A circuit board includes a heat storage body, an insulating layer provided on the heat storage body, a wiring board provided on the insulating layer, and a heat generating component provided on the wiring board. The insulating layer is provided independently of the wiring board. The wiring board is provided with a heat transfer metal portion penetrating through the wiring board and facing the heat generating component. The insulating layer is provided with a heat transfer resin portion penetrating through the insulating layer and facing the heat transfer metal portion. The heat transfer resin portion and a part of the insulating layer are interposed between the heat transfer metal portion and the heat storage body.

A lighting apparatus includes: a linear light source having an elongated shape; and an optical component which transmits light emitted from the linear light source. The optical component has an entrance surface where the light emitted from the linear light source enters and (ii) an exit surface where the light which has entered the entrance surface exits. The optical component includes, on the exit surface, a light diffuser row including a plurality of light diffusers which are arranged in a line. In a plan view of the exit surface, a first direction in which light-emitting elements included in the linear light source are arranged intersects with a second direction in which the light diffusers are arranged.

Lighting apparatus and moving object

The control device individually controls operations of the two or more lighting devices. Each lighting device includes a light source, a sensor for measuring light intensity of the light source, and a controller circuit for controlling the light source. The control device includes a replacement detector circuit, and the replacement detector circuit determines whether any of the lighting devices has been replaced, and obtains a determination result distinguishing a replacement lighting device from remaining lighting device(s). When the replacement detector circuit has obtained the determination result, the control device controls at least one of the lighting devices based on the measurement value outputted from the sensor of the replacement lighting device and the measurement value(s) outputted from the sensor(s) of the remaining lighting device(s), so that a difference between light intensity of the replacement lighting device and light intensity derived from the remaining lighting device(s) falls within a predetermined range.

An elongated lighting apparatus includes: a light source (linear light source); and an elongated optical component which transmits light emitted from the light source. The optical component has an elongated entrance surface where the light from the light source enters and an elongated exit surface where the light which has entered the entrance surface exits. The optical component includes light diffusers. Among the light diffusers, at least one of light diffusers disposed near a first end of the optical component diffuses the light from the light source, toward the first end side of the optical component more widely than (i) light diffusers disposed near a second end of the optical component do or (ii) light diffusers disposed near the center of the optical component do. The first and second ends, and the center of the optical component are in the longitudinal direction of the optical component.

An illumination device includes a first light source and a second light source, a sensor, and a controller. The controller repeats a plurality of operation cycles, one operation cycle being a set of a first period in which only a detection target light source is caused to emit light and a second period in which the first light source and the second light source are caused to emit light. The sensor outputs detection values of detected light amounts in the first period. The controller controls the light source such that light amount of the light source fall in a target range, based on a detection result that corresponds to a value corresponding to the detection values of the light amount detected a predetermined number of times.

Illumination device and illumination system and mobile body including the same

A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft.

Lighting system

This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.
