Description
Technical field
This is novel to relate to a kind of cold-cathode fluorescence lamp.
Background technology
Chinese patent application numbers 200310109366.4 discloses a kind of spiral type cold-cathode fluorescence lamp, comprises cell-shell, fluorescent tube, tube cathode, seal wire, driver and shell thereof, lamp holder and line.
Above-mentioned the deficiencies in the prior art part is: above-mentioned cold cathode lamp can only keep a brightness when using, and the working temperature of electrode is higher, so not anti-flicker is impacted, can not frequent starting, cold and hot cataclysm influence is bigger, and electrode is easily oxidized, causes the useful life of fluorescent tube shorter.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, be suitable for significantly improving the fluorescent tube cold-cathode fluorescence lamp in useful life.
In order to solve the problems of the technologies described above, the utility model provides a kind of cold-cathode fluorescence lamp, comprising: the connection housing c between lamp holder a and the fluorescent tube b; Be provided with the light modulation drive circuit in the described connection housing c, be with cell-shell d on the fluorescent tube b; Adjacent lamp tube sealing-in place b1 is provided with in the fluorescent tube b: negative electrode d, electrode cable f, glass tube e and glass stem g; Negative electrode d is electrically connected with the top of electrode cable f, and negative electrode d and electrode cable f be located among the glass tube e, and glass stem g is located at the lower end of glass tube e, glass stem g and described fluorescent tube sealing-in place b1 sealing-in, and electrode cable f extends the lower end this fluorescent tube sealing-in place b1.
Further, be provided with liquid mercury in the described glass tube e.Further, but described negative electrode d is aluminum pipe, oxygen-free copper pipe or valve pipe.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) lamp luminescence principle: add required high-frequency and high-voltage by giving between the two end electrodes of fluorescent tube, with gas breakdown ionization in the fluorescent tube, cause discharge.At this moment, the ionization that is excited of a large amount of mercury atoms produces the 253.7nm ultraviolet ray, and the high frequency fluorescent material on the tube wall is subjected to ultraviolet radiation and sends visible light.Glass tube in the utility model fluorescent tube is as protective cover, and glass stem is that glass tube and electrode play the support effect, with the convenient electrode of placing; (2) but electrode of the present utility model adopts pure aluminum tube or oxygen-free copper pipe or valve pipe, its working temperature is lower than conventional fluorescent lamps, thus anti-especially flicker impact, but frequent starting, cold and hot cataclysm influence is less, oxidation is less, can guarantee that fluorescent tube has long useful life; And adopt the fluorescent tube of this electrode, cooperate light adjusting circuit of the present utility model to use, double-helical fluorescent tube can a circle one be punctuated bright and is not glimmered when light modulation, and dimming behavior is better.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the contour structures schematic diagram of the cold-cathode fluorescence lamp among the embodiment;
Fig. 2 is the part section structure chart of the cold-cathode fluorescence lamp among the embodiment.
Embodiment
See Fig. 1-2, the cold-cathode fluorescence lamp of present embodiment, it comprises: lamp holder a, fluorescent tube b and be located at lamp holder a and fluorescent tube b between connection housing c, connect in the housing c and be provided with the light modulation drive circuit.The cylindrical double helix of the main body of cold cathode fluorescent lamp of the present utility model, in order to protect cold cathode fluorescent lamp, fluorescent tube b is provided with cell-shell d.
Adjacent lamp tube sealing-in place b1 is provided with in the fluorescent tube b: negative electrode d, electrode cable f, glass tube e and glass stem g; Negative electrode d is electrically connected with the top of electrode cable f, and negative electrode d and electrode cable f be located among the glass tube e, and glass stem g is located at the lower end of glass tube e, glass stem g and described fluorescent tube sealing-in place b1 sealing-in, and electrode cable f extends the lower end this fluorescent tube sealing-in place b1.
Be provided with liquid mercury in the glass tube (e), mercury atom is excited under tyco electronics, produces the 253.7nm ultraviolet ray, and ultraviolet ray excited fluorescent material sends visible light.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
