Description
Technical Field
[0001] This utility model relates to the field of smart home technology, specifically a colored cube LED sensor light. Background Technology
[0002] Sensor lights are a type of modern smart home appliance, typically installed at the head of the bed, beside the bed, or on the wall. Compared to traditional lights, sensor lights do not require manual switching. They usually have built-in sensors that can detect human movement such as passing by or waving, thus automatically switching on and off. Moreover, the light from sensor lights is usually softer than that of traditional lighting fixtures.
[0003] Unlike traditional LED lights that use bulbs for illumination, existing LED sensor lights typically use a light board structure. This structure is flatter, simpler, and more aesthetically pleasing. However, LED lights inevitably suffer damage after a period of use. If one of the LED beads in a series connection fails, it can even cause the beads behind it to stop working, thus requiring the light board to be replaced. However, the limiting methods for the light board are usually adhesive, soldering, clips, bolts, etc. For ordinary people, it is difficult to buy a new light board for replacement, or even impossible to replace the light board. They may have to discard the entire LED sensor light, resulting in waste, or spend more money to have it replaced by professionals. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a colored cube LED sensor light to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a colored cube LED sensor light, comprising a lamp body, a bulb holder installed in the middle of the top of the lamp body, and an LED bulb connected to the top of the bulb holder; a dam fixed to the top of the lamp body, and a lamp cover connected to the outer surface of the dam, with a sealing strip connected inside the lamp cover; limit plates fixed to both sides inside the lamp cover, and limit frames connected to both sides inside the lamp body, with a pre-tensioning spring connected between the limit frames and the lamp body.
[0006] By adopting the above technical solution, when the light source is damaged, the user only needs to press down on the limiting bracket to separate it from the limiting plate, and then remove the lamp cover upwards. Using traditional LED bulbs as the light source, when the LED bulb is damaged, the operation and principle of replacing the bulb are more familiar to more people than replacing the entire light board. This allows users to easily replace the damaged light source independently, avoiding the need to discard the entire LED sensor light or spend more money to find a professional to replace it. It should be noted that when replacing the LED bulb, the user should pay attention to electrical safety. Disconnect the charging cable from the charging port, and then remove the bolts and cover of the battery compartment in sequence before disassembling the battery. Cylindrical batteries can be used; the disassembly and assembly principle is simple and easy for users to operate independently. After installing the LED bulb, the user reinstalls the battery, the bolt cover of the battery compartment, and the charging cable. Then, the user presses down on the limiting bracket and lowers the lampshade. Once the lampshade is in place, the user releases the hand pressing the limiting bracket. The pre-tension spring drives the limiting bracket to reset and press against the limiting plate, thus completing the limiting and preventing the lampshade from falling upwards. During this process, the pre-tension spring continuously applies force to the limiting bracket. The pre-tension spring is compressed sequentially during assembly, so it is in a compressed and stored state, providing good vibration resistance and reducing the possibility of the limiting bracket shifting and separating from the limiting plate due to vibration. Furthermore, the presence of the retaining wall prevents the lampshade from moving forward, backward, left, or right, and from tilting, improving the lampshade's stability. The retaining wall, combined with the sealing strip, provides dust and water protection, extending the lifespan of the LED sensor light.
[0007] Furthermore, the LED bulb is detachably connected to the bulb holder.
[0008] By adopting the above technical solution and using traditional LED bulbs as the light source, when the LED bulbs are damaged, the operation and principle of replacing the bulbs are more familiar to more people than replacing the light board. This makes it easier for users to replace the damaged light source independently, without having to discard the entire LED sensor light or spend more money to find professionals to replace it.
[0009] Furthermore, the lampshade is detachably connected to the lamp body and the embankment, and the limiting frame abuts against the limiting plate.
[0010] By adopting the above technical solution, the user places the lampshade downwards. After the lampshade is placed, the user releases the hand pressing the limit frame. The pre-tightening spring drives the limit frame to reset and press against the limit plate to complete the limit, thus preventing the lampshade from falling upwards. During this process, the presence of the embankment prevents the lampshade from moving forward, backward, left, or right and from tilting.
[0011] Furthermore, the longitudinal section of the limiting frame is C-shaped, and the limiting frame is slidably connected to the main body of the lamp.
[0012] By adopting the above technical solution, when the light source is damaged, the user only needs to press the limit bracket to separate the limit bracket from the limit plate, and then remove the lampshade upwards.
[0013] Furthermore, there are two of each of the limiting plates and limiting frames, and two sets of pre-tensioning springs are provided.
