Description

  The present invention relates to a mirror with a light source having a dimming and toning function, and is suitable for use in coloring in a beauty salon, for example.

  2. Description of the Related Art Conventionally, a mirror apparatus with illumination is known in order to improve the appearance of a face and the like projected on a mirror (see Patent Document 1). For example, a cosmetic display case is equipped with a mirror that reflects the customer's face so that the customer can actually take out and try out the product that the customer wants, not just displaying the product. The customer can check the beauty effect of the product by putting the product in his hand on his face and looking into the mirror. On the other hand, the upper part of the cosmetic display case is provided with lighting for illuminating the product. If the face of a trial product is reflected in a mirror under such illumination, the shadow will be captured by the use of a shadow on the customer's face due to the illumination, and the cosmetic effect of the product cannot be fully confirmed. .

  Therefore, the mirror apparatus with illumination disclosed in Patent Document 1 emits light in a scattered state from the entire periphery of the mirror main body through a light transmitting body, and projects the entire face. As a result, the shadows and shadows of the face due to external light are canceled out, so that unnecessary shading is prevented from occurring on the face.

  However, although there is an effect of canceling shadows and shadows of the face due to external light, there is a problem that the influence of color due to external light cannot be eliminated. For example, in a beauty salon, a mirror with a light source in which an incandescent lamp is charged is used as a light collector as in a conventional mirrored device with illumination. When coloring is performed using such a mirror with a light source in a beauty salon, the color projected on the mirror after the completion of coloring is affected by the illumination light of the incandescent light and hits the actual sunlight. It may be projected with a different color. In this case, even if an explanation to that effect is received from the beautician, it is difficult for the customer to imagine the color. There are cases where you can search for similar colors in samples and magazines and share the finished image with customers, but there is a gap from the actual colors. In addition, after finishing coloring, there was a demand to check the finished color according to the situation such as sunlight, indoor space, party space.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a mirror with a light source that can clearly have a coloring image desired by a customer reflected in the mirror and can confirm the color finish even in various situations. It is in.

The mirror 11 is provided on the mating surface side of the first frame 13 and the second frame 14. The frame 12 provided with the mirror 11 on the mating surface side is formed with a size and weight that can be easily carried by one person.

  Moreover, as shown in FIG. 1, although the 1st frame 13 and the 2nd frame 14 are formed by the substantially same thickness, the frame 12 is a frame which concerns on the modification shown in FIG. As shown in FIG. 17, the first frame 18 may be formed to be thin, and the accommodating portion 16 may be formed only in the second frame 19. Further, the frame body 12 may be formed with a handle portion 20 that facilitates carrying as shown in FIG.

The first frame body 13 and the second frame body 14 are provided with a plurality of LEDs 22 on a frame surface 21 parallel to the mirror 11. The LEDs 22 are arranged at predetermined intervals along each side of the first frame 13 and the second frame 14. That is, it is provided so as to surround the mirror 11. Thereby, it can shine so that a shadow may become clear, and a favorable lighting effect can be acquired. As shown in FIG. 2, the LEDs 22 are embedded in the frame surface 21 so as not to interfere with the facing LED 22 or the facing frame surface 21 when the frame 12 is folded.
In addition, since the irradiation light will become too strong when one side part of the frame 12 connected by the rotating shaft 15 is provided with each LED22, as shown in the figure, for example, the LED 22 on the second frame side is omitted. Good.

  A scene changeover switch 24 is provided on the frame upper surface 23 of the first frame 13, and the scene changeover switch 24 has a plurality of scene changeover contacts 25. The scene-specific switching contact 25 includes, for example, a first button 26 that reproduces a scene in sunlight, a second button 27 that reproduces an indoor space scene, a third button 28 that reproduces a party space scene, and power off. And the fourth button 29. The scene changeover switch 24 may be a rotary switch (not shown) in which a scene-specific changeover contact 25 is opened and closed depending on the rotation position, in addition to providing a plurality of buttons as shown in the figure.

As shown in FIG. 2, a control unit 32 having a dimming circuit 30 and a toning circuit 31 and a power supply circuit 33 are accommodated in the internal space of the first frame 13. The second frame 14 is provided with a charging port 34, a battery 35, an illuminance sensor 36, a color temperature sensor 37, and a limit switch 38.
The arrangement positions of the control unit 32, the charging port 34, the battery 35, the illuminance detection sensor 36, the color temperature detection sensor 37, and the limit switch 38 are merely examples, and can be accommodated on an arbitrary frame side.

FIG. 4 is a block diagram showing functional parts of the light source mirror 10 shown in FIG.
The charging port 34 is connected to the power supply circuit 33. A limit switch 38, a battery 35, and a control unit 32 are connected to the power supply circuit 33. When a commercial power source is connected to the charging port 34, the power supply circuit 33 converts a low-frequency alternating current into a direct current smoothed by a full-wave rectifier and a smoothing capacitor, and further converts the direct current into a high frequency by a high-frequency inverter (not shown). Thus, the LED 22 can be driven at a high frequency. The power supply circuit 33 also charges the battery 35 when a commercial power source is connected to the charging port 34. The power supply circuit 33 supplies power from the battery 35 to the control unit 32 in a state where a commercial power supply is not connected to the charging port 34.

