  Preferred embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example, and the present invention is not limited to this.

  As shown in FIG. 1, the LED lighting device 100 of the present invention includes a mounting plate 1 and an LED lamp main body 2, and a through hole 4 a having a diameter of 27 mm from which an external power supply line (F-cable) 3 protrudes is opened. The mounting plate 1 is screwed to the mounted portion 4 such as the ceiling surface, and the LED lamp body 2 is detachably mounted on the mounting plate 1. When the LED lamp body 2 is mounted on the mounting plate 1, the LED lamp body 2 and the external power line 3 are connected, and the LED lighting device 100 can be used as a downlight. If the hole has a diameter of 27 mm or less, no special reinforcement is applied to the ceiling, so that the LED lighting device can be attached with good workability.

  The mounting plate 1 is a substantially disc-shaped metal plate, the circular central surface portion 80b of the main body surface 80a is formed in a concave shape, and the insertion hole 80c of the external power supply wire 3 is opened at the central portion. The insertion hole 80c has an opening shape that can be rotated in the horizontal direction in a state where a rotation restricting portion 10d of the LED lamp body 2 described later is inserted. A pair of position fixing extension portions 80d are erected on the peripheral edge portion of the insertion hole 80c so as to face each other.

  A plurality of openings 80e are opened in the circumferential direction of the mounting plate main body surface 80a, and a locking tongue piece 8g is integrally formed with the main body surface 80a in the opening 8e. The locking tongue piece 80g is smaller than the opening of the opening 80e, and is integrated with the mounting plate 80a on the lower surface side of the mounting plate 1 so as to face the opening 80e on one end side of the radial peripheral edge of the opening 8e. Molded. The locking tongue piece 80a is formed with a claw portion 80h for preventing the rotational engagement from being released.

  As shown in FIGS. 2 to 4, the LED lamp body 2 includes a housing 10, an insulating cover 20, a quick connection terminal storage member 30, an LED unit member 40, a fixing member 50, a reflector 60, The light transmitting cover 70 is generally configured.

  The casing 10 is made of a material having high thermal conductivity such as aluminum, and has a flat cylindrical shape as a whole. Inside the housing 10, the insulating cover 20, the quick connection terminal storage member 30, the LED unit member 40, the fixing member 50, and the reflector 60 are stored, and the lower end opening is covered with the translucent cover 70.

  As shown in detail in FIGS. 5 and 6, the upper surface portion of the housing 10 is formed with a circular central surface portion 10a and an annular surface portion 10b with a step slightly higher than the central surface portion 10a. A power supply opening 10c is opened at the center. An elliptical plate-shaped rotation restricting portion 10d is formed in the periphery of the power supply opening 10c, and a pair of the power supply opening 10c is formed so as to stand up from the rotation restricting portion 10d. The LED lamp position fixing extension 10e is erected so as to face each other.

  The annular surface portion 10b has a plurality of insertion holes 10f in the circumferential direction in which the locking tongue pieces 80g of the mounting plate 1 are inserted. The piece 10g is formed so as to protrude into the insertion hole 10f. A locking claw (not shown) that engages with the claw portion 80h of the locking tongue piece 80g is formed at the lower surface side tip of the rotation locking piece 10g.

  An elastic member 11 such as a ring-shaped sponge is placed on the peripheral edge of the upper end of the housing 10. The elastic member 11 has a ring width that does not block the insertion hole 10f, and is in direct contact with the mounted portion 4 while being fitted to the outer peripheral portion of the mounting plate 1. The elastic member 11 can prevent dust, insects and the like from entering the LED lamp main body 2 and can absorb the vibration of the mounted member 4. In addition, a plurality of claw portions 10i are formed on the outer peripheral portion of the convex portion 10h, and are used when, for example, a hat-hat shaped hood or the like is attached to the housing 10.

