[0035] First embodiment

[0036] like Figures 1 to 4 As shown, a hybrid light source device includes an LED light source module 10 , a laser light source module 20 and a heat dissipation component 30 .

[0037] The LED light source module includes a housing 101 and a base plate 102 connected to the housing 101. The base plate 101 defines an opening 103, and the housing 101 and the base plate 102 form a receiving space. It is understood that in a preferred embodiment, the opening 103 is located in the center of the base plate 101. However, in some environments requiring special lighting effects, the opening 103 may also be located in a non-central area of ​​the base plate 101.

[0038] The LED light source module also includes a plurality of LED light-emitting chips 104 arranged on the base plate, and a collimating lens 105 arranged in the accommodating space and corresponding to the plurality of LED light-emitting chips 104 one by one. The collimating lens 105 is used to collect the output light of the LED light-emitting chip to improve the light utilization rate of the LED light-emitting chip. The LED light source module also includes a focusing lens 106 arranged at the light-emitting end of the shell, and the focusing lens 106 is used to converge the light beam emitted by the collimating lens 105.

[0039] Furthermore, an opening 103 is provided on the base plate 102, and the opening 103 is used to set the light emitting part of the laser light source module 20 mixed with the LED light source module. It should be noted that a collimating lens 105 is still provided on the light emitting optical path corresponding to the opening 103. This collimating lens 105 is used to collect the light emitted from the light emitting part of the laser light source module 20 set at the position of the opening 103, so that the LED light beam and the laser light beam collected by the collimating lens 105 maintain consistency in light effect, that is, the optical axes of the LED light beam and the laser light beam emitted by the collimating lens 105 are parallel and have the same divergence angle.

[0040] Furthermore, the light emitting portion of the laser light source module 20 arranged in the opening 103 is flush with the light emitting surface of the LED light-emitting chip, and an adjustment gap is left between the light emitting portion of the laser light source module 20 and the hole wall of the opening 103. The horizontal position of the light emitting portion of the laser light source module 20 in the opening is adjusted by external force or a screw assembly, that is, the position of the light emitting portion of the laser light source module 20 in the opening is adjusted so that the light spot emitted by the laser light source module is concentric with the light spot emitted by the LED light source module. At this time, the laser light source module and the LED light source module are sealed and fixed.

[0041] It should be noted that the alignment of the light emitting portion of the laser light source module 20 with the light emitting portion of the LED light emitting chip (i.e., vertical adjustment) is achieved through the precision machining of structural components.

[0042] Compared with the prior art, the present invention achieves an optical effect in which the laser light source module's output light spot is concentric with the LED light source module's light spot by making a two-dimensional horizontal adjustment of the laser light source module as a whole relative to the LED light source module, thereby further improving the optical effect of the hybrid light source device.

[0043] The heat dissipation assembly 30 is used to dissipate heat from the LED light source module 10 and to fix the laser light source module 20. That is, the heat dissipation assembly 30 mainly dissipates heat from the LED light source module, and only serves to support and fix the laser light source module. The heat dissipation assembly 30 includes a mounting plate and a heat dissipation portion, wherein an opening 301 is provided at a position corresponding to the bottom plate opening 103 of the LED light source module. It should be noted that the opening 301 of the mounting plate is not completely consistent in size with the bottom plate opening 103 of the LED light source module, and can be slightly larger than the size of the opening 103 to facilitate the assembly of the laser light source module 20. Furthermore, the heat dissipation assembly 30 also includes a positioning portion 3011 extending radially along the opening 301 of the mounting plate. The positioning portion 3011 is used to match the anti-foolproof part of the laser light source module when the laser light source module is installed to achieve a positioning function, thereby improving the installation efficiency of the laser light source module. Furthermore, the mounting plate of the heat dissipation assembly 30 is provided with a plurality of screw holes, and the base plate of the LED light source module is tightly connected to the mounting plate of the heat dissipation assembly by screw locking, so that the heat generated by the LED light-emitting chip is guided to the heat dissipation part through the mounting plate for dissipation.

[0044] Furthermore, the heat dissipation portion of the heat dissipation assembly is further provided with a through channel (not shown) corresponding to the opening 301 and used for accommodating the laser light source module.

[0045] like Figure 4 As shown, the laser light source module 20 includes a light emitting portion 201, a sealing groove 202 and a mounting surface 206, wherein the light emitting portion is a circular light emitting surface. It can be understood that in other embodiments, the shape of the light emitting portion 201 can also be square or other shapes. Furthermore, the laser light source module also includes a first cylinder for supporting the light emitting portion 201, and an annular step portion 203 connected in an annular direction along the first cylindrical carrier, and the step portion 203 is concentric with the light emitting portion. Instructions are required for the embodiment in which the light emitting portion 201 is square, the carrier of the light emitting portion 201 at this time is a first prismatic carrier, and the step portion at this time is a square step portion connected in an annular direction.

