Description

[Technical Field]

[0001] The present invention relates to a head-mounted lighting unit that is attached to the head of a wearer and can illuminate the area in front of the wearer. [Background technology]

[0002] In medical settings, doctors have traditionally worn loupes or eyeglasses equipped with lighting devices such as LEDs on their heads during surgery or medical examinations. For example, Patent Document 1 proposes a light that is attached to eyeglasses with a clip. In this configuration, the wearer carries a battery that supplies power, and can turn the light on and off by operating a switch on the battery. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3171527 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional configuration of Patent Document 1, the battery is typically stored in a pocket of the doctor's white coat or attached to the doctor's body using a belt or similar. This requires the doctor to search for and operate the battery switch when turning the light on or off, which means that if the doctor takes time to operate the switch, the doctor must temporarily interrupt the medical treatment. Furthermore, during surgery or medical treatment, the doctor's fingers may be contaminated with the patient's blood or bodily fluids, which can lead to the battery getting dirty when the doctor operates the switch.

[0005] The present invention proposes a head-mounted lighting unit that can be easily turned on and off during surgery or medical treatment, and that can prevent blood and other substances from adhering due to the operation. [Means for solving the problem]

[0006] The present invention is a head-mounted lighting unit comprising: a head-mounted section to be worn on the head of a wearer; a lighting member attached to the head-mounted section; a power supply device that supplies power to the lighting member; and a switch device that, when operated by the wearer, switches between an ON state in which power is supplied from the power supply device to the lighting member and an OFF state in which no power is supplied, wherein the switch device comprises a non-contact sensor that detects an object moving within a predetermined detection range without contact, and a switching control means that switches between the ON state and the OFF state each time the non-contact sensor detects an object.

[0007] In this configuration, the wearer can switch the illumination member on and off by moving their body within the detection range of the non-contact sensor. For example, as described above, when a doctor uses the device for surgery or medical treatment, they can turn the illumination member on or off by moving their finger near the non-contact sensor. As described above, the configuration of the present invention allows the wearer to intuitively turn the device on and off without touching the switch, making it easy to operate without taking time to do so even during medical treatment. Furthermore, because the wearer can turn the device on and off without touching it, this configuration prevents blood or other particles from adhering to the switch, as in the conventional configuration described above.

[0008] In the head-mounted lighting unit of the present invention described above, a configuration is proposed in which the non-contact sensor of the switch device is arranged on at least one of the left and right sides of the head-mounted portion, and the detection range of the non-contact sensor is set to include the lateral side of the head.

[0009] With this configuration, while the device is attached to the wearer's head, the lighting member can be turned on / off by moving the wearer's hand next to the head. This makes the on / off operation even easier, improving the effects of the present invention described above. Furthermore, since the on / off operation can only be performed by raising the hand next to the head, there is also the excellent advantage of being able to prevent erroneous operation. [Effects of the Invention]

[0010] As described above, the head-mounted lighting unit of the present invention allows the wearer to intuitively turn on / off the unit without touching a switch, making it easy to operate without taking time to do so even during medical treatment, etc. Furthermore, since it is possible to prevent blood or other substances from adhering to the unit during operation, it also has excellent hygienic effects.

[Figure 3] 10 is a block diagram showing a circuit configuration for supplying power to the illumination member 3. FIG. [Figure 4] 3 is an explanatory diagram showing a detection range 35 of the non-contact sensor 31. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] Embodiments of the present invention will be described with reference to the accompanying drawings. In the embodiments, the front-to-rear direction refers to the front-to-rear direction of a wearer wearing the head-mounted lighting unit 1 of the embodiment, and left and right refer to the left and right of the wearer. Furthermore, in the embodiments, the terms front and front face are used interchangeably.

[0013] 1 and 2, the head-mounted lighting unit 1 of this embodiment comprises a head belt 2 to be worn on the head of the wearer, an illumination member 3 attached to the front center of the head belt 2 via a connecting member 7, left and right magnifying glasses 4, 4 attached to the illumination member 3, and a battery 5 that supplies power to the illumination member 3, and the illumination member 3 and battery 5 are connected by a cable 9. A switch device 6 is provided on the cable 9, and power is supplied from the battery 5 via the switch device 6 to the illumination member 3 via the cable 9. The head belt 2 corresponds to the head-mounted unit of the present invention, and the battery 5 corresponds to the power supply device of the present invention.

[0014] The head belt 2 is adjustable in circumference size, allowing it to fit the wearer's head. The magnifying glass 4 is roughly plate-shaped. The battery 5 is portable and is charged by connecting an adapter, and is provided with a power switch (not shown) that can manually switch power supply on and off. The head belt 2, magnifying glass 4, and battery 5 can each be configured in a conventionally known manner, so detailed explanations will be omitted.

