Description

  The present invention relates to an LED dimming / lighting device for dimming an LED.

  Conventionally, an LED dimming / lighting device that performs dimming of an LED (Light Emitting Diode) by duty control is used (see Patent Document 1). The configuration of the conventional LED dimming / lighting device disclosed in Patent Document 1 will be described with reference to FIG.

FIG. 1 is a circuit diagram showing a configuration of an LED dimming / lighting device 9 disclosed in Patent Document 1. As shown in FIG. The LED dimming / lighting device 9 includes a diode bridge circuit DB90, a transformer T, a switching element 93 for chopper control, a DC power supply circuit DC90 including a diode and a smoothing capacitor C90, a white LED array 91, a light bulb color LED array 96, , A switching element 92 for DUTY control, and a control circuit 94 for controlling the switching elements 92 and 93.
Regarding the number of turns of the transformer T, the secondary side is set to be smaller than the primary side so that the DC power supply circuit DC90 serves as a down converter.

  The DC power supply circuit DC90 performs full-wave rectification on the output of the commercial AC power supply AC with the diode bridge circuit DB90, and chops it with the switching element 93 on the primary side of the transformer T. Further, the DC power supply circuit DC90 rectifies the output of the transformer T with a diode, and then smoothes it with a capacitor C90. As a result, a DC current output from the DC power supply circuit DC90 flows through the white LED array 91 and the light bulb color LED array 96, and the plurality of LEDs emit light.

Here, in the white LED array 91, current flows only during the on period of the switching element 92, and the brightness is determined by the average current per time.
The control circuit 94 receives a dimming signal indicating the dimming degree from the remote controller 95. The control circuit 94 performs duty control so as to reduce the on-duty of the switching element 92 as the dimming level becomes dark, and reduces the current flowing through the white LED array 91. Conversely, the control circuit 94 performs duty control so as to increase the on-duty of the switching element 92 as the dimming level becomes brighter, and increases the current flowing through the white LED array 91.

  As described above, the LED dimming / lighting device 9 disclosed in Patent Document 1 performs dimming of the white LED array 91 by duty control.

That is, in order to perform the above-described duty control, an expensive LSI and a power control transistor are required.
For this reason, the conventional LED dimming / lighting device including the LED dimming / lighting device 9 of Patent Document 1 has a problem in that the product cost increases when dimming the LED.

In this configuration, the alternating current output from the alternating current power supply is input to the first rectifier circuit. The first rectifier circuit rectifies the output of the AC power supply to generate a DC drive current, and inputs it to the first conductive portion of the switch unit. The drive current flows to the output terminal connected to the first conductive portion, and is supplied to the LED connected to the output terminal. As a result, the LED emits light.
In this configuration, the user operates the operation member to displace the first conductive portion. As a result, the number of output terminals connected to the first conductive portion varies depending on the position of the displaced first conductive portion. Therefore, the user can change the number of LEDs that emit light by supplying a drive current by operating the operation member.

In FIG. 4 and FIG. 9 to be described later, a gap is shown between the second conductive portion 12B and the output terminal 18, but there is actually no gap, and both are in contact with each other. Similarly, the gap between the first conductive portion 11B and the output terminal 18 contacts when the first conductive portion 11B rotates as shown in FIGS.
The control unit 50 and the switch unit 10 are connected to each other by a control line (not shown). When the switch unit 10 is turned off, an electrical signal is input to the control unit 50 via the control line, and the control unit 50 is turned on.

  Each of the plurality of DC power sources DC <b> 1 to DC <b> 10 is connected in parallel to each output terminal 18 of the switch unit 10.

The other DC power supplies DC2 to DC10 are also composed of the same rectifier circuit DB1 and smoothing capacitor C1 as the DC power supply DC1.

  Each of the light emitting diodes L1 to L10 is connected to each of the plurality of DC power supplies DC1 to DC10 on a one-to-one basis.

