[0034] Figure 1 is a schematic view of the laser coupling device according to an embodiment of the present application. Figure 2 is Figure 1 is a schematic view of the laser light source module. Figure 3 is Figure 2 is a partial sectional view of the laser light source module. Figure 4 is a sectional view of the laser coupling device according to another embodiment of the present application.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , the laser light source module 10 comprises a first laser light source 110 (laser light source) and a first light collecting element 120 (light collecting element), and the laser coupling device 100 comprises the laser light source module 10, a first light transmission element 130, a light guiding element 140, a second light collecting element 150 and a second light transmission element 160. The first laser light source 110 comprises a seat portion 111, a shell portion 112 and a light emitting portion 113 (drawn in Figure 3). The shell 112 has opposite bottom end B and light exit end E. The bottom end B is fixed to the base 111, and the light emitting part 113 is disposed in the base 111 and inside the shell 112. The light emitting part 113 is adapted to generate a first laser beam L1. The first light collecting element 120 is fixed to the light exit end E of the shell 112 or the base 111 and is located on the transmission path of the first laser beam L1. The first light transmitting element 130 is adapted to transmit a second laser beam L2. The light guiding element 140 is disposed downstream of the light path of the first light transmitting element 130. The second light collecting element 150 is disposed downstream of the light path of the light guiding element 140 and the first light collecting element 120. The second light transmitting element 160 is located downstream of the light path of the second light collecting element 150, wherein the second light collecting element 150 is adapted to couple the first laser beam L1 and the second laser beam L2 to the second light transmitting element 160.

[0036] Please continue to refer to Figure 2 and Figure 3 In an embodiment, the first laser source 110 can include a white laser source, and the first laser beam L1 is a white laser beam, for example. In detail, the white laser beam has a wider wavelength range than other monochromatic laser beams, so that the wavelength of the second laser beam L2 has more choices. In the embodiment, the white laser beam can be formed by converting a blue laser beam. For example, in an embodiment, the first laser source 110 can further include a laser source part 114, and the laser source part 114 is adapted to emit a laser beam L. Further, the laser beam L is a blue laser beam, for example, and the light emitting part 113 can be provided with a material such as a fluorescent powder or a phosphor powder that can convert the wavelength of the laser beam, so as to convert the laser beam L (blue laser beam) into the first laser beam L1 (white laser beam). The laser source part 114 can include a blue light emitting chip, but the present application is not limited thereto. In addition, the present application does not limit the specific means of generating a white laser beam. In the embodiment, the first laser source 110 includes a TO-CAN packaged white laser diode, for example, but other embodiments are not limited thereto.

[0037] The first light-converging element 120 of the present embodiment can guide the first laser beam L1 to the light guide element 140. Specifically, the first laser beam L1 generated by the light emitting portion 113 is slightly divergent, for example, and the first light-converging element 120 can converge the first laser beam L1 in a divergent state so that the first laser beam L1 can be incident on the light guide element 140 as a substantially parallel beam or a slightly convergent beam. The first light-converging element 120 includes a biconvex aspherical lens, for example. In detail, because the first light-converging element 120 is fixed to the light emitting end E of the housing portion 112, the distance between the first light-converging element 120 and the light emitting portion 113 is significantly reduced. Therefore, the first light-converging element 120 can employ a biconvex aspherical lens to significantly shorten the focal length of the first light-converging element 120 so that the first laser beam L1 can be substantially a parallel beam or a slightly convergent beam after passing through the first light-converging element 120. Incidentally, Figure 2 With Figure 3 the structure of the biconvex aspherical lens (i.e., the first light-converging element 120) shown in Figure 4 is merely an example. For example, referring to Figure 3 , the first light-converging element 120a of the laser coupling device 100a can be a biconvex aspherical lens, but the shape of the first light-converging element 120a is different from that of the first light-converging element 120 of

[0038] Referring to Figure 1 , the first light-converging element 130 can guide the second laser beam L2 to the light guide element 140. The first light-converging element 130 includes an optical fiber, for example. Further, the optical fiber can be coupled to a second laser light source (not shown) to transmit the second laser beam L2 generated by the second laser light source to the light guide element 140. The wavelength of the second laser beam L2 can be different from that of the first laser beam L1. For example, in an embodiment, the first laser beam L1 can include a white laser beam, and the second laser beam L2 can include a red laser beam, but the present application is not limited thereto.

[0039] In the present embodiment, the light guide element 140 can guide the second laser beam L2 emitted from the first light-converging element 130 to the second light-converging element 150. The light guide element 140 includes a triangular prism, for example. Further, the light guide element 140 can include light guide surfaces S1, S2, and S3 connected to each other, wherein the light guide surface S1 can be provided for the second laser beam L2 to be incident, and the light guide surface S2 can reflect the second laser beam L2 to the light guide surface S3 so that the second laser beam L2 is emitted from the light guide surface S3. In the present embodiment, the light guide surfaces S1 and S3 can be substantially perpendicular to each other, but the present application is not limited thereto.

