(Knowledge that became the basis of the present invention)
The present inventor has found that the following problems occur with respect to the lighting device described in the “Background Art” column.

  For example, the case where an illuminating device is used as an emergency lamp at the time of a power failure is assumed. In particular, when a power outage occurs due to a disaster such as an earthquake, a person is required to evacuate outdoors in order to escape from the collapse of a house.

  At this time, the lighting device is used to irradiate the door serving as an entrance and the vicinity thereof in order to guide evacuation. Furthermore, the lighting device is disposed above the door in order to prevent the evacuation from being hindered. In this case, the illuminating device is required to irradiate the vicinity immediately below to irradiate the door and the vicinity thereof.

  In the conventional illumination device, a light source is attached to the tip of a mast that can be vertically expanded and contracted, and the irradiation position and the irradiation angle can be changed. However, there is a limit to the irradiation angle that can be changed. For example, a conventional lighting device cannot irradiate the vicinity immediately below.

  Therefore, in order to solve such a problem, a lighting device according to one embodiment of the present invention is attached to a light source unit, a housing unit having an inclined surface inclined from an upper surface to a side surface, and the inclined surface, A support unit that supports the light source unit, and the support unit supports the light source unit so that the light source unit and the inclined surface are separated from each other, and the light source unit is movable at least in the vertical direction. The light source unit does not contact the inclined surface when moved to the maximum in the downward direction.

  Thereby, a desired light distribution can be obtained and a desired direction can be irradiated. Therefore, for example, it is possible to irradiate the vicinity immediately below the illumination device.

  Below, the illuminating device which concerns on embodiment of this invention is demonstrated in detail using drawing. Note that each of the embodiments described below shows a preferred specific example of the present invention. Therefore, the numerical values, shapes, materials, components, component arrangements, connection forms, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. Therefore, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims showing the highest concept of the present invention are described as optional constituent elements.

  Each figure is a mimetic diagram and is not necessarily illustrated strictly. Moreover, in each figure, the same code | symbol is attached | subjected about the same structural member.

  In the following embodiments, an emergency lamp will be described as an example of a lighting device.

Specifically, in the following description, the direction parallel to the X axis shown in FIG. 1 may be described as the left-right direction, the direction parallel to the Y axis as the vertical direction, and the direction parallel to the Z axis as the front-back direction.

  Hereinafter, each component and connection form of the emergency lamp 10 will be described with reference to FIGS.

[LED lamp]
First, the LED lamp 100 will be described using FIG. 4 with reference to FIGS. FIG. 4 is an exploded perspective view showing the LED lamp 100 according to the present embodiment.

  The LED lamp 100 is an example of a light source unit of the emergency lamp 10. The LED lamp 100 is, for example, a halogen bulb-type LED lamp (LED bulb) with a reflector that is an alternative to a halogen bulb with a reflector. The LED lamp 100 is attached to the inclined surface 411 of the housing part 400 via the support part 500.

  As shown in FIG. 4, the LED lamp 100 includes, for example, an LED module 110, a light guide member 120, a front cover 130, a support base 140, and a holding case 150.

  The LED module 110 is an example of a light emitting module having a light emitting element, and emits light of a predetermined color (wavelength) such as white. For example, the LED module 110 includes a base 111 and an LED element 112. The LED module 110 emits light by electric power supplied from a drive circuit configured by a plurality of circuit elements mounted on the drive circuit unit 300.

  The base 111 is an LED mounting board for mounting the LED element 112. The base 111 is, for example, a ceramic substrate made of ceramics such as alumina, a resin substrate made of resin, or a metal base substrate that is insulation-coated with a metal as a base. The base 111 may be made of a material having high thermal conductivity.

  In addition, metal wiring for electrically connecting the plurality of LED elements 112 is patterned on the surface of the base 111. Further, the base 111 is formed with a pair of electrode terminals (feeding terminals) connected to the metal wiring. The pair of electrode terminals is electrically connected to the drive circuit unit 300 by a pair of lead wires (cables) or the like, and receives DC power supplied to the LED element 112.

  The LED element 112 is a packaged SMD (Surface Mount Device) type LED element. The LED element 112 includes, for example, a container having a recess, an LED chip mounted in the recess, and a sealing member sealed in the recess.

