DETAILED DESCRIPTION

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0040] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0041] In a first aspect of the present invention, a lighting device based on intelligent security is proposed, such as Figures 1 to 3 As shown, it is used to achieve range lighting of a target unit, including a light source 1 and an audio receiving module 2, and also includes a telescopic control mechanism 3 arranged on the top wall of the building, and a connecting disk 4 arranged on the light source 1, and the connecting disk 4 is movably connected to the output end of the telescopic control mechanism 3; two limit rods 5 are fixedly arranged above the connecting disk 4, and an annular sliding groove 41 is opened on the top wall of the connecting disk 4, and the bottom ends of the two limit rods 5 are both provided with a first ball head 51, and the bottom ends of the two limit rods 5 are movably connected to the sliding groove 41 through the first ball head 51; the angle formed between the two limit rods 5 and the axis of the connecting disk 4 is less than 180 degrees;

[0042] The center position between the two limit rods 5 is the midpoint, and the line segment formed between the connecting plate 4 and the midpoint is consistent with the moving path direction of the target unit; when the telescopic control mechanism 3 controls the connecting plate 4 to descend, the illumination range of the light source 1 will be toward the target unit;

[0043] The audio receiving module 2 is installed on the moving path of the target unit.

[0044] In this embodiment, the device is installed on the top wall of a building of a one-way channel, and the audio receiving modules 2 are arranged on the channel path. The audio receiving modules 2 are electrically connected to the controller. When the target unit passes through the channel, the sound generated by the target unit is captured by the audio receiving module 2, and the location of the sound source is determined by comparing the time difference or phase difference of the sound reaching each audio receiving module 2;

[0045] After determining that the sound source appears, the controller turns on the light source 1, and the light source 1 starts to emit light; and at the same time, the telescopic control mechanism 3 starts to work, and the telescopic control mechanism 3 drives the connecting plate 4 to move downward. During the process of the connecting plate 4 descending, due to the limiting effect of the two limit rods 5, the connecting plate 4 will be deflected, and the connecting plate 4 will drive the light source 1 to rotate with it, so that the illumination range of the light source 1 is toward the target unit;

[0046] Furthermore, the rotation angle of the light source 1 is determined according to the position of the sound source;

[0047] In the non-working state, the connection point between the connecting plate 4 and the telescopic control mechanism 3 and the connection points between the two limit rods 5 and the connecting plate 4 will form a three-point supported stable state.

[0048] As an implementation method, Figure 4 As shown, further:

[0049] The telescopic control mechanism 3 includes a guide tube 31 and a first connecting column 32; a limit plate 321 is provided at the top of the first connecting column 32, the limit plate 321 is located inside the guide tube 31 and is slidably connected thereto, and the bottom end of the first connecting column 32 is movably connected to the connecting disk 4; a limit ring plate 311 is provided at the bottom end of the guide tube 31, and the inner diameter of the limit ring plate 311 is smaller than the outer diameter of the limit plate 321;

[0050] An elastic element 33 is provided inside the guide tube 31 to push the limiting plate 321 upward, an electromagnet 34 is provided on the top wall of the limiting ring plate 311, and an iron material is provided on the bottom of the limiting plate.

[0051] In this embodiment, the telescopic control mechanism 3 starts to work, and the controller generates a magnetic field by energizing the electromagnet 34 and attracts the limit plate to descend. The limit plate descends and drives the first connecting column 32 to descend, and the first connecting column 32 drives the light source component 1 to descend with it through the connecting plate 4; during the descent of the connecting plate 4, due to the limiting effect of the two limit rods 5, the connecting plate 4 will be deflected, and the connecting plate 4 will drive the light source component 1 to rotate with it, so that the illumination range of the light source component 1 is toward the target unit;

[0052] The elastic element 33 is a spring but is not limited thereto. The elastic element 33 is used to keep the first connecting column 32 in a retracted state when the electromagnet 34 is not energized.

[0053] As an implementation method, Figure 4 As shown, further:

[0054] A second connecting column 36 is fixedly disposed on the top of the connecting plate 4 , a ball groove 35 is disposed on the bottom of the first connecting column 32 , and a second ball head 361 is disposed on the top of the second connecting column 36 , and the second ball head 361 is movably connected to the ball groove 35 .

