Description

Technical Field

[0001] The present invention relates to the field of lamps, and particularly to an LED lamp. Background Art

[0002] In recent years, due to advantages such as high energy efficiency, rich colors, and long lifespan, LED lamps have been widely used in the lighting field, especially in the bedside lamp and mood lamp markets.

[0003] From the perspective of the structural design of lamps, traditional LED lamps usually adopt the assembly of a cylindrical lamp housing and a cylindrical lamp board. Although this design meets the basic functional requirements of lamps to a certain extent, it also has obvious defects. The cylindrical lamp board usually requires the use of flexible lamp posts to achieve assembly, and the manufacturing cost of flexible lamp posts is relatively high, which undoubtedly increases the overall cost of the product. In addition, the installation and maintenance of flexible lamp posts are also relatively complex, further restricting their wide application in the market.

[0004] Secondly, the light transmission effect of existing LED bedside lamps or mood lamps is not ideal enough. Most products adopt a simple lamp housing structure. After the light emitted from the lamp beads passes through the transmission of the lamp housing, the phenomenon of uneven light transmission often occurs. For example, the light is stronger near the lamp beads and weaker far from the lamp beads, resulting in uneven brightness and darkness.

[0005] In view of the deficiencies of the existing technology, it is necessary to propose a new technical solution. Summary of the Invention

[0009] Further, the top housing is rotatably connected with a rotating cover body, the periphery of the selection cover body is provided with a fifth through hole. Among them, when the rotating cover body rotates relative to the top housing, the fifth through hole is respectively communicated with or not communicated with the fourth through hole.

[0010] Further, a plurality of flexible sheets are connected to the inner circumferential side edge of the fifth through hole. Among them, when the fifth through hole is respectively communicated with the fourth through hole, when the air flow flows from bottom to top through the fifth through hole, the edges between each flexible sheet do not contact, and the flexible sheets expand upward to allow the fifth through hole between the plurality of flexible sheets to communicate with the outside; when the fifth through hole is respectively not communicated with the fourth through hole, when the air flow does not flow from bottom to top through the fifth through hole, the edges between each flexible sheet contact to allow the fifth through hole between the plurality of flexible sheets to be closed to the outside.

[0011] Further, the running shape of the edges between the flexible sheets is a curve.

[0012] Further, a plurality of gaskets are circumferentially arranged on the bottom housing to allow a second gap to be provided between the bottom end of the first through hole and the plane.

[0013] Further, the controller is arranged on a circuit board, and the circuit board is arranged inside the LED lamp post.

[0014] Further, a PWM driving module is arranged on the circuit board, and the PWM driving module is electrically connected to the LED lamp beads and the controller respectively.

[0015] Further, a light-transmitting portion with an arc-shaped protrusion is covered above the LED lamp post.

[0016] Further, the materials of the bottom housing, the second housing and the top housing are light-transmitting materials.

[0017] The beneficial effects of the present invention include:

[0018] 1. The lamp adopts a long LED lamp column, which is more convenient to assemble than the traditional cylindrical lamp panel; the long lamp column can better adapt to the internal structure of the lamp and reduce the production cost and time cost caused by the complexity of assembly.

[0019] 2.

[0021] 4. A PWM drive module is provided on the circuit board, which can independently control the on and off and brightness of each LED lamp bead with the controller, so that the lamp can achieve a variety of lighting effects, such as simulating the effect of flame lamp, increasing the display method and fun of the lamp.

[0034] It should be understood that although the terms first, second, third, etc. may be used in the present 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 each other. For example, without departing from the scope of the present disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0035] Refer to 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 housing 1, a first housing 2, a second housing 3, a top housing 4, and an LED lamp post 10.