  The LED chip is a semiconductor light emitting element that emits light with a predetermined power, and is a bare chip that emits monochromatic visible light. In this embodiment, a blue LED chip that emits blue light when energized is used. The blue LED chip is a semiconductor light emitting element configured by forming a semiconductor layer made of an InGaN-based material on a sapphire substrate, for example. Specifically, as the blue LED chip, a gallium nitride based semiconductor light emitting device having a central wavelength of 440 nm to 470 nm can be used.

  The sealing member is mainly composed of a translucent material. At this time, when it is necessary to convert the wavelength of the light of the LED chip into a predetermined wavelength, a wavelength conversion material is mixed into the translucent material. The sealing member in the present embodiment is a wavelength conversion member that includes a phosphor as a wavelength conversion material and converts the wavelength (color) of light emitted from the LED chip. As such a sealing member, for example, an insulating resin material (phosphor-containing resin) containing phosphor particles can be used. The phosphor particles are excited by light emitted from the LED chip and emit light of a desired color (wavelength).

  As a translucent resin material constituting the sealing member, for example, a silicone resin can be used. Further, as the phosphor particles to be contained in the sealing member, for example, when the LED chip is a blue LED chip, in order to obtain white light, for example, YAG (yttrium, aluminum, garnet) -based yellow phosphor particles are used. Can be used. Thereby, a part of blue light emitted from the LED chip is wavelength-converted into yellow light by the yellow phosphor particles contained in the sealing member. And the blue light which was not absorbed by the yellow fluorescent substance particle and the yellow light wavelength-converted by the yellow fluorescent substance particle are mixed, and white light radiates | emits from a sealing member.

  The light guide member 120 is a member that guides light emitted from the LED module 110. The light guide member 120 has a light emitting surface 121 exposed to the outside of the lamp, and emits the guided light from the light emitting surface 121 to the outside of the lamp. The light emission direction is the normal direction of the light emission surface 121, specifically, the direction (the vertical direction on the paper surface) indicated by the lamp axis J shown in FIG.

  For example, the light guide member 120 is made of a translucent material. Specifically, as the light guide member 120, a light-transmitting resin material or a glass material can be used.

  The front cover 130 is an example of a cover member configured to surround the light guide member 120. For example, the front cover 130 is a truncated cone-shaped cylinder and is fixed to the holding case 150. The front cover 130 is made of, for example, a light shielding material. For example, as the front cover 130, a resin material such as polybutylene terephthalate (PBT) can be used.

  The support base 140 (module plate) is a support member that supports the LED module 110. The support base 140 is a cap-shaped member that includes the flat plate portion 141 on which the LED module 110 is placed and covers the opening of the holding case 150.

  As shown in FIG. 4, the flat plate portion 141 is provided with a through hole 142. For example, a cable that electrically connects the drive circuit unit 300 and the LED module 110 is inserted through the through hole 142. Thereby, electric power can be supplied to the LED module 110.

  The support table 140 can directly conduct the heat generated from the LED module 110 and conducted to the support table 140 to the holding case 150 by contacting the holding case 150. Thus, the support stand 140 also functions as a heat radiating member (heat sink).

  The support stand 140 is made of, for example, a metal material mainly composed of aluminum (Al), copper (Cu), iron (Fe), or the like, or a resin material having high thermal conductivity. Thereby, the support stand 140 can conduct heat efficiently.

  The holding case 150 is an outer member configured to cover the LED module 110 together with the front cover 130. For example, the holding case 150 is a bottomed cylindrical member. The light emitting surface 121, the front cover 130, and the holding case 150 of the light guide member 120 form an outline of the LED lamp 100. For example, as the holding case 150, an insulating resin material such as PBT can be used.

  As shown in FIG. 4, the holding case 150 has a through hole 151 on the bottom surface. For example, a cable that electrically connects the drive circuit unit 300 and the LED module 110 is inserted into the through hole 151.

  The holding case 150 is provided with a hole 152. The holding case 150 is supported by the support portion 500 when a screw is inserted into the hole portion 152. The support of the holding case 150 (LED lamp 100) by the support unit 500 will be described in detail later.

[Accommodation of drive circuit section and battery section]
Subsequently, an example of housing the drive circuit unit 300 and the battery unit 200 will be described with reference to FIGS.

