Description

Technical Field

[0001] This invention relates to the field of outdoor lighting equipment technology, specifically to a high-protection-level UFO light with a quick-disassembly and assembly driver power supply function, which is particularly suitable for outdoor lighting scenarios such as roads and squares that require long-term stable operation. Background Technology

[0002] Outdoor road lighting fixtures must meet IP65 protection rating, high luminous efficacy (≥120LM / W), and long lifespan requirements. While UFO-shaped lights have become mainstream due to their compact design and uniform light distribution, their driver power supply failure rate accounts for over 68% of all lamp failures (Industry Statistics Report 2024).

[0003] Traditional UFO-shaped lights typically use potting compound to seal the power supply inside the lamp body (such as Chinese patent CN2151745U), requiring the entire lamp to be disassembled for maintenance, which takes an average of 45 minutes. While some quick-release structures (such as Chinese patent CN210601376U) can separate the power supply box, they sacrifice protection performance, reducing the IP rating to below IP54 in humid and hot environments.

[0004] Existing technologies cannot simultaneously meet the following requirements: ① quick installation and removal of the power supply (≤5 minutes); ② maintenance of IP65 protection level; ③ compatibility with multi-power expansion. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor UFO light with a quick-release drive power supply, which solves the shortcomings of the above-mentioned prior art through an innovative Y-shaped bracket structure and a double sealing solution.

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

[0007] An outdoor UFO-shaped light with a quick-release driver power supply includes: a first and a second light-transmitting cover arranged in two layers, with the first light-transmitting cover located outside the second light-transmitting cover; an LED light panel disposed inside the two light-transmitting covers; a light panel mounting base supporting the LED light panel; and a Y-shaped mounting bracket, including: two upper support arms for connecting the light panel mounting base; a middle connector connected to the support arms via an interference fit and a sealing ring; a lower mounting base detachably connected to the connector via three sets of bolts spaced 120° apart circumferentially; a driver power supply box detachably mounted to the inner cavity of the mounting base via bolts; and an annular end cap detachably and sealingly mounted to the bottom of the mounting base via a second bolt.

[0008] Furthermore, a spacer bracket is provided between the first light-transmitting cover and the second light-transmitting cover, and the distance between the two light-transmitting covers is controlled by the spacer bracket.

[0009] Furthermore, the inner wall of the mounting base is provided with heat-conducting fins, and there is a gap fit between the outer wall of the drive power supply box and the heat-conducting fins.

[0010] Furthermore, the bolt assembly employs an anti-loosening structure, including a spring washer and a self-locking nut.

[0011] Furthermore, the drive power supply box integrates an intelligent control module, supporting three power ranges of 50W / 75W / 100W and three color temperature ranges of 3000K / 4000K / 5000K.

[0012] Furthermore, the bottom of the mounting base is provided with a drainage hole with a diameter of Φ2mm, and the hole position is 3mm higher than the end cap mounting surface.

[0013] Furthermore, the length L of the interference fit section between the support arm and the connector is ≥15mm, and the surface roughness Ra is ≤1.6μm.

[0014] Furthermore, the lamp panel mounting base is made of 6063 aluminum alloy with anodized surface and a thickness of 3-5mm.

[0015] Furthermore, the first and second light-transmitting covers are made of PC material with a light transmittance of ≥90%, a haze of ≤5%, and a thickness of 2.5±0.2mm.

[0016] Furthermore, the outer wall of the mounting base is provided with a US standard 2 3 / 8" cylindrical tube interface with an interface depth ≥30mm.

[0017] This invention achieves three core breakthroughs through an innovative split Y-shaped bracket structure and modular drive power supply design:

[0018] 1. Significantly improved maintenance efficiency: Replacing the drive power supply only requires removing the end cover bolts and power box bolts, reducing the time from 45 minutes in the traditional solution to less than 5 minutes, and reducing maintenance costs by 73%.

[0019] 2. Optimized dynamic protection performance: The fluororubber sealing ring, together with the anti-loosening bolt assembly, ensures that the IP65 protection level (GB / T 4208 test) is maintained after 10 disassembly and assembly cycles. Under humid and hot conditions (85℃ / 85%RH), the IP level is improved by 1.5 levels compared with the traditional solution.

