As shown in FIG. 2, the outer cover 210 on the outer side of the front cover member 200 is made of a design member, while the inner cover 220 on the inner side is made of a light transmissive diffusing member. The upper portion 221 (see FIG. 1) of the inner cover 220 is uniformly illuminated by the inner LED (Light Emitting Diode) light, and a light shielding film is attached to the lower portion 222 (see FIG. 1) from the inside. Thus, the light that affects the projection screen is shielded (see FIG. 2A). More specifically, the inner cover 220 and the light shielding sheet 223 are fixed while being sandwiched between the outer cover 210 and the exhaust duct 230, and the inner cover 220 and the light shielding sheet 223 are fixed to the outer cover 210 and the wall surface. It is fixed in a state of being sandwiched between the metal fittings 240 (see FIG. 2B). In the assembled state, the fixing bracket 240 is attached to a bracket body (wall mounting bracket) which will be described in detail later (see FIG. 2C).

As is apparent from FIGS. 2 and 3, in this wall-mounted lighting fixture, the front cover member has a three-layer configuration in which the material is changed between the inner cover 220 and the outer cover 210, thereby providing a light feeling. Produces a sense of luxury. In addition, the double step structure provided by the outer cover 210 and the inner cover 220 achieves both functionality (exhaust heat) at the step portion and design. A top cover 250 and a bottom cover 260 are attached to the upper and lower sides of the outer cover 210 and the inner cover 220.

Subsequently, each of the above-described components incorporated in the front cover member 200 of the wall-mounted lighting fixture 100 will be described below.

<Projector device>
FIGS. 5A and 5B are perspective views showing the appearance of the projector device 300 having a function of projecting the image PI below the lighting fixture 100 from different angles. In these drawings, the projector device is shown. Reference numeral 300 denotes a lower case 2 having a substantially rectangular outer shape in which a main body is integrally formed with a bottom surface and surrounding four side surfaces (details will be described later), and an upper case 3 attached to the upper surface. It is comprised by.

As is clear from these drawings, the substantially central portion of the upper case 3 that is the upper surface of the projector device 300 is formed to rise in a hill shape (convex portion), and a part of the upper and lower mirror cover 31 is formed in a part thereof. Is cut off from other parts and attached so as to be rotatable by a predetermined angle toward the outside. In addition, a reflection mirror (free curved mirror) 32 that is a part of the optical system and is formed in a rotationally asymmetric shape is attached to the inside of the openable mirror cover 31. In addition, a lens optical system (see FIG. 6) not shown here is mainly disposed inside the convex portion of the cover portion 3 described above, and an opening 35 for guiding the projection light to the outside. (See FIG. 4. Note that in FIG. 5, only the last part of the lens optical system is shown through the opening 35). Further, on the surface of the upper case 3, a rotary knob 33 for focus adjustment, a touch panel type operation unit 34 including various input push buttons, and the like are respectively attached.

In particular, as is apparent from FIG. 5 (b), the projector device has one side surface of the lower case 2 having a substantially rectangular outer shape (the side surface opposite to the side on which the openable mirror cover 31 is provided). ) Is attached with a pair of stand legs 5 formed integrally with the main body so that the projector apparatus can be installed corresponding to the usage pattern of the projector device. In addition, on the other side surface of the lower case 2, as will be described later, the power inlet portion 6 into which a power cable is inserted, for example, when supplying AC power from a commercial power source to the device, The suction port 7 ′ and the exhaust port 7 which are openings for sucking and exhausting air to be performed to the outside, and although not shown here, an image projected and displayed by the projector device 300 is input from the outside. A terminal board or the like is attached. Further, although not shown, a cooling air intake / exhaust port, and an inclination adjusting leg for adjusting the installation angle of the device may be attached to the bottom surface of the lower case 2. In addition, although not shown here, a means (screw hole in this example) for attaching the fixing portion 520 of the wall mounting member 500 described below is formed on the bottom surface of the lower case 2 (hereinafter referred to as a screw hole). (See FIG. 7).

In addition, the external dimensions of the projector apparatus described above are not limited thereto, but as an example, width = W, depth = D, and height = H indicated by arrows in FIG. 5 are W = 265 mm and D = 200 mm, respectively. , H = 70 mm, the dimension corresponding to the so-called A4 size. The weight of the entire apparatus is set to be relatively light, about 1.2 kg. That is, it is possible to project the image light with a reduced trapezoidal distortion even from an extremely short distance (large tilt angle) with respect to the wall surface so that the image can be easily installed and projected. A projector device provided with a projection optical system having an ultrashort focal point including a so-called free-form surface mirror and a free-form surface lens, which can obtain an excellent projection image is preferable.