  9 and 10 are partially exploded perspective views for explaining the connection relationship between the front case 410 and the drive circuit unit 300 according to the present embodiment. FIG. 11 is a partially exploded perspective view for explaining the connection relationship between the front case 410 and the back case 420 according to the present embodiment. FIG. 12 is a cross-sectional view illustrating an example of housing the drive circuit unit 300 and the battery unit 200 according to the present embodiment.

  When housing the battery unit 200 and the drive circuit unit 300 in the housing unit 400, for example, first, the button circuit board 320 is fixed to the front case 410.

  For example, as shown in FIG. 9, the third protrusions 415 are inserted into holes formed at the four corners of the button circuit board 320. Specifically, the small diameter portion at the tip of the third protrusion 415 is inserted into the hole of the button circuit board 320. At this time, the first main surface of the button circuit board 320 contacts the step formed by the small diameter portion and the large diameter portion of the third protrusion 415. The first main surface is the front case 410 side, that is, the front surface, for example, a surface on which circuit elements are mounted.

  Further, the locking portion 416 is inserted into a through hole provided in the button circuit board 320. The claw portion provided at the tip of the locking portion 416 contacts the second main surface of the button circuit board 320. That is, the claw portion and the step between the third projecting portion 415 sandwich the button circuit board 320. The second main surface is a surface opposite to the first main surface, that is, a rear surface.

  As a result, the button circuit board 320 is fixed to the front case 410 as shown in FIG. At this time, as shown in FIG. 12, the button circuit board 320 is accommodated in a space formed by the convex surface portion 412.

  Next, the drive circuit board 310 is fixed to the front case 410.

  For example, as shown in FIG. 10, the second protrusions 414 are inserted into holes formed at the four corners of the drive circuit board 310. Specifically, the small diameter portion at the tip of the second protrusion 414 is inserted into the hole of the drive circuit board 310. At this time, the first main surface of the drive circuit board 310 contacts the step formed by the small diameter portion and the large diameter portion of the second protrusion 414. The first main surface is the front case 410 side, that is, the front surface, and is a surface on which main circuit elements are mounted, for example. Main circuit elements are large circuit elements such as capacitors and choke coils.

  As shown in FIG. 10, the drive circuit board 310 is fixed by the second screw 440. The shaft of the second screw 440 is inserted into the hole of the drive circuit board 310 and the hole provided in the second protrusion 414 from the second main surface side, which is the surface opposite to the first main surface. . That is, the neck of the second screw 440 contacts the second main surface of the drive circuit board 310. As described above, the neck of the second screw 440 and the step of the second protrusion 414 sandwich the drive circuit board 310.

  Thus, the drive circuit board 310 is fixed to the front case 410 as shown in FIG. At this time, as shown in FIG. 12, the circuit elements provided on the drive circuit board 310 are accommodated in the space formed by the convex surface portion 412.

  Next, after the battery unit 200 is accommodated in the back case 420, the front case 410 and the back case 420 are fixed.

  For example, as shown in FIG. 11, the first protrusion 413 of the front case 410 is inserted into the hole 421 of the back case 420 and fixed by the first screw 430. Specifically, the first protrusion 413 is inserted into the hole 421 from the front side of the back case 420, and the first screw 430 is inserted into the hole 421 from the back side.

  Here, the details of the hole 421 will be described with reference to FIG. As shown in FIG. 12, the hole portion 421 includes a first large diameter portion 421a, a small diameter portion 421b, and a second large diameter portion 421c (counterbore portion).

  The first large diameter portion 421a is a portion that is located on the front case 410 side (front side) and into which the first protrusion 413 is inserted. The tip of the first protrusion 413 contacts the step surface formed by the first large diameter portion 421a and the small diameter portion 421b. The diameter of the first large diameter portion 421a is substantially the same as the diameter of the first protruding portion 413 and is larger than the diameter of the small diameter portion 421b.

  The small diameter portion 421b is a portion that is located in the central region of the hole portion 421 and through which the shaft of the first screw 430 is inserted. The diameter of the small diameter part 421b is substantially the same as the diameter of the shaft of the first screw 430, and is smaller than the diameter of the first large diameter part 421a and the diameter of the second large diameter part 421c.

