CN87206581U - Long life bulb - Google Patents

Abstract

The utility model discloses a new long life bulb, which adds a set of filament on the prior lamp and additionally solders a set of contact points on the top of the lamp cap. Two sets of the filaments can be the identical power or the different power. When one set of the filaments wears out, the other set can be used by transferring the contact. The utility model has the advantages of tunable power and long service life, which reduces the consumption of the raw materials and the power.

Description

Long life bulb

Bulb is a kind of ordinary appliances device.Its structure all is one group of filament since the own bulb history, pair of contact, a power.After filament blow, other component parts of bulb---glass shell, stamen post, lamp holder are all abandoned as refuse.

The design's purpose is to improve the utilance of glass shell, stamen post, lamp holder, prolongs bulb service time, and makes its adjustable power.

Design is: increase by one group of filament on the stamen post of original bulb, increase pair of contact and the supporting use of newly-increased filament at the lamp holder top.Fig. 1 is the structure of slot-like bulb, by filament (1), and glass shell (2), stamen post (3), lamp holder (4), contact (5) are formed.Behind one group of filament blow, as long as lamp holder turn 90 degrees angle and another group contacting, this group filament can continue to use.Fig. 2 is a screw socket shape bulb structure, by filament (1), and glass shell (2), stamen post (3), lamp holder (4), ambroin sleeve pipe (5), lamp holder iron sheet opening (6), wire filament (7) is formed.Only need the ambroin sleeve pipe (7) on the lamp holder is taken off after one group of disintegration of filament, another group filament energising can continue to use.If two filaments are made different power, transfer contact as required during use, bulb can enter two kinds of different capacity user modes.

Compare this product with existing bulb and have following advantage:

1. for same bulb, glass shell, the stamen post, lamp holder to be used once, increases operation rate one times;

2. do not change the technological process of original production bulb, do not increase new equipment, can make output increase about one times;

3. a bulb has two kinds of power, implements simple, easy accommodating user;

4. the raw material and the energy resource consumption of producing glass shell, stamen post, lamp holder have been saved.

Claims (3)

1, a kind of Life-prolonging electric bulb, it is by filament [1], glass shell [2], stamen post [3], lamp holder [4] is formed, and it is characterized in that:

(1) goes up one group of filament of many welderings for the slot-like bulb at stamen post [3], go up one group of contact of many welderings, the supporting use in this filament and contact after the energising at lamp holder [4];

(2) go up one group of filament of many welderings for screw socket shape bulb at stamen post [3], go up one group of many weldering and the matching used contacts of newly-increased filament at lamp holder [4], this contact is by ambroin sleeve pipe [6], iron sheet opening [7], and wire filament [8] is formed.

2, Life-prolonging electric bulb as claimed in claim 1 is characterized in that two groups of filament wattages are identical.

3, Life-prolonging electric bulb as claimed in claim 1 is characterized in that two groups of filament wattages are different.
