Garden Pest Control Lamp with Rainwater Cleaning and Irrigation

The problem

Outdoor garden lamps often serve two separate purposes: illumination and pest control. Traditional bug traps accumulate dead insects quickly, requiring regular manual cleaning, which is difficult when the lamp is mounted high or in remote garden areas. Additionally, many garden setups lack an efficient way to utilize natural resources like rainwater for irrigation. Separating these functions leads to higher maintenance costs and missed opportunities for sustainable water use.

The solution

This design combines a mosquito-repellent lamp with a self-cleaning and irrigation system.

1. A street lamp base (1) supports a vertical bracket (2).
2. At the top, a water collecting frame (3) captures rainwater.
3. Below this, a mosquito-repellent mechanism (4) hangs from a sliding sleeve (44).
4. Two air cylinders (43) drive the sliding sleeve, adjusting the height of the lamp shades (41).
5. Under the shades, repellents (42) attract and kill insects.
6. A cleaning mechanism (5) sits below the shades. It includes a first collecting frame (52) where dead insects fall.
7. Rainwater from the top flows into this frame, washing the debris into a discharging mechanism (6).
8. A spraying mechanism (7) with a screening mechanism (8) filters the water for plant irrigation.

Who it is for

• Landscape architects designing integrated smart-garden fixtures that reduce maintenance needs.
• Garden equipment brands looking to differentiate their lighting products with eco-friendly features.
• Municipal park managers who need durable, low-maintenance pest control solutions for public spaces.
• Homeowners with large yards seeking automated ways to manage mosquitoes without constant manual cleaning.

How it works

The main parts

Operating steps

1. Attraction: At night, the lamp shades (41) emit light. Insects fly toward the light due to phototaxis.
2. Elimination: The electric repellent devices (42) kill the approaching insects.
3. Collection: Dead insects fall by gravity into the first collecting frame (52).
4. Height Adjustment: Air cylinders (43) extend or retract to move the sliding sleeve (44), changing the coverage area.
5. Cleaning: During rain, water collected in the top frame (3) flows down into the collecting frame (52), washing away accumulated insects.
6. Discharge: The discharging mechanism (6) helps clear the washed debris.
7. Irrigation: Filtered water passes through the screening mechanism (8) and is sprayed by the watering cans (73) onto nearby plants.

Applications

Residential Gardens

Homeowners can install this lamp near patios or flower beds. It reduces mosquito bites during evening hours while keeping the trap clean automatically when it rains.

Public Parks

Municipalities can deploy these units along walkways. The self-cleaning feature reduces labor costs for maintenance crews who would otherwise need to empty traps manually.

Agricultural Greenhouses

Growers can use the integrated irrigation function. The lamp controls flying pests near crops, and the filtered water can help maintain humidity or irrigate seedlings in controlled environments.

Resort Landscaping

Hotels and resorts benefit from the aesthetic integration. The device provides lighting, pest control, and plant care in a single fixture, enhancing guest experience without visible clutter.

Where it is less suitable

• Indoor Use: The rainwater collection and discharge systems are designed for outdoor exposure.
• High-Wind Areas: The adjustable height mechanism may require additional stabilization in extreme weather conditions not specified in the patent.
• Pure Lighting Needs: If pest control and irrigation are not required, standard LED garden lights are simpler and cheaper.