  The insulating cover 20 is integrally formed of an insulating resin such as polycarbonate, and has a substantially disk shape as a whole as shown in FIGS. A pair of arcuate convex surface portions 20a are formed on the upper surface portion of the insulating cover 20, and an insertion hole 20b through which the external power supply wire 30 is inserted is opened in the central surface portion 20c.

  The quick connection terminal storage member 30 is made of an insulating resin such as polycarbonate, and as shown in FIGS. 2 to 4, an elliptical vertical cylindrical portion 30 a and the left and right sides of the vertical cylindrical portion 30 a. The extended elliptical plate-like bottom surface portion 30b is integrally formed. The vertical cylinder part 30a has an upper opening 30c and a lower opening 30d at a position corresponding to the bottom part 30b. Although not shown in detail here, the external power supply wire 3 is fast inside the vertical cylinder part 30a. The quick connection terminal to be connected is stored.

  As shown in detail in FIG. 11, the LED unit member 40 includes a disk-shaped substrate 40 a and a ring-shaped frame portion 40 b provided on the peripheral edge portion of the lower surface portion. The substrate 40a is a glass epoxy substrate or a high heat dissipation CEM3 in which copper foils are pasted on both upper and lower surfaces, and a plurality of LED elements 40c are arranged and mounted in a circle on the lower surface. On the same substrate 40a, an electronic component (not shown) of a lighting circuit that drives the LED element 40c to be lit is mounted. These electronic components may be mounted inside the frame portion 40b or may be disposed on the back surface portion of the substrate 40a. An insertion hole 40d for the external power supply wire 3 is opened at the center of the substrate 40a.

  Various known LEDs can be used as the LED element 40c. In this embodiment, a high-luminance type LED element that emits white light for illumination is used. The electronic components constituting the lighting circuit are well-known electronic components such as various diodes, capacitors, ICs, resistors for performing overcurrent protection, noise cut, rectification, smoothing, dimming control, and the like.

  A human sensor 41, an illuminance sensor 42, and an indicator 43 are mounted in parallel in the circumferential direction of the substrate 40a at the peripheral portion of the substrate 40a and at the cutout portion of the frame portion 40b. The human sensor 41 is a sensor that detects the presence of a human and may be either an active type or a passive type, but here, a passive type sensor is used. The illuminance sensor 42 is a sensor that detects ambient brightness, and blinks the LED element 40 c in conjunction with the human sensor 41. The indicator 43 displays the operating status of the human sensor 41, and displays ON / OFF of the operating switch of the human sensor 41 by emitting different colors. The indicator 41 can be omitted if it is not necessary. In this case, the configurations of the sensor accommodating portion 60c of the reflector 60 and the cutout portion 70c of the translucent cover 70 described below are changed correspondingly.

  A sensor control unit is installed on the substrate 40a. In the sensor control unit, the light-off operation of the illuminance sensor 42 is controlled by a method as shown in FIG. First, when the wall switch is ON, the indicator 43 is green and the human sensor 41 is ON. Further, when the wall switch is OFF, the indicator 43 is red, and the human sensor is OFF. When it is detected that the illuminance sensor 42 is below a predetermined illuminance while the human sensor 43 is ON, and the human sensor 41 detects the presence of a human, the LED element 40e is turned on. If a predetermined time (for example, 1 minute or more) elapses (or it is detected that the illuminance sensor 42 is equal to or greater than the predetermined illuminance) and the human sensor 41 does not detect the presence of a human, the LED element 40c is slowly turned off, It turns off completely after a predetermined time has elapsed (for example, after 3 seconds).

  In this embodiment, the human sensor 41, the illuminance sensor 42, and the indicator 43 are independently mounted on the substrate 40a. However, the human sensor 41, the illuminance sensor 42, and the indicator 43 are mounted on a dedicated sensor base. It is also possible to make a unit and mount the sensor base on the substrate 40a. In this case, the sensor base is designed so that the head of each sensor is at a predetermined height.

