Abstract: An information processing apparatus acquires first relevance information indicative of a relevance between space identification information identifying a space in a building and device-installation information that is indicative of a device or an installation and associated with the space identification information; acquires modification information for modifying an association between the space identification information and the device-installation information in the first relevance information; generates second relevance information indicative of a new association between the space identification information and the device-installation information on the basis of the modification information; and outputs the second relevance information.

Abstract: An information processing apparatus acquires first spatial information including division information indicative of divisions in a building and device-installation information indicative of a device or an installation disposed in a division; acquires space use information associating the device-installation information and use information indicative of a space use in connection with a device or an installation disposed in a space with each other; generates second spatial information by associating the use information with the division information included in the first spatial information on the basis of the space use information; and outputs the second spatial information.

Abstract: Disclosed is a high-pressure discharge lamp (100) that reduces the occurrence of cracks even under high mercury vapor pressure. The high-pressure discharge lamp (100) is provided with a glass arc tube (102) including a light-emitting part (103) and a sealing part (104) connected to the light-emitting part (103), the light-emitting part (103) enclosing a discharge space, and a pair of electrodes (101), one end of each of the electrodes (101) facing one end of the other electrode (101) in the discharge space, and another end of each electrode (101) being embedded in the sealing part (104) and connected to a metal foil (105), at least one embedded section of the pair of electrodes (101) including at least one projection (101c).

Abstract: An LED lamp has an envelope that includes a globe and a case, an interior space of the envelope being divided in two by a mount closing an opening of the globe, the lamp containing, in a globe side of the interior space, an LED and, in a case side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount, and the mount and the case are joined to the globe such that, during light emission, at least as much heat from the LED is propagated from the mount to the globe as from the mount to the case.

Abstract: An LED lamp has an envelope that includes a globe (30) and a case (50), an interior space of the envelope being divided in two by a mount (20) closing an opening of the globe (30), the lamp containing, in a globe (30) side of the interior space, an LED and, in a case (50) side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount (20), and the mount (20) and the case (50) are joined to the globe (30) such that, during light emission, at least as much heat from the LED is propagated from the mount (20) to the globe (30) as from the mount (20) to the case (50).

Abstract: Provided is a light source including a light-emitting element, an outer shell that houses therein the light-emitting element, and a base that is provided at the outer shell and receives power from the outside to cause the light-emitting element to emit light. The outer shell is electrically-insulative and light-transmissive. On at least part of the outer surface or the inner surface of the outer shell, an electrically-conductive member is provided. The electrically-conductive member is electrically connected to a grounding terminal of the lighting fixture. According to this structure, an electric charge stored on the outer surface can be discharged to the outside from the lighting fixture. This prevents the attachment of dust to the outer shell, and keeps the luminous flux close to the initial level for a long time period and reduces the amount of maintenance.

Abstract: A mount member (5) has a contact surface (27a) touching the bottom surface of an LED module (3) and protrusions (5a) protruding from the periphery of the contact surface (27a) in the thickness direction of the LED module (3) and regulating sliding motions thereof. A fixing member (6) made of a resilient, plate-like member comprises an opposing pair of flat portions (43) near the contact surface (27a) of the mount member (5) and flat tabs (44) projecting from the flat portions (43) toward the contact surface (27a) touching the upper surface of a substrate (17). The flat portions (43) of the fixing member (6) are fastened to be lower than the top surface of the substrate (17) of the LED module (3). Thus, elastically deformed areas extending from the fastened parts of the flat portions (43) through the flat tabs (44) press the substrate (17) into the mount member (5).
