Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device for dental lighting equipment,
More specifically, in a dental treatment unit that includes a chair on which a patient is placed for treatment, lighting equipment to illuminate the affected area, etc., the chair, lighting equipment, etc. are configured to be moved to predetermined positions. At the same time, when the automatic setting operation of the chair is completed, the light of the lighting device is turned on, and additionally, the automatic return operation of the chair returns the chair to a predetermined initial position, and at the same time, the light goes out, and then,
The lighting equipment is configured to return to a predetermined initial position, and a series of operations of the treatment chair and the lighting equipment are linked to improve their operability and to improve the efficiency of treatment.

Dental treatment units are already known in which the movement of the treatment chair is automatically brought to a preset position by operating a single button switch. Therefore, when performing dental treatment, lighting equipment and the table must also be placed in certain predetermined positions, but at present, these lighting equipment and the table are manually operated by the operator (doctor). Most of them are. In addition, the treatment chair can be returned to the predetermined initial position by operating an automatic return button switch, but even in this case, the surgeon or assistant must manually operate the lighting equipment and table. I was careful not to hit the chair that was automatically returning to its original position, or the patient sitting on the chair. As described above, in conventional dental treatment units, although the treatment chair is automatically controlled, the lighting equipment and table still have to be operated by hand, resulting in very poor operability. .

The present invention has been made in view of the above-mentioned circumstances, and is particularly applicable to conventional chairs, such as vertically movable chairs.
The lighting equipment and the table part are also operated as part of the chair in relation to the movements of the chair, such as undulating the back plate, auto-return, memory setting, etc., thereby improving the operability of the dental treatment unit. The aim is to improve the efficiency of treatments.

The figure is an overall configuration diagram for explaining one embodiment of the present invention, in which 10 is a central control device, 20 is a chair vertical movement control section, 30 is a chair elevation control section, 40 is a lighting equipment control section, 50 is an operation switch part, 60 is a light on/off switch, 70 is a table part control part, M is an automatically controllable motor or cylinder,
R is a position sensor such as a potentiometer, magnetic sensor, optical sensor, rotary encoder, etc. that is interlocked with the motor or cylinder, and as shown in the figure, it is located at at least one joint of the moving mechanism of the illumination light 41 and the table 71. A motor M and a potentiometer R are attached above. The height and degree of undulation of the treatment chair vary depending on the body shape of the surgeon.
First, it is necessary to position the chair in a position that suits the surgeon's body type, and this position is first stored in the memory of the central control unit. This memory setting operation begins by switching the vertical movement of the chair with SW ₅₁ and SW ₅₂ .
Adjust the chair back to the desired height using switches SW ₅₃ and SW ₅₄ , then manually set the lighting equipment and table to the position that is most convenient for diagnosis. In this state, press the memory storage switch SW ₅₉ to store the data in a predetermined memory (RAM) in the central control unit 10. That is, as described above, the top and bottom of the chair,
When the undulation of the back plate, the position of the lighting equipment, and the table part are set to the desired state, each state position is detected as a voltage value by the respective potentiometer, and when the memory switch SW ₅₈ is pressed, the corresponding A/ D
The converted values are stored in the memory of the central controller 10. In this way, once the optimal positions of the treatment chair, lighting equipment, and table are memorized in memory, from then on, when switch SW ₅₇ is pressed, the current values of the potentiometers of each motor will be set to the memory. The chair is driven to the values stored in memory, and the chair's up and down, up and down positions, and the positions of lighting equipment and table parts are all automatically set to the positions stored in memory as described above, and at the same time, the light 41 is lit. Note that this light 41 can also be turned on and off manually using a light on/off switch 60. The light 41 is turned off by pressing the auto return switch SW ₅₆ , and then the chair is returned to the initial state (lowest position) of the limit switch SW ₂₂ , and at the same time, the lighting equipment is turned off to the limit switch.
Up to SW ₄₂ , table section limit switch SW ₇₂
Return to initial state. It should be noted that during the auto-set and auto-return operations described above, it is natural that _the lighting equipment and table section are designed to avoid hitting the chair and _patient . When the A/D conversion value of the back plate is compared with the A/D number of the lighting equipment and the A/D number of the table part in the direction of rising, if there is a match, compare these lighting equipment and A/D number. All you have to do is control the table part and return it to a place where it won't hit.

As is clear from the above description, according to the present invention, the lighting equipment is operated in series in conjunction with the movement of the treatment chair, which greatly improves operability and increases treatment efficiency. .
