Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and more particularly to an LED lighting fixture. Background Technology
[0002] In recent years, LED lights have been widely used in the lighting field due to their advantages such as high efficiency and energy saving, rich colors and long lifespan, especially in the bedside lamp and ambient light market.
[0003] From a structural design perspective, traditional LED lights typically employ a cylindrical lamp housing and a cylindrical lamp panel for assembly. While this design fulfills the basic functional requirements of the light fixture to some extent, it also has significant drawbacks. The cylindrical lamp panel usually requires the use of flexible lamp posts for assembly, and the manufacturing cost of flexible lamp posts is relatively high, undoubtedly increasing the overall cost of the product. Furthermore, the installation and maintenance of flexible lamp posts are also relatively complex, further limiting their widespread application in the market.
[0004] Secondly, the light transmission effect of existing LED bedside lamps or ambient lights is not ideal. Most products use a simple lamp housing structure, and after the light is emitted from the LED beads, it is transmitted through the lamp housing, often resulting in uneven light transmission. For example, the light is stronger near the LED beads and weaker further away, leading to uneven brightness.
[0005] In view of the shortcomings of existing technologies, it is necessary to propose new technical solutions. Utility Model Content
[0006] This utility model provides an LED lamp, which aims to solve at least one of the technical problems existing in the prior art.
[0007] The technical solution of this utility model is an LED lamp, which includes: a bottom housing, a first housing connected upward to the edge of the bottom housing, a second housing connected to the top edge of the first housing, a top housing connected to the top of the second housing, and an LED lamp post. The LED lamp post includes a first lamp panel enclosed on all four sides and a second lamp panel connected to and enclosed at the top of the first lamp panel. The first lamp panel and the second lamp panel are provided with a plurality of LED beads and a plurality of light sensors are arranged at intervals. The LED beads and the light sensors are electrically connected to a controller. The distance between the light sensors on the first lamp panel and the corresponding first and second housings is the same, and the distance between the light sensors on the first lamp panel and the corresponding top housings is the same. When the LED beads illuminate the second housing and the top housing, the second housing and the top housing reflect part of the light onto the light sensors, so as to allow the controller to output an independent control signal to control the LED beads to turn on and off.
[0008] Furthermore, it also includes: a mounting base, the center of which is connected to the inner surface of the bottom housing via a connecting portion; the bottom housing is provided with a plurality of first through holes around the perimeter of the mounting base; a first gap is provided between the perimeter of the mounting base and the bottom housing; a second through hole is provided at the base of each first lamp plate from the outside to the inside; a plurality of third through holes are provided on the second lamp plate; and a fourth through hole is provided around the perimeter of the top housing; wherein the first through holes, the first gap, the second through holes, the third through holes, and the fourth through holes are connected sequentially from bottom to top; and wherein the first through holes and the fourth through holes are respectively connected to the outside.
[0009] Furthermore, the top shell is rotatably connected to a rotating cover, and the rotating cover has a fifth through hole around its periphery. When the rotating cover rotates relative to the top shell, the fifth through hole is either connected to or not connected to the fourth through hole.
[0010] Furthermore, multiple flexible sheets are connected to the inner ring side edge of the fifth through hole. When the fifth through hole is connected to the fourth through hole, when airflow flows from bottom to top through the fifth through hole, the edges of each flexible sheet do not contact each other, and the flexible sheets unfold upwards to allow the fifth through hole between the multiple flexible sheets to communicate with the outside. When the fifth through hole is not connected to the fourth through hole, when airflow does not flow from bottom to top through the fifth through hole, the edges of each flexible sheet contact each other to allow the fifth through hole between the multiple flexible sheets to close with the outside.
[0011] Furthermore, the edges between the flexible sheets have a curved shape.
[0012] Furthermore, the bottom housing is provided with a plurality of gaskets in the circumferential direction to allow a second gap to be provided between the bottom end of the first through hole and the plane.
[0013] Furthermore, the controller is mounted on a circuit board, which is located inside the LED light column.
[0014] Furthermore, the circuit board is equipped with a PWM drive module, which is electrically connected to the LED beads and the controller respectively.
[0015] Furthermore, the LED light column is covered with a light-transmitting part with an arc-shaped protrusion.
[0016] Furthermore, the bottom shell, the second shell, and the top shell are made of light-transmitting material.
[0017] The beneficial effects of this utility model include:
[0018] 1. This lamp uses a long LED light column, which is more convenient to assemble than the traditional cylindrical light panel; the long light column can better adapt to the internal structure of the lamp, reducing production costs and time costs caused by assembly complexity.
