Description

Technical Field

[0001] The utility model relates to an LED lamp, in particular to an LED step lamp. Background Art

[0002] Step lights are a type of lighting fixture installed on outdoor steps. Traditional outdoor step lights generally use LED light strips, which are directly fixed and installed at the bottom of the edge of the step panel. Once the LED light strip is fixed and installed, it can only emit light at one angle, and the lighting angle of the LED light strip cannot be flexibly selected. The lighting is fixed, resulting in this type of outdoor step light being unable to meet the needs of large-scale illumination in different environments. To solve this technical problem, a variety of outdoor step lights that can adjust the lighting angle have appeared on the market, such as the utility model patent announced by China, "An outdoor adjustable angle modular step light" (authorization number CN212430676U), which includes a shell, a die-cast pipe joint, a fixing frame, a bracket, an LED board, a silicone pad, a power cord, a PC diffuser, a silicone strip, a light-emitting device, a screw hole, a groove, a second wall block, a rotating axis, a mounting hole, a first wall block, an LED lamp bead, a welding wire through hole, and a capacitor. The outer layer is composed of a shell on the light-emitting device, silicone pads at both ends of the shell, a fixing frame, and a die-cast pipe joint, and is fixedly mounted on the lower end plate of the bracket. The internal LED board provides a light source, and the characteristics of the PC diffuser make the irradiated light have good light transmittance. The rotating axis provided on the fixing frame is inserted into the groove on the die-cast pipe joint for fixing. The light-emitting device can rotate around the rotating axis to adjust the irradiation angle, and the upper end plate of the bracket can place the entire part in a suitable position in the irradiation environment. However, this step light has the following major problems: 1) Its rotating structure includes a fixing frame and a die-cast pipe joint, a rotating shaft is arranged in the middle of the outer end of the fixing frame, mounting holes are arranged at the four corners of the outer end of the fixing frame along the center of the rotating shaft, the fixing frame is fixedly connected to the two ends of the outer shell, a first wall block is arranged at both ends of the outer end of the fixing frame along the center of the rotating shaft and at both ends of the horizontal direction and the vertical direction, a groove for inserting the rotating shaft is arranged in the middle of the connecting end of the die-cast pipe joint and the fixing frame, and second wall blocks are evenly distributed in a ring along the center of the groove, the first wall block and the second wall block cooperate to leave a gap for the rotating shaft, this rotating structure is too complicated, resulting in increased cost; 2) The light-emitting device also includes an outer layer, the outer layer is composed of an outer shell, silicone pads at both ends of the outer shell, a fixing frame, and a die-cast pipe joint, and the assembly of the outer layer is relatively cumbersome. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an LED step lamp with a simple rotating structure.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an LED step lamp, composed of a bracket and a light-emitting device, the light-emitting device includes a lamp body, characterized in that: support arms are integrally extended forward on both sides of the front end of the bracket, and connecting plates are integrally extended downward on the opposite inner sides of the two support arms, the lamp body is limited between the two connecting plates, and a space is left between the end face of the lamp body facing the front end of the bracket and the front end of the bracket, and fasteners are used to pass through the connecting plates and the side walls of the lamp body on the same side to realize the connection between the bracket and the lamp body, and the lamp body is rotatable relative to the bracket.

[0005] A rubber gasket is arranged between the connecting plate and the side wall of the lamp body. The rubber gasket can increase the damping and friction between the connecting plate and the side wall of the lamp body, and can more conveniently adjust the lamp body to any angle.

[0006] The two side walls of the lamp body are provided with mounting holes, and the inner cavity of the lamp body is provided with a closed-end horizontal mounting column on the mounting hole, and the connecting plate is provided with a through hole, and the fastener passes through the through hole, the rubber gasket, and the mounting hole on the same side in sequence and is connected to the horizontal mounting column. Since the LED step lamp is used outdoors, a closed-end horizontal mounting column is provided to prevent rainwater or moisture from entering the lamp body through the mounting hole and causing a circuit short circuit or LED lamp bead failure.

[0007] After the lamp body is connected to the two connecting plates, the top of the lamp body is lower than the top surface of the bracket. After the LED step light is installed on the outdoor steps, the lamp body is usually located below the edge of the step panel. If the top of the lamp body is flush with the top surface of the bracket, the bracket cannot rotate. Therefore, the top of the lamp body needs to be lower than the top surface of the bracket. The greater the difference between the two, the greater the angle at which the lamp body can rotate.

[0008] The light emitting device further comprises a light source board and a diffusion board, a plurality of LED lamp beads are evenly mounted on the front of the light source board, a driving component and a soldering pad are mounted on the back of the light source board, one end of the external power line is electrically connected to the light source board through the soldering pad, the light source board is mounted in the inner cavity of the lamp body with the LED lamp beads facing downward, and the diffusion board is mounted on the bottom opening of the lamp body. The light emitting device of this structure is compact and small in size, suitable for step lamps, and the light source board and the diffusion board are easy to assemble and have no outer structure.