  The second large diameter portion 421c is located on the back side and is a portion where the head of the first screw 430 is inserted, that is, a counterbore portion. The neck of the first screw 430 contacts the step surface formed by the second large diameter portion 421c and the small diameter portion 421b. The diameter of the second large diameter portion 421c is substantially the same as the diameter of the head of the first screw 430 and is larger than the diameter of the small diameter portion 421b.

  Accordingly, as shown in FIG. 12, the front case 410 and the back case 420 can be fixed by sandwiching the small-diameter portion 421b between the neck of the first screw 430 and the tip of the first protrusion 413. .

  At this time, as shown in FIG. 12, the battery unit 200 and the drive circuit board 310 are separated to ensure insulation. That is, the battery unit 200 is sandwiched and fixed between the inner surface (for example, rib-shaped protrusion) of the front case 410 and the inner surface of the back case 420 (inner surface of the back surface portion). Therefore, the battery unit 200 is restricted from moving in the front-rear direction of the housing unit 400 so as not to contact the drive circuit board 310.

  At this time, for example, the rib-shaped protrusion provided on the inner surface of the front case 410 is higher than the second protrusion 414. That is, the rib-like protrusion has a longer length in the protruding direction than the second protruding portion 414. As a result, the drive circuit board 310 fixed to the second projecting portion 414 and the battery portion 200 in contact with the rib-like projection can be separated from each other.

  Although not shown, the battery unit 200 and the drive circuit board 310 are electrically connected by a lead wire for transmitting power from the battery unit 200. Similarly, the drive circuit board 310 and the button circuit board 320 are electrically connected by lead wires for transmitting an electric signal from the button circuit board 320. In addition, a cable for supplying DC power generated by the drive circuit board 310 to the LED lamp 100 is connected to the drive circuit board 310.

In other words, the support part 500 supports the LED lamp 100 such that the rotation axis of the LED lamp 100 and the rotation axis of the support part 500 are different. Specifically, the support unit 500 supports the LED lamp 100 so that the LED lamp 100 can rotate about a direction parallel to the inclined surface 411 as a rotation axis.

  Moreover, the support part 500 supports the LED lamp 100 so that at least a part of the LED lamp 100 protrudes outward from the housing part 400 when the emergency lamp 10 is viewed in plan. For example, as illustrated in FIG. 2A, the rotation axis of the LED lamp 100 protrudes from the outside of the housing unit 400. It should be noted that at least a part of the LED lamp 100 may always protrude outward from the casing 400, or may protrude outward from the casing 400 only at a predetermined rotational position.

  As shown in FIG. 13, the support unit 500 includes a support 510, a hollow bolt 520, first washers 530 and 531, a nut 540, a third screw 550, and second washers 560 and 561.

The second flat plate portion 512 is provided with a through hole 512a. The shaft of the third screw 550 is inserted through the through hole 512a. The shaft of the third screw 550 is also inserted through the hole 152 of the LED lamp 100. The through hole 512a is formed by, for example, press working. At this time, either the formation of the through hole 512a or the formation of the second flat plate portion 512 by bending may be performed first.

  Thereby, the support body 510 supports the LED lamp 100 rotatably. That is, the LED lamp 100 can rotate with the axial direction of the third screw 550 as the rotation axis.

  The axial direction of the third screw 550 is parallel to the inclined surface 411. That is, the rotation direction of the LED lamp 100 and the rotation direction of the support 510 are orthogonal to each other. Therefore, the LED lamp 100 can irradiate all directions.

  The third flat plate portion 513 is a portion that connects the first flat plate portion 511 and the second flat plate portion 512. The third flat plate portion 513 is inclined with respect to the first flat plate portion 511 and the second flat plate portion 512.

  Note that the support 510 may have a U shape with a substantially right angle.

For example, a cable for electrically connecting the LED module 110 of the LED lamp 100 and the drive circuit unit 300 is inserted into the through hole of the hollow bolt 520. Thereby, the electric power produced | generated by the drive circuit part 300 can be supplied to the LED lamp 100, and the LED lamp 100 can be made to light.

  The first washers 530 and 531 are provided to suppress loosening of the hollow bolt 520. The first washer 530 is provided between the head of the hollow bolt 520 and the support 510, and the first washer 531 is provided between the support 510 and the inclined surface 411 of the front case 410. The first washers 530 and 531 are made of, for example, a metal material or a resin material.

