In order to better understand the above and other aspects of the present invention, the following detailed description of the embodiments and the accompanying drawings

Please refer to FIGS. 1A and 1B. FIG. 1A is a schematic diagram of a lighting control system 100 according to an embodiment of the present invention, and FIG. 1B is a bottom view of the lighting control system 100 of FIG. 1A.

The lighting control system 100 includes a lever 110, a lampshade 115, a plurality of first light source modules 120, a light sensor 130, a moving mechanism 135, and a controller 140.

The rod 110 includes a first end 111 and a second end 112. The rod 110 is configured or interposed at a first end 111 at a field C1. The shade 115 is disposed at the second end 112 of the rod 110. A plurality of first light source modules 120 are disposed in the light cover 115 to illuminate the field C1. As shown in FIG. 1B, the plurality of first light source modules 120 may be arranged in an array, and each of the first light source modules 120 may be irradiated to different areas of the field C1 after appropriately adjusting the illumination angle. As shown, the number of first light source modules 120 is twelve, so that 12 different illumination areas can be illuminated. However, embodiments of the present invention do not limit the number of first light source modules 120, which may be more than 12, or less than 12. In addition, each of the first light source modules 120 can include a circuit board (not shown) and at least one light emitting die (not shown), wherein the circuit board is disposed on the lamp cover 115, and the light emitting die is disposed on the circuit board. Alternatively, the plurality of first light source modules 120 may be disposed together on a circuit board (not shown). The luminescent crystal is, for example, a light-emitting diode or any other illuminating element capable of emitting light.

As shown in Fig. 1A, a rod member 110, a lampshade 115 and a plurality of first light source modules 120 may constitute an illumination lamp holder 110'. The lighting control system 100 is exemplified by two lighting fixtures 110', but only one or more than two. The illuminating light fixture 110' may be disposed at the edge of the field C1, although the invention is not limited thereto. The venue C1 is, for example, a sports field, a store, a shopping mall, a banquet hall, a stage, and the like, which require various lighting. The embodiment of the invention is described by taking a sports field as an example.

The first light source module 120 of FIG. 1A shows only four of them, such as the first light source modules 121-124. The first light source modules 121 to 124 exemplify the features of the first light source module according to the embodiment of the present invention, and the remaining unillustrated first light source modules have similar or identical features.

The first light source modules 121-124 respectively emit first light rays L1 to L4 having different light-emitting frequencies, and each light-emitting frequency has a corresponding identification code, and the first light rays L1 to L4 are respectively irradiated to a plurality of different illumination regions. For example, it is R1~R4. The illumination areas R1 to R4 are, for example, the ground areas of the site C1, but the embodiments of the present invention are not limited thereto. The photo sensor 130 is configured to sense the first rays L1 L L4. For example, the light sensor 130 can sense the first light L1 emitted by the first light source module 121 and emit a detection signal S1, wherein the detection signal S1 includes the identification code and the light emitting characteristic of the first light L1, and emits light. The characteristics are, for example, light intensity, light color temperature, and/or color rendering property. The controller 140 is configured to adjust the illuminating characteristic of the first light ray L1 of the first light source module 121 according to the detecting signal S1 emitted by the photo sensor 130. In this manner, the lighting control system 100 can adjust the lighting characteristics of the first light source modules 121-124 according to the actual lighting conditions of the site R1.

In addition, the first light sources 121 to 124 emit different first light rays. For example, the first light source modules 121-124 can adopt different pulse width modulation (PWM) frequency illumination, wherein each illumination frequency has a corresponding identification code, and the detection signal S1 sent by the photo sensor 130 The identification code corresponding to the sensed first light rays L1 L L4 may be included. Because the illumination frequencies of the first light source modules 121-124 are different, the controller 140 can identify the first light source module corresponding to the illumination frequency according to the identification code of the detection signal S1 sent from the photo sensor 130. 120. Then, the illuminating characteristics of the first light source module 120 are separately adjusted accordingly. In addition, the light-emitting frequency of the first light rays L1 to L4 is, for example, greater than 20 KHz, so that the light-emitting frequency can be reduced or even prevented from being disturbed by a camera or other optical products. In addition, when the field C1 is illuminated by the daylight LS (shown in FIG. 1A), since the daylight LS does not have the specific light-emitting frequency of the first light source module 120, the detection signal S1 is not affected by the daylight LS.

