DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the utility model.

[0023] See also Figure 1 and Figure 2 The embodiment of the present invention provides a light source module 10. The light source module 10 can be used for machine vision lighting; or, the light source module 10 can be used for stage lighting.

[0024] The light source module 10 includes a shell 100, a light source assembly 200, a light guide 300 and an elastic locking mechanism 400. The shell 100 is provided with a light exit hole 110; the light source assembly 200 is installed in the shell 100 and is used to generate output light; the light guide 300 is arranged in the shell 100 and is located in the optical path of the output light of the light source assembly 200. The output light of the light source assembly 200 is transmitted through the light guide 300 and then emitted from the light exit hole 110 to the outside of the shell 100; the elastic locking mechanism 400 is located in the shell 100, and the elastic locking mechanism 400 and the shell 100 jointly elastically press the light guide 300 to limit the movement of the light guide 300. In this way, compared with the light source module in the related art, the light source module 10 of the present application elastically presses the light guide 300 together with the shell 100 through the elastic locking mechanism 400, avoiding damage or breakage of the light guide 300 that may be caused by rigid fixing methods such as screws, thereby helping to extend the service life of the light guide 300 and enable the light guide 300 to maintain good optical performance.

[0025] In addition, when the light source module 10 is subjected to an external collision, the elastic locking mechanism 400 can play a buffering role and absorb part of the energy of the collision, so that the light guide member 300 is not easily damaged.

[0026] Moreover, the light source assembly 200, the light guide 300 and the elastic locking mechanism 400 are all installed in the shell 100, which helps the shell 100 to protect components such as the light source assembly 200, the light guide 300 and the elastic locking mechanism 400, thereby helping to reduce the risk of dust, dirt or other debris entering the interior of the shell 100.

[0027] In some embodiments, the light source module 200 , the light guide 300 and the light exit hole 110 may be substantially on the same straight line, thereby facilitating the light emitted from the light source module 200 to be emitted from the light exit hole 110 to the outside of the housing 100 after propagating through the light guide 300 .

[0028] In some embodiments, the light source assembly 200 may include a light source and a light-collecting lens component. The light source, which may be an LED or laser, can generate emitted light when powered. The light-collecting lens component may include a convex lens, a concave lens, or a composite lens, and may be designed based on actual needs. The light-collecting lens component can concentrate the emitted light generated by the light source into a smaller area, thereby forming a more concentrated light beam.

[0029] The light source can generate outgoing light after being powered on, and the light-collecting lens component can focus the outgoing light of the light source into a more concentrated light beam. The light beam emitted from the light-collecting lens component is evenly treated by the light guide 300 and then emitted from the light output hole 110 to the outside of the light source module 10.

[0030] In some embodiments, the light guide 300 may be a light rod, which can be used to transmit and guide light to achieve efficient light transmission and uniform light distribution. The overall shape of the light guide 300 can be roughly cylindrical, and the light guide 300 can be made of a transparent material, such as glass or a transparent organic composite.

[0031] In some embodiments, the light guide 300 is cylindrical, and the side surface of the light guide 300 abuts against the inner surface of the housing 100. The housing 100 can limit the light guide 300 along the radial direction of the light guide 300, thereby helping to reduce the risk of the light guide 300 moving along its own radial direction.

[0032] In some embodiments, the light guide 300 includes a first end 310 and a second end 320 connected to each other, and the elastic locking mechanism includes an elastic locking structure 410 and a support structure 420. The support structure 420 abuts between the first end 310 and the light source assembly 200, and the elastic locking structure 410 elastically presses between the second end 320 and the housing 100. In this way, the support structure 420 can support the first end 310, and the elastic locking structure 410 can support the second end 320, so that the first end 310 and the second end 320 of the light guide 300 are both clamped between the elastic locking structure 410 and the support structure 420. The support structure 420 and the elastic locking structure 410 can limit the light guide 300 along its axial direction, thereby helping to reduce the risk of the light guide 300 moving along its own axial direction within the housing 100.

[0033] In addition, the elastic locking structure 410 has elastic properties, so that the elastic locking structure 410 can absorb part of the impact and vibration, thereby helping to reduce the external force transmitted to the light guide member 300.

[0034] In some embodiments, the elastic locking structure 410 includes an elastic member 411 and a first light-transmitting support member 412. The first light-transmitting support member 412 abuts between the elastic member 411 and the second end 320, and the elastic member 411 elastically presses between the housing 100 and the first light-transmitting support member 412. The shape of the elastic member 411 can avoid light processed by the light guide 300, allowing the light processed by the light guide 300 to pass through the first light-transmitting support member 412 and exit from the light exit hole 110 to the outside of the light source module 10. Thus, the first light-transmitting support member 412 is located between the elastic member 411 and the second end 320 of the light guide 300, allowing the first light-transmitting support member 412 to act as an intermediate layer, allowing the force applied by the elastic member 411 to be evenly transmitted to the light guide 300, thereby helping to reduce the risk of localized stress concentration caused by direct contact between the light guide 300 and the elastic member 411.

[0035] In some embodiments, the first light-transmitting support member 412 is a diffuser. Thus, the diffuser can evenly diffuse the optical fibers from the light guide 300, making the light emitted by the light source module 10 softer and more evenly distributed, thereby helping to reduce glaring bright spots or shadows generated by the light source module 10.

