Wireless dimmer with power detection

This creation is about a wireless dimmer, especially a wireless dimmer with power detection.

Light-emitting diodes (LEDs) have high luminous efficiency and energy-saving features, so most lighting fixtures have replaced traditional incandescent or fluorescent lamps with light-emitting diode lamps. Referring to FIG. 7, the LED lamp includes a general power supply 31 and an LED module 32. The general power supply 31 is an AC/DC power converter for converting the AC power supply VAC. The dimming output power source VDC is used to illuminate the LED module 32.

Because the foregoing general power supply 31 only outputs a fixed dimming output power VDC, the LED module 32 emits light only at a constant brightness. However, as the user's usage changes or the usage habits are different, the constant Brightness does not necessarily meet the needs of all users. To overcome the foregoing problems, referring to FIG. 8, a dimming power supply 33 having dimming input terminals D+, D-, dimming input terminals D+, D of a commercially available dimming power supply 33 can be used. - Dimming can be performed for analog (0~10V), digital pulse width modulation (PWM) or digital addressable interface (DALI). The dimming input terminal D+, D- is electrically connected to a dimmer 34, and the dimmer 34 can be a knob device embedded on the wall surface, and the user can rotate a knob of the dimmer 34 as needed. The dimmer 34 generates a dimming control signal Vd to the dimming input terminals D+, D- of the dimming power supply 33, and the dimming power supply 33 adjusts according to the dimming control signal Vd. The output dimming output power source VDC is used to adjust the brightness of the light emitting diode module 32.

Since the aforementioned dimmer 34 can be embedded on the wall or placed on the table, the user must personally approach the dimmer 34 and manually rotate the knob of the dimmer 34 to perform the dimming action. but In the age of the Internet of Things, this mode of operation has been clearly outdated. A cloud technology dimming using a mobile phone in the field is expected. On the other hand, when dimming using the conventional dimmer 34, I am usually on the scene, so there is no change in the light when dimming, and it can be recognized by the eyes. However, when using the mobile device in the field to dim the light, because the eyes can't see whether the light changes, the light is returned to the user, so that the user understands that the change of the light is necessary. This creation was born in response to this demand.

Therefore, the main purpose of the present invention is to provide a wireless dimmer with power detection, which is electrically connected to a dimming power supply, and the wireless dimmer with power detection includes: a wireless communication module The control chip includes a control chip and an antenna, the control chip receives a wireless dimming signal through the antenna, and generates a driving signal; a dimming circuit is electrically connected to the wireless communication module to receive the driving signal, and according to The driving signal outputs a dimming control signal to the dimming input end of the dimming power supply for dimming; a power circuit electrically connecting the wireless communication module and the dimming circuit to provide a working power supply; And a power detecting circuit, wherein the input portion and the output portion are electrically connected to the power input end of the dimming power supply and the control chip of the wireless communication module, and the power detecting circuit detects the dimming The power information of the power supply device is transmitted to the wireless communication module, and the control chip transmits the power consumption information through the antenna.

With the wireless dimmer setting, the user can directly or indirectly connect to the wireless communication module through a gateway through a smart phone or a tablet, thereby wirelessly controlling the creation. The wireless dimmer adjusts the brightness of the LED. In this way, the user can remotely dim the LED lamp without contacting the wireless dimmer, overcoming the local dimmer because the user is not in the local setting of the dimmer. The dimmer cannot be operated for dimming.

Furthermore, the present invention can instantly detect the current power consumption information (such as voltage, current, phase, power or power factor) of the LED device by using the setting of the power detecting circuit, and further can The power consumption information is externally transmitted to the user's smart phone or tablet computer, so that the user can know the instant power state of the light-emitting diode lamp; on the other hand, when the user performs the dimming action, the light is emitted. The voltage or current consumed by the diode lamp will change, and the power consumption information will naturally change accordingly. Therefore, the user can judge whether the dimming action is true from the instant power information presented by his smart phone or tablet. carried out.

In a possible embodiment, as shown in FIG. 2, the dimming circuit 14 is a digital dimming circuit, which may include a transistor Q and a resistor R. The transistor Q includes a first end and a first end. The two ends and a control end, for example, the first end, the second end and the control end are respectively a source, a drain and a gate of a field effect transistor (FET).

