Abstract: An indoor illumination device includes a compartment-side ceiling member, a lighting body support base, a direct illumination lighting body, and an indirect illumination lighting body. The lighting body support base is attached to the compartment-side ceiling member. The direct illumination lighting body is supported by a lighting body support base such that an illumination section of direct illumination lighting body is disposed below the compartment-side ceiling member and direct light is radiated into the passenger compartment. The indirect illumination lighting body is supported by a lighting body support base such that an illumination section of the indirect illumination lighting body is disposed above the compartment-side ceiling member and reflected light is radiated into the passenger compartment. The lighting body support base extends in a vehicle forward/rearward direction at an outer side portion of the ceiling section in the passenger compartment in a vehicle width direction.

Abstract: Light (light (L1)) at peak luminous intensity in a light distribution of a first region (12a) of a light-irradiating surface (12) is sent to a first region (32a) of a target surface (32) via a first region (22a) of a reflecting surface (22). Light (light (L2)) at peak luminous intensity in a light distribution in a second region (12b) of the light-irradiating surface (12) is sent to a second region (32b) of the target surface (32) via a second region (22b) of the reflecting surface (22). An optical distance from the first region (12a) of the light-irradiating surface (12) to the first region (32a) of the target surface (32) via the first region (22a) of the reflecting surface (22) is greater than an optical distance from the second region (12b) of the light-irradiating surface (12) to the second region (32b) of the target surface (32) via the second region (22b) of the reflecting surface (22). The luminous intensity of the light (L1) is higher than the luminous intensity of the light (L2).

Abstract: A billiard table top lighting apparatus provides substantially uniform lighting across the surface of a billiard table surface. In one form, the lighting apparatus includes a frame supporting lights that are non-centrally placed such that no lights are supported above a middle portion of the billiard table surface. So configured, the frame can have an attractive profile and further mount additional items above the billiard table surface to enable a variety of other features. For example, the frame may support one or more cameras, one or more motion sensors, one or more microphones, and/or one or more computing devices to enable any of a variety of innovative features. Such features could include automatic game play recording from one or more perspectives, merged video track storage for replay, review, and analysis, automatic lighting and dimming control, control of the apparatus from any mobile device, and the like.

Abstract: The described technology provides an electric heating apparatus with multiple heating lamps that can increase the heat emitted by a single heating apparatus, thereby allowing a minimal number of heating apparatus installations in the space where heating is needed, and can prevent fires by turning the power off immediately in the event of the heating apparatus falling off. According to the described technology, multiple heating lamps may be positioned within the reflector dish, and the heating lamps may have particular inclinations to allow a broader range of irradiation and increase efficiency in terms of installing, maintaining, and operating the electric heating apparatus; the heat of the reflector dish and the heating lamps themselves may be discharged by way of conduction at the upper portion of the reflector dish.
