Referring to FIG. 2, FIG. 3 and FIG. 4, an embodiment of the light-seeking and positioning device 2 of the present invention is suitable for a bright light 21. The bright light 21 includes a lamp post body 211 that can be driven to rotate around an axis L1, and several lamp row groups 212 arranged around the lamp post body 211 . Each lamp row group 212 corresponds to a lamp row number, and has a plurality of lamp boxes 213 arranged up and down. Each light box 213 corresponds to a light box number. The light-seeking and positioning device 2 includes a base unit 3 , a driving unit 4 , an encoding unit 5 , an electromagnet 6 , and a control unit 7 .

The base unit 3 includes a base body 31 for the lamp post body 211 to be disposed above, and an index 32 disposed on the outer surface of the base body 31 .

The drive unit 4 is disposed in the base body 31 and includes a motor 41 electrically connected to the control unit 7 , a transmission gear 42 connected to the motor 41 and driven to rotate by the motor 41 , a transmission gear 42 engaged with the transmission The driven gear 43 of the gear 42 and a link 44 along the axis L1 connecting the driven gear 43 and the lamp post body 211 . In this embodiment, the linkage 44 is a shaft.

Referring to FIGS. 3 to 6 , the encoding unit 5 is disposed in the base body 31 , and includes a disk 51 connected to the link 44 and rotated around the axis L1 by the link 44 , and a plurality of disks 51 surrounding the link 44 . The axis L1 is formed on the disc 51 at equal angular intervals and can transmit light along an up-down direction Z parallel to the axis L1. The positioning light-transmitting area 53 between the two adjacent ones of the 52 and can transmit light along the up-down direction Z, and electrically connected to the control unit 7 and located on the two opposite sides of the disc 51 in the up-down direction Z and corresponding to A light source 54 and a light sensor 55 are located in the equally spaced light-transmitting area 52 and the positioning light-transmitting area 53 . The number of the equally spaced light-transmitting areas 52 corresponds to the number of the lamp row groups 212 respectively, so the lamp row numbers correspond to the equally spaced light-transmitting areas 52 respectively. The light source 54 can be controlled by the control unit 7 to emit light in the direction of the light sensor 55 , and the light sensor 55 receives the light passing through each interval light-transmitting area 52 and generates a corresponding interval sensing signal 551 , and the light sensor 55 can also receive the light passing through the positioning light-transmitting area 53 and generate a positioning sensing signal 552 . In this embodiment, the disc 51 is made of metal material.

The electromagnet 6 is disposed in the base body 31 adjacent to the side of the disc 51 and is electrically connected to the control unit 7 . The control unit 7 can control the electromagnet 6 to be energized to generate a magnetic force to make the rotating disc 51 51 is stopped by the magnetic force.

The control unit 7 can control the operation of the motor 41 to drive the transmission gear 42 to rotate. The transmission gear 42 drives the driven gear 43 to rotate and links the linkage 44 , the disc 51 , and the lamp post body 211 around the axis. L1 turns. When the disk 51 is rotated in conjunction, the light sensor 55 receives the light passing through the equally spaced light-transmitting regions 52 to generate the equally spaced sensing signals 551 corresponding to the equally spaced light-transmitting regions 52 at intervals to the The control unit 7 receives the light passing through the positioning light-transmitting area 53 to generate the positioning sensing signal 552 corresponding to the positioning light-transmitting area 53 and between the corresponding two interval sensing signals 551 to the control unit 7 .

Referring to FIG. 5 and FIG. 6 , since the equally spaced light-transmitting regions 52 are formed on the disk 51 at equal angular intervals around the axis L1 , any two adjacent spaced sensing signals 551 are sensed at equal intervals. The time interval between the signals 551 is a fixed value, and because the positioning sensing signal 552 is between the corresponding two interval sensing signals 551, the positioning sensing signal 552 and the preceding interval sensing signal 551 The time interval between is less than the fixed value, and the control unit 7 determines that the positioning sensing signal 552 has been received accordingly.

The control unit 7 is used for the lighter to input the lamp box number corresponding to the lamp box 213 to be found, and obtain the lamp corresponding to the lamp row group 212 from the lamp row group 212 where the lamp box number is located row number, and calculates a predetermined number according to the lamp row number, where the predetermined number is the number of the equally spaced sensing signals 551 corresponding to the lamp row number after the positioning sensing signal 552 . The control unit 7 controls the motor 41 to rotate to drive the disk 51 to rotate, and after judging that the positioning sensing signal 552 is received and before the number of the equally spaced sensing signals 551 is the same as the predetermined number, controls the The motor 41 stops running, because the motor 41 still has inertia after the power is turned off and will not stop rotating immediately, so that the disk 51 is still connected and continues to rotate. When the predetermined number is the same, the electromagnet 6 is controlled to be energized to stop the rotation of the disc 51, so that the lamp row group 212 where the lamp box 213 that the lighter wants to find is located is stopped at the indicator 32, and The light box 213 flashes to remind the lighting person.

A detailed example is as follows, when the number of the lamp row groups 212 is twenty-four in total, the corresponding lamp row numbers are No. 1 to No. 24, and the number of the light-transmitting areas 52 at equal intervals is also twenty-four , if the disc 51 is rotated clockwise, the number of the lamp row corresponding to the interval light-transmitting area 52 adjacent to the right side of the positioning light-transmitting area 53 is No. 1. When the number of the lamp row corresponding to the lamp row group 212 where the lamp box 213 is located is the number eight, the control unit 7 calculates the predetermined number to be eight according to the number of the lamp row. The positioning sensing signal 552 controls the motor 41 to stop running after receiving the fifth interval sensing signal 551. At this time, the disc 51 is continuously rotated due to the inertia of the motor 41, and the control When the unit 7 receives the eighth interval sensing signal 551, it controls the electromagnet 6 to energize to stop the rotation of the disc 51. At this time, the lamp post body 211, the link 44, the driven gear 43 and the The transmission gear 42 also stops rotating, so that the light row group 212 where the light box 213 is located is stopped at the indicator 32, and the light box 213 to be found flashes to remind the lighter. It should be noted that when the number of the lamp row is one of No. 1 to No. 3, the judgment method of the control unit 7 is slightly different, for example: when the lighter wants to find the lamp where the lamp box 213 is located When the number of the lamp row corresponding to the row group 212 is No. 1, the control unit 7 determines that the positioning sensing signal 552 is received, and after receiving the twenty-second interval sensing signal 551, the control unit 7 controls the motor 41 to stop When the first interval sensing signal 551 after the positioning sensing signal 552 is received again, the electromagnet 6 is energized to stop the rotation of the disc 51, and so on. or the situation on the third.

It should be noted that, in this embodiment, the control unit 7 pre-controls the time point at which the motor 41 stops running before the number of the sensing signals 551 at equal intervals is the same as the predetermined number, which is based on the performance of the motor. If a motor with larger inertia is used, the time point of controlling its stop operation should be carried out earlier. If a motor with small inertia is used, the time point of controlling its stop operation should be delayed. Therefore, this implementation is not used. example is limited.

Through the above description, the advantages and effects of this embodiment can be summarized as follows:

1. Generate the equally spaced sensing signal 551 and the positioning by sensing the light passing through the equally spaced light transmission area 52 and the positioning light transmission area 53 formed on the disk 51 by the single light sensor 55 The sensing signal 552, compared with the existing bright light finding and positioning control device using two different first sensor 131, the second sensor 132 and the physical transmitters 133, can reduce the number of The overall manufacturing cost, installation cost and maintenance cost.
