DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0029] The technical solutions in the implementation scheme of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation scheme of the utility model.

[0030] See also Figure 1 The present utility model embodiment provides a light source device 20, which can generate outgoing light in a certain direction, thereby helping to realize the lighting function of the light source device 20. The light source device 20 can be used in the field of stage lights, such as beam lights, follow-spot lights, etc.; or the light source device 20 can also be used in the fields of searchlights or rescue lights.

[0031] See also Figure 1 and Figure 2 The light source device 20 may include a light emitting component 400 and a lens component 10. The light emitting component 400 may be used to generate outgoing light. The lens component 10 may be located in the optical path of the outgoing light of the light emitting component 400. The lens component 10 may reflect or transmit the outgoing light of the light emitting component 400, thereby helping the outgoing light of the light emitting component 400 to be emitted in a specific direction.

[0032] There are many options for the light-emitting component 400. For example, the light-emitting component 400 may be an LED light-emitting component; for another example, the light-emitting component 400 may be a laser light-emitting component; for another example, the light-emitting component 400 may be a fluorescent lamp light-emitting component. The specific selection can be made according to the actual needs of the light source device 20.

[0033] The specific structure of the lens assembly 10 can refer to the following embodiments. Since the light source device 20 adopts all the technical solutions of all the following embodiments, it has at least all the beneficial effects brought by the technical solutions of the following embodiments, which will not be repeated here.

[0034] See also Figure 2 , Figure 8 and Fig. 9 In some embodiments, the number of light-emitting components 400 and the number of lens components 10 can be multiple, wherein the number of light-emitting components 400 can be the same as the number of lens components 10, thereby facilitating the multiple lens components 10 to respectively reflect or transmit the output light of the multiple light-emitting components 400.

[0035] See also Figure 1 and Figure 2 The present invention also provides a lens assembly 10, which can be used to reflect or transmit the light emitted by the light emitting assembly 400, and helps the light emitted by the light emitting assembly 400 to be emitted in a specific direction. In the following embodiments, the lens assembly 10 is mainly applied to the light source device 20 as an example for description.

[0036] See also Figures 1 to 3 The lens assembly 10 may include a base 100 and a lens 200. The base 100 may include a first support surface 110, a second support surface 120, and a positioning boss 130. The positioning boss 130 may be convexly disposed on the second support surface 120. The positioning boss 130 may have a positioning surface 131. The positioning surface 131 may be arranged at an angle with the first support surface 110. The lens 200 may be attached to the positioning surface 131 and abut against the first support surface 110. In this way, the positioning surface 131 may be arranged at an angle with the first support surface 110, and the lens 200 may be attached to the positioning surface 131 and abut against the first support surface 110, so that the lens 200 may be positioned by the positioning surface 131 and the first support surface 110, thereby facilitating the lens 200 to be accurately mounted on the base 100. In addition, the lens 200 is mounted on the second supporting surface 120 through the positioning surface 131 of the positioning boss 130, which helps to reduce the contact area between the lens 200 and the base 100, thereby helping to reduce the risk of the base 100 transmitting the vibration it bears to the lens 200 and causing the lens 200 to break. Moreover, the lens 200 is mounted on the second supporting surface 120 through the positioning surface 131 of the positioning boss 130, so that there is a gap between the lens 200 and the second supporting surface 120, thereby helping the airflow inside the base 100 to flow in the gap between the lens 200 and the second supporting surface 120, thereby helping the lens 200 to dissipate heat.

[0037] It can be understood that the positioning surface 131 and the first support surface 110 are arranged at an angle, so that the positioning surface 131 and the first support surface 110 can position and limit the lens 200 from different directions. In addition, the positioning surface 131 and the first support surface 110 have a small area, which is helpful for processing the positioning surface 131 and the first support surface 110, thereby helping to improve the processing accuracy of the positioning surface 131 and the first support surface 110, and further helping the lens 200 to fit more accurately on the positioning surface 131 and the first support surface 110. Among them, the angle formed by the positioning surface 131 and the first support surface 110 can be designed according to the position where the lens 200 is installed on the base 100.

[0038] See also Figure 2 and Figure 3The base 100 may be a plate structure or a frame structure, and the base 100 may be made of materials such as copper, aluminum or stainless steel, so that the base 100 has high strength and stability.

