Therefore, a teaching auxiliary lighting device that can flexibly adjust the light is needed to meet the needs of different teaching scenarios. In order to solve the problems of blackboard reflection and clarity, the prior art generally sets a blackboard lamp in front of the blackboard. The existing blackboard lamp generally has an angle adjustment function. For example, the patent with announcement number CN114872479B discloses an adjustable multifunctional blackboard lamp, which realizes the angle adjustment of the blackboard lighting lamp and the shading plate.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] like Figure 1 As shown, a teaching auxiliary lighting device includes a control terminal 1, an indoor lighting mechanism 2 and a blackboard lighting mechanism 3.

[0044] The indoor lighting mechanism 2 is mainly used for lighting the students' positions in the classroom. The indoor lighting mechanism 2 includes a number of classroom lighting lamps 21, which are distributed in a matrix on the top of the classroom. A human sensor 22 is installed on the classroom lighting lamps 21. The classroom lighting lamps 21 and the human sensor 22 are both electrically connected to the control terminal 1. The lighting area surrounded by all classroom lighting lamps 21 that detect human activities within the lighting range, all classroom lighting lamps 21 in the lighting area are lit. A classroom lighting control switch 23 is set in the classroom to control the turning on and off of the classroom lighting lamps 21. The priority of the classroom lighting control switch 23 is greater than the control of the control terminal 1. When the classroom lighting control switch 23 is in the on state, the corresponding classroom lighting lamp 21 can be turned on and off through the detection data of the human sensor 22.

[0045] like Figure 2 As shown, the blackboard lighting mechanism 3 is installed on the top of the classroom through the sliding mechanism 4, and the blackboard lighting mechanism 3 is connected to the blackboard through the following mechanism 5, so that when the blackboard is pulled during the teaching process, the blackboard lighting mechanism 3 also moves with it to ensure the clarity of the blackboard. It should be noted that: in order to clearly show the following mechanism 5 Figure 2 Only one blackboard lighting mechanism 3 is provided.

[0046] The blackboard lighting mechanism 3 includes a blackboard lamp 31. The blackboard lamp 31 is installed just above the blackboard so that light can be irradiated vertically downward onto the blackboard, ensuring uniform illumination on the blackboard surface so that students can clearly see the content on the blackboard. At the same time, this installation method can effectively reduce shadows and prevent the teacher from blocking the light with his body while writing and forming shadows on the blackboard, which affects students' viewing. A connecting plate 32 is installed on the upper side of the blackboard lamp 31. A T-shaped sliding portion 33 is provided on the top of the connecting plate 32. Rollers 34 are installed at both ends of the T-shaped sliding portion 33. The lamp tube in the blackboard lamp 31 is connected to an angle adjustment motor 35. Both the blackboard lamp 31 and the angle adjustment motor 35 are electrically connected to the control terminal 1 for adjusting the switch state and angle of the blackboard lamp 31. The sliding mechanism 4 includes a slide rail 41. The T-shaped sliding portion 33 is provided in the slide rail 41. Limiting blocks 42 are provided at both ends of the slide rail 41. A positioning component 43 is provided on the slide rail 41, such as Figure 3 As shown, the positioning assembly 43 includes a positioning plate 431 disposed inside the slide rail 41, one side of the positioning plate 431 is a wavy surface disposed opposite to the roller 34, the other side of the positioning plate 431 is connected to a guide rod 432, the guide rod 432 is connected to a linkage plate 433, both ends of the linkage plate 433 are connected to positioning electric push rods 434, and the positioning electric push rods 434 are installed on the slide rail 41. The positioning electric push rod 434 is electrically connected to the control terminal 1. When the blackboard needs to be positioned, the positioning electric push rod 434 is started to change from an extended state to a retracted state, the guide rod 432 pushes the positioning plate 431 inward, and the wavy surface of the positioning plate 431 squeezes the roller 34, so that the position of the blackboard lamp 31 is fixed.

