[0025] As described in the background technology, currently, in daily lighting or filming of movies and TV dramas, sometimes people hope that the beam angle of the lighting beam is as small as possible, so as to create a Tyndall effect and obtain a clear beam of light. Sometimes people hope that the beam angle of the lighting beam is as large as possible, so as to increase the size of the light spot and expand the coverage area of the beam. The existing lighting system that can reduce the beam angle of the lighting beam and the lighting system that can increase the beam angle of the lighting beam are usually two independent lighting systems. After the two independent lighting systems are assembled into one lighting system, although the lighting system can emit both a lighting beam with a smaller beam angle and a lighting beam with a larger beam angle, the volume of the lighting system will be very large and it is also inconvenient to carry.
[0026] Reference Figure 1 and Figure 2 In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a lighting system, which includes a mounting tube 100, a first light source 200, a second light source 300 and a focusing lens 400, wherein a mounting space is provided in the mounting tube 100, and a light outlet is formed on an end surface of a first end of the mounting tube 100; the first light source 200 is provided in the mounting space, and has a first light-emitting end 210 that emits light toward the light outlet; the second light source 300 is provided in the mounting space, and is located on a side of the first light source 200 close to the light outlet, and has a second light-emitting end 310 that emits light toward the light outlet, the beam angle of the light beam emitted by the second light-emitting end 310 is greater than the beam angle of the light beam emitted by the first light-emitting end 210, and the second light source 300 is provided with an irradiation through hole 530 for allowing the light beam emitted by the first light-emitting end 210 to irradiate toward the light outlet; the focusing lens 400 is provided in the mounting space, and is located on a side of the second light source 300 close to the light outlet, and is used to focus the light beam emitted by the first light-emitting end 210 or the second light-emitting end 310.
[0027] In the embodiment of the present application, the interior of the installation tube 100 is hollow to form an installation space, and the shape of the installation space is a cylindrical groove, and the groove is coaxial with the installation tube 100. Of course, in other embodiments, the installation space can also be a groove of other three-dimensional shapes. The end surface of the first end of the installation tube 100 is open to form a light outlet; the first light source 200 can be a white laser light source or SLD (English full name: Super luminescent Diode, Chinese full name: super luminescent diode) light source, the first light source 200 is fixedly installed in the installation space and can be coaxial with the installation tube 100, and the first light-emitting end 210 can also be coaxial with the installation tube 100; the second light source 300 can be a COB (English full name: Chip-on-Board, Chinese full name: chip-level packaging) light source, the second light source 300 is fixedly installed in the installation space and can be coaxial with the installation tube 100, and the second light-emitting end 310 can also be coaxial with the installation tube 100; the extension direction of the irradiation through hole 530 can be parallel to the axial direction of the installation tube 100, so that the light beam emitted by the first light-emitting end 210 can pass through the irradiation through hole 530 to irradiate the side of the second light source 300 away from the first light source 200; the focusing lens 400 can be a focusing convex lens or a Fresnel lens, the focusing lens 400 is fixedly installed in the installation space, and can be coaxial with the installation tube 100, and can completely cover the light outlet, that is, the outer peripheral surface of the focusing lens 400 is tightly fitted with the inner wall surface of the light outlet.
[0028] The light beam emitted by the first light-emitting end 210 of the first light source 200 in the present application is irradiated onto the focusing lens 400 through the irradiation through hole 530, and is formed into a concentrated light beam with a smaller beam angle after being focused by the focusing lens 400, so as to produce the Tyndall effect; the light beam emitted by the second light-emitting end 310 of the second light source 300 is directly irradiated onto the focusing lens 400, and is formed into a floodlight beam with a larger beam angle after being focused by the focusing lens 400, so that the coverage area of the light beam can be expanded; the lighting system in the present application can not only emit a concentrated light beam with a smaller beam angle and a floodlight beam with a larger beam angle with the cooperation of fewer components such as the first light source 200, the second light source 300 and the focusing lens 400, but also the first light source 200, the second light source 300 and the focusing lens 400 and other components are all installed in the installation tube 100; the above-mentioned design not only reduces the number of components in the lighting system, but also greatly reduces the volume of the lighting system, thereby facilitating the transportation of the lighting system, and then facilitating the use of the lighting system in various different venues, greatly broadening the scope of use of the lighting system.
[0029] Reference Figure 1 and Figure 2The lighting system in this embodiment also includes a light guide portion 500, which is at least partially embedded in the irradiation through hole 530. The light guide portion 500 has a first end surface 510 and a second end surface 520 that are arranged opposite to each other. The first end surface 510 corresponds to the first light-emitting end 210, and the second end surface 520 is located on a side of the first end surface 510 close to the light outlet. The light guide portion 500 can guide the light beam emitted by the first light-emitting end 210 from the first end surface 510 to the second end surface 520.
