Figure 11 is a block diagram of a lighting system in accordance with a sixth preferred embodiment of the present invention.

In order to explain the present invention more clearly, the following embodiments are described in detail with reference to the drawings. The illuminating system 1 of the first preferred embodiment of the present invention includes a luminaire having an illuminating diode module 10 as an example, an input interface 12, and a phase signal transmitting device 14.

The LED module 10 has a plurality of LEDs for receiving electrical signals to generate illumination to provide illumination. The input interface 12 includes a switch 122 that is a normally open push switch that is in a short circuit state (ie, the first state defined by the present creation) when the user presses.

The phase signal transmitting device 14 includes a phase angle control module 16 and a driving module 18. The phase angle control module 16 is electrically connected to an AC power source S and the switch 122. The phase angle control module 16 is configured to detect the state of the switch 122, and when the switch 122 is pressed and turned on, The phase angle control module 16 changes the waveform of the AC power source S so that the positive half-wave period of the waveform of the AC power source S generates a delayed conduction angle and outputs the signal; and when the switch 122 is not pressed, the switch 122 automatically The reset is in an open state (ie, the second state defined by the present creation), and the phase angle control module 16 does not change the waveform of the AC power source S, that is, the waveform outputted by the phase angle control module 16 does not have the delay conduction. The corner exists. Preferably, the angle of the delayed conduction angle is less than or equal to 90 degrees to reduce the harmonics of the AC power source and reduce the degree of power factor reduction.

Referring to FIG. 2A, in the embodiment, when the switch 122 is pressed (as shown in waveform 1 of FIG. 2A), the phase angle control module 16 changes the communication. The waveform of the power supply S produces a delayed conduction angle at the trailing edge of the positive half-wave period of the output voltage waveform (see waveform 2 of Figure 2A). In practice, it can be designed to produce a retarded conduction angle at the leading edge of the positive half-wave period as shown in Figure 2B. Of course, it is also possible to generate a delayed conduction angle at the negative half wave front or trailing edge, or at the leading or trailing edge of the positive half wave and the negative half wave period, and the recognition as the switch 122 is pressed can also be achieved.

The driving module 18 includes a power conversion circuit 182 and a control unit 184 electrically connected to each other. The power conversion circuit 182 is electrically connected to the phase angle control module 16 and the LED module 10 for receiving the electrical energy output by the phase angle control module 16 and converting the LED into the LED. The power conversion circuit 182 can controllably change the on and off states and brightness of the LED module 10. In the embodiment, the power conversion circuit 182 is designed based on a Pulse Width Modulation (PWM) circuit, and is adjusted to the LED module 10 by pulse width modulation. The clock width of the electrical signal. Of course, in actual implementation, the power conversion circuit 182 can also be designed to adjust the size of the electrical signal or other circuit for adjusting the electrical signal.

The control unit 184 includes a phase angle detecting circuit 184a and a processor 184b. The phase angle detecting circuit 184 is electrically connected to the phase angle control module 16 for detecting whether the waveform of the electric energy output by the phase angle control module 16 has the delayed conduction angle and the angle of detecting the delayed conduction angle. And transmitting the detection result to the processor 184b. The processor 184b has a plurality of control modes including a full illumination mode, a preset illumination mode and a brightness adjustment mode, and controls the electrical signal output by the power conversion circuit 182 in one of the control modes. The light emitting diode module 10 is driven to generate bright light, and the state of the switch 122 is determined by the result of detecting the delayed conduction angle by the phase angle detecting circuit 184a as a basis for switching the control mode. among them: The full-bright illumination mode controls the power conversion circuit 182 to drive the LED module 10 to generate a bright light having a maximum brightness value at a rated power.

The preset illumination mode is configured to control the power conversion circuit 182 to drive the LED module 10 to generate a brightness of a preset brightness value. In this embodiment, the preset brightness value is initially set to be half of the maximum brightness value. The preset brightness value can be updated in the brightness adjustment mode.

