Description

  The present invention relates to a lighting fixture attached to a ceiling, a wall, a pillar, or the like of a residence or a public building, and in particular, an auxiliary lighting function is added in addition to a light emitting lighting function, and this auxiliary lighting function is used to provide a decorative property. It is related with the set lighting equipment.

  In conventional lighting fixtures, for example, ceiling-mounted lighting fixtures, in addition to the original light-emitting illumination functions such as fluorescent lamps, incandescent lamps, halogen lamps, etc., various contrivances have been made in consideration of decorativeness by light. That is, by controlling the lighting circuit and the combination of fluorescent lamps, incandescent lamps, halogen lamps, etc., which are light sources for illumination, these light sources are made bright and dark, or indirect light by reflected light from the light sources is used. The design on the exterior was created to give a decorative effect.

  In addition, a light emitting diode is added as a new light source to an illumination light source such as a fluorescent lamp, an incandescent lamp, a halogen lamp, etc., and these are combined and arranged in the luminaire body. And the lighting fixture which enabled it to switch illumination light sources, such as a lamp | ramp, and a light emitting diode and to adjust illumination intensity is proposed (for example, refer patent document 1).

  As another example of a luminaire equipped with a light-emitting diode, a light-emitting diode is incorporated as a light source for auxiliary lighting in a shade that covers an illumination light source such as a fluorescent lamp so as to bring about a decorative effect that cannot be obtained by a simple shade alone. Lighting fixtures have also been proposed (see, for example, Patent Document 2).

  However, in the conventional lighting fixtures, particularly those having a structure in which an incandescent lamp or a halogen lamp is incorporated, it is necessary to take measures to increase power consumption and to generate heat, so that the size of the lamp built-in fixture is increased. As a result, it is necessary to secure a space for installation in the lighting fixture, and the structural design and appearance design of the entire lighting fixture are restricted. Further, only light sources such as fluorescent lamps, incandescent lamps, halogen lamps, etc. simply display light and dark, and the decorativeness is poor.

  In addition, if the light emitting diode is used as a light source for illumination, a large number of light emitting diodes must be incorporated, and there is a problem that the entire lighting fixture is accordingly increased in size.

  In addition, when it is attempted to obtain decoration by incorporating a light emitting diode into the shade, there is a problem that the structure of the shade becomes complicated and the design and manufacturing costs increase.

  The present invention has been made to solve the above-mentioned problems, and is small in size, reduces the amount of electric power and heat generation, and reduces the design (appearance) and restrictions on the design and manufacture of the structure of the lighting fixture. Provided is a lighting apparatus capable of obtaining an excellent shape. It is another object of the present invention to provide a luminaire that can improve decorativeness by enabling not only light and dark but also color change and various light emission shapes.

  The luminaire of the present invention includes a luminaire main body having a fluorescent lamp and a lighting circuit, a light emitting diode built-in unit that includes a plurality of light emitting diodes and is mounted around the luminaire main body, and is mounted on the luminaire main body. A cover for covering the fluorescent lamp, and the cover is provided with a plurality of light-emitting decorations that receive the light from the light-emitting diodes and emit decorative light.

  The light emitting diode according to the present invention is attached to the light emitting diode built-in unit so as to emit light in a direction perpendicular or parallel to a mounting surface of the lighting fixture body, and the plurality of light emitting diodes are 1 It is characterized by using a plurality of types of luminescent colors or a combination of a plurality of types of luminescent colors, and when the cover is put on the luminaire body, a plurality of the light emitting diodes and a plurality of the light emitting decorations The positions are close to each other and correspond to each other on a one-to-one basis, and light from the light emitting diodes is irradiated onto the end face of the light emitting decoration.

  The light emitting decoration according to the present invention is made of a translucent material made of a solid or hollow bar. The hollow bar has a structure in which both ends are opened or one end is opened and the other end is closed. Alternatively, the hollow bar has a structure in which one end is opened and a lens is fitted to the other end. Further, fine grooves or fine irregularities are formed on the outer surface or hollow inner surface of the solid or hollow bar.

  Further, the lighting circuit provided in the lighting fixture body according to the present invention is configured to perform control to turn on or turn off the fluorescent lamp and the light emitting diode, and turn off or reduce the fluorescent lamp. In some cases, the light emitting diode is used as auxiliary illumination in place of the fluorescent lamp as the main illumination.

