Description

  The present invention relates to an electrodeless discharge lamp device, and more particularly to a structure for attaching the electrodeless discharge lamp to a base member.

  For example, the configuration of a conventional electrodeless discharge lamp device 100 described in Patent Document 1 is shown in FIG. A conventional electrodeless discharge lamp device 100 includes an electrodeless discharge lamp 110 (hereinafter abbreviated as a lamp 110) in which an interior 111 is filled with a discharge gas, a base member 120 mounted on a lighting fixture or the like, and a high-frequency magnetic field. A power coupler 130 is provided. The lamp 110 is made of a light-transmitting material such as glass and is rotationally symmetric about the axis L. The lamp 110 has a substantially spherical shape on the outside and a substantially cylindrical stem 112 on the inside. The power coupler 130 includes a substantially cylindrical core 131, an induction coil 132 wound around the top of the core 131, and the like, and is fitted inside the stem 112. The power coupler 130 has a base portion 133 fixed to the base member 120, and an intermediate member 121 is fitted to the base member 120 so as to cover the base portion 133. The lower end 113 of the lamp 110 is fixed to the inner flange 141 at the top of the cylindrical base 140 with an adhesive 125. The base 140 has a lower end 142 fixed to the intermediate member 121. An electric wire 135 for supplying high-frequency power to the induction coil 132 of the power coupler 130 is drawn out of the base 140 from an opening 143 provided in the lower end 142 of the base 140.

  In the conventional electrodeless discharge lamp device 100, the electric wire 135 drawn out from the base 140 is exposed to light emitted from the lamp 110. Since the light emitted from the lamp 110 includes ultraviolet rays, the exposure of the ultraviolet rays promotes the deterioration of the resin that is the material for the insulating coating of the electric wires 135. Of the electric wire 135, particularly in the vicinity of the portion pulled out from the base 140 is highly likely to be bent at a steep angle and is inherently susceptible to bending stress. Therefore, there is a possibility that the insulation coating is significantly deteriorated by the exposure to ultraviolet rays. As a result, the life of the electrodeless discharge lamp device 100 itself may be shortened due to deterioration of the insulating coating of the electric wire 135. Or, due to the dielectric breakdown of the electric wire 135, the circuit may be short-circuited.

  Further, in the conventional electrodeless discharge lamp apparatus 100, the lamp 110 is fixed to the base 140, the base 140 is fixed to the intermediate member 121, and the intermediate member 121 is fitted to the base member 120. Therefore, for example, if vibration is applied to the lighting fixture on which the electrodeless discharge lamp device 100 is mounted, the vibration is transmitted to the lamp 110 via the base member 120, the intermediate member 121, and the base 140. On the other hand, the vibration is transmitted to the power coupler 130 only through the base member 120. Therefore, the lamp 110 and the power coupler 130 may vibrate at different phases. In particular, when the elastic deformation of the adhesive 125 that fixes the lamp 110 and the base 140 is large, there is play due to the fitting gap between the fixing part of the base 140 and the intermediate member 121 and the fitting part of the intermediate member 121 and the base member 120. If so, the lamp 110 and the power coupler 130 may even vibrate in opposite phases. Furthermore, the electrodeless discharge lamp device 100 is designed to narrow the gap between the stem 112 and the induction coil 132 of the power coupler 130 in order to increase the luminous efficiency. Therefore, when the vibration as described above is applied, the induction coil 132 of the power coupler 130 and the stem 112 come into contact with each other, and the lamp 110 (particularly the stem 112 portion) is damaged. It becomes.

The above problem is not unique to the electrodeless discharge lamp apparatus in which the induction coil as shown in FIG. 8 is arranged inside the lamp. For example, the induction coil described in Patent Document 2 This also applies to electrodeless discharge lamp devices arranged on the outside.
Japanese National Patent Publication No. 11-508404 (FIG. 1) Japanese Patent Laid-Open No. 8-20385 (FIG. 1)

  The present invention has been made to solve the above-described problem, and an electrodeless discharge lamp capable of preventing damage due to contact between an induction coil of a power coupler and a valve stem even when vibration is applied. An object is to provide an apparatus.

