Abstract
The utility model relates to a fluorescent lamp tube apparatus, which comprises a lamp tube, a lamp tube fixed device which is connected with the lamp tube and makes the lamp tube wedged with a fluorescent lamp tube seat, a power input end which is installed on the lamp tube fixed device to input an electrical signal, and a resonating circuit which is electrically connected with the lamp tube and the power input end and arranged in the lamp tube fixed device to convert the electrical signal which is input from the power input end into a high-frequency approximation bowstring wave electrical signal which is needed for light emitting of the lamp tube.
Description
This case is a kind of fluorescent lamp, refers to contain the fluorescent lamp of a resonant circuit especially.
Adding electric ballast luxuriant with the fluorescent tube of reaching preferable illuminating effect and quality is the market mainstream, and the block schematic diagram of commonly using electric ballast as shown in Figure 1, and it comprises a straightening and filtering unit 11; One power inverter 12; One resonant circuit device 13; An and high-frequency drive device 14, it is sent the low-frequency ac power that Utilities Electric Co. provides through the direct current power that straightening and filtering unit 11 transfers low ripple to, then through power inverter 12 and acting on of high-frequency drive device 14 cause the square wave power of a higher-order of oscillation, after resonant circuit device 13 transfers the square wave power of high frequency to the high frequency electrical signal of the required approximate string ripple of fluorescent lamp 15.
Yet because electric ballast itself takes up space and often causes the puzzlement of Design of Luminaires, excessive volume causes it is integrated in difficulty in the light fixture, so how dwindling the ballast volume is an important topic, and fluorescent tube itself must exist the standard specification in order to combining with tube face, can be for utilizing so remain at remaining space, commonly use light fixture and the difficult disappearance of ballast integration and utilize this conception to improve, be the main purpose of this case development.
This case is a kind of light-emitting device, and it comprises: a fluorescent lamp; One power supply change-over device is electrically connected on this fluorescent lamp, in order to a low-frequency ac signal of telecommunication is changed into the square wave signal of telecommunication output of a higher-order of oscillation; And a resonant circuit device, being electrically connected on power supply change-over device, it is located in the entity of this fluorescent lamp, transfers the luminous required approximate string wave height of this fluorescent lamp signal of telecommunication frequently in order to the square wave signal of telecommunication with this higher-order of oscillation.
The preferably, this power supply change-over device comprises in this light-emitting device: a straightening and filtering unit, it sends the dc signal that this low-frequency ac signal of telecommunication transfers a low ripple to; One high-frequency drive device is in order to send a pulse wave signal; And a power inverter, be electrically connected on this straightening and filtering unit and high-frequency drive device, in order in response to this pulse wave signal,, the dc signal that will hang down ripple sends and transferring the square wave signal of telecommunication of a higher-order of oscillation to.
You Jiazhe, this power inverter is to be made of the half-bridge framework that comprises a pair of serial connection power transistor that is subjected to this pulse signal driving in this light-emitting device.
Another aspect of the invention is that it comprises about a kind of fluorescent lamp device: a fluorescent tube; One fluorescent-tube fixer is connected in fluorescent tube, and it is to be provided with making this fluorescent tube and a fluorescent lamp base to agree with; One power input end is installed in this fluorescent-tube fixer, in order to import a signal of telecommunication; And a resonant circuit, being electrically connected on this fluorescent tube and this power input end, it is positioned at this fluorescent-tube fixer, is the required high-frequency approximation string ripple signal of telecommunication of this lamp luminescence in order to the electrical signal conversion that this power input end is imported.
The preferably, this power input end is electrically connected the power supply change-over device of this signal of telecommunication of generation in this fluorescent lamp device, and wherein this signal of telecommunication is a higher-order of oscillation square wave signal of telecommunication.
This case must more be understood in depth in order to do getting one by following graphic and detailed description:
Fig. 1: the block schematic diagram of commonly using electric ballast and fluorescent tube;
Fig. 2: the block schematic diagram of this case one preferred embodiment;
Fig. 3: the schematic diagram of resonant circuit in this case one preferred embodiment;
Fig. 4: resonant circuit and fluorescent lamp are integrated in the schematic diagram of a housing in this case one preferred embodiment.
See also Fig. 2, it is this case one preferred embodiment block schematic diagram, wherein be arranged at this external power supply change-over device 21 of fluorescent lamp, by city electric contact L, N imports a low frequency ac, the straightening and filtering unit of being formed through rectification electronics 2111,2112 and filter capacitor 2113,2,114 211 give rectification and voltage multiplier and a low ripple direct current, drive and the square wave signal of telecommunication that carries out promptly becoming after power transistor 2121,2122 power inverters of being formed 212 that high frequency switches are handled the higher-order of oscillation is exported through the pulse signal that high-frequency drive device 213 sent again.Produce in the two ends of fluorescent lamp 23 and be arranged at the high-frequency current signal that resonant circuit device 22 in the fluorescent lamp transfers the higher-order of oscillation square wave signal of telecommunication to approximate string ripple again, wherein a preferred embodiment of resonant circuit sees also shown in Figure 3.
See also Fig. 4, this is integrated in the schematic diagram of a housing for resonant circuit in the present embodiment and fluorescent lamp, fluorescent tube 41 is connected with fluorescent-tube fixer 42, be provided with this fluorescent tube and a fluorescent lamp base are agreed with, power input end 43 is connected on this fluorescent-tube fixer 42, in order to importing the square wave signal of telecommunication of this higher-order of oscillation, and resonant circuit device 22 promptly is installed in this fluorescent-tube fixer 42.
This case will belong to the resonant circuit device 22 of electric ballast originally then be arranged at the body of fluorescent lamp, and then reach the effect of dwindling the electric ballast volume, and because fluorescent-tube fixer must exist the standard specification in order to combining with tube face, so remaining space that utilizes this fluorescent-tube fixer to remain, resonant circuit is incorporated in it, do not increase the fluorescent lamp actual volume, so just effectively improve the disappearance of commonly using light fixture and ballast integration difficulty, reach the main purpose of this case development.
This case must be thought and is to modify right neither taking off as Protector that attached claim is desired as all by person skilled in the art Shi Renshi craftsman.
