[0030] Embodiment 1 of the present utility model is a lamp assembly structure, as Figure 1 and Figure 2As shown in the figure, it includes a housing 1, an inner housing 2 and a buckle 3. The inner housing 2 is installed inside the housing 1, and the buckle 3 is arranged on the outside of the housing 1. A through hole 11 is provided on the side wall of the housing 1, and the buckle 3 passes through the through hole 11 and is snap-fitted and fixed to the inner housing 2.
[0031] As Figure 1 , Figure 2 and Figure 5 shown in the figure, two through holes 11 that horizontally penetrate the side wall are provided on the side wall of the housing 1. The two through holes 11 are symmetrically arranged with respect to the diameter of the cross-section of the housing 1. The inner housing 2 is installed inside the housing 1. Two buckles 3 horizontally pass through the through holes 11 of the housing 1 from outside to inside and are snap-fitted and fixed to the inner housing 2. The number of buckles 3 is not limited here. The size of the inner housing 2 is not greater than that of the housing 1, and the material of the housing 1 is selected as aluminum with good heat dissipation performance.
[0032] In this utility model, by arranging the buckle 3 to pass through the through hole 11 of the housing 1 and be snap-fitted and fixed to the inner housing 2, the assembly process of the housing 1, the inner housing 2 and the buckle 3 is simplified, the stability of the production process of the assembly process is improved, the floating of the production efficiency caused by personnel fluctuations is reduced, the production cost is reduced, and the assembly accuracy and production efficiency are improved.
[0033] Furthermore, as Figure 3 shown in the figure, the buckle 3 includes an assembly buckle position 31, a spring 32 and an assembly end 33 arranged in sequence. The assembly buckle position 31 is snap-fitted to the inner housing 2. Align the assembly buckle position 31 with the through hole 11, press the assembly end 33, so that the assembly buckle position 31 passes through the through hole 11, and use the elasticity of the spring 32 to snap the assembly buckle position 31 into the inner housing 2 to complete the assembly of the housing 1, the inner housing 2 and the buckle 3. Grooves and protrusions conducive to snap-fitting are provided on the assembly buckle position 31, and grooves or protrusions conducive to machine pressing can also be provided on the assembly end 33. The material of the assembly end 33 is plastic, and can also be other materials such as rubber and metal, as long as it is convenient for machine pressing. The material of the spring 32 is metal such as stainless steel, alloy steel and titanium alloy that is not easy to break and has a long service life.
[0034] Furthermore, as Figure 4 shown in the figure, an installation groove 21 is provided on the side wall of the inner housing 2. The notch of the installation groove 21 faces the through hole 11, and the assembly buckle position 31 is snap-fitted to the installation groove 21. The installation groove 21 corresponds to the through hole 11 of the housing 1. The size of the installation groove 21 should not be less than that of the assembly buckle position 31, and the number of installation grooves 21 should be the same as the number of buckles 3. The protrusion on the assembly buckle position 31 is fixed to the barb of the installation groove 21 to complete the snap-fitting of the assembly buckle position 31 and the inner housing 2.
[0035] Furthermore, as Figure 4 and 5As shown in the figure, a limiting member 211 is provided on the installation groove 21, and the bottom of the limiting member 211 abuts against the top of the assembly buckle 31. The limiting member 211 is used to limit the clamping position of the assembly buckle 31. The shape of the limiting member 211 corresponds to the shape of the top of the assembly buckle 31. During the clamping process of the assembly buckle 31 and the installation groove 21, when the protrusion engages with the barb of the installation groove 21, the bottom of the limiting member 211 exactly fits completely with the top of the assembly buckle 31, thereby limiting the clamping depth of the assembly buckle 31 and the installation groove 21, preventing the clamping depth from being too large, which may cause the spring 32 to contact the outer shell 1 and affect the normal use of the buckle member 3.
[0036] Specifically, as Figure 3 shown, a sealing strip 311 is provided on the assembly buckle 31. The sealing strip 311 cooperates with the through hole 11, and the sealing strip 311 is made of rubber material. The sealing strip 311 uniformly and comprehensively wraps the assembly buckle 31. After the outer shell 1, the inner shell 2, and the buckle member 3 are clamped together, the sealing strip 311 fits tightly with the through hole 11, preventing dust from entering and also playing a role in preventing light leakage. The rubber increases the friction between the assembly buckle 31 and the through hole 11 and the installation groove 21, further strengthening the clamping stability.
[0037] Specifically, as Figure 6 shown, a card slot 12 is horizontally provided inside the outer shell 1, and a circle of uniformly shaped clamping blocks 22 is provided at the opening edge of the inner shell 2. These clamping blocks 22 are used to tightly abut against the corresponding card slots 12. The clamping blocks 22 are symmetrically distributed with respect to the diameter of the cross-section of the inner shell 2. The card slots 12 inside the outer shell 1 are also uniformly shaped. The clamping blocks 22 and the card slots 12 are clamped with each other to complete the assembly of the inner shell 2 and the outer shell 1, eliminating the need for screws and welding, and simplifying the assembly process of the inner shell 2 and the outer shell 1. During assembly, the position of the through hole 11 of the outer shell 1 needs to correspond to the position of the installation groove 21 of the inner shell 2 to prevent affecting the assembly of the buckle member 3.
[0038] Specifically, it further includes a wire (not shown in the figure). As Figure 6 shown, the outer shell 1 is provided with a wire passing hole 13 that horizontally penetrates the side wall, and the wire passes through the wire passing hole 13 and is inserted into the outer shell 1. The position of the wire passing hole 13 does not affect the through hole 11. The number of wire passing holes 13 is not limited here, as long as it can accommodate the wires required for the LED downlight. The wire is inserted into the outer shell 1 from the outside to the inside through the wire passing hole 13 and is connected to external structures such as the light-emitting component, supporting the normal operation of the LED downlight. The wire passing hole 13 and the wire provide a convenient channel for energy to enter the outer shell 1, simplifying the assembly process of the wire and the outer shell 1.
[0039] Further, a limiting tail clip (not shown in the figure) is provided on the wire. The limiting tail clip is snap-fitted to the wire passing hole 13. The shape and size of the limiting tail clip correspond to those of the wire passing hole 13. The material of the limiting tail clip is not limited herein, as long as it is durable and not easily deformed. During the process of inserting the wire into the housing 1 from the outside to the inside, when the wire reaches the appropriate insertion depth, the limiting tail clip is exactly fixed on the wire passing hole 13 of the housing 1 by means of a barb, restricting the insertion depth of the wire into the housing 1, preventing the insertion depth of the wire into the housing 1 from being too large or too small, which may affect the energy transmission. At the same time, it also simplifies the assembly process of the wire and the housing 1. The limiting tail clip is in close contact with the outer end of the wire passing hole 13, preventing dust and light leakage.
[0040] Embodiment 2 of the present utility model is an LED downlight, which includes a light-emitting component and also includes the above-mentioned lamp assembly structure. The light-emitting component is arranged in the inner housing 2.
[0041] The LED downlight includes a lamp assembly structure and a light-emitting component. The light-emitting component includes an LED lamp bead, a constant current driving power supply, a reflector cup, a lens, etc. The LED lamp bead converts electrical energy into light energy. The constant current driving power supply converts the input alternating current into stable direct current to ensure that the LED lamp bead operates under normal working voltage and current. The reflector cup redistributes and reflects the light emitted by the LED lamp bead to improve the light flux utilization rate and reduce glare. The lens optimizes the light distribution and lighting effect, making the light more uniform and soft. Each part works together to achieve the advantages of high efficiency, energy saving, environmental protection, and long service life.
[0042] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