In order to achieve the above object, the invention of claim 1 is an electrodeless discharge lamp device, which is formed of a translucent material in a substantially rotationally symmetric shape about a predetermined axis, and a discharge gas is enclosed therein. An electrodeless discharge lamp, a high frequency magnetic field generating means that is provided in the vicinity of the electrodeless discharge lamp and generates a high frequency magnetic field with respect to a discharge gas inside the electrodeless discharge lamp, and is attached to a lighting fixture, A base member that holds the high-frequency magnetic field generating means, a substantially cylindrical main body portion in which a neck portion of the electrodeless discharge lamp is fitted and fixed to a first end portion thereof, and a second end portion of the main body portion from the second end portion. A base having a flange portion formed so as to protrude outward in a direction orthogonal to the axis, abutting on a surface orthogonal to the axis of the base member or the intermediate member fixed to the base member, and fixed; High frequency Comprising a wire for supplying a high frequency power to the field generating means, the electric wire is led out from the inside of the cap through the base member side in the predetermined direction parallel to the axis of the flange portion of the ferrule The flange portion of the base protrudes outward from the base member in a direction orthogonal to the axis, and the electric wire extends outside the base member in the direction parallel to the predetermined axis of the flange portion. It is wired on the member side.

According to a second aspect of the present invention, in the electrodeless discharge lamp device according to the first aspect of the present invention, a wire drawing groove for drawing the electric wire from the inside of the base to the outside is provided in the base member. To do.

According to a third aspect of the present invention, in the electrodeless discharge lamp device according to the first or second aspect, in a cross section orthogonal to the axis, a part of a neck portion of the electrodeless discharge lamp is linearly formed on the axis. A concave portion is provided on the outer peripheral surface in the orthogonal direction, and a leaf spring-like protrusion that engages with the concave portion is provided on an inner peripheral surface substantially parallel to the shaft in the vicinity of the first end portion of the base. To do.

According to a fourth aspect of the present invention, in the electrodeless discharge lamp device according to any one of the first to third aspects, a reflective layer is formed on the outer surface of the neck portion of the electrodeless discharge lamp. And

According to the present invention, since the base for fixing the lamp to the base member or the intermediate member has the flange portion protruding outward in the direction orthogonal to the rotational symmetry axis of the lamp, the flange portion of the base And the surface perpendicular to the axis of the base member or the intermediate member are in close contact with each other at a place away from the axis. Therefore, the substantially cylindrical main body portion of the base is firmly fixed in parallel to the axis. As a result, the first end portion into which the neck portion of the lamp of the base is fitted hardly sways with respect to the base member or the intermediate member. Therefore, even when vibration is applied to the electrodeless discharge lamp device, the base is substantially integrated with the base member and vibrates in substantially the same phase. Further, since the neck portion of the lamp is fitted and fixed to the first end portion of the main body portion of the base, the phase difference between the vibration of the base and the lamp is small. On the other hand, since the high-frequency magnetic field generating means held by the base member is also firmly fixed to the base member, the high-frequency magnetic field generating means also vibrates in substantially the same phase as the base member. Therefore, the phase difference between the vibration of the lamp and the vibration of the high-frequency magnetic field generating means is very small, and there is almost no possibility that they vibrate in different phases, in particular, opposite phases, and the lamp and the high-frequency magnetic field generating means are in contact It is possible to prevent the lamp from being damaged. Also, since the drawer from the inside of the base of the wire through the bottom of the flange, and it is hardly irradiated with ultraviolet this part is emitted from the lamp. As a result, it is possible to protect a portion that is relatively susceptible to bending stress and originally deteriorates the insulation coating from further deterioration due to ultraviolet rays. As a result, the possibility of occurrence of a short circuit due to deterioration of the insulating coating is reduced, the life of the electrodeless discharge lamp device can be extended, and the reliability can be improved. Further, even after being pulled out of the base by the flange portion of the base, it becomes possible to protect the electric wire from ultraviolet rays within a certain range, and the reliability of the lighting device using this electrodeless discharge lighting device is improved. be able to.

