zone corresponds to a different laser wavelength). If a laser source with a wavelength of 405nm is required, zone A can be opened through the host computer. At this time, the target DIP switch with the same laser wavelength as zone A is turned on.
[0053] Simultaneously, the control module 101 also sends control signals to the power supply module 104 to set the power supply parameters according to the power supply requirements of the laser source installed in area A, that is, to adjust the output voltage of each output channel 102A under the corresponding switching module 102. In this embodiment, since each DIP switch is equipped with a laser unit 201 with the same laser wavelength, the output voltage of each output channel 102A is the same.
[0054] Based on this, this embodiment can use the control module 101 to control the laser unit 201 in the corresponding laser link to emit light when the DIP switch 1 and DIP switch 2 are switched to region A.
[0055] Following the same approach as the previous embodiment, if the host computer simultaneously opens four regions A, B, C, and D, the laser unit 201 in the corresponding four regions will emit light simultaneously, thereby achieving the simultaneous emission of multiple wavelengths.
[0056] In another possible implementation, when each laser source module 103 includes multiple different laser wavelengths, for any operating state, the control module 101 sends a control signal to the control terminal of each coded switch 203 to activate the laser link corresponding to the preset laser wavelength in the current operating state.
[0057] Since the DIP switch has four positions: A, B, C, and D, DIP switch 1 can be set to four laser modules with different laser wavelengths. For example, the laser wavelength corresponding to area A is 405nm, and the laser wavelength corresponding to area B is 395nm. At this time, the output terminal of DIP switch 1 at position A can be set to laser unit 201 with a laser wavelength of 405nm, the output terminal of DIP switch 1 at position B can be set to laser unit 201 with a laser wavelength of 395nm, and so on.
[0058] In this embodiment, the control module 101 is a host computer. Correspondingly, four switch control buttons (A, B, C, and D, corresponding to different laser wavelengths) can be set on the host computer's software interface. If a laser source with a wavelength of 405nm is needed, the host computer can open area A. At this time, the host computer sends a control signal to the control terminal of each coded switch 203 to switch each coded switch 203 to position A, thereby turning on the laser unit 201 with a laser wavelength of 405nm. If a laser source with a wavelength of 395nm is needed, the host computer can open area B. At this time, a control signal is sent to the control terminal of each coded switch 203 to switch each coded switch 203 to position B, thereby turning on the laser unit 201 with a laser wavelength of 395nm.
[0059] At the same time, the control module 101 will also send a control signal to the power supply module 104 to set the power supply parameters according to the power supply requirements of the laser light source installed in area A, that is, to adjust the output voltage of each output channel 102A under the corresponding switching module 102.
[0060] Following the same approach as the previous embodiment, if the host computer simultaneously opens four regions A, B, C, and D, the laser unit 201 in the corresponding four regions will emit light simultaneously, thereby achieving the simultaneous emission of multiple wavelengths.
[0061] Based on this, this embodiment can add more zones on the circuit board by using DIP switches according to the laser wavelength type of the laser unit 201, so as to realize the circuit board zone power control and the integration of multiple laser units 201 with different laser wavelengths.
