Description

[Detailed description of the invention] The invention relates to a fluorescent lamp device that is compatible with incandescent light bulbs and can save power.

This type of fluorescent lamp device consists of a lighting circuit consisting of a roughly saddle-shaped fluorescent lamp with U-shaped bends in three places, a ballast, a lighting tube, etc. The fluorescent lamp and the lighting circuit are mounted in a housing case, and the outer periphery of the fluorescent lamp and lighting circuit is covered with a light-diffusing glove that is covered with the housing case.

By the way, since fluorescent lamps and lighting tubes usually have a shorter lifespan than ballasts, it is desirable that they can be easily replaced when the lamps and the like reach the end of their lifespans.

However, the above-mentioned conventional equipment does not take into consideration this replacement, and therefore, the entire equipment had to be replaced with a new one simply when the fluorescent lamp or lighting tube reached the end of its lifespan. .

Therefore, a structure can be considered in which the glove and the fluorescent lamp are detachably attached to the housing case, and only the fluorescent lamp alone can be replaced.

If this replacement work is performed by a general consumer. First, remove the glove to expose the lamp to the outside, and then pull it out in this state. However, if you grip the lamp too tightly during this process, the pulp of the fluorescent lamp for this device will be used for general lighting. Because it has a smaller diameter and thinner wall than a fluorescent lamp, there is a risk of damage.

In particular, the saddle-shaped fluorescent lamp is fixed in such a manner that its both ends face toward the housing case, and the pair of curved parts face toward the top of the globe.

During replacement, there are many opportunities to grasp this curved portion, and stress is therefore concentrated on the curved portion, causing problems such as the valve being more likely to be damaged.

This idea was created based on these circumstances.
Even when the curved fluorescent lamp reaches the end of its lifespan, it can be easily replaced.

Moreover, there is no need to hold the lamp directly when replacing it.
An object of the present invention is to provide a fluorescent lamp device with no risk of lamp damage.

That is, in order to achieve the above object, the present invention accommodates a stabilizer connected to one terminal of the cap in a housing case equipped with a two-terminal cap, and also houses the stabilizer connected to one terminal of the cap in the housing case. A translucent outer enclosure is provided with a first power supply terminal connected to the device and a second power supply terminal connected to the other terminal of the base, and is connected to the housing case so as to be able to come into contact with and be separated from the housing case. The container houses a curved pipe lamp having substantially U-shaped bent portions at three locations between both ends where the electrodes are located, and the envelope includes a starting circuit for the electrodes. A pair connected to the end opposite to the continuous side and detachably connected to the first and second power supply terminals in a state where the envelope and the housing case are connected to each other. The percentage is that the electrical contacts are installed.

The present invention will be explained below based on an embodiment shown in the drawings.

The glove 16 is preferably made of a light-transmitting polycarbonate resin, and is colored light-diffusing white by mixing a light-diffusing material into the resin.

The glove 16 has a fitting protrusion 18 protruding from the inner peripheral surface on the opening 11 side of the glove support flange 1.
By fitting into the fitting recesses 19 provided on the outer circumferential surface of the support plate 16a, the support plate 16a is connected and fixed.

Note that the globe 16 and the support plate 16a may be connected to each other by screwing or using an adhesive.

A curved fluorescent lamp 20 is mounted on the globe-side surface of the lamp mounting portion 12 so as to be located inside the globe 16.

That is, in this curved tube-shaped fluorescent lamp 20, a straight glass bulb is bent into a substantially U-shape at the center between its two ends to form a first curved portion 21, and both ends thereof are bent into a substantially U-shape. A pair of 20th bent portions 22.22 are formed by forming a substantially U-shaped bend in a direction substantially perpendicular to a plane including the U-shaped portion, and by this two bending steps, a portion between both end portions 32.32 is formed. It has three U-shaped curved parts 21, 22, 22, and its overall shape resembles a horseback saddle, so it is called a saddle-shaped fluorescent lamp.

Such a curved fluorescent lamp 20 has both ends 32
, 32 and the first curved portion 21 are opposed to the lamp mounting portion 12, and in this embodiment, the first curved portion 21 includes a pair of locking bowls 23, which are protruded above the lamp mounting portion 21. It is clamped and fixed by 23.

Incidentally, filaments 25.25 as electrodes are provided in both ends 32.32 of the curved fluorescent lamp 20.