In addition, the power of the first light source module 120 is, for example, 200 watts or more. However, the embodiment of the present invention does not limit the power range of the first light source module 120, which may be determined by the requirements of the site C1.

The two illumination regions illuminated by the two light emitted by the adjacent two first light source modules 120 may overlap each other. For example, as shown in FIG. 1A, the two illumination regions R1 and R2 illuminated by the first light rays L1 and L2 emitted by the adjacent two first light source modules 121 and 122 are partially overlapped, so that the illuminance of the overlap region can be increased. The illuminance distribution of the two illumination areas is more uniform. In addition, the photo sensor 130 can detect the proportion of the first light L1, L2 in the overlapping area, and send the detection signal S1 to the controller 140 to adjust the proportion of the first light L1, L2 in the overlapping area, respectively. . In this embodiment, the illumination angles of the first light source modules 121-124 are fixed to the illumination area. In the first light source module 121, the illumination angle of the first light source module 121 during the illumination process It is not adjustable with the illumination area R1.

In another embodiment, during the illumination process, the controller 140 can control an adjustment mechanism (not shown) to adjust the illumination angles of the first light source modules 121-124 to change the first light source modules 121-124. An illumination area of light L1~L4. In the first light source module 121, during the illumination process, the controller 140 can control the adjustment mechanism to adjust the illumination angle A1 of the first light source module 121. The illumination angle A1 is, for example, the angle of the optical axis of the first light ray L1 of the first light source module 121 with respect to the rod 110 or with respect to a reference axis. In addition, the optical axis or the illumination angle range of the first light source modules 121-124 avoids covering the horizontal direction to reduce light damage and reduce the light loss of the illumination field C1. In an embodiment, the maximum illumination angle Am of the first light source modules 121-124 is, for example, less than degree. The adjustment mechanism is connected to the first light source modules 121-124. The adjustment mechanism is, for example, a link mechanism, a cam mechanism, or any other mechanism capable of driving the first light source modules 121-124 to rotate and/or move.

In an embodiment, the light sensor 130 can be disposed on the moving mechanism 135. The moving mechanism 135 can move between the illumination regions R1 R R4 to drive the photo sensor 130 to sense the first rays L1 L L4 that are irradiated to the illumination regions R1 R R4 . The moving mechanism 135 can scan the entire field C1, i.e., scan along the XY plane, for example, scanning a plurality of illumination areas R1 R R4 of the two illumination stand 110' shown in Fig. 1A.

The photo sensor 130 sends a detection signal S1 to the controller 140 by using a wireless communication technology. For example, the photo sensor 130 sends a detection signal S1 to the controller 140 through a wireless communication device (not shown), wherein the wireless communicator can be integrated into the photo sensor 130. In another embodiment, the photo sensor 130 and the controller 140 can be connected through a wire, and the photo sensor 130 sends a detection signal S1 to the controller 140 through the wire. Similarly, the controller 140 can control the first light source modules 121-124 through a wireless communication device (not shown). In another embodiment, the controller 140 and the first light source modules 121-124 can be electrically connected to each other, so that the controller 140 controls the first light source modules 121-124 through the wires.

In this manner, the controller 140 can adjust the illumination of the first light source module 120 according to the field illumination information of the detection signal S1 sent from the light sensor 130, so that the illumination of the site C1 conforms to a set illumination. For example, the illumination control system 100 can automatically adjust the illumination of the at least one first light source module 120 to provide a uniform illumination distribution of the site C1. The illuminance of the foregoing is, for example, a system-defined value, or an input value that is input by a user through a user interface (not shown).
