Description

  The present invention relates to a lighting apparatus using lamps having different emission colors.

  2. Description of the Related Art Conventionally, a lighting fixture using lamps having different emission colors has a configuration described in, for example, Japanese Patent Application Laid-Open No. 62-5599.

  In this lighting fixture, three annular fluorescent lamps of red, green, and blue are arranged concentrically on the lower surface of the appliance main body, and a light-diffusing shade that covers these annular fluorescent lamps is arranged.

Then, the three annular fluorescent lamps of red, green and blue are simultaneously turned on to uniformly mix the red, green and blue lights emitted from the three fluorescent lamps, and the mixed light illuminates through the shade. Like to do.
JP-A-62-2599

  However, in the conventional lighting fixtures, a plurality of annular fluorescent lamps having different emission colors are used, but the lights having different emission colors are mixed uniformly and illuminated with this mixed light, that is, The light color unevenness that the seed shines is prevented.

  Therefore, conventionally, when the lamps having different emission colors are simultaneously turned on, the light color in which the shade shines is actively changed to obtain the illumination effect.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a luminaire that is capable of obtaining a lighting effect by actively changing the color of light emitted by a shade when simultaneously lighting lamps having different emission colors.

  The lighting fixture according to claim 1 is a fixture main body: a plurality of lamps having two or more kinds of luminescent colors arranged in the fixture main body; and a light corresponding to between lamps arranged opposite to the plurality of lamps and having different luminescent colors. And a shade having a color boundary portion.

  With this configuration, when the lamps having different emission colors are turned on at the same time, the light color at which the shade shines is clearly changed with the light color boundary portion as a haze, thereby obtaining a high illumination effect.

  According to the luminaire of claim 1, since a shade having a light color boundary portion is opposed to a plurality of lamps having two or more kinds of emission colors corresponding to the lamps having different emission colors, When the lamps having different colors are turned on simultaneously, the light color at which the shade shines can be clearly changed with the light color boundary portion as the eaves, thereby obtaining a high illumination effect.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 and 2 show a first embodiment, FIG. 1 is a sectional view of a lighting fixture, and FIG. 2 is a bottom view of the lighting fixture.

  The lighting fixture is a ceiling-mounted lighting fixture in which three annular fluorescent lamps L1, L2, and L3 having different diameters (wattage) are used as lamps.

  Of the three annular fluorescent lamps L1, L2, and L3, the largest fluorescent lamp L1 has a light bulb color whose emission color is evaluated as a warm color having a correlated color temperature of about 3000K, for example. As the annular fluorescent lamps L2 and L3, those having a daylight white color whose emission color is evaluated as a natural color having a correlated color temperature of about 5000K, for example, are used. In addition to the light bulb color and daylight white, for example, there are daylight colors evaluated as cool colors having a correlated color temperature of about 6700K, and these may be combined as appropriate.

  The lighting fixture has a fixture main body 11 formed in a disc shape, and electrically and mechanically through an adapter to a hooking ceiling installed on the ceiling surface 12 (not shown) at the center of the fixture main body 11. A connecting portion to be connected is provided, and a conical reflecting plate 13 is attached to the lower surface.

  A holder 14 is mounted on the lower surface of the reflector 13 to support the three annular fluorescent lamps L1, L2, and L3 in a concentric manner, and is connected to the caps of the annular fluorescent lamps L1, L2, and L3. A socket (not shown) is attached.

  A lighting device 15 for lighting and controlling lighting of the three annular fluorescent lamps L1, L2, and L3 separately is disposed inside the reflecting plate 13. The lighting device 15 is configured by an inverter circuit or the like mounted on a printed circuit board, and is operated by a wall switch or a remote controller.

  A shade 16 that covers the three annular fluorescent lamps L1, L2, L3, the reflection plate 13, and the like is attached to the lower surface of the instrument body 11. The shade 16 is integrally formed of a translucent milky white resin material, and the shade surface portion 17 is formed in a curved shape that is gently curved, and the shade surface portion 17 has a ring-shaped fluorescent light having a different emission color. An annular light color boundary 18 is formed between the lamps L1 and L2.