[0046] Furthermore, the laser light source module 20 includes a sealing groove 202 formed by an inward depression of the stepped portion 203. This sealing groove 202 is used to accommodate a rubber ring 40 when the laser light source module and the LED light source module are assembled. This rubber ring 40 seals the light-emitting element against dust, improving the luminous efficiency and reliability of the hybrid light source device. Specifically, the rubber ring 40 seals the LED light-emitting chip of the hybrid light source device and the light-emitting portion of the laser light source module within a single space, reducing the impact of dust on the light conversion efficiency of the light-emitting components.

[0047] Furthermore, the step portion 203 also includes a first inner wall 2031 and a first outer wall 2032 formed due to the inward recess of the sealing groove, wherein the first outer wall 2032 is slightly higher than the height of the first inner wall 2031. The advantage of this design is that the slightly lower first inner wall can provide more adjustment margin between the laser light source module and the LED light source module, and the slightly higher first outer wall can provide better sealing when assembled with the rubber ring 40.

[0048] Furthermore, the laser light source module also includes a second cylinder between the step portion 203 and the mounting surface 206, and a fool-proofing piece 204 for assembly positioning is provided on the surface of the second cylinder, wherein the fool-proofing piece 204 should match the size of the positioning portion 3011 of the heat dissipation assembly 30, so as to easily penetrate the positioning portion 3011 as best; it can be understood that by providing the fool-proofing piece 204, the laser light source assembly 20 is only allowed to be assembled along a certain angle direction, which can greatly improve the assembly accuracy of the hybrid light source device, thereby reducing the position adjustment time of the laser light source module.

[0049] Furthermore, the laser light source module also includes a mounting surface 206, wherein the mounting surface has a plurality of screw holes 205 for screw locking, wherein the hole walls of the screw holes 205 protrude from the mounting surface of the mounting surface 206. The advantage of this design is that when the mounting surface 206 of the laser light source module 20 is screwed to the back of the mounting plate of the heat sink assembly 30, the protruding portion of the screw hole 205 abuts the back of the mounting plate of the heat sink assembly, so that the mounting surface 206 of the laser light source module 20 and the back of the mounting plate of the heat sink assembly are directly abutted only through the protruding hole walls. In other words, there is an air gap between the mounting surface 206 of the laser light source module and the rest of the mounting plate of the heat sink assembly. The air gap greatly reduces the heat conduction between the heat sink assembly and the laser light source, preventing the heat of the heat sink assembly 30 from being transferred to the laser light source module 20 through the mounting plate, thereby affecting the luminous efficiency and reliability of the laser light source module. Corresponding to the above, the heat sink assembly 30 is used to provide support and fixation for the laser light source module, not for dissipating heat from the laser light source module. Therefore, the protruding screw hole design can greatly reduce the heat conduction between the heat sink assembly and the laser light source module. It should be noted that the laser light source module 20 is secured to the heat sink assembly 30 via blind holes on the inner side of the heat sink assembly, opposite the mounting surface. This means that the laser light source module is secured to the heat sink assembly 30 via screws on the inner side of the heat sink assembly 30. This method of attachment prevents the screw holes from being visible from the front of the hybrid light source device, improving the device's aesthetics. Furthermore, a plurality of heat sink fins 207 are provided on the back of the laser light source module mounting surface 206 to dissipate heat from the laser light source module.

[0050] like Figure 5As shown, it is a structural schematic diagram of the laser light source module 20. The laser light source module 20 includes a laser 211 arranged inside the shell, and a collimating lens 212 arranged on the optical path of the laser output light. The laser light source module 20 also includes a fluorescent plate 213 arranged at the light output portion 201. The laser light beam collected by the collimating lens 212 is incident on the light incident surface of the fluorescent plate. The fluorescent plate absorbs the laser light beam and converts the wavelength to emit fluorescence with different wavelengths of the laser. It should be noted that the fluorescence emitted after the fluorescent plate absorbs the laser wavelength conversion is Lambertian light, which is similar to the light distribution emitted by the LED light-emitting chip. Corresponding to the above, the fluorescence emitted by the fluorescent plate can also use the same collimating lens 105 as the LED light-emitting chip to improve the consistency of the light distribution collected by the LED light beam and the laser light beam.