[0014] By adopting the above technical solution, increasing the number of limiting plates and limiting brackets, and increasing the connection points of the lampshade, the stability of limiting the lampshade is improved. Increasing the number of springs can increase the force on the limiting bracket, thereby reducing the phenomenon of arbitrary displacement of the limiting bracket when not operated manually.
[0015] Furthermore, the sealing strip is made of EPDM rubber or silicone rubber.
[0016] By adopting the above technical solutions, both EPDM rubber and silicone rubber are rubbers with good weather resistance, which can be used for a long time and ensure sealing to prevent dust and moisture from entering.
[0017] Furthermore, a human infrared sensor is installed on the outer surface of the lamp body, a power switch is installed on one side of the outer surface of the lamp body, a charging interface is installed on the back of the lamp body, a battery compartment is provided at the bottom of the lamp body, and a control circuit board and a lithium battery are installed inside the lamp body.
[0018] By adopting the above technical solution, users can connect the charging cable to the charging interface to charge the battery in the battery compartment. At the same time, the lithium battery protection system inside the lamp body prevents overcharging and overheating. During charging, the charging cable directly supplies power to the control circuit board, human infrared sensor, LED bulb, and other electrical components of the lamp body, while also charging the battery in the battery compartment. After the charging cable is removed, the battery in the battery compartment supplies power to the control circuit board, human infrared sensor, LED bulb, and other electrical components of the lamp body. When in use, the user presses the power switch to turn on the lamp. When the user passes by the human infrared sensor or waves their hand in front of the human infrared sensor, the human infrared sensor detects the human movement and sends an electrical signal to the control circuit, which then turns on the LED bulb. To turn off the lamp, the user simply waves their hand again. Some sensor lights also use a human infrared sensor to detect when the user leaves and automatically turn off the LED bulb.
[0019] Furthermore, the human infrared sensor is model HC-SR501, and the charging interface is a Type-C interface.
[0020] By adopting the above technical solution, the Type-C interface is one of the mainstream charging interfaces at present, which can be compatible with most mobile phone charging cables, so charging is convenient. When a user passes by the human infrared sensor or waves his hand in front of the human infrared sensor, the human infrared sensor detects the human movement and sends an electrical signal to the control circuit, which then turns on the LED bulb.
[0021] Furthermore, the lamp body has cover plates connected to both sides of the top, and the cover plates are detachably connected to the lamp body by bolts. The inner wall of the lamp shade has a groove, and the sealing strip is embedded in the groove.
[0022] By adopting the above technical solution, when the limit frame or pre-tensioning spring is damaged, the cover plate can be removed to stop the limit frame, so that the limit frame can be removed from the lamp body, and the existence of the groove facilitates the disassembly and assembly of the sealing strip.
[0023] Furthermore, the LED bulb is either the DX-7642 smart bulb from Dishi, a full-spectrum light source, or the OMI-TY300 smart RGB bulb from Aimicarden.
[0024] By adopting the above technical solutions, the DX-7642 smart bulb from Dishi provides a full-spectrum light source, which is more eye-friendly; the OMI-TY300 smart RGB bulb from Aimicarden can adjust the color and brightness of the light source through remote control, and can switch between cool light source, warm light source and colored light source.
[0025] In summary, the present invention has the following main advantages:
[0026] 1. This utility model uses a bulb holder and an LED bulb as the light source. When the LED bulb is damaged, the operation and principle of replacing the bulb are more familiar to more people than replacing the light board. This makes it easier for users to replace the damaged light source independently, without having to discard the entire LED sensor light or spend more money to find a professional to replace it. The principle is simple and convenient for replacing the damaged light source.
[0027] 2. This utility model features a lampshade, a dam, and a sealing strip. The lampshade is detachable, allowing for easy removal to expose the LED bulb for replacement. The dam prevents the lampshade from moving forward, backward, left, or right, thus improving its stability. The dam, together with the sealing strip, provides dust and water protection, extending the lifespan of the LED sensor light and facilitating the protection of the LED bulb.