[0047] The following mechanism 5 includes a mounting frame 51 fixed on a wall or a blackboard frame, and the blackboard includes a first blackboard 7 and a second blackboard 8 slidably arranged on the blackboard frame. A first double-sided rack 52 and a second double-sided rack 53 are slidably arranged on the mounting frame 51 (the sliding installation of the double-sided rack and the mounting frame 51 is achieved through dovetail grooves and sliding bars, and guide rails or other methods can be set according to actual conditions to achieve sliding connection). The first double-sided rack 52 and the second double-sided rack 53 are arranged opposite to each other up and down, so that the first double-sided rack 52 and the second double-sided rack 53 will not interfere with each other. The first bilateral rack 52 is meshed with a first internal transmission gear 54 and a first external transmission gear 55 on both sides, the first internal transmission gear 54 is meshed with a first internal rack 56 installed on the first blackboard 7, the first external transmission gear 55 is meshed with a first external rack 57 installed on the blackboard lamp 31, and the first internal transmission gear 54 and the first external transmission gear 55 are both installed on the mounting frame 51; the second bilateral rack 53 is meshed with a second internal transmission gear 58 and a second external transmission gear 59 on both sides, the second internal transmission gear 58 is meshed with a second internal rack 510 installed on the second blackboard 8, the second external transmission gear 59 is meshed with a second external rack 511 installed on the blackboard lamp 31, and the second internal transmission gear 58 and the second external transmission gear 59 are both installed on the mounting frame 51, and the second internal rack 510 and the second external rack 511 are both provided with an extension plate 512 to compensate for the height difference between the first bilateral rack 52 and the second bilateral rack 53.

[0048] like Figure 4 As shown, the uniformity detection mechanism 6 includes a delivery motor 61 installed on the housing of the blackboard lamp 31, the delivery motor 61 is connected to a rotating shaft 62 installed on the housing of the blackboard lamp 31, a layout net 63 is arranged on the rotating shaft 62, a plurality of illuminometers 64 are arranged on the layout net 63, and a vertical plate 65 is arranged at the bottom of the layout net 63; at least two positioning airbag rolls 66 arranged in parallel are arranged on the vertical plate 65, and the positioning airbag roll 66 is connected to an air pump 67 in the middle of the vertical plate 65, and the air pump 67, the delivery motor 61 and the illuminometer 64 are all electrically connected to the control terminal 1. The positioning airbag roll 66 is in a curled state in a natural state and will not be entangled on the layout net 63. In the inflated state, the positioning airbag roll 66 bulges and straightens under the action of air pressure, so that it has a certain supporting force, so that the layout net 63 remains parallel to the blackboard, which is convenient for the subsequent illuminometer 64 to collect the illuminance value.

[0049] The specific process is as follows:

[0050] When conducting uniformity detection, start the delivery motor 61 to rotate forward to lower the laying net 63. The laying net 63 is set vertically to the ground under the action of the vertical plate 65. Start the air pump 67 to inflate the positioning airbag roll 66. The positioning airbag roll 66 extends outward and straightens under the action of air pressure and contacts the blackboard or the wall, so that the laying net 63 is set parallel to the blackboard. Start the angle adjustment motor 35 to adjust the illumination angle of the blackboard lamp 31 at a set interval, and collect the illumination of each test point through the illuminance meter 64. After the detection is completed, start the delivery motor 61 to reverse and retract the laying net 63. At the same time, start the air pump 67 to evacuate the positioning airbag roll 66, calculate the illumination uniformity of each illumination angle, and control the angle adjustment motor 35 to make the blackboard lamp 31 at the illumination angle corresponding to the maximum uniformity.

[0051] The electronic whiteboard 9 is electrically connected to the control terminal 1 . When the electronic whiteboard 9 is in use, the control terminal 1 controls the blackboard lamp 31 to be turned off to prevent the blackboard lamp 31 from affecting the use of the electronic whiteboard 9 .

