Abstract
The utility model relates to a small power fluorescent tube and a lamp which is made of the fluorescent tube. The small power fluorescent lamp is provided with auxiliary electrodes in two cathodes of a traditional fluorescent lamp (comprises a hot cathode lamp and a cold cathode lamp), and starting voltage is reduced. Meanwhile, as long as the utility model adopts a resistance capacitor as a ballast, the utility model can quickly start under commercial power voltage. The work of the utility model is stable, and the cost of the fluorescent lamp is reduced. Compared with the original fluorescent lamp, the lifetime of the utility model is extended by more than two times.
Description
The light fixture that the utility model relates to a kind of small-power fluorescent tube and utilizes this fluorescent tube to make.
Fluorescent lamp is subjected to popular favor owing to luminous efficiency is high, but fluorescent lamp must have ballast to work.For the following fluorescent lamp of small-power fluorescent lamp, particularly 5W, adopt the relative energy consumption of Inductive ballast big, efficient is low, and adopts electric ballast, and its cost is again than higher; Adopt the little capacitor of power consumption to make ballast, though price is low, power consumption is little, volume is little, but its fatal shortcoming is that pulse current is big, waveform difference, starting resistor and to refire voltage low, this not only has a strong impact on the life-span of fluorescent tube, and can make fluorescent tube flicker and extinguish, the long fluorescent tube of going up point of two cathode distance also can start and work.For above-mentioned reasons, just be difficult to see the following compact fluorescent lamp of 5W in the common low-light level lamp.
The light fixture that the purpose of this utility model provides a kind of small-power (3W is following) fluorescent tube and utilizes this fluorescent tube to make, it only needs resistance capacitance as ballast, under line voltage, starts fast, working stability, the life-span is long.
In order to achieve the above object, we respectively acquire an auxiliary electrode at two negative electrode places of fluorescent lamp (comprising hot cathode lamp and cold-cathode lamp) respectively, auxiliary electrode apart from negative electrode 1 to 3mm, the fluorescent tube external diameter is 5 to 12mm, distance between two negative electrodes is 10 to 80mm, and the shell of fluorescent tube can be made straight tube shape or single U-shaped.
Through improving later small-power fluorescent tube like this, can directly carry out ballast by resistance capacitance, draw the auxiliary electrode that is connected to the fluorescent tube other end by a resistance respectively at two negative electrode places, arbitrary therein then negative electrode is directly received civil power after connecting the ballast that resistance capacitance forms, another negative electrode is then directly received civil power, becomes that a kind of cost is low, the small-power fluorescent lighting fixture of working stability.Connect after the power supply, by the effect of current-limiting resistance electric capacity, build-up of luminance discharge in advance excites the gas build-up of luminance in the fluorescent tube between negative electrode and auxiliary electrode, lights fluorescent tube.
In general, being directly proportional between the starting resistor of fluorescent tube and the size that refires voltage and negative electrode apart from size, and be inversely proportional to fluorescent tube internal diameter size size, so the distance L control at fluorescent tube two interpolars is controlled under the situation of L/ Φ＜9 less than 90mm, fluorescent tube internal diameter Φ, has improved the stability of fluorescent lamp greatly; In addition owing to increased auxiliary electrode, can greatly reduce starting resistor, make fluorescent tube can be under lower line voltage fast starting and steady operation, owing to having saved Inductive ballast cost and power consumption are reduced greatly simultaneously, the life-span is longer more than one times than like product.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structure chart of small-power fluorescent tube.
Fig. 2 is small-power fluorescent lighting fixture circuit theory diagrams.
Among Fig. 1,1 is the fluorescent tube shell; 2 is negative electrode, identical with the conventional fluorescent fluorescent tube, can be cold cathode or hot cathode, and two negative electrodes are at a distance of 10 to 80mm; 3 is auxiliary electrode, and available nickel-containing alloys material is made.
Among Fig. 2, two negative electrodes 2 draw on the auxiliary electrode 3 that is connected to the other end by resistance R 2, R3 respectively, and wherein a negative electrode connects civil power after being connected in series by resistance R 1 and capacitor C 1, and capacitor C 1 two ends also connect a resistance R 4, and another negative electrode directly connects civil power.
