The light source 13 outputs a first light emitting diode unit 131 that outputs a light source having a first illumination color temperature and a light source having a second illumination color temperature. In the first and second preferred embodiments, the light source having the first illumination color temperature is cold white light having a color temperature value of 6000K, and the light source having the second illumination color temperature is a color temperature value. It is 3000K warm white light. In addition, the changeover switch 11 is connected to the power supply end 2 and the driving device 12 is electrically connected between the changeover switch 11 and the light source 13, so that when the changeover switch 11 is turned on (turn on), the power supply end 2 Supplies power to the driving device 12, drives the first light emitting diode unit and / or the second light emitting diode unit to emit light, and when the changeover switch 11 is turned off, the power supply terminal 2 is connected to the driving device 12. No power is supplied, and therefore the first light emitting diode unit and the second light emitting diode unit are turned off.

  The drive device 12 includes a count control unit 121, a pulse width modulation control unit 122, a drive circuit 123, a bridge rectifier 124, and a transformer unit 125. When the changeover switch 11 is in an on state, the bridge rectifier 124 is connected to an AC from the power supply terminal 2. The current is converted into a direct current and supplied to each member of the driving device 12. In addition, the driving device 12 transmits a first operation signal corresponding to the number of times the changeover switch 11 is turned on and transmits the first operation signal to the first light emitting diode unit 131 and / or transmits a second operation signal and outputs the second light emitting diode unit 132. And the first light emitting diode unit 131 generates a first illumination luminance having a first illumination color temperature in response to the first actuation signal, and / or the second light emitting diode unit 132 in response to the second actuation signal. A second illumination brightness having a second illumination color temperature is generated.

And driving the first light emitting diode unit 131 to drive the first light emitting diode unit 131 to generate the first illumination luminance and / or driving the second light emitting diode unit 132 to generate the second illumination luminance.

  In addition, the control member 1231 is a constant voltage and constant current controller. In the present invention, the control member 1231 includes a control member 1231, resistors R4 to R6, and photocoupler members 1222 and 1232. The output of the driving device 12 is set to a constant current with a constant voltage so that the output of the driving device 12 does not become an overvoltage overcurrent.

  Next, the counting control unit 121 includes a capacitor C7 that supplies time-long power to the flip-flop 1211 when the changeover switch 11 is in an off state, and maintains the constant normal operation time in the flip-flop 1211. Is determined by the standard of the capacitor C7, that is, if the change-over switch 11 is off, the flip-flop 1211 loses power and cannot continue counting, and the change-over switch 11 is turned on again. Then, the number of ON times of the changeover switch 11 is recalculated.

  FIG. 4 is a schematic diagram showing how the preferred operation of the circuit shown in FIG. 2 is realized. In the following, a case where the pulse width modulation control unit 122 maintains the output of a pulse width modulation signal with a duty cycle of 100% after the changeover switch 11 is turned on will be described as an example. Duty cycle) is not limited to this.

  When the changeover switch 11 is turned on for the first time, the first pin Q1 of the flip-flop 1211 outputs a first operation signal to the first light emitting diode unit 131, and the first light emitting diode unit 131 is driven at a work rate of 100% and is illuminated. 1, the first illumination luminance having the first illumination color temperature is generated. When the changeover switch 11 is turned off and turned on for the second time within the time length (that is, when the time interval Td between two pulses when the second on / off operation is performed is shorter than the time length), the flip-flop The second pin Q2 of the group 1211 outputs a second operation signal to the second light-emitting diode unit 132, and the second light-emitting diode unit 132 is driven at 100% power and has a second illumination color temperature in the lighting device 1. Generate illumination brightness.

  When the changeover switch 11 is turned off again and turned on for the third time in the time length, the first pin Q1 of the flip-flop 1211 outputs a first operation signal to the first light emitting diode unit 131, and at the same time, The bi-pin Q2 outputs a second operation signal to the second light emitting diode unit 132, whereby the first light emitting diode 131 and the second light emitting diode unit 132 are simultaneously driven with 100% power (ie, the first light emitting diode). 131 and the second light emitting diode unit 132 are each driven at a work rate of 50%), and the third illumination color temperature generated by mixing the first illumination color temperature and the second illumination color temperature described above with the illumination device 1. Generate three illumination brightness. Here, since the first light-emitting diode 131 and the second light-emitting diode unit 132 of the preferred first embodiment are distributed on average, the color temperature value of the light source of the third illumination color temperature is 4500K daylight white light.

  Incidentally, except for the situation described above, the first light emitting diode unit 131 is driven alone at 100% power, or the second light emitting diode unit 132 is driven alone at 100% power, or the first When the light emitting diode 131 and the second light emitting diode unit 132 are simultaneously driven at 100% power, the first illumination brightness, the second illumination brightness, and the third illumination brightness all have the same illumination brightness. However, only the illumination color temperature can be adjusted, and the illumination brightness cannot be selected, and there is room for improvement in view of user convenience as the illumination device. Therefore, in the following, a preferred second embodiment of the illumination device according to the present invention will be described. Will be further described. This allows the user to select not only the illumination color temperature but also the illumination brightness.