  The fixing member 50 locks an extension line (play line) of the external power supply wire 3 drawn from the lower opening 30d through the quick connection terminal accommodated in the quick connection terminal storage member 30, and the LED. It is a member that fixes the unit member 40 and the insulating cover 20 to the back surface portion of the housing 10 by screwing or the like from the back surface portion of the LED unit member 40. Although not shown in detail here, the fixing member 50 is an integrally molded product of an insulating resin in which a groove portion and a screw hole for locking an extension line of the external power source electric wire are formed. The external power supply wire 3 is connected to the power supply part of the substrate 40a.

  The reflector 60 is made of polycarbonate resin or the like that does not transmit light containing titanium oxide, and has a substantially umbrella-shaped disk shape as a whole. As shown in FIGS. 2 and 3, the reflector 60 has an opening formed at the center, an inner peripheral edge 60 a of the opening is an inclined surface, and a flange surface 60 b is formed on the outer side of the inner peripheral edge 60 a. It is integrally molded. A sensor accommodating portion 60 c is formed at a position corresponding to the mounting portion of the human sensor 41, the illuminance sensor 42, and the indicator 43 of the LED unit member 40 on the flange surface portion 60 b.

  The sensor housing portion 60c has a box shape with an upper surface portion opened, and is integrally formed so as to protrude toward the lower surface portion of the flange surface portion 60b. As shown in FIG. 10, a human sensor sensor window 60e, an illuminance sensor window 60f, and an indicator window 60g are opened on the lower surface 60d of the sensor housing 60c. The peripheral edge of the human sensor sensor window 60e has an enlarged tapered surface so that the outgoing angle of the outgoing beam from the human sensor 41 is not hindered. The sensor housing portion 60c is configured such that the lower surface portion 60d is substantially flush with the lower surface portion (irradiation surface portion) of the translucent cover 70 described later.

  The inner peripheral edge portion 60a of the reflector 60 and the lower surface portion (irradiation surface side) of the flange surface portion 60b are formed with a mirror-diffused reflective surface, and the irradiation efficiency is reflected by reflecting the light emitted from the LED element 40c without absorbing it. We are trying to improve.

  The translucent cover 70 is formed into a circular dome shape using polycarbonate or the like. The translucent cover 70 is formed by integrally forming a circular irradiation surface portion 70a and an extending portion 70b formed upright at the periphery thereof, and the reflector 60 in the irradiation surface portion 70a and the extending portion 70b. A cutout portion 70c is formed at a position corresponding to the sensor housing portion 60c.

  In the assembly of the LED lamp main body 2 described above, first, the quick connection terminal storage member 30 that stores the quick connection terminal is inserted from the inside of the housing 10 into the power supply unit 10 c of the housing 10. The quick connection terminal storage member 30 protrudes upward from the power supply opening 10c of the housing 10, and both side surfaces thereof are locked to the LED lamp position fixing extension 11e (FIG. 6).

  Next, after the insulating cover 20 and the LED unit member 40 are sequentially assembled in the housing 10, the LED unit member 40 and the insulating cover 20 are attached to the inner surface portion of the housing 10 by the fixing member 50 from the lower surface portion of the LED unit member 40. Secure with screws. Thereafter, the reflector 60 is assembled in the housing 10 and fixed with the housing 10 with screws or the like, and then the translucent cover 70 is fitted into the lower end opening of the housing 10 to complete the assembly.

  In this state, the convex surface portion 20 a of the insulating cover 20 is fitted into the concave portion on the back surface side where the annular surface portion 10 b of the upper surface portion of the housing 10 is formed, and the central surface portion 20 c is the back surface of the central surface portion 10 a of the housing 10. Contact the part.

  Further, the human sensor 41, the illuminance sensor 42, and the indicator 43 of the LED unit member 40 are accommodated in the sensor accommodating portion 60c of the reflector 60. At this time, the head of the human sensor 41 is located in the human sensor sensor window 60e of the lower surface portion 60d of the sensor housing portion, and the head of the illuminance sensor 42 is located in the illuminance sensor window 60f. The part is located in the indicator window 60g. The heads of the sensors 41 and 42 and the indicator 43 are arranged so as not to be exposed to the outside of the sensor housing portion lower surface portion 60d. However, depending on the case, all or one of the sensors 41 and 42 and the indicator 43 may be connected to each window. You may make it make a head protrude outside the part.

