What the claims cover, in plain language

Claim 1 - a multifunctional insect-expelling lamp comprising a street lamp base (1), a bracket (2), a water collecting frame (3), a mosquito-repellent mechanism (4), and a cleaning mechanism (5). The bracket holds the water collector and the repellent mechanism. The repellent mechanism includes a sliding sleeve (44) on the bracket, lamp shades (41), fixing rods (45) holding repellents (42), and air cylinders (43) that move the sleeve up and down. The cleaning mechanism includes rod pieces (51), a collecting frame (52) slidably connected to the rods, and a spring (53). It also includes a discharging mechanism (6) with fixing parts, contact blocks, and springs to clear debris. Additionally, a spraying mechanism (7) with a second collecting frame and watering cans, and a screening mechanism (8) with a screen and reel assembly, are included for filtering and dispensing water.

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 in force. Making or selling this specific configuration in China requires the owner’s permission. However, since there are no corresponding patents in the US or Europe, the technology itself is not restricted by this patent in those markets.

Two points to settle early:

  • Other patents may exist. While this specific combination of rainwater cleaning and insect killing is patented in China, other US patents may cover individual components such as electric grid killers, motion-sensor lights, or specific irrigation nozzle designs. A freedom-to-operate (FTO) review is recommended before mass production for the US market.
  • Component Sourcing. The air cylinder mechanism for height adjustment is a key functional element. Standard pneumatic components may vary in size and mounting interfaces compared to the custom brackets described in the patent.

Customization and manufacturing

What can be customized

AreaOptions
MaterialAluminum alloy or stainless steel for the bracket and base for corrosion resistance.
Light SourceUV LED arrays for maximum insect attraction; energy efficiency ratings.
Power SupplySolar panel integration, battery backup, or hardwired AC power.
DimensionsHeight range adjusted by cylinder stroke length; shade diameter for coverage area.
FinishPowder coating colors to match garden aesthetics (green, black, bronze).
Water SystemCapacity of the collecting frame; nozzle type for the spraying mechanism.

Things to plan for (US market)

  • UL 1598 / UL 8750 - Safety standards for luminaires and LED equipment. Electrical components must meet strict insulation and fire safety requirements.
  • IP Rating - Must achieve IP65 or higher for outdoor durability against rain and dust ingress.
  • EPA/FCC - If wireless connectivity (e.g., app control) is added, FCC certification is required. Note: This patent describes a mechanical/electrical system, not necessarily a smart-connected one.
  • California Prop 65 - Screening of materials for lead, mercury, or other regulated substances in electronics and coatings.

How a project runs

  1. Inquiry - Define power source, dimensions, and material preferences.
  2. Design - Adapt the bracket geometry for local electrical codes and component availability.
  3. Prototype - Build functional samples to test water flow, cleaning efficiency, and structural stability.
  4. Pilot Run - Small batch production for field testing in various weather conditions.
  5. Production - Injection molding for plastic parts, metal fabrication for frames, and final assembly.

Quantities & timeline

Tooling for the custom sliding sleeves and water channels will require precision molds. Metal brackets can be laser-cut and bent. Certification testing for electrical safety adds time to the schedule. Send us your target dimensions, power requirements, material choices, quantity and target price and we will reply with options.