The brightness adjustment mode controls the power conversion circuit 182 to drive the light generated by the LED module 10 to change between a first brightness value and a second brightness value until the processor 184b determines the switch 122. When the state changes, the change of the brightness is stopped, and the brightness value of the light generated by the LED module 10 is recorded, and the recorded brightness value is replaced by the preset brightness value of the preset illumination mode, and is driven. The LED module 10 produces bright light having a new preset brightness value. In this embodiment, the first brightness value is a maximum brightness value, and the second brightness value is a minimum brightness value, thereby, in the brightness adjustment mode, the brightness of the LED module 10 is at a maximum brightness The minimum brightness varies. In practice, the processor 184b can also control the power conversion circuit 182 to drive the light generated by the LED module 10 to increase or decrease from a third brightness value between the first and second brightness values. And repeating between a first brightness value and a second brightness value. The third brightness value can be set to one-half of the maximum brightness value, thereby switching to the brightness adjustment mode to first emit light with the centered brightness, thereby preventing the user from feeling eye discomfort due to too much brightness change.

During the period when the switch 122 is pressed, the delay conduction angle exists in every period of the waveform of the electric energy output by the phase angle control module 16, so the processor 184b can calculate according to the number of cycles having the delayed conduction angle. The length of time that the switch 122 is depressed is based on the control mode switching.

In the initial state (when the AC power source S is just turned on) and the switch 122 is not pressed, the phase angle control module 16 does not change the waveform of the AC power source S, and the waveform detected by the phase angle detecting circuit 184a does not have The delay conduction angle, at this time, the processor 184b controls the power conversion circuit 182 to block the power supplied to the LED module 10, so that the LED module 10 is turned off.

After the switch 122 is pressed, the phase angle detecting circuit 184a detects that the waveform of the electric energy output by the phase angle control module 16 has the delayed conduction angle, and the processor 184b determines that the switch 122 is pressed. Time and corresponding control.

When the pressing time is less than a predetermined time (1.2 seconds in this embodiment), the processor 184b switches to the full-light illumination mode to cause the LED module 10 to generate bright light having the maximum brightness value.

After the switch 122 is pressed again, and the pressing time is less than the predetermined time, the processor 184b switches to the preset illumination mode, so that the LED module emits bright light having the preset brightness value.

After the switch 122 is pressed again, and the pressing time is less than the predetermined time, the processor 184b controls the power conversion circuit 182 to block the power supplied to the LED module 10, so that the LED module 10 is In the state of being extinguished.

When the user needs to change the preset brightness value, pressing the switch 122 for more than the predetermined time, the processor 184b switches to the brightness adjustment mode for the user to change the set preset brightness value.

With the above structure, when the lighting system 1 is applied to a building, the switch 122 and the phase angle control module 16 can be installed on the wall surface of the building (ie, installed at a control end), and the The driving module 18 and the LED module 10 are installed on a wall surface or a ceiling of the building (that is, mounted on a load end). Thus, between the phase angle control module 16 and the drive module 18 It is only necessary to connect two wires connected to the AC power source S, in other words, to transmit the waveform corresponding to the state of the switch 122 to the drive module 18 by using the original wiring of the building, and the drive module 18 can judge the switch. The state of 122 is sent to the corresponding LED to control the LED module 10.

The foregoing installation method is only an application example, and is not limited thereto, and the position of each component installation can be adjusted according to actual needs.

In practice, the LED module 10 can include a plurality of first light sources exemplified by the first light emitting diodes and a plurality of second light sources exemplified by the second light emitting diodes, and the plurality of light emitting diodes The light color of the first light emitting diode is different from the light color of the second light emitting diodes. For example, the light colors of the first light-emitting diodes are cold light colors (such as white light, blue light, etc.), and the light colors of the second light-emitting diodes are warm light colors (such as yellow light and red light). Light, etc.).