  Further, as apparent from FIGS. 9 to 11, the reflector 60 covers and hides the electronic components, the human sensor 41, the illuminance sensor 42, and the indicator 43 mounted on the peripheral portion of the LED unit member 40. Since these parts are not projected on 70, appearance is improved. When the electronic component is stored in the frame portion 40b of the LED unit member 40, the shielding effect of the electronic component is further enhanced. Note that the LED element 40 c mounted in a circle at the center of the LED unit member 40 is exposed from the opening of the reflector 60.

  On the other hand, as described above, the translucent cover 70 is fitted into the lower end opening of the housing 100. As shown in FIG. 8, the irradiation surface portion 70d of the translucent cover 70 and the lower surface portion 60d of the sensor housing portion 60c. Are substantially on the same plane. For this reason, the human sensor 41 and the illuminance sensor 42 are not affected by the reflected light of the reflector 60, and can thereby prevent malfunction. Moreover, since it looks integrated with the translucent cover 70, the appearance in appearance is also improved.

  The extension 70 b of the translucent cover 70 interferes with the peripheral edge of the reflector 60 to form a space between the translucent cover 70 and the reflector 60, and is reflected by the translucent cover 70. The reflected light is diffusely reflected by the lower surface portion of the reflector 60, and this is repeated, so that the light reaches the end portion side of the translucent cover 28. As a result, the entire surface of the translucent cover 28 including the portion covered by the reflector 60 is uniformly irradiated.

  The procedure for attaching such an LED lamp main body 2 to an attached portion such as a ceiling is roughly as follows. First, as shown in FIG. 1, the mounting plate 1 is inserted in a state where the external power supply wire 3 is inserted into the insertion hole 80c of the mounting plate 1 and the position fixing extension portion 80d is inserted into the through hole 4a of the mounted surface 4. Is fixed to the attached portion 4 by screws or the like.

  Next, the distal end portion of the external power supply wire 3 is inserted into the upper opening 30c of the quick connection terminal storage member 30 protruding from the upper surface portion of the LED lamp main body 2 and connected to the quick connection terminal. Thereafter, the LED lamp position fixing extension portion 10e and the rotation restricting portion 10d holding the quick connection terminal storage member 30 are inserted into the insertion hole 80c of the mounting plate 1, and the rotation locking piece of the LED lamp body 2 is inserted. When the LED lamp body 2 is rotated with 10 g inserted into the opening 80 e of the mounting plate 1 and the locking tongue piece 80 g of the mounting plate 1 inserted into the insertion hole 10 f of the LED lamp body 2, The tongue piece 80g engages with the claw portion of the rotation locking piece 10g of the LED lamp body 2. Thereby, the LED lamp main body 2 is attached to the attachment plate 1.

  In the present embodiment, the shape of the LED lamp main body 2 is a cylindrical shape, but is not limited thereto, and may be a flat polygonal column having a quadrangular cross section.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to these embodiment, Even if there is a design change of the range which does not deviate from the summary of this invention, it is included in this invention. That is, various changes and modifications that can be made by those skilled in the art are also included in the present invention.

A power supply opening 10c is opened at the center. An elliptical plate-shaped rotation restricting portion 10d is formed in the periphery of the power supply opening 10c, and a pair of the power supply opening 10c is formed so as to stand up from the rotation restricting portion 10d. The LED lamp position fixing extension 10e is erected so as to face each other.

  The annular surface portion 10b has a plurality of insertion holes 10f in the circumferential direction in which the locking tongue pieces 80g of the mounting plate 1 are inserted. The piece 10g is formed so as to protrude into the insertion hole 10f. A locking claw (not shown) that engages with the claw portion 80h of the locking tongue piece 80g is formed at the lower surface side tip of the rotation locking piece 10g.