[0036] Refer to Figure 2As shown in the figure, the structure of the lamp housing is as follows: It includes a bottom housing 1, which serves as the basic structure of the lamp and is used to support the entire lamp. The edge of the bottom housing 1 is connected upward to a first housing 2. The first housing 2 is connected upward to the edge of the bottom housing 1, and the first housing 2 is connected to the bottom housing 1 to form the main body part of the lamp. The top edge of the first housing 2 is connected to a second housing 3. The second housing 3: is connected to the top edge of the first housing 2 and further constitutes the outer shell structure of the lamp. The top of the second housing 3 is connected to a top housing 4, and the top housing 4 is installed on the top of the second housing 3 to form the top structure of the lamp.

[0037] Referring to Figure 1 , Figure 3 Combined with Figure 5 the LED lamp post 10, the LED lamp post 10 includes a first lamp board 11 surrounded on four sides and a second lamp board 12 connected and surrounded to the top end of the first lamp board 11. The LED lamp post 10 includes a first lamp board 11 surrounded on four sides and a second lamp board 12 connected and surrounded to the top end of the first lamp board 11. A plurality of LED lamp beads 13 and a plurality of light sensors 14 arranged at intervals are provided on the first lamp board 11 and the second lamp board 12.

[0038] Referring to Figure 1 , Figure 3 A plurality of LED lamp beads 13 and a plurality of light sensors 14 arranged at intervals are provided on the first lamp board 11 and the second lamp board 12. The light sensors 14 are used to detect the light brightness information from the first housing 2, the second housing 3, and the top housing 4. The LED lamp beads 13 and the light sensors 14 are electrically connected to a controller 15. The controller 15 is electrically connected to the LED lamp beads 13 and the light sensors 14 and is used to control the on and off of the LED lamp beads 13 according to the detection results of the light sensors 14.

[0039] Referring to Figure 1 Combined with Figure 3 As shown in the figure, the distances between the first housing 2 and the second housing 3 corresponding to the light sensors 14 on each first lamp board 11 are the same, and the distances between the top housing 4 corresponding to the light sensors 14 on the first lamp board 12 are the same. When the LED lamp beads 13 irradiate light onto 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 sensors 14 to allow the controller 15 to output an independent control signal for controlling the on and off of the LED lamp beads 13.

[0040] This lamp uses a long LED lamp post 10, which is more convenient to assemble compared to the lamp posts with flexible printed circuit boards in the existing market. The long LED lamp post 10 cooperates with light sensors 14 at multiple different positions to collect the light brightness information from the first housing 2, the second housing 3, and the top housing 4. When the brightness detected by some of the light sensors 14 is too high, the controller 15 will control the LED lamp beads 13 near that light sensor 14 to turn off, so as to maintain a relatively consistent brightness with the LED lamp beads 13 on the LED lamp post 10 where some of the light sensors 14 detect lower brightness, making the overall brightness of the lamp more uniform.

[0041] The working principle of this lamp is as follows:

[0042] 1. Light detection: The light sensors 14 continuously detect the light brightness information from the first housing 2, the second housing 3, and the top housing 4;

[0043] 2. Signal processing: The controller 15 analyzes the brightness conditions at each position according to the detection results of the light sensors 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 lamp beads 13 near that 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 lamp beads 13 near that light sensor 14.

[0045] 4. Uniform brightness: Through the above adjustments, the overall brightness of the lamp can be kept relatively uniform, avoiding the common problem of uneven brightness in traditional lamps.

[0046] Refer to Figure 1 or Figure 3As shown, the lamp further includes a mounting base 5. The center of the mounting base 5 is connected to the inner surface of the bottom housing 1 through a connecting portion. A plurality of first through holes 91 are provided around the bottom housing 1 corresponding to the mounting base 5. A first gap 51 is provided between the periphery of the mounting base 5 and the bottom housing 1. The root of each first lamp board 11 is provided with a second through hole 92 that slopes upward from outside to inside. A plurality of third through holes 93 are provided on the second lamp board 12. The periphery of the top housing 4 is provided with a fourth through hole 94. Among them, the first through hole 91 and the fourth through hole 94 are respectively communicated 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 sequentially communicated from bottom to top. The air flow outside the lamp also sequentially 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 column 10, the third through hole 93 and the fourth through hole 94, sequentially taking away the heat generated by the LED lamp beads on the first lamp board 11 and the second lamp board 12, and finally flowing away from the third through hole 93 and the fourth through hole 94.