[0015] The connecting member 7 includes a base 11 fixed to the head belt 2, a support rod 12 protruding forward from the base 11, a sliding portion 13 having a vertically long hole through which the support rod 12 is inserted, and an attachment portion 14 provided at the lower end of the sliding portion 13 so as to be tiltable in the vertical direction. A positioning portion 15 is screwed to the tip of the support rod 12, and by fastening the positioning portion 15, the vertical position of the sliding portion 13 relative to the support rod 12 can be fixed, while by releasing the fastening of the positioning portion 15, the sliding portion 13 can be moved in the vertical direction relative to the support rod 12. Furthermore, an illumination member 3 having an LED light is attached to the attachment portion 14, and the cable 9 that supplies power to the LEFD light is connected to it.

[0016] As described above, by releasing the fastening of the positioning portion 15, the connecting member 7 can move the sliding portion 13 and the mounting portion 14 (and the lighting member 3) up and down together, and can be positioned and fixed at a desired position. In addition, by tilting the mounting portion 14 up and down, the lighting direction of the lighting member 3 attached to the mounting portion 14 can be changed.

[0017] The loupes 4, 4 are attached to the mounting portion 14 via the lighting member 3. The left and right loupes 4, 4 are attached to the lighting member 3 by a rod-shaped frame 21 in the left-right direction, and are fixed to both left and right ends of the rod-shaped frame 21. The rod-shaped frame 21 includes a cylindrical frame base 22 fixed to the lighting member 3, and a frame axle 23 rotatably fitted into the frame base 22, and the loupes 4, 4 are fixed to both ends of the frame axle 23 that protrude to the left and right, respectively. With this configuration, the loupes 4, 4 can tilt up and down relative to the lighting member 3, and can also tilt up and down integrally with the lighting member 3 relative to the sliding portion 13.

[0018] 1, 2 and 4, the switch device 6 is attached to the right side of the head belt 2, and includes a non-contact sensor 31 and a switching circuit 32 (see FIG. 3). The switching circuit 32 corresponds to the switching control means according to the present invention.

[0019] The non-contact sensor 31 is a sensor that can detect, without contact, an object that moves within a detection range 35, and is disposed so that the detection range 35 faces outward from the head when the head belt 2 is worn on the head. As a result, when the wearer moves their right hand to the right side of their head, the non-contact sensor detects the movement of the right hand.

[0020] The switching circuit 32 is provided to separate the cable 9 connecting the lighting member 3 and the battery 5, and switches the cable 9 between an ON state in which it is energized and an OFF state in which it is cut off. The non-contact sensor 31 is connected to the switching circuit 32, and switches between the ON state and the OFF state each time a detection signal is received from the non-contact sensor 31. The switch device 6 can switch between supplying and stopping the supply of power to the lighting member 3 by turning the switching circuit 32 ON / OFF each time the non-contact sensor 31 detects an object within the detection range 35, thereby controlling the turning on and off of the LED of the lighting member 3.

[0021] The head-mounted lighting unit 1 of this embodiment can be used by attaching the head belt 2 to the wearer's head. The wearer can turn the lighting element 3 on and off by moving their right hand to the right of their head (detection range 35 of the non-contact sensor 31). This configuration eliminates the need to search for and operate a switch, as with contact-type switches (those that directly operate a button or switch piece). Instead, the lighting element 3 can be operated by intuitively moving their right hand within the detection range 35. Therefore, if this configuration is used in medical settings (such as surgery or medical treatment), doctors can easily turn the lighting element 3 on and off during treatment without having to spend time on the operation. Furthermore, because the operation can be performed without touching the switch, it is possible to prevent the patient's blood, bodily fluids, etc. from adhering to the switch device 6, providing excellent hygienic benefits. Furthermore, because the lighting element 3 can be turned on and off by moving the right hand, etc., to the right of their head (detection range 35 of the non-contact sensor 31), erroneous operation can also be prevented.

[0022] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the dimensions and shapes of the components in the above-described embodiments can be modified as needed.

[0023] In the embodiment, the switch device is disposed on the right side of the head belt, but this is not limiting, and the switch device can also be disposed on the left side. Also, the mounting position of the switch device can be adjusted as appropriate.

[0024] In the embodiment, the device is configured with a head belt to be worn on the head, but this is not limiting and the device may be a type that is worn by hanging it on the ears like a frame of glasses. In this case, it is preferable to attach the switch device to either the left or right side of the frame. [Explanation of symbols]
