Abstract
The power factor (PF) of novel fluorescence lamp driver approaches 1, and cold cathode directly startup is suitable for various new and old, useless fluorescent tubes illumination uses.This circuit does not have semiconductor element, does not have auxiliary switch yet, and it can start fluorescent tube under low temperature low-voltage condition.It is that power saving, fluorescent tube are long service time that the resident uses the benefit of novel fluorescence lamp driver illumination.This circuit also can be used for not having the usefulness of filament open column shape fluorescent tube illumination.
Description
The invention relates to a kind of illuminating line, fluorescent lighting circuit particularly, this novel circuit for fluorescent lamp can overcome the shortcoming of traditional type circuit for fluorescent lamp, not only economizes on electricity if use this circuit, and actual life that can also prolonging lamp tube.
It is very difficult that the traditional type circuit for fluorescent lamp starts under low temperature and low-voltage condition, the high-frequency current radiation meeting in starter when work influences some radio system, if one of fluorescent tube or two filament come off and just can't continue to light and make full use of it and refire.Also the someone uses the various illuminating lines that rekindle waste fluorescent lamp at present, is not complex circuit, is exactly that extra switch or electronic component are many, the high trouble of using of cost.The starter of traditional type circuit for fluorescent lamp also has three problems affect fluorescent tube operate as normal and life-span, punctures such as starter poor efficiency, contact adhesion, starter inner capacitor.
The purpose of this invention is to provide a kind of energy-conservation, fluorescent tube actual life long, without any need for the fluorescent lighting circuit of extra switch and semiconductor-assisted element.
This novel fluorescence lamp driver is made up of shake capacitor C, four end ballast B fluorescent tube R and mains switch K of a Harmonic as shown in the figure.With that group coil of ballast of capacitors in series, be actuating coil, the big electric current of actuating coil produces and starts flux of magnetic induction to another group actuating coil of ballast when switch closure.Consequent induction high voltage directly starts fluorescent tube R, whole line work mode is similar with traditional circuit for fluorescent lamp after fluorescent tube is lighted, but capacitive branch is connected in parallel on the electrical network, it and ballast actuating coil Hui Lu Harmonic shake under the frequency of electrical network, remedy the phase angle of perception, make power factor (PF) approach 1, energy-conservation reason that Here it is.Fluorescent tube is that cold cathode directly starts, thus can instantaneous starting, even also can start in low temperature low-voltage occasion, and it is little to start loss, and the life-span of fluorescent tube is not subjected to the influence of the number of starts yet.Because circuit for fluorescent lamp startup form of the present invention is a cold cathode, thus the old fluorescent tube that cathode emission material exhausts, even the useless fluorescent tube that two filament all comes off can both rekindle on the novel fluorescence lamp driver.
If the novel florescent lamp line applications in the popular edition invention not only can improve the power factor (PF) of electrical network, the factory that makes fluorescent tube can also produce the fluorescent tube of no filament open column shape negative electrode, has simplified technology, has reduced cost.It is that power saving, fluorescent tube are long service time that the resident uses the benefit of novel fluorescence lamp driver.The novel fluorescence lamp driver can adapt under the low temperature low-voltage and starts, and entry condition is better than the conventional fluorescent lamp driver.
Claims (4)
1, by a capacitor, the novel florescent lamp illuminating line that one four end ballast and fluorescent tube are formed, the characteristics of circuit be can be under the low temperature low-voltage instantaneous starting, the electrode of fluorescent tube has only two circuit power factors after the startup to approach 1.
2, the capacitor in the power 1. is connected with the actuating coil of ballast, equivalent inductance De Harmonic Xia mains frequency of the decision of its capacitance it and ballast value of shaking.
3, four end ballast actuating coil lines in the power 1. directly are coarser than actuating coil.
4, the fluorescent tube in the power 1. has only the fluorescent tube of two electrodes for no filament.
