[0029] Detailed description will be given below in conjunction with the drawings.

[0030] Such as figure 1 As shown, the present invention provides an LED lighting device. The LED lighting device includes a wireless communication relay device 10, a light source driving module 30, a control unit 20, and a light source module 40. The LED lighting device further includes a power supply module 50. In the present invention, a preset power value is pre-stored in the control unit 20 for each working state of the light source module 40. The light source driving module 30 is integrated and/or connected to the light source module 40, and the light source driving module 30 is used to adjust the color temperature and brightness of the light source module 40, and turn the light source module on or off. The preset power value further includes the power value of the light source driving module 30 and the wireless communication relay device 10. The light source module 40 is tested in the early stage to obtain the power value of the light source module 40 in different working states, and the power value corresponding to each working state is stored in the control unit 20 in advance. The working state is that the LED lighting device has different brightness and/or color temperature.

[0031] The control unit 20 calculates the power consumption of the LED lighting device according to the lighting characteristic adjustment instruction sent to the light source driving module 30 via the wireless communication relay device 10 and based on the time parameter of the sending instruction and the preset power value. The wireless relay communication device includes at least a data storage and processing module 102 and a WIFI communication module 101. The data storage and processing module 102 is used to perform preliminary processing and storage of signals received by the wireless communication relay device 10. The user can realize the dimming and color adjustment of the LED lighting device through the WIFI communication module 101 on the one hand, and on the other hand realize the wireless Internet access of smart terminals such as mobile phones and computers. Specifically, the user terminal 60 sends a control instruction to the LED lighting device, and the wireless communication relay device 10 receives the control instruction sent by the user and performs corresponding operations based on the control instruction. For example, the control instruction is to connect to the wireless network, and the wireless communication relay device 10 opens the connection channel with the smart terminal. If the control instruction is to adjust the brightness/color temperature of the LED lighting device, the wireless communication relay device 10 sends the instruction to the light source driving module 30 to drive the light source module 40 to adjust the brightness/color temperature.

[0032] The LED lighting device has at least one of the on and/or off states of the light source module 40 and/or the wireless communication relay device 10. Specifically, the working status of the LED lighting device includes but is not limited to the following situations: light source module 40 is on, wireless communication relay device 10 is off; light source module 40 is off, wireless communication relay device 10 is on; light source module 40 is on, wireless The communication relay device 10 is on; the light source module 40 is off, and the wireless communication relay device 10 is off. The user changes the working state of the LED lighting device according to actual application needs and environmental conditions. For example, in an environment with sufficient lighting, the light source module 40 can be selectively turned off, and the wireless communication relay device 10 can be turned on or off. When no network connection is required, the wireless communication relay device 10 can be selectively turned off, and the light source module 40 can be turned on or off. The various working states of the LED lighting device are represented by patterns of different colors and shapes. For example, a circular sign indicates that the light source module 40 is off and the wireless communication relay device 10 is on; a semicircle sign indicates that the light source module 40 is on and the wireless communication relay device 10 is on. On; the triangle indicates that the light source module 40 is on and the wireless communication relay device 10 is off; the square indicates that the light source module 40 is off and the wireless communication relay device 10 is off. The present invention includes but is not limited to the above-mentioned graphical representation. Users can control the LED lighting device more conveniently and intuitively through the above signs.

[0033] The wireless communication relay module further includes a second communication module 103, which is a Zigbee module or a Bluetooth module. The second communication module 103 has the advantages of low power consumption, fast speed, and reliability. The high-power WIFI communication module 101 is turned off when the wireless network connection is not required, and the low-power second communication module 103 is used to control the lighting characteristics of the LED lighting device. Adjust to further energy saving and environmental protection. Furthermore, the user terminal 60 can open the WIFI communication module 101 through the second communication module 103.

