A type of magnetic induction light for cabinets

Abstract

This utility model discloses a cabinet magnetic induction lamp, belonging to the field of magnetic induction lamps. The utility model includes a lamp housing and three metal patches. A silicone sleeve is wrapped around the lower outer wall of the three metal patches, and silicone pads are installed around the top of the lamp housing. This utility model uses a U-shaped design, where the silicone sleeve, made of soft silicone, wraps around the lower outer wall of the metal patches, completely covering the front side (the side in contact with the lamp body's magnet). This forms a contact link between the magnet, silicone, and the metal patch. When the cabinet is quickly closed, the lamp body causes the magnet to impact the metal patch. At this time, the silicone sleeve undergoes elastic compression (up to 30%-50% of its own thickness), converting the instantaneous concentrated impact force into the elastic potential energy of the silicone deformation, which is then slowly released. This reduces the impact force, avoids a hard collision between the magnet and the metal patch, and prevents dents or paint peeling on the patch surface due to impact.

Description

Technical Field

[0001] This utility model relates to the field of magnetic induction lamps, specifically a magnetic induction lamp for cabinets. Background Technology

[0002] Cabinet magnetic sensor lights are a modern lighting device that integrates magnetic fixing and automatic sensing functions. They are mainly used inside furniture such as cabinets, wardrobes, bookcases, and storage cabinets to provide convenient and efficient auxiliary lighting for specific areas. They represent the trend of home lighting towards intelligence, humanization, and wireless technology.

[0003] Existing magnetic sensor lights for cabinets first attach a metal patch to the cabinet body using double-sided tape, and then use a magnet inside the lamp housing to attract the lamp body to the metal patch. However, when the cabinet is opened or closed (such as when the cabinet door is slammed shut), the lamp body will experience an impact perpendicular to the patch due to inertia (such as the lamp body hitting the patch upwards or sliding and rubbing against the patch laterally). This causes a rigid collision between the magnet and the patch's metal, resulting in paint peeling, deformation, or wear on the electroplating layer of the magnet (affecting rust resistance). Furthermore, because the top of the lamp housing is in direct contact with the cabinet surface (solid wood, painted, glass, etc.), when the cabinet vibrates (such as when a kitchen range hood is running or when the cabinet door is opened or closed), the edge of the lamp housing is prone to lateral friction or impact with the cabinet, resulting in scratches on the lamp housing surface, paint peeling off the cabinet, or damage to the wood grain, thereby reducing the lifespan of the lamp housing. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a cabinet magnetic induction light to solve the technical problem that when the cabinet is switched on or off, the light body will generate an impact perpendicular to the patch due to inertia, causing the magnet to collide with the patch's metal rigidity, which in turn causes the patch surface to peel off or deform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cabinet magnetic induction lamp, comprising a lamp housing and three metal patches, the outer walls of the three metal patches being wrapped with silicone sleeves, silicone pads being installed around the top of the lamp housing, and removable nano-adhesive being provided on the top of the silicone pads, three magnets being disposed inside the upper part of the lamp housing, and a circuit board being installed inside the lamp housing, with LED lights mounted on the circuit board.

[0006] By adopting the above technical solution, since the cabinet is mostly made of non-magnetic materials (wood or plastic), the metal patch is attached to the cabinet with double-sided adhesive and then attracted to the magnet inside the lamp housing to fix the lamp body.

[0007] Furthermore, the circuit board is also equipped with a main control chip, an infrared sensor, and a light sensor, the infrared sensor being a PIR sensor.

[0008] By adopting the above technical solution, the infrared sensor and the light sensor can be controlled by the main control chip.

[0009] Furthermore, the three magnets correspond one-to-one with the three metal patches.

[0010] By adopting the above technical solution, the three-point correspondence makes the magnetic contact area more uniform. Combined with the high attraction of neodymium iron boron magnets, it ensures that the lamp body can still be firmly fixed in the case of cabinet switching vibration.

[0011] Furthermore, the bottom of the lamp housing is equipped with a first sensing window, a transparent cover, and a second sensing window, respectively, from left to right.

[0012] By adopting the above technical solution, the external corresponding positions of the infrared sensor, the light sensor and the LED light are clearly defined, avoiding the problem of the sensing window blocking the lighting or the lighting light interfering with the sensor due to the chaotic layout of the window or the cover.

[0013] Furthermore, the first sensing window corresponds to the infrared sensor, and the first sensing window is made of a ceramic filter or a zinc sulfide sheet.

[0014] By adopting the above technical solutions, the transmittance of ceramic filters or zinc sulfide sheets to mid-infrared light is ≥90%, ensuring that human infrared signals can be efficiently transmitted to PIR sensors, avoiding sensing delays or failures caused by low infrared transmittance in ordinary transparent materials (such as PC).

[0015] Furthermore, the second sensing window corresponds to the light sensor, and the second sensing window is made of transparent PC or ultra-white glass.

[0016] By adopting the above technical solution, the high transmittance of visible light (400-760nm) of transparent PC or ultra-white glass materials is utilized to enable the light sensor 2 to detect ambient light.

[0017] Furthermore, the LED light corresponds to a transparent cover, which is made of PMMA material.

