  FIG. 3 is a cross-sectional view of the lamp 100 according to the first embodiment. Specifically, FIG. 3 is a sectional view of the lamp 100 taken along line A-A ′ of FIG. 1.

  As shown in FIGS. 1, 2, and 3, the housing 110 is a housing (envelope) for housing the LED module 300. The shape of the housing 110 is long.

  The housing 110 includes a cover 200 and a base 400. Each of the cover 200 and the base 400 extends along the longitudinal direction of the casing 110. Hereinafter, the longitudinal direction of the housing 110 is also referred to as the housing longitudinal direction.

  The cover 200 is made of translucent plastic. Note that the cover 200 is not limited to plastic, and may be made of acrylic, polycarbonate, glass, or the like.

  The shape of the cover 200 is a long shape. Moreover, the cover 200 is comprised so that the LED module 300 as a light emitting module may be covered.

  As shown in FIG. 3, the cross-sectional shape of the cover 200 is a substantially arc shape. The thickness of the cover 200 is 0.7 [mm], for example. However, the cross-sectional shape of the cover 200 is not particularly limited, and may be, for example, a shape combining a straight line and a curved line such as a quadrangular shape.

  Moreover, it is preferable that the outer surface or inner surface of the cover 200 is subjected to a diffusion treatment. Thereby, the light emitted from the LED module 300 can be diffused.

  As shown in FIG. 4, the LED module 300 includes a substrate 310 and a light emitting unit 320.

  The substrate 310 is a long rectangular substrate extending in the longitudinal direction of the housing. The substrate 310 is a ceramic substrate, for example. The ceramic substrate is made of alumina or translucent aluminum nitride.

  Note that the substrate 310 is not limited to a ceramic substrate, and may be a resin substrate, a glass substrate, a flexible flexible substrate, an aluminum substrate, or the like.

  Here, the length in the longitudinal direction of the substrate 310 is L1, and the length in the short direction is L2. In this case, L1 and L2 are defined by a relational expression of 10 ≦ L1 / L2, for example. That is, L1 is 10 times or more of L2.

  A light emitting unit 320 that emits light is provided on the main surface of the substrate 310. Hereinafter, in this specification, the main surface of the substrate 310 is a surface on which the light emitting unit 320 is provided.

  Specifically, on the main surface of the substrate 310, the light emitting unit 320 is formed up to both end edges in the longitudinal direction of the substrate 310. That is, the light emitting unit 320 is formed without interruption from the end surface of one short side of the substrate 310 to the end surface of the other short side.

  The light emitting unit 320 includes a plurality of LEDs 321 and a sealing member 322.

  The plurality of LEDs 321 are linearly mounted on the main surface of the substrate 310 along the longitudinal direction of the substrate 310. In the present embodiment, as an example, 24 LEDs 321 are mounted on each substrate 310.

  The LED 321 is a bare chip that emits monochromatic visible light. Each LED 321 is bonded to the substrate 310 by a die attach material (die bond material). The LED 321 is, for example, a blue LED chip that emits blue light. The blue LED chip is a gallium nitride based semiconductor light emitting element having a center wavelength of 440 nm to 470 nm, which is made of an InGaN based material.

  The plurality of LEDs 321 included in the light emitting unit 320 are electrically connected in series by a wiring 330 described later formed on the surface of the substrate 310. Hereinafter, the plurality of LEDs 321 included in the light emitting unit 320 are collectively referred to as a light emitting unit LED group.

  Note that all of the plurality of LEDs 321 constituting the LED group in the light emitting unit may not be connected in series. For example, the 24 LEDs 321 constituting the LED group in the light emitting unit may be constituted by three sets of LED groups electrically connected in parallel. In this case, the eight LEDs 321 constituting each of the three sets of LED groups are electrically connected in series.

  The sealing member 322 collectively seals all the LEDs 321 mounted on one substrate 310. On the main surface of the substrate 310, the sealing member 322 is formed up to both end edges in the longitudinal direction of the substrate 310. That is, the sealing member 322 is formed without interruption from the end surface of one short side of the substrate 310 to the end surface of the other short side.

