Description

  The present invention relates to an illuminating lamp (lamp) using a light emitting element such as an LED (light emitting diode) as a light source.

  An LED (light emitting diode), which is a typical example of a light emitting element, has lower power consumption and superior durability than incandescent bulbs and fluorescent lamps, and is characterized by being able to realize a variety of colors. In recent years, therefore, many illuminating lamps using LEDs have been proposed. For example, Patent Documents 1 and 2 describe an LED illumination lamp that can be used by connecting to a socket portion of a fluorescent lamp fixture as an alternative to a conventional fluorescent lamp. In both Patent Documents 1 and 2, one elongated substrate on which a plurality of LEDs are mounted along the longitudinal direction is disposed inside the elongated cylindrical pipe (cover).

  And in patent document 1, while two terminals for electricity supply are provided in the both ends of a board | substrate, the base cap is engage | inserted in the both ends of a cylindrical pipe, and the front-end | tip of the said terminal is outward from a base cap. It protrudes to the side and is configured to be inserted into the socket part of the fluorescent lamp fixture.

  On the other hand, in Patent Document 2, a plurality of resin clips are arranged on the inner peripheral portion of the cylindrical pipe with appropriate intervals in the longitudinal direction. Although there is no detailed explanation, in the drawing, clips are arranged at a total of three locations in the vicinity of the both ends in the longitudinal direction of the substrate and in the center, and the leading end of each clip is penetrated (inserted) into the substrate, and the clips are inserted. The substrate is supported by a cylindrical pipe.

Japanese Patent Laid-Open No. 2001-351402 (particularly FIGS. 3 and 6) JP 2007-12322 A (particularly FIGS. 1 and 3)

  In an illuminating lamp that replaces a fluorescent lamp, the substrate on which the LED is mounted is formed in an elongated strip shape (long) in accordance with an elongated cylindrical pipe. In addition, it is difficult to stably support the substrate because the distance between the support portions becomes long simply by supporting the center. Therefore, if the external force (such as an impact or an earthquake due to a drop) is received during installation after the lighting lamp is transported, the board will be greatly bent, and if it is severe, the conductor (or wiring pattern) may be broken or the board may be damaged. There is a risk of problems such as these.

  Regarding this point, it is considered that the number of clips described in Patent Document 2 may be increased to support the substrate at a number of locations along the longitudinal direction. However, after inserting a long substrate into the inside of the end of the elongated cylindrical pipe, it is extremely troublesome to fit the substrate into the clip while preventing the LED from being damaged in a narrow space away from the end of the cylindrical pipe. There is a problem that the assembly work takes much time.

  The present invention has been made mainly for the purpose of improving such a current situation. Now, since the LED is a point light source, there is a problem in that when the LED is applied to a fluorescent lamp-type long and narrow illumination lamp, the LED looks poppy and gives a strange feeling to a person. The inventors of the present application have also made some improvements such as lighting without any sense of incongruity starting from the above improvement of the present situation, and these improvements are also disclosed in the specification and drawings.

  The present invention is specified as claims 1-6. Among these, the illuminating lamp according to the invention of claim 1 has, as a basic configuration, at least a substrate integrally extending long or intermittently extending, a light emitting element provided on one or both sides of the substrate, and at least the substrate. And a cylindrical or groove-shaped elongated cover member (cover means) covering from the light emitting element side.

  The cover member is a molded product, and at least part of the cover member has a light-transmitting property so that light from the light-emitting element can pass therethrough. The fitting part into which the edge fits directly is formed so as to extend along the longitudinal direction, or the fitting part into which the longitudinal side edge of the holding member holding the substrate fits along the longitudinal direction. The board is formed so as to extend in the width direction and the thickness direction so as not to be displaced by the fitting portion. In this case, the fitting portion may extend in series, or may intermittently extend.

  According to a second aspect of the present invention, the first aspect of the present invention is preferably embodied. In the first aspect of the present invention, the light diffusion element for diffusing light of the light emitting element is provided between the cover member and the substrate. Alternatively, a reflector that reflects light is provided. In this case, the diffusion portion may be integrated with the cover member or may be a separate body. Further, it is sufficient that at least one of the diffusing portion and the reflector is provided.

  A third aspect of the present invention is an embodiment of the first or second aspect. In the present invention, the cover member is an extruded product of a synthetic resin, and extends substantially linearly. The joint portion is a fitting groove extending from one end to the other end in the longitudinal direction of the cover member.

  The invention of claim 4 also embodies claim 1 or 2, and in claim 1, the cover member comprises a first cover body that covers the substrate from one surface side and the other surface. The second cover body that covers from the side is overlapped, and the fitting portion is formed at a portion where the first cover body and the second cover body overlap.

  The invention of claim 5 is made by an approach different from those of claims 1 to 4. In other words, the present invention is an elongated shape having one end surface and the other end surface, and the light incident on the end surface changes its direction and emits from a part or all of the circumferential direction of the outer peripheral surface. A light body, and end members fixed (arranged) to one end surface and the other end surface of the light guide, respectively, and one or both of the end members are connected to the light guide. A light-emitting element that emits light is provided.

  According to the first aspect of the present invention, the both longitudinal edges of the substrate or the holding member are fitted into the fitting portions of the cover member, so that the substrate is supported by the cover member in a wide range even if the substrate is in an elongated shape. Therefore, the substrate is held in a state in which bending is prevented or suppressed. Therefore, even when an external force is applied during transportation or in use, it is possible to prevent or remarkably suppress a problem that the substrate is damaged or the conductive wire is disconnected.

  Further, since the cover member is a molded product and can be manufactured with the fitting portion provided, it is not necessary to separately process the cover member to provide the fitting portion, thereby reducing the manufacturing cost. be able to.

According to the invention of claim 2, even if the light emitting element is in the form of a point light source, the light from each light emitting element is scattered by being transmitted through the diffusing part or diffusely reflected by the reflector, thereby transmitting the light transmitting surface of the cover member. Surface light can be emitted throughout. As a result, an uncomfortable lighting state in which the presence of the light source cannot be visually recognized is realized, and the use as a substitute for the conventional fluorescent lamp can be promoted.

  In this case, if the diffusing portion is provided integrally with the cover member, there is an advantage that it is not necessary to manage the diffusing portion as a member, and the assembly cost can be reduced. On the other hand, when the diffusing portion is provided separately on the cover member, an optimal material and manufacturing method for the diffusing portion can be selected without being limited by the material and molding method of the cover member.