[0018] By adopting the above technical solution, the visible light transmittance is ≥92% (close to ultra-white glass), and a soft light effect can be achieved through micro-frosting treatment, avoiding the glare of direct LED light and improving the user experience.

[0019] Furthermore, the magnet is a neodymium iron boron strong magnet, and the magnet surface is electroplated (such as nickel plating or zinc plating).

[0020] By adopting the above technical solution, the magnet is isolated from moisture and oil through the electroplating layer, which prevents the magnet from rusting (such as in bathroom cabinets and kitchen cabinets) and extends the life of the magnetic components.

[0021] Furthermore, the metal patch is made of low-carbon steel.

[0022] By adopting the above technical solution, the cabinet is mostly made of non-magnetic materials (wood or plastic), and the metal patch is limited to low carbon steel (high magnetic permeability and low cost), so that it can efficiently transmit the magnetic attraction force and become the magnetic carrier between the lamp body and the cabinet.

[0023] Furthermore, the lamp housing is made of ABS plastic.

[0024] By adopting the above technical solution, the lamp housing is made of ABS plastic, which has an impact resistance 3-5 times that of ordinary plastics and can withstand the impact of cabinet switch collisions and accidental lamp drops.

[0025] In summary, the present invention has the following main advantages: 1. This utility model involves wrapping a silicone sleeve around the lower outer wall of a metal patch. The material is soft silicone (combined with industry-standard design, Shore hardness 20-30HA, possessing high elasticity and low permanent deformation characteristics). Its structure is a U-shaped wrap, exposing only the back of the metal patch (the fixing surface with double-sided adhesive) and completely covering the front of the patch (the side in contact with the lamp body magnet), forming a contact link between the magnet, silicone, and the metal patch. When the cabinet closes quickly, the lamp body drives the magnet to impact the metal patch. At this time, the silicone sleeve will first undergo elastic compression (the compression can reach 30%-50% of its own thickness), converting the instantaneous concentrated impact force into the elastic potential energy of silicone deformation, and then slowly releasing it. To reduce impact and prevent hard collisions between the magnet and the metal patch, the silicone sleeve prevents dents and paint peeling on the patch surface (low-carbon steel patches without anti-corrosion coatings are prone to rust; the silicone sleeve reduces coating wear). It also protects the magnet's electroplated layer (nickel or zinc plating) from scratching and peeling off. Furthermore, when the cabinet vibrates (e.g., the range hood causes cabinet vibration), the light fixture may experience slight lateral sliding on the metal patch. In this case, the anti-slip surface of the silicone sleeve (with a coefficient of friction of approximately 0.8, much higher than the 0.3 between metals) increases the friction between the light fixture and the patch, limiting the sliding range. Even if sliding occurs, it is soft friction between the silicone and the magnet, rather than hard friction between metals, thus preventing scratches and wear on the patch surface. 2. This utility model, by incorporating silicone pads and removable nano-adhesive, prevents the lamp body from swaying with the cabinet body when the cabinet door is opened (e.g., due to inertia). The edge of the lamp housing is prone to impacting the cabinet sidewall. At this time, the silicone pads around the top of the lamp housing undergo lateral compression, absorbing the vibration energy and preventing the lamp housing edge (ABS plastic, with low hardness) from directly impacting the cabinet body (e.g., the hard edge of a painted cabinet). This significantly reduces corner cracks and surface scratches caused by impacts, and also prevents the cabinet body from being scratched by the lamp housing (e.g., the wood grain of a solid wood cabinet being rubbed by the lamp housing edge). Furthermore, the soft nature of the silicone pads transforms the hard friction between plastic and wood or paint into soft friction between silicone and the cabinet body. The slight elasticity of the silicone surface can also adapt to minor unevenness on the cabinet surface (e.g., the raised wood grain of a solid wood cabinet), preventing damage to both sides due to friction. Therefore, through the dual buffer design of the silicone sleeve and silicone pads, the metal patch (low carbon steel) is protected from magnetic impact and wear, extending the life of the magnetic components, while also protecting the lamp housing (ABS). The plastic material prevents scratches on the cabinet surface, maintains the integrity of the appearance, and also reduces collision noise. Attached Figure Description

[0028] 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.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A type of magnetic induction light for cabinets, such as Figures 1-5As shown, the lamp includes a lamp housing 1 and three metal patches 9, each 1 mm thick. A silicone sleeve 10, 0.2-0.5 mm thick, covers the lower outer wall of each metal patch 9. Silicone pads 11, 0.8-1 mm thick, are installed around the top of the lamp housing 1, with a removable nano-adhesive 12 on top. The removable nano-adhesive 12 is 0.3-0.5 mm thick. Three magnets 8 are located inside the lamp housing 1. A circuit board 3 is also installed inside the lamp housing 1, with LED lights 4 mounted on the circuit board 3. Since the cabinet is mostly made of non-magnetic materials (wood or plastic), the metal patches 9 are attached to the cabinet with double-sided adhesive and then attracted to the magnets 8 inside the lamp housing 1, thus fixing the lamp. The three magnets 8 correspond one-to-one with the three metal patches 9, ensuring a more uniform magnetic contact area. Combined with the high attraction of neodymium iron boron magnets, this ensures the lamp remains firmly fixed even when the cabinet vibrates during switching.

