Rotating Garden Light with Integrated Mosquito Repellent and Self-Cleaning Features

The problem

Traditional garden lighting fixtures have static beams, meaning large areas often require multiple poles and wiring runs to achieve uniform coverage. Furthermore, outdoor lamps accumulate dust, pollen, and bird droppings quickly, which significantly reduces light output over time. Cleaning these fixtures is labor-intensive, especially when mounted high on poles. Mosquitoes are also attracted to many light sources, creating discomfort for people using the space nearby. Existing solutions typically address these problems separately—using bug zappers, separate fans, or requiring manual maintenance schedules—which increases complexity and cost.

The solution

This design integrates three functions into one mechanical unit driven by a single motor located in the base.

1. Main Rotation: A motor in the fixing seat drives a vertical pole via a gear and belt system. This causes the entire upper assembly, including the connecting plate and lamp holder, to rotate around the central axis.
2. Mosquito Repellent Assembly: Attached to the rotating connecting rod are specific plates. As the main structure rotates, these plates are driven by a secondary transmission system (belts and gears) to spin independently. The movement generates localized airflow intended to discourage mosquitoes from settling near the light.
3. Cleaning Assembly: Linked to the same rotational drive is a bidirectional screw rod mechanism. As the lamp rotates, this rod turns, causing a mounting ring equipped with cleaning cotton to move vertically along the guide rods. This action wipes the outer surface of the lamp body, keeping it clear of obstructions.

Who it is for

• Landscape Architecture Firms: Designers looking for low-maintenance, multi-functional fixtures for parks, resorts, and private gardens where reducing service visits is a priority.
• Municipal Parks Departments: Agencies responsible for public green spaces that need efficient lighting coverage with fewer poles and automated cleanliness features.
• Residential Developers: Builders of high-end homes with large backyards who want premium amenities like integrated pest deterrents and self-maintaining lighting.
• Hospitality Venues: Hotels and restaurants with outdoor seating areas that benefit from reduced insect interference and cleaner-looking fixtures for guests.

How it works

The main parts

Operating steps

1. Power On: The motor (42) inside the base begins to turn.
2. Primary Drive: The motor drives a first belt and gear set, which rotates the vertical pole (3).
3. Head Rotation: The rotating pole carries the connecting plate (5) and lamp holder (7), causing the light beam to sweep across the area.
4. Secondary Transmission:
   • One path drives the insect repellent plates (93) via a second belt and gear system, making them spin against the air to generate wind.
   • Another path drives the cleaning assembly (10) via a third belt and a bidirectional screw rod (105).
5. Cleaning Action: The screw rod’s rotation moves the cleaning cotton (103) up and down the exterior of the lamp body (8), wiping away debris.
6. Continuous Cycle: These actions repeat as long as the light is on, providing dynamic illumination, pest deterrence, and self-maintenance simultaneously.

Applications

Public Park Pathways

Park managers can install fewer poles because the rotating light covers a wider arc. The self-cleaning feature reduces the frequency of ladder-based maintenance crews needed to keep pathways bright and safe.

Resort Outdoor Lounges

Guests enjoy evening relaxation without the nuisance of mosquitoes hovering around the lights. The continuous cleaning ensures the fixtures look pristine, enhancing the aesthetic appeal of luxury hospitality environments.

Residential Backyards

Homeowners benefit from a “set and forget” lighting solution. The automated cleaning prevents the dimming effect caused by dust accumulation, while the repellent function makes outdoor dining more comfortable without chemical sprays.

Agricultural or Garden Centers

Greenhouses and nurseries often have high humidity and dust levels. This lamp maintains its light output automatically, supporting plant growth monitoring or display visibility without frequent manual intervention.

Where it is less suitable

• Indoor Spaces: The mechanical noise and airflow generation are designed for open-air environments and may be disruptive indoors.
• High-Wind Areas: While the design uses wind for repellency, extreme storms might damage the moving parts or destabilize the rotating mass if not properly anchored.
• Fixed-Direction Requirements: If a project requires precise, static spotlighting on a specific object, the sweeping motion of this lamp would be inappropriate.