  According to the invention described in claim 3, since the cover member is manufactured by extrusion molding, it is easy to form the cover member in a straight line, and the fitting groove is formed over the entire length of the cover member. Can be easily formed. In the first aspect, the fitting portion can be formed in a jumping manner. In the third aspect, since the fitting groove can be formed over the entire length of the cover member, the support stability of the substrate can be remarkably improved.

  In addition, since the cover member is an extrusion molded product, it is possible to easily mass-produce the cover member by manufacturing an intermediate product that is many times longer than the cover member and cutting it into a desired length, so that the manufacturing cost It is also possible to reduce this. Furthermore, since the intermediate product can be cut to an arbitrary length, the cost reduction effect is strongly exerted when a plurality of types of illumination lamps having different cover member lengths are manufactured.

  Furthermore, since the fitting groove extends from one end to the other end in the longitudinal direction of the cover member, the work of attaching the substrate to the cover member is an extremely simple operation of inserting the substrate into the fitting groove from one end or the other end. Therefore, the assembly of the illumination lamp can be performed very easily even if the cover member and the substrate are both long.

  According to invention of Claim 4, a cover member is comprised by overlapping the 1st cover body which covers a board | substrate from the one surface side, and the 2nd cover body which covers a board | substrate from the other surface side. Therefore, the cover member can be formed not only in the case of a linear shape but also in a non-linear type such as an annular shape. In addition, since the fitting portion is formed in the overlapping portion of the first and second cover bodies, when the first and second cover bodies are overlapped, the board can be sandwiched and attached, and the board can be easily attached. And can stably hold the substrate.

  In the invention according to claim 4, it is also possible to change the characteristics such as the material, color, transparency and the like of the first cover body and the second cover body, and thereby various designs can be realized.

  In the invention according to claim 5, although the light emitting element is arranged on the end face portion of the light guide, the direction of the light of the light emitting element is changed inside the elongated light guide. Light can be emitted from a part or all of the outer circumferential surface in the circumferential direction to emit light from the outer circumferential surface of the elongated light guide.

  Since the light emitting element is merely disposed on the end member of the end face of the light guide, the light emitting element is firmly held at the end face of the light guide even if the light guide (illumination lamp) is elongated. In addition, it can be easily attached. Therefore, it is possible to provide a light-emitting element type illumination lamp that is excellent in strength and easy to assemble with an appearance similar to a fluorescent lamp.

  Embodiments in which the present invention is embodied will be described below with reference to the drawings. In the following description, the light emitting element type illumination lamp is simply referred to as “illumination lamp”.

(1). First embodiment (FIGS. 1 to 3)
An illuminating lamp 1 according to the present embodiment is used as a lamp of an illuminating device 2 installed on a ceiling surface, a wall surface, or the like, and has an elongated shape as a whole (for convenience, the longitudinal direction is taken as the X-axis direction). explain.).

  The illuminating device 2 is provided with a pair of socket parts 3 and 4 for attaching the illuminating lamp 1, and the illuminating lamp 1 is held by the socket parts 3 and 4 so as not to fall off. As shown in FIG. 1 (a), one socket 3 is rotatable in the direction of approaching and separating from the other socket 4 with the base 2a side of the lighting device 2 as a base end (rotation fulcrum). The other socket part 4 is being fixed to the base 2a with respect to being provided. Therefore, one socket part 3 is rotated in the direction away from the other socket part 4, and one end in the longitudinal direction of the illuminating lamp 1 is fitted into the other socket part 4, and then the one socket part 3 is inserted into the other socket part. The illuminating lamp 1 is attached to the illuminating device 2 by fitting into the other end of the illuminating lamp 1 while returning to the direction close to the portion 4.

  1A shows a state in which the illuminating lamp 1 is positioned above the base 2a of the illuminating device 2, but when the illuminating device 2 is installed on the ceiling or the like, the upside down is reversed. In the case of installation on a wall surface, it becomes a vertically long posture.

  The illuminating lamp 1 includes a light source unit 13 and a cover member 10 that covers the light source unit 13. The light source unit 13 has a configuration in which a plurality of LEDs (light emitting diodes) 12 as light emitting elements are mounted on one side of a belt-like circuit board 11, and this is the inner side of an elongated synthetic resin cover member 10. Has been inserted. The circuit board 11 corresponds to the board recited in the claims.

  The LED 12 may adopt a multicolor light emission method including chips of red, green, and blue which are the three primary colors, or may adopt a single color light emission method such as a white light emitting diode. The light-emitting element can be appropriately changed depending on the application, and a light-emitting element of a different system from the LED (for example, an organic EL or a semiconductor laser) can be used.

  As shown in FIG. 1B, the cover member 10 includes a main cover body 10a having a cross-sectional shape viewed from the longitudinal direction formed in a downward U-shape (groove shape, bowl shape, channel shape), and the main cover. It consists of a substantially plate-like auxiliary cover body 10b that is fitted and fixed (adhered) to the opening on the opposite side of the U-shaped curved surface portion 15 in the body 10a, and has a tubular shape as a whole. ing. Since the main cover body 10a has a U-shaped cross section, it has a curved surface portion 15. In addition, only the main cover body 10a is displayed as a specific example of the cover member described in the claims, and the auxiliary cover body 10b may be referred to as a base member to which the cover member is attached.

  One end of the cover member 10 is covered with a first cap body 17, and the other end is covered with a second cap body 18. The cap bodies 17 and 18 are each fixed to the main cover body 10a with screws 19. A long groove 19a into which the screw 19 can be screwed extends in the main cover body 10a over the entire length (see FIGS. 1A and 1B).

  The first and second cap bodies 17 and 18 and the socket portions 3 and 4 are fitted to each other so that the LED 12 faces the side opposite to the base portion 2a with the illuminating lamp 1 attached to the lighting device 2. Irregularities for defining directionality are formed.

  The main cover body 10a, auxiliary cover body 10b, first cap body 17 and second cap body 18 are all made of synthetic resin, and the main cover body 10a and auxiliary cover body 10b use extruded products. Since the main cover body 10a needs to transmit the light of the LED 12, it is made of a resin having translucency, and milky white is preferable so that the LED 12 cannot be visually recognized from the outside. Needless to say, the LED 12 has a structure in which a diode chip is sealed with a translucent material.

  The auxiliary cover body 10b and the cap bodies 17 and 18 are formed of a resin that does not have translucency. Of course, these may also be formed of a translucent resin. Of course, it is also possible to manufacture the auxiliary cover body 10b and the cap bodies 17 and 18 with a translucent material. The auxiliary cover body 10b and the cap bodies 17 and 18 can be made of metal. When the auxiliary cover body 10b is made of metal, it is preferable to use an extruded product from the viewpoint of ease of processing and cost.

