Disclosed are a lighting apparatus and a lighting control system. The lighting apparatus includes a heat radiation frame, at least one light emitting device on the heat radiation frame, a diffusion frame provided on the heat radiation frame to protect the at least one light emitting device and diffuse a light emitted from the at least one light emitting device, and a support frame provided under the heat radiation frame and having a receiving space to receive at least one module. The module includes a wireless communication module to transmit or receive a control single of the at least one light emitting device. The power supply module is physically separated from the wireless communication module.

A lighting device may include a channel-shaped housing having two ends with a main axis of the housing extending between the ends, a pair of mounting fixtures for a pair of light radiation sources within the housing with the light radiation sources radiating light radiation in opposite directions along the main axis, and a pair of reflectors each facing a respective one of the mounting fixtures to receive light radiation along the main axis and reflect it to the outside of the housing.

A lighting apparatus including a base is provided. The base includes a through-hole. The through-hole is aligned with an optical path of laser light for receiving and transmitting the laser light. A light emitter which, when irradiated with the laser light transmitted through the through-hole, radiates light by converting a wavelength of the laser light. An attachment component is provided on the base for attachment of the light emitter to the base. The light emitter is removable from the base. A light blocker opens the optical path of the laser light by being contacted by the light emitter when the light emitter is attached to the base, and blocks the optical path of the laser light when the light emitter is removed from the base.

A guide display device which is installed in a predetermined direction includes: a first screen which is parallel to the predetermined direction; a first light source which illuminates the first screen; a cover which is provided above the first screen in the predetermined direction and projects in a direction crossing the first screen to block light from above the guide display device and cast a shadow upon an area of the guide display device; a second light source which illuminates the area on which the shadow cast; and a controller which causes at least the second light source to perform optical communication.

Provided are a light source circuit unit that improves light extraction efficiency, as well as an illuminator and a display that include such a light source circuit unit. The light source circuit unit includes: a circuit substrate having a wiring pattern on a surface thereof, the wiring pattern having light reflectivity, a circular pedestal provided on the circuit substrate, a water-repelling region provided at least from a peripheral edge portion of the pedestal to a part of a side face of the pedestal, and one or two or more light-emitting device chips mounted on the pedestal, and driven by a current that flows through the wiring pattern.
