DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture.

[0002]

2. Description of the Related Art Conventionally, when a person sleeping indoors at night tries to check the time, he or she has checked by looking at a bedside clock or a clock on a wall.

[0003]

However, since it is nighttime, the interior of the room is dark or there is only a weak light of the nightlight of the lighting equipment. It was not easy to confirm. In particular, when the sleeping person is a person with weak visual acuity, it is more difficult because the eyeglasses and the like are removed.

[0004] Also, there is an alarm clock in which a lighting device is incorporated in a dial, but since it is necessary to perform lighting operation by using a button or the like, it is difficult for a sleeper to search for a clock at a bedside and perform the operation. Was troublesome. The present invention has been made to solve the above problems.

To solve the above problem.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1A is a side view of the lighting fixture according to the embodiment of the present invention, and FIG.
Is a bottom view of the same. FIG. 2 is an explanatory diagram of the internal structure of the lighting fixture, and FIG. 3 is an explanatory diagram of a clock display projection mechanism.

A lighting fixture 1 according to an embodiment of the present invention.
Is a luminaire in which a luminous body such as a fluorescent lamp 11 is housed. A translucent translucent body 2 made of, for example, plastic and subjected to a three-dimensional processing such as a disk is used as a cover of the entire luminaire. It is provided at least below a luminous body such as the fluorescent lamp 11. Inside the lighting fixture 1, lenses 4, 4a and reflecting mirrors 5, 5a are fixed.
The clock display projection image 6 enlarged by a can be projected on the light transmitting body 2. That is, a projection mechanism including the light source 8 for projection, the watch main body 3, the lenses 4, 4a, and the reflecting mirrors 5, 5a is arranged inside the lighting fixture 1.

In this example, as shown in FIG. 2, the luminaire 1 is of a ceiling-mounted type having two fluorescent lamps 11 and 11, and a power supply unit and a mounting mechanism are provided in the center of a main body 12. Provided with an adapter 13 provided near the outer periphery thereof.
Lighting circuit board 14, night light bulb 15, power switch 1
6 is provided. A frame composed of an inner frame 18 and an outer frame 19 is detachably attached to the outer peripheral portion 17 of the casing of the main body 12, and the outer periphery of the light transmitting body 2 is fixed between the inner frame 18 and the outer frame 19. ing. A reflector 20 is arranged on the lower surface side of the main body, and the lighting circuit board 14, the power switch 16, and the like are housed inside the reflector 20. Then, a projection mechanism 10 is provided below the reflection plate 20 via a mounting bracket 9.
Is attached.

As the light source 8 for projection, a small light bulb is used. The required illuminance is determined when the light emitter such as the fluorescent lamp 11 is turned off.
It is sufficient that the clock display projected image 6 can be projected on the translucent body 2. In this example, a light source different from the nightlight bulb 15 is used, but the nightlight bulb 15 may be used as it is. The projection light source 8 can be switched on and off freely so that the clock display projection image 6 can be turned off when it is not necessary. When the light source 8 is also used as a nightlight, the clock display projection image 6 is always projected on the translucent body 2 when the nightlight is lit. The power source of the light source 8 may be a power source for the entire lighting fixture 1 such as a fluorescent lamp, or a separate DC power source such as a dry cell.

The watch main body 3 is composed of a hand driving unit 3a, a dial 3b and a hand 3c when an analog display is projected. As the pointer driving unit 3a, the one used in a normal wall clock or the like may be used as it is. In this example, the clock may be the same as a normal wall clock, but when the projected image of the clock display becomes an inverted image due to the lens configuration, it is necessary to have a structure that rotates in the reverse direction. In this example, dial 3
b is integrated with a reflecting mirror 5a to be described later, and a character or a pattern to be projected directly on the translucent member 2 is arranged on the reflecting mirror 5a. The hands 3c are arranged so as to rotate on the dial 3b. The hands 3c and the character display on the dial 3b use an opaque material and project a shadow thereof or a colored image by using a colored translucent material. The pointer driving unit 3a is arranged so as not to come to the front side of the reflecting mirror 5a. A portion that does not require projection, such as the periphery of the dial 3b, may be previously blackened so as not to reflect light or transmit light. Although not shown, the dial 3b and the reflecting mirror 5a can be separated from each other. In this case, the translucent dial 3b is arranged on the reflecting mirror 5a, and the dial 3b is arranged. Arrange characters and patterns on 3b. The hands 3c are positioned on the front side of the dial 3b,
Alternatively, it is arranged on the back side of the dial 3b (that is, between the reflecting mirror 5a and the dial 3b).

As another method, a light-emitting body such as an LED is embedded in the dial 3b or the hands 3c, or the display of the main body of the watch is digitally displayed by a light-emitting body such as an LED, so that the above-mentioned light emitting light source 8 is omitted. There is also a way to do this. By doing so, the number of components related to the projection of the clock display projection image 6 can be reduced.

The lenses 4 and 4a are convex lenses formed of glass or transparent plastic and have a function of enlarging the clock display projected image 6. The principle of the enlargement is shown in FIG. 4, and the image 3 of the object 30 placed near the lens 40 is shown in FIG.
0a is magnified and projected on the opposite side of the lens. As the lenses 4 and 4a, lenses having an optimum focal length according to the distances of the watch body 3, the reflecting mirrors 5 and 5a, and the light transmitting body 2 are applied. Although a lens having a shorter focal length can form a projection mechanism more compactly, the influence of spherical aberration is greater and the peripheral portion of the clock display projected image 6 is particularly easily distorted. The clock display projected image 6 is enlarged by using two lenses. As another method, a method of eliminating spherical aberration by using one aspherical lens can be considered.