  The linear sealing member 322 (light emitting unit 320) is formed on a straight line passing through the center of the substrate 310 in the short direction. The sealing member 322 (light emitting unit 320) may be formed closer to one long side than a straight line passing through the center of the substrate 310 in the short direction.

  The shape of the sealing member 322 is a substantially semicircular dome shape whose section is convex upward. The sealing member 322 is a phosphor-containing resin containing a phosphor that is a wavelength converter. The sealing member 322 is a wavelength conversion layer that converts the wavelength of light from the LED 321.

  The wavelength conversion layer includes an optical wavelength converter for converting the wavelength of light. In the present embodiment, the sealing member 322 that is a wavelength conversion layer includes a phosphor as an optical wavelength converter.

  Therefore, the sealing member 322 is a phosphor layer containing phosphor fine particles that excite the light of the LED 321. Incidentally, yellow phosphor fine particles are used as the phosphor fine particles, and the phosphor-containing resin is constituted by dispersing this in a silicone resin.

  The yellow phosphor fine particle is, for example, a YAG (yttrium, aluminum, garnet) phosphor material. The yellow phosphor fine particles are not limited to the YAG phosphor material, and may be, for example, a silicate phosphor material.

  As described above, the light emitting unit 320 includes the plurality of LEDs 321 as blue LED chips and the sealing member 322 containing yellow phosphor fine particles. Therefore, the yellow phosphor fine particles are excited by the blue light of the blue LED chip to emit yellow light. As a result, white light is emitted from the light emitting unit 320 by the excited yellow light and the blue light of the blue LED chip.

  The LED module 300 further includes a wiring 330, an electrostatic protection element 340, two electrode terminals 350, and a wire 331.

  The wiring 330 is a metal wiring made of tungsten (W) or copper (Cu). The wiring 330 is patterned on the main surface of the substrate 310.

  Each of the two electrode terminals 350 is electrically connected to the wiring 330.

  The electrostatic protection element 340 is, for example, a Zener diode. The electrostatic protection element 340 prevents the LED 321 from being destroyed by the reverse polarity static electricity generated on the substrate 310. The electrostatic protection element 340 is electrically connected to the plurality of LEDs 321 through the wiring 330.

  The electrode terminal 350 is formed on the main surface of the substrate 310. The electrode terminal 350 is a power supply / reception unit (external connection terminal) for receiving DC power from an external power source and supplying DC power to the LED 321. The electrode terminal 350 is electrically connected to the wiring 330.

  For example, when a direct current is supplied from the electrode terminal 350 to the LED 321, the LED 321 emits light, and desired light is emitted from the LED 321.

  In the present embodiment, the two electrode terminals 350 are offset to one long side of the substrate 310 with the sealing member 322 as a reference.

  The wire 331 is an electric wire for electrically connecting the adjacent LED 321 and the wiring 330. The wire 331 is, for example, a gold wire. A p-side electrode and an n-side electrode for supplying current are formed on the upper surface of the LED 321. Each of the p-side electrode and the n-side electrode and the wiring 330 are wire-bonded by a wire 331.

  As described above, a plurality of LED modules 300 are mounted on the mounting plate 410 in a straight line along the longitudinal direction of the housing as shown in FIG.

  That is, the plurality of LED modules 300 are disposed in the housing 110. That is, the substrate 310 of the LED module 300 is a base on which the semiconductor light emitting element (LED 321) is mounted, which is disposed in the housing 110.

  Specifically, the plurality of LED modules 300 are mounted on the mounting plate 410 of the base 400. That is, the substrate 310 as a base is placed on the placement plate 410 of the base 400. That is, the substrate 310 as a base is placed (connected) on the base 400.

  In addition, as shown in FIG. 2, of the two adjacent LED modules 300, the electrode terminal 350 of one LED module 300 and the electrode terminal 350 of the other LED module 300 are electrically connected by the wiring 10. Is done.

