Other features and effects of the present invention will be clearly presented in the embodiments with reference to the drawings, wherein: FIG. 1 is a flowchart illustrating an embodiment of the lighting control method of the present invention; FIG. 2 is a schematic diagram illustrating the A planar area and a plurality of candidate optimal paths of an embodiment; and FIG. 3 is a schematic diagram illustrating the planar area and one of the candidate paths of the embodiment. An aspect of multiple lighting ranges that choose the best path.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated by the same reference numerals.

Referring to FIG. 1 and FIG. 2 , an embodiment of the lighting control method of the present invention is applicable to a lighting control system and a flat area. The lighting control system includes a control unit and a plurality of lighting units. The control unit is, for example, a microcontroller and a touch screen. Each lighting unit corresponds to a lighting range, and each lighting range is located at A1 in FIG. 2 . ~A20 shown. The flat area is, for example, an indoor office. But not limited to this. It should be noted that, for the sake of simplicity in the drawings, the lighting units are not shown in FIGS. 2 to 3 , but only the corresponding lighting ranges are shown, and the control unit is also not shown.

The lighting control method includes steps S1 to S6.

In step S1, an integral value corresponding to each lighting unit is pre-stored by the control unit, and the integral value is related to the energy consumption amount of the corresponding lighting unit when it is turned on. In more detail, each of the integral values is related to a power consumption of the corresponding lighting unit, and the power consumption is related to the type and quantity of electric lamps of the corresponding lighting unit. In this embodiment, the power consumption is classified into a plurality of sections, and the integral value corresponding to the power consumption in each section is the same. For example, four of the lighting units respectively correspond to 5 LED lights and the power consumption is 1kwh, 5 LED lights and the power consumption 1kwh, 8 LED lights and 2 halogen lamps and the power consumption is 2kwh, and 8 LED lights and the power consumption is 1.6kwh; the integral value of the power consumption is 0, and the power consumption is between 0 The integral value between 1kwh is 0.1, the integral value between 1 and 1.5kwh is 0.2, the integral value between 1.5 and 2kwh is 0.3, the power consumption is medium The integral value between 2 and 2.5kwh is 0.4.

In step S2, the control unit pre-stores a plurality of aisle positions corresponding to the equal aisle in the plane area, and a plurality of illumination range positions corresponding to the equal illumination area in the plane area in advance.

In step S3, one of the illumination areas is selected as a target area by the control unit. For example, an employee of a company goes to work in the indoor office on a holiday, and selects the target area where his seat is located by the touch screen of the control unit near an entrance of the indoor office.

In step S4, the control unit calculates a plurality of candidate maximums from the starting point to the target area according to the position of a starting point in the plane area, the lighting range position of the target area, and the aisle positions. optimal paths, each of the candidate optimal paths includes a portion of the walkways. The starting point is, for example, the aforementioned entrance of the planar area. In this embodiment, the candidate optimal paths are the top N with the shortest relative distance among a plurality of possible paths from the starting point to the target area, where N is a complex number. Referring to FIG. 2 again, for example, N is equal to 5, the target area is the lighting range position A3, the starting point is the circle position in the figure, and the five candidate optimal paths are the walkways respectively Positions P1+P2+P6+P7, P3+P4+P5+P6+P7, P8+P9+P10+P11+P12, P8+P14+P16+P11+P12, P13+P15+P16+P11+P12.

In step S5, the aisle positions of the aisles, the lighting range positions capable of illuminating the aisle positions, and the corresponding lighting range positions of the aisles according to one of the candidate optimal paths, and the corresponding the integral values of the lighting area positions at the aisle positions, determine the lighting areas that are at least required to illuminate the aisle positions, and calculate a total integral value of the lighting areas that are at least required to illuminate the aisle positions .

For example, referring to FIG. 3 again, one of the illumination range positions capable of illuminating one of the candidate best paths (ie, the aisle positions P8+P14+P16+P11+P12) is A18, A17, A6, and Another such illumination range position that can be illuminated is A18, A8, A6, A4. Then, the two integral total values corresponding to the former and the latter are, for example, 1.1 and 1.5, respectively. Therefore, the former is the illumination range that needs to illuminate the aisle positions at least. For other candidate optimal paths, the corresponding integral total values are calculated in a similar manner.

In step S6, the control unit determines that the candidate optimal path corresponding to the smallest of the total integral values is an optimal path. Furthermore, when the smallest one of the total integral values is a plurality, the control unit selects the corresponding candidate optimal path with the shortest relative distance as the optimal path. That is to say, when the total points of the different candidate optimal paths are the same, that is, when the power consumption is the same, the shorter path is preferentially selected. When the path lengths of the two are exactly the same, then Choose one of them at random.

The control unit controls the lighting units corresponding to the lighting ranges of the aisle positions that are least required to illuminate the optimal path to be turned on. In this embodiment, the control unit sequentially controls the lighting units corresponding to the optimal path from the starting point to the target area to be turned on. In other embodiments, the control unit sequentially controls the lighting units corresponding to the optimal path from the starting point to the target area to turn on, and after turning on the next lighting unit or at the same time, Turn off the previous lighting unit. But not limited to this.

In addition, it should be specially added that: in this embodiment, the lighting range positions shown in FIGS. 2 to 3 do not include the aisle positions, which are in a simple and clear schematic form. In fact, only the lighting range positions pre-stored by the control unit can indicate which lighting range positions include which corridor positions. And the control unit executes step S5 exactly according to the pre-stored correct positional relationship.

To sum up, the lighting control method can first determine the candidate optimal paths, and then determine the integral total values corresponding to the candidate optimal paths according to the integral value of each lighting unit, so as to determine The lighting ranges of the aisle positions of the optimal path should be turned on to achieve the best result of safety and energy saving, so the object of the present invention can be achieved indeed.

However, the above are only examples of the present invention, which should not limit the scope of the present invention. Simple equivalent changes and modifications made to the contents still fall within the scope covered by the patent of the present invention.
