Lighting system and signal converting device therefor
First Claim
1. A lighting system, comprising:
- a lighting apparatus including a plurality of LEDs;
a driver configured to drive the plurality of LEDs;
a sensor unit configured to generate an environment information by detecting a change of surrounding environment; and
a controller configured to control the driver based on the environment information,wherein the controller comprises a signal converter communicatively connected to the driver via a wireless communication connection operating according to a wireless communication protocol and a digital addressable lighting interface (DALI) master controller configured to transmit and receive a signal according to a DALI communication protocol, andwherein the signal converter is configured to inter-convert a signal transmitted to and received from the DALI master controller according to the DALI communication protocol and a signal transmitted to and received from the lighting driver according to the wireless communication protocol so as to enable communication between the driver and the DALI master controller.

Abstract
A lighting system includes a digital addressable lighting interface (DALI) master controller, a lighting driver, and a signal converter. The DALI master controller is connected to a management server. The lighting driver operates a lighting device including a light emitting diode (LED). The signal converter is connected to the DALI master controller by a DALI bus operating according to a DALI communication protocol, and is communicatively connected to the lighting driver via a wireless communication connection operating according to a wireless communication protocol. The signal converter inter-converts a signal transmitted and received from the DALI master controller according to the DALI communication protocol and a signal transmitted to and received from the lighting driver according to the wireless communication protocol so as to enable communication between the lighting driver and the DALI master controller.