[0051] Furthermore, the fluorescent sheet can be an organic fluorescent sheet composed of silica gel and fluorescent powder, or an inorganic fluorescent sheet composed of glass, ceramic and fluorescent powder. The fluorescent sheet is a common device in this field and will not be described in detail here.

[0052] The following is an explanation of the specific installation process.

[0053] 1. Assemble and fix the LED light source module and heat dissipation component.

[0054] 2. Place the laser light source module in the through-channel of the heat dissipation component so that the light output portion of the laser light source module is located at the bottom plate opening of the LED light source module. Adjust the horizontal position of the laser light source module by analyzing the light spot distribution of the LED light source module and the laser light source module.

[0055] 3. When the light spots emitted by the LED light source module and the laser light source module are concentric, screw the laser light source module to the heat dissipation assembly to complete the assembly of the hybrid light source device.

[0056] Compared with the prior art, the present invention achieves an optical effect in which the laser light source spot and the mixed light spot are concentric by making a two-dimensional horizontal adjustment of the laser light source as a whole relative to the LED light source, thereby further improving the optical effect of the mixed light source device.

[0057] Second embodiment

[0058] like Figures 6 to 8 As shown, the difference between the second embodiment and the first embodiment lies in the structure of the laser light source module and the assembly method of the entire hybrid light source device. It should be noted that the features identical to those of the first embodiment will not be described in detail, and only the differences from the first embodiment will be described, as follows:

[0059] The hybrid light source device of the second embodiment includes an LED light source module 110, a laser light source module 120, and a heat dissipation assembly 130; wherein the laser light source module 120 also includes a fixing plate 1201 integrally formed with the laser light source module housing and connected to the bottom plate of the LED light source module, and an external thread 1202 arranged on the surface of the laser light source module housing. Furthermore, the fixing plate 1201 is also provided with a plurality of first screw holes 1203 and a plurality of second screw holes 1204, wherein each first screw hole 1203 is a cylindrical hole of uniform aperture size, and each second screw hole 1204 is a stepped hole of varying aperture size, wherein the step height of the stepped hole should be higher than the height of the countersunk screw nut; further, the second screw hole 1204 connects the fixing plate 1201 of the laser light source module to the base plate of the LED light source module through a countersunk screw, so that the countersunk screw is completely hidden in the step of the second screw hole when locked, further improving the surface flatness of the fixing plate 1201, so that when the fixing plate 1201 is fixed to the heat dissipation component 130, the connection tightness and installation flatness will not be affected by the interference of the screw nut. It is understandable that in order to improve the heat conduction efficiency between the fixing plate and the base plate, a thermal conductive solder paste is also provided between the fixing plate and the base plate, and the thermal conductive solder paste helps to conduct the heat generated by the LED light source module through the base plate to the fixing plate, and then conduct it to the heat dissipation component through the fixing plate.

[0060] It should be noted that at this time, since the hybrid light source device is not installed with the heat dissipation component 130 and the laser light source radiator 140, the hybrid light source device is smaller in size and easier to transport. The heat dissipation component 130 and the laser light source radiator 140 can be installed when required by the customer and the application scenario, thereby increasing the assembly flexibility of the hybrid light source device.

[0061] Furthermore, when the heat dissipation component 130 is needed to provide heat dissipation, the heat dissipation component 14 is fixed to the fixing plate of the laser light source module by screwing the first screw hole 1203 on the inner side of the mounting surface of the heat dissipation component 130. It should be noted that in this embodiment, the heat dissipation component 130 can provide heat dissipation for the LED light source module and the laser light source module at the same time, and through simulation, a good steady-state heat dissipation effect can also be achieved.

[0062] Furthermore, the hybrid light source device also includes a laser light source radiator, which is used to dissipate heat from the laser light source module. The laser light source radiator 140 includes a mounting ring (not shown) and cooling fins arranged on the surface of the mounting ring, wherein the inner side of the mounting ring of the radiator 140 is provided with an internal thread that matches the external thread of the laser light source module. The radiator 140 is fixed to the laser light source module by screwing the threads, thereby further improving the heat dissipation efficiency of the laser light source module.

[0063] The following is an explanation of the specific installation process.

[0064] 1. Set the light output part of the laser light source module at the bottom opening of the LED light source module, adjust the horizontal position of the laser light source module, and analyze the light spot distribution of the LED light source module and the laser light source module.

[0065] 2. When the light spots emitted by the LED light source module and the laser light source module are concentric, the LED light source module and the laser light source module without a heat sink are fixed by countersunk screws to complete the assembly of the semi-finished hybrid light source device.

[0066] 3. Fix the heat dissipation assembly to the semi-finished hybrid light source device by screwing.

