Embodiment 1 FIG.
The first embodiment will be described with reference to FIGS.

FIG. 1 is a perspective view showing an external appearance of a lighting fixture 800 in this embodiment.
FIG. 2 is a side view cutaway view showing the structure of the lighting fixture 800 in this embodiment.

The lighting fixture 800 is downlight illumination that is used by being embedded in a ceiling or the like. The lighting fixture 800 includes a fixture body 810, a frame 820, a mounting spring 830, a power supply terminal block 840, the LED module 100, and the lighting device 200.
The fixture main body 810 (case) is the main body of the lighting fixture 800 and incorporates the lighting device 200.
The frame 820 is a portion exposed downward from the ceiling or the like, and hides a hole provided in the ceiling or the like for embedding the lighting fixture 800.
The attachment spring 830 is a leaf spring or the like, and prevents it from falling from a hole in which the lighting fixture 800 is attached.
The power supply terminal block 840 is connected to an AC power supply such as a commercial power supply, inputs power from the AC power supply, and supplies the power to the lighting device 200.
The lighting device 200 generates a voltage for lighting the LED 130 built in the LED module 100 by the electric power input from the power terminal block 840.

The LED module 100 (light source module) includes a translucent cover 110, a substrate 120, an LED 130, and a sensor 140.
The translucent cover 110 is a cover that covers the substrate 120 and the LEDs 130 in the LED module 100. The translucent cover 110 is transparent or opaque and translucent, and allows light emitted from the LED 130 to pass through. The translucent cover 110 is made of, for example, acrylic, polycarbonate, nylon resin, or the like.
The substrate 120 is a disc-shaped printed wiring board made of aluminum, glass epoxy, paper phenol, or the like, and a circuit for applying the voltage generated by the lighting device 200 to the LED 130 is mounted thereon.
The LED 130 (light source) is a light emitting diode mounted on the substrate 120, and emits light when a voltage generated by the lighting device 200 is applied.
The sensor 140 is, for example, a pyroelectric sensor, an illuminance sensor, a radio wave sensor, or the like, and detects the surrounding state. The detection result detected by the sensor 140 is input to the lighting device 200 as a signal. The lighting device 200 includes a control unit (not shown). The control unit determines the lighting state of the LED 130 based on the detection result detected by the sensor 140, and based on the determined lighting state, the lighting device 200. Turns on the sensor 140.
For example, when the sensor 140 is a pyroelectric sensor (human sensor), the sensor 140 detects whether or not there is a person around, and the lighting device 200 is based on the determination of the control unit when there is a person around. The LED 130 is turned on, and the LED 130 is turned off when there is no person around. Alternatively, when the sensor 140 is an illuminance sensor, the sensor 140 detects ambient brightness, and the lighting device 200 turns on the LED 130 when the surrounding is dark, and turns off the LED 130 when the surrounding is bright.

FIG. 3 is an exploded front view showing the LED module 100 in this embodiment.
The translucent cover 110 has a hollow cylindrical shape without one bottom surface, and includes a bottom surface portion 111, an opening portion 112, a side surface portion 113, and a claw portion 114.
The bottom surface portion 111 is a disk-shaped portion corresponding to the bottom surface of the translucent cover 110 and has an opening 112 at the center.
The opening 112 is a circular through hole for letting the sensor 140 out of the translucent cover 110.
The side surface portion 113 is a cylindrical plate-like portion corresponding to the side surface of the translucent cover 110, and has a claw portion 114 on the inner side.
The nail | claw part 114 is located in the upper end (end on the opposite side to the bottom face part 111) of the side part 113, and when the LED module 100 is assembled, it catches on the board | substrate 120 and latches the translucent cover 110 and the board | substrate 120. To do.

The substrate 120 has a disk shape, and a sensor 140 and four LEDs 130 are mounted on one surface. In addition, the board | substrate 120 may not be disk shape, for example, square shape or a rectangular shape may be sufficient, and another shape may be sufficient as it.
The sensor 140 is located substantially at the center (predetermined center position) of the substrate 120, and includes a light receiving part 141, a collar part 142, and a claw part 143. The light receiving unit 141 is a part that receives infrared rays, visible rays, radio waves, and the like. The collar 142 closes the gap between the translucent cover 110 and the sensor 140 and prevents light emitted from the LED 130 from leaking directly from the gap. In addition, when the translucent cover 110 is colorless and transparent, the collar part 142 may not be provided. The claw portion 143 is a claw for fixing the sensor 140 to the substrate 120 through a hole provided in the substrate 120.
The four LEDs 130 are light-emitting diodes of a surface-mount package, and are arranged at a position approximately equidistant (r ₃ ) from the center of the substrate 120. Further, the four LEDs 130 are arranged at approximately equal intervals at positions spaced apart from each other by about 90 degrees from the center of the substrate 120. That is, the four LEDs 130 are generally positioned on the circumference of the radius r ₃ centered on the center of the substrate 120 and are arranged on the substrate 120 so as to draw a substantially circle.

