Abstract: この発明のハロゲンランプ(100)は、ガラス製のバルブ(11)と、当該バルブの内部に挿入されたフィラメント(12)と、一対の金属箔(151、152)と、一対のアウターリード(161、162)とを備える。各金属箔は、一端が前記フィラメントに、他端が前記アウターリードに溶接されている。前記金属箔は、ガラス製のスリーブに収納された後、当該スリーブとともに前記バルブの内部に挿入される。その後、前記バルブは、軟化するまで加熱され、その内部が減圧されることにより収縮し、前記金属箔を内部に封止する。形成された封止部は、前記バルブのその他の部分に比べて、前記スリーブの分だけガラスの量が多くなっているので、当該封止部の形状が安定化される。

Abstract: PROBLEM TO BE SOLVED: To provide a lighting device which can be efficiently installed in an installation space having constraints, without deteriorating the quality of an irradiation image.
SOLUTION: A reflecting mirror 37 is disposed on an optical axis O of a lens optical system 21 for controlling outgoing light from an LED 12, and by reflection on a reflecting surface 37a of the reflecting mirror 37; an optical path of a beam outgoing from a projection lens 23 is changed. Accordingly, as in the case where it is difficult to ensure sufficient depth in the irradiating direction of illumination light, even when the installation space 42 has constraints, the lighting device 1 can be installed, without sacrificing the required distance, and the like, in the optical axis O direction, between optical members configuring the lens optical system 21.

Abstract: PROBLEM TO BE SOLVED: To attain improvement in flicker and improve possible short lifetime of a lamp caused by this improvement measure. SOLUTION: The DC voltage input from a power supply 11 is stepped down by a converter 12 and supplied to an inverter 15. The inverter 15 converts the DC power input into an AC power, and by generating a high-voltage voltage by a lamp starting circuit, supplies it to a high pressure discharge lamp 17 to light it. The lamp voltage at the time of lighting is detected by a lamp voltage detection part 13 and the detection result is supplied to a control part 18. The control part 18, when it determines that it is a prescribed voltage or more, outputs an output pulse d with widened duty width by output from a PWM control part 19 and increases the DC voltage output from the converter 12 and increases the power to be supplied to the discharge lamp 17. By detecting the increase in the lamp voltage and increasing the power to be supplied to the discharge lamp 17 when it increases, flickering can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
