Description

[Detailed Description of the Invention] The present invention provides a health lighting device that can be easily used at home.

It is well known that sunlight has excellent health-promoting effects. For example, infrared rays have a sterilizing effect, and ultraviolet rays have a sterilizing effect and an effect of forming vitamin D in the skin. Ultraviolet rays also have a cosmetic effect through tanning. In order to obtain these effects of sunlight, it is generally desirable to sunbathe at resorts, etc., but for most people, this is not possible due to seasonal, time, and economic constraints. The reality is that we cannot always sunbathe. In particular, people who work indoors are prone to poor health due to lack of sun exposure. Therefore, it would be extremely advantageous to be able to easily create the same conditions as sunbathing artificially at home and obtain the same effects as sunbathing.

The present invention was developed in response to such demands, and examples of the present invention will be described below.

The present invention is based on the premise that an ultraviolet lamp and an infrared lamp are installed indoors and irradiates the human body, but in this case, the following conditions must be satisfied.

In particular, excessive exposure to ultraviolet rays can cause various problems to the human body, so it is necessary to prevent this. It also needs to be able to be easily installed in a general household without taking up much space. In view of these points, in this embodiment, the irradiation amount is detected by detecting the erythema that occurs on the skin due to ultraviolet irradiation, and when this irradiation amount exceeds a certain value, the lamp is automatically turned off. I have to. The toilet is also chosen as a place where it can be easily installed.

FIG. 1 shows an example of an embodiment of the present invention, in which two sets of lighting devices 3, 3 are provided on both sides of a rear wall 2 of a toilet in which a toilet bowl 1 is installed. These lighting devices 3 include a support 4, a lamp fixture 5, an ultraviolet lamp 6, an infrared lamp 7, and a second
It is comprised of an erythema detector 10, a control box 11, etc. shown in FIGS. The supports 4 have an arcuate shape, are provided in pairs above and below each lighting device 3, and are fixed to the rear wall 2 by appropriate means. The support 4 is also provided with a plurality of small holes 8 for adjusting the illumination angle. The fixture 5 has a parabolic cross section, and its reflective surface 5a is formed into a fine reflective and scattering surface. Also, cover with aluminum foil, etc.
Ultraviolet and infrared radiation may be effectively reflected. This fixture 5 is attached to the small hole 8 of the support 4 using screws 9. Therefore, by selecting the small hole 8, the mounting angle can be adjusted.
The lamps 6 and 7 are mounted near the focal point of the parabolic surface of the fixture 5. Furthermore, the efficiency can be further increased by forming reflective surfaces using aluminum foil or the like on the rear wall 2 and other wall surfaces in the toilet, and in some cases on the ceiling and floor surfaces, etc., as necessary. In this case, the reflective surface may be formed into a curtain shape, which is normally folded and used by pulling the curtain when necessary.

Next, the erythema detector 10 and control box 11 will be described.

In FIGS. 2 and 3, the erythema detector 10
These include a band 13 having elasticity that can be wrapped around the arm 12, etc., a power switch 14 consisting of a micro switch attached to this band 13, and a band 13.
A support 15 made of thick wire or the like attached to the
Mini lamp 1 attached to the tip of this support 15
6, a phototransistor 17, etc.
In addition, the small lamp 16 and the phototransistor 17 are as follows.
As shown in the figure, it is placed at a position away from the surface of the arm 12. The control box 11 is used by being connected to a commercial AC power source via a power lamp 18.
Lamps 6, 7 and a detector 10 are connected.

When using the illumination device 3 configured as described above, the user sits naked on the toilet bowl 1 and attaches the detector 10 by wrapping it around the arm 12 as shown in FIG. As a result, the power switch 14 is closed, the power is turned on, and the lamps 6, 7 and the miniature lamp 16 are turned on. As a result, the light from the small lamp 16 is reflected off the surface of the arm 12 and the phototransistor 17
However, the amount of light reflected depends on the depth of skin color. Therefore, a current corresponding to the amount of reflection is outputted from the phototransistor 17, and by applying this current to the control box 11, the density of the skin in the initial state of irradiation is stored as an initial value. In this state, the user is irradiated with ultraviolet and infrared rays from the lamps 6 and 7. As the illumination time elapses, erythema begins to appear on the skin, and as a result, the amount of light reflected from the miniature lamp 16 decreases. The density of this erythema increases as it is added to the initially memorized skin density. When this increased amount exceeds a predetermined amount, it is considered that the necessary amount of irradiation within the safe range of ultraviolet and infrared rays has been received.
At this time, the control box 11 automatically cuts off the power to the lamps 6 and 7 to turn them off. According to the above, the light can be turned off when a predetermined amount of irradiation is received, regardless of the darkness of the skin color at the start of irradiation. That is, even if a fair-skinned person or a person with a certain amount of sunburn receives irradiation, the lamps 6 and 7 will automatically turn off when the irradiation amount reaches a predetermined level, thereby preventing excessive exposure to ultraviolet or infrared rays. Can be done.

In this embodiment, the ultraviolet lamp 6 and the infrared lamp 7 are used together, but using only the lamp 6,
It is also possible to irradiate only ultraviolet light. Incidentally, these lamps 6 and 7 may be of about 20W. Further, although the erythema detector 10 is attached to the arm 12, it may be attached to other locations on the human body. For example, if colored glasses are worn during irradiation, the detector 10 may be attached to the colored glasses.

This invention uses an erythema detector to detect when the human body has received a predetermined amount of ultraviolet irradiation from an ultraviolet lamp, and then turns off the ultraviolet lamp, ensuring safety at all times by preventing overexposure to ultraviolet rays. can be used. Further, the light can be turned off when a predetermined amount of irradiation is received, regardless of the darkness of the skin color in the initial state. In addition, since it is easy to install, it can be installed at home and used mainly and lightly whenever desired. Also, not only at home,
It can also be used as a health promotion lighting device in the health industry, beauty industry, sports industry, etc.

[Scope of utility model registration request] It consists of an ultraviolet lamp that irradiates the human body, a detector that is attached to a part of the human body to detect the density of erythema on the skin, and a control circuit that controls the ultraviolet lamp based on a detection signal from the detector. , the control circuit stores a detection signal obtained from the detector indicating the density of the erythema at the start of irradiation with the ultraviolet lamp as an initial value, and stores the detection signal obtained during irradiation with the ultraviolet lamp as an initial value. The health lighting device is configured to detect the amount of increase in the density of the erythema from the initial value based on the amount, and output a signal to turn off the ultraviolet lamp when the amount of increase exceeds a predetermined value.