[0040] In the present embodiment, the second light collecting element 150 receives the first laser beam L1 emitted from the first light collecting element 120 and the second laser beam L2 emitted from the light guide element 140, converges and couples the first laser beam L1 and the second laser beam L2 to the second light transmission element 160. The second light collecting element 150 can comprise an aspheric lens, for example, a lenticular lens, and the material of the second light collecting element 150 can comprise glass. It is noted that the focal length of the second light collecting element 150 is greater than the focal length of the first light collecting element 120. On the other hand, since the second light collecting element 150 is required to receive the first laser beam L1 and the second laser beam L2 together, the volume of the second light collecting element 150 can be greater than the volume of the first light collecting element 120.

[0041] The second light transmission element 160 transmits the first laser beam L1 and the second laser beam L2 coupled with each other, so as to guide the first laser beam L1 and the second laser beam L2 coupled with each other to be emitted from the laser coupling device 100. The second light transmission element 160, for example, comprises an optical fiber.

[0042] Compared with the prior art, the laser light source module 10 of the present embodiment adopts the first light collecting element 120 to focus the first laser beam L1 generated by the first laser light source 110, wherein the first light collecting element 120 is fixed to the light emitting end E of the shell portion 112 of the first laser light source 110, so as to greatly shorten the distance of the first laser beam L1 from the first laser light source 110 to the first light collecting element 120. Therefore, the laser light source module 10 of the present embodiment can reduce the energy loss of the first laser beam L1, thereby improving the light utilization rate. The laser coupling device 100 of the present embodiment adopts the laser light source module 10, so as to improve the light utilization rate. In addition, since the first light collecting element 120 is fixed to the shell portion 112 of the first laser light source 110 instead of being separated from the first laser light source 110, the space required for arranging the first light collecting element 120 can be greatly reduced, thereby effectively reducing the volume of the laser coupling device 100.

[0043] Figure 5 is a schematic view of a laser coupling device according to another embodiment of the present application. Figure 6 is Figure 5 is a schematic view of a first laser light source separated from a shell. Figure 7 is Figure 5 is an exploded schematic view of a laser coupling device omitting a first laser light source. The structure and advantages of the laser coupling device 100b of the present embodiment are similar to those of the embodiment of Figure 1 Figure 5 Figure 6 ​​The laser coupling device 100b can further include a housing 170, a light transmission base 180, and a calibration assembly 190. The housing 170 has a first side 171, a second side 172, and a light exit side 173. The first side 171 and the light exit side 173 are opposite, and the second side 172 is between the first side 171 and the light exit side 173. The first laser light source 110 is fixed to the first side 171. Please refer to Figure 5 and Figure 7 The light transmission base 180 has a light transmission portion 181 and a locking portion 182 connected. The locking portion 182 is connected to the second side 172, and the light transmission portion 181 is connected to the locking portion 182 and the first light transmission element 130 (shown in Figure 7 ). The calibration assembly 190 includes a plurality of locking members 191 and a pad member 192 (also shown in Figure 6 ). The pad member 192 is pressed between the second side 172 and the locking portion 182, and the locking members 191 pass through the locking portion 182 and the pad member 192 and extend into the second side 172. Further, please continue to refer to Figure 5 The light guide element 140 (shown in Figure 1 and Figure 4 ) can be located in the housing 170 and close to the second side 172, and by adjusting the depth of each locking member 191 extending into the second side 172, the force of each locking member 191 pressing against the pad member 192 can be changed. In this way, the first light transmission element 130 can be slightly inclined relative to the second side 172, thereby slightly changing the angle of the second laser beam L2 incident to the light guide element 140.

[0044] In addition, the locking members 191 can also fix the light transmission base 180 to the second side 172 of the housing 170. The locking members 191 of the present embodiment can include screws. In detail, the screws can be first screwed into and locked to the second side 172, and then slightly unscrewed from the second side 172, thereby adjusting the angle of the second laser beam L2 (shown in Figure 1 and Figure 4 ) incident to the light guide element 140 (shown in Figure 1 ). However, the present application does not limit the specific operation method of the screws. It is worth mentioning that the number of locking members 191 of the present embodiment can be at least four, so that not only the firmness of the locking light transmission base 180 can be improved, but also the incident angle of the second laser beam L2 can be more accurately adjusted. The laser coupling device 100b includes, for example, four locking members 191, but the present application is not limited thereto.

[0045] Please refer to Figure 5 and Figure 7The gasket 192 of the present embodiment includes, for example, a gasket P. Further, since the gasket P can be designed as an integral structure, it has the advantage of being easy to assemble. The gasket P can be made of a material having ductility, for example, the material of the gasket P can include rubber, silicone or metal, but the present application is not limited thereto. Incidentally, all the locking members 191 of the present embodiment pass through the gasket P.