[0009] A threading hole for the external power cord to pass through is provided on the rear end face of the lamp body, and partition boards are provided on both sides of the threading hole in the inner cavity of the lamp body to horizontally partition the inner cavity of the lamp body. The space between the two partition boards forms an independent space. After one end of the external power cord passes through the threading hole, glue is poured between the two partition boards to seal the threading hole. By pouring glue between the two partition boards, not only can the threading hole be sealed, but also rainwater or moisture can be prevented from entering the lamp body through the threading hole to cause a short circuit or failure of the LED lamp bead, and the external power cord can be fixed to prevent the external power cord from being desoldered due to external force. In order to seal the threading hole after pouring glue between the two partition boards, the bottom position of the partition board is required to be lower than the position of the threading hole.

[0010] A vertical mounting column is arranged from top to bottom in the inner cavity of the lamp body, and the light source board is installed in the inner cavity of the lamp body by connecting with the vertical mounting column through fasteners. A step mounting surface is arranged circumferentially on the inner peripheral wall of the bottom opening of the lamp body, and the low surface of the step mounting surface is in the inner circle and the high surface is in the outer circle, so that a groove is formed between the inner peripheral wall of the bottom opening of the lamp body and the low surface of the step mounting surface, and the diffuser plate is installed on the low surface of the step mounting surface by gluing. In general, the vertical mounting columns are distributed on both sides of the lamp body; a step mounting surface is arranged circumferentially on the inner peripheral wall of the bottom opening of the lamp body, and the diffuser plate is installed on the low surface of the step mounting surface, which has low installation requirements; by gluing the diffuser plate, it is possible to prevent rainwater or moisture from entering the lamp body through the gap between the diffuser plate and the low surface of the step mounting surface, thereby causing a short circuit or failure of the LED lamp beads.

[0011] The front middle part of the bracket is integrally extended downward to be provided with a limit plate for limiting the installation position of the bracket. The setting of the limit plate not only facilitates the positioning and installation of the bracket, but also prevents the light emitting device from being too close to the step, thereby causing the lamp body to be unable to adjust the angle.

[0012] Reinforcing ribs are provided on both sides of the top surface of the bracket to reinforce the bracket and prevent the bracket from being deformed due to excessive force when adjusting the angle of the lamp body.

[0013] The bracket is provided with at least two different types of fixing holes, and different fixing holes can be selected for installation according to different installation objects.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1) By extending support arms forward on both sides of the front end of the bracket, a concave cavity is formed between the two support arms. After the lamp body is connected to the connecting plate through fasteners, the lamp body is located in the concave cavity, and a space is left between the end surface of the lamp body facing the front end of the bracket and the front end of the bracket. Therefore, the lamp body can rotate relative to the bracket around the fastener, thereby realizing flexible selection of the lighting angle.

[0016] 2) The fastener passes through the connecting plate to form a rotating structure. Compared with the existing step lamp, the rotating structure is very simple, and the rotation of the lamp body can be achieved by simply connecting the fastener to the lamp body, which is easy to assemble.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The directional position words such as "top", "bottom", "front", "back", and "down" described in the embodiments of the present invention are all relative, such as describing the directional position based on the state after being installed on the steps.

[0026] The utility model proposes an LED step lamp, as shown in the figure, which consists of a bracket 1 and a light-emitting device 2. The light-emitting device 2 includes a lamp body 21. The lamp body 21 is a rectangular parallelepiped structure. Support arms 11 are integrally extended forward on both sides of the front end of the bracket 1. Connecting plates 12 are integrally extended downward on the opposite inner sides of the two support arms 11. The lamp body 21 is limited between the two connecting plates 12. A space 3 is left between the end surface of the lamp body 21 facing the front end of the bracket 1 and the front end of the bracket 1. A fastener 41 is used to pass through the connecting plate 12 and the side wall of the lamp body 21 on the same side to realize the connection between the bracket 1 and the lamp body 21, and the lamp body 21 can rotate relative to the bracket 1. By extending support arms 11 forward on both sides of the front end of the bracket 1, a concave cavity 13 is formed between the two support arms 11. After the lamp body 21 is connected to the connecting plate 12 through the fasteners 41, the lamp body 21 is located in the concave cavity 13, and a space 3 is left between the end surface of the lamp body 21 facing the front end of the bracket 1 and the front end of the bracket 1. Therefore, the lamp body 21 can rotate relative to the bracket 1 around the fasteners, so that the lighting angle can be flexibly selected; the fasteners 41 pass through the connecting plate 12 to form a rotating structure, the structure is very simple, and the rotation of the lamp body 21 can be realized by simply connecting the fasteners 41 to the lamp body 21, which is easy to assemble.

[0027] A preferred solution is that a rubber gasket 5 is provided between the connecting plate 12 and the side wall of the lamp body 21 , and the rubber gasket 5 can increase the damping and friction between the connecting plate 12 and the side wall of the lamp body 21 , and can more conveniently adjust the lamp body 21 to any angle.