[0052] A pressure sensor is provided on the back of the blackboard, and the pressure sensor is electrically connected to the control terminal 1. When the pressure value of the pressure sensor is greater than the set value, it is determined that the blackboard is being used. When the blackboard is in use, the control terminal 1 controls the blackboard lamp 31 to turn on.

[0053] At the same time, the control terminal 1 is equipped with a control remote control 10, which is used to control the blackboard lamp 31. The control remote control 10 is provided with an on key, an off key, a hold key, an adjustable key and a positioning key, so as to facilitate the self-selected mode control of the blackboard lamp 31.

[0054] A method for using the above teaching auxiliary lighting device, the specific steps are as follows:

[0055] Step S1: Start the uniformity detection mechanism 6 to adjust the irradiation angle of the blackboard lamp 31 .

[0056] Start the delivery motor 61 to rotate forward to put down the laying net 63, and start the air pump 67 to inflate the positioning airbag roll 66, so that the laying net 63 is set parallel to the blackboard, start the angle adjustment motor 35 to adjust the irradiation angle of the blackboard lamp 31 at a set interval, and collect the illuminance of each test point through the illuminance meter 64. After the detection is completed, start the delivery motor 61 to reverse and retract the laying net 63, and start the air pump 67 to evacuate the positioning airbag roll 66, and calculate the irradiation uniformity of each irradiation angle. The calculation formula is as follows:

[0057]

[0058] Among them, S α is the uniformity when the illumination angle is α, n is the number of illuminance meters, is the illuminance value of the ith illuminance meter when the irradiation angle is α, is the average value of n illuminance meters when the illumination angle is α.

[0059] The angle adjustment motor 35 is controlled so that the blackboard lamp 31 is at an illumination angle corresponding to the maximum uniformity.

[0060] Step S2: Control the blackboard lamp 31 according to the operation mode of the remote control 10.

[0061] The operation modes include holding mode, follow-up mode and positioning mode.

[0062] In the holding mode and the positioning mode, the blackboard lamp 31 is regulated by controlling the on and off keys of the remote control 10; in the positioning mode, the positioning electric push rod 434 is in a retracted state, and the blackboard lamp 31 and the blackboard are fixed in position.

[0063] In the adjustment mode, the blackboard lamp 31 is adjusted according to the usage of the pressure sensor and the electronic whiteboard 9 .

[0064] Step S3: According to the actual teaching activities, the classroom lighting control switch 23 and the control terminal 1 are used to control the on and off of each classroom lighting 21; the classroom lighting control switch 23 has a higher priority than the control terminal 1. When the classroom lighting control switch 23 is on, the control terminal 1 controls the on and off of each classroom lighting 21 according to the actual student location. Figure 1 As shown, in Figure 1 The portion surrounded by the dotted line in the figure is the lighting area, which is suitable for a larger classroom but a small class. The classroom lighting lamp 21 is turned on according to the actual seating situation to achieve energy-saving effect.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.

The calculation formula is as follows: Among them, S α is the uniformity when the illumination angle is α, n is the number of illuminance meters, is the illuminance value of the ith illuminance meter when the irradiation angle is α, is the average value of n illuminometers when the illumination angle is α; By controlling the angle adjustment motor, the blackboard lamp is at the irradiation angle corresponding to the maximum uniformity; Step S2: Control the blackboard lamp according to the operation mode of the remote control; The operation modes include holding mode, adjustment mode and positioning mode; In the holding mode and positioning mode, the blackboard lamp is regulated according to the on and off keys of the remote control; in the positioning mode, the positioning electric push rod is in a retracted state, and the blackboard lamp and the blackboard are fixed in position; In the adjustment mode, the blackboard light is adjusted according to the pressure sensor and the usage of the electronic whiteboard; Step S3: Control the turning on and off of each classroom light through the classroom lighting control switch and the control terminal according to actual teaching activities; the priority of the classroom lighting control switch is greater than the control terminal control. When the classroom lighting control switch is in the on state, the control terminal controls the turning on and off of each classroom light according to the actual student location.