(First embodiment)
The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an electrodeless discharge lamp apparatus 1 according to the first embodiment of the present invention. In the following description, the upper side of the drawing is “upper” and the lower side is “lower”.

  As shown in FIG. 1, an electrodeless discharge lamp device 1 according to a first embodiment includes a base member 10 attached to a lighting fixture or the like, and an electrodeless discharge lamp 20 (hereinafter referred to as “discharge electrode”) filled with a discharge gas. And a power coupler (high frequency magnetic field generating means) 30 for generating a high frequency magnetic field. The lamp 20 can be separated from the power coupler 30.

  The lamp 20 is made of a light-transmitting material such as glass and is rotationally symmetric about the axis L. The lamp 21 has a substantially spherical outer shape and a substantially truncated cone shape at the outer lower portion. Is formed of a substantially cylindrical stem 22 having a hollow portion 23 having a substantially circular cross section formed therein, and a neck portion 24 in which the valve 21 and the stem 22 are melted and brought into close contact with each other. For example, a vent pipe (not shown) is provided at the upper end of the stem 22 and is used for exhausting air from the internal space 25 of the lamp 20 and filling the internal space 25 with a discharge gas such as mercury or a rare gas. A fluorescent material is applied to the inner surface 26 of the bulb 21. The lamp 20 is fixed to the base member 10 via a base 50 described later.

  The power coupler 30 includes a cylindrical heat dissipation cylinder 31, a cylindrical ferrite core 32 fitted on the upper end side of the heat dissipation cylinder 31, an induction coil 33 wound around the outer periphery of the ferrite core 32, and the like. ing. Each part of the power coupler 30 has a substantially annular cross section, and its outer diameter is set to be approximately equal to the inner diameter of the hollow part 23 of the stem 22 and slightly smaller than that. Thereby, the power coupler 30 can be fitted into the hollow portion 23 of the stem 22. The power coupler 30 is directly fixed to the base member 10.

  When high frequency power is supplied to the induction coil 33, a high frequency magnetic field is generated from the induction coil 33. The discharge gas filled in the lamp 20 is excited by receiving the energy of the high frequency magnetic field, discharges, and emits ultraviolet rays. The emitted ultraviolet light is converted into visible light by the fluorescent material applied to the inner surface 26 of the bulb 21. Since the electrodeless discharge lamp does not have an electrode inside the bulb, there is no non-lighting due to electrode breakage, and the life is longer than that of a general fluorescent lamp.

  The base member 10 has a disk shape made of, for example, an insulating resin, and has an attachment structure 11 for attaching to a lighting fixture or the like at the bottom. The heat radiation cylinder 31 of the power coupler 30 may be fixed integrally with the base member 10 by insert molding, for example, or may be fixed by an adhesive. A hook 12 for fixing the base 50 is provided on the upper surface of the base member 10.

  The base 50 is formed of, for example, resin, metal, or the like, and symmetrically with respect to the axis L so as to protrude outward from the substantially cylindrical main body 51 and the lower end (second end) of the main body 51. It has at least one pair of flange portions 52 formed. The flange portion 52 is provided with an opening 53 for engaging with the hook 12. For example, as shown in FIG. 1, the hook 12 protrudes from the upper surface of the base member 10 and is formed so that the width or thickness of the top portion (hook portion) is wider than the width or thickness of the base portion. Yes. The opening 53 is, for example, a rectangular opening, and its length and width are slightly larger than the width and thickness of the portion near the base of the hook 12 and longer than the width and thickness of the portion having the maximum width of the hook 12. The height and / or width is set to be slightly narrower. When the base 50 is fixed to the base member 10, the hook 12 is press-fitted into the opening 53 using elastic deformation of resin. As a result, the base 50 is tightly fixed to the base member 10 without a gap.