  The light source unit 13 has a configuration in which LEDs 12 are arranged on one side of an elongated circuit board 11 having a length slightly shorter than that of the cover member 10 with an appropriate interval. Each terminal of the LED 12 is connected to a wiring pattern (not shown) formed on the front surface or the back surface of the circuit board 11. A male connector 20 having a terminal 20a is attached to one end in the longitudinal direction of the circuit board 11, and a female connector 21 having a hole into which the terminal 20a is fitted is attached to the other end. The male connector 20 and the female connector 21 are electrically connected to each other. Since the LED 12 of the present embodiment is compatible with full color, the male connector 20 has four terminals 20a as shown in FIG.

The first cap body 17 at a position corresponding to the male connector 20 is formed with a hole portion into which the terminal 20a of the male connector 20 is fitted, and one socket portion 3 to be fitted into the first cap body 17; The male connector 20 is electrically connected. In this embodiment, the LED 12
Is set so as to be supplied only from one socket part 3 and the male connector 20 side, and therefore the electric power between the other socket part 4 and the female connector 21 is set. No connection is required.

  Therefore, when only one light source unit 13 is used, the installation of the female connector 21 located at the position facing the other socket portion 4 can be omitted. However, as will be described later, a plurality of light source units are used. When connecting 13, the female connector 21 is used for electrical connection with the male connector 20.

  As shown to Fig.1 (a), the illuminating device 2 is provided with the circuit part 14 for supplying electric power to LED12. The circuit unit 14 includes an AC / DC converter, a voltage control unit that adjusts the voltage to a value corresponding to the LED, and the like. These circuit units 14 are built in the base 2 a of the lighting device 2, but they can be reduced in size and built in one socket unit 3 or mounted on the back surface of the circuit board 11.

  Between the curved surface portion 15 of the main cover body 10 a and the light source unit 13 in the cover member 10, a sheet-like diffusion plate 25 as an example of a diffusion portion for diffusing the light emission of the LED 12 is provided in the light source unit 14. Are arranged so as to extend long with substantially the same length. The diffuser plate 25 is made of a resinous sheet-like body having a large number of fine irregularities formed on the front surface, back surface, or both front and back surfaces, and having translucency. The main cover body is viewed from the axial direction of the cover member 10. It is curved to be convex in the same direction as the curved surface portion 10a. The light emitted from each LED 12 is diffused and scattered by passing through the diffusion plate 25, whereby the light transmitting surface of the main cover body 10a can be surface-emitting substantially uniformly over the entire surface.

  Between the diffusion plate 25 and the circuit board 11, a sheet-like reflection plate 26 having a reflection surface for condensing and reflecting the light emission of the LED 12 toward the diffusion plate 25 is a light source unit. 14 so as to extend substantially the same length as 14. As shown in FIGS. 1B and 1C, the reflection plate 26 is provided in a shape in which the central portion in the width direction (Y-axis direction) is curved in a direction away from the diffusion plate 25 (that is, in the axial direction). The tip of the LED 12 protrudes from the through hole 27 provided in the reflection plate 26 toward the curved surface portion 15 side. The reflector 26 may be in contact with the circuit board 11. In FIGS. 1A and 1B, hatching of the diffusion plate 25 and the reflection plate 26 is omitted.

  The light emission of the LED 12 proceeds mainly toward the curved surface portion 15 of the main cover body 10a, but a part of the light is transmitted through the diffusion plate 25 and is reflected by the diffusion plate 25, and the light reflected from the diffusion plate 25 is reflected by the reflection plate. The light is reflected at 26 and irradiated again toward the diffusion plate 25. A part of the light transmitted through the diffusion plate 25 is transmitted through the main cover body 10a, and the other part is reflected by the inner surface of the main cover body 10a and irradiated toward the diffusion plate 25. Part of the reflected light is reflected from the diffusion plate 25 and the other part is transmitted through the diffusion plate 25. Further, the light undergoes a diffusion action due to refraction when passing through the diffusion plate 25 and the main cover body 10a.

  As described above, the light emitted from the LED 12 is scattered over a wide range due to the reflection and diffusion action by the diffusion plate 25 and the main cover body 10a and the reflection diffusion action by the reflection plate 26. As a result, the illumination lamp 1 is A surface emitting state is realized in a state where the presence of the LED 12 cannot be visually recognized at all. Further, the light emitted from the LED 12 can be efficiently used for illumination by reflection / diffusion by the reflection plate 26.

  The reflection plate 26 is formed of a thin metal plate (for example, a thin plate such as aluminum or stainless steel). Functionally, since at least the surface on the diffusion plate 25 side only needs to be formed on the reflecting surface, a metal film deposited on one surface such as a resin film may be used. As a reflecting means, a reflective film may be pasted on the surface of the substrate 11. It is also possible to use a resin molded product.

  As an example of a fitting portion of the circuit board 11, a first fitting groove 31 into which a long side edge of the circuit board 11 fits is formed on the inner surfaces of the two opposite side faces of the main cover body 10 a (that is, over the entire length). Formed so as to extend long in the X-axis direction). Furthermore, a pair of second fitting grooves 32 into which the long side edges of the diffusion plate 25 and the reflecting plate 26 are fitted are formed over the entire length at a position closer to the curved surface portion 15 than the first fitting portion 31 in the main cover body 10a. Has been. The second fitting groove 32 is set to have a groove width that fits tightly in a state where both side edges of the diffusion plate 25 and the reflection plate 26 overlap each other. It is also possible to separately provide a fitting groove into which the side edge of the diffusion plate 25 is fitted and a fitting groove into which the side edge of the reflection plate 26 is fitted.

  The first fitting groove 31 and the second fitting groove 32 are formed as a part of the main cover body 10a, and the light source unit 13, the diffusion plate 25, and the reflection plate 26 are arranged in the thickness direction and the width direction (Y-axis direction). It is kept incapable of slipping. As described above, since the main cover body 10a is an extruded product made of synthetic resin, the fitting grooves 31 and 32 can be easily processed.

  The auxiliary cover body 10b plays the role of a back cover of the main cover body 10a, and has a protrusion 10c that enters the main cover body 10a as shown in FIG. An outwardly protruding ridge 10d into which the long groove 19a of the main cover body 10a enters is formed in the convex portion 10c, and the main cover body 10a and the auxiliary cover body 10b are fitted by the fitting of the long groove 19a and the ridge 10d. Is held inseparable. The long groove 19a and the protrusion 10d can be fitted by sliding the main cover body 10a and the auxiliary cover body 10b in the longitudinal direction. Using the elastic deformation of the main cover body 10a, the main cover body 10a and the auxiliary cover body 10b are moved relative to each other in the thickness direction of the auxiliary cover body 10b to perform forced fitting using the elastic deformation of the cover body 10a. It is also possible to adopt.

