Description

Technical Field

[0001] The present invention relates to the technical field of lighting appliances, and in particular to a spaced ceiling lamp with an independently developed light angle. Background Art

[0002] Home lighting is a combination of function and aesthetics. Through reasonable classification, control of technical indicators, and scene-based design, it can not only meet basic needs but also enhance the living experience, making light the "invisible designer" of the space.

[0003] There are many defects in the existing home lighting fixtures sold on the market during use. For example: 1. The switch control operation is inconvenient, and the operator needs to search and grope for the night light switch in the absence of lighting; 2. The lamps cannot be remotely turned on; 3. The light source surfaces of the existing ceiling lamps on the market are all downward, and the light output angles are unreasonable, which is likely to cause harm to the human eye; 4. The brightness is insufficient to meet the living needs. Therefore, we designed a spaced ceiling lamp with an independently developed light angle to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a spaced ceiling lamp with an independently developed light angle. Through multi-dimensional innovations in structure, optics, and intelligent control, it solves the core pain points of traditional lamps in aspects such as glare control, light efficiency balance, and intelligent experience, and combines safety, comfort, and energy conservation, providing a better solution for high-demand lighting scenarios.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A spaced ceiling lamp with an independently developed light angle, including a ceiling lamp body. The ceiling lamp body is composed of a top fixing system, a suspension and support system, and a light output component. The light output component emits light through diffuse reflection, and the light output component is hidden and designed to prevent glare. A control module is integrated in the ceiling lamp body, and the control module is equipped with a mobile phone APP, which can remotely adjust the brightness, can linearly dim from 0 to 100%, and the color temperature is 2700K - 5600K. Preset "reading", "watching movies", and "night light" scene modes, and support timed switching and adaptive light sensing adjustment.

[0007] Preferably, the top fixing system includes a hanging plate, a ceiling mounting plate, and a power module. The hanging plate is made of high-strength metal material and is firmly connected to the ceiling through expansion screws. The ceiling mounting plate is fixed to the hanging plate through countersunk head screws to ensure load-bearing safety. The power module is integrated inside the ceiling mounting plate, adopts a waterproof and insulating design, and is connected to the light source through a hidden line.

[0008] Preferably, the suspension and support system includes steel wire ropes and aluminum rings. The ceiling suction disc is connected to the aluminum ring by three stainless steel wire ropes. The length of the wire ropes is adjustable. The aluminum ring is an annular metal frame with an anodized surface.

[0009] Preferably, the light-emitting component includes a diffusion plate and a light source module. The diffusion plate is a multi-layer optical diffusion plate made of PC + nano diffuse reflection particles, with a thickness of 3 - 5 mm and a micro prism array designed on the surface. The diffusion plate is fixed to the bottom of the aluminum ring 5 by screws to achieve secondary refraction and diffuse reflection of light. The light source module selects high color rendering index (Ra≥98) LED lamp beads and is connected in parallel through quick plug-in terminals. The light source module is fixed to the inner side of the aluminum ring by spring screws, and the distance between the light-emitting surface and the diffusion plate is 2 - 3 cm.

[0010] Preferably, the inner wall of the aluminum ring is sprayed with a high reflectivity coating with a reflectivity of ≥95%. The light source module emits light upward, and after being reflected by the inner wall of the aluminum ring, it is diffusely reflected downward through the diffusion plate.

[0011] Preferably, the light source module is hidden inside the aluminum ring. The spacing between the light sources of the light source module is 15 - 20 mm. The angle between the light-emitting surface of the light source module and the diffusion plate forms a light-shielding angle of ≥30°. Combined with the diffuse reflection of the diffusion plate, the surface brightness of the lamp is ≤1000 cd / ㎡.

[0012] Preferably, the control module is an integrated Wi-Fi / Bluetooth dual-mode chip, supporting access to mainstream intelligent platforms. The control module is built-in with an ambient light sensor and an infrared receiving module.

[0013] Preferably, the control module can achieve remote control, monitor the status of the lamp in real time through the APP, support group management of multiple devices, and be compatible with voice assistants.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the high-strength metal hanging plate is connected to the ceiling by expansion screws, and the ceiling suction disc and the hanging plate are fixed doubly, significantly enhancing the load-bearing capacity and ensuring the safety of long-term use. The stainless steel wire ropes with a three-pronged structure support a height adjustment of 5 - 15 cm, facilitating precise calibration of the level during installation and adapting to different floor height environments. The anodizing treatment of the aluminum ring improves the heat dissipation efficiency, avoids the attenuation of the light source module due to high temperature, and extends the service life. The light source module adopts a modular design (quick plug-in terminals + spring screw fixation), making replacement and maintenance convenient and reducing after-sales costs.

