Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet over-irradiation notification which can be carried, for example, when the user is out of the office, so that when the skin is approaching a state where the skin is adversely affected by the ultraviolet irradiation, the effect can be alerted. About the vessel.

[0002]

2. Description of the Related Art Ultraviolet irradiation is known to have various effects on human skin. Normally, most of the ultraviolet light that humans receive is sunlight. Among the ultraviolet rays contained in the sun's rays, long-wavelength ultraviolet rays (about 400 to 320 nm) oxidize reduced melanin on the surface of the skin and directly cause sunburn. In addition, medium-wavelength ultraviolet light (about 320 to 280 nm) causes acute inflammation (red spots) and burns on the skin.

In particular, the energy of long-wave ultraviolet light reaches the dermis, causing microchronic changes in the elastic fibers in the blood vessel walls and connective tissues, and these changes do not lead to accelerated aging of the skin. It is believed that it enhances the degenerative action of ultraviolet light on the skin and contributes to the development and worsening of spots and freckles.

[0004] Therefore, it prevents the promotion of aging of the skin,
Protecting the skin from ultraviolet light is extremely important to prevent the occurrence and deterioration of freckles. At present, in order to protect the skin from ultraviolet rays, a hat is worn when going out, or a cosmetic (a cosmetic containing an ultraviolet absorbent) is applied to the exposed skin surface.

[0005]

Various cosmetics (cosmetics containing an ultraviolet absorber) used as a measure for protecting the skin from ultraviolet rays have a certain degree of ultraviolet absorbing effect, but have low stability to light and heat. As a result, the ultraviolet ray absorbing effect changes in a reduced manner.

[0006] Therefore, even when the cosmetic is applied to the skin, a sufficient effect of cutting off ultraviolet rays cannot be obtained in a state where the cosmetic is exposed to sunlight for a long time. Conversely, due to erroneous recognition that the ultraviolet rays have been cut, the result is that the state of being over-irradiated with ultraviolet rays (receiving an amount of ultraviolet rays that has an adverse effect on the skin) is continued without being noticed.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and detects a charging capacity of a power storage means charged by a solar cell, thereby approaching a state of receiving an amount of ultraviolet irradiation that adversely affects the skin. Alerts you that you are
Provided is an ultraviolet over-irradiation alarm capable of protecting the skin from ultraviolet irradiation.

[0008]

In order to achieve this object, an ultraviolet over-irradiation alarm according to the present invention has the following configuration. The ultraviolet over-irradiation alarm includes a main body case having a mounting portion in an appropriate position, a solar cell provided in the main body case, and a power storage means provided in the main body case for storing energy generated by the solar cell. When the charge capacity of the power storage means reaches a predetermined charge capacity, the ultraviolet over-irradiation determining means determines that the state is the ultraviolet over-irradiation state. And a notifying means for notifying the user.

[0009] In the ultraviolet over-irradiation alarm having such a configuration, for example, when a cosmetic (an ultraviolet absorbent-containing cosmetic) is applied to the exposed skin when going out, the surface of the solar cell (body) Transparent surface protruding from the case)
Apply the same cosmetic. Sun rays enter the solar cell through the cosmetic-applied surface.

[0010] Therefore, in relation to the irradiation of sunlight, the skin surface to which the cosmetic is applied and the light receiving surface of the solar cell can be made to have the same environmental conditions. That is, the amount of ultraviolet absorption differs between the skin surface not coated with the cosmetic and the skin surface coated with the cosmetic. Therefore, by setting the amount of incident sunlight (the amount of ultraviolet rays) to the solar cell to be equivalent to the actual skin surface, it is possible to recognize a correct ultraviolet over-irradiation state.

When sunlight passes through the cosmetic application surface and enters the light receiving surface of the solar cell, the power storage means is charged. When the charging capacity of the power storage means reaches, for example, a fully charged state, it is notified that the ultraviolet light is over-irradiated (a state immediately before receiving an amount of ultraviolet irradiation that has an adverse effect on the skin). For example, the LED is flashed.

Therefore, by moving to a place where ultraviolet rays are hardly received, such as indoors, by this notification, it is possible to escape from adverse effects on the skin due to ultraviolet rays. In other words, it is possible to prevent skin aging due to UV irradiation.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an ultraviolet over-irradiation alarm according to the present invention.

FIG. 1 is a perspective view showing an embodiment in which the ultraviolet over-irradiation alarm is a bracelet-shaped accessory. The ultraviolet over-irradiation alarm includes a main body case 1 having a light-entering transparent plate 2, a solar cell 3, a power storage unit 4, an ultraviolet-over-irradiation determination unit 5, and an alarm unit 6.

The main body case 1 is formed of a material such as a synthetic resin material, and is formed into a hollow case body having an empty space 12 provided therein and an opening 11 communicating with the empty space 12 in the upper surface. ing. The main body case 1 is provided with a band (mounting portion) 13 for mounting, and a wrist or an arm (upper arm).
It is designed to be detachably attached to the like. The mounting portion 13 of the embodiment is, for example, a curved band portion biased by a spring, and has a configuration in which the degree of bending can expand and contract against the spring force.