A lighting tube 24 as a starting circuit for the fluorescent lamp 20 is mounted on the lamp mounting portion 12 and is located between both ends 32 and 32 of the fluorescent lamp 20. One lead wire 26a, 27 is connected to the filament 25, 25 of the fluorescent lamp 20, respectively.
a is connected.

In addition, 28 indicates these filaments 25, 25 and lighting tube 2.
This is a capacitor connected in parallel between 4 and 4.

Furthermore, a pair of electrical contacts 29.29 are protruded from the surface of the lamp mounting portion 12 on the housing case 1 side. Child 29.29 is the above filamen) 25,25
The lead wires 26b and 27b are connected to the other lead wires 26b and 27b.

The electric contacts 29, 29 are fitted individually to the power supply terminals 9, 10 in a state in which the support plate 16a is connected to the housing case 1, and are arranged between the clamping claws 8, 8 and 8, 8. The lamp 2 and the ballast 5 are electrically connected to the fluorescent lamp 20 by this insertion.

A ventilation hole 30 is provided at the top of the globe 16 to communicate the inside and outside of the glow hood 6, and a communication hole 31 is provided at the center of the lamp mounting portion 12 to communicate between the inside of the globe 16 and the inside of the housing case 1. It is provided.

According to such a configuration, the curved fluorescent lamp 20 or the lighting tube 24 and the ballast 5 can be separated by simply pulling out the entire envelope 11 from the housing case 1 in the axial direction of the base 2. can.

Therefore, when the fluorescent lamp 20 or lighting tube 24 reaches the end of its life after long-term use, only the envelope 11 side needs to be replaced, and the housing case 1 side containing the relatively expensive ballast 5 can be replaced. can be used again as is.

Therefore, there is no need to replace the entire device with a new one, which is economical.

Moreover, in this case, since the fluorescent lamp 20 remains housed in the envelope 11, there is no need to hold the lamp 20 directly with your fingers when replacing it, and there is therefore no risk of the lamp 20 being damaged. It is safe.

Furthermore, since the glove 16 in the above embodiment is made of synthetic resin, there is a risk of deterioration and discoloration due to near ultraviolet rays emitted from the fluorescent lamp 20. However, according to the configuration of this embodiment, the glove 16 also Since the light lamp 20 is replaced at the same time, there is no risk that the globe 16, which serves as a secondary light emitting surface, will absorb light, and a decrease in luminous flux will not occur.

Furthermore, if the lighting tube 24 is also housed in the globe 16 as in this embodiment, the lighting tube 24 and the fluorescent lamp 20 have substantially the same lifespan, so the lighting tube 24 can also be replaced at the same time. In addition, even if the replacement time is before the end of its lifespan, there will be no economic problem.

Further, according to this configuration, there is no need to provide a special structure on the housing case 1 side for removably attaching the lighting tube 24, and the lighting tube 24 itself can be used as is.

Furthermore, both the puffer fish case 1 side and the envelope 11 side can have two terminals, which has the advantage of simplifying the electrical connection mechanism between these two terminals.

In the above embodiment, the housing case and the support plate were connected by fitting the protrusion and the recess, but for example, a bayonet type or a hook sealing type was adopted for the connection structure between the contact and the power supply terminal. The connection portion may also have the function of connecting the housing case and the support plate, and the special connection structure as described above may be omitted.

Further, in the above embodiment, a lighting tube is used as the starting circuit, but an electronic circuit may be used instead of the lighting tube, and in this case, it is desirable to provide the electronic circuit on the housing case side.

Furthermore, a communication hole may be provided on the circumferential surface of the housing case to communicate the inside and outside of the case. If this is done, the vertical lighting state with the cap facing upward, which is the most common lighting direction of the fluorescent lamp device, can be provided. In other words, the outside air flows through the glove and the housing case, promoting the heat exhaust effect.

According to the present invention described in detail above, the fluorescent lamp and the ballast can be easily separated by simply pulling out the entire envelope from the housing case, so that the fluorescent lamp reaches the end of its life. In this case, only the envelope side needs to be replaced with a new one, and the ballast and cap can be used repeatedly, which is economical.

At the same time, since the fluorescent lamp remains housed in the envelope during replacement, there is no need to hold the fluorescent lamp directly with your fingers, and there is no risk of damage to the fluorescent lamp. It is safe and effective.