[0016] 2. In the present invention, the light source is hidden inside the aluminum ring to form a light-shielding angle of ≥30°. Combined with the secondary refraction of the micro-prism array of the diffusion plate, the surface brightness of the lamp is ≤1000 cd / ㎡ and the UGR is ≤19, meeting the glare-free standard and being superior to the traditional single light-shielding solution. By optimizing the angle of the diffusion plate prism (45° - 60°) and the distance from the light source through optical simulation, the main light-emitting angle is controlled within 120° - 150°, and the brightness uniformity is ≥0.85, eliminating the light spot, making it suitable for scenarios such as offices and classrooms that require high-uniform illumination. The highly reflective coating on the inner wall of the aluminum ring (reflectivity ≥95%) improves the light efficiency utilization rate. Combined with the diffuse reflection path of the upward-emitting light source, while achieving a high illuminance (≥800 lx), the surface brightness of the lamp is controlled at ≤500 cd / ㎡, avoiding the problem of "strong light dazzling" and meeting the contradictory requirements of high-demand scenarios.

[0017] 3. In the present invention, it can achieve scene-based adaptability, combine environmental perception and user habit learning, automatically adapt to scene requirements, with an energy-saving rate more than 30% higher than that of traditional lamps, support Wi-Fi / bluetooth dual-mode connection, be compatible with mainstream platforms such as Mijia and Tuya and voice assistants. Users can remotely monitor and group-manage multiple devices through the APP, and still can locally control through Bluetooth when the network is disconnected, ensuring operation stability, and the interaction has convenience and compatibility.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Refer to Figures 1 - 3 , a space-saving ceiling lamp with an independently developed light-emitting angle, comprising a ceiling lamp body, and the ceiling lamp body is composed of a top fixing system, a suspension and support system, and a light-emitting component.

[0024] The top fixing system includes a hanging plate 1, a ceiling suction cup 2 and a power module 3. The hanging plate 1 is made of high-strength metal material and is firmly connected to the ceiling through expansion screws. The ceiling suction cup 2 is fixed to the hanging plate 1 through countersunk screws to ensure load-bearing safety. The power module 3 is integrated inside the ceiling suction cup 2, adopts a waterproof and insulating design, and is connected to the light source through a hidden circuit.

[0025] The suspension and support system includes a steel wire rope 4 and an aluminum ring 5. The ceiling suction cup 2 is connected to the aluminum ring 5 through three stainless steel wire ropes 4. The three stainless steel wire ropes 4 are in a trident structure, with a load-bearing capacity of 15 kg. The length of the wire rope 4 can be adjusted to precisely control the horizontal height of the lamp, and the adjustment range is 5 - 15 cm. The aluminum ring 5 is an annular metal frame, the surface is anodized, and the aluminum ring integrates 6063-T5 heat dissipation fins (the surface area is 40% larger than the conventional design), and cooperates with a graphene thermal conductive gasket (thermal resistance < 0.5℃·in2 / W), enabling the aluminum ring 5 to carry the diffusion plate 6 and the light source module 7 while providing a heat dissipation function.

[0026] The length of the steel wire rope 4 is adjusted through an adjustable locking device. Specifically, the lower end of the steel wire rope 4 is divided into 3 independent branches, and the end of each branch is fixed to three symmetric mounting points of the diffusion plate 6 through metal buckles or screw fasteners to form a stable triangular support structure to ensure uniform force. The three strands of the steel wire rope 4 converge upward into a single main rope, pass through the adjustment device (such as a graduated metal sleeve or a gear assembly), and are finally fixed to the load-bearing hanging plate of the ceiling suction cup 2 through a locking bolt. This is the prior art and will not be elaborated here.