The light-entering transparent plate 2 is fitted and fixed to the upper opening 11 of the main body case 1 in a closed state. The light-entering transparent plate 2 is, for example, a transparent plastic plate or a transparent glass plate, and is fixed in a liquid-tight manner.

The light-entering transparent plate 2 has a surface portion on which a cosmetic (a cosmetic containing an ultraviolet absorber) A is applied.
a. For example, when the cosmetic A is applied to the exposed skin (face) of the user, the same cosmetic A is applied to the application surface 2 a of the light-transmitting transparent plate 2. Thereby, the light receiving surface of the solar cell 3 on which sunlight enters and the skin surface on which the cosmetic A is applied can be set to an equivalent environmental state. That is, cosmetic A
May be applied to the surface of the solar cell 3, but in the embodiment, the surface of the light-entering transparent plate 2 is used as the cosmetic application surface. In this case, the operation of applying and wiping the cosmetic A is further simplified.

FIG. 2 is a cross-sectional view showing the ultraviolet over-irradiation alarm. The solar cell 3 is built in the main body case 1. That is, the light receiving surface 31 is fixed in the main body case (vacant space portion 12) 1 so as to face the transparent glass plate 2.

As the solar cell 3, a known silicon solar cell or amorphous Si solar cell or the like is used, and a plurality of solar cells (elements) are connected. That is,
Assuming that the output voltage of one element is about 0.5 V, a large number of these elements are connected in series or in parallel to obtain necessary voltages and currents.

The output voltage of the solar cell 3 is, for example, a charging rate of the power storage means 4 described later, that is, a charging speed (time for charging the rated capacity) of about 2 hours in a maximum state (in a complete solar radiation state). Set to be.

As the power storage means 4, a capacitor or a secondary battery such as a lithium ion battery is used. In the embodiment, a button type lithium ion battery is used. The lithium ion battery 4 is disposed and fixed below the solar cell 3 in the vacant space 12 of the main body case 1, that is, on the side opposite to the light-entering transparent plate 2, and is electrically connected to the electrode surface of the solar cell 3. I have.

FIG. 3 is a block diagram showing an example of the circuit configuration of the ultraviolet over-irradiation alarm. The ultraviolet over-irradiation alarm includes a solar cell 3 as a power generation unit, a lithium ion battery 4 charged by the solar cell 3, and an ultraviolet over-irradiation when the charge capacity of the lithium ion battery 4 reaches a predetermined charge capacity. The apparatus comprises an ultraviolet over-irradiation determining means 5 for determining the state, and an informing means 6 for receiving and outputting a determination output from the ultraviolet over-irradiation determining means 5.

As shown in the specific circuit diagram of FIG.
Energy generated by sunlight entering the light receiving surface 31 of the solar cell 3 is supplied to the lithium ion battery 4 and charged. The overcharge prevention circuit 71 is for preventing overcharge and protecting the battery 4, and includes a backflow prevention element 53,
Reference numerals 54 and 55 denote diodes for preventing a current from flowing back to the solar cell 3.

The above-mentioned means (CPU) 5
Is to determine whether or not the charge capacity of the lithium ion battery 4 has reached a predetermined charge capacity, and when the charge capacity has reached, the state is over-irradiated with ultraviolet light (a state close to the stage of receiving ultraviolet irradiation that adversely affects the skin). It is determined that there is.

In the embodiment, the predetermined charging capacity is set to, for example, an amp hour (charging amount) when charging is performed for about 2 hours in a strong sunlight ray on a hot summer day. In the embodiment, for example, the charging capacity is set so that the lithium ion battery 4 is fully charged.

Incidentally, the charging operation of the solar cell 3 varies in accordance with the irradiation amount of sunlight, and the voltage varies in accordance with the charging amount. In other words, the larger the amount of irradiation of the solar ray to the solar cell 3, the higher the power generation capacity, and the voltage of the power storage means 4 increases along with the charged amount of electricity. From this, it means that the longer the charging capacity of the power storage unit 4 is, the longer the time of being irradiated with strong sunlight (ultraviolet rays).

Although various methods can be considered for measuring the charge capacity of the lithium ion battery 4, the embodiment employs the simplest method. (See FIG. 4). A current flowing through the resistor 51 disposed in the charging loop of the lithium-ion battery 4, that is, the resistor 51 corresponding to the charging capacity of the lithium-ion battery 4, is detected and converted into a voltage by the A / D converter 52. Irradiation determination means (CPU) 5
Output to

The CPU 5 calculates the charge capacity of the lithium ion battery 4 based on the voltage information, determines whether the charge capacity has reached the predetermined charge capacity, and when the charge capacity has reached the predetermined charge capacity. Notifying means 6
And a function of driving and controlling the notifying means 6.

In the embodiment, the notification means 6 is an LED provided in a display unit 14 provided in the main body case 1. By blinking the LED 6 for example, the fact that the amount of UV irradiation that has an adverse effect on the skin is approached, that is, the state of excessive UV irradiation, is alerted and notified. The display unit 14 is set so that the lighting state can be seen well even in a place with strong sunlight by using a dark plastic plate as the surface plate 14a and incorporating one or more LEDs 6 therein.