[0039] The first supporting surface 110 may be a surface of the base 100 , wherein the first supporting surface 110 may be a curved surface; or, the first supporting surface 110 may be a flat surface.

[0040] The second support surface 120 may be a surface of the base 100 , wherein the second support surface 120 may be a curved surface; or, the second support surface 120 may be a flat surface.

[0041] There may be various relationships between the second support surface 120 and the first support surface 110. For example, the second support surface 120 may be spaced apart from the first support surface 110 and disposed at an angle; for another example, the second support surface 120 may be connected to the first support surface 110 and disposed at an angle.

[0042] The positioning boss 130 may be protruded from the second supporting surface 120 , and the positioning boss 130 may be a positioning block. The positioning surface 131 of the positioning boss 130 may be located on a side of the positioning boss 130 away from the second supporting surface 120 , and the positioning surface 131 may be a plane.

[0043] The base 100 may further include a third support surface 170, which may be a surface of the base 100 and may be connected to the second support surface 120. The elastic pressing member 320 connected to the base 100 may be located on the third support surface 170, and the second support surface 120 may be located between the third support surface 170 and the first support surface 110.

[0044] The lens assembly 10 may further include an elastic pressing member 300, which may be connected to the base 100 and press the side of the lens 200 away from the positioning boss 130, so that the elastic pressing member 300 may exert a force on the lens 200, thereby helping the lens 200 to stably fit the positioning surface 131 of the positioning boss 130 and preventing the lens 200 from easily detaching from the positioning surface 131 due to external force collision.

[0045] There are many options for the elastic pressure member 300. For example, the elastic pressure member 300 can be a spring, wherein one end of the spring can be fixedly connected to the base 100, and the other end of the spring can be pressed against the lens 200; for another example, the elastic pressure member 300 can be a spring, wherein one end of the spring can be connected to the base 100 through a fixed plate, and the other end of the spring can be pressed against the lens 200. The spring can be located between the fixed plate and the lens 200, and the length direction of the spring can be roughly perpendicular to the plane where the lens 200 is located.

[0046] See also Figure 2 and Figure 4 In some embodiments, the elastic pressure member 300 may include a connecting portion 310, which may be a connecting plate, thereby helping to increase the contact area between the connecting portion 310 and the third supporting surface 170 of the base 100, thereby helping to reduce the risk of stress concentration due to a small contact area between the connecting portion 310 and the third supporting surface 170 of the base 100.

[0047] The connection portion 310 may be connected to the base 100 . For example, the connection portion 310 may be fixedly connected to the third support surface 170 of the base 100 by welding or screw connection, thereby facilitating the elastic pressing member 300 to be fixedly connected to the base 100 .

[0048] The elastic pressing member 300 may further include an elastic pressing portion 320 , which may be connected to the connecting portion 310 . The elastic pressing portion 320 may press the lens 200 , thereby helping the elastic pressing member 300 to press against the lens 200 , and further helping the lens 200 to fit tightly against the positioning surface 131 and abut against the first support surface 110 .

[0049] The elastic pressing portion 320 can extend from the connecting portion 310 to the end of the lens 200 abutting against the first supporting surface 110, and the elastic pressing portion 320 can press the side of the lens 200 away from the positioning boss 130. In this way, the elastic pressing portion 320 can be bent from the connecting portion 310 to the end of the lens 200 abutting against the first supporting surface 110, so as to help realize that the elastic pressing portion 320 can tightly press the side of the lens 200 away from the positioning boss 130, and the structure is relatively simple and compact, easy to manufacture, and convenient to operate.

[0050] Among them, when the number of positioning bosses 130 is one, the position where the elastic pressing portion 320 presses against the lens 200 can be located on the lens 200 connected to the positioning boss 130; when the number of positioning bosses 130 is two, the position where the elastic pressing portion 320 presses against the lens 200 can be located on the lens 200 between the two positioning bosses 130, and the specific selection can be made according to the number of positioning bosses 130.