The power conversion circuit 182 of the driving module 18 can individually control the brightness ratios of the first light emitting diodes and the second light emitting diodes, and the brightness ratio refers to the first and second light colors. The ratio of the brightness value of the brightness generated by the diode to the maximum brightness value or the preset brightness value can be adjusted by using the ratio of the brightness ratios of the first light emitting diode and the second light emitting diode. The color temperature of the bright light generated by the LED module 10.

In the control mode of the processor 184b, the full-brightness illumination mode includes a first brightness ratio information, and the first brightness ratio information is used to record the brightness of the first and second light-emitting diodes when the full-light illumination mode is recorded. proportion. The preset illumination mode includes a second brightness ratio information, and the second brightness ratio information is a brightness ratio of the first and second light emitting diodes when the preset illumination mode is recorded.

The control mode of the processor 184b further includes a chromaticity adjustment mode for adjusting the first ratio information or the second ratio information. When the processor 184b operates in the full-bright illumination mode or the preset illumination mode, the user continuously presses the open switch 122 for another set time (in this embodiment 4 seconds), the operating mode of the processor is switched to the chromaticity adjustment mode. The chromaticity adjustment mode controls the power conversion circuit 182 to drive the LED module 10 to generate bright light, and repeatedly changes the brightness value (ie, the maximum brightness value or the preset brightness value). The brightness ratios of the first light-emitting diodes and the second light-emitting diodes of the LED module 10 are controlled until the processor 184b determines that the state of the switch 122 is changed. And changing the brightness ratio of the second light-emitting diode, and recording the brightness ratio of the first and second light-emitting diodes, and replacing the brightness ratio of the recorded first brightness ratio information of the full-light illumination mode or The first brightness ratio information of the preset illumination mode is replaced, and the first and second light-emitting diodes are driven to generate bright light having a new brightness ratio.

Therefore, the user only needs to press the switch 122 for the length of time to switch the brightness, and adjust the brightness or adjust the chromaticity.

Further preferred embodiments are provided below, again having the same effects as described above.

The lighting system 2 of the second preferred embodiment of the present invention is based on the structure of the first embodiment, and a switch 20 is additionally provided to electrically connect the AC power source S and the phase. Angle control module 16. The switch 20 is configured to turn on and off the light of the LED module 10.

In this embodiment, when the switch 20 is turned on, the processor 184b of the driving module 18 operates in the full-bright illumination mode to make the brightness of the LED module 10 the brightest. Similarly, by pressing the length of the pressing time of the switch 122, the preset illumination mode and the full-light illumination mode can be switched, and the brightness adjustment mode or the chromaticity adjustment can be switched to the same. mode.

The illumination system 3 of the third preferred embodiment of the present invention is based on the structure of the second embodiment described above, except that the input interface 22 of the embodiment includes two switches 222, 224. The switches 222, 224 are electrically connected to the phase angle control module 16. When the switches 222, 224 are pressed to be in a short-circuit state, the phase angle control module 16 generates the delayed conduction angle after the positive half-wave period of the waveform of the AC power source S, and outputs the delay generated by pressing the switches 222, 224. The angles of the conduction angles are different. Thereby, the processor 184b can use the angle of the delayed conduction angle detected by the phase angle detecting circuit 184a to respond to the pressing states of the switches 222, 224 to switch between the control modes.

For example, by short pressing the switch 222 (ie, the pressing time is less than the set time) as the switching between the full-bright illumination mode and the preset illumination mode; long pressing the switch 222 (ie, the pressing time is greater than the set time) , then switch to the brightness adjustment mode.

The processor 184b may further include a plurality of preset chromaticities, each of the preset chromaticities corresponding to a brightness ratio of the first and second illuminating diodes. In the full-bright illumination mode or the preset illumination mode, the switch 224 is short-pressed to switch one of the preset chromaticities, and the preset chromaticity is replaced by the previously stored first brightness ratio information or the second The brightness ratio information drives the first and second light emitting diodes to generate bright light having a new brightness ratio.

In addition, in the full-bright illumination mode or the preset illumination mode, by long pressing the switch 224, the chromaticity adjustment mode is switched to perform chromaticity adjustment of the LED module 10.

