The antenna extends through the first insertion portion and the second insertion portion.

Light fixture

Luminaires in a lighting system have mutually different addresses. A setting device includes a communication unit that transmits an address request signal at a first transmission power level and a control unit that determines whether a total number of the addresses transmitted from one or more of the luminaires in response to receiving the address request signal is within a target range. The control unit instructs the communication unit to transmit the address request signal at a transmission power level different from the first transmission power level when the total number of the addresses is outside the target range, and executes pairing of the one or more of the luminaires that responded to the address request signal with a wireless controller when the total number of the addresses is within the target range.

A lighting driving device is to be installed on a part of a structure. The lighting driving device includes: a metallic casing including a slit through which radio waves pass; a communication circuit which is housed in the metallic casing and performs wireless communication; a driving circuit which is housed in the metallic casing and supplies power to a light emitter; and an insulator which is disposed on the metallic casing and spaces apart the slit from the part of the structure.

Lighting driving device and lighting apparatus

A luminaire is provided. The luminaire includes a luminaire body and a first wireless communication device. The first wireless communication device receives a first control signal wirelessly transmitted from an outside of the luminaire body, and wirelessly transmits a second control signal in response to the first control signal. The luminaire body includes: a light source; a second wireless communication device that receives the second control signal; a light emission control circuit that is electrically connected to the second wireless communication device and controls a light emission state of the light source according to the second control signal; and a case that, with or without a cover, houses the second wireless communication device and the light emission control circuit. The first wireless communication device is attached to the luminaire body.

A conveyor belt () is formed by coupling multiple chain linksaligned in a conveyance direction X. The chain link () is provided with multiple recess parts () and first hinge parts () protruding in the conveyance direction X from positions between which each of the recess parts () is placed. If some object hits on an outer end of the conveyor belt () to apply force to the first hinge part (), a section including the first hinge part () and a bulging part () pivots about a fulcrum at an outer base end of the first hinge part () to deform this section. In this invention, a point of action where force acts on the conveyor belt () and the center of pivotal motion of the first hinge part () and the bulging part () are determined to be spaced by a relatively short distance.

Conveyor belt and belt constituent members

In a conveyor belt composed of hinged modular links, one or more of the links are composed of multiple parts at least one of which is in the form of an guide-engaging element having a protruding guide-engaging section, a pair of laterally spaced hinge knuckles on a leading or trailing edge of a base, and a single hinge knuckle on the opposite edge. The single hinge knuckle is positioned opposite the mid point between the two laterally spaced hinge knuckles. The sum of the cross-sectional areas of the two laterally spaced hinge knuckles is equal to the cross-sectional area of the single hinge knuckle. The widthwise cross-sectional area of the base of the guide-engaging element is equal to the widthwise cross-sectional area of any portion of the base of any other modular link in the belt having the same width as that of the base of the guide-engaging element.