According to the LED module 100 in this embodiment, since the plurality of LEDs 130 (light sources) are arranged at substantially equal intervals from the predetermined center position, light can be evenly distributed by 360 degrees. it can. Since the sensor 140 (human sensor) is disposed at a position surrounded by the LEDs 130, the light emitted from the LEDs 130 can be evenly distributed 360 degrees without being blocked by the sensor 140. Since the sensor 140 (human sensor) is disposed at a predetermined center position, the irradiation range of the light emitted from the LED 130 and the detection range of the sensor 140 can be matched. Since the LED 130 is used as a light source, the power consumption can be suppressed and the lifetime is increased (for example, 40,000 hours). Since the translucent cover 110 that transmits light covers the plurality of LEDs 130, the number of components of the LED module 100 can be reduced. Since the sensor 140 and the LED 130 are integrated, the structure becomes simple and the lighting fixture 800 can be made compact.
Moreover, according to the lighting fixture 800 in this embodiment, the control unit determines the lighting state of the sensor 140 based on the detection result detected by the sensor 140, and the lighting device 200 includes the LED 130 based on the determined lighting state. Since it is turned on, it is possible to reduce unnecessary lighting and save energy.

FIG. 4 is a view showing a modification of the LED module 100 in this embodiment.
The number of LEDs 130 is not limited to four, but may be two, three, or more.
Also in this case, the plurality of LEDs 130 are arranged at substantially equal intervals at positions approximately equidistant from the center of the substrate 120. For example, if there are two LEDs 130, the LEDs 130 are arranged at positions that are separated from the center of the substrate 120 by about 180 degrees. If there are three LEDs 130, the LEDs 130 are arranged at positions that are separated from the center of the substrate 120 by about 120 degrees. In the case of eight LEDs 130, the LEDs 130 are arranged at positions separated by about 45 degrees from the center of the substrate 120. Thereby, light can be distributed evenly by 360 degrees.

Embodiment 2. FIG.
Embodiment 2 will be described with reference to FIG.
In addition, about the part which is common in the lighting fixture 800 demonstrated in Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 5 is a perspective view and an exploded front view showing the LED module 100 according to this embodiment.
The translucent cover 110 is made of nylon resin or the like, and does not have the opening 112 in the bottom surface portion 111 and covers the plurality of LEDs 130 and the entire sensor 140.
The sensor 140 is lower in height than the sensor 140 of the first embodiment, is housed in the translucent cover 110, and has no collar 142.

As described above, by using the sensor 140 having a low height, it is not necessary to provide the opening 112 in the translucent cover 110 and there is no possibility of light leakage from the opening 112. There is no need to provide the portion 142. For this reason, the manufacturing cost of the LED module 100 can be reduced. Since the sensor 140 is covered with the translucent cover 110, the sensor 140 can be used as a single sensor element instead of being packaged, and the manufacturing cost of the LED module 100 can be reduced.
When the translucent cover 110 is cloudy and translucent, infrared light, visible light, and radio waves received by the sensor 140 are diffused by the translucent cover 110. For this reason, the detection range of the sensor 140 can be widened.
Moreover, if the center of the bottom surface portion 111 of the translucent cover 110 is processed into a lens shape, the detection range of the sensor 140 can be adjusted.

  In the case where the sensor 140 is a sensor that detects infrared rays, such as a pyroelectric sensor, and the translucent cover 110 is formed of a material that reflects or absorbs infrared rays, The configuration in which the light receiving unit 141 is brought out of the translucent cover 110 as in the first embodiment is preferable.

Embodiment 3 FIG.
Embodiment 3 will be described with reference to FIGS. 6 and 7. FIG.
In addition, about the part which is common in the lighting fixture 800 demonstrated in Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 6 is a perspective view and an exploded front view showing the LED module 100 in this embodiment.
The translucent cover 110 has a partition wall 115. The partition wall 115 has a cylindrical side surface surrounding the periphery of the opening 112 and has an upper end reaching the surface of the substrate 120, and closes a gap between the sensor 140 and the translucent cover 110.
Thereby, even if the sensor 140 does not have the collar part 142, it can prevent that the light which LED130 emitted leaks directly from the opening part 112. FIG.