[0034] The control unit 20 is provided with at least one brightness and/or color temperature level parameter for adjusting the lighting characteristics of the light source driving module 30, and the light source module 40 has a corresponding working state by selecting the brightness and/or color temperature level parameter. The user changes the brightness and/or color temperature parameters of the LED lighting device according to actual or environmental requirements, and sets the brightness levels in the control unit 20 as L1, L2...Lm, m≥1 and the color temperature levels as K1, K2...Kn, n≥1, for example : 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K, 6500K. One brightness level can correspond to different color temperature levels, and one color temperature level can correspond to different brightness levels. The light source driving module 30 has m×n working states, and each working state is set with a corresponding preset power value. At the same time, the average power value of the wireless communication relay device 10 is stored in the control unit 20. When the control unit 20 detects that the wireless communication relay device 10 is off, it subtracts the wireless communication relay device 10 from the preset power value. The average power value of the LED lighting equipment can obtain the actual power consumption value of the LED lighting equipment, which makes the statistical results more accurate. In practical applications, preset the power consumption of the LED lighting equipment, and only need to get the working time corresponding to each working state to get the power consumption of the LED lighting device in a specific time period, which reduces the complexity and power consumption of the circuit The accuracy of volume statistics.

[0035] The user terminal 60 sends the control instruction to the light source driving module 30 through the wireless communication relay device 10 integrated and/or connected in the LED lighting device. The wireless communication relay device 10 only responds to a lighting characteristic adjustment instruction to one user terminal 60 at the same time. In order to prevent the LED lighting devices from being unable to respond to the user terminal 60 by adjusting the lighting characteristics of multiple users 60 and multiple LED lighting devices at the same time, it is set that only one user can adjust the lighting characteristics at the same time. Before the user terminal 60 sends the lighting characteristic adjustment instruction, it first sends a request adjustment signal to the LED lighting device, and the user terminal 60 performs the lighting characteristic adjustment after receiving the request permission signal, otherwise the LED lighting device rejects the lighting characteristic adjustment.

[0036] At the same time, the wireless communication relay device 10 provides network data transmission services for at least one user terminal 60. At the same time, in order not to affect the wireless Internet access of multiple users, one LED lighting device can provide network data transmission services for multiple users.

[0037] The control unit 20 detects whether the control command includes a lighting characteristic adjustment command, and records the time parameter of the lighting characteristic adjustment command. The control instructions sent from the user terminal 60 to the LED lighting device not only include adjustments to lighting characteristics, but also include at least a wireless network connection signal, a lighting characteristic adjustment instruction, a power consumption statistics signal, and/or a power consumption comparison signal. Including fault detection signal and power consumption graphic display signal. The lighting characteristic adjustment command includes a color temperature adjustment signal, a brightness adjustment signal, and a signal for opening and closing the light source module.

[0038] After the wireless communication relay device 10 receives the control instruction, the data storage and processing module of the wireless communication relay device 10 performs preliminary preprocessing of the control instruction, and the control unit 20 recognizes and detects the preprocessed control instruction, and judges Whether the control command includes a lighting characteristic adjustment command, and if it includes a lighting characteristic adjustment command, the control unit 20 records the time parameter of the control command including the lighting characteristic adjustment command. In this way, the working state time of the LED lighting device can be accurately counted, so as to accurately count the power consumption of the LED lighting device.

[0039] The time parameter is the time when the wireless communication relay device 10 sends the lighting characteristic adjustment instruction, and the control unit 20 obtains the time interval between sending each lighting characteristic adjustment instruction based on the time parameter. The time interval is the absolute value of the difference between the time parameters of two or more lighting characteristic adjustment commands. The control unit 20 detects the working state of the light source driving module 30 within the time interval and searches for the preset power value corresponding to the working state. The control unit 20 further includes a power consumption analysis and statistics unit 201. The power consumption analysis and statistics unit 201 calculates the first power consumption of the LED lighting device in the time interval according to the time interval and the preset power value.

[0040] Specifically, after the control unit 20 detects that the wireless communication relay device 10 sends a lighting characteristic adjustment command, it records the time parameters of the command, and then detects the working state of the light source drive module 30 after the command is sent. The working state is The corresponding preset power value is searched from the preset power value in the control unit 20 and output to the power consumption analysis and statistics unit 201. When it is detected again that the wireless communication relay device 10 sends a lighting characteristic adjustment instruction to the light source driving module 30, or when the working state of the light source driving module 30 changes, record the time parameter of the lighting characteristic adjustment instruction or the time when the working state changes, The power consumption analysis and statistics unit 201 obtains the first power consumption of the LED lighting device within the time interval based on the difference between the two time parameters and the power preset value obtained by the search. At the same time, the control unit 20 detects that the wireless communication relay device 10 is in an on or off state within the time interval. If the wireless communication relay device 10 is in the off state, when calculating the first power consumption, the power consumption analysis and statistics unit 201 subtracts the preset power value in the time interval from the pre-stored wireless communication relay device 10 Average power value. The first power consumption obtained in this way is more in line with the actual situation and more accurate.