[0028] 3. This utility model, through the setting of a limiting plate, a limiting frame, and a pre-tightening spring, uses the limiting frame to hold the limiting plate in place, preventing the lampshade from falling upwards, thereby further improving the stability of the lampshade placement. During this process, the pre-tightening spring continuously applies force to the limiting frame. The pre-tightening spring is compressed sequentially during assembly, thus being in a compressed and stored state, providing good vibration resistance and reducing the phenomenon of the limiting frame shifting and separating from the limiting plate due to vibration. When disassembly is required, simply press down on the limiting frame to separate it from the limiting plate, and then remove the lampshade upwards. During installation, similarly, press down on the limiting frame, then place the lampshade downwards. After the lampshade is placed, release the hand pressing on the limiting frame, and the pre-tightening spring will drive the limiting frame to reset and hold against the limiting plate, thus completing the limiting. This secondary limiting of the lampshade improves structural stability and facilitates quick assembly and disassembly. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] The embodiments of this utility model will be described below based on its overall structure.
[0037] Example 1:
[0038] A colored cube-shaped LED sensor light, such as Figures 1-5As shown, the lamp includes a main body 1, a bulb holder 7 installed at the top center of the main body 1, an LED bulb 8 connected to the top of the bulb holder 7, and the LED bulb 8 detachably connected to the bulb holder 7; a dam 9 is fixed to the top of the main body 1, and a lampshade 2 is connected to the outer surface of the dam 9, the lampshade 2 detachably connected to the main body 1 and the dam 9; a sealing strip 10 is connected inside the lampshade 2, the sealing strip 10 being made of EPDM rubber or silicone rubber; limit plates 11 are fixed to both sides inside the lampshade 2, and limit frames 12 are connected to both sides inside the main body 1, the limit frames 12 abutting against the limit plates 11, and the longitudinal section of the limit frames 12 is "C". The lamp holder 12 is slidably connected to the lamp body 1 in a "U" shape. A pre-tensioning spring 13 connects the lamp holder 12 and the lamp body 1. There are two limit plates 11 and two limit holders 12. There are two sets of pre-tensioning springs 13. When the light source is damaged, the user only needs to press the limit holder 12 to separate the limit holder 12 from the limit plate 11, and then remove the lamp cover 2 upwards. The lamp uses a traditional LED bulb 8 as the light source. When the LED bulb is damaged, the operation and principle of replacing the bulb are more familiar to more people than replacing the lamp board. This makes it easier for the user to replace the damaged light source independently, without having to discard the entire lamp. Replacing an LED sensor light may require more money and professional replacement. It is important to note that when replacing LED bulb 8, users should pay attention to electrical safety. Disconnect the charging cable from the charging port 6, and then remove the bolts and cover 14 of the battery compartment 5. The battery can be a cylindrical battery, and its disassembly and assembly are simple and easy for users to perform independently. After replacing LED bulb 8, reinstall the battery, the bolts and cover 14 of the battery compartment 5, and the charging cable. Then, press down on the limit bracket 12, and lower the lampshade 2 downwards. After the lampshade 2 is in place, release the pressure on the limit bracket. The hand of the frame 12 is driven by the pre-tightening spring 13 to reset the limit frame 12 and press against the limit plate 11 to complete the limit and prevent the lamp cover 2 from falling upward. During this period, the pre-tightening spring 13 continuously applies force to the limit frame 12. The pre-tightening spring 13 is compressed sequentially during assembly, so it is in a compressed and stored state, which has good vibration resistance and reduces the phenomenon of the limit frame 12 displacing and separating from the limit plate 11 due to vibration. In addition, the presence of the cofferdam 9 prevents the lamp cover 2 from moving forward, backward, left, or right and tilting, which improves the stability of the lamp cover 2. Furthermore, the cofferdam 9, together with the sealing strip 10, can play a role in dustproofing and waterproofing, and extend the service life of the LED sensor light.
[0039] See Figure 1 , Figure 2 and Figure 4In the above embodiment, a human infrared sensor 3, model HC-SR501, is installed on the outer surface of the lamp body 1. A power switch 4 is installed on one side of the outer surface of the lamp body 1, and a charging interface 6, which is a Type-C interface, is installed on the back of the lamp body 1. A battery compartment 5 is provided at the bottom of the lamp body 1, and a control circuit board and a lithium battery are installed inside the lamp body 1. Users can connect to the charging interface 6 via a charging cable to charge the battery in the battery compartment 5. At the same time, the lithium battery protection system inside the lamp body 1 prevents overcharging and overheating. During charging, the charging cable directly powers the control circuit board and human infrared sensor of the lamp body 1. 3. The LED bulb 8 and other electrical components are powered, and the battery in the battery compartment 5 is charged at the same time. After the charging cable is removed, the battery in the battery compartment 5 powers the control circuit board of the lamp body 1, the human infrared sensor 3, the LED bulb 8 and other electrical components. When in use, the user presses the power switch 4 to turn on the lamp. When the user passes by the human infrared sensor 3 or waves his hand in front of the human infrared sensor 3, the human infrared sensor 3 detects the human movement and sends an electrical signal to the control circuit, which then turns on the LED bulb 8. To turn it off, the user only needs to wave his hand again. Some sensor lights also use the human infrared sensor 3 to detect when the user leaves and the LED bulb 8 turns off automatically.