  According to the present invention, a luminaire with excellent decorativeness can be obtained by irradiating light emitted from a light emitting diode, which is merely a point light source by itself, onto a light emitting decoration attached to a cover. Also, by controlling the lighting circuit built into the fixture body, not only can the main lighting be made brighter and darker, but also the light color of the light-emitting diode, which is auxiliary lighting, can be changed, such as changing the indoor atmosphere. An excellent lighting fixture can be obtained.

As shown in FIGS. 1 and 2, in the basic structure of the lighting fixture of the present invention, a lamp 2 (round fluorescent lamp) is attached to a fixture body 1 having a lighting circuit 12 and a reflector 13. A cover 3 (glove or shade) is attached to cover the lamp 2. A light emitting diode built-in unit 4 formed in a ring shape so as to surround the instrument body 1 is attached to the instrument body 1. Around the light emitting diode built-in unit 4, several (in this embodiment, four) light emitting diodes 5 are installed. Then, four light emitting diodes 5 are installed with the light emitting direction facing downward at positions that are equally divided into four surroundings.

The cover 3 is formed of a translucent resin and is attached via a cover attachment 7 provided on the instrument body 1 so as to cover the entire lower surface of the instrument body 1. Further, on the outer peripheral surface of the cover 3, cylindrical or round bar-shaped light emitting decorations 6 are vertically attached with screws or the like at four positions in accordance with the positions of the light emitting diodes 5 installed in the light emitting diode built-in unit 4. .
Since the light emitting decoration 6 is detachably attached by screws or the like, it can be exchanged for a favorite one by preparing various shapes in advance.

  In addition, a lighting circuit 12 is incorporated in the fixture body 1, and a reflection plate 13 is attached so as to cover the lighting circuit 12. A light emitting diode power supply cord 8 for supplying power to the light emitting diode 5 is drawn out from the lighting circuit 12.

  When the lighting fixture configured in this way is attached to a ceiling or the like, as shown in FIG. 3, the fixture main body 1 and the light emitting diode built-in unit 4 are first integrated with a light-emitting diode built-in unit mounting screw 9. The integrated unit is attached and fixed to the ceiling 14 by the fixture body fixture 11 via the wiring fixture 15 fixed to the ceiling 14, and at the same time, electrical connection is made. Then, the lamp 2 is mounted on the lamp socket 10 attached to the reflecting plate 13 and finally the cover 3 is covered. At this time, the light-emitting diode 5 and the light-emitting decoration 6 are aligned so as to correspond one-to-one.

  Moreover, the cover 3 attached to the lower surface of the instrument main body 1 has various shapes so as to cover the lamp 2 which is the main illumination, and is easily fitted to the cover fixture 7 attached to the instrument main body 1. The lighting circuit 12 is a device that controls the lamp 2 and the light-emitting diode 5, which are main lights, to be turned on, turned off, reduced, and blinking. The lighting circuit 12 is covered with a reflecting plate 13, and a lamp 2 that is main illumination is disposed below the reflecting plate 13.

  In addition, a light emitting diode built-in unit 4 equipped with four light emitting diodes 5 is fixed to the fixture body 1 by light emitting diode built-in unit mounting screws 9. The four light emitting diodes 5 are connected to a lighting circuit 12 incorporated in the appliance body 1 and are controlled to be turned on and off. The light emitting diode 5 serves as an auxiliary illumination function for the main illumination.

  Next, the decorativeness which the lighting fixture of this invention has is demonstrated using FIG. FIG. 4 is a view showing the appearance and a partial cross section of the lighting apparatus according to the first embodiment of the present invention. FIG. 4 (a) is a perspective view of the lighting apparatus, and FIGS. It is sectional drawing which shows Example 1, 2, 3 in the A section of FIG.

  In FIG. 4A, the light emitting diode 5 incorporated in the light emitting diode incorporating unit 4 is provided so as to emit light in a direction perpendicular to the ceiling surface to which the lighting fixture is attached. The light emitted from the light-emitting diode 5 is incident on a light-emitting decoration 6 attached to the cover 3, and lighting fixtures having various decorative properties are completed depending on the shape (finish) of the light-emitting decoration 6.