[0027] The light-emitting component emits light through diffuse reflection, and the light-emitting component is hidden and anti-glare designed. The light-emitting component includes a diffusion plate 6 and a light source module 7. The diffusion plate 6 adopts a magnetic attraction + limit pin design, and the disassembly and assembly time < 30 seconds. The diffusion plate is a self-developed multi-layer optical diffusion plate, made of PC + nano diffuse reflection particles, with a thickness of 3 - 5 mm, and a micro prism array is designed on the surface. It is fixed to the bottom of the aluminum ring 5 through screws to achieve secondary refraction and diffuse reflection of light. Specifically, the substrate of the diffusion plate 6 is 5 mm optical-grade PC, with a light transmittance of 91% and a haze of 85%. The surface structure of the diffusion plate 6 is a hexagonal micropore array, with a pore diameter of 0.5 mm, a spacing of 0.3 mm, an etching depth of 50 μm in the central area, and 200 μm in the edge area to eliminate edge bright spots. The diffusion plate 6 adopts laser micro-engraving + chemical polishing technology to achieve a surface roughness of Ra < 0.1 μm, and the light forms a Lambertian distribution when passing through, and after testing, UGR < 13 (international glare value standard).

[0028] The light source module 7 selects high-color-rendering (Ra≥98) LED lamp beads, which are connected in parallel through quick plug-in terminals. The modular design is convenient for replacement. The light source module 7 is fixed to the inner side of the aluminum ring 5 through spring screws, and the distance between the light-emitting surface and the diffusion plate 6 is optimized to 2 - 3 cm through optical testing to avoid direct light leakage.

[0029] The inner wall of the aluminum ring 5 is sprayed with a high-reflectivity coating (reflectivity ≥ 95%). The light source module 7 emits light upward. After being reflected by the inner wall of the aluminum ring 5, it is diffusely reflected downward through the diffusion plate 6, avoiding direct light into the eyes and improving the light efficiency utilization rate.

[0030] The aluminum ring 5 is treated by micro-arc oxidation to form a 20μm ceramic layer, with a surface hardness reaching HV800 and passing the 48-hour salt spray test (ASTM B117).

[0031] During the design process, through simulation with optical simulation software (such as LightTools), the prism angle of the diffusion plate and the light source spacing are optimized and designed to be 45° - 60°, so that the main light output angle is controlled within 120° - 150°, forming a soft and uniform surface light source effect.

[0032] The light source module 7 is hidden inside the aluminum ring 5. The light source arrangement spacing of the light source module 7 is 15 - 20mm. The spacing between the light output surface of the light source module 7 and the diffusion plate 6 forms a light-shielding angle of ≥ 30°. Combined with the diffuse reflection of the diffusion plate 6, the surface brightness of the lamp is ≤ 1000 cd / ㎡, meeting the CIE anti-glare standard.

[0033] Through precise testing, such as integrating sphere spectral analysis, the particle density of the diffusion plate 6 and the light source arrangement spacing are adjusted and set to 15 - 20mm, so that the uniformity of the light output surface of the lamp is ≥ 0.85, avoiding bright and dark light spots.

[0034] The color temperature of the LED light source module 7 is adjustable from 2700K to 5600K. It is arranged in a 30° inclined angle annular array inside the aluminum ring, so that the light source is hidden. Cooperating with the three-pronged steel wire rope 4 to form a suspension space distance of 15 - 25mm, ensuring that the light is first projected onto the ceiling and then reflected, avoiding direct light into the eyes. Verified by optical simulation, when the distance between the light source and the ceiling is 1 / 8 of the lamp diameter (for example, for a φ600 lamp, it is 75mm), the reflection efficiency can reach 92%.

[0035] This ceiling lamp adopts a precision manufacturing process, and the key dimensions adopt ISO 2768-m level precision, such as:

[0036] The length tolerance of the steel wire rope 4 is ±0.1mm;

[0037] The flatness of the diffusion plate 6 is < 0.05mm / m;

[0038] The installation angle deviation of the light source module 7 is ±0.5°.

[0039] The control module is integrated inside the ceiling lamp. The control module is equipped with a mobile phone APP, which can remotely adjust the brightness, achieve 0 - 100% linear dimming, color temperature from 2700K to 5600K, preset "reading", "watching movies", "night light" scene modes, and support timed switching and adaptive light sensing adjustment.

[0040] The control module integrates Wi-Fi / Bluetooth dual-mode chips, supports access to mainstream smart platforms (such as Mijia and Tuya), supports multi-device linkage, and has built-in ambient light sensors and infrared receiving modules to sense ambient light in real time and respond to commands. It supports timer switch and countdown functions, and automatically adjusts the brightness in combination with the ambient light sensor (such as automatically increasing the illumination under strong light during the day and reducing the brightness at night).