  The inner diameter of the upper end (first end) of the main body 51 of the base 50 is formed to be slightly larger than the outer diameter of the neck 24 at the lower end of the lamp 20. The neck portion 24 of the lamp 20 is fitted to the main body portion 51 of the base 50 by a predetermined length and is fixed by an adhesive 55.

  An electric wire 35 for supplying high-frequency power to the induction coil 33 of the power coupler 30 passes through the wire lead-out groove 13 for passing the electric wire 35 provided in the base member 10 from the inside of the base 50, for example. It is pulled out from the bottom. In particular, by forming the wire lead-out groove 13 immediately below the place where the flange portion 52 of the base 50 is located, the ultraviolet rays emitted from the lamp 20 can be blocked by the flange portion 52. Therefore, it is possible to prevent the insulating coating from being further deteriorated by ultraviolet rays at a portion where the deterioration of the insulating coating is originally progressed by bending stress, such as a portion where the electric wire 35 is bent at a steep angle. Note that a reflection layer is formed on the outer surface of the neck portion 24 of the lamp 20 to reflect upward the light emitted from the lamp 20 downward in the figure. Therefore, almost no light from the lamp 20 reaches the inside of the main body 51 of the base 50, and the electric wire 35 inside the base 50 is not exposed to ultraviolet rays. On the other hand, deterioration of the insulating coating due to ultraviolet rays can be prevented.

  In the electrodeless discharge lamp device 1 according to the first embodiment configured as described above, the lamp 20 is fixed to the base 50, and the base 50 is closely fixed to the base member 10 by the flange portion 52. Therefore, if vibration is applied to the luminaire on which the electrodeless discharge lamp device 1 is mounted, the vibration is transmitted to the lamp 20 via the base member 10 and the base 50. On the other hand, the vibration is transmitted to the power coupler 30 via the base member 10. However, since the base 50 is tightly fixed to the upper surface of the base member 10 by the flange portion 52 protruding outward from the lower end of the cylindrical main body portion 51, the main body portion 51 of the base 50 is substantially the base member. 10 is integrated. Therefore, the main body 51 of the base 50 vibrates with substantially the same phase as the vibration phase of the base member 10. Similarly, since the power coupler 30 is also substantially integrated with the base member 10 by insert molding or the like, the power coupler 30 also vibrates in substantially the same phase as the base member 10. Accordingly, it is considered that the power coupler 30 and the base 50 also vibrate with substantially the same phase. Further, since the base 50 and the neck portion 24 of the lamp 20 are fixed so as to be fitted to a predetermined length, the base 50 and the lamp 20 also vibrate in a slightly different phase due to the elasticity of the adhesive, but a very large position. There is no phase difference. For this reason, the lamp 20 and the power coupler 30 vibrate substantially in the same phase, and even if there is a phase difference, there is no great difference. Therefore, there is almost no possibility that the two will vibrate in different phases, particularly in the opposite phase. It is possible to prevent the lamp 20 (particularly the stem 22 portion) from being damaged due to the induction coil 33 and the stem 22 coming into contact with each other.

  The above-described effect can be obtained if at least one pair of the flange portions 52 of the base 50 are provided symmetrically with respect to the axis L. However, the flange portions 52 are not necessarily provided symmetrically with respect to the axis L. For example, it may be provided at three or more locations at a predetermined angle. In other words, two or more flange portions 52 of the base 50 need only be provided around the axis L at approximately equal intervals. Alternatively, an annular flange may be formed over the entire circumference of the main body 51 of the base 50. Further, instead of the base fixing structure by the hook 12 provided on the upper surface of the base member 10 and the opening 53 provided in the flange portion of the base 50, a screw is inserted from the opening provided in the flange portion 52 to directly connect the base. 50 may be screwed to the base member 10. Similarly, the base fixing structure by the hook 12 and the opening 53 may be provided at two or more locations around the axis L at substantially equal intervals.

