The utility model discloses under the effect of the main silk of its electrode and the inseparable orderly combination of internal thread, improved stability, increased the cross-sectional area to a great extent, improved the bearing capacity to electric current, voltage, and then strengthened the radiant energy of lamp, prolonged the life of middling pressure lamp.

Description

High-efficient middling pressure lamp

Technical Field

The utility model relates to a light-emitting equipment technical field specifically is a high-efficient middling pressure lamp.

Background

The electrode is a high-temperature resistant metal wire in a medium-pressure lamp, is mostly a thin tungsten wire, also has iridium or an alloy thereof, and can directly emit light and generate heat when electrified, or emit electrons and ultraviolet rays, form a high-energy electric field, generate high-energy rays and the like to excite a fluorescent substance, a rare gas or form plasma to generate visible light. The conventional electrode is mostly formed by double-helix winding, and has the defects of limited large current bearing capacity, low radiation energy and short service life. Therefore, how to overcome the above defects becomes a problem to be solved urgently by the company.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model discloses a high-efficient medium voltage lamp.

The utility model provides a high-efficient middling pressure lamp, which comprises an electrode, the electrode includes the main silk, the main silk outer wall connection has at least three rotational symmetry's heliciform internal thread.

The utility model discloses under the effect of the main silk of its electrode and the inseparable orderly combination of internal thread, improved stability, increased the cross-sectional area to a great extent, improved the bearing capacity to electric current, voltage, and then strengthened the radiant energy of lamp, prolonged the life of middling pressure lamp.

Further, the high-efficiency medium-pressure lamp further comprises a spiral outer wire wrapping the inner wire. The outer wire is used for fixing the inner wire and the main wire, so that the structure is more stable, the cross section area is increased, and the current and voltage bearing capacity is further improved.

Further, the inner wire spirals in the opposite direction to the outer wire. So set up, make whole structure more firm.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a front view of the present invention;

fig. 2 is a top view of the present invention, in which three internal wires are provided;

fig. 3 is a top view of the present invention, wherein four internal threads are provided;

in the figure: 1. main filaments; 2. internal thread; 3. and (4) external threads.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model relates to a high-efficient middling pressure lamp, including the electrode, the electrode includes main silk 1, and 1 outer wall connection of main silk has the heliciform internal thread 2 of three rotational symmetry, and 2 outer wall parcel of internal thread have outer silk 3, and outer silk 3 is used for fixed internal thread 2 and main silk 1 to under the effect of

internal thread

2 and 3 spiral opposite directions of outer silk, overall structure is more firm.

The utility model discloses under the effect of the main silk 1 of its electrode, interior silk 2 and the inseparable orderly combination of outer silk 3, improved stability, increased the cross-sectional area to a great extent, improved the bearing capacity to electric current, voltage, and then strengthened the radiant energy of lamp, prolonged the life of middling pressure lamp.

Example two: compared with the first embodiment, the differences are as follows: as shown in fig. 3, four rotationally symmetric spiral inner wires 2 are connected to the outer wall of the main wire 1.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
