Title: Switching power supply
Inventor: TSUJI HITOSHI
IPC: H02M3/335
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply whose output can be stabilized and controlled satisfactorily. SOLUTION: A charging control circuit 20 is installed. When a switching element 4 is turned on and when the voltage of a capacitor 2 is less than a set voltage, a switching element 11 is turned on, the energy of a power supply 1 electrifies the switching element 11 and an inductance 12, and the inductance 12 stores the energy. When the switching element 4 is turned off, the charging control circuit 20 turns off the switching element 11, and the stored energy of the inductance 12 is supplied to the capacitor 2. When the switching element 4 is turned on, the switching element 11 is turned off, and the stored energy of the inductance 12 is supplied to the capacitor 2.  When the switching element 4 is turned on and when the voltage of the capacitor 2 is at the set voltage or higher, the switching element 11 is kept being turned off, the inductance 12 cannot store energy so as to restrain the rise in the voltage of the capacitor 2, and the voltage of the capacitor 2 is stabilized and controlled to the set voltage. The stabilization of the output of an apparatus can be controlled satisfactorily, and the circuit efficiency of the apparatus can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To improve the parallesism of an irradiating light beam for irradiating a liquid crystal panel with the beam and to suppress the irregularity of brightness of a projected image when a light source having an arc length between two electrodes is used. SOLUTION: A transmitting light beam from the vicinity of an electrode 2 of a light source 3 is refracted by a collimator lens 5 and is made incident on a second optical element 52 composing an optical means 50 while narrowing it to the optical axis 30. A transmitting light beam from the vicinity of the other electrode 1 is refracted by the collimator lens 5 and is made incident on a first optical element 51 composing the optical means 50 while widening it to the optical axis 30. The first optical element 51 refracts the incident light beam by the same angle as that of a luminous flux refracted from the vicinity of the electrode 2 through the collimator lens 5 and irradiates the second optical element 52 with the beam.  The second optical element 52 refractes the incident beam from the first optical element 51 and the luminous flux refracted from the vicinity of the electrode 2 through the collimator lens 5 in nearly parallel with the optical axis 30 and irradiates a liquid crystal panel 6 with the beam. Consequently, the parallelism of the luminous flux projected on the liquid crystal panel 6 is improved.
