Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a smart control frameless ultra-thin ceiling light structure with multiple modes of dimming and color adjustment. Background Technology

[0002] As a mainstream product in modern home lighting, ceiling lights typically consist of a light-transmitting cover, an LED light source module, a heat dissipation base, and mounting components. With the general decrease in ceiling height in living spaces and the rise of minimalist interior design styles, the market has placed core demands on ceiling lights, including ultra-thin designs (thickness ≤ 30mm), frameless full-light-emitting surfaces, and intelligent light environment adjustment. Traditional ceiling lights, in order to achieve structural strength and heat dissipation performance, often employ a reinforced metal frame design, resulting in a limited light-emitting area (edge ​​luminous efficiency loss rate > 15%) and the creation of dust accumulation dead zones. Furthermore, conventional dimming and color-changing solutions rely on dedicated remote controls or mobile apps, making them incompatible with the building's pre-installed wall switch systems.

[0003] Current mainstream technologies have significant limitations: for example, the "framed ceiling light" disclosed in Chinese patent CN2114243U has an aluminum alloy frame that results in a lamp thickness of 45mm, and a dark area is formed at the joint between the frame and the light-transmitting cover; while the "dual-color temperature ceiling light" described in patent CN2108919U can switch between 3000K and 6000K, it requires an additional signal receiving module and cannot be directly controlled by a physical switch. More importantly, the existing products suffer from a lack of variety in installation methods—the three mainstream installation structures, namely ceiling-mounted, pendant-mounted, and rod-mounted, usually require different lamp bodies, and users need to disassemble and reassemble the entire lamp when changing the installation mode, which contradicts the demand for convenience in modern homes.

[0004] Analysis revealed that existing technologies struggle to simultaneously resolve three major contradictions: ① the contradiction between ultra-thin structure and heat dissipation performance (reduced thickness leads to insufficient heat dissipation area), ② the contradiction between frameless design and installation strength (removing the frame results in a lack of load-bearing points for hanging installation), and ③ the contradiction between intelligent control and electrical compatibility (low integration of multi-protocol dimming circuits). Therefore, there is an urgent need to develop a core technology solution integrating an ultra-thin frameless structure, a wall-mounted switch direct-control intelligent dimming system, and a multi-installation mode adaptive mechanism to fundamentally improve the product's overall performance and user experience. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent control frameless ultra-thin ceiling light that solves the problems of light efficiency loss, limited installation scenarios, and single control functions caused by the structural limitations of traditional ceiling lights.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart, frameless, ultra-thin ceiling light includes a light-transmitting cover assembly, an LED light source module, a lamp body, a driver power supply, and a mounting plate.

The lamp body has a first mounting portion for supporting the LED light panel and driver power supply, and a second mounting portion for supporting the LED light strip; a circular groove is designed at the center of the top surface of the lamp body. The driver power supply is built into the first mounting portion; the mounting plate is embedded in the circular groove; and radially distributed heat dissipation fins are provided on the bottom surface of the first mounting portion.

[0008] Furthermore, the LED light panel includes multiple concentric circles of LED chip arrays, and the radial distribution of the heat dissipation fins corresponds to the arrangement of the concentric circles of the LED chip array.

[0009] Furthermore, the first light-transmitting cover is connected to the first mounting part of the lamp body through a circumferentially distributed snap-fit ​​structure; the second light-transmitting cover is connected to the second mounting part of the lamp body through a bolt group.

[0010] Furthermore, a sealing gasket is provided between the second light-transmitting cover and the lamp body.

[0011] Furthermore, the mounting plate includes a circular base plate and mounting ears located on the edge of the base plate; the mounting plate is interlocked with the lamp body via a quick-release latch.

[0012] Furthermore, the circular substrate is provided with circular hanging holes and arc-shaped hanging grooves of various sizes.

[0013] Furthermore, the driving power supply is equipped with dual output interfaces that independently control the LED light board and the LED light strip; the lamp body has wire channels that communicate with the dual output interfaces.

[0014] Furthermore, the top surface of the lamp body is provided with a hidden hook mounting groove.

[0015] Furthermore, it also includes a safety lanyard attached to the back of the lamp body.