[0040] Example 2:
[0041] Based on the above embodiment one, the following settings are now adopted to address different common issues.
[0042] See Figure 4 In the above embodiments, the LED bulb 8 is either the DX-7642 smart bulb from Dishi, a full-spectrum light source, or the OMI-TY300 smart RGB bulb from Aimicarden. The DX-7642 smart bulb from Dishi has a full-spectrum light source, which is more eye-friendly. The OMI-TY300 smart RGB bulb from Aimicarden can adjust the color and brightness of the light source through remote control, and can switch between cool light source, warm light source, and colored light source.
[0043] Example 3:
[0044] Based on the above embodiment one, the following settings are now adopted to increase practicality.
[0045] See Figures 1-5 In the above embodiment, cover plates 14 are connected to both sides of the top of the lamp body 1. The cover plates 14 are detachably connected to the lamp body 1 by bolts. When the limiting frame 12 or the pre-tightening spring 13 is damaged, the cover plates can be removed to stop the limiting frame 12, so that the limiting frame 12 can be removed from the lamp body 1. The inner wall of the lamp cover 2 is provided with a groove, and the sealing strip 10 is embedded in the groove to increase the stability of the sealing strip 10.
[0046] The implementation principle of this utility model is as follows: First, the user can connect the charging cable to the charging interface 6 to charge the battery in the battery compartment 5. At the same time, the lithium battery protection system in the lamp body 1 prevents overcharging and overheating. During charging, the charging cable directly supplies power to the control circuit board, human infrared sensor 3, LED bulb 8 and other electrical components of the lamp body 1, and charges the battery in the battery compartment 5. After the charging cable is removed, the battery in the battery compartment 5 supplies power to the control circuit board, human infrared sensor 3, LED bulb 8 and other electrical components of the lamp body 1. When in use, the user presses the power switch 4 to turn on the lamp. When the user passes by the human infrared sensor 3 or waves his hand in front of the human infrared sensor 3, the human infrared sensor 3 detects the human movement and sends an electrical signal to the control circuit, which then turns on the LED bulb 8. To turn it off, the user only needs to wave his hand again. Some sensor lights also use the human infrared sensor 3 to detect when the user leaves and the LED bulb 8 automatically turns off.
[0047] When the light source is damaged, the user only needs to press down on the limiting bracket 12 to separate it from the limiting plate 11, and then remove the lamp cover 2 upwards. Using a traditional LED bulb 8 as the light source, replacing the bulb is easier and more familiar to most people than replacing the entire light board, allowing users to easily replace the damaged light source independently without discarding the entire LED sensor light or spending more money to hire a professional. It is important to note that when replacing the LED bulb 8, the user should pay attention to electrical safety. Disconnect the charging cable from the charging port 6, and then remove the bolts and cover 14 of the battery compartment 5 in sequence before disassembling the battery. Cylindrical batteries can be used; the disassembly and assembly principle is simple and easy for the user to operate independently. After replacing the LED bulb 8, the user should remove the battery... After reinstalling the bolt cover 14 and charging cable of the battery compartment 5, the user presses down on the limiting frame 12 and then places the lamp cover 2 downwards. After the lamp cover 2 is placed, the user releases the hand pressing the limiting frame 12. The pre-tension spring 13 drives the limiting frame 12 to reset and press against the limiting plate 11 to complete the limiting, thus preventing the lamp cover 2 from falling upwards. During this process, the pre-tension spring 13 continuously applies force to the limiting frame 12. The pre-tension spring 13 is compressed sequentially during assembly, so it is in a compressed and stored state, which has good vibration resistance and reduces the phenomenon of the limiting frame 12 displacing and separating from the limiting plate 11 due to vibration. In addition, the presence of the cofferdam 9 prevents the lamp cover 2 from moving forward, backward, left, or right and tilting, which improves the stability of the lamp cover 2. Furthermore, the cofferdam 9, together with the sealing strip 10, can play a role in dustproofing and waterproofing, extending the service life of the LED sensor light.