  As described above, the support unit 500 is rotatable by itself. Specifically, the support 510 can rotate about a direction perpendicular to the inclined surface 411 as a rotation axis. The first washers 530 and 531 suppress the loosening of the hollow bolt 520 and the falling of the support portion 500 when the support body 510 rotates.

  Specifically, as shown in FIG. 14A, the support unit 500 can rotate about a direction perpendicular to the inclined surface 411 as a rotation axis. Thereby, for example, as shown in FIGS. 14B and 14C, the support unit 500 can freely irradiate the left and right directions or the oblique directions of the emergency lamp 10.

  The nut 540 is an example of a member for attaching the support body 510 to the front case 410. The nut 540 fixes the support body 510 by tightening the shaft of the hollow bolt 520 from the inner surface side of the front case 410. The nut 540 is, for example, a hex nut. The nut 540 is made of, for example, a metal material or a resin material.

  The third screw 550 is an example of a member for attaching the LED lamp 100 to the support 510. Specifically, the shaft of the third screw 550 is inserted through the second washer 560, the through hole 512a of the support 510, the second washer 561, and the hole 152 of the LED lamp 100 in this order. The third screw 550 is made of, for example, a metal material or a resin material.

  The second washers 560 and 561 are provided to suppress loosening of the third screw 550. The second washer 560 is provided between the head of the third screw 550 and the support 510, and the second washer 561 is provided between the support 510 and the holding case 150 of the LED lamp 100. The second washers 560 and 561 are made of, for example, a metal material or a resin material.

  Specifically, the LED lamp 100 is rotatable about the direction in which the second flat plate portion 512 faces, that is, the sandwiched direction, as the rotation axis. The second washers 560 and 561 suppress the loosening of the third screw 550 and the LED lamp 100 from falling off when the LED lamp 100 rotates.

  As shown in FIG. 15A, the LED lamp 100 is rotatable about two third screws 550 as a rotation axis. That is, the LED lamp 100 can be rotated about the third screw 550 as a rotation axis so as not to contact the inclined surface 411.

  In addition, the hole part 611, the attachment hole 621, and the through-hole 622 are formed by press work, for example. Further, the number, position, and shape of the hole portion 611, the mounting hole 621, and the through hole 622 are not limited to those described above. For example, the hole 611, the attachment hole 621, and the through hole 622 may be rectangular holes or through holes, and a plurality of holes may be provided.

[Summary]
As described above, in the emergency lamp 10 according to the present embodiment, the LED lamp 100, the casing 400 having the inclined surface 411 inclined from the upper surface to the side surface, and the inclined surface 411 are attached to the LED lamp 100. A support unit 500 that supports the LED lamp 100 so that the LED lamp 100 and the inclined surface 411 are separated from each other and the LED lamp 100 is movable at least in the vertical direction. The lamp 100 does not come into contact with the inclined surface 411 when the lamp 100 is moved to the maximum in the downward direction.

  Thus, the LED lamp 100 is attached to the inclined surface 411 via the support portion 500 so as not to come into contact with the inclined surface 411. Therefore, the LED lamp 100 irradiates the lower part including the vicinity immediately below the emergency lamp 10. Can do. Specifically, the LED lamp 100 irradiates the lower side when attached to the inclined surface 411 than when attached to the upper surface of the housing part 400 via the support part 500. Can do. Therefore, a more desired light distribution can be obtained.

  Accordingly, the support unit 500 supports the LED lamp 100 so that the support unit 500 can rotate in a direction different from the rotation direction of the support unit 500 and can irradiate various directions. Therefore, the emergency lamp 10 can obtain a wide range of light distribution characteristics with a simple component configuration.

  Further, in the emergency lamp 10 according to the present embodiment, the support unit 500 can rotate with a direction perpendicular to the inclined surface 411 as a rotation axis, and the LED lamp 100 has a direction parallel to the inclined surface 411 as a rotation axis. The LED lamp 100 is supported so as to be rotatable.

  Thereby, since the rotation direction of the support part 500 and the rotation direction of the LED lamp 100 are orthogonal, it can irradiate all directions.

  In the emergency lamp 10 according to the present embodiment, the support unit 500 supports the LED lamp 100 so that at least a part of the LED lamp 100 protrudes outward from the housing unit 400 when viewed in plan. To do.

  Thereby, since at least a part of the LED lamp 100 protrudes outward from the housing portion 400, it is possible to irradiate a region closer to the area immediately below the emergency lamp 10.

