Problems solved by technology

[0004] However, when the fluorescent lamp described in Japanese Laid-Open Patent No. 62-234862 is used, the food is oxidized by the heat converted by the body of the fluorescent lamp, so that the freshness decreases rapidly
[0005] On the other hand, when a lighting device using LED elements is applied to display lighting of food, since the emission spectrum is different from that of conventional food lighting devices such as fluorescent lamps, it may contain a reduced impression) wavelength of light
In this case, the light of the lighting device disadvantageously causes a food spoilage feeling

Abstract

In a food lighting device, a blue LED element, a green phosphor, and a red LED element or a red phosphor are selected such that light synthesized by the blue LED element, the green phosphor, and the red LED element or the red phosphor becomes white light whose wavelength component in the vicinity of 580 nm or in the vicinity of 600 nm is reduced.

Description

technical field [0001] The present invention relates to a food lighting device and a meat lighting device, and more particularly to a food lighting device and a meat lighting device each including a phosphor for absorbing light and converting the light into long-wavelength light. Background technique [0002] As disclosed in Japanese Laid-Open Patent No. 62-234862 (1987), there is generally known a food lighting device or the like which includes a phosphor for absorbing light and converting the light to long-wavelength light. [0003] Japanese Laid-Open Patent No. 62-234862 discloses a fluorescent lamp (food lighting device) comprising a glass bulb, a luminescent layer formed on the inner surface of the glass bulb, and an ultraviolet absorbing layer formed between the glass bulb and the luminescent layer. non-luminescent layer. In particular, the fluorescent lamp is used for display lighting of food (seafood, meat, etc.). In this fluorescent lamp, the light-emitting layer ...