[0031] See Figures 1-3 The circuit board 3 is also equipped with a main control chip 5, an infrared sensor 6, and a light sensor 2. Both the infrared sensor 6 and the light sensor 2 are electrically connected to the main control chip 5. The infrared sensor 6 is a PIR sensor, so that the main control chip 5 can control the infrared sensor 6 and the light sensor 2. From left to right, the bottom of the lamp housing 1 is equipped with a first sensing window 13, a transparent cover 7, and a second sensing window 14, which clearly defines the external corresponding positions of the infrared sensor 6, the light sensor 2, and the LED light 4, avoiding the problem of the sensing window blocking the lighting or the lighting light interfering with the sensor due to the chaotic layout of the window or cover. The LED light 4 corresponds to the transparent cover 7. The transparent cover 7 is made of PMMA material with a visible light transmittance of ≥92% (close to ultra-white glass), and can achieve a soft light effect through micro-frosting treatment to avoid the direct glare of the LED and improve the user experience.

[0032] See Figures 1-3 The magnet 8 is a neodymium iron boron strong magnet, and the surface of the magnet 8 is electroplated (such as nickel plating or zinc plating). The electroplating layer isolates the magnet 8 from moisture and oil stains, preventing the magnet 8 from rusting (such as in bathroom cabinets and kitchen cabinets), and extending the life of the magnetic components. The metal patch 9 is made of low carbon steel. The cabinet body is mostly made of non-magnetic materials (wood or plastic), so the metal patch is limited to low carbon steel (high magnetic permeability and low cost) so that it can efficiently transmit the magnetic attraction force and become the magnetic carrier between the lamp body and the cabinet body. The lamp shell 1 is made of ABS plastic. The impact resistance of the lamp shell is 3-5 times that of ordinary plastic, and it can withstand the impact of cabinet switching collisions and accidental dropping of the lamp body.

[0033] Example 2: Based on the above embodiment 1, in order to enable the infrared sensor 6 to sense the human body, the first sensing window 13 will be made of the following material.

[0034] Specifically, the first sensing window 13 corresponds to the infrared sensor 6. The first sensing window 13 is made of a ceramic filter or a zinc sulfide sheet. The transmittance of the ceramic filter or zinc sulfide sheet to mid-infrared is ≥90%, which ensures that the human infrared signal can be efficiently transmitted to the PIR sensor and avoids the sensing delay or failure caused by the low infrared transmittance of ordinary transparent materials (such as PC).

[0035] Example 3: Based on the above embodiment 1, in order to enable the light sensor 2 to detect ambient light, the second sensing window 14 will be made of the following materials.

[0036] Specifically, the second sensing window 14 corresponds to the light sensor 2. The second sensing window 14 is made of transparent PC or ultra-white glass. It utilizes the high transmittance of visible light (400-760nm) of transparent PC or ultra-white glass material so that the light sensor 2 can detect ambient light.

[0037] The working principle of this utility model is as follows: First, before use, the user needs to install the sensor light. The user can peel off the double-sided adhesive on the back of the metal patch 9 and stick the metal patch with the silicone sleeve 10 to the designated position on the cabinet (such as the inside of the wardrobe or the bottom of the cabinet). Press for 30 seconds to ensure adhesion (the low carbon steel patch is magnetic, preparing for magnetic attraction); peel off the release paper of the removable nano adhesive 12 on the silicone pad 11 at the top of the lamp housing 1, align the lamp housing 1 with the metal patch 9, so that the three neodymium iron boron magnets 8 inside the lamp housing 1 are attracted to the three metal patches point-to-point, and at the same time, the removable nano adhesive 12 fills the gap between the lamp housing and the cabinet to complete the fixation; Light sensor 2 detects ambient light intensity through the second sensing window 14 (transparent PC / ultra-white glass): if the light intensity is ≥200 lux (daytime or indoor lights on), light sensor 2 sends a "high-level signal" to the main control chip 5, the main control chip 5 blocks the signal of infrared sensor 6, and the lamp remains off (energy saving); if the light intensity is <200 lux (night / dim environment): light sensor 2 sends a low-level signal, the main control chip 5 allows infrared sensor 6 to enter the trigger waiting state; When a user reaches into the cabinet (e.g., to retrieve clothes from a wardrobe or tableware from a cupboard), the mid-infrared light (8-14μm) radiated by the human body penetrates through the first sensing window 13 and is detected by the infrared sensor 6 (PIR). The infrared sensor 6 sends a trigger signal (high level) to the main control chip 5. After the chip confirms the signal is valid, it sends a light-on command to the LED driver circuit. The driver circuit is turned on, providing constant current power (e.g., 200mA) to the LED light 4. The LED light emits light outward through the transparent cover 7, illuminating the inside of the cabinet. Throughout the process, the silicone sleeve 10 absorbs the vibration of the lamp body and the metal patch 9, and the silicone pad 11 prevents the lamp housing 1 from colliding with the cabinet.