  Thereby, the plurality of LEDs 321 in the plurality of LED modules 300 on the mounting plate 410 are connected in series. The wiring 10 is made of a conductive member such as a lead wire made of a conductive wire with an insulating coating, for example.

  Next, the base will be described.

  Two bases 201 are fixedly provided at both ends of the casing 110 in the longitudinal direction.

  A pair of base pins 202 are fixed to the base 201. The base pin 202 is made of a conductive metal.

  In addition, a lighting circuit (not shown) for receiving power and causing the LEDs of the LED module 300 to emit light is installed inside or outside the lamp 100 using one or both of the two caps 201. The lighting circuit can be configured by a rectifier circuit including a diode bridge using four Zener diodes, for example.

  In the lamp 100 according to the present embodiment, power is supplied to the LED module 300 using one of the two caps 201 as an example. In this case, a lighting circuit (not shown) is provided in the one base 201. Also, in this case, the other base 201 of the two bases 201 is used for mounting on a lighting fixture.

  Further, in this case, the one base 201 receives power (AC power) used for light emission of the semiconductor light emitting element (LED 321) from the external commercial AC power source via the base pin 202. That is, AC power is supplied to the one base 201 from the outside. That is, the base pin 202 of the one base 201 is a pin for receiving the AC power from an external commercial AC power source.

  However, in the present embodiment, the base pin provided with the power supply terminal is described, but the base 201 according to the present invention may not function as a power supply unit and may function as a non-power supply member to which power is not supplied. . That is, the base 201 may simply function as an attachment portion for being attached to the instrument. In this manner, when the base 201 functions as a non-power supply member, power supply to the LED module 300 may be performed using a power supply terminal such as a connector. A connector or the like easily functions as a power supply terminal by connecting one end to the LED module 300 and the other end to an external power supply.

  The lighting circuit is electrically connected to the plurality of LED modules 300 so that power can be supplied to the plurality of LED modules 300.

  In this case, the lighting circuit is electrically connected to the electrode terminal 350 of the LED module 300 placed at the location closest to the base 201 that accommodates the lighting circuit by wiring. In addition, the lighting circuit is a wiring electrically connected to the electrode terminal 350 of the LED module 300 placed at a position farthest from the base 201 that accommodates the lighting circuit, and the casing 400 Wirings routed along the direction are connected.

  As shown in FIG. 6, the end plate 411a and the end plate 211a are formed such that the overlapping portion of the end plate 411a is disposed closer to the end plate 221 of the base 201 than the overlapping portion of the end plate 211a.

  Note that the shapes of the end plate 411a and the end plate 211a are not limited to the shapes shown in FIG. For example, as shown in FIG. 7, the end plate 411a and the end plate 211a are formed so that the overlapping portion of the end plate 211a is disposed closer to the end plate 221 of the base 201 than the overlapping portion of the end plate 411a. May be.

  Note that the end plate 411b and the end plate 211b have the same configuration as the end plate 411a and the end plate 211a, respectively. Therefore, detailed description of end plate 411b and end plate 211b will not be repeated.

  As shown in FIG. 6, in the vicinity of each of the first housing end and the second housing end, the through holes 210, 450, 250 are arranged on the same straight line along the longitudinal direction of the housing. The rod-shaped member 20 is inserted into each of the through holes 210, 450, 250 in the vicinity of each of the first housing end and the second housing end. The rod-shaped member 20 is, for example, a screw member.

  Specifically, in the vicinity of each of the first housing end and the second housing end, the rod-like member 20 is screwed into each of the through holes 210, 450, and 250, so that the base 201 and the cover 200 and the base 400 are firmly integrated. That is, the rod-shaped member 20 is an integrated member for integrating the base 201, the cover 200, and the base 400. That is, the rod-shaped member 20 is an integrated member that penetrates at least one of the cover 200 and the base 400 and integrates at least the cover 200 and the base 400.