FIG. 7 is a perspective view and an exploded front view showing a modification of the LED module 100 in this embodiment.
The sensor 140 does not need to protrude from the translucent cover 110, and may be flush with the bottom surface portion 111 or recessed from the bottom surface portion 111.

As described above, the partition 115 surrounds the periphery of the opening 112 in place of the collar 142, so that light emitted from the LED 130 can be prevented from leaking from the opening 112.
In the case where the sensor 140 is a sensor that receives visible light such as an illuminance sensor, the partition 115 is blocked from light such as resin colored in black in order to prevent the sensor 140 from reacting to the light emitted from the LED 130. It is preferable that it is made of a material to be used.

Embodiment 4 FIG.
The fourth embodiment will be described with reference to FIG.
In addition, about the part which is common in the lighting fixture 800 demonstrated in Embodiment 3, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 8 is a perspective view and an exploded front view showing the LED module 100 in this embodiment.
The LED module 100 further includes a sensor 150. The sensor 150 is a sensor different in type from the sensor 140. For example, the sensor 140 is a pyroelectric sensor (human sensor), and the sensor 150 is an illuminance sensor. The sensor 140 and the sensor 150 are disposed in the vicinity of the center of the substrate 120 within a range surrounded by the plurality of LEDs 130.
The translucent cover 110 has two openings 112. The two openings 112 are circular through holes provided at positions and sizes corresponding to the two sensors 140 and 150, respectively. There is a partition 116 around each opening 112. The partition wall 116 has a cylindrical side surface surrounding the opening 112. In this example, unlike the partition wall 115 described in Embodiment 3, the partition wall 116 does not reach the surface of the substrate 120. However, like the partition wall 115 described in Embodiment 3, the partition wall 116 reaches the surface of the substrate 120. There may be.

Taking the case where the sensor 140 is a human sensor and the sensor 150 is an illuminance sensor as an example, how the control unit determines the lighting state of the LED 130 will be described.
A control part determines the lighting state of LED130 based on the detection result which the sensor 140 and the sensor 150 detected.
When the ambient brightness is equal to or greater than a predetermined illuminance (hereinafter referred to as “illuminance threshold value”), when the sensor 150 detects, the control unit determines to turn off the LED 130.
When the sensor 150 detects that the ambient brightness is less than the illuminance threshold, the control unit determines whether to turn on or off the LED 130 based on the detection result of the sensor 140. When the sensor 140 detects that there is a person around, the control unit determines to light the LED 130. When the sensor 140 detects that there is no person around, the control unit calls a predetermined time (hereinafter referred to as “lighting holding time”) since the last time the sensor 140 detected that there was a person around. If it is less than), it is determined that the LED 130 is turned on, and if there is a person in the vicinity, if the elapsed time from the last detection by the sensor 140 is equal to or longer than the lighting holding time, it is determined that the LED 130 is turned off.
The lighting device 200 turns on or off the LED 130 based on the determination by the control unit.

  In this way, by combining a plurality of types of sensors 140 and 150, it is possible to control the lighting and extinguishing of the LED 130 in more detail, thereby reducing unnecessary lighting and suppressing the power consumption of the lighting fixture 800. . Since the sensor 150 (illuminance sensor) is disposed at a position surrounded by the plurality of LEDs 130 (light sources), the light emitted from the LEDs 130 can be evenly distributed 360 degrees without being blocked by the sensor 150.

Embodiment 5 FIG.
The fifth embodiment will be described with reference to FIG. 9 and FIG.
In addition, about the part which is common in the lighting fixture 800 demonstrated in Embodiment 4, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 9 is a perspective view and an exploded front view showing the LED module 100 in this embodiment.
The LED module 100 further includes two adjustment switches 160 and 170. The two adjustment switches 160 and 170 are switches for adjusting the sensitivity of the two sensors 140 and 150, and are arranged in the vicinity of the center of the substrate 120 within the range surrounded by the plurality of LEDs 130.
The translucent cover 110 has four openings 112. The four openings 112 are circular through holes provided at positions and sizes corresponding to the two sensors 140 and 150 and the two adjustment switches 160 and 170, respectively. There is a partition 116 around each opening 112.
The two adjustment switches 160 and 170 protrude from the opening 112 to the outside of the translucent cover 110 and can be rotated by picking them with a finger or using a tool such as a screwdriver.

