Abstract

A convection heat-dissipation type taper single-spiral energy-saving lamp bubble comprises an energy-saving lamp body, a lamp-bulb outer cover, a lamp-bulb base and a drive circuit in the lamp-bulb base. Two groups of lead wires of the energy-saving lamp body are connected with corresponding electrodes of the drive circuit. The lamp-bulb outer cover is covered outside of the energy-saving lamp body. An opening end of the lamp-bulb outer cover is connected with the lamp-bulb base in order to sealing the energy-saving lamp body. The energy-saving lamp body comprises a tube body. Cathode filaments are respectively sealed in sealing ends of the tube body. Lead wires of the cathode filaments are mounted outside of the sealing ends of the tube body. Bubbling is mounted on a position of the tube body near the sealing end. By adopting the above technology measures, a large-tube pressure problem of large-caliber and long-tube energy-saving lamps is solved, so that the lamp temperature is reduced and service life of the lamps is prolonged; a problem of a very large size of a double-spiral structure of large-power energy-saving lamps is solved and a lamp-bulb heat-dissipation problem is solved.

Description

Convection heat-dissipation conic single-screw energy-saving bulb

Technical field

The utility model relates to a kind of electricity-saving lamp, particularly relates to a kind of convection heat-dissipation conic single-screw energy-saving bulb.

Background technology

Since fluorescent lamp came out, the use of room lighting light source, especially electricity-saving lamp that becomes main flow was more and more extensive.In recent years, the electricity-saving lamp technology is towards Large Diameter Pipeline, big-length, high-power future development.From production and processing and drive circuit design angle, its difficulty is not large especially, still, because the developing direction of electricity-saving lamp technology has brought the fluorescent tube pipe to press the problem high, that temperature is high.Existing but double helical energy-saving lamp, in its high-power specification, shared volume is too large.In addition, for easy to use, electricity-saving lamp will cooperate bulb to produce together sale.Energy-saving bulb comprises the drive circuit in electricity-saving lamp body, outer bulb envelope, light bulb base and the base.In the time of use, as ordinary incandescent lamp, directly light bulb base is installed on the lamp holder and gets final product.But for the high-power energy saving bulb, its caloric value is large, can not satisfy the heat radiation requirement by the heat exchange of outer bulb envelope.

Summary of the invention

In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of convection heat-dissipation conic single-screw energy-saving bulb, and concrete technical scheme is:

Drive circuit in a kind of convection heat-dissipation conic single-screw energy-saving bulb, electricity-saving lamp body, outer bulb envelope, light bulb base and light bulb base; Two groups of seal wires of electricity-saving lamp body are connected with the respective electrode of drive circuit; Outer bulb envelope covers on electricity-saving lamp, and this is external, and the openend of outer bulb envelope is connected with light bulb base, seals the electricity-saving lamp body;

Described electricity-saving lamp body comprises lamp tube body, and sealing respectively in the sealing end of lamp tube body has cathode filament, and the seal wire of cathode filament is outside the lamp tube body sealing end.

The position at the close sealing end place of described lamp tube body is provided with bubbling;

Described lamp tube body is single coil configuration; The shape of this helical structure: establish a cone; Be provided with bending in lamp tube body; The limit, first sealing end place of bending is on the axis of described cone; The position of bending is at the place, summit of cone; On the outer wall screw of the described cone in edge, tail sealing end place of bending;

Described outer bulb envelope is cone shape; Bottom surface at cone has pilot hole, and this pilot hole consists of the openend of described outer bulb envelope; Vertex position at cone has air inlet, and the outer rim in the bottom surface of cone has a plurality of air outlets, and each air outlet is evenly distributed along the outer rim of the bottom surface of cone.

Compared with prior art, the utility model is taked above-mentioned technical measures, the pipe that had both solved Large Diameter Pipeline, long modulator tube electricity-saving lamp pipe is pressed large problem, the temperature of fluorescent tube is decreased, prolonged lamp tube service life, solve again the too large problem of double-stranded volume of high-power energy-saving lamp tube, in addition, also solved the bulb heat radiation problem.In addition, the light-emitting area of this bulb is taper, downwards the better effects if of irradiation.