  In the above configuration, the alternating current output from the alternating current power supply AC is input to the first conductive portion 11A of the switch unit 10. The alternating current flows to the output terminal 18 connected to the first conductive portion 11B, and is input to the direct current power source DC connected to the output terminal 18. The DC power supply DC rectifies and smoothes the output of the switch unit 10 to generate a DC drive current, and supplies the drive current to the light emitting diode L connected to the DC power supply DC.

  FIG. 6 is a circuit diagram of the LED dimming / lighting device 1 according to the first embodiment of the present invention when the knob 16 is rotated 45 degrees to light half of the LEDs, and FIG. It is a circuit diagram when turning the knob 16 90 degrees in the light lighting device 1 to light all the LEDs.

  In this embodiment, the user rotates the knob 16 shown in FIG. 2 (for example, 45 degrees or 90 degrees) to displace the first conductive portions 11A and 11B. Accordingly, the number of output terminals 18 connected to the first conductive portion 11B changes according to the positions of the displaced first conductive portions 11A and 11B (see FIGS. 4, 6, and 7). For this reason, the user can change the number of the light emitting diodes L1 to L10 that emit light by supplying a drive current by operating the knob 16. That is, the user can perform light control of the light emitting diodes L1 to L10 by operating the knob 16.

  Therefore, the LED dimming / lighting device 1 can perform dimming of the light emitting diodes L1 to L10 without using an expensive LSI or a power control transistor. Therefore, according to this embodiment, the LED dimming / lighting device 1 capable of dimming the light emitting diodes L1 to L10 can be provided which can be manufactured at low cost.

  Next, the user operates the knob 16 to displace the first conductive portions 11A and 11B, and all the output terminals 18 of the switch unit 10 are connected to the second conductive portion 12B and are not connected to the first conductive portion 11B. The scene (refer FIG. 4) made into the OFF state is demonstrated.

FIG. 8 is a waveform diagram showing operations of the human body sensor 60 and the controller 50 shown in FIG.
The control unit 50 receives an alternating current output from the alternating-current power supply AC (see FIG. 4). As shown in FIG. 8, the control unit 50 blocks the passage of the alternating current to the second conductive portion 12 </ b> A of the switch unit 10 when the human body sensor 60 is not sensing a human body. For this reason, in the switch-off state, all the light emitting diodes L1 to L10 are turned off.

  However, as shown in FIG. 8, the control unit 50 inputs an alternating current to the second conductive portion 12 </ b> A of the switch unit 10 when the human body sensor 60 senses a human body. Then, the control unit 50 continues the input of the alternating current to the second conductive portion 12A until a predetermined time (60 seconds in this embodiment) elapses from when the human body sensor 60 last senses the human body. For this reason, when a person is detected by the human body sensor 60, an alternating current is input to the second conductive portion 12A and transmitted to all the output terminals 18 connected to the second conductive portion 12B. As a result, the drive current generated by each DC power source DC1 to DC10 connected to each output terminal 18 is supplied to each light emitting diode L1 to L10, and all the light emitting diodes L1 to L10 emit light.

  Therefore, according to this LED dimming / lighting device 1, even when a person (such as an intruder) approaches the device body in the switch-off state, all the light emitting diodes L1 to L10 can be turned on.

  Further, after the predetermined time has elapsed, the control unit 50 again blocks the passage of the alternating current to the second conductive portion 12A (see FIG. 8). Therefore, all the light emitting diodes L1 to L10 return to the off state again. Therefore, according to this LED dimming / lighting device 1, since all the light emitting diodes L1 to L10 are automatically turned off, power consumption can be reduced.

<< Second Embodiment >>
FIG. 9 is a circuit diagram of the LED dimming / lighting device 2 according to the second embodiment of the present invention. The LED dimming / lighting device 2 is different from the LED dimming / lighting device 1 shown in FIG. 4 in that DC power sources DC21 and DC22 are provided instead of the DC power sources DC1 to DC10. Each of the DC power supplies DC21 and DC22 includes a rectifier circuit and a smoothing capacitor, like the DC power supply DC1.