[0019] 2. This lamp uses multiple light sensors on the first and second lamp panels to detect the brightness of light from the first housing, second housing, and top housing in real time. Based on these detection results, the controller independently controls the on / off state of each LED. When the brightness detected by some light sensors is too high, the controller will automatically turn off or dim the LEDs in that area to maintain consistency with the areas with lower brightness, making the overall brightness of the lamp more uniform and solving the problem of uneven brightness commonly found in traditional lamps.
[0020] 3. The lamp's interior features multiple through-holes, including a first, second, third, and fourth through-hole, which connect sequentially from bottom to top, forming a good airflow channel. External airflow can enter through the first through-hole, passing through the first gap, the inside of the LED lamp post, the third through-hole, and the fourth through-hole, carrying away the heat generated by the LED beads and effectively improving the lamp's heat dissipation performance. In addition, a rotating cover is provided on the top shell, and the fifth through-hole around it can connect or close with the fourth through-hole as needed. When the fifth through-hole connects with the fourth through-hole, the flexible sheet automatically unfolds under the action of airflow, further increasing the heat dissipation effect. When heat dissipation is not required, the flexible sheet closes to prevent dust from entering the lamp's interior, thus also serving a dustproof function.
[0021] 4. The circuit board is equipped with a PWM drive module, which, together with the controller, can independently control the on / off state and brightness of each LED bead, enabling the lamp to achieve a variety of lighting effects, such as simulating the effect of a flame lamp, increasing the display methods and fun of the lamp.
[0022] Furthermore, additional aspects and advantages of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the present invention. Attached Figure Description

[0034] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.
[0035] Reference Figures 1 to 8 As shown, in some embodiments, the present invention discloses an LED lamp, which includes: the LED lamp mainly includes a bottom shell 1, a first shell 2, a second shell 3, a top shell 4, and an LED lamp post 10.
[0036] Reference Figure 2 As shown, the lamp housing structure is as follows: It includes a bottom housing 1, which serves as the basic structure of the lamp and supports the entire lamp. A first housing 2 is connected upwards to the edge of the bottom housing 1. The first housing 2 is connected to the bottom housing 1, forming the main body of the lamp. A second housing 3 is connected to the top edge of the first housing 2. The second housing 3 is connected to the top edge of the first housing 2, further forming the outer shell structure of the lamp. A top housing 4 is connected to the top of the second housing 3, forming the top structure of the lamp.
[0037] Reference Figure 1 , Figure 3 Combination Figure 5 The LED light column 10 includes a first light panel 11 enclosed on all four sides and a second light panel 12 connected to and enclosed at the top of the first light panel 11. The first light panel 11 and the second light panel 12 are equipped with a plurality of LED beads 13 and a plurality of light sensors 14 spaced apart.
[0038] Reference Figure 1 , Figure 3 The first lamp panel 11 and the second lamp panel 12 are equipped with a plurality of LED beads 13 and a plurality of light sensors 14 spaced apart. The light sensors 14 are used to detect light brightness information from the first housing 2, the second housing 3, and the top housing 4. The LED beads 13 and the light sensors 14 are electrically connected to a controller 15. The controller 15 is electrically connected to the LED beads 13 and the light sensors 14 and is used to control the on / off state of the LED beads 13 based on the detection results of the light sensors 14.
[0039] Reference Figure 1 Combination Figure 3 As shown, the distances on the first housing 2 and the second housing 3 corresponding to the light sensor 14 on each of the first light panels 11 are consistent, and the distances on the top housing 4 corresponding to the light sensor 14 on the first light panel 11 are consistent. When the LED beads 13 illuminate the second housing 3 and the top housing 4, the second housing 3 and the top housing 4 reflect part of the light onto the light sensor 14, so that the controller 15 can output an independent control signal to control the LED beads 13 to turn on and off.
[0040] This lamp uses a long LED lamp post 10, which is easier to assemble compared to lamp posts on the market that use flexible circuit boards. The long LED lamp post 10, together with multiple light sensors 14 at different locations, can collect light brightness information from the first housing 2, the second housing 3, and the top housing 4. When some light sensors 14 detect excessively high brightness, the controller 15 will control the LED beads 13 near that light sensor 14 to turn off, thereby maintaining a more consistent brightness with the LED beads 13 on the LED lamp post 10 where some light sensors 14 have lower brightness, resulting in a more uniform overall brightness of the lamp.
[0041] The working principle of this lamp is as follows:
[0042] 1. Light detection: The light sensor 14 detects the light brightness information from the first housing 2, the second housing 3 and the top housing 4 in real time;
[0043] 2. Signal processing: The controller 15 analyzes the brightness at each position based on the detection results of the light sensor 14;
[0044] 3. Brightness adjustment: If the brightness detected by a certain light sensor 14 is too high, the controller 15 will send a signal to turn off or reduce the brightness of the LED beads 13 near the light sensor 14; conversely, if the brightness detected by a certain light sensor 14 is too low, the controller 15 will send a signal to turn on or increase the brightness of the LED beads 13 near the light sensor 14.