The resistor R is electrically connected between the second end of the transistor Q and the ground, and is electrically connected to The control terminal of the transistor Q is electrically connected to the output end of the control chip 131 between the dimming input terminals D+ and D- of the dimming power supply 21. The digital dimming control signal generated by the dimming circuit 14 can be a pulse width modulation (PWM) signal Vd, and the dimming power supply 21 adjusts according to a duty cycle of the PWM signal Vd. The dimming output power source VDC is output, thereby adjusting the brightness of the light emitting diode module 22. For example, when the LED module 22 is to be fully illuminated, the duty cycle of the PWM signal Vd can be maximized. Otherwise, the duty cycle of the PWM signal Vd can be adjusted to dim the LED. The brightness of the body module 22 is adjusted, for example, to a brightness of 90%, 80%, ..., 2%, 1%, etc. of the full-bright state, or the duty cycle of the PWM signal Vd is directly set to make the light-emitting diode Module 22 presents a particular brightness. In another possible embodiment, the digital dimming control signal generated by the dimming circuit 14 may also be a Digital Addressable Lighting Interface (DALI) instruction (hereinafter referred to as DALI instruction), and the DALI instruction will The brightness of the dimming required, for example, the brightness of 90%, 80%, ..., 2%, 1%, etc., is transmitted to the dimming input terminal D+ of the dimming power supply 21 through the DALI command signal format, D-, the LED module 22 is presented with a specific brightness according to the DALI command, wherein the dimming hardware circuit for implementing the DALI command is as shown in FIG. 2, and the modulation of the digital pulse width is adjusted.

Referring to FIG. 1 and FIG. 2 or FIG. 3, the input portion of the power detecting circuit 11 of the present invention is electrically connected to the power input terminals L1 and N1 of the dimming power supply 21, and the power detecting circuit 11 is used. The output portion is electrically connected to the input end of the control chip 131 of the wireless communication module 13. The power detecting circuit 11 can include an arithmetic unit 110, a current detecting resistor R1 and a voltage detecting resistor R2. The computing unit 110 includes a first input unit, a second input unit and an output unit, and each input unit. Contains a positive (+) and a negative (-). The current detecting resistor R1 and the voltage detecting resistor R2 are respectively connected in parallel to the first input portion and the second input portion of the computing unit 110.

Regarding the current loop of the present creation, the current generated by the live line L (Load) of the commercial AC power source VAC enters the power input terminal L1 of the dimming power supply 21, passes through the internal circuit of the dimming power supply 21, and then The other power input terminal N1 of the dimming power supply 21 outputs, and then returns to the neutral line N (Neutral) of the commercial AC power source VAC through the current detecting resistor R1, thereby forming a current loop. According to Kirchhoff's current law, the current in the same current loop is the same, and the current through the current detecting resistor R1 is equal to the current passing through the internal circuit of the dimming power supply 21. According to Kirchhew's voltage law, the mains AC power supply VAC is equal to the sum of the input voltage V _{L1N1 of} the dimming power supply 21 and the terminal voltage V _R1 of the current detecting resistor R1 (VAC=V _L1N1 + V _R1 ).

Regarding the voltage loop of the present creation, the live line L of the commercial AC power supply VAC and the neutral line N are connected in parallel to the voltage detecting resistor R2, so the terminal voltage V _{R2 of} the voltage detecting resistor R2 is equivalent to the voltage of the commercial AC power source VAC. . Further, according to the above formula VAC=V _L1N1 +V _R1 , the resistance value of the current detecting resistor R1 for measuring current is very small. Because the terminal voltage V _{R1 of} the current detecting resistor R1 is much smaller than the input voltage V _{L1N1 of} the dimming power supply 21, the terminal voltage V _{R1 of} the current detecting resistor R1 is in the above formula VAC=V _L1N1 +V _{R1 .} It can be neglected, so the commercial AC power supply VAC is approximately equal to the input voltage V _{L1N1 of} the dimming power supply 21, and the terminal voltage V _{R2 of} the voltage detecting resistor _R2 can be regarded as equivalent to the voltage of the commercial AC power supply VAC. It is regarded as the input voltage V _L1N1 equivalent to the dimming power supply 21 .

The calculation of the effective value voltage (Vrms), the effective value current (Irms), the actual used power (Watt), and the power factor (PF) will be described below.

