The present invention relates to a fluorescent lamp unit, and more particularly to a fluorescent lamp unit having a fall prevention function of a small cloud range on the installation surface.

Compared with the related art, a fluorescent lamp unit has been developed in which a ballast or a high frequency lighting circuit part is accommodated in a cover having a screw-type clasp for an incandescent lamp at one end, and a fluorescent lamp is attached at the other end of the cover.

The above-described fluorescent lamps are fluorescent lamps of various shapes, such as U-shaped, W-shaped, saddle-type.

The lamp unit described above is compatible with incandescent lamps and is being used as a light source for energy saving.

Such lamp unit has a circular cross section of the aforementioned cover, which is perpendicular to the axial direction of the lamp unit, and the fluorescent lamp attached to the cover has a diameter smaller than the diameter of the cover.

Many conventional lamp units have also used heavy ballasts.

In this case, its center position is determined by the position of the ballast, and the ballast has been installed in the center of the cover to improve the balance of the entire lamp unit.

Therefore, the central position of the entire lamp unit is near the maximum diameter of the cover or is closer to the clasp than this maximum diameter, and the lamp unit described above is transverse to the mounting surface of the table, the plate, etc. (the length direction of the lamp unit described above). In the case of installation, the cover part having a large diameter or the part having a large diameter and the clasp are brought into contact with the mounting surface of the table or the like.

However, in the above-described fluorescent lamp unit, the fluorescent lamp is used while the fluorescent lamp is exposed, and the fluorescent lamp is coated with a transparent glove.

Here, in the lamp unit used in the state where the fluorescent lamp is exposed, the cross section of the cover with the lamp is circular as described above, and the diameter of the above-described type lamp is smaller than that of the cover.

The lamp unit described above usually has a center line in the axial direction substantially parallel to the above-described mounting surface so that only the outer circumferential surface of the cover portion having a circular cross section or the outer circumferential surface of the cover portion and the circumferential surface of the clasp are described above. It is located in contact with one installation surface.

Since this lamp unit is circular in the cross section of a cover part, it is easy to produce clouds on the installation surface in the direction perpendicular to the axial direction of the lamp unit, that is, the round circumference of the cover part.

As a result, the damage caused by the fluorescent lamp unit colliding with another object and the damage caused by the fall from the installation surface easily occurred.

In addition, even if the fluorescent lamp is coated with a transparent glove, if the cross section is circular, the aforementioned fluorescent lamp is such that the circumferential surface of the cover or the transparent glove contacts the installation surface described above.

Therefore, the lamp unit is rolled along the axial direction of the lamp unit along the circumferential surface of the cover part or the glove on the installation surface, and as the inertia of the cloud occurs, such as when the fluorescent lamp is exposed, the damage caused by collision with another body, the installation surface It could cause damage due to falling from the ground.

Accordingly, an object of the present invention is to provide a curved fluorescent lamp to a cover having a circular cross section, wherein the circumferential surface of the cover or the transparent glove contacts a mounting surface such as a table and contacts the mounting surface of the lamp device on the mounting surface. The present invention provides a fluorescent lamp unit that can prevent damage caused by colliding with another object by rolling in the vertical direction and falling by falling from the installation surface.

According to one embodiment of the present invention, a fluorescent lamp device has a fluorescent lamp 46 having an electrode at an end and encapsulating a discharge gas therein, and a fluorescent lamp in which a maximum portion of the cross section is circular and the largest diameter portion is described above. A base member 12 having a diameter larger than the diameter of 12 and having the above-described fluorescent lamp attached to one end and having a clasp 18 formed at the other end thereof, and being accommodated inside the base member and having a fluorescent lamp and a faucet; It is electrically connected to the metal part and consists of a lighting circuit component 34, etc. for controlling the lighting of the above-described mold hole lamp, the lighting circuit component 34 described above is horizontal to the axis connecting the lamp unit to the fluorescent lamp and the clasp. The center of the lamp unit is attached to the position of the fluorescent lamp in the maximum diameter portion of the base member so that the above-described lamp unit is inclined when installed on the installation surface, the fluorescent lamp is formed a curved discharge path The outer shape of the base member is formed in the shape of a rice bowl, and the discharge path has electrodes at each end and two U-shaped discharge paths formed by fusion of the other ends. The base member has an attachment portion for attaching a lamp striking in the extending direction of the fluorescent lamp.