  The limit switch 38 is activated by the folding operation of the frame body 12 to turn off the LED 22. When the frame 12 is folded, the limit switch 38 is operated, the power supply to the control unit 32 and the LED 22 is cut off, and the LED 22 is automatically turned off.

The LED 22 includes at least two chips 39 that are provided on the frame 12 and emit light in different colors. In this embodiment, the LED chip of three colors of the R color LED chip 40, the G color LED chip 41, and the B color LED chip 42 is provided. In each LED 22, the R color LED chip 40, the G color LED chip 41, and the B color LED chip 42 are individually driven and controlled by the color adjustment circuit 31 of the control unit 32, and adjustment of color temperature, that is, color adjustment is possible. It has become.
Here, toning refers to switching and emitting a plurality of types of light when obtaining one type of emission color by mixing a plurality of types of light having different emission colors.

  Although not shown in the figure, the toning by the LED 22 is realized even by using a single color chip 39 by using color conversion means such as a phosphor. In this case, for example, white light is emitted from the first color conversion region by emitting blue light only from the chip 39 corresponding to the first color conversion region. By emitting blue light only from the other chip 39 corresponding to the second color conversion area, light bulb color light is emitted outward from the second color conversion area. Further, by emitting blue light from the two chips 39, light having a color intermediate between white and light bulb color can be emitted from the first color conversion region and the second color conversion region to the outside. Thereby, it is possible to perform toning by switching and emitting light of a plurality of types of colors.

  The control unit 32 adjusts the color of the LED 22 according to the scene switched by the scene switch 24 based on the detection value of the color temperature sensor 37. At this time, it is preferable that the control unit 32 simultaneously refers to the detection value of the illuminance sensor 36. By providing the illuminance sensor 36, the light source mirror 10 can be configured such that the control unit 32 automatically performs dimming control of the LED 22 according to the detected brightness of the surrounding environment.

  When the control unit 32 detects the frame opening signal of the limit switch 38 that operates by opening the frame 12, the control unit 32 detects the color temperature of the surrounding environment from the color temperature sensing sensor 37, and according to the color temperature of the surrounding environment, Toning control of the LED 22 is performed so that the color temperature of the switching scene is reproduced.

Next, the operation of the mirror 10 with the light source configured as described above will be described.
In the mirror 10 with a light source, when the control unit 32 is driven, the illuminance of external light is detected by the light control circuit 30, and the color temperature of the external light is detected by the color temperature sensor 37. The control unit 32 determines a desired switching scene from the scene-specific switching contact 25 where the scene switching switch 24 is closed, and sets illuminance and color temperature according to the switching scene.

  The control unit 32 refers to the detected illuminance and color temperature of the external light, and controls each chip of the LED 22 with the dimming circuit 30 and the toning circuit 31 so that the illuminance and color temperature according to the desired switching scene are obtained. 39 is controlled. As a result, the actual color with the influence of the color caused by the external light canceled is displayed on the mirror 11. Moreover, the actual color in each switching scene (sunlight, indoor space, party space, etc.) is displayed on the mirror 11 only by switching the scene switch 24.

  The limit switch 38 is activated by the folding operation of the frame body 12 to turn off the LED 22. When the frame 12 is folded, the limit switch 38 is operated, the power supply to the control unit 32 and the LED 22 is cut off, and the LED 22 is automatically turned off. As a result, the open / closed state of the scene-specific switching contact 25 in the scene changeover switch 24 can be maintained, so that driving can be started in the switching scene at the end of the previous use at the next use.

  Further, when the frame 12 is opened from the extinguished state, the limit switch 38 is operated, and power is supplied to the control unit 32 and the LED 22 to start driving. At this time, the control unit 32 detects the color temperature of the surrounding environment by the color temperature sensor 37 simultaneously with the start of driving, and refers to the detected color temperature so that the color temperature corresponds to the setting switching scene. The drive control of each chip 39 of the LED 22 is performed. That is, at the same time as the frame 12 is opened, the color temperature of each switching scene is automatically reproduced by the color temperature of the surrounding environment and the color temperature of the LED 22.

  By having such an effect, the mirror 10 with a light source can be a hairdresser's proposal support tool. It will be possible to easily and accurately color the work flow so far without bothering the customer and the hairdresser. Further, by using the LED 22 as the light source, it is possible to realize a light weight and a thin shape, and to carry it easily.

  Therefore, according to the mirror 10 with a light source according to the present embodiment, a customer can clearly have a desired coloring image reflected in the mirror 11 and the finished color can be confirmed in various situations.
