Abstract
The utility model of a cold cathode fluorescent lamp mainly a strip lamp (1) coated with rare earth three primary colors phosphor powder, a cold cathode filament (2) and a cold cathode outlet (3). The cold cathode filament is directly conducted and excited by the high frequency high voltage output by an electronic ballast (4) and the filament needs no heating, so the utility model is energy-saving and high-efficient and the service life can reach above 15000 hours. The utility model has single outgoing wire and is reliable and easy for installation and belongs to new generation of green light source.
Description
Technical field:
Electric light source
Background technology:
Now the fluorescent lamp that uses adopts the hot cathode emitting electrons, promptly with electric current elder generation heated cathode, makes its emitting electrons, the ultra-violet radiation fluorescence excitation bisque of discharge generation and luminous.This hot cathode filament in tube starting and luminescence process, has heater current to pass through all the time.The heat that heater current causes is bigger, to making the aging easily fracture of filament, influences fluorescent tube useful life.
Summary of the invention:
The utility model adopts cold-cathode emitting electron, lamp is in starter and luminescence process, itself does not have heater current filament, all the time allow filament be in cold state, because need not to consider the ability of filament loaded current, so can be with the suitable overstriking of filament, so both increased the mechanical strength of filament, increased the surface area of filament again, filament electron emission ability (work function) just greatly strengthens, if use rare-earth trichromatic fluorescent powder, long-life of fluorescent tube like this, highly reliable, advantages such as big brightness have just been realized.
Description of drawings:
(1) scribbles the tube wall of three primary colors fluorescent powder for the fluorescent tube inboard among the figure, and (2) are helical form cold cathode filament; (3) be the cold cathode lead-out wire.(4) be matching used special electric ballast.Embodiment: connect civil power 220V power supply, electric ballast output high-frequency high-voltage, directly put on the cold cathode of lamp tube ends, cold cathode two ends instantaneous high pressure, low pressure discharge in fluorescent tube produces UV-activated tube wall fluorescent material and luminous.
Cold cathode is the very long-service life fluorescent tube, is applicable to the place that some spaces are higher, as places such as airport, station, subway, auditorium, gymnasium, classrooms, needn't often change fluorescent tube.
Cold cathode fluorescent lamp is long especially useful life, reliable in quality, and energy-conservation, caloric value is low, and wiring simple and easy (unipods lamp) is installed, and with the supporting use of electric ballast, belongs to the new generation of green light source.
Claims (3)
1. lighting device cathode fluorescent tube, it is characterized in that: negative electrode is a helical heater, two ends lead-in wire short circuit single line is drawn.
2. cathode fluorescent tube according to claim 1, it is characterized in that: filament can be standard type, also suitably overstriking.
3. cathode fluorescent tube according to claim 1 is characterized in that: its shape can be thread, and helical form also can be tubular.