1. RMS voltage (Vrms)

(The v (t) represented by the following), after sampling the divided voltage v (t) is calculated, and the square is accumulated according to the utility power AC voltage VAC is generated in the detecting resistor R2 voltage V _R2, divided by the period T takes the average value, and then the above calculation result is turned on, to calculate the effective value of the input voltage V _L1N1 of the dimming power supply 21, as follows:

2. RMS current (Irms)

According to the terminal voltage VR2 generated by the commercial AC power supply VAC at the current detecting resistor R1, the current of the commercial AC power supply VAC (hereinafter referred to as i ( t )) may be reflected, and the current i ( t ) is divided and sampled and squared. Performing the accumulation, dividing by the period T to take the average value, and then opening the number of the above calculation results, the rms current of the dimming power supply 21 can be calculated as follows:

3. Actual power (Watt)

The aforementioned voltage v ( t ) is multiplied by the current i ( t ) and then accumulated, and finally averaged to obtain the actual used power (Watt), as follows:

4. Power factor (PF)

According to the aforementioned actual power (Watt), voltage v ( t ) and current i ( t ), the power factor can be obtained as follows:

In this way, since the two input portions of the computing device 110 are electrically connected to the power input terminals L1 and N1 of the dimming power supply 21, the terminal voltages of the current detecting resistor R1 and the voltage detecting resistor R2 can be Reflecting the current and voltage consumed by the LED lamp, the power detecting circuit 11 can instantly detect the current power consumption information (such as voltage, current, phase, power or power factor) of the LED lamp. The power information is transmitted to the control chip 131 of the wireless communication module 13, and the control chip 131 transmits the power information through the antenna 132 directly or through the gateway to the user's smart phone or Displayed on the tablet. Therefore, the user can not only know whether the current LED lamp is lit from the data of the power information presented by the smart phone or the tablet, but also know the power consumption information of the LED lamp (for example) Voltage, current, phase, power or power factor, etc.).

Referring to FIG. 4, the wireless communication module 13 of the wireless dimmer 100 with the power detection can directly connect the user's mobile device 15 (such as a mobile phone or a tablet), and the user can operate the mobile device 15 pairs. The wireless dimmer 100 issues a dimming command to achieve a dimming function. On the other hand, please Referring to FIG. 5, the wireless communication module 13 of the wireless dimmer 100 of the present invention can be connected to a gateway 16, and the user's mobile device 15 connects the gateway 16 to make the mobile device. 15 is indirectly connected to the present wireless dimmer 100 through the gateway 16 , so that the mobile device 15 can transmit a dimming command to the created wireless dimmer 100 through the gateway 16 . The gateway 16 can be further connected with other household appliances (such as air-conditioning, electric appliances, curtains, sockets, etc.), so that the mobile device 15 can operate other household appliances in addition to dimming, and achieve wisdom. The efficacy of the home (Smart Home).

The present wireless dimmer 100 has a dimming function, in other words, the output power of the dimming power supply 21 is adjusted in a wattage adjustment interval. For example, the full power output of the dimming power supply 21 corresponds to a maximum wattage (100%) of the wattage adjustment interval, and the half power output of the dimming power supply 21 corresponds to the highest wattage. Half (50%), the low power output of the dimming power supply 21 corresponds to a minimum wattage (20%) of the wattage adjustment interval, and so on. However, the dimming power supply 21 does not have to have full power output. For example, the dimming power supply 21 has a full power output of 500 watts, and the user-installed LED module 22 can only withstand 300. The tile can not withstand 500 watts, so the present wireless dimmer 100 also has the function of adjusting the maximum power output of the dimming power supply 21, wherein the first end of the transistor Q of the dimming circuit 14 is The magnitude of the received voltage is used to adjust the maximum power that can be output by the dimming power supply 21, as explained later.

Referring to FIG. 6, the dimming power supply 21 can simultaneously receive analog dimming (such as 0~10V driving signal) and digital dimming (such as PWM dimming driving signal), and the dimming circuit 14 is powered. A variable resistor 17 is connected in series between the first end of the crystal Q and the output terminal of the power supply circuit 12, assuming that the output voltage of the power supply circuit 12 is 10V. When the dimming power supply 21 is to be at the full power output (for example, 500 W), the variable resistor 17 can be adjusted to a minimum resistance value, so that the variable resistor 17 is equivalent to a short circuit. The first terminal voltage of the transistor Q of the optical circuit 14 is 10V outputted by the power supply circuit 12, and the terminal voltage of the resistor R (or the PWM signal Vd) is a maximum value and is fed back to the dimming. The power supply 21 is such that the dimming power supply 21 is up to full power output. When the maximum power that can be outputted by the dimming power supply 21 is reduced, for example, 300 W, the resistance value of the variable resistor 17 can be adjusted to divide the voltage to make the transistor Q of the dimming circuit 14 The first terminal voltage is reduced to 6V, and the terminal voltage of the resistor R (or the PWM signal Vd) is correspondingly reduced and fed back to the dimming power supply 21, so that the dimming power supply 21 can be The maximum power that can be output is reduced to 300W.

