Description

Technical Field

[0001] The utility model relates to an LED lamp holder, in particular to a high-intensity LED lamp holder. Background Art

[0002] A lamp holder, in a broad sense, includes the lamp holder for mounting the light source, a power cord, a reflector (optional), and the light source. High-power light sources also require a heat sink for the lamp holder, while low-power light sources generally do not require a heat sink. Currently, LED light sources are primarily used, which offer advantages such as long life, high energy efficiency, high luminous efficiency, and good heat dissipation.

[0003] A type of recessed lamp holder is commonly installed on the ground in roads, parks, or squares for auxiliary lighting or decorative purposes. Because these lamp holders are installed outdoors and are easily damaged by vehicles, they require high strength and good water resistance. Consequently, these recessed lamp holders are difficult to remove after installation. Over time, many lamps fail to illuminate, affecting both aesthetics and lighting performance. Summary of the Invention

[0004] The utility model provides a high-intensity LED lamp holder, which solves the problem in the prior art that embedded lamp holders are difficult to disassemble.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a high-intensity LED lamp holder, comprising an embedded lamp holder, an LED light strip, a reflector and a lamp cover, wherein the embedded lamp holder is a coverless cylindrical structure, an opening edge of which is formed with an outer flange, the upper surface of the outer flange is provided with a positioning protrusion protruding upward, the bottom of the embedded lamp holder is provided with a positioning column protruding vertically upward, a screw hole is provided in the positioning column, and a first threading hole is provided on the embedded lamp holder; the reflector is an annular structure as a whole and is fixed in the embedded lamp holder, the reflector is composed of a reflective bottom plate, a reflective inner plate and a reflective outer plate, the LED light strip is fixed on the reflective bottom plate, and the reflector is provided with a second threading hole Through hole; the lamp cover is a hemispherical shell structure with an opening facing downward, the outer diameter of its lower edge is larger than the outer diameter of the outer flange, and a flange embedding groove consistent with the contour of the outer flange is provided on the bottom surface of the lamp cover, the depth of the flange embedding groove is less than or equal to the thickness of the outer flange, and a positioning groove adapted to the positioning protrusion is provided on the top of the flange embedding groove, a plurality of light-transmitting holes are opened on the lamp cover, a light-transmitting cover is fixedly attached to the inner wall of the lamp cover, a step hole is provided on the top of the lamp cover, and a screw is connected between the step hole and the screw hole; a power cord is connected to the LED light strip, and the power cord passes through the second wire threading through hole and the first wire threading through hole in sequence, and the excess length of the power cord is stored at the bottom of the embedded lamp holder.

[0006] The embedded lamp holder of the present invention is fixed to the ground, and screws tightly connect the lamp cover and the embedded lamp holder. The screws only have a tightening effect. The flanged embedded groove on the lamp cover cooperates with the flange to limit horizontal movement, and the positioning groove cooperates with the positioning protrusion to limit circumferential rotation. Since the outer wall of the lamp cover is a smooth curved surface, the lamp cover is not subjected to a large upward pulling force, so the tightening force of the screws is sufficient to ensure that the lamp cover and the embedded lamp holder fit tightly. At the same time, the opening of the external matching seam of the lamp cover and the embedded lamp holder is set vertically downward, which has a certain water-proof effect. The light-transmitting cover fits with the inner wall of the lamp cover and also has a certain waterproof effect. The embedded lamp holder and lamp cover of the present invention can be made of stainless steel or aluminum alloy, and the main body shape is obtained by a process of first stretching and then machining, which makes the present invention have excellent compressive strength.

[0007] The installation method of the present invention is as follows: a wire tube is laid at the bottom of the hardened ground in advance, and a mounting hole is left at a predetermined position, the hole diameter of which is slightly larger than the outer diameter of the embedded lamp holder. After the power cord is connected to the buried wire in the wire tube, an adhesive is placed in the mounting hole, generally cement mortar, and then the embedded lamp holder is placed in the mounting hole, with the bottom of the outer flange abutting against the surface of the hardened ground.

[0008] Furthermore, an anti-dropping convex ring is provided on the outer wall of the embedded lamp holder, which can be engaged with the cured adhesive and is not easy to loosen later.

[0009] Furthermore, the light shield is a hemispherical shell structure, with a rubber gasket sandwiched between the upper surface of the outer flange and the bottom of the light shield. This creates a water-permeable gap between the light shield and the lamp cover, thus preventing water from penetrating the interior of the present invention. The rubber gasket also provides preload, ensuring a tight fit between the light shield and the lamp cover.