According to another embodiment of the present invention, a fluorescent lamp device has an electrode at an end portion, a fluorescent lamp in which discharge gas is enclosed, and a diameter of the above-described fluorescent lamp of the largest diameter part in a cloud shape of the largest part of the cross section. A base member having a larger diameter and having a fluorescent lamp attached to one end and a clasp formed at the other end, and housed inside the base member described above and electrically connected to the fluorescent lamp and the clasp to light the fluorescent lamp. The lighting circuit component described above is attached to a position eccentric to the axis of the lamp unit through which the center of the lamp unit passes through the center of the circular cross section of the largest diameter part.

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

1 to 7 show one embodiment of the fluorescent lamp unit according to the present invention.

In FIG. 1 and FIG. 2, the fluorescent lamp unit 10 is provided in the transverse direction with respect to the mounting surface P, such as a table, and "12" is a synthetic resin cover.

As shown in FIG. 3, the cover 12 has a substantially circular rice bowl shape in cross section, and at one end, a cylindrical portion 16 having a small diameter is provided to protrude from the opening 14 at the other end.

A clasp 18 is deposited on the cylindrical portion 16.

The clasp 18 is made of, for example, a screw type such as E26, and is fixed to the cylindrical portion 16 by an adhesive or caulking.

Moreover, the ventilation hole 22 which communicates the room 20 mentioned later in the cover 12, and the exterior is formed in the side wall of the cover 12. As shown in FIG.

The opening 14 at the other end of the cover 12 described above has a maximum diameter, and the closing member 24 made of, for example, synthetic resin is attached to the opening 14.

In other words, the opening 14 of the cover 12 described above is closed by the closing member 24.

The closing member 24 is composed of a pair of disk-shaped partition plates 26 and 28 spaced apart in the axial direction, and the partition plates 26 and 28 are connected ribs 30. Are opposed at predetermined intervals.

Accordingly, the insulating air layer 32 is formed between the two partition plates 26 and 28 facing each other apart from each other.

The insulating air layer 32 is in communication with the outside over the entire circumference of the partition plates 26 and 28.

One disc-shaped partition plate 26 of the closing member 24 is formed with an edge wall 34 into which the opening 14 of the cover 12 is fitted.

The closure member 24 is attached to the cover 12 by using a device such as adhesive or caulking or engagement with the opening 14 of the cover 12 covering the fitting edge wall 34. It is fixed.

Thus, the room 20 partitioned from the outside by the closure member 24 is comprised in the cover 12. As shown in FIG.

Each part of the high frequency lighting circuit 34 is accommodated in the room 20 in the cover 12.

This high frequency lighting circuit 34 is composed of a starting circuit 36 and a stabilizing circuit 38 as shown in FIG.

The starter circuit 36 and the stabilization circuit 38 are well known circuits, respectively. The starter circuit 36 is a circuit composed of components such as thermistor, thyristor element, etc., and the stabilization circuit 38 includes a front rectifier and a smoothing capacitor. , Transistor, resonant capacitor, and oscillating coil.

The electric circuit of FIG. 5 is an example of the starter circuit 36 and the stabilization circuit 38 described above.

The starting circuit component 360... Of the starting circuit 36 is attached to the substrate 40 for the lighting circuit, and the substrate 40 is fitted to the disk-shaped partition plate 26 to provide a device such as caulking. It is fixed.

The substrate 40 is provided with a wrapping terminal 44 for connecting the lead wires 42a and 42b which will be described later.

In the connecting ribs 30... Of the blocking member 24, a receiving portion 48 protruding toward the inside of the chamber 20 is formed to face the end portion of the fluorescent lamp 46, which will be described later.

These accommodating parts are accommodated in a thin tube 50 to be described later provided to project at each end of the fluorescent lamp 46.

And the long and thin slit-shaped through hole 52 is opened in the wall facing the room 20 of the accommodating part 48. As shown in FIG.

The external lead wires 42 a, 42 b, 42 c, 42 d, which are led from the end of the fluorescent lamp 46, pass through these conductive holes 52. Therefore, the outer 42a, 42b, 42c and 42d are connected into the cover 12 through the through hole 52.

On the other hand, the stabilization circuit component 280 of the stabilization circuit 38 is attached to a circuit board 54 different from the above-described substrate 40.

The substrate 54 is provided such that the insertion slit 56 for frit wiring the external lead wires 42c and 42d and the lapping terminal 58 for connecting the external lead wires 42c and 42d protrude. .

