CN2137820Y - Combined filament - Google Patents

Abstract

The utility model relates to a combined filament, composed of two filaments combined together, wherein, a public end and the other two ends points are respectively provided with one conducting wire and the two conducting wires are respectively connected with three tube corners. Thus, the two filaments have three operation modes of separateness, series connection and parallel connection. Thus, the combined filament has a long service life and can be made into a light regulation style bulb. The combined filament can be arranged in products, like a picture tube, an oscilloscope tube, a fluorescent tube, a vacuum tube, various bulbs, lamp bulbs, etc. The light relation style bulb can be arranged in a family, an organ, a cinema and a theater, a ballroom and a vehicle.

Description

Combined filament

The utility model relates to a kind of Combined filament.

Filament is the heart of devices such as picture tube, oscilloscope tube, fluorescent tube, electron tube, various bulb and small electric bulb, because of the life-span of filament shorter, often cause above-mentioned device premature damage.

The purpose of this utility model is exactly will design a kind of life-span to be longer than the Combined filament that has filament now.

Combined filament of the present utility model is made up of filament (1) and (2), can conducting between filament (1) and (2) (implication of conducting comprises following three kinds of situations: one is that a filament does not cut off and is divided into two filaments; Two is that two filaments directly are connected together, middle no conductor; Three is that two filaments are done media by conductor and linked together), the common port (6) of filament (1) and (2), end points (3) and (9), by three leads (7), (4), (10), link to each other with three limbs (8), (5), (11) respectively.Because of there are three terminals the Combined filament outside, thereby make lamp (1) and (2) have separately, connect and three kinds of working methods in parallel.The specification of filament (1) and (2) can be different.

The Combined filament of the utility model design has following advantage:

1, the life-span is long

Because filament (1) and (2) can work independently, after filament (1) aging or blowing, re-use filament (2), so the life-span of Combined filament is longer than existing filament, improved the life-span of devices such as picture tube indirectly.

2, can be made into the light modulation bulb.

Because filament (1) and (2) have separately, connect and three kinds of working methods in parallel, have dimming function so the bulb of this kind filament is installed.This kind desk lamp with dimmer switch bubble structure is simple, and is easy to use, can be installed on the places such as family, office, cinema, dance hall and the vehicles.In the place of easy-maintaining not this kind light modulation bulb is installed, and its filament is worked in series, its life-span will be longer, thereby can reduce maintenance times.

Fig. 1 is the Combined filament structural representation of the utility model design.

Claims (1)

1, a kind of filament is combined by filament (1) and (2), it is characterized in that between filament (1) and (2) can conducting, and the common port (6) of filament (1) and (2), end points (3) and (9), by three leads (7), (4), (10), link to each other with three limbs (8), (5), (11) respectively.