  In other words, in the part where a part of the cover 200 and a part of the base 400 overlap and the part where the part of the base 201 overlaps, the base 201, The cover 200 and the base 400 are integrated. That is, at a portion where a part of the cover 200 and a part of the base 400 overlap each other, at least one of the cover 200 and the base 400 is integrated through at least one of the cover and the base. Therefore, the cover 200 and the base 400 are integrated by the integrated member.

  As described above, according to the present embodiment, in the part where a part of the cover 200 and a part of the base 400 overlap and the part of the base 201 overlap, The base 201, the cover 200, and the base 400 are integrated by the rod-shaped member 20.

  Therefore, the base 201, the cover 200, and the base 400 can be firmly integrated with the rod-shaped member 20 without using an adhesive or the like. Therefore, the base 201, the cover 200, and the base 400 can be firmly integrated with a simple configuration. Thereby, the base 201, the cover 200, and the base 400 can be integrated, that is, the lamp 100 can be easily assembled.

  Further, the base 201 is fixed to the integrated end portion of the cover 200 and the base 400 at a portion where a part of the cover 200 and a part of the base 400 overlap. Therefore, the cover 200 and the base 400 can be firmly integrated. Therefore, it is possible to make it difficult for the cover 200 to come off the base 400.

  Further, the thickness of the cover 200 in the longitudinal direction of the cover 200 is t1, and the thickness of the end plate 211a is t2. In this case, it is preferable that t1 ≦ t2. As described above, when the thickness of the end plate 211a serving as the fixing portion with the base 201 is increased while reducing the thickness in the longitudinal direction of the cover 200 that can be the emission surface, the fixing portion is secured while ensuring sufficient transmittance. Thus, it is possible to obtain a straight tube type LED lamp in which the strength of the cover is maintained.

  However, the thickness of the cover 200 is not particularly limited, and may be appropriately designed in consideration of the strength at the fixing portion and the balance of the weight of the entire lamp.

  Specifically, in the vicinity of the side surface of the base 201, the bar-shaped member 23 is screwed into each of the through holes 215, 255, 355, 455, and 215, so that the base 201, the cover 200C, the base 400, and the LED module. 300D is firmly integrated. That is, the rod-shaped member 23 is an integrated member for integrating the base 201, the cover 200C, the base 400, and the LED module 300D.

  In other words, in the part where a part of the cover 200C and a part of the base 400 overlap, the part of the light emitting module (LED module 300D) and the part of the base 201 overlap, The base 201, the cover 200 </ b> C, the base 400, and the light emitting module are integrated by the adjusting member (rod-shaped member 23).

  Therefore, the base 201, the cover 200 </ b> C, the base 400, and the LED module 300 </ b> D can be firmly integrated with the rod-shaped member 23 without using an adhesive or the like. Therefore, the base 201, the cover 200C, the base 400, and the LED module 300D can be firmly integrated with a simple configuration. Thereby, integration of the base 201, the cover 200C, the base 400, and the LED module 300D, that is, the assembly of the lamp 100C can be easily performed.

  Further, in the modification example F, the cover 200C can be made difficult to come off from the base 400 as in the first embodiment.

<Modification G>
In the above embodiment, the LED module is a COB type (Chip On Board) in which the LED itself (bare chip) is directly mounted on the substrate.

  However, the LED module is a package type in which an LED chip is mounted in a cavity molded with resin or the like and the inside of the cavity is sealed with a phosphor-containing resin, that is, a surface mount type (SMD). Also good.

  Such an SMD type LED module 300E according to Modification G of the present invention will be described below.

  FIG. 17 is a perspective view of an LED module 300E according to Modification G.

  As shown in FIG. 17, in the LED module 300E, a plurality of packages 390 are linearly mounted in a line on the surface of the substrate 310.

  Package 390 is made of ceramics, resin, or the like, and LED 321 is mounted in the cavity. The mounted LED 321 is covered with a sealing member 322. The plurality of packages 390 are electrically connected to each other by a wiring pattern, a wire, and the like.

