Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an incandescent lamp lighting fixture of a type in which an incandescent lamp is housed in a container, and is particularly suitable as a small andon-shaped stand.

[Background of the invention]

If you store an incandescent lamp in a small container, it will overheat f7)c.

If the container is made of metal, it will become dangerously hot to touch. However, if it is made of synthetic resin, it is necessary to use an expensive material with particularly high heat resistance σ).

One heat countermeasure is to provide heat dissipation holes 2 here and there in the container 1, as shown in Figure 1, for example.
Particularly small ones will overheat even in this case.

For this reason, it is desirable to, for example, completely open the upper surface of the container 1 to further improve its heat dissipation characteristics.

By the way, if the top side of the container is opened, it is easy for dust and dust to enter the container 1 through the opening, so if necessary, cover the opening and remove it.

However, if a lid is provided, there is a risk of undesirable consequences such as closing the lid and turning on the incandescent lamp.

Koi 1. Then, there is a problem in terms of overheating or heat resistance θ).

[Purpose of the invention]

The present invention is devised to allow the incandescent lamp to be lit only when the heat dissipation σ) holes are sufficiently open, thereby eliminating the problems of overheating and heat resistance.

[Invention O) Overview]

In the present invention, a cylindrical container with a bottom is used, and an incandescent lamp is placed inside the container. This container 0) has an opening on the top side. The stone is mainly used for heat dissipation. The opening ζ moss can be opened and closed O) A lid is attached.

Ru. In addition, the degree of opening of the hole caused by this lid is detected, and the differential force S
A switch element is used which allows the rated lighting of the incandescent lamp to open beyond a certain limit.

This is to prevent rated lighting under the opening degree below the limit required for heat dissipation7, and to limit the heat generation caused by incandescent lamps.C.The lid and switch element as a whole are a kind of manual flashing. Configure the switch. Therefore, it is not necessary to provide a separate blinking switch.

r Invention 0) Embodiment] Hereinafter, an embodiment of the present invention shown in FIGS. 2 and 3 will be described in which the present invention is applied to an andon-shaped desk lamp. Reference numeral 10 denotes a cylindrical container with a bottom, and the upper surface thereof is completely open in this embodiment. The openings 20 serve both as heat radiation and light transmission.

3. An incandescent lamp is fixed to the center of the bottom of the container 10. 4 is a lid attached to the periphery of the opening of the container 3 via a hinge 5, and opens and closes the opening 20. .

Reference numeral 6 denotes a push button switch, which has two fixing holes around the opening of the container 10. The push button 62 of the switch 6/71 is opposed to the inner surface of the lid 4, and the operation key 11. Ru. The blinking of the incandescent lamp 3 is controlled by a single switch 6t, and when the lid 4 opens beyond a certain limit, the lamp 3 lights up at its rated value.

On the other hand, when the cover 4 is slightly +T or at least completely closed, the light goes out.When the lid 4 is closed, the push button 62 is pressed on the inside of the lid 4 so that As described above, the push-button switch 6 detects the degree of opening of the lid 4, and serves as a switch element to turn on the incandescent lamp 3 at its rated value and turn it off accordingly. 8 that works
92 is a cord, and 93 is a plaque.

As shown in Figure 2, when the lid 4 is closed and the internal incandescent lamp 3 is turned off, it is difficult for dust and dirt to get inside, and the lid does not get in the way, making it convenient for storage. be. If the incandescent lamp 3 were to turn on at its rated value in this situation, the heat emitted from it would be trapped, causing an overheating problem or a heat resistance problem, but in reality, the incandescent lamp 3 would not turn on because of the switch element 6. In this way, you will not accidentally turn on the light while the lid 4 is closed. On the other hand, the lid 14
Under the situation shown in FIG. 3 when the incandescent lamp 3 is fully opened and the incandescent lamp 3 is lit at its rated capacity, a large amount of heat is dissipated from the incandescent lamp 3.

