Abstract
The utility model discloses a round fluorescent lamp bulb which comprises a round glass bulb casing with fluorescent powder coating coated on the inner wall and two groups of filaments; the two groups of filaments are isolated from each other by a glass tube coated with fluorescent powder coating; the fluorescent lamp bulb is vacuumized when being encapsulated and filled with mercury steam and inert gas; and the bulb is started and lighted up through a rectifier. The round fluorescent lamp bulb has the advantages of simple manufacturing technique, large light-emitting area and energy conservation, and is similar to the traditional incandescent lamp in shape.
Description
Technical field
The utility model relates to a kind of illuminating lamp, particularly a kind of round fluorescent lamp bulb.
Background technology
Existing energy-saving fluorescent lamp is to develop from fluorescent tube, all be to be processed into single, double U pipe by elongated tubular, make many U or helical type lamp in order to increase light-emitting area, complex fabrication process, traditional incandescent lamp is because the problem of technology and technology can not be made round energy-saving fluorescent bulb, a spot of round energy-saving bulb is arranged on the market, also add the painted glass bubble and make, influence illumination effect at U type or helical type lamp.
Summary of the invention
The purpose of a kind of round fluorescent lamp bulb of the utility model is in order to solve above-mentioned the deficiencies in the prior art, provides that a kind of to have manufacturing process simple, and light-emitting area is big, similar traditional incandescent lamp shape, energy-conservation again round fluorescent lamp bulb.
In order to reach the purpose of a kind of round fluorescent lamp bulb of the utility model, realize by following technical solution: round fluorescent lamp bulb comprises that inwall scribbles round glass cell-shell, the cell-shell cover-plate glass of fluorescent coating, two groups of filaments, isolate by the glass tube that scribbles fluorescent coating between two groups of filaments, vacuumize during encapsulation, fill mercuryvapour and inert gas, light bulb by the rectifier build-up of luminance.Because glass tube isolated two groups of filaments, prolonged the distance between two groups of filaments, can effectively between two groups of filaments, load starting voltage, play gas in punctures, the ionization bubble, make bulb luminous, and can keep the luminous operating voltage afterwards of normal bulb.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Shown in Figure 1 is structural representation of the present utility model,
1. glass cell-shells among the figure, 2. cell-shell cover-plate glass, 3. glass tube separator, the 4. second filament group, the 5. first filament group.
Embodiment
The mist of oxygen, coal gas with compressed air delivery to the special equipment sealing machine of producing incandescent lamp, light the sealing machine shower nozzle, four filaments going up the fix tightly second filament group (4), the first filament group (5) at cell-shell cover-plate glass (2) by the duration and degree of heating of shower nozzle connect seal wire, weld the filament on (5) two seal wires of the firm first filament group.In the middle of the second filament group (4) and the first filament group (5), insert glass tube separator (3), and the sealing of the upper end of glass tube separator (3) fused on cell-shell cover-plate glass (2), inaccurate gas leakage, the lower end of glass tube separator (3) is unsettled, is diameter smaller or equal to glass tube separator (3) from glass cell-shell (1) lower end inwall distance.Two filaments of welding in parallel on (4) two seal wires of the second filament group are in the middle of two filaments one in front and one in back are enclosed in glass tube separator (3).At last with round glass cell-shell (1) and cell-shell cover-plate glass (2) encapsulation, round glass cell-shell (1) can be ellipse, cylinder, pear type, maximum gauge and glass tube separator (3) diameter vacuumizes, fills mercuryvapour and inert gas with 3: 1 the bests simultaneously in encapsulation.
Claims (3)
1. round fluorescent lamp bulb is characterized in that: by inwall scribble round glass cell-shell (1), cell-shell cover-plate glass (2), the second filament group (4), the first filament group (5) of fluorescent coating, the glass tube separator (3) that scribbles fluorescent coating is formed.
2. a kind of round fluorescent lamp bulb according to claim 1 is characterized in that: insert glass tube separator (3) in the middle of the second filament group (4) and the first filament group (5), and the upper end sealing of glass tube separator (3) is fused on cell-shell cover-plate glass (2).
3. a kind of round fluorescent lamp bulb according to claim 1 is characterized in that: two filaments of welding in parallel on (4) two seal wires of the second filament group, and in the middle of two filaments one in front and one in back are enclosed in glass tube separator (3).