[0041] In practical applications, the user can roughly understand the power consumption of the LED lighting device in a certain period of time through the first power consumption, for example, the power consumption can be displayed intuitively through a combination of graphics or colors. The green circular mark indicates low electricity consumption, the yellow triangle mark indicates that the electricity consumption is at a medium level, and the red five-star price indicates high electricity consumption. The present invention includes but is not limited to the above-mentioned power consumption display mode. Through the above method, the user can intuitively and vividly obtain the power consumption of the LED lighting device in each working state, and then select the working state with lower power consumption according to the situation, which is more energy-saving and environmentally friendly. In addition, the average power of the incandescent lamp or energy-saving lamp is stored in the control unit 20, and the power consumed by the incandescent lamp or energy-saving lamp in the corresponding time period is obtained based on the time parameter. Energy saving situation.

[0042] figure 2 It is a block diagram of another preferred embodiment of the present invention. Such as figure 2 As shown, this embodiment and figure 1 Compared with the illustrated embodiment, the difference lies in that this embodiment further includes a fault alarm module 202, a current detection module, and a timing module 203. The current detection module and the timing module 203 can realize the power consumption statistics and fault detection of each module of the LED lighting device. The fault alarm module 202 is used for judging whether the LED lighting device has a fault according to the power consumption of the LED lighting device and generating a corresponding fault warning signal. The fault warning signal is fed back to the user terminal 60 through the wireless communication relay device 10 or sent to the light source driving module 30 through the fault warning module 202 to drive the light source module 40 to send out the warning light. Specifically, when the control unit 20 detects that the WIFI communication module 101 is damaged, it can feed back a fault alarm signal to the client through the second communication module 103, or drive the light source module 40 to emit a fault alarm prompt light to prompt the user to appear in a more intuitive and vivid manner. malfunction. The fault alarm signal includes at least the faulty module, the time and type of fault.

[0043] The current detection module detects the current flowing through the LED lighting device, the wireless communication relay device 10 and the light source driving module 30. The current detection module includes a first current detection module 301, a second current detection module 302, and a third current detection module 303. The first current detection module 301 detects the current of the LED lighting device, the second current detection module 302 detects the current flowing through the wireless communication relay device 10, and the third current detection module 303 detects the current flowing through the light source driving module 30 and the light source module 40 . The power consumption analysis and statistics unit 201 obtains the power consumption of the LED lighting device, the wireless communication relay device 10 and the light source driving module 30 according to the current and/or voltage. Specifically, in practical applications, the input voltage U0 is fixed, the AC/DC conversion efficiency of the power module 50 is also fixed η, and the output voltage U1 is also fixed. Therefore, it is necessary to measure each module and the total current. The current detection module adopts a test resistance whose resistance is negligible compared with the resistance of the light source driving module 30 and the wireless communication relay device 10. The specific options are 1 ohm, 0.1 Euro or 0.01 Euro. The first current detection module 301 measures the first current I1 of the LED lighting device, and obtains the power consumption of the LED lighting device P1=U1×I1. The second current detection module 302 measures the current I2 of the wireless communication relay device 10, and the third The current detection module 303 measures the current I3 of the light source driving module 30 and the light source module 40, and the powers of the wireless communication relay device 10 and the light source driving module 30 are calculated to be P2 and P3, respectively, where P2 and P3 pass P2= P1×I2/(I2+I3) and P3=P1×I3/(I2+I3) are calculated. The control unit 20 includes a timing module 203 for counting the power consumption time of the light source module, the wireless communication relay device, and the light source driving module and output to the power consumption analysis and statistics unit 201. Specifically, when the control unit 20 detects that the LED lighting device starts to work, it starts the timing module 203; when it detects that the operation of the LED lighting device changes, the timing module 203 outputs the measured power consumption time to the power consumption analysis and statistics unit 201. Every time the working state of the LED lighting device changes, the timing module 203 sends the power consumption time measured once to the power consumption analysis and statistics unit 201.

[0044] The power consumption analysis and statistics unit 201 obtains the second power consumption of the LED lighting device, the third power consumption of the wireless communication relay device 10, and the light source driving module 30 according to the power consumption time and the power consumption of each module during the power consumption time. And the fourth power consumption of the light source module 40.

