Abstract
The utility model relates to a lighting lamp, in particular to a spiral compound cathode gas discharge lamp with cold end structure, which is characterized in that based on original spiral lamp structure, one group or more than one group of cold cathode and hot cathode are connected in parallel at the filament installation, which are combined into a compound cathode; an L-shaped cold end is protruded out of the pipe wall on the upper part of the lamp burner; the cold end is connected with the intracavity of the lamp, and deviated from the discharge channel of the discharge tube; a linear opening is made in the center of the cold cathode. The lighting lamp can efficiently decrease the ignition voltage of discharge tube, accelerate the escape of mercury atom and increase the service life of gas discharge lamp; the mercury gas pressure in discharge lamp can be regulated by the cold end, which can increase the luminous efficiency of lamp, and the traditional high voltage sodium lamp and mercury lamp can be completely replaced in road lighting lamp. The lighting lamp has the advantages of low energy consumption, good luminous efficiency and significant energy saving.
Description
Technical field
The utility model relates to lighting, and particularly profile adopts the spirality glass lamp, and inside pipe wall scribbles the spirality composite cathode gaseous discharge lamp of the band cold end structure of rare-earth trichromatic fluorescent powder.
Background technology
Traditional in the past high-pressure sodium lamp, high-pressure mercury lamp consume energy big and light efficiency develops the color all relatively poor, low mercury is pressed high-power gas charging lamp, just as being contained in the light fixture of a sealing, along with temperature sharply raises, the ultraviolet spectral line can produce serious skew, cause that starting voltage is higher, influence useful life, light efficiency is not given full play to yet.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of spirality composite cathode gaseous discharge lamp with cold end structure is provided.
The technical solution of the utility model is the spirality composite cathode gaseous discharge lamp of band cold end structure, include helical lamp, coated has fluorescent material in the fluorescent tube, lamp tube ends is stretched out socket, the socket inner chamber is equipped with filament and connects with electrode, constitute hot cathode, it is characterized in that said filament installation place is parallel with a group or more cold cathode and hot cathode composition composite cathode; L shaped cold junction is stretched out at tube wall place on fluorescent tube top, and this L shaped cold junction can be divided into the unidirectional or two-way fluorescent tube inner chamber that both had been connected in, and deviates from the discharge channel of discharge tube again.
Said composite cathode is an integral type or split type, straight line middle opening on it.
The utility model advantage is 1, this composite cathode adopts new construction and new material, reduces the starting voltage of discharge tube effectively, quickens the effusion of mercury atom, improves the life-span of gaseous discharge lamp; 2, the mercury vapour that adopts the spirality gaseous discharge lamp of band cold end structure to regulate and control in the discharge lamp by cold junction is pressed, thereby significantly improves the light efficiency of lamp; 3, by above innovation, make low mercury press high-power gas charging lamp aspect road lighting, can replace power consumption and all relatively poor light sources of light efficiency colour developing such as high-pressure sodium lamp, high-pressure mercury lamp fully, have powerful energy-saving potential.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the another kind of structural representation of composite cathode.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2,1-helical lamp, 2-socket, 3-cold junction, 4-composite cathode.As shown, helical lamp 1 its inwall coated has fluorescent material, and lamp tube ends is stretched out socket 2, and socket 2 inner chambers are equipped with filament and connect with electrode and constitute hot cathode.The innovation part is that the cold cathode and the hot cathode that are parallel with a group or more in the filament installation place are formed composite cathode.Tube wall place on socket 2 tops is extended with L shaped cold junction, and this cold junction is connected in the fluorescent tube inner chamber on the one hand, and the aspect deviates from the discharge channel of discharge tube again in addition.The composition form of cold cathode can be the straight line middle opening or make
Shape.It is incense coil shape, straw hat shape, mushroom-shaped that spirality socket 2 can be made profile.Cold junction 3 is made unidirectional or two-way.Composite cathode can be made integral type or split type.Split-type structural as shown in Figure 2.
Claims (2)
1. be with the spirality composite cathode gaseous discharge lamp of cold end structure, include helical lamp, coated has fluorescent material in the fluorescent tube, lamp tube ends is stretched out socket, the socket inner chamber is equipped with filament and connects with electrode, constitute hot cathode, it is characterized in that said filament installation place is parallel with a group or more cold cathode and hot cathode composition composite cathode; L shaped cold junction is stretched out at tube wall place on fluorescent tube top, and this L shaped cold junction can be divided into the unidirectional or two-way fluorescent tube inner chamber that both had been connected in, and deviates from the discharge channel of discharge tube again.
2. according to the spirality composite cathode gaseous discharge lamp of the said band cold end structure of claim 1, it is characterized in that said composite cathode is an integral type or split type, straight line middle opening on it.
