Title:
DISCHARGE LIGHTING AND DISCHARGE LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039031
Kind Code:
A1
Abstract:
This discharge lighting (1) comprises base sections (11, 12) and a discharge tube (13) containing electrodes (13a, 13b). The base sections have terminals (11t, 12t) for establishing connection to external power source lines (15a, 15b), and internal power source lines (20a, 20b) for connecting the terminals to the electrodes (13a, 13b) inside the discharge tube. Provided in the base sections are information generation devices (24a, 24b) for generating information to be sent to the exterior. Provided in the base sections are superposing circuits (27a, 27b) by which the information generated at the information generation devices are superposed in the internal power source lines within the base sections. The information generation devices contain sensors (25a to 26b) for detecting the environment inside or around the base sections, and generate information based on the outputs from the sensors. From the external power source line that is connected to the internal power source line, a reception circuit (16) extracts and receives the information superposed in the internal power source line. According to this configuration, information generated on the lamp side can be sent to the exterior with a simple constitution.
