Problems solved by technology

However, electronic ballasts do not have this function, which greatly wastes energy or reduces the service life of lamps.
[0004] 2. Poor safety performance
When natural weather such as thunderstorms strikes, there is no protection function, and it is easy to be attacked by lightning, etc., and the product safety and reliability are poor
[0005] 3. The service life of the lamp is low
At present, there are various electronic ballasts that make the glow discharge process of the sodium lamp too long, and cannot enter the solitary discharge process in time, and the initial lamp current is relatively large, which makes the lamp electrode and the "wall black", further reducing the service life of the lamp.

Embodiment Construction

[0029] see figure 1 , The present invention provides an electronic ballast. The electronic ballast includes a dimming circuit, a microcontroller, and a frequency-sweeping ignition circuit; the dimming circuit and the frequency-sweeping ignition circuit are respectively connected to the microcontroller. Microprocessor control provides efficient and accurate processing, higher reliability, lower device component count, and smaller size.

[0030] Sweep frequency ignition can ensure stable ignition, basically eliminate lamp electrodes and "wall blackening", prolong lamp life.

[0031] The dimming circuit is a full-range analog or digital dimming, which saves significant energy. With an external sensor assembly, each lamp can automatically achieve dimming.

[0032] The dimming circuit includes a voltage input terminal, a dimming circuit signal input unit, a signal conversion unit, a control signal output unit and a load power adjustment unit; the voltage input terminal is sequenti...

Abstract

The invention relates to an electrical ballast which comprises: a dimming circuit, a microcontroller and a sweep frequency ignition circuit. The dimming circuit and the sweep frequency ignition circuit are respectively connected to the microcontroller. The invention provides the electrical ballast which can adjust equivalence brightness, possess a substantial energy saving effect, realize the sweep frequency ignition and can prolong a service life of a lamp. The electrical ballast is safe and reliable.

Description

technical field [0001] The invention belongs to the field of electricity and relates to a ballast, in particular to an electronic ballast for an intelligent high-voltage lamp. Background technique [0002] Electronic ballast is a kind of ballast, which is an electronic device that uses electronic technology to drive electric light sources to produce the required lighting. Corresponding to it is an inductive ballast (or ballast). More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and can even integrate electronic ballasts with lamp tubes. Go for starters alone. Electronic ballasts can also have more functions, such as improving or eliminating the flickering phenomenon of fluorescent lamps by increasing the current frequency or current waveform (such as becoming a square wave); it is also possible to use DC power for fluorescent lamps through the power inverter process. However, various electronic ballasts currently in use have the ...
