Hereinafter, a control method of a lighting apparatus according to the present invention will be described with reference to the accompanying drawings.

2 is a flowchart of an example for explaining a control method of a lighting apparatus according to the present invention.

As shown in FIG. 2, when the power switch (not shown) for driving the lighting apparatus of the present invention is turned on (S101), the controller 117 controls the calendar (the lunar and lunar calendar) stored in the memory 113. With reference to this, current date and time information is detected (S102). The detected information may be used to determine the current season, 24 seasons, anniversaries, and the like, to determine day / night of the day.

Accordingly, assuming that the current time corresponds to a night time, the current day is a weekday without a special event, and the current season is spring, the controller 117 selects a specific color according to a program according to a preset season. : Yellow, light green) to drive the lighting unit 120 (S103 ~ S106). If it is not at night or late at night, the lighting is turned off (S105).

In this case, the time corresponding to the night may vary depending on the season, and may vary according to the weather conditions of the day. For example, it is typically set to drive the lighting unit at 6 pm at night, but the weather may be poor and darken more quickly. Therefore, the controller 117 checks the sensor unit 111 at regular intervals to detect the ambient illuminance of the place to be illuminated, and when the ambient illuminance is dark below the reference illuminance, the illumination unit 120 even though it is not a night time. ) Can be driven. In addition, even at night, the driving method of the lighting unit 120 may be different in the night time zone.

In addition, in the present invention, when the controller 117 is a weekday without a specific event or event (S107), by continuously measuring the illumination at night (S109), depending on whether there is a moon light or a street lamp, depending on the illumination of the place to be illuminated If there is a difference, the brightness of the lighting unit 120 may be made brighter or darker (S110 ˜ S112).

For example, when driving for the purpose of illuminating a dark place on a weekday, when the ambient light is low, the driver is driven brighter (S111). Can be driven (S112). If there is a specific event or event (S108), in order to produce a special effect according to the event (for example, an event schedule), the maximum and minimum brightness may be dynamically controlled regardless of the ambient illumination ( S108). At this time, in the above embodiment, only the method for controlling the brightness is described, but it will be apparent that the control over the color is also possible.

As described above, the lighting device 100 of the present invention varies the color, driving time, and brightness of the lighting unit 120 according to the installed place, weather conditions, time zone (year, month, day, time), and event of the place. Can be controlled.

In addition, according to the purpose or purpose of the place where the lighting device is installed, the driving pattern (for example, adjusting the flicker of the lamp for each function or the lamp for each color) and each function lamp can be driven in combination as appropriate. It will be described with reference to.

However, since the driving of the lighting according to time has already been described above, the description thereof will be omitted and the lighting control method in various other practical situations will be described in more detail.

Referring to Figure 3, when installing the lighting apparatus of the present invention, the user determines the installation place or purpose of the lighting device (S201), and sets the lighting mode according to the determined place or purpose (S202).

The lighting mode is a basic mode that is normally driven according to the place or purpose of the lighting device is installed, may be set through the main computer 200, or may be set through the lighting device serving as a host. The lighting mode may be set in plural according to a weather condition or time, and may be automatically changed by determining whether the controller 117 meets a specified condition through the sensor unit 111.

According to the illumination mode initially set as described above, the controller 117 drives the illumination with the number, color, function, and pattern of illumination (S203).

For example, in the same park, when installed for a walkway block of a quiet walkway, the lighting unit can be driven with a color or a pattern that can provide peace of mind or a healing effect. It can drive special function lamps such as colored lights, patterns, or infrared lamps that can activate metabolism.

In addition, when installing a plurality of lighting devices 100 of the present invention in a special purpose park (for example, a constellation park), it is also possible to control each lighting device to illuminate the constellation shape, an indicator for indicating the special event location It can also be illuminated for use as an indicator. In addition, the lighting can be controlled by different shapes according to distinctive streets and ecological rivers, such as apartment facades, bridges, walkways, and landscaping.

At this time, the controller 117 continuously detects the weather state or time around the lighting apparatus even while driving the lighting apparatus as described above (S204), and determines whether the weather state has changed or a specified specific time ( S205). If the specific weather does not occur or the predetermined time is not reached, the lighting is driven according to the existing lighting mode.

However, when the weather condition or a predetermined time is reached, the purpose of the lighting is also changed according to the detected weather condition (or time) (S206), and the controller 117 sets a new lighting mode according to the changed purpose. (S207).

For example, when the weather conditions are suddenly changed to rain or snow, it is changed from the basic lighting mode to the safety display lighting mode (or mood lighting mode).

Of course, the lighting mode changed according to the weather condition as described above may also change depending on the place where the lighting device is installed. That is, the lighting device installed in the park mainly visited by lovers can be changed to the mood lighting mode that can make the effect of increasing the emotional index of lovers in the rain or snow. However, lighting devices installed on roads, bridges, structures, etc. may increase the alertness and increase the brightness to improve safety, and may drive only a color that can be identified from a distance, such as red, yellow, and orange, in a specific pattern (blinking).

Each illumination mode is not necessarily fixed in one pattern, and may be arbitrarily changed with reference to various known data such as color therapy.

As described above, the lighting apparatus 100 of the present invention sets various lighting modes according to the installed place or purpose, and controls the lighting mode to be automatically changed in response to the situation according to the weather state or time.

At this time, by applying the fuzzy theory to the controller 117 of each lighting device 100, it can be made to drive more smoothly.

On the other hand, it can be driven to obtain a special molding effect by connecting a plurality of the lighting device, this will be described with reference to the accompanying FIG.

Therefore, a plurality of lighting devices can be linked to generate special molding or effects by lighting, to monitor the status of each lighting device, or to update a program or data. However, since the configuration of the communication program and the coding method thereof are outside the gist of the present invention, description thereof will be omitted and only the application method thereof will be described.

When the plurality of lighting apparatuses are to be linked and controlled, the lighting apparatuses may be distributed in various places or concentrated in one place depending on a place to be installed or a desired lighting effect. In addition, as shown in FIG. 4A, the main computer 200 may directly transmit sequential data according to time to each lighting device. In order to reduce the load on the main computer as shown in FIG. It is possible to set the rank in order to receive data transmitted from the main computer from the upper lighting device according to the ranking, and to automatically transmit to the lower lighting device.