[0046] Figure 8 is a schematic view of a laser coupling device of another embodiment of the present application. Figure 9 is Figure 8 is a schematic view of a housing, a light transmission seat, a calibration assembly and a first light transmission element of a laser coupling device of another embodiment of the present application, which are separated from each other. Figure 6 is Figure 8 and Figure 9 The gasket 192c includes, for example, a plurality of grommets R. In detail, the number of grommets R is the same as the number of locking members 191, and each locking member 191 passes through each grommet R and extends into the second side 172. In this way, the force with which the gasket 192c pushes against each locking member 191 can be improved, so that the angle at which the second laser beam L2 (shown in Figure 1 and Figure 4 ) is incident on the light guide element 140 (shown in Figure 1 and Figure 4 ) can be more easily adjusted. Similarly, the material of the grommet R includes, for example, rubber, silicone or metal, but other embodiments are not limited thereto.

[0047] Figure 10 is a schematic view of a housing, a light transmission seat, a calibration assembly and a first light transmission element of a laser coupling device of another embodiment of the present application, which are separated from each other. Figure 11 is Figure 10 is a partial cross-sectional schematic view of a housing, a light transmission seat and a calibration assembly of a laser coupling device of another embodiment of the present application, which are assembled with each other. Figure 9 is Figure 10 and Figure 11 The second side 172d of the housing 170d can have a plurality of grooves G. The grommets R are respectively arranged in the grooves G, and the local part RP of each grommet R respectively protrudes from each groove G. The locking part 182 is pressed against the local part RP of the grommet R, so that the grommet R can be more stably fixed to the second side 172d when pressed by the locking part 182. It can be understood that the number of grooves G is the same as the number of grommets R.

[0048] Figure 12 is a schematic view of a laser coupling device of another embodiment of the present application. The structure and advantages of the laser coupling device 100e of the present embodiment are similar to those of the embodiment of Figure 1 , and only the differences will be described below. Please refer toFigure 12 The laser coupling device 100e can further include a light homogenizing plate D disposed between the second light collecting element 150 and the second light transmitting element 160. In detail, the light homogenizing plate D can shield stray light of the first laser beam L1 and homogenize the spot of the first laser beam L1, so that the first laser beam L1 can be more uniformly and centrally incident to the second light transmitting element 160. In this way, the light collecting effect of the second light transmitting element 160 can be effectively improved, and the light utilization of the laser coupling device 100e is further improved. It is incidentally mentioned that the light homogenizing plate D can include a fogging quartz light homogenizing plate, and in an embodiment, the thickness of the fogging quartz light homogenizing plate can be about 1 mm, but the present application is not limited thereto.

[0049] Figure 13 is a partial cross-sectional schematic view of a laser light source module of a laser coupling device according to another embodiment of the present application. The laser coupling device 100f and the laser light source module 10f of the present embodiment are similar to the laser coupling device 100 and the laser light source module 10 of the embodiment of Figure 1 , and only the differences are described below. Please refer to Figure 13 The first light collecting element 120f is fixed to the seat portion 111 and covers the light emitting portion 113. The laser light source portion 114 is fixed to the seat portion 111 of the first laser light source 110 and is adapted to emit a laser beam L toward the first light collecting element 120f. The first light collecting element 120f is adapted to converge the laser beam L to the light emitting portion 113, and the light emitting portion 113 is adapted to convert the laser beam L into the first laser beam L1. In detail, the laser beam L can be focused to the light emitting portion 113 by the first light collecting element 120f, and the distance between the first light collecting element 120f and the light emitting portion 113 is greatly shortened, so that more first laser beams L1 emitted from the light emitting portion 113 are incident to the first light collecting element 120f, thereby improving the light utilization. In addition, since the laser beam L can be more centrally incident to the light emitting portion 113 by the first light collecting element 120f, and the distance between the first light collecting element 120f and the light emitting portion 113 is greatly shortened, the first laser beam L1 can also be made to be more close to a parallel beam emitted from the shell portion 112. In this way, the chaotic light spot generated by the reflection of the first laser beam L1 inside the shell portion 112 can be reduced or eliminated, thereby reducing the generation of stray light. For example, the laser coupling device 100f of the present embodiment can omit the light homogenizing plate D of Figure 12 , but other embodiments are not limited thereto. In the present embodiment, the first light collecting element 120f can include a meniscus lens, but the present application is not limited thereto.

[0050] In summary, the laser light source module of the utility model adopts the first light collecting element to focus the first laser beam generated by the first laser light source, wherein the first light collecting element is fixed to the light emitting end of the shell part of the first laser light source, so as to greatly shorten the distance of the first laser beam from the first laser light source to the first light collecting element. Therefore, the laser light source module of the utility model can reduce the energy loss of the first laser beam, and further improve the light utilization rate. The laser coupling device of the utility model adopts the above laser light source module, so the light utilization rate can be improved. In addition, since the first light collecting element is fixed to the shell part of the first laser light source instead of being separated from the first laser light source, the space required for arranging the first light collecting element can be greatly reduced, and the volume of the laser coupling device can be effectively reduced.
