[Problems to be solved by the device]

 In the conventional ceiling hanging lamp as described above, the incandescent lamp 6 emits a large amount of heat, and the large amount of heat is generated in the ceiling lamp hanging fixture by interacting with the heat emitted from the fluorescent lamps 4 and 5. The heat from the incandescent lamp 6 is radiated to the outside of the appliance from the heat radiation tube 14 via the back side of the incandescent lamp reflecting plate 7 because there is a risk of the cage and the appliance body 8 being destroyed. However, the heat emitted from the incandescent lamp 6 is indirect because it goes through the reflection plate 7, and there is a problem that the heat cannot be sufficiently emitted.

Further, since the incandescent lamp 6 is covered with the reflecting plate 7 having a shape in which the upper and lower ends of the hollow barrel are cut off, the light emitted from the incandescent lamp 6 becomes a spot light and the light 2 There was a problem that the living space was not evenly illuminated because it was mostly illuminated downward.

The present invention has been made to solve the above problems, and the heat emitted by the incandescent lamp can be easily released to the outside of the ceiling hanging lamp fixture, thereby providing high output and high illumination. An incandescent lamp is provided to obtain sufficient illuminance in the living space, and the light emitted from the incandescent lamp is mitigated by the fluorescent lamp to create shadows. The purpose is to diffuse the light and evenly illuminate the living space.

[0009]

[Means for Solving the Problems]

 The ceiling hanging lamp according to the present invention has a circular fluorescent lamp on the outside and an incandescent lamp on the inside, and is made of a synthetic resin that semi-transmits and diffuses light. An incandescent lamp cover with a trapezoidal cylindrical shape whose diameter increases toward is installed between the fluorescent lamps and the incandescent lamp, and is installed above the incandescent lamp cover to turn on the circular fluorescent lamp and the incandescent lamp. A device with a built-in device is provided with a cylindrical heat dissipation hole that communicates with the hollow disk-shaped heat dissipation hole of the incandescent lamp cover.

[0010]

[Action]

 The incandescent lamp cover heat dissipation hole and the main body heat dissipation hole of the ceiling hanging lamp according to the present invention work to raise the heat emitted from the incandescent lamp and the heat of the main body of the appliance as they are, and to let them out of the ceiling hanging lamp fixture.

The incandescent lamp cover also semi-transmits / diffuses the light emitted from the incandescent lamp to alleviate the shaded part of the fluorescent lamp with respect to the shade of the ceiling hanging lamp, and reflects it on a large area of the incandescent lamp cover. It diffuses and illuminates the living space with a uniform illuminance.

Further, in the incandescent lamp cover, invading objects such as insects that have invaded from both the heat dissipation holes and the lower surface of the shade and the lower surface of the incandescent lamp cover easily fall off between the shade and the incandescent lamp cover.

【Example】

 Example 1. An embodiment of the present invention will be described below. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, wherein 4 and 5 are fluorescent lamps having different diameters, 6 is a circular fluorescent lamp, and incandescent lamps are provided inside the fluorescent lamps 4 and 15, and 15 is a half light source. An incandescent lamp cover made of a synthetic resin that diffuses and diffuses, and is formed between the fluorescent lamps 4 and 5 and the incandescent lamp 6 in the shape of a truncated cone having a diameter increasing downward. It is larger than the diameter of the large-diameter circular fluorescent lamp 5, and is extended to a position where the large-diameter circular fluorescent lamp 5 cannot be seen from below. Reference numeral 8 denotes an instrument body which is installed above the incandescent lamp cover 15 and has a built-in lighting device such as an electronic ballast for lighting the circular fluorescent lamps 4 and 5 and the incandescent lamp 6.

Reference numeral 16 denotes a shade of the circular fluorescent lamps 4 and 5 having a shape in which the upper part of a hemisphere is cut out and the upper and lower surfaces thereof are opened, and 17 denotes an incandescent lamp for fixing the incandescent lamp cover 15 to the apparatus body from below. A cover mounting screw, 18 is an upper surface of the incandescent lamp cover 15, and a hollow disc-shaped incandescent lamp cover heat radiating hole opened on the outer periphery of the incandescent lamp cover mounting screw 17, and 19 is an incandescent lamp cover heat radiating hole 18 in the fixture body 8. A main body heat dissipation hole provided with a cylindrical hole communicating with each other, 20 is a shade heat dissipation hole formed by the upper opening of the shade 15, and forms a separate air passage from the main body heat dissipation hole 19 to form the circular fluorescent lamp 4, The heat radiated from 5 is radiated to the outside of the ceiling hanging lamp fixture.

In the ceiling hanging lamp 2 configured as described above, the circular fluorescent lamps 4 and 5 or one of the circular fluorescent lamps 4 and 5 is lit by the operation of the instrument body 8 having a built-in lighting device. By doing so, the emitted light passes through the incandescent lamp cover 15 and the shade 16 and illuminates the living space.

