Description

General daylight reinforced device

The utility model relates to a kind of universal fluorescent lamp intensive.

Fluorescent lamp is since coming out the thirties, because advantages such as its optical efficiency height, the life-span is long, light is soft, become the main light source of room lighting, because fluorescent lamp system " negative resistance gas discharge " element, must just can light and operate as normal with annex combinations such as ballast and starters, want reasons such as consumed power and reactive loss owing to annex itself, though caused daylight light fixture optical efficiency high, electrical efficiency is lower, and shortcoming that failure rate high strict to supply power voltage.

Desirable fluorescent lamp should have that power consumption is low, efficient is high, the life-span is long, failure rate is low, be suitable for the wide combination property of voltage range, for a long time, people have done a large amount of improvements to the daylight light fixture, existing some fluorescent lamp improves the appearance of circuit, as direct current light, electronic ballast, the series connection of lampet pipe etc., but these improve the raising of only having emphasized certain performance mostly, and ignored some other performance, more harm than good, loses more than gain, and is difficult to reach the ideal effect in the practicality.

The purpose of this utility model is to overcome existing weak point in the above-mentioned prior art and provides a kind of rational in infrastructure, start rapidly, the working voltage wide ranges, failure rate is low, can improve the fluorescent lamp power factor (PF), prolonging lamp tube useful life, and can be applicable to the universal fluorescent lamp intensive of single tube, two-tube, three pipes.

The purpose of this utility model realizes by following measure: this fluorescent lamp intensive is made up of capacitor C and inductance coil L, and the quantity of inductance coil is identical with the quantity of connecing fluorescent tube, can be a coil, two coils, three coils.

In the utility model, the capacity of capacitor C is 8 microfarads, its withstand voltage: more than the direct current 500V, used coil all is contained on the iron core.

The utility model compared with prior art, has following advantage: simple in structure, applied widely, can be used for single tube, two-tube, in the fluorescent lamp circuit of three pipes, good low voltage starting performance is arranged, economize on electricity 15%～40%(is to use power of lamp tube different and different with number), reduce line current 30%(single tube), 45%(is two-tube), 60%(three pipes), good constant current characteristic is arranged, illuminance is not influenced by voltage fluctuation, prolonging lamp tube service life, therefore no consumable accessory has reduced failure rate, reduces the caloric value 20%(single tube of light fixture), 40%(is two-tube), 60%(three pipes).

The drawing of accompanying drawing is described as follows:

Circuit diagram when Fig. 1 is connected to single tube daylight for the utility model.

Circuit diagram when Fig. 2 is connected to daylight double for the utility model.

Circuit diagram when Fig. 3 is connected to three pipe fluorescent lamps for the utility model.

The utility model is done to describe in detail below in conjunction with (accompanying drawing) embodiment:

Embodiment 1: with the light fixture with 40 watts of fluorescent tubes is example.

As shown in Figure 1: capacitor C and an inductance coil L1 that this intensive is 8 microfarads by an appearance value form, the number of turn of coil L1 is 1400 circles, be wound on the degree of lip-rounding iron core, wherein the end of coil L1 links to each other with the filament 5 of fluorescent tube 3, the other end links to each other with filament 6, the other end of filament 5 connects power supply by ballast 2, and the other end of filament 6 connects other end power supply by capacitor C.After energized, electric current becomes one to exchange the closed-loop path through switch 1, ballast 2, filament 5, inductance coil L1 and filament 6, capacitor C, and inductance coil L1 two ends produce high voltage and puncture the fluorescent tube gas discharge and light fluorescent tube because of resonance at this moment.The lamp tube ends resonance potential is reduced to the pressure drop numerical value (110V) of single tube fluorescent tube and operate as normal automatically then.

Embodiment 2: with the light fixture with two 40 watts of fluorescent tubes is example.

As shown in Figure 2: one group of coil L2 of intensive is serially connected in two fluorescent tubes, 3,4 one ends by in two groups of filaments, 6,8 series circuits of being formed, coil L1 is serially connected between two groups of filaments of the two fluorescent tube other ends 5,7, coil L1, L2 are wound on the same degree of lip-rounding iron core, L1 is 1400 circles, L2 is 180 circles, the other end of filament 5 connects power supply by switch 1, ballast 2, and the other end of filament 7 connects other end power supply by capacitor C.After the energising, by the series resonant circuit of filament, for filament 5,7 provides preheat curent, coil L2 provides preheat curent for filament 6,8, and after filament was heated to the energy emitting electrons, under the resonance potential effect, fluorescent tube is starter gradually, discharges until gas breakdown.The lamp tube ends resonance potential is promptly reduced to pressure drop numerical value (200V～220V) and the operate as normal of two fluorescent tubes series connection automatically then.

Embodiment 3: with the light fixture with three 40 watts of fluorescent tubes is example.

As shown in Figure 3: coil L2 is serially connected in two fluorescent tubes, 3,4 one ends by in two groups of filaments, 6,8 series circuits of being formed, in the series circuit that the other end filament 7 that coil L3 is serially connected in fluorescent tube 4 and an end filament 9 of fluorescent tube 11 are formed.Another group filament 5 one end connecting coil L1 of fluorescent tube 3, an end connect power supply by switch 1, ballast 2.The other end of one end connecting coil L1 of the other end filament 10 of fluorescent tube 11, the other end of filament 10 connects another root power line by capacitor C.Coil L1, L2, L3 all are wound on the same degree of lip-rounding iron core, and L1 is 1400 circles, and L2, L3 are 180 circles.After the energising, resonant circuit by filament 5 series coil L1 and filament 10, produce resonance potential and provide preheat curent for filament 5,10, filament 6,8 is supplied with preheat curent by L2, coil L3 provides preheat curent for filament 7,9, after all filaments were heated to the triggering electronics simultaneously, under the resonance potential effect, fluorescent tube build-up of luminance gradually discharged until gas breakdown.The resonance potential of each lamp tube ends is promptly reduced to pressure drop numerical value (300V～330V) and the operate as normal of three fluorescent tubes series connection automatically then.