  When assembling the illuminating lamp 1 having the above-described configuration, first, the main cover body 10a and the auxiliary cover body 10b are combined and fixed to form the cover member 10, and then both side edges along the longitudinal direction of the light source unit 13 are covered with the cover. At one end of the member 10, the light source unit 13 is inserted as it is in alignment with the first fitting groove 31.

  In this embodiment, since the reflection plate 26 is fitted to the LED 12, the reflection plate 26 is attached at the same time as the light source unit 13 is attached. That is, the reflecting plate 26 is set on the light source unit 13 so that the LED 12 is exposed from the through hole 27 of the reflecting plate 26, and in this state, the longitudinal both side edges of the light source unit 13 are the first fitting grooves of the main cover body 10a. 31 and the both longitudinal edges of the reflector 26 are inserted into the second fitting grooves 32 of the main cover body 10a. The diffusing plate 25 may be inserted into the second fitting groove 32 of the main cover body 10a after the light source unit 13 and the reflecting plate 26 are inserted, or the diffusion plate 25 may be put together with the reflecting plate 26 in a state of being superimposed on the reflecting plate 26. 2 may be inserted into the fitting groove 32.

  The light source unit 13, the reflection plate 26, and the diffusion plate 25 are attached (fitted) to the main cover body 10a only by relatively moving the main cover body 10a, the light source unit 13, the reflection plate 26, and the diffusion plate 25 in the longitudinal direction. Is very easy to do. And since the light source unit 13 is hold | maintained in the 1st fitting groove 31 over the full length, even if the length is long, it is hold | maintained in the stable state, without producing a bending. Further, since the light source unit 13 is only inserted into the first fitting groove 31, it can be easily inserted and removed when replacement is necessary. The same applies to the diffusion plate 25 and the reflection plate 26.

Since the cover bodies 10a and 10b are extrusion-molded products, they can be mass-produced by manufacturing intermediate products having a long length and cutting them into desired lengths. Manufacture of different lengths is also easy. Note that the length of the cover member 10 is the same as the size of a straight tube fluorescent lamp in which the illuminating lamp 1 is general (for example, tube diameter 32.5 mm × tube length 638 mm, tube diameter 32.5 mm × tube length 830 mm, tube diameter 25. 5 mm × tube length 1198 mm, etc.).

  On the other hand, the light source unit 13 has a male connector 20 disposed at one end in the longitudinal direction and a female connector 21 disposed at the other end. Therefore, a plurality (three in this case) of light source units 13 are arranged along the longitudinal direction as shown in FIG. 2 (b), and the adjacent male connector 20 and female connector as shown in FIG. 2 (a). When the power source 21 is connected, the power supplied from the one socket 3 side can be sequentially supplied to the adjacent light source units 13. That is, if the length in the longitudinal direction of the circuit board 11 shown in FIG. 1 is L, the light source unit 13 having a length approximately n times L (n is a positive number) can be easily formed, and the circuit unit 13 is shared. It is possible to reduce the cost of parts by using them as parts.

  Therefore, by connecting n light source units 13 and cutting the cover member 10 to a length corresponding to n times L, the illumination lamps 1 having different lengths can be easily manufactured. Even if the total length of the light source unit 13 is further increased, the circuit board 11 is fitted in the first fitting groove 31 over the entire length, so that the ease of assembly and replacement and the support stability are not impaired. Absent.

  Of course, in order to correspond to the cover member 10 that is long in the X-axis direction, it goes without saying that one light source unit longer than the dimension L may be prepared in advance as shown in FIG. Moreover, it is also possible to cut and use the light source unit manufactured long according to the length of the cover member 10. Note that the shapes of the male connector 20 and the female connector 21 shown in FIG. 2 (a) are merely examples, and the present invention is not limited to this, and may be appropriately selected for a type in which the terminal does not protrude to the outside or other types. It can be changed.

  The illumination lamp 1 can be used in various forms. For example, as shown in the first modified example of use in FIG. 3A, the lighting device 2 may have only the rotary socket portion 3 and a plurality of the lighting devices 2 may be arranged in series. In this case, it is necessary to provide a space for rotating the rotary socket portion 3 between the adjacent lighting devices 2. In FIG. 3A, the cost is reduced by sharing the socket portions at both ends.

  Furthermore, the illuminating lamp 1 is arranged not only in a series arrangement but also in a polygonal shape (here, a quadrangular case is illustrated) as shown in FIG. 3B as a second modified use example. It is also possible to do. In this case, the individually independent illumination lamps 1 may be arranged so as to form a polygon in a plan view, but by using the cap body 5 that can connect the two cover members 10 crossing each other. Alternatively, a plurality of cover members 10 (four in FIG. 3B) may be connected in a quadrangular shape and power may be supplied from one cap body 5.

  Since the illuminating lamp 1 using the LED 12 is excellent in illuminance, power saving, and durability, as shown in FIG. 3C as a third modified usage example, the illuminating device 2 is installed on the ceiling and is operated for 24 hours. It is suitable for use in stores and public facilities. Further, by providing a battery in the base 2a of the lighting device 2 and providing a switch circuit that switches the power supply due to a power failure, it can be used as an emergency light in the event of a power failure such as a disaster.

(2). Another form of cover member (Fig. 5)
Next, a modified example of the shape and internal structure of the cover member 10 will be described with reference to FIG. The second embodiment shown in FIG. 4A is an example in which a diffusion portion 25a having the same function as the diffusion plate 25 is formed in advance on the inner peripheral surface of the curved surface portion 15 in the main cover body 10a. That is, the main cover body 10a
Is formed by forming a large number of fine irregularities (stretches of irregularities extending in the longitudinal direction) on the inner peripheral surface of the curved surface portion 15, thereby facilitating component management. At the same time, the assembly work can be saved.

  In the third modification shown in FIG. 4 (b), the cover member 10 is formed in a cylindrical shape having an oval cross section in which two curved surface portions 15 are provided on both sides of the axis, and the two curved surface portions are formed. Corresponding to 15, two light source units 13 having LEDs 12 mounted on one side are arranged back to back.

  In 4th Embodiment shown in FIG.4 (c), the fitting groove | channel 31a is formed in the overlapping part of the main cover body 10a and the auxiliary cover body 10b. That is, the fitting groove 31a is formed by the stepped portion provided in the auxiliary cover body 10b and the flat surface of the main cover body 10a. Needless to say, the main cover body 10a and the auxiliary cover body 10b are integrally held by appropriate means such as screws.

