Abstract
The utility model provides an energy-saving lamp tube with a cool end, and comprises double helical lamp tube bodies and two pins, wherein the double helical lamp tube body are serially connected side by side, and the two pins are arranged at the bottom of the lamp tube body; and at least a cool end perpendicular to the main axis of the lamp tube and pointing to the outer side of the lamp tube is arranged at the top of the lamp tube. By adopting the energy-saving lamp with the cool end, the size of the lamp tube is small, the maximum of the actual light efficiency value of the lamp tube under proper mercury vapor concentration is close to the theoretical value; moreover, the lamp tube has the advantages of simple manufacture process and low cost.
Description
Technical field
The utility model relates to a kind of power saving fluorescent lamps with cold junction.
Background technology
The helical form exposed conduit has the double helix shape exposed conduit main body and two pins of parallel serial connection, does not have on the exposed conduit main body or only is provided with a cold junction that forms by frothing, and cold junction is positioned at exposed conduit main body top end face center; Or subsidiary two above cold junctions are arranged, wherein the additional cold junction except that main cold junction is positioned at outside the fluorescent tube; Or in the inboard new cold junction (patent No.: ZL02255145.X) of blast pipe butt joint formation of using of helical lampl.The power saving fluorescent lamps that does not have or only have a cold junction can't make existing fluorescent tube mercury vapor inside concentration reach optimum range, makes that the actual light efficiency value and the theoretical value gap of existing fluorescent tube are big, and actual light is logical, the light efficiency value is not high; The subsidiary power saving fluorescent lamps that two and above cold junction are arranged, except that main cold junction, additional cold junction is positioned at the fluorescent tube outside can increase the fluorescent tube outside dimension, influences outward appearance and packaging process; And can increase manufacturing process in the inboard method of using the blast pipe butt joint to form new cold junction of helical lampl, strengthen cost, and fracture is damaged easily in fluorescent material coating clamping operation, thereby strengthens the fluorescent tube manufacturing cost and influence fluorescent tube production qualification rate.
The utility model content
The utility model provides a kind of power saving fluorescent lamps with cold junction, and it is big that it has solved in the background technology the actual light efficiency value and the theoretical value gap of fluorescent tube, and actual light is logical, the light efficiency value is not high, and manufacturing process's complexity, cost height, shortcoming that the production qualification rate is low.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of power saving fluorescent lamps with cold junction, it comprises: one has walk abreast double helix shape fluorescent tube main body that is connected in series and two pins that are located at the fluorescent tube bottom part body,
In one preferred embodiment, be provided with the cold junction that a vertical fluorescent tube main shaft points to the fluorescent tube outside at least at fluorescent tube main body top.
In one preferred embodiment, be provided with the cold junction that two vertical fluorescent tube main shafts point to the fluorescent tube outside at fluorescent tube main body top.
In one preferred embodiment, this two cold junction is axially symmetrical with respect to the fluorescent tube main body axis.
In one preferred embodiment, this cold junction and fluorescent tube main body are that the one heating is shaped.
Power saving fluorescent lamps of the present utility model is compared with background technology, has the following advantages: be provided with the cold junction that a vertical fluorescent tube main shaft points to the fluorescent tube outside at least at fluorescent tube main body top 1..Since this cold junction be not located at the fluorescent tube top vertically towards, the fluorescent tube size is less, the fluorescent tube size that is provided with additional cold junction than the fluorescent tube main body outside is also little, and the inner mercury vapour concentration of fluorescent tube comes balance by cold junction, and the actual light efficiency value of fluorescent tube is to greatest extent near theoretical value under appropriate mercury vapour concentration; 2. be provided with the cold junction that two vertical fluorescent tube main shafts point to the fluorescent tube outside at fluorescent tube main body top, this two cold junction is axially symmetrical with respect to the fluorescent tube main body axis, makes that the profile of fluorescent tube is more attractive in appearance; 3. cold junction and fluorescent tube main body are that the one heating is shaped, and make that the manufacturing process of fluorescent tube is simple, and cost reduces.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the front schematic view of an embodiment of the present utility model.
Fig. 3 is the structural representation of another embodiment of the present utility model.
Fig. 4 is the front schematic view of another embodiment of the present utility model.
Description of reference numerals:
Fluorescent tube main body-100; Luminous tube pin-110; One cold junction-120; Another cold junction-130.
Embodiment
See also Fig. 1 to Fig. 4, they have illustrated the power saving fluorescent lamps that preferred embodiment of the present utility model provided.
In conjunction with Fig. 1, Fig. 2, it comprises fluorescent tube main body 100, luminous tube pin 110, a cold junction 120.
As shown in Figure 1, be provided with the cold junction 120 of a level at fluorescent tube main body 100 tops towards the fluorescent tube outside.
As shown in Figure 3, be provided with the cold junction 120 and 130 of two levels at fluorescent tube main body 100 tops, and this two cold junction is axially symmetrical with respect to the fluorescent tube main body axis towards the fluorescent tube outside.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