[0010] Furthermore, the step hole is filled with hot melt sealant. There is also the possibility of water seepage between the step hole and the screw, so the hot melt sealant is filled to achieve a sealing effect. At the same time, the hot melt sealant will soften when heated, which will not affect the later disassembly.

[0011] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention can be quickly disassembled by unscrewing the screws, and has sufficient waterproofness, high overall structural strength, and excellent compressive strength.

[0019] Example 1: See Figure 1 and Figure 2 A high-intensity LED lamp holder includes an embedded lamp holder 10, an LED light bar 20, a reflector 30 and a lamp cover 40. The embedded lamp holder is a coverless barrel structure with an outer flange 11 formed on the opening edge. The upper surface of the outer flange is provided with four positioning protrusions 12 (see Figure 4 ), the positioning protrusion is truncated cone-shaped, a positioning column 13 protruding vertically upward is provided at the bottom of the embedded lamp holder, a screw hole 14 is provided in the positioning column, and a first threading hole 15 is provided on the embedded lamp holder; the reflector is annular in structure as a whole and is fixed in the embedded lamp holder, the reflector is composed of a reflective bottom plate 31, a reflective inner plate 32 and a reflective outer plate 33, the LED light bar is fixed on the reflective bottom plate, and a second threading hole 34 is provided at the bottom of the reflective inner plate 32; the lamp cover is a hemispherical shell structure with an opening facing downward, the outer diameter of its lower edge is larger than the outer diameter of the outer flange, a flange embedding groove 41 is provided on the bottom surface of the lamp cover in line with the contour of the outer flange, the depth of the flange embedding groove is equal to the thickness of the outer flange, a positioning groove 42 adapted to the positioning protrusion is provided on the top of the flange embedding groove, and four light-transmitting holes 43 are opened on the lamp cover (see Figure 3 ), a light-transmitting cover 50 is fixedly attached to the inner wall of the lamp cover, a step hole 44 is provided on the top of the lamp cover, and a screw 45 is connected between the step hole and the screw hole; a power cord is connected to the LED light bar, and the power cord passes through the second threading hole and the first threading hole in sequence, and the excess length of the power cord is stored at the bottom of the embedded lamp holder.

[0020] The recessed lamp holder of this embodiment is fixed to the ground. Screws securely connect the lamp cover and recessed lamp holder. The screws only provide tension. The flanged recesses on the lamp cover cooperate with the flanges to limit horizontal movement, while the positioning grooves and positioning protrusions cooperate to limit circumferential rotation. Because the outer surface of the lamp cover is a smooth curved surface, it is not subject to significant upward tension, so the tightening force of the screws is sufficient to ensure a tight fit between the lamp cover and the recessed lamp holder. Furthermore, the opening of the external mating seam between the lamp cover and the recessed lamp holder is vertically downward, providing a certain degree of water resistance. The light shield mates with the inner wall of the lamp cover, also providing a certain degree of waterproofing. The recessed lamp holder and lamp cover of this embodiment are made of stainless steel, and the main body is formed by a process of first stretching and then machining, which gives this embodiment excellent compressive strength.

[0021] See Figure 5 The installation method of this embodiment is as follows: a wire tube is laid at the bottom of the hardened ground in advance, and a mounting hole is left at a predetermined position. The hole diameter is slightly larger than the outer diameter of the embedded lamp holder. After connecting the power cord to the buried wire in the wire tube, an adhesive is placed in the mounting hole, generally cement mortar, and then the embedded lamp holder is placed in the mounting hole, with the bottom of the outer flange abutting against the surface of the hardened ground.

[0022] See Figure 1 The outer wall of the embedded lamp holder is convexly provided with an anti-dropping convex ring 16. The anti-dropping convex ring can be engaged with the cured adhesive and is not easy to loosen in the later stage.

[0023] See Figure 1 A limiting step 17 is provided on the inner wall of the embedded lamp holder. The reflector further includes a plug sleeve 35 integrally provided with the reflective outer plate. The bottom of the plug sleeve abuts against the limiting step, and the outer wall of the plug sleeve fits with the inner wall of the embedded lamp holder.

[0024] See Figure 1 The light shield is a hemispherical shell structure, with a rubber gasket sandwiched between the upper surface of the outer flange and the bottom of the light shield. A water-permeable gap is formed between the light shield and the lamp cover, so the rubber gasket prevents water from penetrating the interior of this embodiment. The rubber gasket also provides preload, ensuring a tight fit between the light shield and the lamp cover.

[0025] See Figure 1 , the step hole is filled with hot melt sealant 60. There is also the possibility of water seepage between the step hole and the screw, so it is sealed by filling with hot melt sealant. At the same time, the hot melt sealant will soften when heated and will not affect the later disassembly.

[0026] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
