Abstract

The LED lighting device installed in each parking area of the outdoor parking lot comprises: a main lighting unit for lighting a corresponding parking area; an auxiliary lighting unit provided separately from the main lighting unit to display different colors according to ranges of available parking spaces of the corresponding parking area; and a camera for detecting the number of available parking spaces by photographing the corresponding parking area. According to the present invention, the auxiliary lighting unit for displaying a different color according to the number of parking spaces is provided besides the main lighting unit to display whether parking is available in the parking area where the LED lighting device is installed and to simultaneously display the number of vehicles which can be parked with a different color for each range, so that users can easily check an available parking area.

First claim

What is claimed is:

1 . A light-emitting diode (LED) lighting device installed in each parking area of an outdoor parking lot, the LED lighting device comprising:
a main lighting unit configured to light a parking area; an auxiliary lighting unit provided separately from the main lighting unit to show a different color depending on a range of a number of available parking spaces of the parking area; and a camera configured to detect the number of available parking spaces by photographing the parking area.

2 . The LED lighting device of claim 1 , further comprising:
a parking space determining unit configured to periodically receive an image captured by the camera, to compare the image with a reference image to determine the number of available parking spaces, and to cause a lighting controller for controlling the auxiliary lighting unit to recognize the number of available parking spaces.

3 . The LED lighting device of claim 1 , further comprising:
a communication unit configured to transmit an image captured by the camera to a central control room and to deliver information about a number of available parking spaces of the parking area determined by the central control room to the lighting controller for controlling the auxiliary lighting unit.

4 . The LED lighting device of claim 2 , further comprising:
a camera driving unit configured to rotate the camera to photograph the entire parking area.

5 . The LED lighting device of claim 2 , further comprising:
a charging battery and a charging controller configured to perform charging in hours corresponding to low electricity charges.

6 . The LED lighting device of claim 5 , further comprising:
a power generation unit configured to generate power to charge the charging battery.

7 . The LED lighting device of claim 6 , wherein the power generation unit is a photovoltaic power generation device or a wind power generation device.

8 . The LED lighting device of claim 6 , further comprising:
a base station device unit for supporting communication of a mobile communication terminal.