In this way, the duty cycle of the PWM signal Vd is further adjusted, so that the wattage adjustment interval can scale up or down the output power of the dimming power supply 21 as a fine adjustment wattage adjustment interval 0~100. % corresponds to the dimming operation of 0 to 300 W output by the dimming power supply 21. Please refer to the following table to reduce the maximum wattage that the dimming power supply 21 can output to 300 watts without 500 watts for full power output.

Referring to FIG. 6 again, a controllable switch 18 is connected in series between the power detecting circuit 11 and the power input end (L1 or N1) of the dimming power supply 21, and the controllable switch 18 is electrically connected. The wireless communication module 13 is controlled by the wireless communication module 13, and FIG. 6 is an example of connecting the power input terminal N1. When the wireless dimming signal received by the wireless communication module 13 is 0%, the wireless communication module 13 can send a control command to the controllable switch 18 to cut off the power input of the dimming power supply 21. In order to completely save power. Since the minimum power consumption (for example, 0.5 W) is still achieved even when the dimming power supply 21 is adjusted to 0%, the advantage of cutting off the input power of the dimming power supply 21 through the controllable switch 18 is that it can be completely Avoid power consumption. On the other hand, when the dimming control signal Vd received by the dimming input terminals D+, D- of the commercially available dimming power supply 21 is 0%, the dimming output power supply VDC theory should be It is 0V, but actually outputs a small voltage, which will cause the LED module 22 to be slightly bright. Therefore, the benefit of the controllable switch 18 allows the dimming output power supply VDC to be truly 0V, so that the illumination The diode module 22 is actually extinguished.

As described above, since the power detecting circuit 11 detects the power consumption information of the light-emitting diode lamp, the data of the power information displayed by the user's smart phone or tablet can naturally reflect the light. The immediate power state of the diode lamp. When the user performs the dimming action, the user can also judge whether the dimming action is actually performed from the instant power information presented by the smart phone or the tablet. For example, when the user performs the dimming action through the smart phone, and the data such as the current, voltage or power of the light-emitting diode lamp presented by the smart phone changes, the representative dimming action is actually performed; After the user performs the dimming action through the smart phone, the data such as the current, voltage or power of the light-emitting diode lamp presented by the smart phone does not change, which represents a mistake of the dimming action, and the user can further Check for problems with the LEDs and repair them. In the cloud control application, the back-end means of the aforementioned power information is necessary. For example, when the user performs dimming using the conventional dimmer described in the prior art, the user can use the naked eye because the user is on site. See the change in dimming. However, when using cloud dimming, the user may be in Taipei, and the dimming destination is in Kaohsiung, which may cause the user to see the dimming change with the naked eye. Therefore, the creation allows the user to adjust the current, voltage or power after dimming. The data has changed and the result of the dimming is known.

In addition to the foregoing mobile device that reports the power information to the user, the wireless communication module 13 of the present wireless dimmer 100 can also have a built-in temperature sensor (not shown) and accept the user's settings. The alarm threshold function of the electricity information and the working temperature, when the wireless communication module 13 determines the power consumption information or the working temperature exceeds an alarm threshold, an error alarm function is issued (for example, by using a mobile phone or a lithographic or alarm bell or a light signal) An error alert is issued). On the other hand, the wireless communication module 13 can also report the wireless receiving power (dbm) status to the user's mobile device, so that the user can grasp the working state of the created wireless dimmer 100 (including the power consumption information, Operating temperature and wireless reception quality).

In summary, the wireless dimmer 100 with power detection can make the traditional dimmer become a cloud dimmer, and is suitable for the dimming power supply 21 commonly used in the market (digital PWM, digital) The DALI command, analog 0~10V, or its hybrid type, allows these dimming power supply manufacturers to use the creation of the cloud directly for cloud dimming, which is industrially useful. Moreover, the wireless dimmer 100 with the power detection can also detect the power consumption information, the working temperature and the wireless receiving quality, so that the user can fully understand the working state of the light-emitting diode lamp. And by setting the alarm threshold, if the wireless dimmer 100 that uses the power detection detects that the alarm threshold is exceeded, the alarm will be actively issued, so that the maintenance personnel can perform the maintenance operation, as a whole, regardless of the adjustable power supply. Manufacturers, users and maintainers are extremely convenient and practical inventions. The system does have patent requirements such as industrial utilization, novelty and advancement, and applies for patents according to law.