At this time, the heat of the inner circumference of the instrument body 8 generated by turning on one of the circular fluorescent lamps 4 and 5 or one of the circular fluorescent lamps 4 and 5 rises in the middle of the chain line arrow A, that is, from the instrument body 8 part. Then, the heat generated from the circular fluorescent lamps 4 and 5 and the heat of the outer circumference of the fixture main body 8 rises as they are from the main body heat dissipation hole 19 to the outside of the ceiling hanging lamp fixture, and rises as it is, as indicated by a chain line arrow B. It is emitted outside the ceiling hanging lamp fixture.

Further, when the incandescent lamp 6 is turned on by the operation of the main body 8 of the lighting device, the emitted light is reflected directly and on the incandescent lamp cover 15, and a part of the incandescent lamp cover 15 is removed. It penetrates and further penetrates the shade 16 to illuminate the living space.

Since the shape of the incandescent lamp cover 15 is formed in a gentle curve, the light emitted from the incandescent lamp 6 is reflected in many directions, and the light of the incandescent lamp 6 is reflected. It is possible to illuminate the surface of the shade 16 without transmitting the diffused and strong shadow of the fluorescent lamp, and also to transmit the shade 16 to illuminate the upper direction of the living space.

Then, the heat emitted from the incandescent lamp 6 rises as it is, passes through the incandescent lamp cover radiating hole 18, passes through the main body radiating hole 19, and is radiated to the outside of the ceiling hanging lamp. It

Further, the circular fluorescent lamps 4 and 5 and the incandescent lamp 6 are simultaneously turned on by the operation of the main body 8 of the built-in lighting device, so that the light emitted from the circular fluorescent lamps 4 and 5 is emitted from the incandescent lamp cover 15 and the shade. The light emitted from the incandescent lamp 6 through 16 and the living space is reflected directly and by the reflecting plate of the incandescent lamp cover 15, and a part of the light also passes through the incandescent lamp cover 15 and further through the shade 16 for living. Illuminate the space.

At this time, the heat of the inner circumference of the instrument body 8 generated by lighting one of the circular fluorescent lamps 4 and 5 or the circular fluorescent lamp 4 or 5 and the heat emitted from the incandescent lamp 6 are indicated by chain line arrows A. Ascends as it is, passes through the heat dissipation hole 18 of the incandescent lamp cover, passes through the heat dissipation hole 19 of the main body, and is discharged to the outside of the ceiling hanging lamp fixture.

Further, the heat generated from the circular fluorescent lamps 4 and 5 and the heat of the outer periphery of the fixture body 8 rise as they are, as indicated by the chain line arrow B, and are radiated to the outside of the ceiling hanging lamp fixture through the shade radiation holes 20. It

Example 2. In the first embodiment, the bottom edge of the incandescent lamp cover 15 is extended to a position where its diameter is larger than the diameter of the large-diameter circular fluorescent lamp 5, so that the large-diameter circular fluorescent lamp 5 cannot be seen from below. However, the same effect can be expected when the incandescent lamp cover 15 has a size up to the end of the gentle curve. At this time, invaders such as insects are more likely to come out.

Example 3. FIG. 2 is a vertical cross-sectional view showing a third embodiment of the present invention, in which a shade 16 has a hemispherical shape that covers up to the upper part of a fixture body 8 in which a lighting device such as an electronic ballast is built, and its upper peripheral surface is circularly opened. Then, a protrusion side that is folded back is formed inside the opening peripheral edge. Reference numeral 21 is a shade fixing tool for detachably fixing the shade 16 to the instrument body 8. A shade discharging hole 20 is formed on the side surface thereof as an outlet for the heat emitted by the circular fluorescent lamps 4 and 5. In the vicinity of the hole 20, it merges with the air passage from the body heat dissipation hole 19.

With this structure, the heat emitted by the circular fluorescent lamps 4, 5 and the heat of the outer periphery of the instrument body 8 (chain line arrow B) and the heat of the inner periphery of the instrument body 8 emitted from the body heat dissipation hole 19 The heat from the incandescent lamp 6 (broken line arrow A) intersects in the vicinity of the shade heat dissipation hole 20 and draws out heat from each other, and a further heat dissipation effect can be expected.

Example 4. In the third embodiment, the shade heat dissipation hole 20 is provided on the side surface of the shade fixture 21 that is detachably fixed around the convex portion on the upper surface of the instrument body 8 in which the lighting device such as the electronic ballast is incorporated. When the shade 16 covers the entire device body 8 and is detachably fixed to the upper end of the convex portion on the upper surface of the device body 8, the shade radiation hole 20 is provided on the upper surface of the shade 16.

With this configuration, the heat emitted from the circular fluorescent lamps 4 and 5 is the heat of the inner circumference of the appliance main body 8 and the heat emitted from the incandescent lamp 6 which are emitted from the main body heat dissipation holes 19 as in the third embodiment. Further, the heat of the outer circumference of the fixture body 8 and the heat dissipating holes 20 once intersect with each other, and the heat is drawn out from each other, and the heat is released through the shade dissipating holes 20 to the outside of the ceiling hanging lamp fixture, so that a further heat dissipating effect can be expected.

Example 5. In any of the above embodiments, the shape of the incandescent lamp cover 4 is a shape that is curved inward with the incandescent lamp 3 as the center, but conversely, when it is curved outward, the same reflection / diffusion of light is obtained.
