Description

  The present invention relates to a medical lighting device used for color therapy (color therapy).

  Conventionally, lighting devices used in color therapy are disclosed in Patent Documents 1 and 2. The technology of Patent Document 1 can project a light source assigned with red, green, blue, etc. on the front of the main body of the apparatus horizontally and a red, green, blue light source in the apparatus and project it on the front screen. This is the structure. The technique of Patent Document 2 has a structure in which a plurality of light emitting elements made of red, green, and blue light emitting diodes are radially arranged in a transparent or translucent cylindrical body.

By the way, since each of the above-described techniques includes light sources of respective colors in one apparatus main body, there is a problem that the apparatus is enlarged, and there are restrictions on the placement location and the posture of the patient. In addition, these lighting devices are generally driven by an AC power supply, but there is also a problem that the electromagnetic waves of the AC dimmer that adjusts the color and brightness adversely affect the device and the human body (brain and optic nerve). .

  The problem to be solved by the present invention is to solve these conventional problems, can be installed in any place and can be treated with an easy posture, and also prevents the electromagnetic waves and blinking to reduce irritation to the brain and optic nerve An object of the present invention is to provide a medical lighting device.

The configuration of the present invention that solves this problem is as follows.
1) In a medical lighting device used for therapy that stimulates and activates the body by giving light of a specific color to the sight, three primary color filters are attached to the three illuminated spotlights with incandescent bulbs. , A control means for providing each of the spotlights with a direct current obtained by rectifying and smoothing the alternating current, and irradiating any colored light spot by combining any of the spotlights or a combination thereof through each power supply circuit The medical lighting device is characterized by comprising:

  According to the present invention, since the light sources of the three primary colors are independent as spotlights, they can be easily installed at an arbitrary place by standing on a stand or suspended from a ceiling, and without requiring a patient to have a predetermined posture. Can be treated with a proper posture. In addition, since the power supply circuit is driven by direct current obtained by rectifying and smoothing alternating current, the electromagnetic wave and blinking can be eliminated to reduce irritation to the patient, and more effective treatment can be performed.

  The medical lighting device of the present invention is driven by an AC power source. In this case, a rectifier circuit that rectifies and smoothes the AC current is provided in the power source circuit, and the spotlight is driven by the obtained pulsating direct current to generate electromagnetic waves. It also reduces the stimulation of the brain and optic nerve by eliminating flashing. Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is an explanatory diagram of the medical lighting device of the embodiment, FIG. 2 is a block diagram of the medical lighting device of the embodiment, and FIG. 3 is a power supply circuit diagram of the embodiment. In the figure, 1 is a medical lighting device, 2 is a spotlight, 3 is a color filter, 4 is a power supply circuit, 5 is an interface, and 6 is a computer.

  As shown in FIGS. 1 and 2, the medical lighting device 1 according to the present embodiment has three primary color filters 3 of red, green, and blue attached to the irradiation surface of three spotlights 2 in which incandescent bulbs 4q are incorporated. A computer 6 is provided via the interface 5 for providing a power source circuit 4 for driving each spotlight 2 and spot-irradiating an arbitrary color light by combining any of the spotlights 2 or a combination thereof through each power source circuit 4. Connected. Each spotlight 2 is installed, for example, on a stand (not shown) or suspended on the ceiling so that each light is irradiated to the patient.

  The power supply circuit 4 is assembled as shown in FIG. 3, in which 4a is an AC power supply, 4b is a waveform shaping rectifier diode, 4c is a noise preventing capacitor, 4d is a filter inductor, 4e is an inrush current preventing resistor, 4f Is a charging / discharging capacitor, 4g is a bleeder resistor, 4h is a voltage drop resistor, 4i is a backflow prevention capacitor, 4j is a smoothing capacitor, 4k is a voltage adjustment volume, 4m is a manual / automatic switch, 4n is for biasing A resistor, 4p is a dimming semiconductor, 4q is an incandescent lamp, and 4r is a digital / analog converter.

  In the present embodiment, when an alternating current is supplied from the alternating current power source 4a, the waveform shaping rectifier diode 4b rectifies it and smoothes it with the smoothing capacitor 4j. The digital signal from the computer 6 is converted into an analog signal by the digital / analog converter 4r, and light of any color / lightness according to the patient's condition is obtained by switching on / off each light bulb 4q and adjusting the lightness. Irradiate. When the manual / automatic switch 4m is switched to the manual side, the brightness can be individually adjusted by the voltage adjusting volume 4k provided for each spotlight 2.

  Since the present embodiment is configured as described above, the light sources of the three primary colors are independent as the spotlight 2, so that they can be easily installed at any place by standing on a stand or suspended from a ceiling, It is possible to perform treatment with an easy posture without requiring any posture. In addition, since the power supply circuit 4 is driven by direct current obtained by rectifying and smoothing alternating current, it is possible to eliminate electromagnetic waves and blinking, reduce stimulation to the patient, and perform more effective treatment.

  The medical lighting device of the present invention is used to reduce irritation of eyes and brain involved in medicine, design, and computers.

It is explanatory drawing of the medical illuminating device of an Example. It is a block diagram of the medical illuminating device of an Example. It is a power supply circuit diagram of an Example.
