Waterproof LED lamp housing

The invention relates to an LED lamp housing, in particular to an LED lamp housing for waterproof function.

As the luminous efficiency of LEDs increases, LEDs gradually replace traditional light bulbs and are used in various indoor lighting equipments, and are also used in outdoor lighting. However, because LEDs have low tolerance to humidity, waterproofing of lamps is quite equivalent for LEDs. important.

Therefore, the prior art provides an LED lamp housing, as shown in FIG. 7, which includes a cover body 70, a body 71 and a waterproof rubber strip 72. The inner side of the side plate 701 of the cover body 70 is provided with an internal thread 702. A ring convex plate 711 is protruded upwardly from the upper end of the protrusion 71. The outer side of the ring convex plate 711 is provided with an external thread 712. The external thread 712 is opposite to the internal thread 702. The waterproof rubber strip 72 is embedded on the upper end of the body 71, and the waterproof rubber strip 72 is disposed on the ring convex portion. The outer side of the plate 711 is engaged with the external thread 712 of the body 71 by the internal thread 702 of the cover body 70 to screw the cover body 70 and the body 71, and the waterproof rubber strip 72 is pressed to make the cover body 70 and the body 70. There is no gap between the 71, and the waterproof effect is achieved.

However, the prior art LED lamp housing, which is screwed and compressed by the internal thread 702 and the external thread 712, can effectively and ensure the waterproof performance, but the bottom end of the external thread 712 and the body 71 When there is no space between the top side surfaces, when the cover body 70 and the body 71 are screwed, it is difficult to clearly know the distance between the bottom side surface of the cover body 70 and the top side surface of the body 71, and thus the compression amount of the waterproof rubber strip 72 cannot be known. The compression amount of the waterproof strip 72 is difficult to control, and if the amount of compression is too small, the waterproofness is poor, and if it is to be ensured The waterproof property is easy to be excessively compressed, so that the waterproof rubber strip 72 is elastically fatigued, aged or chipped, thereby shortening the service life of the waterproof rubber strip 72 and affecting the waterproof property.

In view of the above-mentioned shortcomings of the prior art, the present invention provides an LED lamp housing with waterproof function, which can effectively control the compression amount of the waterproof rubber strip, and achieve the requirement of not reducing the service life of the waterproof rubber strip and good waterproof performance.

At the lower end, each of the top waterproof strips 25 is embedded in each of the ring grooves 211, and the bottom waterproof strip 26 is embedded outside the connecting ring 24.

Referring to FIG. 2, FIG. 4A and FIG. 4B, each of the bonding groups 30 is disposed between the cover 10 and the body 20 so that the cover 10 and the body 20 are spaced apart. The conjugates 30 are detachably coupled to each other, and each of the coupling groups 30 includes a protrusion 31 and a guide groove 32. The protrusion 31 is convexly formed on the inner wall surface of the side plate 12 of the cover 10. The protrusion 31 is disposed on the corresponding guide. In the groove 32, the guiding groove 32 is concavely formed on the outer wall surface of the annular convex plate 22 of the body 20, and the guiding groove 32 is opposite to the protruding post 31; as shown in FIG. 3 together, the guiding groove 32 is formed by a guiding hole end. The positioning end 322 of the positioning end 322 and the feeding portion 323 is disposed at the top surface of the guiding groove 32 and the annular convex plate 22, and the positioning end 322 is disposed at the top surface 21 of the guiding groove 32 near the body 20. The feeding portion 323 is connected between the guiding hole end 321 and the positioning end 322, and a rib 324 is convexly formed at the joint of the feeding portion 323 and the positioning end 322.

Referring to FIG. 5, another preferred embodiment of the present invention includes a cover body 10, a body 20 and at least one combination group 30a. Each of the combination groups 30a includes a protrusion 31a and a guide groove 32a. 31a is disposed in the corresponding guiding groove 32a, and the protruding post 31a is convexly formed on the outer wall surface of the annular convex plate 22 of the body 20, and the guiding groove 32a is concavely formed on the inner wall surface of the side plate 12 of the cover body 10, The guide hole end 321a is disposed at a joint of the lower end surface of the guide groove 32a and the side plate 12, and the positioning end 322a is disposed at a bottom end of the guide groove 32a near the top surface 11 of the cover body 10.

As shown in FIG. 2, since the body 20 is a hollow cylinder, an LED lamp group 40 can be disposed therein, and a lamp cap 50 is disposed at a lower end of the body 20. The upper end of the body 20 is open to allow the light emitted by the LED lamp group 40 to pass through. The transparent portion 11 of the cover 10 allows light that is opened through the upper end of the body 20 to penetrate.

Referring to FIG. 4A and FIG. 4B , the protrusions 31 of each combination group 30 are respectively embedded in the guide holes 321 of the corresponding guide grooves 32 , and pass through the feeding portion 323 and pass through the ribs 324 to reach the positioning end 322 . And stuck in the rib 324 Between the positioning end 322 and the body 10, the cover 10 is fixed to the top waterproof strip 24 in each ring groove 211 of the body 20, thereby achieving the waterproof effect. And a distance between the lowermost end of the positioning end 322 of the guiding groove 32 and the top surface 21 of the body 20 is fixed, so that the distance is fixed each time the cover 10 presses the top waterproof strips 25 in the ring grooves 211. The pressure applied by the cover 10 to each of the top waterproof strips 25 is fixed, so that the compression amount of each of the top waterproof glues 25 in each ring groove 211 is fixed, thereby effectively controlling the waterproof LED lamp housing of the present invention. The feed stroke avoids excessive compression of the top waterproof strips 25, which causes the top waterproof strips 25 to age, embrittle or rupture, and the service life to be reduced, and the compression of each top waterproof strip 25 is not sufficient. The result is that the waterproof performance is not good, and the waterproof performance can be enhanced.

On the other hand, after the protrusions 324 of the bonding groups 30 enter the guiding groove 32 and reach the positioning end 322, the protruding post 31 can be clamped between the positioning end 322 and the protruding strip 324, thereby preventing The stud 31 is loosened by the guide groove 32, and the stud 31 is surely positioned at the positioning end 322 of the guide groove 32.

On the other hand, referring to FIG. 1 , FIG. 4A and FIG. 4B , since the stroke of the feed can be effectively controlled, the rotation amount of the cover 10 can be controlled, so that the ribs 121 of the cover 10 can be made. When the heat dissipation strips 23 of the main body 20 are aligned with each other, the gap between the adjacent ribs 121 is also aligned with the gap between the adjacent heat dissipation strips 23, so that the thermal resistance on the heat conduction path is reduced, thereby achieving the effect of enhancing heat dissipation.

On the other hand, as shown in FIG. 2 and FIG. 6 , when the lamp cap 50 is coupled with the lamp holder 60 , there is a gap between the connecting ring 24 of the body 20 and the lamp holder 60 , and the bottom waterproof rubber strip 26 and the connecting ring are connected. The gap between the 24 and the lamp holder 60 can be filled, It can prevent water or other liquid from flowing in through the gap and achieve the function of waterproofing.

On the other hand, when the cover 10 and the body 20 are combined by the bonding groups 30, there is still a slight gap between the lower end of the side panel 12 of the cover 10 and the top surface 21 of the body 20 and the top waterproof strips 25, The gap size cannot allow the liquid to pass through, but there is still air present in the gap, the heat resistance of the air is large, and the heat dissipation capability is poor; therefore, the heat-dissipating glue can be applied to the joint of the cover body 10 and the body 20, thereby enhancing heat dissipation.
