    • PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp device allowing a required rotation level to be easily recognized when an electrodeless discharge lamp is attached to a coupler. SOLUTION: The coupler 2 is provided with tentatively-stopping springs 24 tentatively stopping and holding a base 4 of the electrodeless discharge lamp 1. Positioning lines 43a are added at two points interposing each tentatively-stopping spring 24 when attachment by bayonet connection is completed in the base 4. That is to say, the attachment is completed when the base 4 is rotated to a position where each tentatively-stopping spring 24 is interposed between the positioning lines 43. By the positioning lines 43a, the level to rotate the base 4 is easily recognized in attaching the electrodeless discharge lamp 1. COPYRIGHT: (C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To lower a starting voltage of a discharge lamp by arranging a switching means for impressing a voltage to the discharge lamp for turning it on and switching a first impression state based on an alternating current voltage to a second impression state based on pulsating direct current voltage. SOLUTION: A lighting device impression a voltage to a neon bulb (discharge lamp) 10 for turning it on is provided with an inverter 1 and a switching circuit 2. The inverter 1 turns on the neon bulb 10. The switching circuit 2 switches a first impression state based on an alternating current voltage to a second impression state based on a pulsating direct current voltage. Until the neon bulb 10 is actuated by means of this lighting device, the first impression state based on an impression voltage Vo, which is an alternating current, is maintained. After the neon bulb 10 is actuated so as to be lighted, that is, after a current Io flows, a switch to the second impression state based on a pulsating direct current voltage is carried out by means of the switching circuit 2, so that a shifting stripe is prevented and light emitting efficiency can be improved.

    • PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which has good efficiency of the lamp load even when the lamp is on in the low light flux dimmer condition and can preclude darkening of the end of the lamp or its being put off in the dimmer condition. SOLUTION: Piezo transformers A and B having different resonance frequency are connected parallel, and a high frequency power supply 1 for driving the transformers A and B is connected with their primary side terminals, while one end of a discharge lamp load 2 is connected with their secondary side terminals. When the lamp load 2 is full lighted, the drive frequency of the power supply 1 is controlled so that the transformers A and B are driven near the resonance frequency f1 of the transformer A, and when lighted in dimmer condition, the two transformers A and B are driven upon lowering the drive frequency by a dimmer control circuit 5 down to near the resonance frequency f2 of the transformer B. Even when the lamp load 2 is lighted in dimmer condition, a high efficiency at the same level as fully lighted can thereby be maintained.

    • PROBLEM TO BE SOLVED: To eliminate a danger of short-circuiting on secondary side of a transformer, while the device is miniaturized. SOLUTION: This device is equipped with a discharge lamp La and a piezoelectric transformer 2 by which a high voltage is generated at a power generating part 4 by applying an alternate current voltage to a driving part 3 and electric power is transmitted to the discharge lamp La. In this case, while the piezoelectric transformer 2 is formed in a thin plate, the discharge lamp La is made of a direct tube type, and while the discharge lamp La is close mounted so that at least a part of it confronts to the power generating part 4 of the piezoelectric transformer 2, a cable of an outside connection line 6 is connected only to the driving part 3 of the piezoelectric transformer 2, a driving circuit 5 which oscillates in the neighborhood of a frequency close to a resonance frequency of the piezoelectric transformer 2 is connected to the driving part 3 of the piezoelectric transformer 2, so that lighting of the discharge lamp La is maintained by activating the piezoelectric transformer 2 in the neighborhood of a frequency close to the resonance frequency to transmit electric power from the power generating part 4 to the discharge lamp La.

    • PURPOSE:To reduce the noise of harmonic radiation and to prevent its adverse effect inflicting on the circumferential electronic apparatuses by a method wherein the quality of material of a first and a second cores is properly selected, the permeability of the first core is made higher than that of the second core in the fundamental frequency of coil exciting circuit, and the frequency in a harmonic region of the former is made lower than the latter. CONSTITUTION:The quality of material of a first core 1 and a second core 2 is selected in such a manner that the permeability of the first core 1 becomes higher than that of the second core 2 in the fundamental frequency of coil exciting current and that the permeability of the former becomes lower than that of the latter in a higher harmonic region. Accordingly, the iron loss of the device is suppressed in the fundamental frequency of coil exciting current, and heat generation become small. Also, the permeability of the second core 2 becomes higher in the frequency of the higher harmonic region, and leakage to outside of magnetic flux generated by the frequency of coil exciting current in the higher harmonic region is reduced. As a result, higher harmonic radiant noise is reduced, and the adverse effect inflicting on the circumferential electric apparatuses and the increase in power consumption of the device can be prevented.

    • PURPOSE:To increase the variable amount of inductance by a method wherein a wire- wound bobbin is provided, and recessed and protruding parts, which will be attached to said bobbin by being pinched from both ends, are formed side by side in the circumferential direction on the butt-together surfaces of the inner magnetic path and the outer magnetic path. CONSTITUTION:Pot cores 11 and 12 are composed of inner magnetic paths 13 and 15, which pass through a bobbin 10, and the outer magnetic paths 14 and 16 which are externally fit to the bobbin 10. The butt-together surfaces 17, 18, 19 and 20 of the inner magnetic paths 13 and 15, and the outer magnetic paths 14 and 16 are divided into two parts of protruding parts 21, 23, 24 and 25, and recessed parts 22, 24, 26 and 28 in circumferential direction. As the distance between magnetic bodies becomes smaller and an opposing area becomes wider, the magnetic reluctance becomes smaller; the magnetic reluctance becomes larger in the order of the state of theta=0 deg. (the state wherein the protruding parts 21 and 25, and the protruding parts 23 and 27 are opposingly positioned) theta=90 deg. and theta=180 deg., while the inductance becomes lower. At the same time, the variable amount of inductance is increased compared with the case of the where the recessed and protruding parts are formed only in the inner magnetic parts as by the method heretofore in use.
