Ring-Shaped Outdoor Lantern That Lifts Off a Power-Bank Charging Base

The problem

Outdoor lights for patios, gardens and campsites are either fixed - plug-in or solar lights that stay in place - or portable lanterns that must be remembered and charged separately. A carried lantern is usually set down on the ground or table, where it tips over, and its small battery runs out in an evening. The patent’s aim is a light that is easy to take along when needed, with longer run time through a charging port and a storage battery.

The solution

The patent splits the light into a lamp (100) and a lamp holder (200):

1. The lamp is a ring with a round cross-section: a handle (110) at the bottom and a lampshade (120) at the top, with the light tube inside the shade.
2. A first battery inside the handle powers the light. A charging hole (111) on the underside of the handle and a switch (112) on its front complete the lamp.
3. The holder has a cone-shaped base (210) with a groove on top. A charging plug (211) in the groove matches the lamp’s charging hole, and magnetic blocks (400) are set into both sides of the groove.
4. A second battery in the base acts as the charging source for the lamp. A second switch (213) connects or disconnects it, and a second charging hole (212) recharges the base.
5. A clamping piece (220) moves between a clamping and an unlocked state; clamped, it forms a slot (230) with the base that holds the lamp, unlocked, the lamp can be put in or taken out.
6. A lamp group mounts several lamps and holders together (figure 5).

Who it is for

• Outdoor and camping lighting brands wanting a lantern with a home-base charging dock as its key selling point.
• Patio and garden furniture companies - the patent’s current owner is a furniture maker - who sell coordinated outdoor lighting.
• Hospitality suppliers providing table lights for restaurant terraces, hotel gardens and event venues, where lamps are collected and recharged nightly.
• Home décor brands selling cordless table lamps for indoor-outdoor use.

How it works

The main parts

Using it

1. Charge the base through its charging hole.
2. Dock the lamp - set the handle into the groove so the plug enters the charging hole, then close the clamp.
3. Use it as a table light in the base, switching the lamp on at its handle.
4. Lift it off - open the clamp and carry the ring by its handle, or hang it from a hook or branch.
5. Return it to the base to recharge from the base battery or from mains.

Applications

Patio and deck tables

A cordless table light that stays upright in its base during dinner and can be lifted off to walk guests to the gate.

Camping and RV trips

The base stays in the tent or van as a charging station; the ring lantern goes to the campfire or hangs from a tree.

Restaurant and hotel terraces

Staff collect lamps at closing and dock them; a group plate keeps several lamps charged in one place.

Power-outage backup

Kept docked at home, the lamp is always charged and lifts out instantly when the power fails.

Garden parties and events

Groups of lamps on a shared plate can line a path or a buffet, then be carried away individually.

Where it is less suitable

• Permanent garden lighting - lights that stay out year-round are better served by hard-wired or solar fixtures.
• Heavy-duty work lighting - this is a décor and leisure lantern, not a high-output site light.