  In the fifth embodiment shown in FIG. 4D, the cover member 10 is provided with a flange-like attachment portion 35, and the attachment portion 35 is fixed to the wall surface portion 40, the ceiling portion, or the like. The illuminating lamp 1 can also be directly fixed to the base 2a of the illuminating device 2 shown in the first embodiment.

  6th Embodiment shown in FIG.4 (e) is an example which attached the illuminating lamp 1 to the ceiling part 41 as indirect illumination. That is, in this example, the main cover body 10a is arranged such that the curved surface portion 15 is convex toward the ceiling portion 41, and the light of the LED 12 is configured to emit light toward the ceiling portion 41. The flange-shaped attachment portion 35 provided on the auxiliary cover body 10b is fixed to the ceiling portion 41, and the reflection plate 26 is disposed on the ceiling portion 41 side. Since the LED 12 emits light strongly, sufficient illuminance can be obtained even when used as indirect illumination.

  In FIG. 4 (f), the seventh embodiment is similar to the third embodiment, in which the cover member 10 is formed in a cylindrical shape, and the light source unit 13 in which the LEDs 12 are mounted on both the front and back surfaces is disposed therein. ing. In this embodiment, the illuminating lamp 1 emits light over substantially the entire circumference. Therefore, it is suitable when it is necessary to illuminate the entire surroundings like a street lamp. Needless to say, the reflecting plate 26 and the diffusing plate 25 can be used together.

  In the eighth embodiment shown in FIG. 4G, the cover member 10 is formed in a cylindrical shape, and the light source unit 13 having the LED 12 mounted on one side is inserted therein. In order to obtain a wide range, the light source unit 13 is shifted from the axial center so as to approach the outer periphery of the cover member 10 on the side opposite to the side on which the LEDs 12 are disposed.

  In addition to the embodiment illustrated in FIG. 4, for example, when the cover member 10 (the main cover body 10 a and the auxiliary cover body 10 b) is extruded with a synthetic resin, a resin (translucent resin) having different translucency is obtained by a coextrusion method. (A light resin, a light shielding resin, a translucent resin, etc.) or a resin having a different color may be combined to form a partial difference in translucency and color.

(3). Ninth embodiment (FIG. 5)
As shown as the ninth embodiment, the cover member 10 can be formed in an annular shape (ring shape) (it can also be formed in a non-circular annular shape such as a polygon). This is the embodiment of claim 3.

The cover member 10 includes a main cover body 10a (corresponding to the first cover body of claim 3) 15 that covers the light source unit 13 from the side on which the LED 12 is mounted, and an auxiliary cover body 10b that covers the light source unit 13 from the side opposite to the LED 12 (claim). 3 corresponding to the second cover body 3). That is, the cover member 10 includes a half-shaped main cover body 10a and an auxiliary cover body 10b, and the light source unit 13 is disposed therein.

  As shown in FIG. 5B, the main cover body 15 and the auxiliary cover body 16 have a substantially U-shaped (or semicircular) cross-sectional shape, and are hollow as a whole by overlapping the open ends with each other. Is made.

  A fitting groove 31a is formed in an overlapping portion between the main cover body 10a and the auxiliary cover body 10b. The main cover body 10a and the auxiliary cover body 10b are manufactured by an injection molding method, and are positioned by fitting each other.

  The circuit board 11 of the light source unit 13 may be formed in a ring shape in plan view with a single circuit board. However, since the component cost increases, a plurality of arc-shaped circuit boards having divided rings are connected in plan view. It has a ring shape. Here, the four light source units 13 are used, and the substrates are physically connected to each other by the connecting portion 22 and are also electrically connected. Further, the connected light source unit 13 is electrically connected to a connection portion 6 provided at one place on the circumference of the cover member 10, and the power connector 7 is inserted into the connection portion 6 so that the LED 12 is connected. Power is being supplied.

  On the surface of the auxiliary cover body 10b that faces the main cover body 10a, a stepped portion that becomes a fitting groove 31a is formed, and each side edge of each substrate 11 is fitted into the fitting groove 31a. The main cover body 10a and the auxiliary cover body 10b are provided with a plurality of fixing portions 10e and 10f protruding on the inner peripheral side at intervals in the circumferential direction as spaces for fixing them with the screws 19. (In FIG. 10A, only one location is shown.) Therefore, the light source unit 13 is sandwiched between the auxiliary cover body 10b and the main cover body 10a by fixing the auxiliary cover body 10b and the main cover body 10a with the screws 19.

  Here, as shown in FIG. 5B, a diffuser plate 25 having a curved cross-sectional shape is disposed between the main cover body 10a and the light source unit 13, and both side edges of the diffuser plate 25 are also disposed on the light source unit 13. And is fitted in the fitting groove 31a. The diffusion plate 25 may be previously brought into close contact with the curved surface portion 15 of the main cover body 10a, or may be integrally formed on the inner peripheral surface of the main cover body 10a by a two-color molding method or the like. Good.

  Also in this embodiment, the light source unit 13 is stably held because it is sandwiched between the main cover body 10a and the auxiliary cover body 10b over its entire length. The light source unit 13 can be easily set when the main cover body 10a and the auxiliary cover body 10b are assembled. The configuration of the annular cover member 10 can also be applied to the embodiments of FIGS. 4 (a), (c), (d), and (e). Moreover, you may apply to comprising the example of FIG.4 (b), (f), (g) by two cover bodies like 9th Embodiment.

(4). Tenth embodiment (FIG. 6)
Next, a description will be given using the tenth embodiment displayed in FIG. In addition, the same element as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits detailed description.

  In the tenth embodiment, the main body (apparatus) of the fluorescent lamp illumination device 102 is used to replace the illumination lamp 101 with a fluorescent lamp. That is, the illumination lamp 101 can be used by replacing the connection sections provided for the fluorescent lamps in the socket sections 103 and 104 of the illumination apparatus 102 with the connection sections 103a and 104a for the illumination lamp 101. . Instead of replacing only the connecting portion, the entire socket portion may be replaced for the illumination lamp 101.

  A circuit unit 14 including an AC / DC converter and a voltage control unit is provided in the base 102a. Since the ballast provided for the fluorescent lamp is not necessary for the illumination lamp 101, the connecting portions 103a and 104a are not connected to the ballast. Then, power can be supplied to the LED 12 via the circuit portion 14 and one connection portion 103a, and the other connection portion 103b is not used for electrical connection. The circuit unit 14 may be downsized and built in the connection unit 103 a or mounted on the light source unit 13.

