Description

Fluorescent tube

Technical field

The utility model is the lamp tube structure of light source about a kind of fluorescent tube especially in regard to a kind of light that sends with CCFL.

Background technology

The light fixture that is used for office or household's ceiling at present, because irradiation space broad, therefore the consumer continues to use traditional elongated fluorescent tube mostly, the intensity of illumination of this kind elongated fluorescent tube is higher than the another kind of employed LED light fixture of consumer that is, and the external form of LED light fixture is different with existing daylight light fixture with the connected mode of its lamp socket and civil power, if it is also higher to install the spent cost of LED light fixture, though therefore traditional elongated daylight lamp life is shorter, consider to still have most of persons light modulation pipe another day based on price.

And present CCFL (CCFL, cold-cathode fluorescent lamp), its principle of luminosity and daylight light fixture are similar, the lamp socket specification is identical with the daylight light fixture, can general same city electric connection socket, and selling price is about the LED light fixture half, service life is longer than daylight light fixture, become a big hot topic first-selection of present light fixture, the principle of luminosity of CCFL and daylight light fixture exist together mutually for: by the ionized inert gas of fluorescent tube inside, mercury and electron synchrotron are in fluorescent tube inner space collision excitation, when lamp tube electrode applies high voltage electric field, the mercury molecule has been produced ultraviolet ray by electronic impact, is coated on after fluorescer on the inner tubal wall absorbs this ultraviolet ray, can send visible light; And the different place of two light fixtures is: CCFL does not adopt the mode that adds thermoelectron to allow electron excitation clash into, but utilizes the string wave high-voltage electric field action behind the high frequency switching resonance to discharge by electronic impact.

By as seen aforementioned, CCFL is to utilize the mode of high-frequency and high-voltage to reach luminous purpose, therefore its security regulations are also than the strictness of general daylight light fixture, at present existing is the light fixture of light source with the CCFL, as Fig. 7 and shown in Figure 8, its structure has a hollow elongated lampshade 90, its lampshade 90 two ends are respectively equipped with an adapter 901, the inner space of lampshade 90 and the axial location that is positioned at central authorities are separated with a plate 91, side at plate 91 is provided with a pcb board, be loaded with CCFL module 92 on this pcb board, for example: transformer (PZT), electric capacity etc., cold-cathode lamp tube module 92 can interconnect by the adapter 901 at pcb board and lampshade 90 two ends, and cold-cathode lamp tube module 92 is sealed in the inner space of lampshade 90, and the high pressure of avoiding its transformer to produce leaks and causes danger; Opposite side at plate 91 is provided with cold cathode luminous tube 93, and the end of cold cathode luminous tube 93 can interconnect with the adapter 901 of lampshade 90, is electrically connected to reach with 92 generations of cold-cathode lamp tube module;

Because plate 91 is arranged at the axial location of lampshade 90 central interior, therefore cold cathode luminous tube 93 goes out only half of surplus lampshade 90 surface areas of optical range, thereby reduce the luminous intensity that of CCFL, make the life-span advantage longer of CCFL be gone out the more weak shortcoming covering of luminous intensity, and then reduce the wish that the consumer chooses CCFL by it than daylight light fixture.