  In this configuration, an alternating current output from the AC power supply AC is input to the DC power supply DC21. The direct current power source DC21 rectifies and smoothes the output of the alternating current power source AC to generate a direct current drive current, which is input to the first conductive portion 11A of the switch unit 10. The drive current flows to the output terminal 18 connected to the first conductive portion 11B, and the drive current is supplied to the light emitting diode L connected to the output terminal 18 via a resistor. Thereby, the light emitting diode L emits light.

  Also in this embodiment, the user rotates the knob 16 shown in FIG. 2 (for example, 45 degrees or 90 degrees) to displace the first conductive portions 11A and 11B, so that the displaced first conductive portions 11A and 11B Depending on the position, the number of output terminals 18 connected to the first conductive portion 11B varies (see FIGS. 9, 6, and 7). For this reason, the user can change the number of the light emitting diodes L1 to L10 that emit light by supplying a drive current by operating the knob 16. That is, the user can perform light control of the light emitting diodes L1 to L10 by operating the knob 16.

  Therefore, also in the LED dimming / lighting device 2 of this embodiment, the light-emitting diodes L1 to L10 can be dimmed without using an expensive LSI or a power control transistor. Therefore, also in this embodiment, it is possible to provide the LED dimming / lighting device 2 capable of dimming the light emitting diodes L1 to L10, which can be manufactured at low cost.

  Next, the user operates the knob 16 to displace the first conductive portions 11A and 11B, and all the output terminals 18 of the switch unit 10 are connected to the second conductive portion 12B and are not connected to the first conductive portion 11B. The scene (refer FIG. 9) made into the OFF state is demonstrated.

  The controller 50 receives an alternating current output from the alternating current power supply AC. As shown in FIG. 8, the control unit 50 blocks the passage of alternating current to the direct-current power source DC22 when the human body sensor 60 is not sensing a human body. For this reason, in the switch-off state, all the light emitting diodes L1 to L10 are turned off.

  However, as shown in FIG. 8, the controller 50 inputs an alternating current to the direct current power source DC22 when the human body sensor 60 senses a human body. Then, the control unit 50 continues the input of the alternating current to the DC power source DC22 until a predetermined time (60 seconds in this embodiment) elapses from when the human body sensor 60 senses the human body last. For this reason, when a person is detected by the human body sensor 60, a direct current driving current generated by the direct current power source DC22 is input to the second conductive portion 12A and transmitted to all the output terminals 18 connected to the second conductive portion 12B. Is done. Thereby, a drive current is supplied to each light emitting diode L1 to L10 connected to each output terminal 18, and all the light emitting diodes L1 to L10 emit light.

  Therefore, according to the LED dimming / lighting device 2, even when a person (such as an intruder) approaches the device body in the switch-off state, all the light emitting diodes L1 to L10 can be turned on.

  Further, after the predetermined time has elapsed, the control unit 50 again blocks the passage of the alternating current to the direct current power source DC22 (see FIG. 8). Therefore, all the light emitting diodes L1 to L10 return to the off state again. Therefore, also in this LED dimming / lighting device 2, since all the light emitting diodes L1 to L10 are automatically turned off, the power consumption can be reduced.

<< Other embodiments >>
In the above embodiment, ten LEDs are provided, but any number of LEDs may be provided in the implementation. For example, when 100 LEDs are provided, the user can freely change the dimming degree in the range of 0% to 100% by changing the number of LEDs to be turned on between 0 and 100. However, in the case of the LED dimming / lighting device 1 according to the first embodiment, it is necessary to provide a DC power supply corresponding to the number of LEDs.

  Further, the LED arrangement pattern is not limited to the arrangement pattern shown in FIG. 3, and other arrangement patterns may be adopted. However, since the light from the LED is linear, as shown in FIG. 3, it is preferable to arrange the LED so that the LED that is extinguished when dimming is not noticeable as much as possible.

  Further, in the above embodiment, the operation unit 10 is attached to the main body 102 as shown in FIGS. 2 and 3, but in implementation, the switch unit 10 is attached to the wall of the room R as shown in FIG. 10. It doesn't matter. In this case, the user adjusts the brightness of the room R by adjusting the light-emitting diodes L <b> 1 to L <b> 10 by rotating the knob 16 attached to the wall without removing the illumination globe 100 from the main body 102.
