[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See attached document Figures 1-6 A high-efficiency heat dissipation ultra-high brightness linear light source includes a support frame 1, a heat sink 2 slidably mounted on the top of the support frame 1, side plates 3 mounted on both sides of the surface of the heat sink 2, a light-transmitting plate 4 mounted on the top of the side plates 3, heat dissipation fins 5 mounted on the bottom of the heat sink 2, a mounting frame 6 provided on the top of the support frame 1, a fan body 7 mounted in the inner cavity of the mounting frame 6, a substrate 8 mounted on the top of the heat sink 2, a light guide rod 9 provided on the top of the substrate 8, a reflector cup 10 provided on the top of the substrate 8, and a limiting device provided on the inner side of the reflector cup 10. The heat sink 2 has an adjustment mechanism on its top, which can clamp and restrict the light guide rod 9 through the limiting mechanism. The light guide rod 9 can be installed, and its position can be adjusted through the adjustment mechanism. This allows the light spot to be adjusted by adjusting the position of the light guide rod 9. When the device is used for illumination, the fan body 7 blows air to remove the heat from the heat sink 2 and the heat dissipation fins 5, thereby cooling the device. It is worth noting that the light guide rod 9 is tapered, which allows for the adjustment of the light spot.

[0021] In addition, snap-fit ​​brackets 17 are installed on both sides of the top of the support frame 1, and snap-fit ​​rails 18 are installed on the inner side of the heat sink 2. The snap-fit ​​brackets 17 and snap-fit ​​rails 18 are slidably connected, which allows the support frame 1 and the heat sink 2 to be connected.

[0022] See attached document Figures 1-6The limiting mechanism includes a limiting frame 11, which is located inside the reflector cup 10 and in front of the light guide rod 9. A movable frame 12 is provided inside the reflector cup 10, and a fixed plate 13 is provided inside the reflector cup 10. A spring 14 is installed on the front of the fixed plate 13, and the front end of the spring 14 is connected to the movable frame 12. This allows the fixed plate 13 to support the spring 14 by pressing it against the movable frame 12 after the spring 14 is installed. The movable frame 12 and the limiting frame 11 can cooperate to limit the light guide rod 9. Both the movable frame 12 and the limiting frame 11 have a bonding pad (not marked in the figure) installed on their inner sides. The bonding pad can be attached to the surface of the light guide rod 9 to limit the light guide rod 9 and prevent it from falling.

[0023] See attached document Figures 1-2 The bottom of the support frame 1 is equipped with a docking block 15, and both sides of the bottom of the mounting frame 6 are equipped with snap-fit ​​blocks 16. The snap-fit ​​blocks 16 and the docking blocks 15 are snap-fitted together, so that the docking blocks 15 and the snap-fit ​​blocks 16 can be used to install the mounting frame 6. The mounting frame 6 and the fan body 7 can be disassembled and replaced by separating the snap-fit ​​blocks 16 and the docking blocks 15.

[0024] Example 1 See attached document Figures 3-4 The adjustment mechanism includes a first movable frame 19, which is disposed inside the reflector cup 10. The light guide rod 9 is located inside the first movable frame 19. A first moving block 20 is installed in the inner cavity of the first movable frame 19. A first limiting plate 21 is installed inside the reflector cup 10. A first connecting frame 22 is installed on the front of the first moving block 20. The limiting frame 11 and the fixing plate 13 are installed inside the first movable frame 19, which can clamp and limit the light guide rod 9.

[0025] In addition, first toothed plates 23 are installed on both sides of the front of the first connecting frame 22, and a first support plate 24 is installed on the front side of the top of the heat sink 2. A first mounting rod 25 is rotatably installed on the front of the first support plate 24, and the back of the first mounting rod 25 extends through to the back of the first support plate 24. A first gear 26 is installed on the surface of the first mounting rod 25. The first gear 26 meshes with the first toothed plate 23, and a second gear 27 meshes with the inner side of the first gear 26. When the second gear 27 is rotated, the first gear 26 can be driven to rotate. When the first gear 26 rotates, it will drive the first toothed plate 23 to move. The first toothed plate 23 can drive the first connecting frame 22 to move, so that the first connecting frame 22 drives the first movable frame 19 to move up or down. The installed first limiting plate 21 can limit the movement distance of the first moving block 20 and can adjust the height of the light guide rod 9.