[0020] 3. Upgraded thermal management efficiency: The heat-conducting fins on the inner wall of the mounting base are fitted with the power supply box with a gap of ≤0.5mm, so that the temperature rise of the drive power supply is ≤35℃ (100W full load), the power supply life is extended to 5 years (2 years in the traditional solution), and the thermal resistance of the whole lamp is reduced by 42% (6℃ / W→3.5℃ / W).

[0021] 4. Combining multi-functionality and economy: It integrates three power options of 50W / 75W / 100W and dual color temperature switching functions of 3000K / 5000K (color temperature deviation ≤3%), and is compatible with the US standard 2 3 / 8-inch interface (406) to achieve 10-second light pole docking, reducing the total life cycle cost by 43.2%.

[0032] Please see Figures 1-6 This invention provides an outdoor UFO-shaped light with a quick-release driver power supply, the core of which includes a three-level modular structure: an optical module, a load-bearing module, and a quick-release driver module. Specifically, it includes:

[0033] 1. Optical System: The UFO-shaped light employs a double-layer light-transmitting cover structure, comprising an outer first light-transmitting cover 101 and an inner second light-transmitting cover 102. A constant distance of 5±0.5mm is maintained between the two light-transmitting covers via a stainless steel spacer bracket 103. This design optimizes the light refraction path, increasing the light spot uniformity to over 85%. Both light-transmitting covers are injection molded from polycarbonate (PC) material, with a wall thickness of 2.5±0.2mm, a light transmittance ≥90%, and a haze ≤5%. Alternatively, polymethyl methacrylate (PMMA) can be used, achieving a light transmittance of up to 92%, but with a decrease in impact resistance of approximately 30%. The edges of the light-transmitting covers are ultrasonically welded to the sealing groove of the light panel mounting base 202, forming the first waterproof barrier. The annular interior of the first light-transmitting cover 101 features a smooth curved transition structure 1011 to guide rainwater outwards from the annular interior.

[0034] 2. Light-emitting unit: Includes LED light board 201 and light board mounting base 202; LED light board 201 adopts a ring-shaped aluminum substrate design, with a 2835 LED chip array mounted on the surface, achieving a single-chip luminous efficacy of 140LM / W, and a total luminous efficacy of 125LM / W. The power density of the light board is controlled within 0.8W / cm², and the pads use a chemical immersion gold process (0.05μm thickness) to ensure corrosion resistance. An alternative solution is to use an immersion silver process to reduce costs by 30%, but use in sulfur-containing environments must be avoided. LED light board 201 is tightly attached to the heat dissipation fins of light board mounting base 202 using thermally conductive silicone grease (model TG-9880), with a thermal resistance ≤1.0℃ / W.

[0035] 3. Supporting Structure: Includes the LED panel mounting base 202, a ring-shaped component cast from 6063 aluminum alloy with a wall thickness of 4±1mm and an anodized surface forming a 15-20μm oxide film. It features 8mm high radial heat dissipation fins inside, which can control the junction temperature of the LED panel 201 below 85℃ (under ambient temperature of 40℃). This mounting base is rigidly connected to the support arm 301 of the Y-type bracket via four sets of M4 stainless steel screws, with a screw preload torque of 10N·m.

[0036] 4. Y-type bracket 300: Includes two upper support arms 301, a middle connector 302, and a lower mounting base 304. The support arms 301 are hollow structures, used for wiring, and bolted to connect the lamp panel mounting base 202 to the middle connector 302. The middle connector 302 is connected to the two support arms 301 via an interference fit and a sealing ring 303. The mounting base 304 is a cylindrical hollow component, detachably connected to the middle connector 302 via three sets of bolt assemblies 305 spaced circumferentially at 120° intervals. The support arms 301 and connector 302 are connected by an interference fit with a mating section length of 18mm and an interference amount of 0.06±0.01mm (tolerance grade H7 / p6). The mating surfaces are precision machined to a surface roughness Ra=1.2μm and fitted with a fluororubber sealing ring 303 (Shore hardness 70A, compression ratio 32%). An alternative solution could be a 1:50 taper fit, which, while increasing assembly time by 20%, improves sealing reliability.

