Embodiment 1

[0052] Such as figure 1 As shown, an LED lighting device includes an LED driving circuit, a wireless communication module and a control module. The LED driving circuit includes an LED driving module and an LED light source module. The control module is integrated with a power consumption statistics module. The power consumption statistics module has the function of calculating and storing data related to power consumption. The brightness of the light source module has multiple levels, for example, from L1, L2...Li. There are various color temperatures of the light source module, from a, b...x. Different luminances and different color temperatures of the light source modules combine with each other to form different working conditions of the LED lighting device. In the normal working state of the LED lighting device, test the power value of the wireless communication module, control module and LED drive circuit of the LED lighting device in the corresponding working conditi...

Embodiment 2

[0067] This embodiment is a preferred embodiment of the present invention, and only the implementation manners different from Embodiment 1 are described, and the same implementation manners will not be repeated.

[0068] Such as figure 2 The schematic diagram of an LED lighting device shown includes a wireless communication module and an LED driving circuit. The control module is an MCU module, and the LED drive circuit includes a constant voltage source module with adjustable output voltage, a constant current control module, a PWM dimming signal module and an LED light source module. The wireless communication module is connected with the APP client and the cloud server through wireless signals. The MCU module pre-stores the predicted power value of each circuit module of the LED lighting device, the predicted power value of the wireless communication module and the predicted power value of the LED light source module in each working condition. The predicted power value i...

Abstract

The invention relates to an LED lighting device. A wireless communication module and a control module are integrated in the LED lighting device, and the control module selects and uses corresponding working conditions of the LED lighting device according to user-specified lighting parameters provided by the wireless communication module. The LED lighting device is characterized in that an LED drive circuit is connected to at least one sampling circuit as required, the at least one sampling circuit is used for analyzing power consumption, and the control module analyzes corresponding actual power consumption acquired through test of the at least one sampling circuit on the basis of predicted power consumption corresponding to working conditions and stores the actual power consumption by corresponding to the working conditions. The electric power of the wireless communication module and various working conditions of the LED lighting device can be measured in a detailed manner; the statistical errors of the power consumption of the LED lighting device are reduced; the power consumption condition of the LED lighting device is analyzed by the sampling circuit, and the LED drive circuit is monitored and corrected.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to an LED lighting device. Background technique [0002] At present, lighting devices in the field of lighting basically have a single lighting function or a lighting device with a dimming function. What is relatively new is the lighting device represented by Philips Hue, which has a short-range mobile phone control dimming function. The lighting device can control the dimming function of the lamp through the mobile app, and at the same time, it can derive the light simulation of some life scenes, and also add the effect of voice control. But there are few reports mentioning the LED lighting device with Internet access function, especially the wifi relay type Internet access function. Sengled company recently launched an LED lamp with Internet access function. On the one hand, the lamp is bulky and has low versatility in practical applications, which is limited in many household li...