  An elastic member 11 such as a ring-shaped sponge is placed on the peripheral edge of the upper end of the housing 10. The elastic member 11 has a ring width that does not block the insertion hole 10f, and is in direct contact with the mounted portion 4 while being fitted to the outer peripheral portion of the mounting plate 1. The elastic member 11 can prevent dust, insects and the like from entering the LED lamp main body 2 and can absorb the vibration of the mounted member 4. In addition, a plurality of claw portions 10i are formed on the outer peripheral portion of the convex portion 10h, and are used when, for example, a hat-hat shaped hood or the like is attached to the housing 10.

  The insulating cover 20 is integrally formed of an insulating resin such as polycarbonate, and has a substantially disk shape as a whole as shown in FIGS. A pair of arcuate convex surface portions 20a are formed on the upper surface portion of the insulating cover 20, and an insertion hole 20b through which the external power supply wire 30 is inserted is opened in the central surface portion 20c.

  The quick connection terminal storage member 30 is made of an insulating resin such as polycarbonate, and as shown in FIGS. 2 to 4, an elliptical vertical cylindrical portion 30 a and the left and right sides of the vertical cylindrical portion 30 a. The extended elliptical plate-like bottom surface portion 30b is integrally formed. The vertical cylinder part 30a has an upper opening 30c and a lower opening 30d at a position corresponding to the bottom part 30b. Although not shown in detail here, the external power supply wire 3 is fast inside the vertical cylinder part 30a. The quick connection terminal to be connected is stored.

  As shown in detail in FIG. 11, the LED unit member 40 includes a disk-shaped substrate 40 a and a ring-shaped frame portion 40 b provided on the peripheral edge portion of the lower surface portion. The substrate 40a is a glass epoxy substrate or a high heat dissipation CEM3 in which copper foils are pasted on both upper and lower surfaces, and a plurality of LED elements 40c are arranged and mounted in a circle on the lower surface. On the same substrate 40a, an electronic component (not shown) of a lighting circuit that drives the LED element 40c to be lit is mounted. These electronic components may be mounted inside the frame portion 40b or may be disposed on the back surface portion of the substrate 40a. An insertion hole 40d for the external power supply wire 3 is opened at the center of the substrate 40a.

  Various known LEDs can be used as the LED element 40c. In this embodiment, a high-luminance type LED element that emits white light for illumination is used. The electronic components constituting the lighting circuit are well-known electronic components such as various diodes, capacitors, ICs, resistors for performing overcurrent protection, noise cut, rectification, smoothing, dimming control, and the like.

  A human sensor 41, an illuminance sensor 42, and an indicator 43 are mounted in parallel in the circumferential direction of the substrate 40a at the peripheral portion of the substrate 40a and at the cutout portion of the frame portion 40b. The human sensor 41 is a sensor that detects the presence of a human and may be either an active type or a passive type, but here, a passive type sensor is used. The illuminance sensor 42 is a sensor that detects ambient brightness, and blinks the LED element 40 c in conjunction with the human sensor 41. The indicator 43 displays the operating status of the human sensor 41, and displays ON / OFF of the operating switch of the human sensor 41 by emitting different colors. The indicator 41 can be omitted if it is not necessary. In this case, the configurations of the sensor accommodating portion 60c of the reflector 60 and the cutout portion 70c of the translucent cover 70 described below are changed correspondingly.

  A sensor control unit is installed on the substrate 40a. In the sensor control unit, the light-off operation of the illuminance sensor 42 is controlled by a method as shown in FIG. First, when the wall switch is ON, the indicator 43 is green and the human sensor 41 is ON. Further, when the wall switch is OFF, the indicator 43 is red, and the human sensor is OFF. When it is detected that the illuminance sensor 42 is below a predetermined illuminance while the human sensor 43 is ON, and the human sensor 41 detects the presence of a human, the LED element 40e is turned on. If a predetermined time (for example, 1 minute or more) elapses (or it is detected that the illuminance sensor 42 is equal to or greater than the predetermined illuminance) and the human sensor 41 does not detect the presence of a human, the LED element 40c is slowly turned off, It turns off completely after a predetermined time has elapsed (for example, after 3 seconds).