[0016] The beneficial effects of this invention are as follows:

[0033] Please see Figures 1-8 This invention provides an intelligent control frameless ultra-thin ceiling light, including a light-transmitting cover assembly 1, an LED light source module 2, a lamp body 3, a driver power supply 4, and a mounting plate 5. The light-transmitting cover assembly 1 consists of a first light-transmitting cover 11 with a circular central area and a second light-transmitting cover 12 with a conical curved surface structure arranged around the first light-transmitting cover. The first light-transmitting cover 11 is an optical-grade PMMA injection-molded flat plate with a diameter of 300mm, a thickness of 1.5mm, and a light transmittance of ≥92%. Its edges are injection-molded with 12 sets of clips 111, which are used to connect to the lamp body 3. The second light-transmitting cover 12 is made by a two-color injection molding process, with an outer transparent PC substrate (0.8mm thick) and an inner vacuum-plated aluminum reflective film. The second light-transmitting cover 12 is connected to the lamp body 3 by bolt assembly 121. An EVA material sealing gasket 6 is set between the second light-transmitting cover 12 and the lamp body 3 to achieve IP44 protection, passing a 30-minute water spray test (IEC60529).

[0034] An LED light source module 2 is installed between the lamp body 3 and the light-transmitting cover assembly 1, comprising a circular LED light panel 21 and an annular LED light strip 22. The LED light panel 22 uses a 2oz copper-thick aluminum substrate (thermal conductivity 220W / m·K), and is equipped with 10 concentric arrays of 2835 LED chips. The inner ring has 24 LEDs with a color temperature of 5000K, while the outer ring has 78 LEDs with a color temperature of 1800K, arranged in a gradient pattern, with a total power of 36W. The LED light panel 22 consists of multiple groups of LED chips with a ring width of 30mm, and the surface is coated with a 3:1 mixture of KSF red phosphor and β-SiAlON green phosphor, with a constant color temperature of 1800K. An isolation gap is provided between the LED light panel 21 and the annular LED light strip 22 to prevent light interference.

[0035] The lamp body 3 is an aluminum component made of ADC12 aluminum alloy die-casting (tensile strength 310MPa), used to install the light-transmitting cover assembly 1, LED light source module 2, driver power supply 4, and mounting plate 5. The lamp body 3 includes a first mounting part 31 and a second mounting part 32. The central first mounting part 31 is circular with a diameter of 150mm, and multiple heat dissipation fins 33 are radially distributed on the bottom surface. Ventilation slots 34 are formed between the heat dissipation fins 33. The height of the heat dissipation fins 33 increases gradually from 2.0mm on the inner circle to 3.0mm on the outer circle. The base of the heat dissipation fins 33 can be filled with paraffin-based phase change thermal paste (containing 30wt% aluminum nitride nanoparticles) to further enhance heat dissipation. The second mounting part 32 on the outer periphery of the lamp body 3 is an annular platform. A circular groove 35 is machined into the center of the top surface of the lamp body 3 for arranging the mounting plate 5. Three sets of quick-release slots 36 are machined into the sidewall of the circular groove 35 for connecting the mounting plate 5.

[0036] The mounting plate 5 is fixed in the circular groove 35 by a mechanical quick-release locking structure. The mounting plate 5 includes a circular base plate 51 and three mounting ears 52 arranged on the outer edge of the base plate 51. The mounting plate 5 is laser-cut from 2mm thick SPCC steel plate, and the three sets of mounting ears 52 on the edge are formed by stamping and bending. The quick-release slot 36 includes a slot 361 slightly wider than the mounting ears 52 and a lock 362. After the mounting plate 5 is inserted into the groove 35, it is rotated so that the mounting ears 52 are engaged in the slot 361 and embedded in the groove 35. The mounting plate 5 is rotated further to align the mounting ears 52 with the lock 362 to achieve interlocking. The base plate 51 has circular mounting holes 511 and arc-shaped mounting grooves of various sizes to adapt to the installation requirements of different scenarios. To facilitate the rotation and installation of the mounting plate 5, a circular mounting hole 513 is provided in the center of the base plate 51. For ease of installation, a safety lanyard 6 can be installed on the back of the lamp body 3, allowing for convenient hanging of the lamp during installation. The safety lanyard 6 is made of nylon braided rope or steel wire rope with a tensile strength ≥500N. One end has a hanging loop, and the other end is fixed to the back of the lamp body 3. Furthermore, a rotatable hook 7 can be embedded and installed on the back of the lamp body 3 via a hidden slot 37.

