Description

FLUORESCENT TUBE WITH INTERNAL STARTER SUMMARY OF THE INVENTION The fluorescent tube with internal starter is disclosed by an innovative common structure of a fluorescent tube installed with a internal starter to obtain the following advantages: The starter seat and the assembly manpower cost for the tube set can be saved.

o As the tube and the starter are in a common structure to be replaced together, the homogeneity of performance status between the tube and the starter is maintained synchronous, whereby the life and efficiency of the tube set is benefited altogether.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an embodying example of the invention illustrating a long cylinder type tube.

Figure 2 is an embodying example of the invention illustrating that the starter as in figure 1 is installed inside the tube.

DETAILED DESCRIPTION OF THE INVENTION The fluorescent tube with internal starter is disclosed by an innovative common structure of a fluorescent tube installed with a internal starter to obtain the following advantages: The starter seat and the assembly manpower cost for the tube set can be saved.

As the tube and the starter are in a common structure to be replaced together, the homogeneity of performance status between the tube and the starter is maintained synchronous, whereby the life and efficiency of the tube set is benefited altogether.

The above said homogeneity means the synchronism of the performance status between the tube and the starter, thereof since the starter is internally installed, both of the tube and the starter are in a common structure, when the tube is out of order, the starter will also be near the failing age, and similarly, when the starter is out of order, the tube will not be good, while for the conventional separated design types, usually only the failed one of the two is replaced, thereof as is well known, that the degraded starter will accelerate the tube to failure, and the degraded tube will also accelerate the starter to failure, thereby at the condition of alternated replacements, the inferior homogeneity of the performance status may cause the tube and starter to experience higher frequency of failures and shortened lives.

Figure 1 is an embodying example of the Fluorescent tube with internal starter illustrating a low cylinder type tube, wherein it is mainly comprised of the following: A tube 100: It is made of transparent insulator material such as glass, and is filled with mercury vapor (or other fluorescent gas), whereof its two ends are respectively installed with filament 102 and shade 112, and through the conducting pin 110 connected with the filament 102 to accept the power input, wherein a starter 104 is installed within one of the shades 112 and is series connected between one of the filaments 102 and the conducting pins 110, thereof the two ends of the whole tube set 100 are respectively provided with a pair of conducting pins 110 and a shade 112, thereof if the shades 112 are constituted by conductors, then a insulator clip 111 is provided between the conducting pins 110 and the shade 112; The filament conducting wire 121: It is series installed between the two filaments 102 through the starter 104, whereof the conducting wire 121 can be installed inside or outside of the tube, or it can be connected to the external conducting wire through the conducting pins 110 to connect the two filaments.

A starter 104: It includes the starter types of the various solid state switches or electromechanical switches, delay activating switches, or electromechanical thermal activating switches, or Gas thermal activated switches for activating the fluorescent tube.

The above said tube is incorporated in the tube sets with series installed stabilizer (Including the conventional inductance type or electronic type) to provide the full functions for the fluorescent tube operation.

The design can be also modified to pre-connect the conducting pins 110 leading to the starter 104 and the filament 102 at the other end of the tube 100 by the conducting wire 121, thereby to allow only one pair of conducting pin 110 at both ends for power input.

The design can be further modified to install the starter inside the tube; Figure 2 is an embodying example illustrating that the starter is installed inside the tube, which is mainly comprised of the following: A tube 100: It is made of transparent insulator material such as glass, and is filled with mercury vapor (or other fluorescent gas), whereof its two ends are respectively installed with shade 112, and the inside of tube is installed with filaments 102 and starter 104, and power input is accepted at the conducting pin 110 connected to the filaments 102, wherein the starter 104 is series installed between the filaments 102 and conducting pins 110 inside the tube 100, and each end of the tube 100 is respectively installed with a pair of conducting pins 110 and shade 112, thereof if the shade 112 is a conductor, then a insulator clip 111 is provided between the conducting pins 110 and shade 112.

The filament conducting wire 121: It is series installed between the two filaments 102 through the starter 104, whereof the conducting wire 121 can be installed inside or outside of the tube, or it can be connected to the external conducting wire through the conducting pins 110 to connect the two filaments.

A starter 104: It includes the starter types of the various solid state switches or electromechanical switches, delay activating switches, or electromechanical thermal activating switches, or Gas thermal activated switches for activating the fluorescent tube.

The design can be also modified to pre-connect the conducting pins 110 leading to the starter 104 and the filament 102 at the other end of the tube 100 by the conducting wire 121, thereby to allow only one pair of conducting pin 110 at both ends for power input.

As is summarized above, the innovative design discloses a fluorescent tube with internal starter, whereby the fluorescent tube and the starter can be maintained at a good operating status for long term usage, thereby to save cost of the manufacture, starter seat and the assembly manpower, thereof as it is original, innovative and practical, we have surveyed and found no similar claims of prior arts, your legal approval of this claim is greatly appreciated.
