Description

Smart LED luminaire with built-in wireless flasher and fault monitor {LED Light Fixture with Wireless Flasher and Fault Monitor}

The present invention relates to an LED luminaire, and more particularly, to improve the structure of the luminaire to be installed on the road, and to manufacture a unit with a built-in wireless flasher and fault monitor, economical and usability is improved, remote control is possible and when a failure occurs It relates to a smart LED luminaire that can cope quickly.

In general, road lighting such as street lights or security lights are installed on roads or sidewalks for the purpose of preventing various accidents and further preventing crime by securing a view of a driver or a pedestrian in a dark night or a poor visibility.

These lighting facilities are managed by installing a large number of lights in a relatively large area, and should be turned on or off according to the time, the management of the lighting time and off time of the street lamp need to be managed accurately in order to prevent waste of energy. In addition, it is necessary to check for malfunctions and failures during the use of the lighting system.

However, because the fan is distributed and installed in a space, it is difficult to control the lighting and turn off the lighting and check the state of the lighting, malfunction and failure due to the nature of the lighting facility that is not easily accessible to users or administrators.

Therefore, instead of turning on and off the lamps by hand manually, the lamp is turned off by remote control by auto or wireless. According to the “Guidelines for Inspection of Street Lights and Security Lights” of the Korea Electrical Safety Corporation, street lamps are controlled by wireless remote control. It is configured to turn on and off automatically. In addition, for this purpose, a separate wireless flasher is attached to the street lamp (column) during the existing street lamp installation.

Accordingly, the conventional luminaires and street lamps are prepared by installing the existing LED street lamps and general flashers, respectively, and the street lamps and the flashers must be purchased separately when the product is installed, and they must be installed at the time of construction.

 In addition, in the communication network for automatic flashing, the conventional CDMA method has a problem of disconnection of the RF network due to the low power wireless communication, and when the radio repeater fails, the function of the individual WIFI / Zigbee terminal connected thereto is limited.

In addition, when using CDMA and LTE wireless repeaters / amplifiers, the communication cost burden is rather large (50,000 ~ 60,000 won a year), and only the Group type can be installed, resulting in low efficiency. There are inefficient problems in terms of purchase cost and management as products to be equipped with a wireless repeater.

(2) SMPS Failure Determination: It is designed to measure whether ACV LINE is connected to SMPS (in / out) and current or voltage, and transmit the measured value to MCU to determine.

＊ Designed to transmit the measured value to MCU by DCV line connected to D / C LED module and SMPS from sensor part that can measure DCV supply (in / out) and current or voltage.

＊ In the above structure, when ACV is checked in the sensor part, but when it is confirmed that the DCV supply is cut off, the MCU first judges the SMPS as a failure and then the sensor measurement value by the temperature and illuminance sensor part and the sensor of ACV / DCV. The measured value is compared and analyzed to design the exact fault part.

(3) Failure Determination of Wireless Communication Unit: Design MCU to enable software algorithm self-diagnosis

＊ Self-diagnosis content: 미 Under RSSI value to measure wireless sensitivity of wireless communication, increase of wireless noise level, inability to transmit / receive signal to / from base station (repeater) due to coverage problem due to simultaneous connection, Check for poor grounding.
