Abstract

The invention discloses a lighting system having a plate-like portion having a plurality of light emitting elements provided on the surface thereof, and a case body in which one of a power supply circuit for supplying power to the light emitting elements and a power supply wire connected to an external power supply is accommodated. The lighting system is characterized in that a through-hole is formed in the plate-like portion so as to penetrate through the plate-like portion, the light emitting elements are arranged around the through-hole, a hollow cylindrical ventilation portion having no bottom is provided to the back surface of the plate-like portion so as to intercommunicate with the through-hole, and the case body is joined to one end portion of the ventilation portion; so that a gap opened to the outside in a peripheral direction of the ventilation portion is formed between the one end portion of the ventilation portion and the case body.

Description

technical field [0001] The present invention relates to a lighting device suitable for use as a high ceiling-mounted lighting device. Background technique [0002] Indoor lighting devices installed on indoor ceilings of factories, gymnasiums, commercial facilities, etc. are called high ceiling-mounted lighting devices (for example, see JP-A-2009-301718). [0003] In order to achieve energy saving and increase in lifespan of a high ceiling-mounted lighting device, it has been considered to use a light emitting element such as a light emitting diode (LED) as a light source of the lighting device. However, when a light emitting element such as an LED is used as a light source, it is necessary to efficiently dissipate heat generated from the light emitting element and a mounting board on which the light emitting element is mounted. In order to meet this requirement, it is necessary to provide a heat dissipation structure for the lighting device, such as a cooling fin, which inc...