[0051] Please continue reading Figure 2 and Figure 4In some embodiments, the end of the elastic pressing portion 320 away from the connecting portion 310 may be provided with a curved surface 321 protruding toward the lens 200. For example, the curved surface 321 may be a conical surface, a cylindrical surface, or other types of curved surfaces. The curved surface 321 may contact the side of the lens 200 away from the positioning boss 130, which helps to achieve line contact at the connection between the curved surface 321 and the side of the lens 200 away from the positioning boss 130, thereby helping to reduce the risk of stress concentration at the contact point between the lens 200 and the curved surface 321, and further helping to reduce the risk of the lens 200 breaking, thereby extending the service life of the lens 200.

[0052] In some embodiments, the elastic pressing portion 320 may include an elastic arm 322 and a pressing plate 323, one end of the elastic arm 322 may be connected to the connecting portion 310, the other end of the elastic arm 322 may be connected to the pressing plate 323, and the curved surface 321 may be located on the pressing plate 323. The elastic arm 322 may be elastically deformed, and the elastic arm 322 may be bent in a specific direction relative to the connecting portion 310, for example, the elastic arm 322 may be bent from the connecting portion 310 to the end of the lens 200 abutting against the first supporting surface 110, thereby facilitating the elastic arm 322 to bring the curved surface 321 of the pressing plate 323 into close contact with the side of the lens 200 away from the positioning boss 130, thereby facilitating the elastic pressing portion 320 to be closely pressed against the side of the lens 200 away from the positioning boss 130.

[0053] The lens 200 may be located in the optical path of the emitted light of the light emitting assembly 400. There are many options for the lens 200, and the lens 200 may be a coated lens. Figure 5 In some embodiments, the lens 200 may include a coating portion 210. Since the coating portion 210 is coated with a film layer, the coating portion 210 can reflect or transmit the light emitted by the light emitting component 400. For example, the coating portion 210 can reflect at least one of red light, green light, blue light, etc. For another example, the coating portion 210 can transmit at least one of red light, green light, blue light, etc. For another example, the coating portion 210 can reflect at least one color of light and transmit at least one color of light.

[0054] See also Figure 2 , Figure 3 and Figure 5 The lens 200 may further include a first abutting portion 220 and a second abutting portion 230, and the coating portion 210 may be connected between the first abutting portion 220 and the second abutting portion 230. The coating portion 210 and the first abutting portion 220 may have a boundary or may not have a boundary. The coating portion 210 and the second abutting portion 230 may have a boundary or may not have a boundary. The center of the lens 200 may be located at the coating portion 210.

[0055] The position distribution of the coating portion 210, the first abutting portion 220 and the second abutting portion 230 may be different according to the shape of the lens 200. When the lens 200 is substantially square, for example, the lens 200 is substantially square or rectangular, the first abutting portion 220, the coating portion 210 and the second abutting portion 230 may be sequentially distributed along the length direction or the width direction of the lens 200. When the lens 200 is substantially circular or elliptical, the first abutting portion 220, the coating portion 210 and the second abutting portion 230 may be sequentially distributed along the radial direction of the lens 200.

[0056] The number of the positioning boss 130 and the elastic pressure piece 300 can be multiple. The first abutment portion 220 can be attached to a portion of the positioning surface 131 and abut against a portion of the elastic pressure piece 300, and the second abutment portion 230 can be attached to another portion of the positioning surface 131 and abut against another portion of the elastic pressure piece 300, thereby helping the lens 200 to be stably installed on the base 100 through the first abutment portion 220 and the second abutment portion 230.

[0057] In some embodiments, when the first abutment portion 220 (or the second abutment portion 230) cooperates with a positioning surface 131 and an elastic pressure member 300, the positioning surface 131 can be attached to the middle of the first abutment portion 220 (or the second abutment portion 230), and the elastic pressure member 300 can abut against the middle of the first abutment portion 220 (or the second abutment portion 230).

[0058] In some embodiments, when the first abutment portion 220 (or the second abutment portion 230) cooperates with two positioning surfaces 131 and an elastic pressure member 300, the two positioning surfaces 131 can be attached to the side or both sides of the middle of the first abutment portion 220 (or the second abutment portion 230), and the elastic pressure member 300 can abut against the middle of the first abutment portion 220 (or the second abutment portion 230).

