What the claims cover, in plain language

Claim 1 defines an outdoor portable lamp comprising a lamp cover, hollow support bar, reflective base, and power box. The support bar connects the cover and base detachably. The cover contains a circuit board at the top and a movable frame at the bottom holding an LED lamp tube. A dust-proof plate is fixed to the LED tube’s inner ring, with a power connector on top. The reflective base has a lower groove containing an angle changing device and a light absorbing column. The absorbing column is fixed to the groove’s bottom wall.

Claim 2 specifies the cover has support chips and a handle bar, plus a heat release hole for thermal management. Claim 3 details the angle changing device: a reflector bonded to the groove wall, with an arc strip and deflecting item welded to its inner ring. Claim 4 describes the light absorbing column having a lifting groove and pull bolt, allowing vertical adjustment. Claim 5 notes the power box is a ring box with a charge port and switch, connected to the base center. Claims 6-8 elaborate on the lifting mechanism, including compensating tanks, docking blocks, and locking rings to secure the absorbing column’s position.

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. It has no US or other foreign counterpart.

Before tooling starts, two issues deserve a closer look:

  • Freedom to operate. Portable LED lighting is a crowded field, with many utility patents covering dimming circuits, battery management and optical diffusers. Buyers should commission a freedom-to-operate (FTO) review of their chosen driver, cell pack and diffuser before a US launch, so the mechanical light-absorption design can be checked against live claims.
  • Component Sourcing. The “light absorbing column” and “angle changing device” require precise molding and assembly. Verify that your supplier can achieve the tolerances needed for the smooth vertical movement described in Claim 4.

Customization and manufacturing

What can be customized

AreaOptions
Battery CapacityPower box size can vary to hold different cell counts (e.g., 18650 vs 21700).
LED TypeCCT (color temperature) and CRI (color rendering index) of the LED tube.
MaterialsHousing can be ABS, PC, or aluminum alloy depending on weight/cost targets.
Absorption MechanismMaterial of the absorbing column (opaque plastic vs. semi-translucent silicone).
InterfaceUSB-C vs. Micro-USB charging ports; button vs. touch switch.

Things to plan for (US market)

  • UL 1598 / UL 8750 - Safety standards for electric lamps and LED equipment. Essential for retail sales.
  • FCC Part 15 - Electromagnetic interference compliance for the electronic driver and any wireless features.
  • California Prop 65 - Warning requirements for certain chemicals in plastics and electronics sold in CA.
  • CPSC Regulations - General consumer product safety rules apply, though specific toy/children’s product rules do not unless marketed to kids.

How a project runs

  1. Inquiry - Define target brightness, battery life, and material preferences.
  2. Design - Finalize the mold geometry for the reflective base and absorbing column mechanism.
  3. Prototype - Build samples to test the mechanical absorption effectiveness and electrical safety.
  4. Certification - Submit for UL/FCC testing.
  5. Production - Injection molding, PCB assembly, final assembly, and packaging.

Quantities & timeline

Tooling for the complex reflective base and movable frame requires high-precision molds. Lead times depend on certification queue lengths. Send us your target specifications, quantity, and timeline and we will reply with options.
