Abstract

The utility model relates to a novel two-filament bulb. A lamp cap is fixedly connected with a glass bulb shell body 2, and a glass column 4 is arranged in the bulb shell body 2. The utility model has the key point that the inner part of the bulb is provided with three conducting wires which are two fire wires 8 and one zero line 3 and are all arranged in the glass column 4. One section of a lamp filament 5 is connected with one fire wire 8 and a common zero line 3, and the other section of lamp filament 5 is connected with the other root fire wire 5 and the common zero line 3. The lower end of the lamp cap is provided with two insertion poles 6 which are connected with the two fire wires 8. The zero line 3 is connected with an iron shell of the lamp cap 2. The utility model is matched with a specific socket, the utility model can adjust the illuminating brightness of the bulb according to different requirements. The utility model has the advantages of energy saving and low cost.

Description

Two filament lamp

It is illuminating that the utility model belongs to general life, refers to illuminating bulb especially.

The power of the incandescent light bulb that general lighting is at present used is all fixed, that is to say and to adjust power to adapt to different illumination purposes, also be unfavorable for saves energy, the method of adjusting bulb power at present is to utilize variable resistor or controllable silicon basically, change resistance etc., reach the purpose of adjusting bulb power, variable resistor or controllable silicon etc. all are mounted on the Bulb holder of table lamp, but for the economic also relatively backward at present rural area of China, this desk lamp still is somewhat expensive, the a lot of rural areas of China at present or two rooms use an incandescent lamp bulb, as on two room wall, digging a hole, bulb is put in the hole, given two room illumination, therefore bulb being made improvements at present China's wide geographic area still has huge economic benefit.

The utility model just provides a kind of lighting power that can change bulb as required, favourable energy-conservation novel bilux bulb.

Realize that the purpose of this utility model in technical scheme is: fixedly connected glass bulb housing 2 on the lamp holder 1, one glass column 4 is arranged in the bulb shell 2, it is characterized in that having in the bulb three leads, two live wires 8 and a zero line 3 are all put in glass column 4, and a segment filament 5 links to each other with common zero line 3 with a live wire 8, another section silk links to each other with common zero line 3 with another root live wire 5, be equipped with two inserting columns 6 in the lower end of lamp holder, and link to each other with two live wires 8, zero line 3 links to each other with the iron-clad of lamp holder 2.

Have 7, two inserting columns 6 of an annular ditch groove to be positioned at following 0.7 centimetre of center line on described lamp holder 2, two posts are at a distance of 1.4 centimetres.

For the use that matches with above-mentioned bulb, two jacks are arranged, in its socket at a distance of 1.4 centimetres, apart from 0.7 centimetre in center line, the inserting column 6 of bulb can insert in the jack of socket, and the outstanding steel disc in three centres is arranged in the socket, annular ditch groove 7 on protuberance and the lamp holder adapts, and can clamp bulb, be equipped with on the socket one can about the handgrip stirred, i.e. switch, Xiang Yiduan stirs, and connects a live wire 8 and common zero line, dials to the other end, then connect another root live wire of bulb and common zero line.

Owing to be connected to the filament of different capacity between two live wires of the present utility model and the zero line, then can adjust the brightness of illumination of bulb as required, have energy-saving advantages, and cheap, very suitable to vast rural area and economic backward area.

Fig. 1 is a structural representation of the present utility model.
