LIGHT-EMITTING DEVICE AND CULTIVATION METHOD

摘要

Disclosed is a light-emitting device (100) which accommodates a body (20) to be illuminated, wherein the light-emitting device (100) is provided with: a placement section (1) which comprises a pair of opening surfaces and has the body (20) to be illuminated placed therein; a light-guide plate (2) which guides light introduced from an end section through the interior thereof and also emits said light from a light emission surface (12); and a light source (3) which is arranged at the end section and emits light towards the interior of the light-guide plate (2). The environment in which the body to be illuminated is placed can be readily and efficiently managed as a result of the light emission surface (12) being formed with a concave construction such that the body (20) to be illuminated is surrounded by the light emission surface (12).