[0026] When the light guide rod 9 is brought close to the light source, the light spot formed by the light source on the large end face of the light guide rod 9 will become larger because it covers a larger area on the end face, which makes the physical size of the effective light-gathering area larger. However, the incident angle of the light emitted from the edge point of the light source when it enters the end face will increase, and the maximum adjustment distance will ensure that the incident angle does not exceed the receiving angle of the light guide rod 9 at that point. The receiving angle is determined by the material critical angle and the cone angle to avoid the light from not being effectively transmitted, which would lead to a decrease in collection efficiency and a deterioration in the uniformity of the light spot.

[0027] When the light guide rod 9 is far away from the light source, the light spot on the end face of the light source will become smaller, the physical size of the effective light-gathering area will decrease, the incident angle of the light from the light source when entering the end face will generally decrease, making it easier to meet the total internal reflection condition, the collection efficiency will usually be higher, and the light spot uniformity may be better. The longitudinal translation is essentially a trade-off between the effective area size, the incident angle and the total light flux collected, which changes the solid angle range of the light guide rod 9 receiving the light source.

[0028] Example 2 See attached document Figures 5-6 The adjustment mechanism includes a second movable frame 28, which is located inside the reflector cup 10. The light guide rod 9 is located inside the second movable frame 28. A second movable block 29 is installed in the inner cavity of the second movable frame 28. A third movable block 30 is installed inside the reflector cup 10, and the second movable block 29 and the third movable block 30 are slidably connected. A second connecting frame 31 is installed on the front of the second movable block 29. A limiting frame 11 and a fixing plate 13 are installed inside the second movable frame 28, which can clamp and limit the light guide rod 9.

[0029] In addition, a second support plate 32 is installed on the front side of the top of the heat sink 2. A second mounting rod 33 is rotatably installed on the front of the second support plate 32, and the back of the second mounting rod 33 extends through to the back of the second support plate 32. A third gear 34 is installed on the surface of the second mounting rod 33. A fourth gear 35 meshes with the inner side of the third gear 34. A lead screw 36 is installed on the back of the third gear 34. A threaded sleeve 37 meshes with the surface of the lead screw 36. A connecting plate 38 is installed on the outer side of the threaded sleeve 37, and the outer side of the connecting plate 38 is connected to the second movable frame 28. When the fourth gear 35 is rotated, the third gear 34 is driven to rotate. When the third gear 34 rotates, it drives the lead screw 36 to rotate. The lead screw 36 drives the connecting plate 38 to move through the threaded sleeve 37. When the connecting plate 38 drives the second movable frame 28 to move, it drives the fixed plate 13 and the limiting frame 11 to move, thereby adjusting the position of the light guide rod 9.

[0030] When the light guide rod 9 moves perpendicular to its axis, the spatial position covered by its large end face changes. The light that originally irradiated a certain position on the end face may no longer irradiate the end face after translation, or the position that was not irradiated before may now be irradiated.

[0031] After adjusting the light guide rod 9, if the light source is uniform, translating the light guide rod 9 will move the position of the "window" for collecting light. However, the total amount of light flux and the angular distribution collected may not change much. If the brightness distribution of the light source is uneven, translating the light guide rod 9 will align the entrance "window" with different areas of the light source, thereby significantly changing the light flux, light intensity distribution, and subsequent small-end output light spot characteristics of the light guide rod 9. In projection or lighting systems, translating the light guide rod 9 will change the position of the small-end output light spot on the target plane.

[0032] Working principle: Align the snap-fit ​​block 16 with the mating block 15. By moving the mounting bracket 6 and the fan body 7 upwards, the snap-fit ​​block 16 is inserted into the mating block 15. The fan body 7 and the mounting bracket 6 are then installed into the support frame 1. A quick-connect connector is installed on the external power cable of the fan body 7, allowing it to connect to the quick-connect connector of an external power source, thus providing power to the fan body 7. When installing the support frame 1 and the heat sink 2, align the snap-fit ​​bracket 17 with the snap-fit ​​rail 18, allowing the snap-fit ​​rail 18 to be installed into the snap-fit ​​bracket 17, thus assembling the support frame 1 and the heat sink 2. The fan body 7 is activated to blow air onto the heat dissipation fins 5. The blown air can remove the heat from the heat dissipation fins 5 and the heat dissipation shell 2, thereby helping the equipment to dissipate heat and preventing the equipment from overheating during long-term operation, which could affect the internal electrical components. When adjusting the light guide rod 9, an Allen wrench is inserted into the socket on the front of the adjustment mechanism. Turning the Allen wrench drives the adjustment mechanism, which in turn moves the fixing plate 13 and the limiting frame 11, thereby moving the light guide rod 9 and adjusting the light spot of the equipment.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