Taking the control method described in the fourth embodiment as an example, how the control unit determines the lighting state of the LED 130 will be described.
The adjustment switch 160 is, for example, a switch that adjusts the lighting illuminance, and can be switched to three stages of “off”, “bright”, and “dark”. When the adjustment switch 160 is “OFF”, the control unit turns on the LED 130 based on the detection result of the sensor 140 detecting whether or not there is a person, regardless of the ambient brightness detected by the sensor 150. Decide whether to turn off or turn off. When the adjustment switch 160 is “bright”, the control unit selects a larger (brighter) illuminance threshold (50 lux) out of two types of illuminance thresholds (for example, 50 lux and 10 lux), and the adjustment switch 160 In the case of “dark”, the control unit selects a smaller (darker) illuminance threshold value (10 lux) from the two types of illuminance threshold values. Based on the selected illuminance threshold, the control unit determines whether to turn on or off the LED 130 by the control method described in the fourth embodiment.
The adjustment switch 170 is, for example, a switch for adjusting the lighting holding time, and can be switched to three stages of “1 minute”, “3 minutes”, and “continuous”. When the adjustment switch 170 is “1 minute”, the control unit sets the lighting holding time to 1 minute, and when the adjustment switch 170 is “3 minutes”, the control unit sets the lighting holding time to 3 minutes. Based on the set lighting holding time, the control unit determines whether to turn on or off the LED 130 by the control method described in the fourth embodiment. When the adjustment switch 170 is “continuous”, the control unit sets the lighting holding time to infinity, and turns on or off the LED 130 according to the control method described in the fourth embodiment based on the set lighting holding time. Decide what to do. That is, when the ambient brightness detected by the sensor 150 is less than the illuminance threshold value and the sensor 140 detects that there is a person in the surroundings, the control unit determines that the LED 130 is lit, and then the person around the person Even if the sensor 140 detects that there is no light, the LED 130 continues to be lit. The control unit determines that the LED 130 is turned off when the ambient brightness detected by the sensor 150 exceeds the illuminance threshold. Therefore, the LED 130 continues to be lit until the surroundings become bright or the lighting fixture 800 is turned off.

  In this way, by enabling the adjustment switches 160 and 170 to adjust the illuminance threshold and the lighting holding time, it is possible to control the lighting and extinguishing of the LED 130 in more detail. Since the adjustment switches 160 and 170 are disposed at positions surrounded by the plurality of LEDs 130 (light sources), the light emitted from the LEDs 130 can be evenly distributed 360 degrees without being blocked by the adjustment switches 160 and 170. At the same time, since the adjustment switches 160 and 170 are on the light emitting surface side, it is easy to operate and adjustment can be performed easily. Moreover, the lighting fixture 800 can be made compact as a whole.

FIG. 10 is a perspective view and an exploded front view showing a modified example of the LED module 100 in this embodiment.
The adjustment switches 160 and 170 have a low height and are recessed from the bottom surface portion 111. The adjustment switches 160 and 170 can be rotated by inserting a tool such as a screwdriver from the opening 112.
When the lighting fixture 800 is installed on the wall surface, the adjustment switches 160 and 170 are depressed more than the bottom portion 111 in this way in order to prevent erroneous operation by touching the adjustment switches 160 and 170 by mistake. preferable.

Embodiment 6 FIG.
Embodiment 6 will be described with reference to FIGS. 11 and 12. FIG.
In addition, about the part which is common in the lighting fixture 800 demonstrated in Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 11 is a perspective view showing an overview of the lighting fixture 850 in this embodiment.
FIG. 12 is a side view showing how the lighting fixture 850 is used in this embodiment.

