Abstract

The utility model discloses a fluorescent lamp bulb which is composed of a lamp bulb outer shell (1), fluorescent powder (2) coated on the inner wall, a low voltage mercury glow-discharge tube (3), a resonant capacitor (4), a lamp cap (5), etc. After the lamp bulb is communicated with high frequency power supply outputted by an electronic ballast which is matched, glow-discharge is generated in the low voltage mercury glow-discharge tube (3), ultraviolet rays of 253.7 nm are generated, the ultraviolet rays are transmitted, which can activate the fluorescent powder (2) on the inner wall of the glass shell (1) of the fluorescent lamp bulb to emit fluorescent light, and the lamp bulb emits light. The utility model has the advantages of high light efficiency, energy saving, and good color rendering property. The utility model has all the advantages of a cold light source. The usage is convenient like an incandescent lamp bulb. Compared with a fluorescent lamp and the incandescent lamp, the service life is longer.

Description

Fluorescent lamp bulb

The utility model relates to a kind of bulb, particularly the low-pressure mercury fluorescent lamp bulb.

Public bulb series products has following four kinds: (one), incandescent lamp bulb.It is by U.S. inventor Edison invention, lean on to be that electric energy is heated to filament incandescent and luminous.This incandescent lamp bulb light efficiency is very low, and power consumption is big, and color rendering is poor, and the life-span is short.(2), compact energy-saving fluorescent lamp.It is at the glass tube two ends of bending filament electrode to be housed, and is filled with mercury and inert gas in the glass tube, scribbles three primary colors fluorescent powder at the glass tube inwall; After fluorescent tube adds operating voltage, glow discharge takes place in the fluorescent tube, the ultraviolet ray that produces 253.7nm makes fluorescent material send fluorescence, and lamp is just bright.Compact energy-saving fluorescent lamp color rendering is good, energy-conservation, but glow discharge directly contacts with fluorescent material in the fluorescent tube, thereby make fluorescent material be subjected to the pollution of cathodic sputtering thing and foreign gas, make its easy blackout, especially filament electrode place in two ends turns black severely, the fluorescent material premature aging, life-span does not reach ideal, also exists the very crisp easily broken shortcoming of damaging of glass tube because of bending.(3), fluorescent tube, this fluorescent tube and compact energy-saving fluorescent lamp principle of luminosity are identical, not only with there is same shortcoming, can not do very shortly but also exist fluorescent tube, use inconvenient shortcoming.(4), arc discharge lamp.This class lamp has high-pressure mercury lamp, sodium vapor lamp etc.They all are to adopt the principle of arc discharge luminous, exist into height jointly.Cost an arm and a leg, the life-span is short, and distribute heat is big, and light is dazzling not soft, a lot of unconformable shortcomings of occasion.

The purpose of this utility model be to provide on a kind of performance can with compact energy-saving fluorescent lamp, the same light efficiency height of tubular type fluorescent lamp, energy-conservation, color rendering is good, and light is soft, and distribute heat is little, cost is not very high, but fluorescent material can not turn black and be difficult for aging, and the life-span is long, and has and the much the same profile of incandescent lamp bulb, easy to use, not breakable relatively low-pressure mercury fluorescent lamp bulb.

The purpose of this utility model is achieved in that a resonance is housed starts electric capacity in lamp holder, its lamp holder bottom links together with the glass bulb of fluorescent lamp bulb, scribble fluorescent material on the inwall of glass bulb, the low-pressure mercury glow discharge tube of making of the uviol pipe is being adorned at position placed in the middle in glass bulb.(general electric ballast output has 4 terminals when the high frequency electric source that the electric ballast of the utility model fluorescent lamp bulb and coupling is exported is connected, wherein two started the resonant capacitance outputs are empty not to be connect, with lamp socket on all the other two terminations, with the utility model fluorescent lamp bulb this lamp socket of packing into) after, the low-pressure mercury glow discharge tube two ends filament pre-heating of making of uviol in the fluorescent lamp bulb, there is higher resonance potential at the two ends of the resonant capacitance in the lamp holder simultaneously, glow discharge takes place thereby the low-pressure mercury glow discharge tube is started, the ultraviolet ray that produces 253.7nm sees through on the glimmering powder that the uviol pipe directive glass bulb inwall of the present utility model of low-pressure mercury glow discharge tube is coated with and fluorescence excitation, and fluorescent lamp bulb is just bright.

The utility model fluorescent lamp bulb has four advantages and is well suited for people's needing of illumination of living.This fluorescent lamp bulb of one belongs to cold light source, so distribute heat is not high; Its two this fluorescent lamp bulb principle of luminosity belongs to the operation principle of low-pressure mercury fluorescent lamp, so its light efficiency height, energy-conservation, light is soft, and price is suitable; Glow discharge in its three this fluorescent lamp bulb is closed in the low-pressure mercury glow discharge tube, and its glow-discharge cathode sputter thing and foreign gas etc. can not polluted fluorescent material, have avoided fluorescent material blackening and premature ageing, so the fluorescent lamp bulb life-span is long; Its four this fluorescent lamp bulb has the glass bulb of a similar incandescent lamp bulb, thereby makes it easy to use, is protecting enervated low-pressure mercury glow discharge tube to make it to be difficult for crashing simultaneously, so solid relatively reliable.

Further specify the concrete implementation issue of this utility model below in conjunction with accompanying drawing.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is an embodiment of the present utility model.

Among the figure: 1, glass bulb, 2, fluorescent material, 3, the low pressure glow discharge pipe, 4, resonance starts electric capacity, 5, lamp holder.

The glass bulb (1) of the utility model low-pressure mercury fluorescent lamp bulb should use the light transmittance height and be fabricated to good to the strong glass of the ultraviolet reflection ability of 253.7nm; It is good that the fluorescent material (2) that glass bulb (1) inwall is coated with should use triphosphor Fluorescent Powder; The glass tube of low-pressure mercury glow discharge tube (3) should use the ultraviolet ability of transmission 253.7nm strong, and the weak uviol of the ultraviolet ability of transmission 158.0nm is made, its shape can curve U type, many U-shapeds, spirality and M, W shape etc. as required and all can, make U-shaped in the present embodiment, the manufacturing of the mercury that charges in the pipe and inert gas and filament electrode is identical with manufactured materials, the technology of public fluorescent tube, no specific (special) requirements; Resonant capacitance (4) should be selected for use withstand voltage more than 630 volts, capacity should be generally thousands of picofarads according to the operating frequency decision of the electric ballast of selecting for use, selects the electric ballast of 35KHZ in the present embodiment for use, adapted resonant capacitance (4) is withstand voltage to be 630 volts, and capacity is 2700 picofarads; Lamp holder (5) can adopt the screw socket or the socket lamp holder of standard; select GB1406-89 standard E27/25 type lamp holder in the present embodiment for use; be evacuated in the bulb or charge into and can improve light-emitting phosphor efficient and the gas of protecting fluorescent material, evacuated mode was made the utility model fluorescent lamp bulb in present embodiment adopted and will steep.