[0028] The preferred solution is that mounting holes 211 are provided on both side walls of the lamp body 21, and a horizontal mounting column 212 with a closed end is provided on the mounting hole 211 in the inner cavity of the lamp body 21, and a through hole 121 is provided on the connecting plate 12, and the fastener 41 passes through the through hole 121, the rubber gasket 5, and the mounting hole 211 on the same side in sequence and is connected to the horizontal mounting column 212. Since the LED step lamp is used outdoors, the horizontal mounting column 212 with a closed end is provided to prevent rainwater or moisture from entering the lamp body 21 through the mounting hole 211 and causing a circuit short circuit or LED lamp bead failure.

[0029] It is further defined that after the lamp body 21 is connected to the two connecting plates 12, the top of the lamp body 21 is lower than the top surface of the bracket 1. After the LED step light is installed on the outdoor steps, the lamp body 21 is usually located below the edge of the step panel. If the top of the lamp body 21 is flush with the top surface of the bracket 1, the bracket 1 cannot rotate. Therefore, the top of the lamp body 21 needs to be located lower than the top surface of the bracket 1. The greater the difference between the two, the greater the angle at which the lamp body 21 can rotate.

[0030] Specifically defined, the light emitting device 2 also includes a light source board 22 and a diffusion board 23. Several LED lamp beads 221 are evenly installed on the front of the light source board 22 to achieve a better lighting effect. A driving component 222 and a soldering pad 223 are installed on the back of the light source board 22. One end of the external power line 6 is electrically connected to the light source board 22 through the soldering pad 223. The light source board 22 is installed in the inner cavity of the lamp body 21 with the LED lamp beads 221 facing downward. The diffusion board 23 is installed on the bottom opening of the lamp body 21. The light emitted by the LED lamp beads 221 is irradiated to the external environment through the diffusion board 23. The light emitting device 2 of this structure is compact and small in size, and is suitable for step lights.

[0031] Specifically, a threading hole 213 for the external power cord 6 to pass through is provided on the rear end surface of the lamp body 21, and partition plates 214 are provided on both sides of the threading hole 213 in the inner cavity of the lamp body 21 to horizontally partition the inner cavity of the lamp body 21. The space between the two partition plates 214 forms an independent space. After one end of the external power cord 6 passes through the threading hole 213, glue is poured between the two partition plates 214 to seal the threading hole 213. By pouring glue between the two partition plates 214, not only can the threading hole 213 be sealed, but also rainwater or moisture can be prevented from entering the lamp body 21 through the threading hole 213 to cause a short circuit or failure of the LED lamp bead 221, and the external power cord 6 can be fixed to prevent the external power cord 6 from being desoldered due to external force. In order to seal the threading hole 213 after glue is poured between the two partition plates 214, the bottom position of the partition plate 214 is required to be lower than the position of the threading hole 213.

[0032] Specifically, a vertical mounting column 215 is arranged from top to bottom in the inner cavity of the lamp body 21, and the light source panel 22 is installed in the inner cavity of the lamp body 21 by connecting with the vertical mounting column 215 through fasteners 42. A step mounting surface is arranged circumferentially on the inner peripheral wall of the bottom opening of the lamp body 21, and the low surface 216 of the step mounting surface is in the inner circle and the high surface 217 is in the outer circle, so that a groove is formed between the inner peripheral wall of the bottom opening of the lamp body 21 and the low surface 216 of the step mounting surface, and the diffuser plate 23 is installed on the low surface 216 of the step mounting surface by gluing. Generally, the vertical mounting posts 215 are distributed on both sides of the lamp body 21; a step mounting surface is circumferentially arranged on the inner peripheral wall of the bottom opening of the lamp body 21, and the diffuser plate 23 is installed on the low surface 216 of the step mounting surface, and the installation requirements are not high; the diffuser plate 23 is installed by gluing, which can prevent rainwater or moisture from entering the lamp body 21 through the gap between the diffuser plate 23 and the low surface 216 of the step mounting surface and causing a short circuit or failure of the LED lamp bead 221.

[0033] The preferred solution is that a limit plate 14 is integrally extended downward from the front middle of the bracket 1 to limit the installation position of the bracket 1. The setting of the limit plate 14 not only facilitates the positioning and installation of the bracket 1, but also prevents the light emitting device 2 from being too close to the step, thereby preventing the lamp body 21 from being unable to adjust the angle.

[0034] A preferred solution is that reinforcing ribs 15 are provided on both sides of the top surface of the bracket 1 to reinforce the bracket 1 and prevent the bracket 1 from deforming due to excessive force when adjusting the angle of the lamp body 21. The number and specific positions of the reinforcing ribs 15 can be determined according to the situation.

[0035] It is further defined that at least two different types of fixing holes 16 are provided on the bracket 1, and different fixing holes 16 can be selected for installation according to different installation objects.
