Description

  The present invention relates to a luminaire using a surface light source with less shading, which is easily attached to the edge or center of a mirror such as a mirror stand, a hand mirror, or a mirror.

  Conventionally, in order to make up in a dark place, a compact case with a lighting device or a hand mirror has been devised.

  However, when an illuminating device is attached to a compact case or a hand mirror, the illumination tends to be a point light source, and it is difficult to illuminate a wide area uniformly brightly. In particular, in the case of a compact case, the light source and the mirror are adjacent to each other, and the user feels dazzling. In addition, there are many inventions of battery-powered lighting, but with this method, the battery power supply is insufficient in both usage time and brightness.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a use state in which a detachable annular luminaire is attached to a mirror. The clip portion 10 includes a fixed clip portion 11 fixed to the annular light diffusion portion 1 and a movable clip portion 12 with a spring for sandwiching the mirror. By attaching the clip part 10 so as to be sandwiched between the edges of the mirror, the annular light diffusing part 1 can be detachably attached to the edge of the mirror.
Similar to the clothespin, the movable clip portion 12 rotates and tightens the movable clip portion 12 with the force of a spring to hold a removable annular lighting fixture. The tip of the fixed clip portion 11 that sandwiches the mirror and the tip of the movable portion 12 that comes into contact with the mirror is provided with a non-slip material such as resin to prevent it from easily shifting.

FIG. 2 is a perspective view of the detachable annular lighting fixture described in (1) and (2) as seen from the front side. The detachable annular luminaire includes an annular light diffusing portion 1 for diffusing the light of the LED 5 shown in FIG. 3, a movable clip portion 12 containing electronic components such as a fixed clip portion 11 and an LED control circuit. Become. An LED drive circuit for controlling the brightness of the light source, a switch, and a socket for an AC adapter are contained in the internal space 6 of the fixed clip portion 11.
Reference numeral 13 denotes a radiator for a light source brightness control device. Reference numeral 14 denotes an AC adapter socket.
Although the makeup time is about 10 minutes, it is difficult to obtain a light amount for makeup with a battery, and it is difficult to light for a long time. Therefore, constant electricity is supplied by the AC adapter. Since the brightness control device generates a considerable amount of heat depending on the type of the circuit, the radiator 13 can be attached. The brightness of the LED is controlled by voltage, current, the blinking interval of current pulses, or a combination of these.
The larger the number of LEDs attached to the annular light diffusing unit 1, the brighter and the average beautiful light.

The exploded perspective view of FIG. 3 is the figure which looked at the light-diffusion part of the removable annular lighting fixture of this invention from the back side. On the back side of the annular light diffusing unit 1, a concave lens-shaped depression or groove 2 serving as a concave lens is cut. The LED is placed on the back cover / LED base 3 so that the light emitting surface of the LED faces the concave depression or groove 2.
The back cover / LED base 3 is a cover for holding the LED and covering the groove of the concave lens type. The back cover / LED base 3 has a plurality of heat exhaust holes 4 that serve to exhaust heat from the LEDs.

FIG. 4 is a cross-sectional view of the detachable annular luminaire described in (1) and (2) taken along A and A. FIG.
A concave lens-shaped depression or a concave lens-shaped groove 2 is cut on the back side of the annular light diffusing portion 1, and the LED light emitting surface is disposed so as to face the concave lens surface. With this concave lens, the light emitted from the LED is diffused and a large area can be illuminated.
Since the concave lens-shaped depression or concave lens-shaped groove 2 is close to the light emitting source of the LED, a strong concave lens or concave lens-shaped groove is required.
The rectangular shape and size of the cross-section of the annular light diffusing portion 1 varies depending on the size of the built-in LED and the strength of the annular light diffusing portion, but the light emitting surface can be widened. A rectangular cross section with a wide light emitting surface side (surface side) is preferable.

