    Abstract: In a fixation structure for fixing a lamp on a printed circuit board (PCB), a connection end of the lamp is received within a connection hole of the PCB and a sleeve having approximately cone shape is disposed between the lamp and the PCB. When the connection end of the lamp is continuously inserted into the connection hole of the PCB, a contact area between the connection end and the connection hole is increased, thereby effectively enhancing a contact-and-on performance of the lamp and the PCB. Sleeves may be located on lamps leads or alternatively placed in the connection hole of the PCB.

    Abstract: An improved winding base structure of a transformer is assembled by combining a primary-side winding base and a secondary-side winding base. The selection of the material of the primary-side winding base and the secondary-side winding base is dependant on the compression-resistant capability because the primary-side input and the secondary-side output of the transformer bear different voltages. The outside of the assembled winding base is disposed with grooves in which the wires are wound, and the center of the winding base is disposed with a through hole for an iron core to be put therein to form a transformer. The sectional winding base of the subject application is characterized in that the primary-side winding base is made of lower compression-resistant material and the secondary-side winding base is made of higher compression-resistant material. Therefore the production cost of the winding base is reduced.

    Abstract: A double frequency signal generator to which a synchronization signal having a duty cycle of 1% to 999% is inputted. The synchronization signal is used for triggering of a switching component at positive and negative edges to generate a triangular-wave signal. An average of voltages of the triangular-wave signal is acquired and compared with the triangular-wave signal at a comparator to generate a square-wave having a duty cycle of 50%. Then, the square-wave signal is used for triggering at positive and negative edges to generate a double frequency signal. As such, the high cost issue and the limitation of a square-wave input signal occurred in the prior art may be efficiently overcome.

    Abstract: The invention discloses a feedback sampling control circuit for a lamp driving system having a feedback loop, in that the feedback sampling control circuit includes a switch and an effective current sampling controller. The switch is electrically coupled in the feedback path of the lamp driving system. The effective current sampling controller controls switching of the switch based on a voltage or current signal from a high voltage terminal of the lamp, such that an effective current actually sampled by a feedback controller in the lamp driving system is controlled so that a current component of a parasitic capacitance contained in the effective current is minimized. Thereby, the disadvantage caused by the leakage current through the parasitic capacitance can be eliminated and it is thus possible to precisely control the lamp current and to obtain a stable brightness quality.

    Abstract: A lamp current control device includes an electronic power switch, a transformer, a current transformer and a pulse width modulation (PWM) IC. The transformer has its primary side connected to the electronic power switch and a secondary side connected to a lamp. The current transformer is serially connected with the primary side of the transformer. The PWM IC is coupled between a secondary side of the current transformer and the electronic power switch and uses the current transformer to feedback a feed back signal from the primary side of the transformer. The PWM IC receives and processes the feed back signal to obtain a control signal, and then the PWM IC outputs the control signal to the electronic power switch to control a pulse width outputted by the electronic power switch, thereby controlling and maintaining a brightness of the lamp.

    Abstract: A transformer includes a main body and a wire. The main body has several winding partitions and two end portions. Several leads are disposed in either end portion and a buffer region is formed between the right end portion and the right-most winding partition. An intermediate area is disposed between the buffer region and the right-most winding partition. One end of the wire is connected to one of the leads and the wire passes the right end portion. Before the wire goes into the buffer region, the wire is folded for several times and then is twisted and rolled for several turns to make the wire thicker. Next, the thicker wire is wound around the iron core in the buffer region for several turns and then the thicker wire passes the intermediate area and goes into the right-most winding partition.
