What the claims cover, in plain language

Claim 1 defines the core structure: a mounting bracket and at least two parallel light-emitting components. Each component has a lamp panel and a heat sink with a mounting groove. Crucially, a power supply is placed inside each heat sink’s groove and connected to the panel. Adjacent brackets are movably connected by a folding assembly.

Claim 2 specifies that the heat sink includes an upper cover plate, riveted onto the mounting groove, positioned above the lamp panel, with the power supply arranged on the inner wall of this cover.

Claim 3 details the folding assembly: it comprises first and second rotating shaft supports, a movable shaft, screws, and nuts. The supports have axisymmetric rotating holes. The shaft passes through them to allow rotation, secured by the screw and nut.

Claim 4 adds a connecting piece to the folding assembly, passing through positioning holes on the supports.

Claim 5 identifies the connecting piece as a knob screw for manual adjustment.

Claim 6 describes the heat sink including a setting element (locking clip) that engages the ends of the mounting groove, with a bent extension forming a draw-in groove.

Claims 7-10 cover further details on the locking engagement, sealing pieces on the bracket ends, and the electrical connector configuration linking the parallel power supplies.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed only in China and is currently active in China. It has no US or other foreign counterpart.

Two points to settle early:

  • Other patents may exist. The field of modular LED horticulture lighting is competitive, with many US patents covering various driver integration methods, heat dissipation structures, and folding mechanisms. A freedom-to-operate (FTO) review is strongly recommended before launching a similar product in the US market to ensure no infringement of existing US utility or design patents.
  • Driver Certification. Integrating the power supply directly into the metal heat sink requires careful thermal management and electrical safety compliance, which differs from external driver designs.

Customization and manufacturing

What can be customized

AreaOptions
Module CountConfigurable number of light bars (2, 3, 4+) per fixture.
SpectrumFull spectrum white, red/blue mix, or UV/IR addition depending on LED chip choice.
Heat Sink MaterialSPCC cold-rolled steel (as patented) or aluminum extrusion for lighter weight.
Folding AngleRange of motion limited by the shaft and stopper design; adjustable via knob tension.
ConnectivityStandard AC plug, USB-C, or hardwired terminal block options.
FinishPowder coating colors, black/white matte, or raw metal.

Things to plan for (US market)

  • UL 8750 / UL 1598: Safety standards for LED equipment and luminaires. Integrated drivers must meet creepage/clearance requirements within the confined space of the heat sink.
  • FCC Part 15: Electromagnetic interference compliance for the switching power supplies inside each module.
  • DLC Listing: For commercial rebates, the product may need to qualify for the DesignLights Consortium listing, requiring specific efficacy and lifespan testing.
  • California Title 20: Energy efficiency regulations for lighting devices sold in California.

How a project runs

  1. Inquiry - Define target lumens, spectrum, module count, and folding requirements.
  2. Design - Engineer the heat sink cavity to fit the chosen driver PCB, design the hinge tolerances, and layout the electrical connections.
  3. Prototype - Build samples to test thermal performance (driver temp vs. ambient), folding durability, and light output uniformity.
  4. Pilot Run - Produce small batch for reliability testing (on/off cycles, drop tests) and certification submission.
  5. Production - Stamp/form heat sinks, assemble drivers, rivet covers, install LEDs, and assemble folding brackets.

Quantities & timeline

Manufacturing involves precision stamping for the SPCC steel heat sinks, injection molding for plastic covers/connectors, and SMT assembly for the integrated drivers. The folding mechanism requires machined or stamped shafts. Tooling lead time depends on the complexity of the heat sink die. Send us your lumen target, spectrum preference, module count, quantity and target price and we will reply with options.