[0047] Referring to Figure 3 the embodiment shown, a rotary cover body 6 is rotatably connected to the top housing 4. A fifth through hole 95 is provided on the periphery of the selection cover body. When the rotary cover body 6 rotates relative to the top shell, the fifth through hole 95 is respectively communicated with or not communicated with the fourth through hole 94. The user can manually rotate the rotary cover body to make the fifth through hole 95 communicate with the fourth through hole 94 respectively for heat dissipation. At the same time, when these two holes are communicated, the LED light on the top shell can also be directly transmitted, and the light atmosphere is different from the light transmitted through the second housing.

[0048] Continuing to refer to Figures 3 to 4 , in combination with Figures 6 to 8 shown, a plurality of flexible sheets 61 are connected to the inner circumferential side edge of the fifth through hole 95. The flexible sheets 61 can be composed of very thin plastic films or thin textile fabrics. Referring to Figure 6 in combination with Figure 8 the state of the flexible sheet 61 affected by the air flow is as follows: when the fifth through hole 95 is respectively communicated with the fourth through hole 94, when the air flow flows from bottom to top through the fifth through hole 95, that is, when the LED lamp board generates heat and needs to dissipate heat, the edges between each flexible sheet 61 do not contact, as Figure 8As shown, the flexible sheet 61 is unfolded upward, and the user can observe that the flexible sheet is unfolding and floating, so as to allow the fifth through holes 95 between the plurality of the flexible sheets 61 to communicate with the outside world. When the fifth through holes 95 are not connected with the fourth through holes 94, respectively, and when the airflow does not flow from the fifth through holes 95 from bottom to top, the edges between each of the flexible sheets 61 are in contact, so as to allow the fifth through holes 95 between the plurality of the flexible sheets 61 to be closed with the outside world. At this time, the flexible sheet can also prevent external dust from entering the interior of the lamp, so that the lamp has a good dustproof effect.

[0049] Reference Figure 7 As shown, in some embodiments, the edge of the flexible sheet 61 is in the shape of a curve. The curve relative to the straight edge of the flexible sheet can make adjacent flexible sheets contact, and a certain air pressure is required to open multiple flexible sheets for exhaust.

[0050] Reference Figure 1 As shown, the bottom shell body 1 is circumferentially provided with a plurality of gaskets 19 to allow a second gap 96 to be provided between the bottom end of the first through hole 91 and the plane. The dotted line portion is the plane portion, so that the lamp is supported higher and more air flows into 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 arranged on a circuit board 16, and the circuit board 16 is arranged in the LED lamp post 10. A PWM driving module 17 is arranged on the circuit board 16, and the PWM driving module 17 is electrically connected to the LED lamp beads 13 and the controller 15 respectively. Since the LED lamp beads on the lamp board can be independently controlled to light up and down, the lamp can control each LED lamp bead through the PWM driving module 17 to achieve the display effect of the flame lamp, thereby increasing the display mode of the lamp.

[0052] Reference Figure 5 As shown, the top of the LED lamp post 10 is covered with a light-transmitting portion 18 with an arc-shaped protrusion, and the light-transmitting portion cooperates with the lamp beads to achieve a better scattering effect of the lamp.

[0053] In some embodiments, the bottom shell 1 , the second shell 3 , and the top shell 4 are made of light-transmitting materials, so that almost the entire lamp can emit light.

[0054] The above is only a preferred embodiment of the present invention. The present invention is not limited to the above implementation. As long as the technical effect of the present invention is achieved by the same means, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the scope of protection of the present disclosure.