  In the preferred second embodiment, the counting control unit 121 includes a pyrome microcontroller 1212 having a trigger pin Pin, a first P1, a second pin P2 and an output pin Pout, and each time the change-over switch 11 is turned on once. The trigger pin Pin of the microcontroller 1212 is triggered once every time, thereby calculating the number of times the change-over switch 11 is turned on. The microcontroller 1212 outputs the first operation signal to the first pin P1 alone based on the number of times the trigger pin Pin is triggered, or outputs the second operation signal to the second pin P2 alone, or the first The first operation signal and the second operation signal are simultaneously output to the pin P1 and the second pin P2, respectively. In addition, the microcontroller 1212 outputs a dimming signal to the pulse width modulation control unit 122 corresponding to the number of times the trigger pin Pin is triggered, and then the pulse width modulation control unit 122 sends the corresponding drive signal to the control member 1231. , Output to the drive circuit 123 composed of the capacitor C5 and the plurality of resistors R4 to R6, drive the drive circuit 123 to drive the first light emitting diode unit 131, and / or generate the first illumination luminance. The light emitting diode unit 132 is driven to generate the second illumination luminance.

  In addition, in the second preferred embodiment, the functions of the control member 1231 of the drive circuit and the capacitor C7 of the counting control unit 121 are the same as those of the preferred first embodiment, and further details are omitted here.

  FIG. 5 is a schematic diagram of how the preferred operation of the circuit shown in FIG. 3 is realized. When the change-over switch 11 is turned on for the first time, the trigger pin Pin of the microcontroller 1212 receives the first trigger and causes the first pin P1 of the microcontroller 1212 to output the first operation signal to the first light emitting diode unit 131, and The output pin Pout of the controller 1212 correspondingly outputs the first dimming signal to the pulse width modulation control unit 122, and then the pulse width modulation control unit 122 sends the drive signal to the drive circuit 123 according to the first dimming signal. The driving signal at this time is a pulse width modulation signal having a duty cycle of 100%. As a result, the first light emitting diode unit 131 is driven at a work rate of 100%, and the lighting device 1 generates the first illumination luminance having the first illumination color temperature.

  When the change-over switch 11 is turned off and turned on for the second time within the time length (that is, when the time interval Td between two pulses when the second on / off operation is performed is shorter than the time length), the micro switch The number of times the trigger pin Pin of the controller 1212 is triggered is two times, the second pin P2 of the microcontroller 1212 outputs a second operation signal to the second light emitting diode unit 132, and the output pin Pout of the microcontroller 1212 is Correspondingly, the second dimming signal is output to the pulse width modulation control unit 122, and then the pulse width modulation control unit 122 outputs the driving signal to the driving circuit 123 in accordance with the second dimming signal, and the driving at this time The signal is a pulse width modulation signal with a duty cycle of 75%. Accordingly, the second light emitting diode unit is driven at a work rate of 75%, and the lighting device 1 generates the second illumination luminance having the second illumination color temperature.

  When the changeover switch 11 is turned off again and turned on for the third time in the time length, the trigger pin Pin of the microcontroller 1212 is triggered three times, and the first pin P1 of the microcontroller 1212 is first activated. The signal is output to the first light emitting diode unit 131, and at the same time, the second pin P2 outputs the second operation signal to the second light emitting diode unit 132, and the output pin Pout correspondingly applies pulse width modulation to the third dimming signal. Then, the pulse width modulation control unit 122 outputs a drive signal to the drive circuit 123 according to the third dimming signal, and the drive signal at this time is a pulse with a duty cycle of 60%. It becomes a width modulation signal. As a result, the first light emitting diode unit and the second light emitting diode unit are simultaneously driven with a power of 60% (that is, the first light emitting diode unit and the second light emitting diode unit are each driven with a power of 30%), The illumination device 1 is caused to generate a third illumination brightness having a third illumination color temperature. Here, the first light emitting diode unit and the second light emitting diode unit of the preferred second embodiment are averagely distributed, and the light source of the third illumination color temperature is daylight white light having a color temperature value of 4500K.

  When the changeover switch is turned off again and turned on for the fourth time in the time length, the trigger pin Pin of the microcontroller 1212 is triggered four times, and the first operation signal is sent to the first pin P1 of the microcontroller 1212. Are output to the first light emitting diode unit 131, and the output pin Pout of the microcontroller 1212 correspondingly outputs the fourth dimming signal to the pulse width modulation control unit 122. Subsequently, the pulse width modulation control unit 122 A drive signal is output to the drive circuit 123 according to the fourth dimming signal, and the drive signal at this time becomes a pulse width modulation signal with a duty cycle of 80%. As a result, the first light emitting diode unit 131 is driven at a power of 80%, and causes the lighting device 1 to generate the fourth lighting luminance having the first lighting color temperature.