In order to further diffuse the light, the surface on the front side of the light diffusing portion 1 is made of frosted glass or the light diffusing portion 1 itself is made of a translucent resin to further diffuse the light.
The term “ground glass” as used herein refers to the degree of transparency that is obtained by sandblasting transparent acrylic with alumina sand # 80 to # 120, and is not a light ground glass that allows the opposite side to be seen through.
Even in a translucent resin, if the translucency is such that the other side of the resin can be seen through, the light diffusion effect is diminished, and dazzling occurs during use.

  FIG. 5 is a perspective view of the clip portion 10 as seen from the back side. The clip part 10 is fitted or screwed to the light diffusion part by the light diffusion part fixing hole 42. The wiring embedding groove 37 is a groove for embedding a wiring from the LED built in the light diffusion portion 1 to the LED driving circuit so as not to stand out. The heat radiating plate 13 is used as a lid of the clip internal space 6 in order to release heat of the electronic components for LED driving.

  FIG. 6 is an exploded perspective view of the clip portion viewed from the side. The LED control circuit, the switch, and the AC adapter socket are compactly arranged so as to fit in the internal space 6 of the fixed clip portion 11.

  FIG. 7 is a cross-sectional view of the luminaire A and A cross-section in which the means for attaching the detachable luminaire to the mirror is changed from the clip to the suction cup 17. By attaching at least one suction cup 17 and a plurality of suction cups 17, the adhesion stability with the mirror 21 increases. If the thin and small suction cups are used in several places, the distance between the mirror 21 and the annular light diffusing unit 1 is reduced, and illumination can be performed more effectively. Further, since the suction cup can be attracted to any position on the mirror surface, for example, the center of the mirror, it can be used for a mirror display.

  FIG. 8 is a cross-sectional view showing a state in which the means for attaching to the mirror is an adhesive tape in the A and A cross sections of the lighting fixture. The adhesive stability with the mirror 21 is increased by attaching at least one adhesive tape 18 and a plurality of adhesive tapes 18. This is a method of attaching to the mirror almost permanently.

  FIG. 9 shows that the means for attaching to the mirror is hook-like in the A and A cross sections of the luminaire. This can be easily attached and detached by simply hooking the hook 19 on the edge of the mirror. It is also possible to sandwich the mirror by giving elasticity to the hook-like place.

The front-side surface of the light diffusing part 1 has a ground glass shape, or the light diffusing part 1 itself is made of a translucent resin. The light emitted from the LED 5 is diffused at a wide angle in the concave lens-shaped depression or the concave lens-shaped groove 2 and further diffused on the ground glass surface of one surface. Even if the light diffusing part 1 itself is a translucent resin, a similar diffusing effect can be obtained. However, due to the thickness of the translucent light diffusing part 1, the light arrival efficiency is lowered and becomes somewhat dark. The concave lens-like depression or concave lens-like groove is preferably mirror-finished in order to refract light well.
The material that diffuses and mixes the light is not limited to the ground glass surface, but can also be used to diffuse light such as a milky white plate or a translucent film. Is somewhat inferior in light transmission efficiency, and in the case of a translucent film, the diffusion effect is somewhat inferior.

In the present invention, the LED is driven from the AC power source through the LED drive circuit 36 in order to increase the brightness.
The LED and the LED driving circuit are desirably provided as close to each other as the light emission efficiency decreases as the distance between them increases. Here, a DC power supply is supplied to the power plug 14 using an AC pack power supply from an AC power supply.

In order to make the face look beautiful, for example, when taking a beautiful photo portrait, a little light from below is used. This helps to correct the dents and skeleton of the eye and make it softer.
This is the reason why the annular surface emitting part surrounding the mirror was used this time. The wide ring-shaped publishing surface also provides light from below to envelop the face, allowing you to project the most beautiful figure onto the mirror, just like when you take a portrait photo.
Of course, the same effect can be obtained not only in a ring shape but also in a square frame-shaped light emitting surface if it is a ring-shaped surface light source.

    For mirrors with other LED illumination devices, the simplest structure for LED light is to irradiate LED light directly, but because it is close to a point light source, the pupil closes due to glare. On the contrary, the face looks dark. The present invention contemplates that the light emitting surface can be as uniform as possible. A white LED is used as the light source LED, but a high color rendering white light LED made by mixing three primary colors is most desirable.
