Wireless Lighting Control Improves Accessibility
Who Is Thabiso Matsemela?
Thabiso Matsemela is an engineering technician with the Free State Department of Public Works and Infrastructure. He grew up in Botshabelo, near Bloemfontein, and earned a master’s degree in electrical engineering from the Central Technical University, where he was named the top master’s student in his faculty. Besides his technical work, Matsemela is a fellow of the department and has already gained national acclaim for his innovative projects.
The Challenge Faced by Elsonia Swarts
Elsonia Swarts, a colleague who uses a wheelchair, struggled to reach the light switch in her office. The switch was mounted on the ceiling and wired directly to the bulb, making it impossible for her to turn the lights on or off without assistance. This inconvenience often left the lights on unnecessarily, wasting electricity and creating frustration.
How the New System Works
Matsemela designed a wireless lighting control system that replaces the hard‑wired switch with a battery‑powered remote. The remote sends a signal to a small receiver installed near the light fixture, which then toggles the power to the bulb. Because the remote can be placed on a desk or attached to a wheelchair, Swarts can operate the lights without needing to stretch or ask for help.
Benefits for the Workplace and the Environment
- Independence: Swarts now controls her office lighting on her own terms, improving her comfort and productivity.
- Energy Savings: By being able to turn lights off when she leaves the room, the department reduces unnecessary power consumption.
- Cost Reduction: Lower electricity use translates into savings on utility bills, which can be redirected to other service improvements.
- Inclusivity: The solution demonstrates how simple technology can remove physical barriers and create a more welcoming work environment.
Recognition and Awards
Before this lighting project, Matsemela received national attention for an integrated alarm and energy‑management system that automatically shuts off equipment like air conditioning, heating, and lighting when a building is empty. That invention earned him the Trailblazer Award in 2022 from the Center for Public Service Innovation. His latest work continues to highlight his talent for blending practical engineering with social impact.
Looking Ahead: Inclusive Tech in Government
Matsemela believes that accessible technology should be a standard consideration in public‑sector projects. He hopes his wireless lighting control will inspire other departments to adopt similar solutions, ensuring that employees of all abilities can perform their jobs efficiently and comfortably.
Conclusion
The wireless lighting control developed by Thabiso Matsemela is more than a convenient gadget—it is a step toward a more inclusive workplace. By giving Elsonia Swarts easy access to her office lights, the system enhances her daily work life, saves energy, and showcases how thoughtful engineering can address real‑world challenges. As the Free State Department of Public Works and Infrastructure continues to support innovators like Matsemela, the future looks brighter for everyone.
