Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.Fig. 1 is the structural representation of an embodiment of large power cold cathode fluorescent lamp of the present utility model.It includes at least one multiterminal cathode fluorescent tube 1, is the example of one three end spirality cathode fluorescent tube shown in Fig. 1.The straight tube 2 of spiral central authorities is the thicker fluorescent tube of a diameter, and for example diameter is 3 to 40mm.There are at least one electrode 3 and lead-out wire 4 thereof in its lower end.Its upper end links to each other with two helical lamps 5,6, and the other end of fluorescent tube 5,6 respectively has at least one electrode 7,8 and lead-out wire 9,10 thereof.11 is at least one driver among Fig. 1, and 12 is the shell of driver, and the input of driver 13 links to each other with electric connector (being a lamp holder 14 shown in Fig. 1) through going between, and is used to connect external power supply.The output of driver 11 4,9,10 links to each other with each electrode of fluorescent tube 1 through going between, and is used to light fluorescent tube.Fluorescent tube 1 (comprising straight tube 2 and helical lampl 5,6) is fixed on the top board 15 of drive enclosure 12.Be enhance mechanical strength, on the top board 15 ledge 18 can be arranged.16 transparent, diffusion or coloured printing opacity cell-shell, the shape of cell-shell can be the different shape of common bulb, is made by glass or plastics.
The central straight tube 2 of described three end cathode fluorescent tubes 1 and two helical lamps 5,6 interconnect, constitute a vacuum chamber, be filled with discharging substances such as argon, neon, helium, mercury or xenon in the chamber, each fluorescent tube is made by glass or quartz glass, and luminescent material 17 is arranged on its inwall.After adding suitable operating voltage between each electrode, promptly produce Discharge illuminating between each electrode.
But the luminescent material 17 on the ultraviolet ray exciter lamp tube wall of discharge generation to be to produce the light of required look, when the light source of needs ultraviolet ray or this coloured light of gas discharge, and also can be on the tube wall without luminescent material.Described two helical lamps 5,6 can be same-handed diameter and identical pitch, also can be different screw diameters and pitch inequality, shown among Fig. 15,6.
The electrode 3 of central authorities' straight tube 2 can be used for respectively or simultaneously with electrode 7,8 discharges of helical lampl 5,6, at this moment, the sparking electrode spacing is about half of helical lampl 5,6 length overalls, thus its play bright voltage and operating voltage low, can be used to make more powerful cold-cathode fluorescence lamp.
The electrode 3 of central authorities' straight tube 2 also can be used to accelerate the bright speed that rises of lamp, uses electrode 7,8 discharges to helical lampl 5,6 of high voltage and electric current when promptly beginning, and after lamp reached certain brightness, electrode 3 open circuits produced normally luminous by electrode 7 and 8.
As shown in Figure 1, two helical lampls 5,6 are the fluorescent tube of different screw diameters, and two helical layer shape fluorescent tubes are promptly arranged, thereby can be made into the cold cathode fluorescent lamp of small-volume large-power.