This heat is effectively released to the outside of the container 10 through the opening 20. Therefore, since the container 10 or the lid 4 does not overheat, it is also possible to construct the strainer from an inexpensive synthetic resin material with poor heat resistance.

Along with the heat, light from the incandescent lamp 3 is also emitted through the aperture 20, but most of that light is reflected off the back surface of the lid 4 and diverted toward the lower hemisphere, so the light is used efficiently. .

Next, more specific embodiments shown in FIGS. 4 to 9 will be described. It should be noted that the parts numbers shown in FIGS. 2 and 3 will be quoted as is.

The cylindrical container 10 with an open bottom and an open top is a molded product made of polystyrene resin. 1 in Fig. 5 indicates that the cylindrical portion 12 and the bottom plate portion 14 are elastically fitted in a concave and convex manner.
6 corresponds to a fitting part. The diameter of the cylindrical part 2 becomes slightly narrower as it goes upward, but this is to improve stability when placed and for design reasons. The lid 4 is an AB8 resin molded product, and includes a disc portion 42 and a handle 44 arranged in a diametrical direction on its upper surface. The disk portion 42 is for opening and closing the aperture 20 on the upper side of the lid 4, and the handle 44 is for opening and closing the opening. Aluminum ram is vapor-deposited on the back surface (lower surface) 46 of the disk portion 42 to increase its reflectance, but one method is to attach a mirror plate to this portion.

The bottom plate part 14 has a trapezoidal shape, and the main incandescent lamp 3 is mounted at the center of the upper surface, and the main incandescent lamp 3 is mounted slightly outward from the center.
, Attach the auxiliary light 30i at the top position. Further, a rotary cord reel 94 is disposed inside the lower surface of the cylindrical portion 12.
ing. Therefore, when the cord (shown in the figure) extending to the plug 93 is wound, the result is as shown in FIG. 95 is the bottom plate part 12
A fall detection switch is fixed at a position near the top end of the switch, and its push button 96 faces the bottom side. When an incandescent lighting fixture is placed on the floor, the push button 96 is pressed on the floor, and when the fixture falls over, it disappears.

7 is a support made of ABS resin, and is fixed to the - side of the container 17. ing. The leg piece 71 at the lower end of the column is a concave-convex fit with the edge of the bottom plate part 14, and set screws 79 are also used, but these are for fixing the column 7. The support column 7 has a hollowed-out U-shaped cross section θ), and in particular, the upper end portion ζ is integrally formed with a hinge half body 72. On the other hand, another hinge half 47 is formed at the edge of the lid 4, and the hinge halves 72, 47 overlap each other, and the bolt part 51.
The switch element 6 is fixed in the hole n in the pillar 7F, which together with the nut part 52 constitutes the hinge 5, and in the inside lζ thereof. This is a kind of slide switch, and its actuator 63 is operated by a connecting piece 641 whose one end is engaged with the connecting piece 64, whose other end is connected to the hinge half 47. It engages with the protrusion 65 provided. This protrusion 65 is formed on the side of the hinge half 47 facing the other hinge half 72, and does not reach the hinge half 72. therefore,
It does not affect the function of the hinge. Hinge half 47
The bank-like protruding peripheral edge in is the sliding surface c'-fj with the mating hinge half 72, but the protrusion 65 is located on the inside thereof, and there is a roller slightly outward from the center of rotation. A portion of the bank-like protruding edge is notched. This notch 4
Reference numeral 9 denotes the πth piece into which the connecting piece 64 is loosely inserted. As the lid 4 is opened and closed, the hinge half 470) protrusion 64 rotates around the bolt portion 51. This movement is transmitted to the actuator 63 of the switch element 6 via the connecting piece 64.