  In the light color boundary portion 18, an annular convex portion 19 is integrally formed so as to project from the inner surface of the shade surface portion 17 between the annular fluorescent lamps L1 and L2, and the convex portion 19 opens to the outer surface of the shade surface portion 17. An annular groove 20 is formed. Only the tip, that is, the upper surface of the convex portion 19 is formed to be transparent.

  Next, the operation of the present embodiment will be described.

  The three annular fluorescent lamps L1, L2, and L3 are lit separately or simultaneously by the lighting device 15.

  When the three annular fluorescent lamps L1, L2, and L3 are turned on at the same time, the light emitted from each of the annular fluorescent lamps L1, L2, and L3 passes through the shade 16 to irradiate the interior of the room.

  At this time, with the light color boundary 18 as the ridge, the outer diameter side 16a of the shade 16 shines in a light bulb color corresponding to the emission color of the annular fluorescent lamp L1, and the center side 16b of the shade 16 emits light of the annular fluorescent lamps L2 and L3. It glows in neutral white corresponding to the color. Therefore, the light color that the shade 16 shines can be clearly changed with the light color boundary portion 18 as a trap, and thereby a high lighting effect can be obtained. In particular, since a circular or annular light-colored ring is concentrically formed on the shade 16, the lighting effect is high.

  Further, as the light color boundary portion 18, an opening is formed on the surface of the shade surface portion 17 by the convex portion 19 protruding from the inner surface of the shade surface portion 17 toward the annular fluorescent lamps L2 and L3, and the convex portion 19. Since the groove portion 20 is provided, the light color boundary of the shade 16 is generated in the groove portion 20, and the light color of the outer side 16a and the center side 16b of the shade 16 is clearly changed without using a special part. be able to.

  Moreover, by forming only the tip of the convex portion 19 of the milky white shade 16 transparently, the inside of the groove portion 20 is brightened, and the light color of the outer diameter side 16a and the central side 16b of the shade 16 is changed more clearly. Can be made.

  When only the annular fluorescent lamp L1 is turned on, the outer diameter side 16a of the shade 16 mainly shines in the light bulb color corresponding to the emission color of the annular fluorescent lamp L1.

  In addition, when one or both of the annular fluorescent lamps L2 and L3 are turned on, the central side 16b of the shade 16 mainly shines in neutral white corresponding to the emission color of the annular fluorescent lamps L2 and L3.

  Next, FIG. 3 to FIG. 5 show a second embodiment, FIG. 3 is a sectional view of the lighting fixture, FIG. 4 is a side view of the lighting fixture, and FIG. 5 is a bottom view of the lighting fixture.

  In addition, about the same structure and 1st effect as 1st Embodiment, the description is abbreviate | omitted using the same code | symbol.

  An annular light color boundary portion 18 is formed on the shade surface portion 17 of the shade 16 so as to correspond to the ring-shaped fluorescent lamps L1 and L2 having different emission colors. In the light color boundary portion 18, an annular step portion 31 is formed on the shade surface portion 17, and an annular boundary body 32 is attached to the surface (outer surface) of the step portion 31. The boundary body 32 has light shielding properties or translucency, and a lower surface is formed along a curved surface on the center side 16b of the shade surface portion 17, and an upper surface is separated from the outer diameter side 16a of the shade surface portion 17. .

  When three ring fluorescent lamps L1, L2, and L3 are lit at the same time, the outer diameter side 16a of the shade 16 corresponds to the emission color of the ring fluorescent lamp L1, with the boundary 32 of the light color boundary portion 18 as the eaves. The center side 16b of the shade 16 shines in white light corresponding to the emission colors of the ring-shaped fluorescent lamps L2 and L3.

  Therefore, with the boundary body 32 of the light color boundary portion 18 as a trap, the light color that the shade 16 shines can be clearly changed, thereby obtaining a high lighting effect and improving the design even when turned off. Can do.

  The lamp may be a lamp having three or more kinds of emission colors. In this case, the shade may be provided with a plurality of light color boundary portions corresponding to lamps having different emission colors.

  Further, the same effects can be obtained when the present invention is applied not only to a lighting fixture that uses a ring fluorescent lamp but also to a lighting fixture that uses a straight tube fluorescent lamp.