  Moreover, in the emergency lamp 10 according to the present embodiment, the emergency lamp 10 is further mounted on a mounting surface for mounting the emergency lamp 10 provided on the back surface portion of the housing portion 400.

  Moreover, the back case 420 does not need to have an upper surface. That is, the inclined surface 411 may be a surface inclined from the upper end of the back surface of the back case 420 (corresponding to the upper surface of the housing unit 400) to the front surface.

  Moreover, although the said embodiment demonstrated the example which fixes the front case 410 and the back case 420 with the 1st screw 430, it is not restricted to this. For example, each of the front case 410 and the back case 420 may be provided with a locking portion that physically locks each other.

  Moreover, although the said embodiment demonstrated the example which the support body 510 is substantially U shape, it does not restrict to this. For example, the support 510 may be substantially V-shaped. The support 510 only needs to be able to support the LED lamp 100 so as to be movable in the vertical direction.

  For example, the support 510 is a rod-shaped member that can be expanded and contracted in a direction perpendicular to the inclined surface 411, and the LED lamp 100 may be provided at the tip. By extending the extendable rod-like support 510, the LED lamp 100 provided at the tip protrudes outward from the housing portion 400, so that the area directly below the emergency lamp 10 can be irradiated.

  Further, the accommodation example of the drive circuit unit 300 and the battery unit 200 described in the above embodiment is an example, and is not limited to the above. For example, the drive circuit unit 300 may be fixed to the back case 420. Further, the drive circuit unit 300 and the battery unit 200 may be arranged side by side in the left-right direction or the up-down direction.

  Moreover, although the emergency lamp 10 demonstrated the example provided with the two LED lamps 100 and the two support parts 500 in the said embodiment, it is not restricted to this. The emergency lamp 10 may include only one LED lamp 100 and the support unit 500, or may include three or more LED lamps 100 and the support unit 500. Further, only one support portion 500 may support the plurality of LED lamps 100.

  Similarly, although the emergency lamp 10 is provided with the two attachment bodies 600, it is not restricted to this. The emergency lamp 10 may include only one mounting body 600, or may include three or more mounting bodies 600.

  In the above embodiment, the case where the LED module 110 is an SMD type LED module using a packaged LED element has been described, but the present invention is not limited thereto. The LED module 110 may be a COB (Chip On Board) type LED module in which a plurality of LED chips are directly mounted on a substrate, and the plurality of LED chips are collectively sealed with a phosphor-containing resin.

  Two or more substrates (LED modules 110) placed on the support base 140 may be arranged. In this case, metal wiring provided on each substrate may be connected via the connection terminal.

  In the above embodiment, the LED module 110 is configured to emit white light by the blue LED chip and the yellow phosphor. However, the present invention is not limited to this. For example, in order to improve color rendering properties, a red phosphor and a green phosphor may be further mixed in addition to the yellow phosphor. Moreover, you may make it discharge | release white light by combining with a blue LED chip | tip using the fluorescent substance containing resin containing a red fluorescent substance and a green fluorescent substance, without using yellow fluorescent substance.

  Moreover, in said embodiment, you may use the LED chip which light-emits colors other than blue as an LED chip. For example, when an ultraviolet light emitting LED chip is used, a combination of phosphor particles that emit light in three primary colors (red, green, and blue) can be used as the phosphor particles. Furthermore, a wavelength conversion material other than the phosphor particles may be used. For example, the wavelength conversion material absorbs light of a certain wavelength such as a semiconductor, a metal complex, an organic dye, or a pigment, and has a wavelength different from the absorbed light. A material containing a substance that emits light may be used.

  In the above embodiment, the LED is exemplified as the light emitting element. However, a semiconductor light emitting element such as a semiconductor laser, a light emitting element such as an organic EL (Electro Luminescence), or an inorganic EL may be used.

  In the above embodiment, the LED module 110 is configured to emit white light, but is not limited thereto. For example, the LED module 110 may be configured to emit color light such as red or blue. By using such an LED module of a color light source, the lighting effect can be improved.

  In the above embodiment, the LED lamp 100 is an example of a halogen bulb-type LED lamp that replaces the halogen bulb. However, the present invention is not limited to this. The LED lamp 100 can also be applied to lamps other than halogen bulbs.
