Our Story

Early 1990s Founding Period
Our company was founded in 1987 as MR Electronics by Chairman Min-Ro Yoon, and in 1991 by CEO Chang-Ro Yoon as MR Engineering, started a full-scale lighting control business.
At that time in the 1990s, modernized buildings were being constructed as modernized buildings with the introduction of the Intelligent Building System. At that time, our company was installing advanced technology in Korea, acting as a Korean agency for the US GE TLC system.
In the early days, the lighting control market in Korea was a competition for Japanese products (Panasonic & Toshiba) and American products (GE & Lutron). At that time, for price competitiveness, our company received technology from GE and installed our system in large projects such as Incheon Airport and COEX mall through localization of some products, and began to receive favorable reviews from customers in Korea.
GE, a global company, no longer develops technology for the item of lighting control system, so in the early 2000s, we succeeded in developing a technology that combines Korean technology with the existing GE lighting control technology solution. In 2002, SmarTLC and Smatrol software were developed and exported back to GE. Also, in 2012, we finally released the ELC system developed with pure technology, and we launched products such as SLC, MLC, and ILC on the market.

2012, ELC System Release
ELC System is a system that can solve the trials and errors experienced while continuously releasing products applying the technology of US GE TLC. ELC stands for Excellent Lighting Control.
This system configures each control device as a separate Stand Alone type system, and connects them to the same network for interlocking control when necessary.
In the other words, the On/Off System and the Dimming System are operated separately, and they are connected on one network so that they can serve as complementary devices. Each system in configured not to have a lot or a small number of address, addresses from 000 to a maximum of 999.
Switches are also composed of various types, so that each switch type can be composed of 000~999 addresses.
In the On/Off system, it is configured of various control modules (4sRM, 6sRM, 4eRM), and these devices are composed of 000~999 addresses, allowing configuration from small projects to large projects.
In the Dimming System, it consists of various models such as 0-10 Dimming Module (8 Channels), DALI Dimming System, and Wireless Dimming System.
The design of the ELC System referred to the European model, and adopted a compact and smart configuration and practical American style functions.

Recent Markets in 2020
As the LED lighting market has recently changed to smart lighting, our lighting control system is recognized as a company that can provide a variety of systems, and is receiving favorable reviews for its excellent products from various customers.

Early on, LDM (LED DALI Dimming Module) system that adopted the DALI communication method was installed mainly in large projects such as the KEPCO Naju office building, the Sejong City Government Building, and the 2nd Lotte World Tower. It is recognized for its excellence that surpasses global competitors for its stability and convenient function implementation of the installed system.
In addition, Wireless Dimming System and 0-10V Dimming System of wireless method are also connected to one network of the existing ELC System. As the only system capable of interlocking control by integrating the existing On/Off system and DALI system, it is gaining attention at home and abroad.
These technologies can be thought of as the result of developing and integrating newly emerging technologies one by one with the existing system even after the development of the existing system.

As for the existing lighting control system, the On/Off system using Latching Relay was applied to most buildings.
However, as lighting fixtures changed from fluorescent lamps to LED lighting, this LED lighting began to apply wired/wireless Dimming Modules capable of individual dimming. Now most new projects have begun to install this individually controlled system for each luminaire. But, the problem is that in the case of a large project, tens of thousands of LED lights are started to be controlled by individual dimming scenes one by one, marking it difficult to maintain a properly stable system in the range of communication problems and software processing capabilities.
We were also able to solve such communication problems and software processing capabilities one by one by actually experiencing these parts.

Recent, RLCM (Room Lighting Control Management) Release
Recently, MRBAS has launched a small projects or RLCM (Room Lighting Control Management) with Room unit control concept. This system does not require a computer or software. When the switch, relay module, sensor, and LED individual dimming module are connected to the existing LAN cable. The basic program is automatically set while recognizing the mutual address of each device, and general individual, group, and scene control is possible. If the user wants to modify the program, it is possible to change the program on the switch or on a smart phone that is automatically paired with the switch through BLE communication. This RLCM system can be easily installed in small-sized offices, conference rooms, shopping malls, restaurants and public places, so it is expected to be spread in the market as a practical lighting control product.

This year, MRBAS intends to present the existing LEVEL-3 system; ELC System and new product LEVEL-2 system; RLCM at the international exhibition “LIGHT+BUILDING” in Frankfurt, Germany and “LIGHT FAIR” in Las Vegas, USA. Due to the COVID-19 outbreak, all exhibition were canceled, and entries in the international exhibition of our new products and existing products were canceled.

We are trying to show our products to customers in various ways through this website. We promise to further complement our non-face-to-face online service through various technical data and video files. MRBAS, which always develops and services systems from the perspective of customers.
Thank you for your continued interest and support.