The illumination system 4 of the fourth preferred embodiment of the present invention is substantially identical to the structure of the second embodiment described above, except that the input interface 24 of the present embodiment includes three switches 242, 244, 246. The switches 242, 244, 246 are electrically connected to the phase angle control module 16. Press For each of the switches 242, 244, 246, the phase angle control module 16 generates the delayed conduction angle corresponding to a particular angle of each of the switches 242, 244, 246. In addition, the illumination system 4 of the embodiment includes three sets of driving modules 262, 264, 266, and LED modules 282, 284, 286, and each of the driving modules 262, 264, 266 correspondingly determines the delayed conduction angle of a specific angle, thereby The driving modules 262, 264, 266 can detect the pressing states of the switches 242, 244, 246, and control the LED modules 282, 284, 286.

For example, when the switch 242 is pressed, the driving module 262 detects the corresponding angle of the delayed conduction angle and calculates the pressing time to control the LED module 282.

Of course, the number of switches of the input interface 24 in this embodiment is not limited to three, and three upper layers may be provided, and the same number of driving modules and LED modules are correspondingly disposed on the load end, and the same It can achieve the purpose of controlling multiple sets of LED modules on the control end.

In addition, in order to cope with the layout of the building, the lighting system of the first embodiment may be designed as the connection mode as shown in FIG. 6, and the two sets of the phase angle control module 16 and the switch 122 are disposed in the building. The different positions allow the user to control the LED module 10 at different locations. According to the same concept, the illumination systems of the second, third, and fourth embodiments can also be designed as the connection modes shown in FIG. 7 to FIG. 9, respectively, and the two sets of three-way switches 29 and the phase angle control module 16 are provided. And the input interfaces 12, 22, 24 are located at different positions in the building, and the user can control the LED module at different positions.

The illumination system 5 of the fifth preferred embodiment of the present invention includes a switch 30, an input interface 32, a phase angle control module 34, a drive module 36 and a light-emitting diode module. Group 38. The input interface 32 includes a variable resistor 322, and the phase angle control module 34 is electrically connected to the variable resistor 322, and is produced according to the resistance value of the variable resistor 322. This delayed conduction angle corresponding to the angle of the resistance of the variable resistor 322 is generated. In this embodiment, the larger the resistance value of the variable resistor 322 is, the larger the angle corresponding to the conduction angle is delayed; conversely, the smaller the resistance value is, the smaller the angle of the delayed conduction angle is, even if the variable resistor 322 is The resistance value is adjusted to 0 ohms, and the angle of the delayed conduction angle is greater than zero degrees, that is, the delayed conduction angle exists in the waveform of the electric energy output by the phase angle control module 34.

The processor 362 of the driving module 36 calculates the resistance value of the variable resistor 322 according to the angle of the delayed conduction angle detected by the phase angle detecting circuit 364. The control power conversion circuit 366 corresponding to the change in the resistance value outputs a corresponding electrical signal to the LED module 38 for control. For example, the brightness of the LED module 38 can be adjusted by using a change in the resistance value, or the chromaticity of the LED module 38 can be adjusted.

The illuminating system 6 of the sixth preferred embodiment of the present invention is substantially identical to the structure of the second embodiment, and includes a complex array driving module 40 and a light emitting diode module 42. Each of the driving samples includes a phase angle detecting circuit 402, a processor 404 and a power conversion circuit 406. Each group of the driving module 40 and the LED module 42 are installed at different positions. The user can use the switch 20 to simultaneously control the driving modules 40 to turn on or off the respective connected LED modules 42; press the switch 122 and simultaneously control each of the driving modules 40 according to the pressing time and the number of times. The processor 404 switches between different control modes, such as a full-bright illumination mode, a preset illumination mode, and a brightness adjustment mode.