  Incidentally, the first illumination brightness to the fourth illumination brightness are directly proportional to the driving power supplied by the driving device 12, and as described above, the first illumination brightness to the fourth illumination brightness are all different. It is. Naturally, the above description is merely an embodiment, that is, by setting the firmware in the pyrome microcontroller 121 according to different circumstances before the manufacture and shipment of the lighting device 1, the changeover switch 11 of the drive device 12 is set. The power for driving to be supplied to the first light emitting diode unit and / or the second light emitting diode unit can be set according to the number of times of turning on.

  The light emitting source 13 of the lighting device 1 of the present invention is not limited to the one including the first light emitting diode unit 131 that outputs the light source having the first illumination color temperature and the second light emitting diode unit 132 that outputs the light source having the second illumination color temperature. In addition, by including a light emitting diode unit that outputs a light source having another illumination color temperature, it is also within the scope of the present invention that the illumination device further generates a variety of illumination color temperatures and illumination brightness to expand the user's choice. This can be easily realized by the driving principle and concept described above.

  In addition, the lighting device 1 of the present invention is applied to room lighting, which is home lighting, commercial lighting, table lamps or bed lights, but is not limited thereto. Hereinafter, how the user operates the lighting device of the present invention will be described. 6 and 7, FIG. 6 is a schematic view of an operation interface of a preferred embodiment of a lighting device with adjustable color temperature according to the present invention, and FIG. 7 is an application of the operation interface shown in FIG. 6 to a table lamp. It is the schematic in the case. According to FIG. 6, the operation interface 14 has a switch part 141, and the switch part 141 may be the changeover switch 11 originally installed on the wall of the room, or the changeover switch originally installed on the table lamp 3 as shown in FIG. But you can. For this reason, the user turns on the changeover switch 11 by pressing the switch unit 141, and can select an appropriate illumination color temperature and illumination luminance by changing the number of times the switch unit 141 is pressed according to the use environment.

  Incidentally, the first light emitting diode unit 131 includes a light emitting diode that is a light source that outputs a plurality of first illumination color temperatures, and the second light emitting diode unit 132 includes a light emitting diode that is a light source that outputs a plurality of second illumination color temperatures. Including. Here, if light emitting diodes that output light sources having the same illumination color temperature are excessively concentrated and arranged, the light mixing effect of the light source of the first illumination color temperature and the light source of the second illumination color temperature is reduced. Then, we will submit two types of installation rules for the average distribution array of light emitting diodes with different illumination color temperatures, effectively improving the quality of the light source of the third illumination color temperature.

  First, one of the installation principles of an average distribution array of light emitting diodes having different illumination color temperatures will be described. All the light-emitting diodes of the light-emitting source 13 of the illumination device 1 are symmetrically arranged with respect to each other, are positioned on both sides of the symmetry axis, and any two light-emitting diodes corresponding to each other along the symmetry axis are provided. The output light source has the same illumination color temperature. In addition, the light emitting diode array groups located on either side of the symmetry axis are classified into at least two light emitting diode array subgroups, and the light emitting diodes in each light emitting diode array subgroup are linearly arranged or non-linear. Presents an array of shapes. What is important is that the illumination color temperature of the light source output from any two adjacent light emitting diodes in each light emitting diode array subgroup is different.

  More preferably, the illumination color temperature of the light source output by any two adjacent light emitting diodes arranged around (outermost circumference) of all the light emitting diodes is also different.

  FIG. 8 is a schematic view of an arrangement of a first preferred embodiment of a light emitting diode as a light emitting source. A light emitting diode 1311 indicated by W in the figure outputs a light source having a first illumination color temperature, and C in the figure. The light emitting diode 1312 indicated by indicates that a light source having the second illumination color temperature is output. All of the light emitting diodes 1311 and the light emitting diodes 1312 are symmetrically arranged with respect to the symmetry axis 133, and are positioned on both sides of the symmetry axis 133, and either two light emitting diodes corresponding to each other along the symmetry axis 133 output. The light source has the same illumination color temperature (two light emitting diodes marked with diagonal lines in the diagram). In addition, the light emitting diode array groups located on either side of the symmetry axis 133 include three light emitting diode array subgroups G1, G2, and G3 (light emitting diodes that pass through the same dotted line are the same light emitting diode array). All the light emitting diodes 1311 and 1312 in each light emitting diode array subgroup are arranged in an S shape or an inverted S shape, and any two of them are adjacent to each other. The illumination color temperatures of the light sources output from the light emitting diodes are all different.

  In addition, in order to further uniformly distribute and arrange the light emitting diodes 1311 and the light emitting diodes 1312 having different illumination color temperatures, in this embodiment, the periphery of all the light emitting diodes 1311 and the light emitting diodes 1312 (light emitting diodes that pass through the outermost dotted line). Any two adjacent light emitting diodes are made to output light sources having different illumination color temperatures. In the present embodiment, a plurality of light emitting diodes 1311 and light emitting diodes 1312 are provided on the symmetry axis 133, and the illumination color temperature of the light source output from any two adjacent light emitting diodes is also different. Of course, the above description is only one embodiment, and any light emitting diode can be installed on the axis of symmetry.