The substrate 54 to which the component 380 of the stabilization circuit 38 is attached is fixed to the support 60 formed at predetermined intervals on the inner surface of the circumferential wall 34 to be fitted.

Therefore, the circuit board 40 to which the component 360 of the starter circuit 36 is attached and the circuit board to which the component 380 of the stabilization circuit 38 are attached are arranged in the axial direction (O ₁ − in FIG. 1) in the cover 12. O direction indicated by the line ₁₎ to maintain the spacing is arranged while.

In addition, the circuit board 54 with the stabilization circuit component 380... Is electrically connected to the clasps 18 described later via, for example, lead wires (not shown).

Then, the clamp 18 is inserted into a socket (not shown) on the power supply side (not shown) to apply a voltage to the lamp device 10.

A curved fluorescent lamp 46 is attached to the other disk-shaped partition plate 28 of the blocking member 24.

The curved fluorescent lamp 46 may be U-shaped or W-shaped, for example, but here, two U-shaped glass tubes 62a and 62b are provided together to form a saddle-shaped discharge path. Shall be used.

In the fluorescent lamp 46, a rare gas such as argon and water temperature are sealed, and a fluorescent lamp 46 is coated.

The fluorescent lamp 46 is formed by placing two glass tubes 60a and 60b which have been previously processed into a U shape in parallel with each other and being fused and joined to each other as a fusion unit 62.

The electrodes 64a and 64b are sealed at the other ends of the two U-shaped glass tubes 60a and 60b described above.

In addition, at the ends of the two U-shaped traverse tubes 60a and 60b described above, the remaining fine pipe 50 is formed to protrude from the exhaust pipe, and the external lead wires 42a and 64b connected to the electrodes 64a and 64b are provided. 42b) 42c and 42d protrude.

In the fluorescent lamp 46 configured as described above, both ends of the glass tubes 60a and 60b are fixed to the partition plate 28 of the closure member 24 with an adhesive 66.

The fluorescent lamp 46 is because it is configured to bond the two glass tubes (60a) (60b) as described above, around a center line of the center of the fluorescent lamp unit 10 (0 ₁ -0 ₁ line) ratio It is circular.

The diameter of the fluorescent lamp 46 is smaller than that of the opening 14 of the cover 12.

The cross section of the fluorescent lamp 46 and the bonding place by the above-mentioned adhesive 66 are covered with the cover plate 68 made of synthetic resin formed from the lower surface.

That is, the above-mentioned adhesive place is not visible from the outside.

The cover plate 68 described above is fixed to the disk-shaped partition plate 28 by an adhesive or a fitting device.

In the cover plate 68, each end of the two glass tubes 60a and 60b is directed to the fusion surface 62 bonded to each other so that the fusion portion 62 is concealed from the outside. 70b) is installed to protrude.

This is because the fusion shape of the glass in the fusion | melting part 62 is not fixed.

In addition, since the fluorescent material film is not formed in the fusion portion 62, the luminescent portion 62 glows while the lamp is turned on.

Therefore, the fusion | splicing part 62 is covered and concealed by the concealed edge part 70a, 70b, as FIG. 6 and FIG.

In the fluorescent lamp unit 10 configured in this way, for example, the height (center line 0 ₁ -0 ₁ direction) of the lamp unit 10 about 180㎜, the length of the fluorescent lamp 46 is about 100mm, the cover (12 Let the maximum diameter of) be about 65mm.

If the total weight of the lamp unit 10 is about 250 g, the lighting circuit component 360... And the stabilization circuit component 380... Are about 70 g and the weight of the glass tubes 60a, 60b is about 100 g.

By this the center of the same unit as the center G1 G1 is set to the fluorescent lamp (46) than the maximum diameter portion of the cover 12 in the axial direction of the unit 10 (the center line 0 ₁ -0 ₁ direction).

The center G1 is formed by moving the circuit board 40 and the start-up circuit component 36... Of the high frequency lighting circuit 34 in the direction of the opening 14 of the cover 12, for example. It is in the same position.

Next, explaining the operation of the embodiment, the fluorescent lamp unit 10 is used by fitting the clasp 18 to a socket (not shown) on the power supply side.

When the power is turned on while the clamp of the lamp unit 10 is fitted to the above-mentioned socket, the parts 360... 380... And the lead wire 42a on the circuit boards 54, 40 from a lead wire not shown. Current flows through the electrodes 42b, 42c, and 42d to the electrodes 64a and 64b.

