Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence; a kind of thick tube wall, high mechanical properties, spiral type cold-cathode fluorescence lamp that volume is little are provided; it need not to add in addition the fluorescent tube supporter and comes support luminous tube; also need not with cell-shell protection, thereby can be made into the thick lamp tube wall spiral type cold-cathode fluorescence lamp of mechanical strength height, no fluorescent tube supporter, no cell-shell, luminous efficiency height, fluorescent tube good heat dissipation, lamp long working life.It includes at least one spiral type cathode fluorescent tube, the driver of a fluorescent tube and shell thereof, an electric connector, the input of described driver links to each other with external power with electric connector through lead-in wire, its output links to each other with the electrode of cathode fluorescent tube through lead-in wire, connects external power and can light fluorescent tube; Described fluorescent tube is fixed on the top of described drive enclosure, the shell of described driver is interconnected to a whole lamp to described spiral type cathode fluorescent tube and electric connector, described spiral type cathode fluorescent tube is the cathode fluorescent tube of thick tube wall, and its tube wall thickness is the 19%-45% of fluorescent tube external diameter; Thereby can be made into high mechanical properties and need not the spiral type cold-cathode fluorescence lamp of fluorescent tube supporter, also need not to add the fragile originally cold cathode fluorescent lamp of cell-shell protection, reduced the cost of lamp.Simultaneously, select suitable fluorescent tube thickness, fluorescent tube internal diameter and power of lamp tube, make the discharge gas in the fluorescent tube work in optimum temperature, for example 60-90C of cold-cathode fluorescence lamp, thereby can obtain best luminous efficiency.
The cathode fluorescent tube of described thick tube wall is the fluorescent tube of blue outside line, white light or other coloured light, and described fluorescent tube is made by soft glass, Bohemian glass or vitaglass, for transparent, diffusion or painted; Its helical shape is pagoda shape, cylindricality, round end cylindricality, candle, sphere shape, pyriform, almost spherical, conical in shape.
The cathode fluorescent tube of described thick tube wall is difform single-screw or double helical form fluorescent tube, on its electrode getter is arranged.
Described driver is for can be the interchange of input or the direct voltage AC/AC or the DC/AC converter that are transformed into the high-frequency high-voltage that is suitable for cathode fluorescent tube work, and for example 1KC-800KC, hundreds of are to several kilovolts high-frequency electrical.
The pillar that has fixed lamp tube to use on the top of described driver has an astragal striped or corner angle to increase the structure of frictional force, so that the loading and unloading of lamp around the driver top.
The glue sealing and fixing is all used in the bearing of described fluorescent tube and pillar, drive enclosure and its junction, top, electric connector and drive enclosure junction.
Described electric connector is the various lamp holders as the existing lamp of the lamp screw base of different size and structure, socket lamp holder, plug-type lamp holder.
The utility model compared with prior art, have that volume is little, mechanical strength is high, vibration resistance, shock-resistant, need not the advantages such as cold-cathode fluorescence lamp that fluorescent tube supporter, no cell-shell, luminous efficiency height, fluorescent tube good heat dissipation, lamp long working life, cost are low, can be used for making high or low power