[0067] 4. Fix the heat sink to the laser light source module by screwing it.

[0068] The beneficial effect of this embodiment is that the hybrid light source device does not need to be installed with the heat dissipation component 130 and the laser light source radiator 140 when it is shipped, so that the hybrid light source device is smaller in size and convenient for transportation. The heat dissipation component 130 and the laser light source radiator 140 can be installed when required by the customer and the application scenario, thereby increasing the assembly flexibility of the hybrid light source device.

[0069] Third embodiment

[0070] like Figures 9 to 11 As shown, the difference between the third embodiment and the second embodiment lies in the different fixing plate structures of the laser light source module and the assembly method of the entire hybrid light source device. It should be noted that the features that are the same as other embodiments or that can be directly quoted from this embodiment will not be described in detail. Instead, only the differences from other embodiments will be described, which are as follows:

[0071] The hybrid light source device of the third embodiment includes an LED light source module 210, a laser light source module 220, and a heat dissipation assembly 230; wherein the laser light source module also includes an adjustment fixing plate 250 that is separately arranged from the laser light source module shell and is used to connect to the LED light source module base plate, wherein the adjustment fixing plate 250 of this embodiment is separately arranged from the shell of the laser light source module 220; compared with the integrally formed structure of the fixing plate 1201 and the shell of the laser light source module of the second embodiment, this embodiment can realize the adjustment of the laser light source module in three directions, further improving the adjustment accuracy of the hybrid light source device.

[0072] Furthermore, the adjustment fixing plate 250 includes a mounting plate 2501, and the mounting plate 2501 is provided with a sleeve portion 2502 for sleeve-mounting the laser light source module, and the sleeve portion has an opening 2503, and a fastening portion 2504 is provided in the opening 2503. In this embodiment, the fastening portion 2504 is a screw assembly, and the fixation between the laser light source module and the adjustment fixing plate is achieved by rotating the screw assembly.

[0073] In the above-mentioned first and second embodiments, the alignment of the light-emitting portion of the laser light source module with the light-emitting portion of the LED light-emitting chip is achieved through the machining accuracy of each structural component, that is, it is impossible to autonomously adjust the position of the light-emitting portion of the laser light source module in the vertical direction. In this embodiment, the position of the light-emitting portion of the laser light source module in the vertical direction can be adjusted by moving the laser light source module up and down in the sleeve portion 2502. When the light-emitting portion of the laser light source module is aligned with the light-emitting portion of the LED light-emitting chip, the laser light source module is fixed to the adjustment fixing plate 250 by the fastening portion 2504. At this time, the adjustment of the laser light source module in the vertical direction is completed. Then, the adjustment fixing plate 250 is moved by external force and the screw assembly to drive the adjustment of the horizontal position of the light-emitting portion of the laser light source module in the opening.

[0074] In summary, compared with the first and second embodiments, the laser light source module in this embodiment can not only be adjusted in the vertical direction relative to the LED light source module, but also can be adjusted in the horizontal direction relative to the LED light source module.

[0075] The following is an explanation of the specific installation process.

[0076] 1. Set the light-emitting part of the laser light source module at the bottom plate opening of the LED light source module, adjust the position of the laser light source module in the vertical direction relative to the LED light source module so that the light-emitting part of the laser light source module is flush with the light-emitting part of the LED light-emitting chip, and then fix the laser light source module on the adjustment fixing plate through the fastening part to achieve the vertical adjustment of the laser light source module relative to the LED light source module.

[0077] 2. Move the adjustment plate to adjust the horizontal position of the laser light source module and analyze the distribution of the light spots emitted by the LED and laser light source modules. When the light spots emitted by the LED and laser light source modules are concentric, screw the adjustment plate to the base plate of the LED light source module to complete the assembly of the semi-finished hybrid light source device, thus achieving horizontal adjustment of the laser light source module relative to the LED light source module.

[0078] 3. Fix the heat dissipation assembly to the semi-finished hybrid light source device by screwing.

[0079] 4. Fix the heat sink to the laser light source module by screwing it.

[0080] The beneficial effect of this embodiment is that the hybrid light source device does not need to be installed with the heat dissipation component 130 and the laser light source radiator 140 when it is shipped, so that the hybrid light source device is smaller in size and convenient for transportation. The heat dissipation component 130 and the laser light source radiator 140 can be installed when required by the customer and the application scenario, thereby increasing the assembly flexibility of the hybrid light source device.

[0081] In addition, the hybrid light source device of this embodiment can simultaneously adjust the vertical and horizontal positions of the laser light source module relative to the LED light source module, further improving the light output effect of the hybrid light source device.

[0082] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0083] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention.
