Method and device for driving high-efficiency lamp by means of electronic transformer

Abstract

The invention discloses a method and a device for driving a high-efficiency lamp by means of an electronic transformer. The device comprises a commercial power filtering input end which is used for converting AC power to high-voltage DC power; a flyback switch unit which is used for converting high-voltage DC power to low-voltage DC power; a light and color adjustment driving unit which is used for making an LED light source emit light with different colors and brightnesses, wherein the light and color adjustment driving unit comprises a DC / DC adaptive power supply module, a power-off detecting module, a wireless communication module, a micro processing control unit, an LED driving module and an overload protecting unit; an electric memory, a current detecting unit, a current control unit and an electric consumption amount detecting unit. According to the method and the device, an electric memory is utilized for memorizing illumination color or brightness switching which is set by a user to an illumination system, thereby realizing no related data loss after restarting, and realizing light and color adjustment of the lamp by a mobile phone through a wireless network. Compared with a traditional mechanical switch, the method and the device have advantages of higher convenience and higher intelligent degree.

Description

technical field [0001] The invention belongs to the field of smart home, and in particular relates to a method and a device for driving high-efficiency lamps by using an electronic transformer. Background technique [0002] With the rapid rise of home decoration and the gradual formation of modern home decoration concepts, the current market is in urgent need of a high-grade, multi-channel, high reliability, centralized management, decentralized control intelligent remote operation lighting application electronic transformer drive device . At present, most household lighting switches are mechanical switches, and the switches are scattered, inconvenient to operate, and affect the decoration effect. A small number of infrared lighting switches are used in the market. Due to poor directivity of infrared rays, short control distance, and inability to control through obstacles, they are greatly restricted and difficult to promote. [0003] To sum up, the problems existing in th...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing high-efficiency lamps have a small number of radio control technology, but due to the small number of receiver control channels, the overall installation is relatively scattered; the panel buttons are backward and easy to pollute; the remote control transmitter Too large, inconvenient to carry; complex control settings, inconvenient adjustment; poor filtering effect on current, less control channels, poor safety and stability; and it is difficult to realize remote telephone or computer network control