[0059] In some embodiments, the coating portion 210 may be coated with a film layer that reflects the first wavelength and transmits the second wavelength, thereby helping the coating portion 210 to reflect both the first wavelength and the second wavelength. For example, the coating portion 210 may be coated with a green-transmitting and red-reflecting film layer, and the coating portion 210 may transmit green light and reflect red light. For another example, the coating portion 210 may be coated with a green-transmitting and blue-reflecting film layer, and the coating portion 210 may transmit green light and reflect blue light. For another example, the coating portion 210 may be coated with a red-transmitting, green-reflecting, blue-reflecting film layer, and the coating portion 210 may transmit red light and green light and reflect blue light. For another example, the coating portion 210 may be coated with a blue-transmitting, green-reflecting, red-reflecting film layer, and the coating portion 210 may transmit blue light and green light and reflect red light.

[0060] See also Figure 2 and Figure 3 The second support surface 120 may be provided with a light-avoiding through hole 140, and the light-avoiding through hole 140 may penetrate the second support surface 120, so as to facilitate the coating part 210 to receive light incident from the direction of the second support surface 120. For example, when the coating part 210 is coated with a film layer that reflects a first wavelength and transmits a second wavelength, the coating part 210 may reflect light incident from the direction of the second support surface 120 and transmit the outgoing light of the light-emitting component 400.

[0061] See also Figure 3 In some embodiments, the base 100 may be provided with a groove 150, and the groove 150 may be located at the connection between the first support surface 110 and the second support surface 120, and a gap 160 may be formed between the lens 200 and the second support surface 120 (see Figure 7 ), the gap 160 can be connected to the groove 150. In this way, the airflow inside the base 100 can flow to the gap 160 through the groove 150, which helps the airflow inside the base 100 to dissipate heat on the side of the lens 200 facing the second supporting surface 120, thereby helping to reduce the temperature of the lens 200, and further helping to extend the service life of the lens 200.

[0062] See also Figure 6 and Figure 7 In some embodiments, a gap 160 may be formed between the lens 200 and the second support surface 120, and the lens assembly 10 may further include an adhesive layer, which may be formed by an adhesive such as UV adhesive, instant adhesive, hot melt adhesive, or AB adhesive. The adhesive layer may be located in a portion of the gap 160, and the adhesive layer may be bonded to the lens 200 and the second support surface 120, which helps to reduce the risk of the lens 200 being easily separated from the base 100, thereby helping the lens 200 to be firmly mounted on the base 100, and further helping to improve the stability and firmness of the lens 200 mounted on the base 100. In addition, the adhesive layer may be located in a portion of the gap 160, thereby helping to reduce the risk of the gap 160 being completely blocked, thereby helping the airflow inside the base 100 to flow in the gap 160, so as to dissipate heat from the lens 200.

[0063] See also Figure 2 and Figure 3 In some embodiments, the bases 100 of two adjacent lens assemblies 10 may be integrally formed, thereby helping to reduce the assembly process of the light source device 20, thereby helping to improve the assembly efficiency of the light source device 20. In other embodiments, the bases 100 of two adjacent lens assemblies 10 may be connected by screw connection or welding connection.

[0064] The emitted light of the plurality of light emitting components 400 can be combined after being acted upon by the lenses 200 of the plurality of lens components 10. Figure 8 As shown, the number of the light emitting components 400 may be two, namely, the first light emitting component 400a and the second light emitting component 400b. The number of the lens components 10 may be two, namely, the first lens component 10a and the second lens component 10b, the first lens component 10a has a first lens 200a, and the second lens component 10b has a second lens 200b. Among them, the outgoing light of the first light emitting component 400a is reflected by the first lens 200a and the second lens 200b in sequence and then emitted, and the outgoing light of the second light emitting component 400b is emitted after passing through the second lens 200b. The outgoing light of the first light emitting component 400a is reflected by the first lens 200a and the second lens 200b in sequence, and the outgoing light of the second light emitting component 400b is emitted in parallel in the same direction, so as to help the light source device 20 to efficiently combine the outgoing light of the first light emitting component 400a and the outgoing light of the second light emitting component 400b.

[0065] For example, Fig. 9 As shown, the number of the light emitting components 400 can be three, namely, the first light emitting component 400a, the second light emitting component 400b and the third light emitting component 400c. The number of the lens components 10 can be three, namely, the first lens component 10a, the second lens component 10b and the third lens component 10c, the first lens component 10a has a first lens 200a, the second lens component 10b has a second lens 200b, and the third lens component 10c has a third lens 200c.