(Second Embodiment)
Next, the structure of the electrodeless discharge lamp device 1 according to the second embodiment of the present invention is shown in FIG. In the first embodiment, the flange portion 52 of the base 50 is directly fixed to the upper surface of the base member 10. However, in the second embodiment, the flange portion 52 of the base 50 is connected to the intermediate member 40. It is fixed to the base member 10 via A plurality of downwardly projecting claws 54 are formed on the bottom surface of the flange portion 52 of the base 50, and as shown in FIG. 3, engaging grooves 41 having different widths that engage with the claws 54 on the upper surface of the intermediate member 40. The so-called bayonet mount structure is formed. In the example shown in FIG. 2, the flange portion 52 is formed over the entire periphery of the lower end of the main body of the base 50.

  As shown in FIG. 3, the engaging groove 41 has a narrow first groove portion 42 through which a portion (hook portion) having the maximum dimension of the claw 54 penetrates and a portion near the root of the claw 54. A second groove 43. Further, the second groove 43 is formed with a stopper 44 for preventing the claw 54 engaged with one end from being inadvertently dropped. When the claw 54 is engaged with the second groove portion 43, the claw 54 gets over the stopper 44 by utilizing the elastic deformation of itself and / or the stopper 44.

  In order to fix the base 50 to the intermediate member 40, the base 50 is inserted in a state where the claw 54 is passed through the wide first groove 42 of the engaging groove 41 and the flange portion 52 is in contact with the upper surface of the intermediate member 40. Is rotated about axis L. Then, the claw 54 relatively moves from the wide first groove portion 42 toward the narrow second groove portion 43. At that time, it gets over the stopper 44 and reaches the second groove 43. The width of the second groove portion 43 of the engagement groove 41 is substantially the same as the thickness near the base of the claw 54 and is set in a state where there is almost no gap in the engagement state. As a result, the base 50 is tightly fixed to the intermediate member 40 without a gap. Since the intermediate member 40 is firmly fixed to the base member 10 by the same bayonet mounting structure or screwing, the base 50 is also firmly fixed to the base member 10 with almost no backlash. The

  In the electrodeless discharge lamp device 1 according to the second embodiment configured as described above, the lamp 20 is fixed to the base 50, and the base 50 is in close contact with the base member 10 via the intermediate member 40 by the flange portion 52. It is fixed. Therefore, if vibration is applied to the luminaire on which the electrodeless discharge lamp device 1 is mounted, the vibration is transmitted to the lamp 20 via the base member 10, the intermediate member 40 and the base 50. On the other hand, the vibration is transmitted to the power coupler 30 via the base member 10. Therefore, there is a possibility that the vibration of the lamp 20 and the phase difference of the power coupler 30 are slightly larger than in the case of the first embodiment. However, in order to remove the base 50, it is necessary to rotate it around the axis L and to get the stopper 44 over the claw 54. Therefore, even when an impact is applied to the electrodeless discharge lamp device 1, the possibility that the base 50 falls off from the base member 10 or the intermediate member 40 can be greatly reduced.

  In the second embodiment, the engaging groove 41 is provided in the intermediate member 40 in consideration of the moldability when molding the engaging groove 41 by resin injection molding, the mold cost, etc. The member 40 may be omitted, and the engaging groove may be formed directly in the base member 10. Alternatively, the claw 54 of the base 50 may be engaged with the engaging groove provided in the base member 10 while the intermediate member 40 is interposed between the base 50 and the base member 10.

(Third embodiment)
Next, the structure of the electrodeless discharge lamp device 1 according to the third embodiment of the present invention is shown in FIG. In the third embodiment, an engagement structure is provided in the vicinity of the upper end of the neck portion 24 of the lamp 20 and the main body portion 51 of the base 50 so that the lamp 20 is not easily dropped from the base 50 in the axis L direction. . Other points. Since this is basically the same as the case of the first embodiment, differences will be described.