  The light emitting decoration 6 of Example 1 shown in FIG. 4B is a transparent or translucent solid round bar made of resin or glass, for example, having a diameter of about 1 cm and a length of about 5 cm. The upper end surface facing the light-emitting diode 5 is formed into a flat surface or a spherical surface, and is polished to make it easier for the spot light from the light-emitting diode 5 to enter. On the other hand, a rough surface is formed on the lower end surface portion in order to diffusely reflect the spot light that has traveled straight or totally reflected in the light emitting decoration 6. At the same time, knurled fine grooves are also processed on the side of the round bar near the lower end.

  As a result, light is scattered at the lower end, and light emission toward the lower surface of the light emitting decoration 6 becomes possible. Further, by changing the surface finish processing state, luminescent decorations having various luminescent shapes can be obtained. Also, by changing the color of the light emitting diodes or combining light emitting diodes of different colors, light emitting decorations having various color changes can be obtained.

  Next, Example 2 in FIG. 4C will be described. In this embodiment, a cylindrical light emitting decoration 6 is used. A lens 16 is fitted into the lower end of the cylinder, and the spot light from the light emitting diode 5 reaches the lens 16 through the hollow portion of the light emitting decoration 6, and is enlarged by the lens 16 to emit light downward. ing.

  Next, Example 3 of FIG. 4D will be described. In this embodiment, a cylindrical light emitting decoration 6 is used. The lower end of the cylinder is sealed, and fine grooves or rough surfaces are formed on the inner surface and the bottom surface. Light from the light emitting diode 5 (not shown) installed above the light emitting decoration 6 is reflected from the inside of the cylinder or the inner bottom surface and travels toward the top surface. The light emitted in the upper surface direction can illuminate the ceiling surface as indirect illumination.

  FIG. 5 is a view showing a second embodiment of the present invention, and is a view for explaining a light emitting decoration when the light emitting direction of the light emitting diode is parallel to the ceiling surface. FIG. 5A is a cross-sectional view of the lighting fixture showing the fourth embodiment, and FIG. 5B is a partial cross-sectional view of the lighting fixture showing the fifth embodiment.

  In the present embodiment, the direction of the light-emitting diode 5 attached to the light-emitting diode built-in unit 4 is set so that the light-emitting direction of the light-emitting diode 5 is parallel to the ceiling surface. The light is emitted along the surface.

  Example 4 is a case where the light emitting diode 5 is functioned independently without using a light emitting decoration as shown in FIG. Further, in Example 5, a block-like light emitting decoration 6 is attached to the cover 3 as shown in FIG. 5B, an opening is provided at a position corresponding to the light emitting diode 5, a lens 16 is installed in the opening, and the light emitting diode 5 I try to expand the light from. Further, as the shape of the light emitting decoration 6, a round bar shape or a cylindrical shape may be installed horizontally as shown in FIG.

  As described above, the present invention has been described based on the embodiment. However, although the light emitting diode can be controlled to blink by the lighting circuit, the light emitting diode is only a point light source. Therefore, by irradiating the light emitting decoration with the light from the light emitting diode, the spot light can be diffused or expanded, and a lighting fixture having excellent decorativeness can be obtained. Further, the indoor atmosphere can be changed by dimming the main illumination and changing the color of the light emitted from the light emitting diode which is the auxiliary illumination.

  Further, the number of light emitting diodes is not limited to four, and may be any number. The light emission color is not limited to one color, and any of R, G, and B, or a combination thereof may be used. Further, the light emitting decoration is not limited to a round bar but may be a square bar. Furthermore, since the luminescent ornament is detachably attached, it can be exchanged, and various shapes can be used in any combination.

  Further, the lighting circuit may be controlled by switching the light emitting diodes on at the same time as turning off the main illumination by using the pull switch as it is. It is also possible to switch between main lighting and auxiliary lighting by remote control, or to control the display so as to exhibit decorativeness suitable for the place by appropriately combining the color and number of light emitting diodes.

  Further, in the present embodiment, the lighting fixture directly attached to the ceiling has been described as an example. However, the lighting fixture may be directly attached to a wall or a pillar or the like, and may be applied to a hanging type lighting fixture. Of course.

  According to the lighting apparatus of the present invention, not only for use in ordinary homes, but also in public facilities or stores, etc., decorativeness is improved by enabling not only mere brightness but also color change and various light emission shapes. A great effect can be obtained.