[0041] The control module can realize remote control, monitor the status of lamps in real time through the APP, support multi-device group management, and is compatible with voice assistants (such as Xiao Ai and Siri). The system automatically records user usage habits (such as common time periods and brightness preferences), intelligently recommends scene modes, and improves energy saving rate by more than 30% compared with traditional lamps.

[0042] The interaction is as follows:

[0043] Mobile APP control: supports remote adjustment of brightness (0-100% linear dimming), color temperature (2700K-5600K), and monitoring of lamp status.

[0044] Voice control: Compatible with mainstream voice assistants such as Xiao Ai and Siri to achieve "contactless" operation.

[0045] Scene mode:

[0046] Reading mode: high illumination (500-700lx), cool white light (5000K), the diffuser angle is optimized to concentrate the light;

[0047] Movie viewing mode: low illumination (50-100lx), warm yellow light (3000K), diffuse reflection ratio increased to 90%, reducing screen reflection;

[0048] Night light mode: dim light (10-30lx), moonlight white (4000K), turn on anti-blue light mode to protect night vision.

[0049] Custom mode: Users can save personalized light parameters (such as office mode, parent-child mode, etc.) according to their needs.

[0050] The CIE TN 006-2016 visual comfort model is introduced to dynamically adjust the PWM frequency to above 3000Hz to ensure that the flicker index is <5% (IEEE Std 1789-2015).

[0051] After the production of this ceiling lamp, it is tested and verified:

[0052] 1. Optical performance test

[0053] Use Yuanfang Photoelectric Goniophotometer (GOS-600) to measure the light intensity distribution and glare value (UGR) to ensure that UGR ≤ 19, in line with the no-glare standard;

[0054] The luminous efficacy (lm / W) tested by the integrating sphere is ≥100, the color rendering index Ra≥98, and R9≥80, meeting the high illuminance requirements.

[0055] 2. Structural reliability test

[0056] Wire rope load-bearing test (loading 5 times the rated weight, no deformation after 24 hours);

[0057] High and low temperature cycling test (-20°C - 50°C, 50 cycles) to verify the weather resistance of the power supply and light source module;

[0058] Mechanical vibration: passing the IEC 60068-2-6 standard (5 - 500 Hz, 30 minutes for each of the 3 axes); Luminous decay test: L70>54000 hours (estimated by TM-21).

[0059] 3. Intelligent control test

[0060] Wireless connection stability (distance ≤10m, passing through 3 walls), command response delay ≤0.5 seconds;

[0061] Ambient light sensor accuracy test (error ≤±5 lx) to ensure the accuracy of automatic dimming;

[0062] Intelligent response: network delay <80 ms (test with 100 devices in parallel).

[0063] The functional principle of the present invention can be described through the following operation methods:

[0064] In the present invention, the LED light source module (with adjustable color temperature of 2700K - 5600K) is arranged in a circular array with a 30° tilt angle on the inner side of the aluminum ring, so that the light source is arranged in a hidden manner. The ceiling lamp is installed on the ceiling through the cooperation of the hanging plate 1 and the ceiling plate 2, and a suspension space distance of 15 - 25 mm is formed in cooperation with the three-pronged wire rope to ensure that the light is first projected onto the ceiling and then reflected, avoiding direct light into the eyes, and controlling the main light output angle within 120° - 150°, forming a soft and uniform surface light source effect.

[0065] It can be used in the following scenarios:

[0066] Home scenario: The hanging height of the lamp can be adjusted according to the decoration style (for example, hanging height of 2.2m for minimalist style and 1.8m for Nordic style), and the diffusion plate angle can be adjusted to achieve the switching between focused and diffused light.

[0067] Commercial scenario: In offices / classrooms, the height can be adjusted to adapt to different desktop illuminance requirements (for example, when the desk illuminance needs 500 lx, the hanging height of the lamp is adjusted to 1.5m).

[0068] This ceiling lamp can be quickly adjusted without tools, has independent three-way calibration, and has a compact structure without being exposed, taking into account both practicality and aesthetics, and is superior to traditional fixed suspension or complex pulley systems. It meets the differentiated lighting needs in multiple scenarios such as home, office, and education. Voice control reduces the operation threshold for the elderly and children, and the remote monitoring function can view the lamp status in real time (such as whether it is turned off), reducing potential safety hazards.

[0069] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
