Embodiment 1

[0045] In this embodiment, the lighting device with communication function is an LED lamp, which includes a WiFi module, a light source driving module and a light source module. There is a wireless connection between the WiFi module in the LED lamp and the terminal. After receiving the instruction related to the adjustment of lighting characteristics sent by the terminal, the WiFi module sends a signal instruction to the light source driving module to drive the light source module to execute the corresponding dimming instruction. The aforementioned lighting characteristic adjustment includes but not limited to: turning on / off the light emitting unit of the light source module, adjusting light color, brightness, color temperature and set brightness, color and color temperature periodic change parameters.

[0046] Standard power data corresponding to a specific light source state is pre-stored in the WiFi module. The foregoing light source state includes: a combination of on and...

Embodiment 2

[0052] On the basis of Example 1, such as figure 1 As shown, a test resistor R1 is provided on the power supply circuit of the lighting device. At the same time, test resistors R2 and R3 are respectively set on the branches connected to the WiFi module and the light source driving module to measure the circuit current data I1, I2 and I3. Wherein, the aforementioned test resistors R1 , R2 , and R3 are all small resistors, such as 0.01 ohm and 1 ohm. In this way, the power consumption of the test resistors R1, R2, and R3 can be ignored, and it is also convenient for calculation and processing.

[0053] A timer is also provided in the WiFi module, preferably, the timer is built in the processing chip of the WiFi module. The timer is used to count the power consumption time under each working power, and store it in the WiFi module as the second working time data. In use, the output voltage U1 is determined by the input voltage U0 and the power conversion efficiency η. Output p...

Embodiment 3

[0058]As an improvement and supplement to Embodiments 1 and 2, the user can make settings related to power consumption through the app or computer software on the terminal, including but not limited to: power consumption data feedback cycle, power consumption set value, power consumption How to interact with excess power. For example, the user selects a set value of power consumption and / or an interaction mode within a specific time period according to needs, and the setting information is sent to the WiFi module. The WiFi module compares the power consumption statistical data with the power consumption set value regularly or irregularly. When the WiFi module determines that the power consumption within the set time period exceeds the set value, the WiFi module outputs a corresponding dimming signal command to the light source driving module according to the setting information related to the interaction mode, so that the light source module performs interactive actions. At t...

Abstract

The invention relates to a power consumption statistics method of a lighting device with a communication function and the lighting device. There is signal transmission between the WiFi module and the light source driving module in the lighting device. The statistical data of electricity consumption of the lighting device is calculated by the WiFi module according to the first working time data determined by the signal command transmission time interval and the preset standard power data corresponding to the state of the specific light source, that is, the first Power consumption: judging the operating state of the lighting device according to the difference between the first power consumption and the second power consumption obtained by processing the circuit current data and the second working time data. The invention not only improves the accuracy of electricity consumption statistics of the lighting device, but also realizes the monitoring of the running state of the lighting device.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a lighting device with a communication function and a power consumption statistics method thereof. Background technique [0002] The current lighting devices basically only have a single lighting and dimming function, and few LED lighting devices have the Internet access function, especially the WiFi relay type Internet access function. Moreover, none of the existing lighting devices with the Internet access function has the power consumption statistics function for the Internet access module, the light source module and the entire lighting device. Very few LED lighting patents mention the statistics of power consumption, but they all assume that the power is constant, and without adjusting the brightness and color temperature, very rough statistics of power consumption do not have correction and monitoring functions, so , its practical value is very limited.