[0045] Further, the power consumption analysis statistical unit 201 determines whether the LED lighting device needs to be debugged and/or corrected according to the absolute value of the difference between the first power consumption and the second power consumption of the LED lighting device. The first power consumption is calculated by the preset power value of each working state and the duration of each working state. On the premise that the LED lighting device is not damaged, the first power consumption is theoretically closer to the actual LED lighting device power consumption.

[0046] The second power consumption is based on the traditional method of measuring current and voltage. In order to further ensure the accuracy and reliability of the first power consumption, the user can verify the accuracy and reliability of the first power consumption through the second power consumption. Specifically, it is judged whether the absolute value of the difference between the two is within the allowable error range. If the difference between the two is outside the allowable error range, it can be preliminarily determined that the LED lighting device is malfunctioning, and the control unit 20 further determines the specific malfunctioning location. The control unit 20 judges the working status of the wireless communication relay device 10 and the light source driving module 30 based on the third power consumption and the fourth power consumption. Specifically, the control unit 20 stores the power consumption range of the wireless communication relay device 10 and the light source driving module 30 during normal operation, obtains the normal power consumption range for the set time period from the normal power range, and determines the third power consumption Whether and the fourth power consumption are within their respective normal power consumption ranges. For example, if the fourth power consumption does not belong to the normal power consumption range of the light source driving module 30, it means that the light source driving module 30 is damaged. The fault alarm module generates a fault alarm signal of the light source driving module 30 and feeds it back to the user terminal 60 or drives the light source module 40 to emit a corresponding warning light. The warning light can be evenly spaced or non-uniformly spaced flashing, color or brightness change.

[0047] In another specific implementation manner, the control unit 20 may also separately count the power consumption of the WIFI communication module 101 in a set time period. The control unit 20 further pre-stores the power value corresponding to the flow value of the WIFI communication module 101 under the corresponding bandwidth. Specifically, under the condition of a certain bandwidth, the corresponding power consumption value of the WIFI communication module 101 is preset according to the flow value of the WIFI communication module 101. For example, set to P1 under 1M bandwidth 1 , P1 2 ,...P1 i , Set to P2 under 2M bandwidth 1 , P2 2 ,...P2 i. The power consumption analysis and statistics unit 201 obtains the power consumption of the WIFI communication module 101 according to the flow value and the time period set by the user. Specifically, within a set time period, the control unit 20 collects the flow value of the WIFI communication module 101 at a uniform interval Δt, and queries the power value corresponding to the flow value under the current bandwidth. The power consumption analysis statistical unit 201 obtains the power consumption of the WIFI communication module 101 at the time interval △t by multiplying the found power value and the time interval △t, which is specifically W i =P i *△t, from which the power consumption of the WIFI communication module 101 in the time period set by the user can be obtained, specifically W=∑P i *△t.

[0048] Further, the first power consumption, the second power consumption, the third power consumption, the fourth power consumption and the power consumption of the WIFI communication module are stored in the dynamic random access memory DRAM. When the user turns off the WIFI communication module 101 or suddenly loses power, the data in the DRAM will be automatically saved to the external storage device. The external storage device can be a Flash chip or a ferroelectric FRAM chip. Avoid the situation that all data in DRAM is cleared when the power is off or when a fault occurs. After the WIFI communication module 101 returns to the normal working state, the control unit 20 then reads the latest stored power value from the external storage device. The user can set the time for counting the WIFI communication module 101 as needed, such as one month or one day. The timing module 203 performs timing. When the statistical time reaches the statistical time set by the user, the data in the DRAM is synchronously updated to the external storage device. The WIFI communication module 101 or the second communication module 103 then sends the power consumption data in the external storage device to the user terminal. And while sending the power consumption data, it reminds the user of the information interaction of the power consumption by means of periodic or aperiodic flashing and/or emitting a specific color light. The user can also set the power consumption threshold for a certain period of time. When the power consumption of the period reaches the threshold set by the user, the WIFI communication module 101 sends a prompt message to the user that the set power consumption has been reached. In addition, the light source module 40 emits a reminder light that the set power consumption has been reached, which can specifically be in the form of periodic or non-periodic conversion of brightness, color change, interval flashing, and emission of light of a specific wavelength.