The circuit diagram is as shown in Figure 9 (O), and when the fall detection switch 95 detects the fall of the appliance, when this part is open, the incandescent lamp 3. Both auxiliary lights 30 are turned off. If the fall detection switch 95 is closed, both lights 3,
The blinking of 3o is controlled primarily by the switch element 61, and therefore by the opening/closing of the lid 4 71. specific l
(When cover 4 is closed, both lights 3 and 3o are
This light goes out. In a situation where the lid 4 is slightly opened, only the auxiliary light 3o is lit. In addition, when the lid 4 is fully opened beyond a certain limit, the auxiliary light 30 is turned off and the main incandescent light 3 is turned on. The heat is dissipated through the sufficiently opened aperture 2o, and a portion of the R light is reflected toward the lower hemisphere from the back surface 46 of the lid 4, illuminating the floor surface in the vicinity.

The upper end of the cylindrical portion 12 has an obliquely cut edge. This is to make it easier for reflected light to pass through. Is lid 4 complete? The auxiliary light 30 turns on when the lid is opened 30 degrees and the lid 4 is almost horizontal, and the incandescent light 3 turns on when the lid is opened 60 degrees. Light. The cylindrical part 12 is semi-transparent, and light also comes out from there.

The incandescent lamp 3 of the example has a power of 4oW. Further, the maximum diameter of the cylindrical portion 12, that is, the diameter in FIG. 7, is 150 W, and the whole is compact. However, even if the lid 4 is opened 60 degrees and the incandescent lamp 3 is turned on, there is no thermal problem. If the lid 4 is closed and the rated light is on, then the container 10. There is a risk that the lid 4 will deform due to heat, so it cannot be put into practical use!
Become. For this reason, it is necessary to make design changes such as changing the resin material to an expensive one with a high heat resistance grade, lowering the rated capacity of the incandescent lamp 3, and making the overall shape larger. becomes.

Reference numeral 19 in FIGS. 4 and 5 is a boundary line shown for reference, and if the color of the cylindrical portion 12 is changed above and below this, the entire structure becomes reminiscent of a bird's shell. In this case, the highlight is the hinge half body 47.72, and the mouth is the handle 4.
It is 4.

The embodiments shown in FIGS. 2 and 3 and the embodiments shown in FIGS. 4 to 9 are of the type in which the incandescent lamp 3 or the C auxiliary lamp 30 are made to flicker one by one. It is also possible to change this point to a dimming method. For example, a cylindrical star type dimming circuit (not shown) is installed, a variable resistor for gate control is set at position 6 in FIG. Let's have it done. In this way, we will dim the incandescent lamp 3 in the same figure.
It is not necessary to have a annex. In both cases, the setting is such that when the lid 4 is opened beyond a certain limit, the incandescent lamp 3 is allowed to turn on at its rated value, and when it is completely closed, the lamp is turned off. This is because it doubles as a normal blinking switch.

FIG. 10 shows an idea of an embodiment of the invention, and the overall appearance of the container 10 and lid 4 is similar to the one shown in Figure 10.
ing. The lid 4 is the root of one side of the house, and when you open it in the direction of the arrow, you will see a 2° opening. In this case, the opening 2o is not the entire upper surface side of the container IQI71,
Although it is about half of that, a considerable heat dissipation effect can be obtained even with small stones.

Above σ) The lid 4 in each embodiment is of a type that can be opened and closed at an angle from the other end using a hinge 5. Instead,
For example, the lid 4 in FIG. 6 may be of a type that opens and closes in the same position vertically along a guide rail (not shown) extending from the container 10.

〔Effect of the invention〕

The present invention includes a lid for opening and closing the heat dissipation opening on the top side of the container, and a switch element for detecting the degree of opening of the lid that is operated by a manual flashing switch. The open stone, nake n, is made so that the incandescent lamp inside the container cannot be lit at its rated value. For this reason, it is possible to provide a device whose overall size is small compared to the capacity of an incandescent lamp.In addition, it is possible to effectively avoid undesirable situations such as overheating or thermal deformation of the container or lid. This improves safety and extends life.