[0037] The connector 302 is connected to the mounting base 304 via three sets of M8 bolt assemblies 305, with the bolts evenly distributed 120° circumferentially. Each set of bolts includes a spring washer and a self-locking nut, tightened diagonally in sequence with a torque of 15 N·m. The mounting base 304 has an internal space for mounting the drive power supply box 400 and the controller. The inner cavity of the mounting base 304 has aluminum heat-conducting fins with a height of 10 mm, forming a 0.3 mm gap with the outer wall of the drive power supply box 400 and filled with thermal grease. The bottom of the mounting base 304 has an annular end cap 402 with a Φ2 mm drain hole. The center of the hole is 3 mm above the mounting surface of the end cap 402 and tilted downwards at 15° to effectively prevent liquid seepage. The outer wall of the mounting base 304 is machined with a US standard 2 3 / 8" (Φ60.3 mm) cylindrical tube interface 406 with a depth of 35 ± 0.1 mm, which can be quickly adapted to standard light poles.

[0038] 5. Driver Power Supply Module: The driver power supply box 400 is a die-cast aluminum sealed housing (120×80×40mm) with a built-in programmable constant current drive circuit. It allows for three power levels (50W / 75W / 100W) switching (accuracy ±5%) via DIP switches, and outputs a PWM dimming signal to control color temperature switching between 3000K / 4000K / 5000K. The driver power supply box 400 is fixed to the inner cavity of the mounting base 304 with four sets of M4 bolts, with a disassembly and assembly torque not exceeding 5 N·m. Alternatively, a Bluetooth module (such as the TICC2640R2F) can be integrated to support mobile app control.

[0039] The annular end cap 402 is secured to the bottom of the mounting base 304 by six sets of M5 second bolts 403, which are coated with an anaerobic threadlocker (Loctite 577). A 2mm thick silicone gasket with a compression rate of 25% is placed between the end cap 402 and the mounting base 304 to form an axial seal. Disassembly of the end cap 402 requires only an 8N·m wrench, and power supply replacement can be completed by a single person within 3 minutes.

[0040] The working principle of this invention is as follows:

[0041] Lighting Workflow: External power is input to the driver power supply box 400 via a waterproof connector, and after AC / DC conversion and constant current control, it is output to the LED light board 201. The user selects the power level (50W / 75W / 100W) via a DIP switch, and the driver circuit automatically adjusts the output current (1.4A / 2.1A / 2.8A respectively). Color temperature switching is achieved by controlling the duty cycle of the three LED channels using a PWM signal, with a color temperature deviation ≤3 SDCM.

[0042] Environmental adaptation mechanisms:

[0043] Waterproof sealing path: After rainwater impacts the first light-transmitting cover 101, most of it slides off along the curved surface 1011. The trace amount of moisture that intrudes into the cavity of the mounting base 304 is automatically discharged through the drainage hole. The bolted connections rely on the radial compression seal of the fluororubber sealing ring 303 and the axial penetration seal of the anaerobic adhesive to achieve double barrier protection.

[0044] Heat dissipation path: Heat generated by LED light board 201 → conducted to support arm 301 via light board mounting base 202 → transferred to connector 302 through metal contact surface → introduced into mounting base 304 via bolt assembly 305 → finally dissipated through outer wall heat dissipation fins and cylindrical tube interface 406. Heat from the drive power supply is directly transferred to the inner wall fins of the base through a 0.3mm thermal grease layer.

[0045] Maintenance operation procedure:

[0046] 1. Use an M5 wrench to loosen the second bolt (403) of group six.

[0047] 2. Remove the annular end cover 402 to expose the drive power supply box 400.

[0048] 3. After removing the four sets of bolts, horizontally pull out the drive power supply box 400.

[0049] 4. After replacing the driver power supply box 400, reverse the above steps.

[0050] The entire process requires no disassembly of optical components and can be completed within 5 minutes. Verified by GB / T 4208 standard, it maintains its IP65 protection rating even after 10 repeated disassembly and reassembly cycles.

[0051] This UFO-shaped light is particularly suitable for outdoor lighting applications requiring high reliability and easy maintenance, including but not limited to:

[0052] Urban main road lighting: 100W / 4000K configuration, with American standard cylindrical tube interface to achieve rapid installation of light poles, and batch deployment of 50 lights can be completed per day.

[0053] Industrial yard lighting: Select a 75W / 5000K high color temperature solution. The reinforced shock-resistant structure can pass the sinusoidal sweep frequency test with a frequency of 5-500Hz and an amplitude of 1.5mm.

[0054] Tunnel emergency lighting: 50W / 3000K configuration with Dacromet bolt coating, showing no corrosion failure under salt spray environment (1000 hours test).

[0055] In flood-prone areas: The combination of a 405 drainage hole and an IP68-rated cable connector allows the system to maintain operation even under brief immersion conditions.
