How RS485 lighting control system works
Think of an RS485 smart lighting control system as a smart, responsive computer network that gives light. In general, Yibai’s RS485 control system connected lighting system consists of three main levels or layers: hardware installed in the illuminated space, software accessible via the cloud, and optional services from our company.

Hardware
The RS485 lighting control system uses both lighting hardware and networking hardware. In illuminated spaces, connected LED luminaires, while sensors of various kinds collect data from the illuminated environment. Behind the scenes, lighting controllers and standard networking devices afford connectivity and integration.
Software
The cloud-based platform serves the full range of software applications for lighting management, monitoring, and control. Collected data is stored in the cloud, along with analysis and visualization tools for turning data into insight.
Supports from Yibai Company
Professional, managed, and lifecycle services from Yibai LED lighting offers such aids as system audit and design, remote system management and maintenance, UV-C disinfection, and light as a service, where you buy the light, not the lighting.
Hardware-Melo series LED Street Light
- Melo Series LED Street light is fully optimized to become your long-term lighting and innovation partner. Thanks to its future-proof system ready architecture, the use of optimized Lumileds LED and optical platform ensuring best in class lighting performance in a broad range of applications. It also offers improved serviceability.
- The installation has also become easier and faster, also the cable feed-through has been redesigned and access to the gear components is easy thanks to top down tool-less access.
- Melo offers all connectivity and dimming options available today and thanks to being system ready, it can also be paired with lighting management systems such as Smart City or existing and upcoming sensor innovations.
- Melo has been developed to optimize and simplify spare part repair and maintenance work using a new plug & play module containing all electrical components in an easy to handle and accessible box inside the housing.
- As a company conscious about the impact of light on the environment and biodiversity, we also equipped the Melo family with dedicated light recipes that help with maintaining the optimal ecosystems for bats or preserve a dark night sky.