  In this embodiment, the human sensor 41, the illuminance sensor 42, and the indicator 43 are independently mounted on the substrate 40a. However, the human sensor 41, the illuminance sensor 42, and the indicator 43 are mounted on a dedicated sensor base. It is also possible to make a unit and mount the sensor base on the substrate 40a. In this case, the sensor base is designed so that the head of each sensor is at a predetermined height.

  The fixing member 50 locks an extension line (play line) of the external power supply wire 3 drawn from the lower opening 30d through the quick connection terminal accommodated in the quick connection terminal storage member 30, and the LED. It is a member that fixes the unit member 40 and the insulating cover 20 to the back surface portion of the housing 10 by screwing or the like from the back surface portion of the LED unit member 40. Although not shown in detail here, the fixing member 50 is an integrally molded product of an insulating resin in which a groove portion and a screw hole for locking an extension line of the external power source electric wire are formed. The external power supply wire 3 is connected to the power supply part of the substrate 40a.

  The reflector 60 is made of polycarbonate resin or the like that does not transmit light containing titanium oxide, and has a substantially umbrella-shaped disk shape as a whole. As shown in FIGS. 2 and 3, the reflector 60 has an opening formed at the center, an inner peripheral edge 60 a of the opening is an inclined surface, and a flange surface 60 b is formed on the outer side of the inner peripheral edge 60 a. It is integrally molded. A sensor accommodating portion 60 c is formed at a position corresponding to the mounting portion of the human sensor 41, the illuminance sensor 42, and the indicator 43 of the LED unit member 40 on the flange surface portion 60 b.

  The sensor housing portion 60c has a box shape with an upper surface portion opened, and is integrally formed so as to protrude toward the lower surface portion of the flange surface portion 60b. As shown in FIG. 10, a human sensor sensor window 60e, an illuminance sensor window 60f, and an indicator window 60g are opened on the lower surface 60d of the sensor housing 60c. The peripheral edge of the human sensor sensor window 60e has an enlarged tapered surface so that the outgoing angle of the outgoing beam from the human sensor 41 is not hindered. The sensor housing portion 60c is configured such that the lower surface portion 60d is substantially flush with the lower surface portion (irradiation surface portion) of the translucent cover 70 described later.

  The inner peripheral edge portion 60a of the reflector 60 and the lower surface portion (irradiation surface side) of the flange surface portion 60b are formed with a mirror-diffused reflective surface, and the irradiation efficiency is reflected by reflecting the light emitted from the LED element 40c without absorbing it. We are trying to improve.

  The translucent cover 70 is formed into a circular dome shape using polycarbonate or the like. The translucent cover 70 is formed by integrally forming a circular irradiation surface portion 70a and an extending portion 70b formed upright at the periphery thereof, and the reflector 60 in the irradiation surface portion 70a and the extending portion 70b. A cutout portion 70c is formed at a position corresponding to the sensor housing portion 60c.

  In the assembly of the LED lamp main body 2 described above, first, the quick connection terminal storage member 30 that stores the quick connection terminal is inserted from the inside of the housing 10 into the power supply unit 10 c of the housing 10. The quick connection terminal storage member 30 protrudes upward from the power supply opening 10c of the housing 10, and both side surfaces thereof are locked to the LED lamp position fixing extension 11e (FIG. 6).

  Next, after the insulating cover 20 and the LED unit member 40 are sequentially assembled in the housing 10, the LED unit member 40 and the insulating cover 20 are attached to the inner surface portion of the housing 10 by the fixing member 50 from the lower surface portion of the LED unit member 40. Secure with screws. Thereafter, the reflector 60 is assembled in the housing 10 and fixed with the housing 10 with screws or the like, and then the translucent cover 70 is fitted into the lower end opening of the housing 10 to complete the assembly.