  The first cap body 117 attached to one end of the cover member 10 has a terminal 117a that protrudes outward. By fitting the first cap body 117 into the cover member 10, the terminal 117a, the male connector 20, Are electrically connected. Here, the first cap body 117 is composed of two members. When the illuminating lamp 101 is fitted into the socket portion 103, the male connector 20 and the connection portion 103a are electrically connected via the terminal 117a of the first cap body 117, and the LED 12 can be caused to emit light.

  The second cap body 118 attached to the other end of the cover member 10 has a terminal 118a that protrudes outward and is inserted into the connection portion 104a. However, the LED 12 can only supply power from the male connector 20 side. Therefore, the terminal 118a is a dummy terminal that is not electrically connected. That is, the terminal 118 a is not electrically used, but is used for fitting and holding the illumination lamp 101 with respect to the illumination device 102.

  The connection portion 103a is formed to be elastically displaceable (movable) in the X-axis direction with respect to the socket portion 103, while the connection portion 104a is formed to be non-displaceable (fixed) with respect to the socket portion 104. Therefore, when attaching the illuminating lamp 101, after inserting the terminal 117a into the connecting portion 103a and displacing it to the inner side, the terminal 118a is inserted into the connecting portion 104a while returning the connecting portion 103a to the original position. I will take it.

  Instead of this mounting method, a groove-shaped portion is provided in the connecting portions 103a, 104a so that the terminals 117a, 118a can be slid in a direction perpendicular to the axis thereof, and the terminals 117a, 118a are provided in the groove-shaped portions. Alternatively, the connecting portions 103a and 104a may be rotated about 90 degrees together with the illuminating lamp 101. In the case of this rotation method, the arrangement of the terminals 117a and 118a must be set in advance so that the LED 12 faces the side opposite to the base 102a after the rotation.

  In addition, you may apply the linear or cyclic | annular structure illustrated as 2nd-9th embodiment to the fluorescent lamp alternative type illumination lamp 1 like 2nd Embodiment.

  In the tenth embodiment, since the socket portions 103 and 104 are fixed and have a constant distance from each other, as shown in FIG. 6B, a plurality of illumination lamps 101 are arranged in series in close contact with each other. can do.

(5). Eleventh embodiment (FIG. 7)
Next, the illumination lamp 201 of the eleventh embodiment displayed in FIG. 7 will be described. This embodiment embodies Claim 5 and the same reference numerals are given to the same elements as those in the first embodiment, and the detailed description is omitted. The eleventh embodiment includes a light guide 50 that is elongated in the X-axis direction. End members 220 are disposed on one end surface and the other end surface of the light guide 50 in the longitudinal direction. Further, an LED 12 that irradiates light toward the light guide 50 is provided.

The light guide 50 is formed in a U-shaped cross section in which the outer peripheral surface 50a and the inner peripheral surface 50b are both curved in the same direction. The outer peripheral surface 50a of the light guide 50 is covered with a diffusion plate 225 on which a number of fine irregularities are formed, and the inner peripheral surface 50b of the light guide 50 is provided with an inner peripheral cover member with a reflector 226 interposed therebetween. 210 is covered. Therefore, the diffusion plate 225, the reflection plate 226, and the inner cover member 210 are all formed in a substantially U-shaped cross section that is long in the X-axis direction so as to follow the shape of the light guide 50.

  The light guide 50 is formed of an acrylic material as an example of a translucent resin. Then, as shown in the schematic enlarged view of FIG. 7 (e), on the inner peripheral surface 50 b of the light guide 50, a number of mountain-shaped undulations extending in the direction in which the ridge line intersects the axis of the light guide 50. Is forming. Accordingly, the light traveling in the X-axis direction inside the light guide 50 is refracted and changed its direction by the prism phenomenon by hitting a large number of mountain-shaped undulations, and is emitted from the outer peripheral surface 50b. The refracting means is not limited to the above-described mountain-shaped undulations, and other forms may be applied.

  Since the outer peripheral surface 50a of the light guide 50 is covered with the diffusion portion 225, the light emitted from the outer peripheral surface 50a of the light guide 50 is diffused through the diffusion portion 225, and the outer peripheral surface 50a of the diffusion portion 225 is Surface emission occurs in the X-axis direction. Moreover, since the reflecting plate 226 is provided on the inner peripheral surface 50b of the light guide 50, the light emitted from the inner peripheral surface 50b of the light guide 50 is reflected and redirected to the outer peripheral surface 50a side. Lighting efficiency can be increased. The same effect can be obtained even if the reflection plate 226 is replaced with the diffusion plate 225.

  The circuit board 11 of the light source unit 213 is formed in a plan view shape so as to cover both ends of the light guide 50 (see FIG. 7D), and the LED 12 emits light toward the light guide 50. The light source unit 213 is attached to the light guide 50. As shown in FIGS. 7B and 7D, here, the three LEDs 12 are arranged in an arc shape on one circuit board 11, but the LEDs 12 of one light source unit 213 and the other light source unit 213 are arranged. The LEDs 12 are arranged in a state of being displaced by substantially equal intervals in the circumferential direction when viewed from the X-axis direction. For convenience of explanation, in FIG. 7C, the LEDs on the near side of the light guide 50 are indicated by broken lines, and the LEDs on the far side are indicated by solid lines.

  In this way, if the arrangement of the LEDs 12 of the two light source units 213 is arranged with the positions shifted in the circumferential direction in projection view, the advantage that the light of the LEDs 12 incident from both ends of the light guide 50 can be prevented from being buffered inside, There is an advantage that the arrangement interval of the LEDs 12 on one circuit board 11 can be widened and the LED 12 can be easily attached to the circuit board 11. As shown in FIGS. 7A and 7B, the light source unit 213 is provided with a terminal 213a that is electrically connected to the LED 12 on the surface opposite to the surface on which the LED 12 is mounted.

  First, positioning members 217 for positioning the light source unit 213 with respect to the light guide 50 are arranged on both end faces in the longitudinal direction of the light guide 50, and the light source unit 213 is arranged outside the X-axis direction. . A spacer member 219 and a cap member 218 are sequentially arranged on the outer side of the light source unit 213, and these are fixed to the light guide 50 by being fastened together with screws 19. In this embodiment, the light source unit 213, the positioning member 217, the spacer member 219, and the cap member 218 correspond to the end member 220 described in claim 5, but the configuration of the end member 220 is not limited to this.

  The spacer member 219 and the cap body 218 are provided with holes for projecting the terminals 213a toward the sockets 203 and 204. The terminal 213a protruding outward from the cap body 218 is electrically connected to the socket portions 203 and 204. In this embodiment, since the two light source units 213 attached to both ends of the light guide 50 are not electrically connected, power is supplied from the corresponding socket portions 203 and 204 via the terminals 213a. However, the two light source units 213 may be connected inside the illuminating lamp 201 so that power is supplied from one socket 203 side.

