Description
SYNCHRONOUS LIGHTING SYSTEM OF MULTIPLE XENON
LAMP
Technical Field
[1] The present invention relates to a synchronous lighting apparatus of multiple xenon lamps using an alternating current (AC) power source, and in particular, to a synchronous lighting apparatus of multiple xenon lamps using an AC power source allowing multiple xenon lamps disposed for being supplied with a power through the same power line to simultaneously flash lights so that a flash effect can be increased.
[2]
Background Art
[3] A xenon lamp is a lamp configured to encapsulate a xenon gas within a quartz tube and to allow lights to be generated by means of discharge occurring on the lamp, which emits lights nearest to natural lights from various light sources, so that it is widely employed for various applications such as a stroboscopic light source for pick-up by camera, a headlight for an automobile, an indoor illumination, a projector, a light source for movie photographing, and so forth.
[4] FIG. 1 is a circuit diagram illustrating a lighting circuit for using a general xenon lamp as an AC power source. Referring to FIG. 1, when a high impulse voltage is applied to an electrode for triggering Tr while a high voltage is applied between electrodes A and B, the electrodes A and B become electrically connected at that moment so that the lamp flashes lights.
[5]
Disclosure of Invention Technical Problem
[6] In order to simultaneously turn on multiple xenon lamps disposed in the lighting circuit, a trigger voltage must be simultaneously generated for each xenon lamp, which, however, has a built-in trigger voltage generation circuit, so that it is impossible to synchronize times of generating the trigger signals with each other in the respective xenon lamps, which thus makes it difficult to simultaneously turn on the multiple xenon lamps.
[7]
Technical Solution
[8] One aspect of the present invention is to provide a synchronous light system of multiple xenon lamps, which includes: an AC power line 20 for supplying a power supplied from an AC power supply 10 to a xenon lamp 30; a controller 40 disposed in
the AC power line 20 and for generating a trigger signal and supplying the trigger signal to the xenon lamp 30 through the AC power line 20; and a xenon lamp 30 for receiving a power signal overlapped with the trigger signal, separating the trigger signal from the overlapped power signal and carrying out lighting by means of the separated trigger signal.
[9] Meanwhile, the controller 40 is composed of an impulse generation circuit for trigger signal, and a transistor Tl for overlapping the impulse onto the AC power line 20 and supplying the overlapped power signal, wherein the impulse generation circuit is composed of a capacitor C, a diode D and a resistor R.
[10] In addition, the xenon lamp 30 includes a transistor T2 for generating a trigger signal voltage through the impulse voltage overlapped with the AC power line.
[H]
Advantageous Effects
[12] According to the present invention as described above, multiple xenon lamps receiving a power through the same AC power line can be simultaneously turned on for flashing lights, so that the flashing effect can be increased, which can thus enhance utilization and a performance of the xenon lamp. [13]
Brief Description of the Drawings [14] FIG. 1 illustrates a xenon lamp lighting circuit using a conventional AC power source.
[15] FIG. 2 illustrates a lighting circuit according to the present invention.
[16] FIG. 3 illustrates overlapping between a power source and an impulse waveform for trigger according to the present invention. [17] FIG. 4 illustrates multiple xenon lamp lighting circuit according to the present invention. [18]
Best Mode for Carrying Out the Invention [19] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to accompanying drawings. [20] FIG. 2 illustrates a lighting circuit for xenon lamp 30 according to the present invention, which is composed of an AC power source, a power line, a controller 40, and the xenon lamp 30 a shown in FIG. 2. [21] The controller 40 is configured to have an impulse generation circuit for trigger signal which is composed of a capacitor C, a diode D, and a resistor R. As shown in
FIG. 2, when the AC power is supplied from the AC power source, a direct current voltage is charged on the capacitor C of the impulse generation circuit of the controller
40 disposed in the AC power line 20 through the diode D and the resistor R.
[22] At this time, when a switch SW is turned on, electric charges charged on the capacitor C are rapidly discharged through a coil L2 so that a sharp impulse current flows through the coil L2, and this impulse current is induced through a transistor Tl to be overlapped with the AC power line 20.
[23] Accordingly, the impulse signal having a sharp waveform is overlapped with the
AC power voltage as shown in FIG. 3, which is then delivered to the xenon lamp 30.
[24] When such an impulse signal having a sharp waveform is overlapped with the AC power voltage and then delivered to the xenon lamp 30, the xenon lamp 30 not only receives the AC power supplied from the AC power line 20 but allows the impulse voltage overlapped with the AC power source to be induced to the coil L3 through a transistor T2, and this voltage is in turn induced to the coil L4 to be generated as a trigger signal voltage, which is applied to a trigger electrode of the xenon lamp 30 so that the xenon lamp 30 can be turned on.
[25] Accordingly, even when multiple xenon lamps 30 are disposed to receive the power through the same AC power line 20 as shown in FIG. 4, the respective xenon lamps 30 can be turned on in synchronization with each other for flashing lights so long as the AC power passes through the controller 40 and then is delivered to the multiple xenon lamps 30.
[26] Meanwhile, according to the present invention, only two strips are required for the
AC power line 20 and no additional device or transmission line is required for delivering the trigger signal, so that a configuration of the device for lighting the multiple xenon lamps 30 can be significantly simplified.
[27] In addition, the transistors Tl and T2 of the present invention have very low inductances because a ferrite core is wound with a very small number of coils, so that t here is no problem in allowing the AC power having a typical 60Hz to flow.
[28]