[0030] In the embodiment of the present application, the light guide 500 is fixedly embedded in the irradiation through hole 530. The light guide 500 can be a cylindrical light guide column and can be coaxial with the mounting tube 100. Of course, in other embodiments, the light guide 500 can also be a light guide column of other three-dimensional shapes. The light guide 500 is arranged to facilitate guiding most of the light emitted by the first light emitting end 210 from the first end surface 510 to the second end surface 520, and emitting from the second end surface 520 toward the position of the focusing lens 400, so as to obtain a brighter concentrated light beam with a smaller beam angle.
[0031] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the second end face 520 at least partially covers the first end face 510. In this optional method, the light guide portion 500 is cylindrical, and the radius of the second end face 520 is greater than or equal to the radius of the first end face 510. Such a design facilitates the light emitted by the first light-emitting end 210 to be directed more toward the direction of the focusing lens 400. Of course, in other embodiments, the light guide portion 500 can also be presented in other three-dimensional shapes, such as a cuboid or a hexagonal prism, and the second end face 520 can not only completely cover the first end face 510, but also the area of the second end face 520 is greater than or equal to the area of the first end face 510.
[0032] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the inclination of the light guide portion 500 is 1° to 5°. In this optional method, the inclination of the light guide portion 500 is 1°. The inclination of the light guide portion 500 is limited to 1° to 5°, mainly to make the black spot at the center of the spot of the floodlight beam with a larger beam angle smaller.
[0033] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the light guide portion 500 is coaxial with the first light emitting end 210, and the radius of the second end surface 520 is greater than or equal to the radius of the first end surface 510. Such a design allows more light emitted from the first light emitting end 210 to be guided into the light guide portion 500 and directed toward the focusing lens 400 through the light guide portion 500.
[0034] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the focusing lens 400 is coaxial with the second light-emitting end 310, the first light-emitting end 210 is coaxial with the second light-emitting end 310, and the focus of the focusing lens 400 is located on the second light-emitting end 310. Such a design can not only maximize the use of the light emitted by the first light-emitting end 210 and the light emitted by the second light-emitting end 310, thereby improving the intensity and brightness of the light beam focused by the focusing lens 400, but also improve the quality of the light beam focused by the focusing lens 400, and in addition, reduce the loss of the light beam during transmission.
[0035] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the radius of the first light-emitting end 210 is D1, the radius of the second light-emitting end 310 is D2, the radius of the first end surface 510 is D3, the radius of the second end surface 520 is D4, the radius of the focusing lens 400 is D5, the length of the light-guiding portion 500 is H1, and the distance from the focusing lens 400 to the second light-emitting end 310 is H2. The ratios of D1, D2, D3, D4, D5, H1, and H2 are 0.5 / π: 5: 0.8: 0.8+6*tan1°: 25: 6: 28.
[0036] In a specific embodiment, the specific values of D1, D2, D3, D4, D5, H1, and H2 are 0.5 / π, 5, 0.8, 0.8+6*tan1°, 25, 6, and 28, respectively. The units of the above values are all mm. At the same time, in this case, the inclination of the guide column is 1°. Through experiments, it can be known that according to the lighting system composed of the above parameters, when the first light-emitting end 210 is emitting light, the lighting system can produce a spotlight beam with a beam angle of 1.7°, and when the second light-emitting end 310 is emitting light, the lighting system can produce a floodlight beam with a beam angle of 18.6. Of course, the first light-emitting end 210 and the second light-emitting end 310 can emit light at the same time. In this case, the lighting system can produce a light beam with a beam angle between 1.8° and 1.9°.
[0037] In addition, according to the law of conservation of optical extension: π*S1*sin(β)^2=π*S2*sin(α)^2, wherein S1 is the area of the first light-emitting end 210 or the area of the second light-emitting end 310, S2 is the area of the focusing lens 400, α is the beam angle of the light beam emitted through the focusing lens 400, and β is the beam angle of the light beam emitted through the first light-emitting end 210 or the beam angle of the light beam emitted through the second light-emitting end 310. From the above, it can be seen that, when the area of the first light-emitting end 210 or the area of the second light-emitting end 310 remains unchanged, when the area of the focusing lens 400 becomes larger, the beam angle of the light beam emitted through the focusing lens 400 will become smaller, and when the area of the focusing lens 400 becomes smaller, the beam angle of the light beam emitted through the focusing lens 400 will become larger; when the area of the focusing lens 400 remains unchanged, when the area of the first light-emitting end 210 or the area of the second light-emitting end 310 becomes larger, the beam angle of the light beam emitted through the focusing lens 400 will become larger, and when the area of the first light-emitting end 210 or the area of the second light-emitting end 310 becomes smaller, the beam angle of the light beam emitted through the focusing lens 400 will become smaller.