  In addition, since the connection part 203a of one socket part 203 is comprised so that elastic displacement is possible along the X-axis direction, the attachment or detachment of the illuminating lamp 201 with respect to the illuminating device 2 utilizes the elastic displacement of the connection part 203a. Done.

  In the third embodiment, the light guide 50 is formed long in the X-axis direction, but the light source unit 213 only needs to be disposed on both end faces of the light guide 50 in the longitudinal direction. That is, although it is the linear elongated illuminating lamp 201 using the LED 12 as a light source, it is not necessary to form the light source unit 213 to be long, and therefore the end member 220 including the light source unit 213 is firmly attached to the end surface of the light guide 50. And it can be easily attached. Therefore, there is no need to worry about damage due to bending of the light source unit 213.

  In addition, in 11th Embodiment, although the light source unit 213 is attached to the both end surfaces of the X-axis direction of the light guide 50, you may attach only to either one. Further, the shape of the light guide 50 is not limited to the shape shown in FIG. 7, and the inner peripheral surface 50 b on which the irregularities are formed is formed from the incident position, as indicated by a one-dot chain line in FIG. If the LED 12 is inclined so as to be closer to the outer peripheral surface 50a as the distance is increased, the irradiation rate of the LED 12 with respect to the inner peripheral surface 50b is increased, so that the refractive efficiency can be improved. Further, the LED 12 may not be fixed to the end member 220 but may be sandwiched between the end member 220 and the light guide 50, or may be fixed to the end surface of the light guide 50 with screws or the like. Also good.

(6). Twelfth embodiment (FIGS. 8 to 11)
Next, a twelfth embodiment displayed in FIGS. 8 to 11 will be described. This embodiment is basically similar to the first embodiment, and the cover member 10 is composed of a main cover body 10a and an auxiliary cover body 10b, and the light source unit 13 is disposed therein. Similar to the first embodiment, the reflector 26 is provided but the diffuser 25 is not provided. In the present embodiment, the reflecting plate 26 and the auxiliary cover body 10b also serve as the holding member recited in the claims, and therefore the main cover body 10a corresponds to the cover member recited in the claims. The auxiliary cover body 10b uses an extruded product made of a light metal such as aluminum.

  As shown in FIGS. 9 and 11, the main cover body 10a is formed in a U-shaped cross section having a curved portion 15 as in the first embodiment, and an example of a fitting portion is provided on two opposed inner surfaces. The dovetail-like fitting groove 51 is formed. On the other hand, the auxiliary cover body 10b has an inward convex portion 10c as in the first embodiment, and a long groove 19a into which the screw 19 is screwed is formed in the convex portion 10c so as to open inward. Lateral ridges 52 that fit into the fitting grooves 51 of the main cover body 10a are formed.

  As clearly shown in FIG. 11 (C), the protrusion 10c of the auxiliary cover body 10b has a hook-shaped engagement claw that protrudes further from the long groove 19a and the lateral protrusion 52 toward the inside of the main cover body 10a. 53 is formed. The engaging claw 53 has a claw protruding outward in the left and right directions in FIGS. In addition, two dovetail mounting grooves 54 on the left and right sides are formed on the base portion of the auxiliary cover body 10b opposite to the main cover body 10a so as to be close to the two side surfaces of the main cover body 10a. The mounting groove 54 has a substantially trapezoidal shape, and an inward flange 55 is formed at the base of the auxiliary cover body 10b to form the mounting groove 54.

  Further, outward flanges 56 are formed on the left and right outer sides of the inward flange 55, and the side end surfaces of the main cover body 10 a that extend long are in close contact with or close to the outward flange 56. Accordingly, the outward flange 56 of the auxiliary cover body 10b constitutes a side surface portion of the main cover body 10a and can be visually recognized from the outside. A portion of the auxiliary cover body 10 b between the lateral convex 52 and the outward flange 56 is an engagement groove 57, and the inward engagement protrusion 58 of the main cover body 10 a is fitted into the engagement groove 57. waiting. Accordingly, in the present embodiment, the engaging groove 58 and the engaging ridge 58 also constitute the fitting means. According to the claims, the main cover body 10a includes the engaging ridge 58 and the fitting portion. (It is also possible to eliminate the fitting groove 51 and use only the engaging protrusion 58).

  The attachment groove 54 can be fitted into the support fitting 59 clearly shown in FIG. That is, the support bracket 59 is fixed to the enforcement portion 60 such as a ceiling or a wall with screws 61, and has two side plates 62 spread in a reverse letter C shape. A claw piece 63 entering the groove 54 is bent. When the claw piece 63 is caught by the inward flange 55, the auxiliary cover body 10 b is held by the enforcement portion 60 so as not to drop off. The support fitting 59 is formed by bending a pressing piece 64 that elastically contacts the bottom surface of the auxiliary cover body 10b. Due to the presence of the pressing piece 64, the auxiliary cover body 10b is held in a state without backlash.

  As a means for holding the auxiliary cover body 10b on the support bracket 59 so as not to fall off (instead of providing the claw piece 63 on the side plate 62) or in addition to this, FIG. 11 (e) shows a solid line and FIG. As indicated by the alternate long and short dash line in (d), it is possible to bulge and form an outward dowel 65 on the side plate 62 and hook the dowel 65 on the inward flange 55 of the auxiliary cover body 10b.

  As clearly shown in FIG. 11 (e), the reflection plate 26 is concavely concaved toward the curved portion 15 of the main cover body 10a when viewed from the axial direction, and the two longitudinal side edges face the side of the auxiliary cover body 10b. A foot piece 65 mounted on the convex 52 is integrally formed, and a plurality of locking claws 65a that engage with the engaging claws 53 of the auxiliary cover body 10b from the outside are formed on the foot piece 65 in a jumping state. Has been. In the reflecting plate 26, a locking claw 65a is provided with a pull-out hole 66 for facilitating die cutting when the locking claw 65a is formed by an injection molding method.

  As a means for attaching the reflecting plate 26 to the auxiliary cover body 10b, the reflector 65 may be moved in the thickness direction and pressed against the auxiliary cover body 10b to elastically deform the foot piece 65 at the position of the locking claw 65a. Or you may slide the reflecting plate 26 to the longitudinal direction, and may engage the latching claw 65a with the horizontal protrusion 52. As shown in FIG. It is also possible to form the foot piece 65 in a flying state.