  In this state, the convex surface portion 20 a of the insulating cover 20 is fitted into the concave portion on the back surface side where the annular surface portion 10 b of the upper surface portion of the housing 10 is formed, and the central surface portion 20 c is the back surface of the central surface portion 10 a of the housing 10. Contact the part.

  Further, the human sensor 41, the illuminance sensor 42, and the indicator 43 of the LED unit member 40 are accommodated in the sensor accommodating portion 60c of the reflector 60. At this time, the head of the human sensor 41 is located in the human sensor sensor window 60e of the lower surface portion 60d of the sensor housing portion, and the head of the illuminance sensor 42 is located in the illuminance sensor window 60f. The part is located in the indicator window 60g. The heads of the sensors 41 and 42 and the indicator 43 are arranged so as not to be exposed to the outside of the sensor housing portion lower surface portion 60d. However, depending on the case, all or one of the sensors 41 and 42 and the indicator 43 may be connected to each window. You may make it make a head protrude outside the part.

  Further, as apparent from FIGS. 9 to 11, the reflector 60 covers and hides the electronic components, the human sensor 41, the illuminance sensor 42, and the indicator 43 mounted on the peripheral portion of the LED unit member 40. Since these parts are not projected on 70, appearance is improved. When the electronic component is stored in the frame portion 40b of the LED unit member 40, the shielding effect of the electronic component is further enhanced. Note that the LED element 40 c mounted in a circle at the center of the LED unit member 40 is exposed from the opening of the reflector 60.

  On the other hand, as described above, the translucent cover 70 is fitted into the lower end opening of the housing 100. As shown in FIG. 8, the irradiation surface portion 70d of the translucent cover 70 and the lower surface portion 60d of the sensor housing portion 60c. Are substantially on the same plane. For this reason, the human sensor 41 and the illuminance sensor 42 are not affected by the reflected light of the reflector 60, and can thereby prevent malfunction. Moreover, since it looks integrated with the translucent cover 70, the appearance in appearance is also improved.

  The extension 70 b of the translucent cover 70 interferes with the peripheral edge of the reflector 60 to form a space between the translucent cover 70 and the reflector 60, and is reflected by the translucent cover 70. The reflected light is diffusely reflected by the lower surface portion of the reflector 60, and this is repeated, so that the light reaches the end portion side of the translucent cover 28. As a result, the entire surface of the translucent cover 28 including the portion covered by the reflector 60 is uniformly irradiated.

  The procedure for attaching such an LED lamp main body 2 to an attached portion such as a ceiling is roughly as follows. First, as shown in FIG. 1, the mounting plate 1 is inserted in a state where the external power supply wire 3 is inserted into the insertion hole 80c of the mounting plate 1 and the position fixing extension portion 80d is inserted into the through hole 4a of the mounted surface 4. Is fixed to the attached portion 4 by screws or the like.

  Next, the distal end portion of the external power supply wire 3 is inserted into the upper opening 30c of the quick connection terminal storage member 30 protruding from the upper surface portion of the LED lamp main body 2 and connected to the quick connection terminal. Thereafter, the LED lamp position fixing extension portion 10e and the rotation restricting portion 10d holding the quick connection terminal storage member 30 are inserted into the insertion hole 80c of the mounting plate 1, and the rotation locking piece of the LED lamp body 2 is inserted. When the LED lamp body 2 is rotated with 10 g inserted into the opening 80 e of the mounting plate 1 and the locking tongue piece 80 g of the mounting plate 1 inserted into the insertion hole 10 f of the LED lamp body 2, The tongue piece 80g engages with the claw portion of the rotation locking piece 10g of the LED lamp body 2. Thereby, the LED lamp main body 2 is attached to the attachment plate 1.