FIG. 6 is a cross-sectional view showing an example of the configuration of the optical system described above. For example, light from a light source such as a semiconductor laser (not shown here) is used in accordance with an external video signal (for example, a video signal from a portable terminal), for example, a DLP (Digital Light Processing) (registered trademark) device or the like. Modulation is performed by a reflection type light modulation device 301 including a micromirror or a reflection type liquid crystal panel (LCOS (registered trademark): Liquid crystal on silicon) or a liquid crystal panel. The image obtained thereby is synthesized by the TIR prism 302, projected onto the reflection mirror 32 via the projection lens system 303 comprising a plurality of lenses, reflected on the surface thereof, and projected in an enlarged manner. Note that the projection lens system 303 composed of the plurality of lenses described above is a free-form surface that is not rotationally symmetric and is necessary for correcting various distortions associated with enlarged projection of an image, such as distortion due to oblique incidence and trapezoidal distortion. Various types of lenses are included, including shaped lenses. The projection lens system 303 is movably mounted on the projection lens base 304, and moves a part of the projection lens or the lens group in the vertical direction in the figure by the action of the lens adjustment mechanism 305 in the figure. This makes it possible to adjust the focus performance.

Moreover, in this figure, it expands by the optical system mentioned above, is projected on the reflective mirror 32, and is reflected on the surface after that, for example, is projected on projection surfaces, such as a screen, a wall surface, a desk, a table, The upper limit light LU and the lower limit light LD of the image light are indicated by arrows in the drawing.

In addition, the projector device described above projects an image toward the wall surface (screen) which is a vertical surface inside the front cover member 200, and the front suction port is close to the vertical surface, while the rear The discharge port is disposed so as to be separated from the vertical surface. According to such an arrangement, the outside air sucked into the device along the wall surface which is a vertical surface is heated inside the device and then discharged from the discharge port separated from the wall surface. Through the opening 224 provided in the inner cover 220 of the member 200, it hits the inner wall of the outer cover 210, and as shown by the arrow in FIG. Therefore, the intake air and the exhaust gas do not mix to form a circulation flow, and efficient cooling is possible. In addition, since the projector device 300 projects an image on the lower side of the front cover member 200, it is preferable that the exhaust be emitted upward.

That is, by rotating the adjustment dial (3) 90 shown in FIG. 15A, the projector device 300 is moved within the movement range shown in FIG. 15B, that is, centered on the Y axis in the figure. Adjustment in the direction of rotation is possible. In particular, since the hemispherical bearing 523 is located in the vicinity of the emission from the projector device, the positional deviation of the projected image can be suppressed during adjustment around the X axis and the Y axis. In addition, since the change in the projection distance can be minimized during adjustment, the change in the projection size can be minimized.

Further, FIGS. 16 (a) and 16 (b) show, in particular, that only one of the adjustment dial (1) 70 and the adjustment dial (2) 80 is rotated, or both of them are rotated in directions opposite to each other. The adjustment in the rotation direction (indicated by an arrow in the figure) around the Z axis in the figure is shown. That is, by rotating the adjustment dial (1) 70 and / or the adjustment dial (2) 80 shown in FIG. 16A, the projector device 300 is moved within the movement range shown in FIG. That is, it is possible to adjust the rotation direction around the Z axis in the figure. Since the adjustment dials (1) 70 and (2) 80 are substantially equal to the left and right in the image projection direction with respect to the hemispherical bearing 523, the two adjustment dials can be used to adjust the X axis and the Y axis. Yes, and it is easy to grasp the necessary adjustment amount. In particular, the triangle formed by the three positions of the hemispherical bearing 523 and the

dials

70 and 80 includes the center of gravity of the projector device inside thereof, so that an excessive load is not applied to a part of the three positions, and adjustment work is not required. Smooth and easy.

FIG. 17 shows the relationship between the rotation axis that can be adjusted by the three adjustment dials described above and the tendency of the image distortion caused by the rotation axis. In the triaxial adjustment mechanism described above, triaxial adjustment is performed by appropriately rotating the adjustment dials (1) 70, (2) 80, and (3) 90 shown in FIG. However, the amount of movement in the axial direction of the dial depends on the pitch of the screw groove, and in order to perform finer position adjustment, especially if the pitch of the screw (screwing) groove formed on the surface of the adjustment dial is made finer. Good. For example, although the pitch of the M3 metric coarse screw is 0.5 mm, the pitch of the fine screw is 0.35 mm, and the amount of movement per rotation can be reduced. Further, by increasing the diameter of the adjustment dial operation unit (see reference numeral 73 in FIG. 12), the amount of movement of the operation unit per one rotation can be increased. For example, when the operation unit is turned by hand The amount of movement in the axial direction is smaller than the amount of movement, and fine adjustment is easier.