[0045] 4. Uniform brightness: Through the above adjustments, the overall brightness of the lamp can be kept relatively uniform, avoiding the uneven brightness problem commonly found in traditional lamps.
[0046] Reference Figure 1 or Figure 3As shown, the lamp also includes a mounting base 5, the center of which is connected to the inner surface of the bottom housing 1 via a connecting portion. The bottom housing 1 has multiple first through holes 91 around the perimeter of the mounting base 5, and a first gap 51 is provided between the perimeter of the mounting base 5 and the bottom housing 1. Each first lamp plate 11 has a second through hole 92 extending upwards from the outside to the inside at its base, and multiple third through holes 93 are provided on the second lamp plate 12. A fourth through hole 94 is provided around the perimeter of the top housing 4. The first through holes 91 and the fourth through holes 94 communicate with the outside. The first through hole 91, the first gap 51, the second through hole 92, the third through hole 93 and the fourth through hole 94 are connected from bottom to top. The airflow outside the lamp also flows from bottom to top between the first through hole 91, the first gap 51, the second through hole 92, the hollow part in the middle of the LED lamp post 10, the third through hole 93 and the fourth through hole 94, and carries away the heat generated by the LED beads on the first lamp board 11 and the second lamp board 12 in turn, and finally flows away from the third through hole 93 and the fourth through hole 94.
[0047] Reference Figure 3 In the illustrated embodiment, the top shell 4 is rotatably connected to a rotating cover 6, and the rotating cover 6 has a fifth through hole 95 around its periphery. When the rotating cover 6 rotates relative to the top shell, the fifth through hole 95 may or may not connect with the fourth through hole 94. The user can manually rotate the rotating cover to connect the fifth through hole 95 with the fourth through hole 94 for heat dissipation. At the same time, the connection between these two holes also allows the LED light on the top shell to pass through directly, creating an atmosphere different from the light transmitted through the second shell.
[0048] Continue to refer to Figures 3 to 4 , combined Figures 6 to 8 As shown, multiple flexible sheets 61 are connected to the inner edge of the fifth through hole 95. The flexible sheets 61 can be made of very thin plastic film or thin textile fabric. (Refer to...) Figure 6 Combination Figure 8 The state of the flexible sheet 61 affected by airflow is as follows: When the fifth through hole 95 is connected to the fourth through hole 94, when the airflow flows from bottom to top through the fifth through hole 95, that is, when the LED light board generates heat and needs to dissipate heat, the edges between each flexible sheet 61 do not contact, such as... Figure 8As shown, the flexible sheet 61 unfolds upwards, allowing the user to observe its graceful unfolding and allowing the fifth through-hole 95 between the multiple flexible sheets 61 to communicate with the outside. When the fifth through-hole 95 is not connected to the fourth through-hole 94, and when airflow does not flow from bottom to top through the fifth through-hole 95, the edges of each flexible sheet 61 contact each other, allowing the fifth through-hole 95 between the multiple flexible sheets 61 to close with the outside. At this time, the flexible sheet can also prevent external dust from entering the lamp, giving the lamp a good dustproof effect.
[0049] Reference Figure 7 As shown, in some embodiments, the edges between the flexible sheets 61 are curved. The curves, compared to the straight edges of the flexible sheets, allow adjacent flexible sheets to contact each other. A certain air pressure is required to open up multiple flexible sheets for air to escape.
[0050] Reference Figure 1 As shown, the bottom housing 1 is provided with a plurality of gaskets 19 around its circumference to allow a second gap 96 between the bottom end of the first through hole 91 and the plane. The dotted line part is the plane part, which allows the lamp to be supported higher and allows more airflow to enter the first through hole through the second gap, thereby increasing the heat dissipation effect.
[0051] Continue to refer to Figure 1 As shown, the controller 15 is mounted on a circuit board 16, which is located inside the LED lamp post 10. A PWM drive module 17 is mounted on the circuit board 16, and the PWM drive module 17 is electrically connected to both the LED beads 13 and the controller 15. Since the LED beads on the lamp board can be independently controlled to turn on and off, the lamp can use the PWM drive module 17 to control each LED bead to achieve a flame lamp display effect, thus increasing the lamp's display options.
[0052] Reference Figure 5 As shown, the LED light column 10 is covered with a light-transmitting part 18 with an arc-shaped protrusion. The light-transmitting part, together with the LED beads, enables the light fixture to have a better scattering effect.
[0053] In some embodiments, the bottom housing 1, the second housing 3, and the top housing 4 are made of light-transmitting material, so that almost the entire lamp can emit light.
[0054] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