  When the LED module 300E in which a plurality of packages 390 are arranged in this way is adopted, the packages themselves are individually lit, so when visually observed, the individual packages are lit independently, i.e., they feel a crushing feeling. There are things to do. Such a crushing feeling is often regarded as a problem in forming a linear light source.

  From the viewpoint of eliminating the crushing feeling, it is preferable to collectively seal the plurality of packages 390 with a transparent resin. The transparent resin is not particularly limited, such as a silicone resin, and any resin having high heat resistance may be used. The transparent resin may contain a wavelength conversion member that converts the wavelength with light generated from the LED package.

<Modification H>
In the above embodiment, the shape of the cap pin 202 is a straight line, but is not limited thereto.

  As shown in FIG. 18, the shape of the tip of the base pin 202 according to the modification H may be L-shaped. With this configuration, it is possible to make it difficult for the lamp having the cap pin 202 according to the modification H to be detached from the lighting fixture.

<Modification J>

  FIG. 19 is a diagram illustrating a configuration of a base 201 according to Modification I.

  As shown in FIG. 19, the base 201 according to Modification J is different from the base 201 of FIG. 1 in that it includes a base pin 202 b instead of a pair of base pins 202.

  The base pin 202b is a ground pin for grounding. The shape of one end of the cap pin 202b is, for example, a T-shape so as to be attached to a lighting fixture. The other end of the cap pin 202b is electrically connected to, for example, a ground terminal (not shown) in the housing 110 via a wiring.

  As mentioned above, although the lamp | ramp and illuminating device of this invention were demonstrated based on embodiment, this invention is not limited to these embodiment. The present invention includes various modifications made by those skilled in the art without departing from the scope of the present invention. Moreover, you may combine each component in several embodiment arbitrarily in the range which does not deviate from the meaning of invention.

  For example, among the plurality of through holes into which the rod-shaped members are inserted, the through hole into which the rod-shaped member is inserted last may be a hole that does not penetrate the end plate. For example, a hole that does not penetrate through the end plate 211a may be formed in the end plate 211a of FIG.

  Moreover, the rod-shaped member of the said embodiment or modification is not limited to a screw member. The rod-shaped member may be, for example, a member (hereinafter, also referred to as a both-end fixing member) in which a flat fixing member that can be attached and detached is formed at both ends of a rod-shaped metal.

  In this case, the rod-shaped metal of the both-ends fixing member is inserted into the through holes 210, 450, 250 in FIG. Then, a fixing member is attached to one end of the bar-shaped metal projecting outside the base 201 and the other end of the bar-shaped metal projecting inside the cover 200. Even in such a configuration using both end fixing members, the base 201, the cover 200, and the base 400 can be firmly integrated.

  Further, although the base covers the outer surfaces of the longitudinal ends of both the cover and the base, it is not limited to this. The base may be configured to cover the outer surface of the longitudinal end of either the cover or the base.

  In the above embodiment, the plurality of LEDs 321 on the substrate 310 of the LED module 300 are collectively sealed by the common sealing member 322. However, each of the plurality of LEDs 321 may be individually sealed by another sealing member 322.

  In the above-described embodiment, a single-sided power supply type lamp that is fed from one end of the housing 110 has been described. However, a double-sided feed type that is fed from both ends of the housing 110 may be used.

  Moreover, although LED was illustrated as a semiconductor light-emitting device in the said embodiment, a semiconductor laser and organic EL (Electro Luminescence) may be sufficient.

  In the above embodiment, the substrate 310 having a rectangular cross-sectional shape is used. However, a polygonal substrate having a cross-sectional shape other than a square (rectangular) may be used. That is, the shape of the substrate 310 may be a triangular prism, a pentagonal prism, a hexagonal prism, or the like.

  In addition, although the base 201 according to the above-described embodiment is configured by one integrated housing, the present invention is not limited to this. The base according to the above embodiment may be composed of, for example, two housings having a semicircular cross section.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