[0037] The driver power supply 4 is built into a sealed cavity between the lamp body 3 and the first light-transmitting cover 11. The main control circuit uses a TICC2652R Bluetooth SoC and a dual-channel PWM driver chip. The dual output interfaces 8 are connected to the LED light board 21 and the LED light strip 22 respectively through wires. The wire channels are potted with epoxy resin (thermal conductivity 1.2W / m·K) to achieve IP44 protection. The control logic responds to the wall switch operation: a single click starts the main light mode (first light board 100% power), a double click switches to the night light mode (second light board 20% power), and a long press triggers a 1800K-5000K color temperature cycle.

[0038] The working principle of this invention is as follows: When the ceiling light is connected to 220V / 50Hz mains power, the user triggers the control signal through a wall switch. In the main lighting mode, the chip array of the LED light panel 21 emits high color temperature white light, which penetrates perpendicularly through the microprism structure of the first light-transmitting cover 11, forming a uniform illuminance of 800-1200lx in the center of the lighting area; in the ambient light mode, the chip array of the LED light strip 22 emits warm light, which diffuses along the normal direction of the second light-transmitting cover 12 after total reflection by the reflective film, forming a soft halo of 150-200lx at the edge. When the dual modes are mixed, the driving power supply 4 independently adjusts the duty cycle of the two PWM channels (frequency 1.8kHz) to achieve stepless transition of color temperature and gradual change of brightness. The heat dissipation system starts simultaneously: the heat generated by the LED chip is conducted to the phase change heat conduction layer through the aluminum substrate, and the thermal shock is absorbed at the 55℃ phase change point; the heat dissipation fins 33 distribute the heat dissipation area according to the heat flux density, and achieve thermal balance with the air convection of the ventilation slots 34, ensuring that the chip junction temperature is ≤85℃ when the 36W full load is applied. During installation, first embed the mounting plate 5 into the circular groove 35 of the lamp body 3, and rotate the base plate 51 to make the quick-release locking tongue engage with the groove 35 to complete the mechanical locking; the hoisting component can be adjusted to a horizontal angle of ±30° by passing through the arc-shaped hanging groove 52; the hidden hook 7, together with the installation hanging rope 6, can withstand a pulling force of 50kgf without displacement.

[0039] This ceiling light, an embodiment of the invention, is particularly suitable for modern homes and commercial spaces with ceiling heights exceeding 2.4m. In residential settings, its 28mm ultra-thin design reduces thickness by 40% compared to traditional light fixtures, and its frameless shape complements minimalist interior design styles. In commercial spaces, dual-mode independent control meets the high illuminance requirements of office areas and the ambient lighting needs of rest areas. In high-humidity environments such as bathrooms, it benefits from an IP44 protection rating and has passed a 2000-hour durability test at 95% humidity. Actual optical performance measurements show that the main light mode achieves a luminous efficacy of 120lm / W (LM-79-19 standard), a color temperature adjustment range of 1800K-5000K (ANSI C78.377 tolerance ±50K), and an edge lighting uniformity improved to 0.87 (traditional products ≤0.68). The heat dissipation system keeps the chip junction temperature stable below 85℃ (IEC 60598-1), with an expected lifespan of 50,000 hours (calculated using IES TM-21). The installation system utilizes a mechanical quick-release latch, reducing installation time to 5 minutes (a 75% improvement in efficiency according to GB / T 33721 testing). Vibration testing (IEC 60068-2-6) verified no structural loosening under various modes. This technical solution, through the innovative combination of a double-body structure for the light-transmitting cover, zoned control of the light source, a gradient heat dissipation system, and a quick-installation mechanism, solves the three major technical bottlenecks of traditional ceiling lights: dark edges, insufficient heat dissipation, and complex installation.
