Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, an intelligent general-purpose dimmer includes a power module 1, a controller 2, a mains interface 11, a load interface 12, a dimming circuit 3, a voltage zero-crossing detection circuit 4, a current zero-crossing detection circuit 5, and a short circuit control Circuit 6, overload acquisition circuit 7, load detection circuit 8 and communication module 9. The mains interface 11 is used to connect 220V alternating current, as the input of the intelligent universal dimmer in this embodiment, including live wire and neutral wire. The load interface 12 is used to connect various dimmable lamp loads. The load interface 12 is the output interface of the intelligent universal dimmer in this embodiment, and the output is the alternating current after phase cutting, including live wire and neutral wire. The load lamp is connected ...

Abstract

The invention discloses an intelligent universal light modulator which comprises a main supply interface, a load interface, a light modulation circuit, a current zero crossing point detection circuit, a voltage zero crossing point detection circuit and a controller. The light modulation circuit is sued for controlling breakover time and interval within each mains supply period through the controller so as to achieve regulation on a load device. The current zero crossing point detection circuit is used for acquiring and inputting a current zero crossing point signal on a mains supply live wire to the controller. The voltage zero crossing point detection circuit is used for acquiring and inputting a voltage zero crossing point signal into the controller. The controller is used for analyzing the current zero crossing point signal and the voltage zero crossing point signal and judging whether a device connected to the load interface is a capacitive device or a sensitive device, controlling the light modulation circuit in a leading edge phase-cut mode when the device connected to the load interface is the sensitive device and controlling the light modulation circuit in a lagging edge phase-cut mode when the device connected to the load interface is the capacitive device.

Description

technical field [0001] The present invention relates to dimmers, in particular to digital dimmers. Background technique [0002] Since human beings realize that we must do everything possible to save energy and reduce emissions in order to solve the urgent problem of atmospheric warming, how to reduce lighting power consumption has become an important issue on the agenda. Because lighting electricity accounts for 20% of the total energy consumption. If the lamps adopt a dimmable mode, and sample various new types of lamps with higher lighting efficiency, such as halogen lamps and LED lamps, more energy will be saved in lighting. [0003] Traditional lighting only has switch control, without any fault detection and control, brightness adjustment, remote communication control and other functions. With the development of science, technology and economy, the requirements of energy saving and emission reduction and building intelligence, dimmers have become an indispensable dev...