[0036] In some embodiments, the diffuser may be in contact with the end surface of the second end 320 of the light guide 300 , so that the diffuser can support the light guide 300 more stably.

[0037] In some embodiments, the elastic member 411 may be a spring. The spring is hollow, which helps the elastic member 411 deflect light processed by the light guide 300. This allows the elastic member 411 to have high elasticity and resilience, allowing it to quickly return to its original state after being compressed or stretched. This allows the elastic member 411 to continuously provide a stable pressing force against the light guide 300, ensuring the secure connection between the light guide 300 and other components.

[0038] In addition, the spring is usually made of metal material, so that the elastic member 411 has high durability and fatigue resistance, and can maintain a stable working state during long-term use.

[0039] In some embodiments, the elastic member 411 can be a silicone ring or a rubber ring. The interior of the silicone ring or the rubber ring is hollow, which helps the elastic member 411 to avoid light processed by the light guide 300. Due to the inherent softness and elasticity of the silicone ring or the rubber ring, the elastic member 411 quickly returns to its original state after being compressed, providing a continuous and stable compressive force.

[0040] In some embodiments, the support structure 420 includes a support frame 421 and a second light-transmitting support member 422, wherein the second light-transmitting support member 422 abuts between the first end 310 and the support frame 421, and the support frame 421 abuts between the second light-transmitting support member 422 and the light source assembly 200. The second light-transmitting support member 422 can be provided in a sheet-like shape and can be made of a transparent material such as glass or polymethyl methacrylate. The emitted light of the light source assembly 200 passes through the second light-transmitting support member 422 and enters the light guide 300. The interior of the support frame 421 can be hollow to avoid blocking the emitted light of the light source assembly 200. In this way, the support frame 421 and the second light-transmitting support member 422 work together to provide support for the first end 310 of the light guide 300.

[0041] In addition, the support frame 421 abuts between the second light-transmitting support member 422 and the light source assembly 200 , thereby helping to reduce the risk of the second light-transmitting support member 422 and the light source assembly 200 moving.

[0042] In some embodiments, the second light-transmitting support member 422 is spaced apart from and opposite to the light source assembly 200. Thus, the second light-transmitting support member 422 is spaced apart from the light source assembly 200, so that a certain space is formed between the second light-transmitting support member 422 and the light source assembly 200, thereby helping to reduce the risk of heat generated by the light source assembly 200 being directly transferred to the light guide member 300.

[0043] In some embodiments, the housing 100 includes a main body 120 and a cover 130, which together enclose a receiving space 140. The light source assembly 200, the light guide 300, and the elastic locking mechanism 400 are all installed in the receiving space 140, and the light outlet 110 is provided in the cover 130. In this way, the cover 130 and the main body 120 form a relatively closed receiving space 140, so that the cover 130 and the main body 120 can effectively protect internal components such as the light source assembly 200, the light guide 300, and the elastic locking mechanism 400 from the influence of the external environment (such as dust, moisture, pollutants, etc.).

[0044] In some embodiments, the cover 130 is detachably connected to the main body 120. For example, the cover 130 can be connected to the main body 120 by screws or snap-fit ​​connections. In this way, when the light source assembly 200, the light guide 300, or the elastic locking mechanism 400 needs to be maintained, inspected, or replaced, the operator can easily remove the cover 130 to inspect the light source assembly 200, the light guide 300, or the elastic locking mechanism 400.

[0045] In some embodiments, the cover 130 is threadedly connected to the main body 120, so that the cover 130 and the main body 120 can be tightly coupled, thereby preventing the cover 130 from loosening or falling off the main body 120. In addition, the threaded connection between the cover 130 and the main body 120 can effectively reduce the risk of accidental opening of the cover 130 due to external vibration, impact, or other external forces.

[0046] In some embodiments, the main body 120 includes a first housing 121 and a second housing 122. The first housing 121 is detachably connected between the cover 130 and the second housing 122. The cover 130, the second housing 122, and the third housing together enclose a receiving space 140. The first housing 121 and the second housing 122 can be heat dissipation housings or heat sinks, etc., so that the first housing 121 and the second housing 122 can dissipate heat generated by the light source assembly 10 to the outside of the housing 100.

[0047] Based on the above embodiment, the assembly process of the light source module 10 is as follows: first, the second light-transmitting support member 422 is installed on the support frame 421, and then the assembled second light-transmitting support member 422 and the support frame 421 are installed in the first shell 121, and then the light source assembly 200 is installed in the accommodating space 140, and then the second shell 122 is connected to the first shell 121, and finally, after the light guide member 300, the first light-transmitting support member 412 and the elastic member 411 are installed in the accommodating space 140, the cover body 130 and the first shell 121 are screwed together. At this time, the inner surface of the cover body 130 is in contact with the end of the elastic member 411 facing away from the first light-transmitting support member 412, and the elastic member 411 is compressed by continuously tightening the cover body 130. When the elastic member 411 is compressed to a certain amount, the first light-transmitting support member 412 and the light guide member 300 can be pressed and fixed. In this way, the elastic effect of the elastic member 411 can reduce damage to the light guide member 300 caused by vibration and other reasons during use of the light source module 10, thereby reducing the risk of quality damage to the light source module 10 during use.
