Problems solved by technology

When changing the arrangement of products, it is necessary to change the position where the near-infrared light is irradiated according to the place where the crops are placed. However, there is a problem that it is difficult to confirm the position where the near-infrared light is irradiated visually.

Embodiment 1

[0048] [Structure of lighting system]

[0049] First, the lighting system according to Embodiment 1 will be described. figure 1 It is a schematic perspective view for demonstrating the lighting system concerning Example 1. figure 2 It is a block diagram showing the characteristic functional configuration of the lighting system 100 according to the first embodiment.

[0050] The lighting system 100 according to the first embodiment is a lighting system employed in a showcase 300 of a store where fresh produce F is displayed and a processing plant where fresh produce F is processed. For example, if figure 1 It is shown that near-infrared light IR and white light W are irradiated on the fresh produce F displayed (installed) on the arrangement surface A of the showcase 300 . That is, if figure 2 As shown, the lighting system 100 is used to irradiate the fresh produce F with the white light W emitted by the white light source 210 and the near-infrared light IR emitted by the ...

Embodiment 2

[0088] In the lighting system as in the first embodiment described above, it is possible to easily confirm the irradiation range of the near-infrared light IR. However, when the near-infrared light IR is not irradiated due to a failure of the near-infrared light source 220 or the like, a human cannot visually recognize the near-infrared light IR, and thus cannot be confirmed. In Embodiment 2, the lighting system further includes a photoelectric sensor to detect the light emitted by the near-infrared light source 220 . In addition, the same symbols are attached to the structures that are substantially the same as in the first embodiment, and repeated explanations may be omitted or simplified.

Embodiment 3

[0116] In the lighting systems according to the first and second embodiments, the white light W and the near-infrared light IR are emitted so that the near-infrared light irradiation range IRA overlaps with the white light irradiation range WA. Here, for example, when the layout in a store is changed, it is necessary to change the emission directions of white light W and near-infrared light IR emitted by the lighting devices constituting the lighting system, or to move the positions of the lighting devices. The lighting system of the third embodiment further includes a communication unit and a movable unit in the lighting system of the first embodiment. The communication unit obtains the position information of the fresh products in the store, and the movable unit changes the emitting directions of the white light W and the near-infrared light IR according to the position information. In addition, the same symbols are attached to the structures that are substantially the same ...

Abstract

The invention provides a lighting system making it easy to confirm the irradiation position of near-infrared light. The lighting system (100) that irradiates a fresh product (F) with light is provided. The lighting system (100) includes a white light source (210) that emits white light (W) and a near-infrared light source (220) that emits near-infrared light (IR) having at least one peak wavelength in a wavelength range of from 700 nm to 1100 nm, inclusive. The near-infrared light at least partially overlaps an area illuminated by the white light on a placement surface (A) on which the fresh product (F) is placed.

Description

technical field [0001] The present disclosure relates to a lighting system for irradiating fresh produce with light. Background technique [0002] Conventionally, techniques for maintaining the freshness of harvested crops (fresh products) have been proposed. As an example of a technique for maintaining the freshness of crops, there is a technique of irradiating light on crops (for example, refer to Patent Document 1). [0003] The technique for maintaining the freshness of the crops described in Patent Document 1 is a technique for maintaining the freshness of the crops by irradiating near-infrared light to the crops. Here, the crop is at least one selected from the group consisting of fresh vegetables (root vegetables and garlic), fresh fruits, and fresh flowers. [0004] Patent Document 1: International Publication No. 2013 / 031925 [0005] Furthermore, human eyes can perceive light with a wavelength in the range of approximately 400 to 700 nm, but light with wavelength...