The reflecting mirrors 5 and 5a are used to bend the optical path and compactly store the components inside the lighting apparatus 1, and use a plane mirror. Alternatively,
A concave mirror may be used as the reflecting mirror to provide a function of enlarging the projected image, and the lens 4 may be omitted.

FIG. 3 shows an example of the positional relationship of the respective components for projecting the clock display projected image 6. In this example, the light source 8 for light projection, two reflecting mirrors 5 and 5a, the watch main body 3 (the reflecting mirror 5a and the watch main body 3 are also used in this example),
By arranging the lenses 4 and 4a in this order, an inverted virtual image of the watch main body 3 is formed on the translucent body 2 arranged below by the light projecting light source 8 arranged laterally. In addition,
The inverted virtual image projected on the light transmitting body 2 is in an inverted state when viewed from the inside of the light transmitting body 2, and is in an upright state when viewed from the outside of the light transmitting body 2. The clock main body 3 can be a normal clock.

The translucent member 2 is formed by shaping a translucent plastic plate or the like into an arbitrary shape, and a clock display projection image 6 is projected inside the translucent member 2. When the projection plane is flat, as shown in FIG. 5, as the distance from the optical axis A increases due to the spherical aberration of the lens 4a, the flat plane virtual plane screen X and the imaging plane Y move away from each other. Therefore, the periphery of the clock display projection image 6 is distorted. Therefore, it is desirable that the projection surface portion of the light transmitting body 2 is formed into a curved surface shape that matches the image forming plane Y so that each part of the clock display projected image 6 is focused on each surface of the light transmitting body 2. In FIG. 5, A indicates an optical axis, f indicates a focus, X indicates a virtual plane screen, and Y indicates an image plane.

The positional relationship between the components can be arbitrarily changed depending on the layout of the components in the lighting fixture 1. For example, the present invention is implemented without using a reflecting mirror or using only one sheet. Alternatively, more reflectors may be used. In addition, one or a plurality of reflecting mirrors are arranged between the lens and the translucent member so as to increase the optical distance between the lens and the translucent member so that a larger clock display projected image 6 can be obtained.
May be projected. The clock display projected image 6 can be made larger when the position of the watch main body 3 is as close as possible to the focal point of the lens 4.

In addition to the above embodiments, the present invention provides
Various modifications can be made. For example, a part of the light transmitting body 2 may be formed in a transparent window shape, and the inside of the clock display 6 may be directly viewed through the viewing window. In this case, no lens is provided or a lens having a long focal length is used.

In addition, as shown in FIG. 6, only one lens 4b having a relatively short focal length is used without using a reflecting mirror, and a clock display projected image 6 is used without reflecting and bending the optical path.
Is projected on the translucent member 2 in an enlarged manner. In this case, the number of components can be reduced, but it is necessary to devise the shape of the light transmitting body 2 in consideration of the influence of the spherical aberration of the lens 4b described above. The example of FIG. 6 shows a dial 3 capable of transmitting light from an adapter 13 having a power supply device and an attachment mechanism.
b is hung, and a lens 4b
The night light bulb 15 provided on the adapter 13 is used as the light source 8 for projection, and a real image of the timepiece body 3 located thereunder is arranged below the lens 4b. To be connected to the light transmitting body 2.

As shown in FIG. 7, the projection mechanism utilizes the diffusion of light from the light source 8 for projection without using a lens between the body of the timepiece and the translucent body. Can also. That is, the watch main body 3 is arranged below the light source 8 for light projection, and the translucent body 2 located below the watch main body 3 is arranged.
Is projected on the inner surface of the watch body 3 by the light source 8 for light transmission. More specifically, the timepiece main body 3 inside the lighting fixture includes a drive unit 3a, a dial 3b, and gears 3c, 3c. The dial 3b is formed of a transparent plate, and the short hand and the long hand are drawn and formed on transparent gears 3c, 3c, respectively. The dial 3b is arranged between the light source 8 for light projection arranged inside the lighting fixture and the translucent member 2 so that the gears 3c, 3c can rotate with respect to the dial 3b.
It is pivoted. The drive unit 3a of the timepiece is provided outside the dial 3b. The rotation of the drive unit 3a is transmitted to the gears 3c, 3c by meshing the gears, and the display of the short hand and the long hand is rotated. The display of the dial 3b and the gears 3c, 3c
The display of the upper hand and the longer hand is enlarged and projected on the inner surface of the light transmitting body 2 as a clock display projected image 6, and the clock display can be visually recognized from the outside of the light transmitting body 2. The driving unit 3
In order to prevent shadows such as a from being projected onto the translucent body 2, it is desirable that the periphery of the dial and the like be subjected to processing such as black coating so as not to transmit light. In addition, such a configuration, that is, a configuration in which the short hand and the long hand are displayed on the transparent plate, and a transparent plate in which the short hand and the long hand are displayed, by the teeth of the outer peripheral gears, etc. The configuration in which the driving mechanism is prevented from being projected onto the light transmitting body 2 by driving from the position can be applied to each of the above embodiments. still,
Also in this embodiment, a lens for enlarging an image can be used together.

It is also possible to add an alarm function to the clock body 3a and use it as an alarm clock.
In addition, a remote controller can be provided separately to operate each function. In addition, only watches with short and long hands are positioned inside the lighting fixture, while the dial is displayed directly on the inside or outside of the translucent body, and only the images of the short and long hands are projected on the translucent body. It may be.