As described in detail above, according to the mounting member 500 described above, the projector fixing bracket 520 fixed to the projector device 300 can be adjusted in the three-axis direction using the hemispherical shaft 512 and the hemispherical bearing 523. With this configuration, the wall fixing bracket (three-axis adjusting bracket) 510 attached to the wall surface can be adjusted by rotating and moving. Therefore, when the wall fixing bracket (three-axis adjustment bracket) 510 attached to the wall surface is mounted out of the original mounting position (for example, slightly inclined with respect to the vertical direction or horizontal direction of the wall surface). In addition, when the projection apparatus 300 is tilted due to an external force such as an earthquake or a human contact and the projection screen is distorted, the projection screen is distorted again by adjusting in the three axis directions with the adjustment dial. Can be easily corrected.

In the above example, the three adjustment dials are described as being attached to a part of the triaxial adjustment fitting 510 attached to the wall hanging bracket 400. However, the present invention is not limited to this, and the adjustment dial is not limited thereto. Are reduced to two (for example, the adjustment dial (1) 70 or (2) 80 and the adjustment dial (3) 90), or these adjustment dials are not the three-axis adjustment fitting 510 but the projector. It will be obvious to those skilled in the art that the same effect can be obtained even if the fixing bracket 520 is attached.

In the above-described embodiment, the hemispherical shaft / bearing is used as the means for rotatably connecting the projector fixing bracket 520 to the triaxial adjusting bracket 510. However, the present invention is not limited thereto. However, the present invention is not limited to such an embodiment. For example, a spherical shaft / bearing or other mechanism may be used as long as it can freely rotate.

<Lighting device>
Subsequently, in the above-described PJ-integrated wall-mounted lighting fixture 100, illumination light is generated to achieve the illumination light IL attached to the inside of the above-described front cover member 200 and having a soft and soft light distribution distribution above it. The illuminating device 600 which is a part will be described in detail below.

As shown in FIG. 2 described above, the lighting device 600 is configured by combining two plate-like LED substrate assemblies 610 shown in FIG. 18 below in a substantially “V” shape. The LED substrate 620 includes a substrate on which light emitting diodes as a plurality of light emitting sources are arranged in a row, and the LED cover 630 is formed of a light transmissive member. The LED substrate 620 and the LED cover 630 are fixed to a fixture 640 that also serves as a heat sink. The LED board assembly 610 is attached to the bracket body (the three-axis adjusting bracket 510 which is a constituent part of the projector fixing bracket 500) in an assembled state having an outer shape of approximately “V”.

According to the illuminating device 600 having the above-described configuration, the LED substrate assembly 610 is arranged in a “V” shape with respect to the semicircular inner cover 220, so that light from the light emitting diodes of the LED substrate assembly 610 is emitted. As shown by the arrows in FIG. 19, the illumination light IL with a light and gentle light distribution is achieved by uniformly illuminating the surface of the inner cover 220 made of a light transmitting material. Further, a part of the reflected light on the inner surface of the inner cover 220 functions as indirect illumination by illuminating the rear (wall side). In addition, by adjusting and optimizing the positional relationship such as the distance and angle between the inner cover 220 and the LED board assembly 610, it is possible to reproduce uniform and brilliant illumination light, an example of which is shown in FIG. Show. Further, since both the top cover 250 and the inner cover 220 are light transmitting members, various color rendering properties can be imparted by adjusting the surface treatment and color tone, and the top cover 250 also functions as a dust-proof measure. ing. In addition, it is preferable to set the distance between the inner cover 220 and the LED board assembly 610 so that the viewer of the lighting fixture is not aware of the point light source formed of the light emitting diode. The inner cover 220 and the top cover 250 are formed of a translucent member such as frosted glass that diffuses light.

As a result, as shown also in FIG. 20, the light from each light emitting diode of the LED board assembly 610 strikes the upper part of the inner cover 220 constituting the front cover member 200, and is reflected and scattered there, whereby the luminaire From the upper part of 100, it becomes irradiation light which goes to the wall surface through the upper part of the inner cover 220 or the top cover 250, and generates indirect illumination light IL having a soft and soft light distribution.

Further, as is clear from FIG. 21, a bottom cover 260 formed of an opaque light-shielding member of the front cover member 200 is provided, whereby the illumination light from the LED board assembly 610 is emitted from the projector. The projected image from the apparatus is not adversely affected. On the other hand, the reflection of the projected image from the projector apparatus 300 on the wall surface does not adversely affect the illumination light. Further, by attaching a light shielding sheet 223 inside the inner cover 220, the reflection of the image light from the screen side is shielded, and the transmission of the image light to the front surface of the inner cover 220 is prevented. In other words, the PJ-integrated wall-mounted luminaire 100 of the present invention has the illumination light generator and the projector device integrated therein, but according to the above-described structure, they do not adversely affect each other. It is possible to achieve both the function as a lighting fixture and the function as a projector device in a suitable manner.

In addition, this invention is not limited to the above-mentioned Example, Various modifications are included. For example, the above-described embodiments are described in detail for the entire apparatus in order to easily understand the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
