Automatic light induction switch street lamp using acousto-optic controlled detection within 3-5 metre sensing range for 220V mains voltage in white colour
AS-20 Series Automatic Street Lamp with 3-5 Metre Acousto-Optic Induction Range

The AS-20 series automatic induction street lamp offers responsive lighting activation through its integrated detection system. Designed for street and outdoor area illumination, this unit operates on standard 220V mains voltage, making it suitable for municipal and commercial lighting applications. Its white-coloured housing provides a neutral appearance that blends with various architectural environments while the acousto-optic controlled induction mechanism ensures reliable activation when movement or sound occurs within its designated range.
Features and Construction

This street lamp belongs to the AS-20 product series and is categorised as Type 0 within that range. The construction centres around its automatic induction functionality rather than physical dimensions or specific material composition details.
Material and Build
The product features a white-coloured exterior housing that contains the induction electronics and lighting components. While specific construction materials aren't detailed in the source text, the unit is designed for outdoor street lighting applications, suggesting appropriate weather resistance for its intended environment.
Size and Practical Fit
The available specifications focus on technical performance rather than physical measurements. The 3-5 metre sensing range determines the effective coverage area for activation, while the 220V working voltage indicates standard mains electrical compatibility. These specifications help determine appropriate installation spacing and electrical requirements.
Uses and Placement

The automatic induction functionality makes this street lamp suitable for locations requiring energy-efficient, responsive lighting without constant manual control or continuous operation.
Event or Professional Use
For commercial or municipal applications, the AS-20 can provide cost-effective street lighting that activates only when needed. The 3-5 metre acousto-optic detection range offers practical coverage for pathways, building perimeters, or security areas where movement-triggered lighting enhances safety while reducing energy consumption compared to continuously illuminated fixtures.
Everyday Home Use
For residential properties, this automatic street lamp can illuminate driveways, garden paths, or entrance areas when visitors approach. The white colour provides a neutral aesthetic that complements various exterior décors while the automatic function eliminates the need to remember to switch lights on or off manually.
Benefits and Buying Value

The AS-20 series street lamp offers practical advantages through its specific technical configuration and automatic operation principle.
Reuse and Low Maintenance
The induction-based operation reduces energy consumption by only illuminating when the 3-5 metre range detects activity. This automatic functionality means the fixture requires minimal daily intervention once installed, with the acousto-optic controlled system handling activation without manual switching.
Why Choose This Product
This street lamp provides a specific technical solution combining 220V operation with acousto-optic induction within a defined 3-5 metre range. The white colour offers visual neutrality while the AS-20 series designation indicates a specific product category within automatic lighting options. For applications requiring movement-activated street lighting with standard voltage compatibility, this unit provides those precise capabilities.
