[0002] Surface mount LEDs, also known as SMD LEDs, are a simple type of light fixture. Their light-emitting principle is to pass an electric current through a compound semiconductor. Through the combination of electrons and holes, the excess energy is released in the form of light, thus achieving the effect of emitting light.
[0003] Existing surface mount LED lights typically use light guides to change the direction of the light, allowing the LED light to be displayed outside the device housing to form an indicator light. However, there is a lack of protective devices between the surface mount LED and the light guide, which can easily cause interference with the light guiding state of the light guide when there are foreign objects between them.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] See attached document Figure 1 - Appendix Figure 4 This utility model provides a protective structure for surface-mount LED lights in a device chassis, including a device housing 1, a PCB board body 2 inside the device housing 1, a light guide device body 3 on the top of the PCB board body 2, and a waterproof and dustproof device 4 between the PCB board body 2 and the light guide device body 3. The PCB board body 2 includes a PCB board 21, a fixed internal threaded sleeve 22 is inserted into the PCB board 21, and a surface-mount LED light 23 is fixedly mounted on the top of the PCB board 21. The light guide device body 3 includes a light guide post 31, a light guide indicator head 32 is fixedly mounted at one end of the light guide post 31, and a threaded end 33 is fixedly mounted at the bottom of the light guide post 31. The waterproof and dustproof device 4 includes a fixed cover 41, a movable sleeve 42 is fitted outside the fixed cover 41, a connecting ring 43 is fixedly fitted outside the movable sleeve 42, and a spring 44 is provided at the bottom of the connecting ring 43.
[0024] In this embodiment, in order to protect the SMD LED 23 from the light guide post 31 and prevent the light guide between the SMD LED 23 and the light guide post 31 from being blocked by impurities, when installing the light guide device body 3, the connecting ring 43 is first pressed down, so that the movable sleeve 42 slides down along the fixed cover 41, and the spring 44 is compressed at the same time. After the light guide device body 3 is installed in place, the connecting ring 43 is released, and the elastic force of the spring 44 causes the movable sleeve 42 to return to its original position. The top of the movable sleeve 42 contacts the bottom of the arc-shaped corner of the light guide post 31 of the light guide device body, thereby sealing the gap between the SMD LED 23 and the light guide post 31 of the light guide device body, achieving the purpose of waterproofing and dustproofing.
[0025] To achieve the purpose of fixing the light guide post 31, this device adopts the following technical solution: the fixing inner threaded sleeve 22 penetrates through the PCB board 21 and is fixedly connected to the PCB board 21; the PCB board 21 is fixedly connected to the device housing 1; one end of the light guide indicator head 32 penetrates through one side wall of the device housing 1 and extends out of the device housing 1; one end of the threaded end 33 extends into the interior of the fixing inner threaded sleeve 22 and is threadedly connected to the fixing inner threaded sleeve 22; the threaded end 33 of the light guide device body 3 is screwed into the fixing inner threaded sleeve 22 to achieve... The light guide device body 3 is fixedly connected to the PCB board body 2. Then, the PCB board body 2, the light guide device body 3, and the waterproof and dustproof device 4, which are assembled into one piece, are fixed on the equipment housing 1, so that one end of the light guide indicator head 32 extends out of the equipment housing 1 to form an indicator light. The light of the surface-mount LED light 23 passes through the light guide column 31, and the indicator color of the LED light can be seen from the surface of the housing. At the same time, a waterproof film can be attached to the light guide indicator head 32 on the surface of the equipment housing 1 to achieve the effect of light transmission and waterproofing.
[0026] To protect the light guiding state between the SMD LED 23 and the light guide post 31, the device employs the following technical solution: the bottom of the fixed cover 41 is fixedly connected to the top of the PCB board 21, and the fixed cover 41 is fitted over the SMD LED 23; the movable sleeve 42 is fitted over the fixed cover 41 and slidably connected to the fixed cover 41; the top of the spring 44 is fixedly connected to the bottom of the connecting ring 43, and the bottom of the spring 44 is fixedly connected to the top of the PCB board 21; the elasticity of the spring 44 causes the movable sleeve 42 to return to its original position upwards, and the top of the movable sleeve 42 contacts the bottom of the arc-shaped corner of the light guide post 31 of the main body of the light guide device, thereby sealing the gap between the SMD LED 23 and the light guide post 31 of the main body of the light guide device, achieving the purpose of waterproofing and dustproofing.
[0027] The usage process of this utility model is as follows: When using this utility model, first assemble the light guide device body 3 onto the PCB board body 2 (e.g., Figure 2 , 3With one hand, press down on the connecting ring 43. This causes the movable sleeve 42 to slide downwards along the fixed cover 41, and the pressing down of the connecting ring 43 causes the spring 44 to retract. With the other hand, hold the light guide device body 3 and screw it into the fixed inner threaded sleeve 22 through the threaded end 33. The light guide post 31 has a threaded end 33 at its bottom with a slot in the middle, allowing for quick assembly and fixation with the fixed inner threaded sleeve 22 in the PCB board 21. The slotted stud, after being inserted into the PCB, will expand and fix itself to the PCB to prevent loosening. This securely connects the light guide device body 3 to the PCB board 21. Then, release the connecting ring 43, and the retracted... Spring 44 causes connecting ring 43 to drive movable sleeve 42 to return upward, thereby making the top of movable sleeve 42 contact the bottom of the arc corner of light guide post 31, thus protecting the surface-mount LED 23, achieving the purpose of waterproofing and dustproofing, preventing the light emitted by surface-mount LED 23 from being blocked by impurities, and enabling light guide post 31 to stably guide the light emitted by surface-mount LED 23. Then, the PCB board body 2, light guide device body 3, and waterproof and dustproof device 4, which are assembled into one piece, are fixed on the equipment housing 1, so that one end of the light guide indicator head 32 extends out of the equipment housing 1 to form an indicator light.