In the brightness adjustment mode, the processor 404 of each of the driving modules 40 controls the connected power conversion circuit 406 to drive the light generated by the LED module to overlap with a first brightness value and a second brightness value. When the processor 404 determines that the state of the switch 122 is changed, the change of the brightness of the control is stopped, and the brightness value of the light generated by each of the LED modules 42 is recorded, instead of each of the processors 404. The preset illumination The original preset brightness value of the mode.

In actual use, the processors 404 may cause timing errors due to timing differences in the output signals of the processor 404 due to process variations, temperature variations, voltage instability, and other noise disturbances. As such, there will be an error in the time when the processors 404 each control the brightness change of the LED module 42 in the brightness adjustment mode. The longer or longer the brightness of the light-emitting diode modules 42 is changed, the more obvious the difference in brightness between the light-emitting diode modules 42 is, so that the state of the switch 122 changes each time. The current brightness values recorded by the processor 404 are different, and the LED modules 42 generate bright light of different preset brightness values.

In order to avoid the above situation, the embodiment further increases a synchronization mechanism in the brightness adjustment mode, so that the processors 404 can synchronously control the respective connected power conversion circuits 406 at the same time point. Each phase angle detecting circuit 402 detects the waveform of the electric energy output by the phase angle control module 16, and each of the processors 404 can obtain the period of the alternating current power source S, and a reference is taken from the period of the alternating current power source S. The point is used for synchronization, and this embodiment uses the first zero crossing in each cycle as the reference point. Each time the processor 404 measures the reference point, the power conversion circuit 406 is controlled to drive the light generated by the LED module 42 to increase or decrease a luminance difference.

For example, the first brightness value is "100", the second brightness value is "10", and the brightness difference value is "1"; after switching to the brightness adjustment mode, each of the processors 404 is in the AC power source S. When the first zero crossing point of the cycle, the power conversion circuit 406 is controlled to drive the LED module 42 to generate a brightness value of "100"; at the first zero crossing point of each subsequent cycle. , reduce one brightness difference "1" until the brightness value is "10", and then increase from the brightness value "10", each time the AC power S period increases by one brightness difference "1", Until the increase to the brightness value of "100", the next cycle is performed, thus repeatedly changing between the first brightness value and the second brightness value.

Therefore, the waveform of the AC power source S is used as a basis for synchronization, so that all the processors 404 can change the brightness value at the same time point every time, thereby effectively changing the brightness of the LED modules 42. The situation in which the brightness of each of the LED modules 42 is inconsistent when the respective processor 404 performs the brightness control of the LED module 42 is avoided. In practice, two zero-crossing points can be taken as the reference point of synchronization in each cycle of the AC power source S. Of course, the peak value in the waveform can also be used as the reference point, and the synchronization effect can also be achieved.

In practice, each of the LED modules 42 includes a plurality of first light emitting diodes and a plurality of second light emitting diodes, and the light color of the first light emitting diode is different from the second light emitting diode The color of the body. The control mode of each of the processors 404 further includes a chromaticity adjustment mode for adjusting the chromaticity of each of the LED modules 42. In each of the processor 404 operating in the chromaticity adjustment mode, the waveform of the AC power source S can also be utilized as a basis for synchronization, that is, each processor 404 changes each of the LEDs at a reference point in each cycle. The brightness ratios of the first light-emitting diodes and the second light-emitting diodes of the body module 42 are such that each of the light-emitting diode modules 42 can change the chromaticity synchronously at the same time point. The chromaticity of the light-emitting diode modules 42 is prevented from being different.

In the above embodiments, the lighting system and the phase signal transmitting device of the present invention are described by taking a light-emitting diode module as an example. The lighting system of the present invention can adopt other types besides the light-emitting diode module. The luminaires, such as fluorescent lamps and gas-fired lamps, only need to use corresponding power conversion circuits to drive the lamps for different types of lamps.

According to the above, the creation uses the phase signal transmission device composed of the phase angle control module and the driving module to transmit the state of the input interface through the power wave. The delayed conduction angle of the shape is transmitted from the control end to the load end to output a telecommunication number control lamp corresponding to the state of the input interface, that is, the signal is transmitted by using the waveform of the AC power source.