  As shown in FIG. 4, a stopper 56 protruding inward is formed in the vicinity of the upper end of the inner peripheral surface of the main body 51 of the base 50. The neck portion 24 of the lamp 20 is also formed with a recess 27 that is engaged with the stopper 56. Details of the engaging portion between the lamp 20 and the base 50 are shown in FIG. As described above, the lamp 20 is formed to be rotationally symmetric with respect to the axis L, so that the cross section in the direction orthogonal to the axis L is basically circular. However, as shown in FIG. 5, the concave portion 27 is formed by linearly deforming a part of the substantially circular cross section at a plurality of locations (four locations in the figure). Further, a leaf spring-like protrusion is formed as a stopper 56 on the inner peripheral surface of the main body 51 of the base 50 so that the width direction thereof is parallel to the axis L. The shape of the stopper 56 is not limited to this, and may be other shapes as long as it can be elastically deformed.

  With such a configuration, the stopper 56 is easily elastically deformed in the direction orthogonal to the axis L, but is difficult to deform in the direction parallel to the axis L. Since the lower end of the neck portion 24 of the lamp 20 is formed into a curved surface with a relatively large radius, the stopper 56 is deformed with a relatively small force when the neck portion 24 is fitted to the main body portion 51 of the base 50. Can be made. On the other hand, the end surface of the concave portion 27 formed in the neck portion 24 is formed in a curved surface with a much smaller radius than the lower end of the neck portion 24, so that a large force should not be applied to destroy the stopper 56. The neck portion 24 cannot be pulled out from the base 50. As a result, even when an impact is applied in the direction of the axis L, the possibility that the lamp 20 falls off the base 50 can be greatly reduced. Further, after the neck portion 24 of the lamp 20 is fitted to the main body portion 51 of the base 50, an adhesive is injected into the gap between the concave portion 27 and the inner peripheral surface of the main body portion 51 to fix the lamp 20 and the base 50. May be.

  FIG. 6 shows another configuration example of the electrodeless discharge lamp device 1 according to the third embodiment. As shown in FIG. 6, an annular groove is formed as the recess 27 over the entire circumference of the neck portion 24 of the lamp 20. In the configuration example shown in FIG. 5, the neck portion 24 of the lamp 20 cannot be fitted to the main body portion 51 of the base 50 unless the concave portion 27 and the stopper 56 are aligned to some extent. On the other hand, in the configuration example shown in FIG. 6, the concave portion 27 must be formed on the entire circumference of the neck portion 24, but alignment of the concave portion 27 and the stopper 56 is not necessary. Moreover, you may form an annular convex part over the perimeter of the internal peripheral surface of the main-body part 51 of the nozzle | cap | die 50 as the stopper 56. As shown in FIG. In that case, the structure of a mold for forming the die 50 can be simplified.

(Other variations)
The present invention is not limited to the configurations described in the above embodiments, and various modifications can be made. For example, as shown in FIG. 7, the flange portion 52 of the base 50 may be formed so as to protrude further outward than the outermost peripheral portion of the base member 10, and the electric wire 35 may be disposed thereunder. In that case, the insulating coating of the electric wire 35 can be protected from the ultraviolet rays contained in the light irradiated downward from the lamp 20, and a short circuit due to deterioration of the insulating coating can be prevented. Alternatively, in the second embodiment, a concave portion may be provided in the neck portion 24 of the lamp 20, and a stopper may be provided on the inner peripheral surface of the main body portion 51 of the base 50. Thereby, similarly to the case of the third embodiment, even when an impact in the direction of the axis L is applied, it is possible to reduce the possibility that the lamp 20 falls off the base 50. Furthermore, it goes without saying that the present invention can also be applied to an electrodeless discharge lamp apparatus using an electrodeless discharge lamp of the type in which a vent tube for venting air and filling a discharge gas is provided at the center of the stem 22.