The notifying means 6 is not limited to the LED, but is provided with, for example, a plurality of segments (SEG), and determines the amount of ultraviolet irradiation in a stepwise manner according to the degree of charge (small / medium / large). The display may be an LCD display. The notifying means 6 employs, for example, a known voice output device having a voice memory, and "the amount of ultraviolet irradiation is large and is dangerous to the skin. Please enter the room. Or “There is a risk of heat stroke. Please enter the room. And the like.

In the ultraviolet over-irradiation alarm having such a configuration, when going out, it is carried as, for example, a wristband. When the cosmetic (a cosmetic containing an ultraviolet absorbent) A is applied to the exposed skin, the application surface (surface) 2a of the light-receiving transparent plate 2
Is applied with the same cosmetic A. Therefore, when the cosmetic is not applied to the skin, the surface 2a remains as it is. The sunlight is incident on the light-entering transparent plate 2 and the solar cell 3 through the cosmetic (cosmetic application surface 2a) A. Therefore, regarding the irradiation of sunlight (ultraviolet light irradiation), the light receiving surface 31 of the solar cell 3 and the skin surface can be set in exactly the same environmental state, and an appropriate ultraviolet overirradiation state similar to the actual skin state can be obtained. It will be able to inform.

When sunlight passes through the cosmetic application surface 2a and enters the light receiving surface 31 of the solar cell 3 via the light incident transparent plate 2, the lithium ion battery 4 is charged. In the embodiment, the setting is such that the charge capacity of the lithium-ion battery 4 is initially discharged to "0" or to an electric power close to "0" (at the time of going out, that is, at the time of start).

When the charging of the lithium ion battery 4 is started, the ultraviolet radiation excessive irradiation determining means (CPU) 5 determines whether or not the charging capacity of the lithium ion battery 4 has reached a predetermined charging capacity. That is, it is determined whether or not the lithium ion battery 4 has reached a predetermined value in a fully charged state.

The time when the lithium ion battery 4 is determined to be fully charged is defined as “ampere hour when charging is performed for about 2 hours under a strong sunshine irradiation state on a hot summer day ( Charging amount). " With this charge, the person carrying this instrument was exposed to the strong sunlight of midsummer for about 2 hours. In other words, it means that it has been irradiated with ultraviolet rays. It is determined that the amount of ultraviolet light is sufficient to adversely affect the skin, and is determined to be excessively irradiated with ultraviolet light.

The notification means 6 receives the judgment output of the CPU 5 and turns on and off the LED 6. That is, body case 1
The LED 6 of the display unit 14 is turned on. Since the surface plate 14a of the display unit 14 is dark, the lighting of the LED 6 can be clearly seen even when the illuminance of sunlight is large.

The wearer of this apparatus knows that the user is receiving a sufficient amount of ultraviolet radiation to adversely affect the skin by seeing the lighting notification, and moves to an indoor area where the influence of the ultraviolet radiation is small. Thus, even if you spend a lot of time outdoors, for example in sports games, without realizing it,
Being alerted to UV exposure can protect the skin from UV radiation.

In the embodiment, an example is shown in which the ultraviolet over-irradiation alarm has a bracelet structure.
However, the present invention is not limited to this, and it may be a jewelry structure such as a brooch or a necklace. In the case of a broach or the like, it can be attached to, for example, a child's hat or a worn shirt, and there is no risk of loss.

Further, in the embodiment, the example has been described in which the "predetermined charge capacity" is a fully charged state of the power storage means and the initial charge capacity is "0" as a setting condition. The present invention is not limited to this. Using a large-capacity power storage means, the remaining capacity is stored in the memory, and the CPU 5 adds, for example, “the charging capacity obtained when the battery is charged for about 2 hours under sunlight” to the remaining capacity. A method may be used in which it is determined whether or not the charging capacity of the power storage means has reached the capacity (predetermined charging capacity). In this case, the inconvenience of initially setting the charge state to “0” as in the embodiment is eliminated.

[0039]

According to the present invention, as described above, a light-entering transparent plate on which a cosmetic can be applied is provided in a main body case containing a solar cell and a power storage means, and the charging capacity of the power storage means is a predetermined charging capacity. When it arrives, it is determined that it is in an over-irradiated state, and it is notified by the notification means. The fact that the object is in the irradiation state is notified by an alarm. Therefore, the wearer can protect the skin from ultraviolet rays by moving to the indoors where the influence of the ultraviolet radiation is small by notification. Also, if cosmetics containing an ultraviolet absorber are applied to the exposed skin, the same cosmetics can be applied to the surface of the light-entering transparent plate, so that the light-receiving surface of the solar cell can be exposed to sunlight. And the exposed skin can have the same environmental conditions.
Therefore, the present invention has an excellent effect of achieving the object of the present invention, for example, it is possible to appropriately judge an over-irradiated state of an ultraviolet ray which is similar to an actual environment.