When the discharge is started between the positive electrodes 64a and 64b, the electrical energy is converted into ultraviolet radiation in the discharge space in the glass tubes 60a and 60b to excite the fluorescent film 460.

While the fluorescent lamp 46 is turned on, the lamp 46 generates heat, but since the lamp 46 itself is directly exposed to the outside, heat is directly emitted to the outside air.

In addition, the heat generated by the heat insulating air layer 32 formed in the closing member 24 may prevent heat generated by the fluorescent lamp 46 from being transferred to the cover 12.

Therefore, the components 360... 380... Of the high frequency lighting circuit 34 accommodated in the cover 12 are not damaged by the heat of the lamp 46.

However, such a fluorescent lamp unit 10 may be removed from the socket on the power supply side and installed on the mounting surface P such as the table floor.

Here, the position of the center G ₁ of the fluorescent lamp unit 10 is set toward the lamp 46 rather than the maximum diameter portion on the cover 12 side.

Therefore, the fluorescent lamp unit 10 is inclined toward the fluorescent lamp 46 as shown in FIG.

In addition, at the same time, the two surfaces of the maximum diameter portion of the cover 12 side, substantially the outer circumference portion of the cover plate 68, and the front end portion (curved in a U-shape) of the lamp 46 are installed at the same time (P). )

That is, the fluorescent lamp unit 10 is installed on the installation surface P with the center line 01-01 inclined.

A force is applied to this installation surface P in the direction of rolling the fluorescent lamp unit 10 (round circumferential direction of the cover 12).

Then, the part in contact with the mounting surface P of the lamp 46 becomes the tip portion m of the two U-shaped glass tubes 60a and 60b as shown in FIGS. 1 and 2 or rotates by 90 ° in this state. As shown in FIG. 6 and FIG. 7, it becomes either one of the front end portions n, n of one U-shaped glass tube 60a, 60b.

This is because the fluorescent lamp 46 has a structure in which two glass tubes 60a and 60b are attached together and joined together as described above.

That is, since the fluorescent lamp 46 is non-circular, the fluorescent lamp unit 10 is rolled to one of the postures shown in FIGS. 1 and 2 or the postures of FIGS. 6 and 7.

Therefore, the rolling fluctuation of the fluorescent lamp unit 10 is in a range of approximately 90 degrees.

Therefore, it does not roll off the table or the like from the installation surface (P), and as a result, it is possible to prevent damage to other objects.

In addition, when the fluorescent lamp unit 10 is rolled and forcedly applied from the outside, the position of the center G1 is set toward the lamp 46 rather than the cover 12, so that the maximum of the lamp unit 10 Two portions of the diameter portion and the tip portion of the lamp 46 smaller than the maximum diameter portion are brought into contact with the installation surface at the same time.

Therefore, the fluorescent lamp unit 10 is in a posture in which the center line 01-01 is inclined.

This moves in a constant area, such as when the cone rolls in contact with the surface of the installation.

Therefore, the rolling range of the unit 10 becomes small and it can prevent rolling to the far place.

As such, the position of the center G1 of the fluorescent lamp unit is set toward the curved fluorescent lamp 46 rather than the maximum diameter portion of the cover 12. Therefore, when the lamp unit is installed laterally on an installation surface such as a table, the cover ( At least two portions of the large diameter 12) and the tip portion m or n of the lamp 46 are in contact with the installation surface at the same time.

The curved fluorescent lamp 46 described above is non-circular in shape around the center line 01-01.

Therefore, when this lamp unit 10 contacts a mounting surface, since it is a non-circular shape, rolling away is prevented.

Therefore, the range of the cloud becomes small and the damage of the unit 10 can be prevented.

However, in order to set the center position of the entire fluorescent lamp unit toward the fluorescent lamp rather than the maximum diameter part of the cover, the following aspect is determined.

That is, as in the above-described first embodiment, the welding position of the circuit board to which the components of the high frequency lighting circuit are attached (in the above-described first embodiment, the components 360 and the board 40 of the starting circuit) is determined as the position of the lamp unit. Either do not overlap with the axial direction or lengthen the axial length of the lamp.

Alternatively, the maximum diameter of the cover is made larger than the maximum diameter of the cover plate so that the above-mentioned device is inclined toward the fluorescent lamp more when the lamp unit is installed on the mounting surface.

