Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a convenient LED lighting module that is compatible with multiple scenarios. Background Technology

[0002] Current LED lamp module designs are generally large, integrated units, which can only fit lamp housings of fixed sizes and shapes. They cannot be flexibly adjusted to suit the installation space and shape requirements of different lamps, limiting application scenarios. In existing technologies, the lamps in these large modules are connected in series or centrally. If some lamps fail, the entire module must be replaced, resulting in significant material waste and high repair costs. Furthermore, the centralized installation of the entire module leads to concentrated heat accumulation during lamp operation, which cannot be quickly dissipated. Prolonged use can cause overheating and aging of the module, affecting its lifespan. From an installation and usage perspective, existing large modules are heavy, requiring considerable effort to install, and are difficult to disassemble by a single person, making installation cumbersome.

[0003] Even for lamps with some parallel light source modules, such as the LED hall lamp with a parallel light source module circuit disclosed in the utility model patent with publication number CN203215487U, the module is still a long strip centralized design, which cannot flexibly adapt to the housing of irregular lamps such as skylights and chandeliers, and there is also the problem of inconvenient installation. Utility Model Content

[0004] The technical problems to be solved by this utility model are limited compatibility, high maintenance costs, cumbersome installation and operation, potential electrical safety hazards, and poor heat dissipation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model proposes a convenient replacement LED lighting module that is compatible with multiple scenarios, including a lamp housing assembly, and several independently set LED sub-modules, a low-voltage power supply unit and a circuit connection structure disposed within the lamp housing assembly.

[0007] Several LED sub-modules are connected in parallel through a circuit connection structure to form a light source assembly. Each LED sub-module can be distributed according to the outline of the lamp housing assembly and a preset topology rule. The LED sub-modules and the lamp housing assembly are detachably connected through a convenient installation structure.

[0008] The low-voltage power supply unit is electrically connected to the light source assembly and is used to convert external mains power into an extra-low safety voltage of 24V / 36V and power the LED sub-module.

[0009] Preferably, the lamp housing assembly includes a chassis, an aluminum frame, and an arc-shaped light-transmitting cover. The chassis is provided with a first mounting hole for fixing to the building roof and a second mounting hole adapted to the LED sub-module, which is used to support the LED sub-module and circuit connection structure. The aluminum frame is fixed to one end of the chassis, and the arc-shaped light-transmitting cover is sleeved on the outside of the aluminum frame. The arc-shaped light-transmitting cover is made of light-transmitting material and is used to perform secondary light distribution and diffusion of the emitted light from the LED sub-module.

[0010] Preferably, the first mounting hole is provided with a rubber nail and a self-tapping screw for fixing to the building roof surface, and the position of the second mounting hole corresponds to the preset topology rule for physical positioning of the LED sub-module. The LED sub-module is fixed to the second mounting hole by multiple washer screws.

[0011] Preferably, the convenient installation structure is a combination of a magnetic suction component and a thermally conductive adhesive layer. The magnetic suction component includes a permanent magnet fixed to the back of the LED sub-module and a metal adsorption component fixed to the second mounting hole. The thermally conductive adhesive layer is made of high-temperature resistant silicone and is disposed between the permanent magnet and the back of the LED sub-module, serving both as a fixation and auxiliary heat dissipation function.

[0012] Preferably, the number of LED sub-modules is 8 to 20, arranged in a ring array, matrix array, or irregular array with adaptive contours; each LED sub-module is an on-board structure, integrating 4 to 24 LED chips arranged in an array. Assuming the rated voltage of the LED chips is 6V, they are connected in series in 4 strings (adapted to 24V power supply) or 6 strings (adapted to 36V power supply) within a single LED sub-module.

[0013] Preferably, the LED chips within a single LED sub-module are connected in series to form a series branch that matches the 24V or 36V power supply voltage.

[0014] Preferably, the low-voltage power supply unit includes an AC-DC conversion circuit, which is adapted to 110V / 220V AC mains power input and outputs 24V / 36V constant voltage DC power, with a rated output power range of 30W to 100W.

[0015] Preferably, the circuit connection structure includes:

[0016] The circuit board has LED chips mounted on it, and corresponding input terminal IN and output terminal OUT are provided on it. The input and output terminals are used to realize the parallel electrical connection of each LED sub-module.

[0017] The drive control chip is mounted on the chassis and electrically connected to the circuit board and each LED sub-module. It is used to adjust the drive current or pulse width modulation signal of the LED chip.

[0018] The protection circuit is electrically connected to the drive control chip and the power input side, and includes at least filtering, voltage regulation and reverse connection protection components, such as resistor R1, capacitors C1-C2 and diode D1, to realize voltage regulation, filtering and reverse connection protection of the circuit.

[0019] Preferably, the drive control chip has multiple independent control channels, each channel being connected to one or more LED sub-modules to achieve grouped or independent dimming and color adjustment control of the LED sub-modules. Pins 2-7 of the drive control chip U1 are electrically connected to the control terminals of the LED chips, and pins 1 and 8 are electrically connected to the positive and negative terminals of the power supply, respectively, for realizing grouped control of the LED chips.

[0020] Preferably, it also includes a controller, which is communicatively connected to the low-voltage power supply unit and the circuit connection structure, and is used to send instructions to the drive control chip to realize the switching control, brightness adjustment and color temperature switching of the lamp module.

[0021] The present invention proposes a convenient LED lighting module that is compatible with multiple scenarios. The beneficial effects achieved by adopting the above structure are as follows:

[0022] 1. This solution, through its replaceable housing components and flexible distribution of LED sub-modules, can adapt to various lighting fixtures such as skylights, chandeliers, and wall lights. There's no need to redevelop an entire module for different lighting fixtures; only the aluminum frame and light-transmitting cover of the corresponding shape need to be replaced, significantly improving the product's scene coverage. The distributed layout of the LED sub-modules can also adapt to the installation space of irregularly shaped lighting fixtures, breaking the adaptation limitations of traditional integrated modules.

[0023] 2. This solution uses 24V / 36V extra-low voltage power supply, which can completely avoid the risk of high voltage electric shock and improve the safety performance of use, whether it is installation and commissioning, daily maintenance or long-term use.

[0024] 3. Based on the screw hole, a magnetic attraction combined with thermally conductive bonding installation structure is proposed, which is easy to disassemble, and the parallel connection method will not affect the normal lighting of other modules, reducing the trouble of maintenance.

[0025] 4. The distributed design of LED sub-modules avoids the concentrated accumulation of heat. Combined with the thermally conductive adhesive layer and the auxiliary heat dissipation of the aluminum frame, it effectively avoids the problems of light decay of LED beads and aging of the module caused by high temperature, thus extending the service life.
