Technical Field

[0001] The utility model relates to the technical field of COB modules, in particular to a COB module with a waterproof function. Background Art

[0002] The COB module is an emerging LED packaging technology.

[0026] Example

[0027] See also Figure 1-5The utility model provides a technical solution: a COB module with waterproof function, including a COB module body 1, an aluminum substrate 3 is arranged on one side of the COB module body 1, and a fixing frame 7 is integrally formed on one side of the aluminum substrate 3. The one side of the assembled COB module body 1 is connected to the aluminum substrate 3, and then waterproof glue is poured into the inner side of the glue pouring groove 5, and a glue pouring groove 5 is opened on one side of the fixing frame 7. A number of glue outlet holes 6 are arranged on the inner side of the glue pouring groove 5. Waterproof glue is poured into the inner side of the glue pouring groove 5 and the glue outlet holes 6. The waterproof glue flows from the glue outlet holes 6 on the inner side of the glue pouring groove 5 to one side of the COB module body 1. At this time, the aluminum substrate 3 is pasted on one side of the COB module body 1 by the waterproof glue, and the outer side of the COB module body 1 is bonded to one side of the aluminum substrate 3 by the waterproof glue. A power interface 4 is installed on one side of the aluminum substrate 3, and the output end of the power interface 4 is electrically connected to the input end of the COB module body 1. There are two power interfaces 4, and a protective component 2 is arranged on one side of the COB module body 1.

[0028] In order to prevent the COB module body 1 from being damaged by the impact of external objects, a protective component 2 is provided. The protective component 2 includes a mounting frame 21. A warning light 22 is installed on one side of the mounting frame 21. Four slide grooves 27 are provided inside the mounting frame 21. When an external object hits one side of the push plate 24, the push plate 24 pushes the slide column 23 and the slide plate 26 to move accordingly. At this time, the slide plate 26 compresses the spring 28. The force of the external impact is converted into the compression force of the spring 28 through the compression of the spring 28. The slide plate 26 is slidably connected to the inner side of the slide groove 27. Switches 210 are fixed to the inner side walls of the four slide grooves 27. The output end of the switch 210 is electrically connected to the input end of the warning light 22. A plurality of through holes 25 are provided on one side of the slide plate 26. A plurality of slide columns 23 are fixed on one side of the slide plate 26. The push plate 24 can push the slide column 23 and the slide plate 26 to move and compress the spring 28, so as to absorb and disperse the impact force, reduce the impact force directly acting on the COB module body 1, and thus protect the COB module body 1 from damage.

[0029] In order to alert nearby staff after an external object hits, the outer side of the sliding column 23 moves through one side of the mounting frame 21. When the external object hits with a large force, the sliding plate 26 will hit one side of the switch 210. When the switch 210 is triggered, the warning light 22 will produce sound and light prompts. A push plate 24 is fixed to one end of several sliding columns 23. A spring 28 is connected between one side of the sliding plate 26 and the inner wall of the slide groove 27. The inner wall of the slide groove 27 is fixed with limit blocks 29 located on both sides of the switch 210. When the sliding plate 26 hits the switch 210 and is triggered, the warning light 22 will emit sound and light prompts. The timely warning mechanism can actively inform nearby staff so that they can respond quickly to avoid further damage or safety accidents. The inner wall of the mounting frame 21 is fixed to the outer side of the COB module body 1.

[0030] Working principle: When the COB module body 1 is produced, one side of the assembled COB module body 1 is connected to the aluminum substrate 3, and then waterproof glue is poured into the inner side of the glue pouring groove 5. The waterproof glue flows to one side of the COB module body 1 through the glue outlet 6 on the inner side of the glue pouring groove 5. At this time, the aluminum substrate 3 is pasted to one side of the COB module body 1 through the waterproof glue, and the external power plug is inserted into the inner side of the power interface 4, so that the COB module body 1 can work. At the same time, the waterproof glue is used to seal the COB module body 1 and the aluminum substrate 3 around. The pouring and flowing of the waterproof glue can ensure that the connection between the COB module body 1 and the aluminum substrate 3 is well sealed, effectively preventing the intrusion of moisture or other liquids, thereby significantly enhancing the waterproof performance of the COB module body 1 lamp, reducing the risk of electrical short circuit or leakage caused by moisture intrusion, and thus improving the electrical safety of the lamp.

[0031] When the COB module body 1 is in use, an external object hits one side of the push plate 24. At this time, the push plate 24 pushes the sliding column 23 and the slide plate 26 to move with it. At this time, the slide plate 26 compresses the spring 28. Through the compression of the spring 28, the force of the external impact is converted into the compression force of the spring 28. When the impact force of the external object is large, the slide plate 26 will hit one side of the switch 210. When the switch 210 is triggered, the warning light 22 will produce sound and light prompts to actively inform nearby staff. At this time, the outer side of the COB module body 1 is hit by an external object. When the external object hits the push plate 24, the push plate 24 can push the sliding column 23 and the slide plate 26 to move and compress the spring 28, which can absorb and disperse the impact force, reduce the impact force directly acting on the COB module body 1, thereby protecting the COB module body 1 from damage. When the impact force is large, the slide plate 26 hits the switch 210 and is triggered, and the warning light 22 will emit sound and light prompts. The timely warning mechanism can actively inform nearby staff so that they can respond quickly to avoid further damage or safety accidents.