[0055] As an implementation method, Figures 5 to 8 As shown, further:

[0056] The lighting device also includes a fixing plate 6 and an angle control mechanism 7 arranged at the bottom of the fixing plate 6. The fixing plate 6 is fixedly mounted on the top wall of the building. A fixing column 61 is arranged on the bottom wall of the fixing plate 6, and the fixing column 61 is fixedly connected to the guide tube 31.

[0057] The two limit rods 5 are transmission-connected to the angle control mechanism 7 , and the angle control mechanism 7 is used to drive the two limit rods 5 to rotate along the axis of the connecting disk 4 .

[0058] The angle control mechanism 7 includes a fixed ring frame 71 fixed to the bottom of the fixed plate 6, a rotating ring 72 is rotatably provided at the bottom end of the fixed ring frame 71, and the rotating ring 72 is rotatably connected to the guide tube 31, and the top ends of the two limit rods 5 are fixedly connected to the rotating ring 72;

[0059] The angle control mechanism 7 further includes a rotation driver 73 disposed outside the fixed ring frame 71 , and the rotation driver 73 is used for driving the rotating ring 72 to rotate.

[0060] The rotary driver 73 includes a servo motor 731 fixedly mounted on the outside of the fixed ring frame 71 . A gear 732 is disposed on the output shaft of the servo motor 731 . A gear ring 733 is fixedly sleeved on the rotating ring 72 , and the gear 732 meshes with the gear ring 733 .

[0061] A sleeve 721 is sleeved on the fixed column 61, and the sleeve 721 is fixedly connected to the top wall of the rotating ring 72, and a mirror surface 722 is provided on the outer wall of the sleeve 721;

[0062] At least one photoelectric sensor 74 is disposed on the fixed ring frame 71 , and the photoelectric sensor 74 faces the sleeve 721 .

[0063] In this embodiment, the number and order of the photoelectric sensors 74 are determined according to the installation point of the device. If the device is installed at the middle of a single channel, the photoelectric sensors 74 need to be installed symmetrically on the fixed ring frame 71 perpendicular to the path of the single channel. If the device is installed at the intersection of a cross channel, the photoelectric sensors 74 need to be installed on the fixed ring frame 71 corresponding to the distribution of the four channels.

[0064] When the target unit passes through the channel, the sound generated by the target unit is captured by the audio receiving module 2, and after the location of the sound source is determined; the rotation driver 73 starts to work, and the servo motor 731 drives the gear 732 to rotate. Since the gear 732 is engaged with the ring gear 733, when the gear 732 rotates, it will drive the ring gear 733 to rotate with it, and the ring gear 733 drives the rotating ring 72 to rotate; since the outer wall of the sleeve 721 installed on the rotating ring 72 is provided with a mirror 722, whether the photoelectric sensor 74 corresponding to the sound source location receives the reflection signal of the mirror 722 on the sleeve 721, it is judged whether the next rotation direction of the light source 1 is consistent with the sound direction.

[0065] The present invention proposes a lighting method based on smart security, and the lighting method comprises the following steps:

[0066] Step 1: When the target unit passes through the channel, the sound generated by the target unit is captured by the audio receiving module 2, and the sound source position is determined by comparing the time difference or phase difference when the sound reaches each audio receiving module 2;

[0067] Step 2: After confirming that the sound source appears, the controller turns on the light source 1, and the light source 1 starts to emit light.

[0068] Step 3: The driver drives the rotating ring 72 to rotate;

[0069] Step 4: Determine whether the direction of the next rotation of the light source 1 is consistent with the direction of the sound by checking whether the photoelectric sensor 74 corresponding to the sound source position receives the reflection signal of the mirror 722 on the sleeve 721;

[0070] Step 5: After the direction is determined, the electromagnet 34 is energized to generate a magnetic field and adsorb the limit plate to descend. The limit plate descends and drives the first connecting column 32 to descend. The first connecting column 32 drives the light source 1 to descend with it through the connecting plate 4.

[0071] Step 6: During the descent of the connection plate 4, due to the limiting effect of the two limit rods 5, the connection plate 4 will deflect, and the connection plate 4 will drive the light source 1 to rotate with it, so that the illumination range of the light source 1 faces the target unit;

[0072] Step 7: The rotation angle of the light source 1 is further determined according to the position of the sound source.