[0038] Reference Figure 1 As an optional method in the embodiment of the present application, the lighting system further includes a heat sink 600, which is mounted on the second light source 300. The heat sink 600 is conducive to heat dissipation of the second light source 300, thereby facilitating the extension of the service life of the second light source 300.
[0039] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the heat sink 600 is fixedly mounted on the surface of the second light source 300 away from the light outlet, and the surface of the heat sink 600 close to the second light source 300 completely covers the surface of the second light source 300 close to the heat sink 600. Such a design improves the heat dissipation efficiency; the heat sink 600 has a mounting through hole 610 coaxial with the irradiation through hole 530, and the light guide portion 500 is partially embedded in the mounting through hole 610.
[0040] In this optional manner, the heat sink 600 is a heat dissipation copper block, the heat dissipation copper block is coaxial with the second light source 300 , the mounting through hole 610 is coaxial with the irradiation through hole 530 , and the light guide portion 500 is fixedly embedded in the mounting through hole 610 .
[0041] Reference Figure 1 and Figure 2 As an optional method in the embodiment of the present application, the first end surface 510 is in contact with the first light-emitting end 210, and the second end surface 520 is flush with the second light-emitting end 310. Such a design is conducive to directing more light emitted by the first light-emitting end 210 toward the direction of the focusing lens 400.
[0042] Reference Figure 1As an optional method in the embodiment of the present application, the light guide part 500 is a light guide column. Of course, in other embodiments, the light guide part 500 can also be an optical fiber, an optical waveguide or a grating. In addition, the light guide column is made of quartz glass. Since quartz glass has good heat resistance, such a design is conducive to extending the service life of the light guide column.
[0043] Reference Figure 1 As an optional method in the embodiment of the present application, the first light source 200 is a white laser light source or an SLD light source. The white laser light source has the characteristics of a wide spectrum and can provide a higher spectral resolution and color reproduction capability. The full name of SLD in English is Super luminescent Diode, and the full name in Chinese is super radiant diode. The SLD light source can provide a wide spectrum, incoherent light with high brightness and short coherence length. Of course, in other embodiments, the first light source 200 can also be a laser light source or other light source that can generate a light beam with a smaller beam angle.
[0044] Reference Figure 1 As an optional method in the embodiment of the present application, the second light source 300 is a COB light source. COB is called Chip-on-Board in English and chip-level packaging in Chinese. COB light sources have the advantages of high brightness, uniform light spot, good thermal management, compact structure and high efficiency. Of course, in other embodiments, the second light source 300 can also be other surface light sources.
[0045] Reference Figure 1 As an optional method in the embodiment of the present application, the focusing lens 400 is a focusing convex lens or a Fresnel lens. The focusing convex lens is a spherical convex lens, which is thicker in the center and gradually thinner toward the edge. It can focus parallel light to a focal point. The Fresnel lens is a special lens, which is composed of a series of concentric rings or cylindrical rings, and the lens surface on each ring has a gradually decreasing radius of curvature. This design makes the Fresnel lens have the characteristics of simple structure, less material required, light weight, low difficulty in processing and manufacturing, and low processing and manufacturing cost compared to ordinary lenses with complex curved shapes.
[0046] In summary, the lighting system provided by the present embodiment has at least the following beneficial technical effects: the light beam emitted by the first light-emitting end 210 of the first light source 200 in the present application is irradiated onto the focusing lens 400 through the irradiation through hole 530, and is formed into a concentrated light beam with a smaller beam angle after being focused by the focusing lens 400, thereby being used to produce the Tyndall effect; the light beam emitted by the second light-emitting end 310 of the second light source 300 is directly irradiated onto the focusing lens 400, and is formed into a floodlight beam with a larger beam angle after being focused by the focusing lens 400, thereby expanding the coverage area of the light beam; The lighting system can not only emit a spotlight beam with a smaller beam angle and a floodlight beam with a larger beam angle with the cooperation of fewer components such as the first light source 200, the second light source 300 and the focusing lens 400, but also the first light source 200, the second light source 300 and the focusing lens 400 and other components are all installed in the installation tube 100; the above-mentioned design not only reduces the number of parts in the lighting system, but also greatly reduces the volume of the lighting system, thereby facilitating the transportation of the lighting system, and then facilitating the use of the lighting system in various different venues, greatly broadening the scope of use of the lighting system.