For example, FIG. 8 and FIG. 9 show an example in which the maximum diameter of the cover is made larger than the maximum diameter of the cover plate as the second embodiment of the present invention.

Here, the detailed descriptions of those indicated by the same reference numerals as those of the first embodiment described above will be omitted.

In FIG. 8 and FIG. 9, the fluorescent lamp unit 80 is provided laterally with respect to the mounting surface P, such as a table, and "82" is a synthetic resin cover.

The cover 82 is formed in a generally rice-shaped shape with a circular cross section, and at one end, a cylindrical portion 86 having a small diameter protrudes from the opening 84 at the other end, and a cylindrical portion 86 is provided. The metal 18 is deposited.

In the side wall of the cover 82, a vent hole 90... Which communicates the room 88 in the cover 82 with the outside is formed.

The opening 84 at the other end of the cover 82 described above has a maximum diameter and is attached to the opening 84 with a closing member 92 made of synthetic resin, for example.

The closing member 92 is composed of a pair of disk-shaped partition plates 94 and 28 spaced apart in the axial direction. The partition members 94 and 28 are connected to the connecting ribs 30 interposed therebetween. Are opposed at predetermined intervals.

In addition, the diameter of the partition plate 94 and 28 is the same size as that of the opening in which the partition plate 64 closes the opening of the cover 82, so that the partition plate 28 is smaller than the partition plate 94. have.

Then, the insulating air layer 32 is formed between the two opposing partition plates 94 and 28 apart from each other so as to communicate with the outside over the entire circumference of the partition plates 26 and 28.

In the disk-shaped partition plate 94 of one closure member 84, an edge wall 96 into which the opening of the cover 82 is fitted is formed.

The closing member 84 is attached to the cover 82 by using a device such as adhesive or caulking or engagement with the opening 84 of the cover 82 being covered with the edge wall 96 to be fitted. It is fixed.

Thus, the room 88 partitioned from the outside by the closing member 84 is comprised in the cover 82.

The room 88 in the cover 82 is accommodated in each component of the high frequency lighting circuit 34.

Since the inside of room 88 is the same as that of 1st Embodiment mentioned above, description is abbreviate | omitted.

A curved fluorescent lamp 46 is attached to the disk-shaped partition plate 28 on the other side of the closing member 92.

Since the configuration of the curved fluorescent lamp 46 is the same as that of the first embodiment described above, the description is omitted here.

In the fluorescent lamp unit 80 configured as described above, the center of the whole apparatus is G ₂ .

Then, this center G2 is set toward the fluorescent lamp 46 rather than the maximum diameter of the cover 82 in the axial direction (center line 02-02 direction) of the unit 80.

This center G2 moves and attaches the circuit board 40 and the starting circuit component 360... Of the high frequency lighting circuit 34 in the direction of the opening 84 of the cover 82 as in the first embodiment. Thus, the position is the same as that of FIG.

The fluorescent lamp unit 80 is used by sandwiching the clasp 18 into a socket (not shown) on the power supply side, but is removed from the socket and is provided laterally on an installation surface P such as a table and a floor. .

Here, the position of the center G2 of the lamp unit 80 is set toward the lamp 46 rather than the maximum diameter portion on the cover 82 side.

In the center line of the closure member fluorescent lamp unit 80 for installation on the surface (P), so the diameter of 92, a disk-shaped partition plate 92 made of a larger than the diameter of the disk-shaped partition plate 28 (0 _{2-0 2} ) The inclination of ₂ becomes large.

Therefore, as shown in Fig. 8, the largest diameter portion on the cover 82 side, in fact, two places between the outer circumference portion of the disc partition plate 94 and the tip portion (curved in a U-shape) of the lamp 46 At the same time, it is installed on the mounting surface P.

Therefore, the fluorescent lamp unit 80 is provided on the center line surface installation (0 ₂ -0 ₂₎ energy position (P).

As a result, when a force is applied in the direction of rolling the fluorescent lamp unit 80 on the mounting surface P (round circumferential direction of the cover 82), it contacts with the mounting surface P of the lamp 46 as in the first embodiment. The part to be becomes the tip part m (m) of two U-shaped glass tubes 60a, 60b like FIG. 8, and FIG. 9, or turns into 90 degrees in this state.

That is, since the fluorescent lamp 46 is non-circular, the rolling angle of the fluorescent lamp unit 80 becomes about 90 ° and the rolling range is extremely small, even when the cylindrical tube lamp unit 80 is rolled. .