The lighting fixture 850 is a bulb-type lighting fixture, and is used by being connected to an existing lighting fixture 300 having a lamp socket 310 for a bulb. The lighting fixture 850 includes a fixture main body 860, an adjustment switch 870, a base portion 880, and the LED module 100.
The fixture main body 860 is a main body of the lighting fixture 850, and incorporates the lighting device 200 (not shown). The instrument body 860 is made of a material having high thermal conductivity such as aluminum. The adjustment switch 870 is a switch for adjusting the sensitivity of the sensors 140, 150, etc., similar to the adjustment switches 160, 170 described in the fifth embodiment, and is located on the side surface of the instrument body 860. The base unit 880 has substantially the same shape as the base of an existing light bulb, and inputs power from an AC power source such as a commercial power source by connecting the existing light bulb to a connectable lamp socket.
The existing lighting fixture 300 for a light bulb includes a lamp socket 310, a reflector 320, a frame 330, a mounting spring 340, and a power terminal block 350. The lamp socket 310 is a socket to which a base of an existing light bulb can be connected, and supplies electric power from an AC power source such as a commercial power source to the connected light bulb (or lighting fixture 850). The reflection plate 320 is a plate having a substantially truncated cone side surface with a mirror surface in order to reflect light emitted from the light bulb connected to the lamp socket 310 and obtain a predetermined light distribution. The frame 330 is a portion exposed downward from the ceiling or the like, and hides a hole provided in the ceiling or the like for embedding the lighting fixture 300. The attachment spring 340 is a leaf spring or the like, and prevents it from falling from the hole in which the luminaire 300 is attached. The power terminal block 350 is connected to an AC power source such as a commercial power source, and receives power from the AC power source and supplies it to the lamp socket 310.

In this way, since the base 880 can be connected to the lamp socket 310 for a light bulb and inputs an AC voltage, the lighting device 850 can be easily attached and turned on without replacing the existing light bulb lighting device 300. can do. Thereby, since the existing lighting fixture 300 can be utilized as it is, waste can be reduced.
Moreover, since the instrument body 860 is made of a material having high thermal conductivity such as aluminum, the heat generated by the LED 130 can be efficiently radiated. In order to further increase the heat dissipation efficiency, an electric heating sheet such as silicon may be sandwiched between the back side of the substrate 120 and the instrument main body 860.
Instead of providing the adjustment switch 870 on the side surface of the instrument main body 860, adjustment switches 160 and 170 may be provided on the light emitting surface as in the fifth embodiment. Then, the operation of the adjustment switches 160 and 170 becomes easy.
On the other hand, in the case where the adjustment switch 870 is provided on the side surface of the fixture body 860, it is necessary to operate the adjustment switch 870 after the lighting fixture 850 is removed from the lamp socket 310 of the lighting fixture 300. The operation is not performed so frequently, and the lighting fixture 850 can be easily attached to and removed from the lamp socket 310. Therefore, the configuration in which the adjustment switch 870 is provided on the side surface of the fixture main body 860 provides a cleaner light emitting surface and is more attractive in design. Excellent and preferred.

Embodiment 7 FIG.
Embodiment 7 will be described with reference to FIGS. 13 and 14. FIG.
In addition, about the part which is common in the lighting fixture 850 demonstrated in Embodiment 6, the same code | symbol is attached | subjected and description is abbreviate | omitted.

FIG. 13 is a front view showing an example of the shape of the translucent cover in this embodiment.
The translucent cover 110 a has a hooking portion 180 on the side surface portion 113. The hooking portion 180 has a substantially triangular prism shape, and the plurality of hooking portions 180 fill the side surface portion 113 without any gap. The height direction of the triangular prism formed by the hook portion 180 is equal to the height direction of the cylinder formed by the translucent cover 110, and the upper end of the hook portion 180 coincides with the upper end of the side surface portion 113. The lower end of the hook portion 180 is above the lower end of the side surface portion 113, and the lower bottom surface of the hook portion 180 has a taper. The hook portion 180 can be hooked with a finger, and the entire lighting fixture 850 can be rotated by putting the finger on the hook portion 180 and turning the hook portion 180, and the lighting fixture 850 is connected to the lamp socket of the lighting fixture 300. The operation of attaching / detaching to / from 310 becomes easy.

The translucent cover 110b is different from the translucent cover 110a in that the hook portion 180 does not completely fill the side surface portion 113 and a gap is opened. Another difference is that the upper end surface of the side surface portion 113 is also tapered.
The translucent cover 110c is different in that the hooking portion 180 is substantially rectangular parallelepiped. Another difference is that the upper end of the hook portion 180 does not coincide with the upper end of the side surface portion 113 and is lower than the upper end of the side surface portion 113.

FIG. 14 is a front view showing a modification of the shape of the translucent cover in this embodiment.
In the translucent cover 110d, the catching portion 180 has a substantially hemispherical shape, and the positions of the plurality of catching portions 180 in the height direction are not the same.
The translucent cover 110e has only four hooks 180, and is 90 degrees apart from each other.
The translucent cover 110 f has a hooking portion 180 on the bottom surface portion 111 instead of the side surface portion 113.

  As described above, the shape, position, number, etc. of the hooking unit 180 may be arbitrary as long as the hooking unit 180 can hook the finger and rotate the entire lighting fixture 850.