  The reflecting plate 26 is formed with a pair of a suspension piece 67 and a restriction piece 68 for holding the circuit board 11 at its longitudinal side edge. A support claw 67 a that holds the circuit board 11 so as not to drop off is formed on the hanging support piece 67 in a flying state. In the reflecting plate 26, a hole 69 for forming the support claw 67a is formed at a location where the support claw 67a is provided. Therefore, the restricting piece 68 is divided at the support claw 67a. The hanging support piece 67 and the regulating piece 68 can be set to a short length and can be formed in a jumping state, for example, formed at three locations near the both ends of the reflector 26 and in the middle. Is also possible.

  Similar to the first embodiment, the reflecting plate 26 has a through hole 27 for exposing the LED. The reflecting plate 26 is attached to the reflecting plate 26 by moving in the thickness direction and pressing the reflecting plate 26 toward the back surface of the reflecting plate 26 to elastically deform the suspension piece 67 of the reflecting plate 26.

  The illuminating lamp 1 has an end cap 71. The end cap 71 has a stepped protrusion 71a that fits into the main cover body 10a from the inside, and a counterbore hole 72 into which the head of the screw 19 fits is formed on the outer surface. Furthermore, an escape hole 73 communicating with the mounting hole 54 of the auxiliary cover body 10b is also provided.

As shown in FIG. 9, a pair of terminal holes 11a are formed at both ends of the circuit board 11, and terminal pins 75 of the first intermediate connector 74 shown in FIGS. 9 and 10 (a) are formed in the terminal holes 11a. Can be inserted, the terminal pin 75 of the end connector with cable 76 shown in FIG. 10B can be inserted, or the terminal pin 75 of the second intermediate connector 77 shown in FIG. 10C can be inserted.

  The first intermediate connector 74 is used when connecting the illuminating lamp 1, which has the end cap 71 attached thereto and forms one completed unit. Therefore, any number of the illuminating lamps 1 as finished products can be connected. The end cap 71 is formed with a recess 78 for avoiding interference with the first intermediate connector 74. In addition, notches 79 for avoiding interference with the connectors 74, 76, 77 are formed at both ends of the auxiliary cover body 10b.

  When only one illuminating lamp 1 is used, the end connector 76 is connected to the terminal hole 11 a on only one side of the both ends of the circuit board 11. When a plurality of illuminating lamps 1 are connected and used, adjacent circuit boards 11 are connected by a first intermediate connector 74, and an end connector 76 is connected to one end or the other end of the continuous body. In addition, it is possible to arrange a plurality of circuit boards 11 in series on the main cover body 10a and the auxiliary cover body 10b one by one. In this case, the adjacent circuit boards 11 as shown in FIG. The second intermediate connector 77 is used for connection.

  In assembling the illuminating lamp 1 according to the twelfth embodiment, the circuit board 11 is first set on the reflecting plate 26, the reflecting plate 26 is set on the auxiliary cover body 10b, and the auxiliary cover body 10b is then set on the main cover. It is performed by a procedure of inserting into the body 10a or setting by forced fitting. Since the assembly is performed while sequentially unitizing in this way, the assembly can be easily performed.

  Further, since the circuit board 11 is attached to the main cover body 10a via the reflecting plate 26 and the auxiliary cover body 10b, the width dimension of the circuit board 11 can be made smaller than the lateral width of the main cover body 10a, and the light source unit. There are advantages that the manufacturing cost of 13 can be suppressed and that one type of light source unit 13 can be used for the illumination lamps 1 having different sizes. In the present embodiment, no diffusing portion is provided, but surface emission can be performed so that the presence of the LED 12 is not known at all.

  A number of grooves 80 are formed on the two outer surface portions of the illuminating lamp 1 from the opening edge. This has a decorative effect and an effect of making it difficult to visually recognize the auxiliary cover body 10b and the reflector 26. (It is difficult to visually recognize the auxiliary cover body 10b and the reflecting plate 26 because light is refracted at the groove 80). Of course, it is also possible to make it the smooth surface where the groove 80 does not exist.

  The size of the illumination lamp 1 can be set arbitrarily. For example, the total length can be 300 mm, and the width dimension of the main cover body 10a (the length in the left-right direction in the case of FIG. 11B) can be about 32 mm. When connected as shown in FIG. 10C, the length can be set to (integer multiple of the length of the circuit board 11 + exposed width dimension of the end cap 71). When the connectors 74, 76, 77 are fitted into the terminal holes 11a of the circuit board 11, there is an advantage that the structure is simplified.

(7). Variation of 12th Embodiment The cross-sectional shape of the main cover body 10a can be arbitrarily set. For example, as shown by a two-dot chain line in FIG. It is also possible to adopt a trapezoidal cross section or a mountain shape.

  FIG. 12 shows another example of the installation structure of the illumination lamp 1. In this example, the auxiliary cover body 10b can be directly fixed to the enforcement place with a screw 61, and the end of the auxiliary cover body 10b is located outside the end face of the illuminating lamp 1, the light source unit 13, and the reflector 26. It is exposed and has a mounting hole 81 in the exposed portion. In this example, an end stopper 82 and an auxiliary cap 83 that covers the exposed portion of the auxiliary cover body 10b are used for positioning the main cover body 10a, the light source unit 13, and the reflector 26.

  The end stopper 82 has a substantially L-shaped cross section having a bottom piece and an upright piece so as to cover the end surface of the main cover body 10a while overlapping the exposed portion of the auxiliary cover body 10b. An inwardly protruding portion 82a that fits from the inside to the inside, and an outwardly protruding portion 82b that fits from the inside to the auxiliary cap 83 are formed. A mounting hole 81 into which the screw 61 is fitted is also formed in the bottom piece of the end stopper 82. Therefore, the end stopper 82 and the auxiliary cover body 10b are fastened together with the screw 61 at the enforcement place.

  The auxiliary cap 83 has an outer peripheral plate and an end plate, and an engagement protrusion 84 that fits into the engagement groove 57 of the auxiliary cover body 10b is provided on the inner peripheral surface. The state covered with the auxiliary cap 83 is shown in FIG.

(8). Other Embodiments of the present invention have been described, but the present invention can be embodied in various ways other than the above-described embodiments. For example, it is possible to mount a light emitting element such as an LED on the reflection plate, and integrate the reflection plate and the circuit board. Alternatively, the circuit board may be fixed or bonded to the auxiliary cover body (base body) in the embodiment, and the auxiliary cover body may be fitted into the main cover body.

  It is also possible to attach the circuit board to another holding member that is neither a reflection plate nor an auxiliary cover body, and to fit the holding member into the cover member and attach the holding member to the reflection plate or the auxiliary cover body.

  The present invention can be applied to an illuminating lamp to exhibit its usefulness, and thus can be used industrially.