Therefore, it is prevented from rolling off the installation surface (P) and falling from the table, etc., and colliding with another object to be broken.

In addition, when the fluorescent lamp unit 80 is forcibly rolled by applying force from the outside, the lamp unit 80 has a larger diameter than that of the disc diaphragm 94 and the disc diaphragm 94. The two ends of the small lamp 46 contact the mounting surface at the same time.

Therefore, the fluorescent lamp unit 80, the center line (0 ₂ -0 ₂₎ is sa inclined posture.

This may for example be greater than the inclination angle of the center line of the lamp unit 10 of the first embodiment (0 ₂ -0 _2).

In addition, since the cone moves in a constant area in the same manner as rolling the quadrilateral in contact with the installation surface, the rolling range is smaller than in the first embodiment, and it can be prevented from rolling far.

In the third embodiment, an example in which the fluorescent lamp 46 is moved away from the cover 12 to move the center G3 will be described.

In addition, since it is the same as that of the 1st and 2nd embodiment mentioned above, operation is abbreviate | omitted and only a structure is demonstrated and detailed description is abbreviate | omitted about the thing shown with the same reference number.

10 and 11, since the fluorescent lamp unit 100 is provided laterally with respect to the mounting surface P, such as a table, the room 20 is comprised in the synthetic resin cover 12. As shown in FIG.

The opening 14 of the cover 12 described above is the maximum diameter, and the closing member 102 made of, for example, synthetic resin is attached to the opening 14.

That is, the opening part 14 of the cover 12 mentioned above is closed by this closing member 102. FIG.

The closing member 24 is constituted by a pair of disk-shaped partition plates 26 and 28 spaced apart in the axial direction, and the partition members 26 and 28 are connected ribs 104. Are opposed at predetermined intervals.

Accordingly, the insulating air layer 32 is formed between the two partitioning plates 26 and 28 facing each other apart from each other so as to be connected to the outside through the entire circumference thereof.

In one of the disk-shaped partition plates 26, a circumferential wall 34 into which the openings 14 of the cover 12 are fitted is formed.

In a state where the opening 14 of the cover 12 is covered with the circumferential wall 34 to be fitted, the closing member 24 is covered with a cover (eg, adhesive, caulking, or engagement). 12) is fixed.

In this way, the room 20 partitioned outwardly by the closing member 24 is constituted in the cover 12. However, the inside of the room 20 is the same as that of the first embodiment described above, and thus description thereof is omitted.

Further, a circular fixing plate 106 is formed so as to fix both ends of the glass tubes 60a and 60b of the fluorescent lamp 46 which is curved on the opposite side to the disk-shaped partition plate 26 of the connecting rib 104 of the blocking member 24. Is installed.

That is, in this curved fluorescent lamp 46, both ends of each of the glass tubes 60a and 60b are fixed to the fixing plate 106 by the adhesive agent 6 6.

This fluorescent lamp (46) is in, because it is configured by joining the two glass tubes (60a) and (60b), has a circumference around the center line of the fluorescent lamp unit 100 (0. _{3-0. 3)} ratio, as described above It is circular.

In addition, the diameter of the lamp 46 is formed smaller than the maximum diameter in the opening part 14 of the cover 12. As a cross section of the fluorescent lamp 46, the place bonded to the adhesive 66 described above is covered with a cover plate 108 having a shape shown as a synthetic resin formed on the lower side.

That is, the above-mentioned glued place cannot be seen from the outside.

The cover plate 108 described above is fixed to the disk-shaped partition plate 28 and the fixing plate 106 by a method such as adhesive or fitting.

In addition, the cover plate 108 includes a concealed plate portion 110a so as to face the fusion portion 62 joined to each other at each end of the two glass tubes 60a and 60b so as to cover the fusion portion 62 from the outside. And 110b are protrudingly installed.

In the fluorescent lamp unit 100 configured in this way, the center of the whole unit is set to G3.

Then, the center line (G ₃₎ are installed towards the fluorescent lamp (46) than the maximum diameter portion of the cover 12 in the (axial center line (0. _{3-0. 3)} of the unit (100).

In addition, since the fixing position of the fluorescent lamp 46 (the upper side of the fixing plate 106) is set toward the lamp more than in the first embodiment, the position of the center G ₃ in FIG. 10 is further deviated toward the lamp.
