Description

Smart lighting device that can save energy {

The present invention relates to a lighting device, and more particularly to a lighting device that can save energy.

As interest in energy saving increases, a technology for controlling the brightness of various light bulbs, which used only on / off control in a batch, is being developed. As an example, a technique for controlling the brightness of a light emitting bulb by controlling the amount of power supply has already been proposed. In this technology, the brightness of the light bulb is controlled by changing the power provided to the light bulb that generates light to 5W, 10W, 30W, and so on. However, since the lighting bulb has an appropriate power intensity set in advance at the time of manufacture, it is difficult to change the light intensity, that is, the brightness according to the size of the power supply, to the lighting bulb having a different power intensity.

In particular, in the case of street lamps installed on the road, the lighting is turned on and off according to the installed position, and only the control of the lighting time is long in winter and the lighting time is short in summer. This is a control method to improve the convenience in collective management rather than to improve the efficiency of energy. Furthermore, in order to simplify the control, there is a method of controlling each street lamp with a remote controller. In this case, only one street lamp or all street lamps installed in a specific area can be controlled by one operation. Therefore, it is possible to alternatively control the lighting / lighting off of the street light, but there is an inconvenience that the administrator must turn on / off the corresponding street light while walking around.

The present invention is to solve such a problem, it is an object of the production of a lighting device capable of adjusting the brightness more easily.

According to a further aspect of the invention, a lighting device according to the invention is characterized by storing a user-defined program and controlling the on / off of the switch according to the stored program.

According to another aspect of the present invention, the lighting device according to the present invention checks whether the ID matches the ID information included in the received data according to ID information given to the plurality of lighting devices belonging to the group. Select only the command to execute.

In addition, it is possible to monitor the operation of the street lamp through a web camera installed in the lighting device and to receive the data in real time from a remote terminal, so that the remote control method can quickly cope with the malfunction of a lighting device such as a street lamp or failure of a component. have.

The intelligent lighting device according to the present invention can adjust the brightness to facilitate the production of lighting devices that can save energy.

In addition, the administrator can preset various on / off times and their brightness levels, and the lamp can automatically control on / off and brightness according to this program. In addition, it is possible to automatically control the brightness according to the situation by detecting the ambient light.

In addition, it is possible to set and manage a plurality of lighting devices for each group, thereby increasing the management efficiency of a large number of lighting devices such as street lights.

In addition, it is possible to monitor the operation of the lighting device through the web camera installed in the lighting device and to receive the data in real time from the remote terminal, so that the remote control method can quickly cope with the malfunction of the lighting device such as a street lamp or the failure of the component. .
