Abstract
The utility model discloses an energy-saving lamp tube with a cold end, which comprises a single cathode lamp tube and a double cathode lamp tube and is characterized in that the cold end is a dead-end tube, and a pipe orifice of the dead-end tube is connected with the lamp tube and communicated with the lamp tube. The pipe diameter of the dead-end tube is 5mm at least, and the length of the dead-end tube is 20mm at least.
Description
Technical field:
The utility model relates to lighting device, is specifically related to high-power electronic energy-saving lamp.
Background technology:
Electricity-saving lamp has outstanding power savings and soft comfortable photoenvironment because of it, obtained promoting the use of widely, along with improving constantly of people's living standard, and energy supply anxiety factors such as (electricity price height), electricity-saving lamp more becomes people's first-selected illuminating product.But the electricity-saving lamp major part of extensively being promoted the use of at present is low power, be suitable for the illumination of family, office space, and high-power energy-saving lamp causes useful life short because some technical problems fail to obtain fine solution, has limited its production and promotes the use of.As everyone knows, the principle of electricity-saving lamp is by the ultraviolet ray excited light-emitting phosphor of the specific wavelength that produces after the mercury atoms, mercury gas is in discharge process, because wick environment temperature height, the tungsten filament evaporation is fast, easily causes tungsten filament fusing, perhaps causes lamp to dodge, perhaps cause the lamp tube end blackout, these all will influence the useful life of high-power energy-saving lamp.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of power saving fluorescent lamps that has cold junction, can effectively reduce the tungsten filament evaporation rate, overcomes the defectives such as product weak point in useful life that cause soon because of the tungsten filament evaporation.
The utility model is achieved through the following technical solutions:
The power saving fluorescent lamps that has cold junction comprises single negative electrode fluorescent tube, the twin cathode fluorescent tube, and characteristics are that described cold junction is a blind pipe, the mouth of pipe of blind pipe is connected in fluorescent tube, and is communicated with fluorescent tube.
The further improvement project of the utility model is that blind pipe is communicated in the medium position of fluorescent tube total length.The caliber of blind pipe is at least 5mm, and the length of blind pipe is at least 20mm.
Less than the minimum dimension of above-mentioned caliber and length requirement, bad to the regulating effect of fluorescent tube.
The utlity model has following advantage:
Therefore the utility model can effectively reduce the tungsten filament evaporation rate owing to the medium position at the fluorescent tube total length is provided with blind pipe, overcomes the defectives such as product weak point in useful life that cause soon because of the tungsten filament evaporation.
Description of drawings:
Fig. 1 is the utility model schematic diagram.
Embodiment:
As shown in Figure 1, have the power saving fluorescent lamps of cold junction, comprise single negative electrode fluorescent tube, the twin cathode fluorescent tube.Described cold junction is a blind pipe 2, and blind pipe 2 mouths of pipe are connected in fluorescent tube 1, and is communicated with fluorescent tube 1.
Still as shown in Figure 1, blind pipe 2 is arranged at the medium position of fluorescent tube 1 total length.The caliber of blind pipe 2 is 10mm, and its length is 40mm most.Blind pipe 2 internal face fluorescent coatings are consistent with fluorescent tube 1 internal face fluorescent coating.
