Abstract

The invention discloses an energy-saving lamp wireless networking system with ultra wideband communication and a method thereof. The energy-saving lamp wireless networking system comprises a controller and an energy-saving lamp; a UWB unit is arranged in the energy-saving lamp, and comprises an MCU I, a UWB communication module I, and an antenna I; the MCU I is connected with the UWB communication module I which is connected with the antenna; the controller comprises a display screen, keys and a remote controller of a UWB control unit; the UWB control unit comprises an MCU II, a UWB communication module II and an antenna II; the MCU II is connected with the UWB communication module II which is connected with the antenna II; and information transmission between the controller and the energy-saving lamp is carried out through a UWB communication protocol. The energy-saving lamp wireless networking system has simple and flexible wiring and strong expandability, and is controlled by the mobile controller; the on / off of the lamp and scenes are controlled flexibly and conveniently; and the power of a dimmable electronic ballast can be adjusted according to requirements.

Description

technical field [0001] The invention relates to a control system for an energy-saving lamp, in particular to a UWB wireless networking system and method for an energy-saving lamp, and belongs to the technical field of electric lighting. Background technique [0002] In the application of modern lighting fixtures, electronic ballasts are used more and more widely. An electronic ballast is a converter that converts power frequency AC power into high frequency AC power. Its basic working principle is: power frequency power becomes DC power after filtering and rectification. Then through the DC / AC converter, output 20K-100KHZ high-frequency AC power, add it to the LC series resonant circuit connected to the lamp to heat the filament, and at the same time generate a resonant high voltage on the capacitor, add it to both ends of the lamp tube, so that the lamp tube is powered by The "discharge" becomes the "conduction" state, and then enters the light emitting state. Compared wi...

Problems solved by technology

However, the existing energy-saving lamps also have the following disadvantages: firstly, energy-saving lamps are gas discharge light sources, without the characteristics of digital control, and cannot easily adjust the power; secondly, the current energy-saving lamps do not have the function of real-time monitoring of working status. Users cannot accurately know the status information of energy-saving lamps (such as temperature, current, remaining service life, etc.)

However, most of the existing lighting control systems are interconnected by wire, and the wiring and maintenance are cumbersome, inflexible, and poor in scalability. The energy-saving lamp lighting system connected by wireless communication can solve the above problems
