Abstract: A transformer 6 and a photocoupler 5 are provided to ensure insulation between a primary side circuit section 10 connected to an alternating current power supply 2, and a secondary side circuit section 20 for applying a voltage to a lamp 4. A detection circuit section 22E, provided in the secondary side circuit section 20, detects an output voltage and an output current of the lamp 4 to detect a deviation from a predetermined power. A signal corresponding to the deviation, which has been detected by the detection circuit section 22E, is transmitted to the primary side circuit section 10 via the photocoupler 5 provided between the primary side circuit section 10 and the secondary side circuit section 20. A switching control section 13, provided in the primary side circuit section 10, carries out switching control for constant power lighting based on the signal transmitted from the photocoupler 5.

Abstract: The invention is to provide a simple and compact configuration which can still be improved in the efficiency of light condensation to a predetermined small-diametric area. The present invention is a device comprising: an arc tube 20 having a pair of main electrodes 21 and 22; and a reflector 30 for reflecting the outgoing light emitted from the arc tube 20, the electrode axis O1 of the main electrodes 21 and 22 being arranged to cross the light axis LA of the outgoing light. The reflector 30 is formed of a first reflector portion 31 having a spherical surface centered at the light generation point L0 of the arc tube 20 and a second reflector portion 32 having a curved surface different from the first reflector portion 31, and a condenser 40 that condenses the outgoing light emitted from the arc tube 20 to other than the second reflector portion 32 and illuminates the condensed light in a predetermined direction or to a predetermined area is provided.

Abstract: A concave mirror substance 1 constituting a reflector is composed of a base material having a high thermal conductivity such as aluminum etc. An infrared-to-heat converting layer 2 is film-formed by anodizing the substrate formed of aluminum etc., so as to absorb light in a wavelength range which passes through a visible light reflecting layer 4 and convert it into heat. A gloss-forming buffer layer 3 is film-formed by calcining Si resin or polyimide resin over the inner side (the light source-side surface) of infrared-to-heat converting layer 2 at high temperatures, so as to buffer the two layers in a manner that does not allow infrared-to-heat converting layer 2 and visible light reflecting layer 4 to be in direct contact with each other, and so as to reduce the influence of projections and indentations present on infrared-to-heat converting layer 2 and smoothen the light source-side surface of visible light reflecting layer 4.
