Fresh food lighting device

Abstract

The invention provides fresh food lighting device. The fresh food lighting device comprises a shell, a red light chip, a blue light chip and a green medium, wherein the shell is provided with a containing cavity, the red light chip and the blue light chip are both arranged in the containing cavity, the containing cavity is filled with the green medium, and the red light chip and the blue light chip excite the green medium to emit white light. The normalized spectrogram of the white light meets the conditions that the normalized spectrogram comprises a first red light wave band, the half-wave width of the first red light wave band is in a range of 15 nm-30 nm, the wave crest of the first red light wave band is a first wave crest, relative light power corresponding to the first wave crest is 0.9-1, and wavelength corresponding to the first wave crest is 645 nm-665 nm. By setting the first red light wave band with the above parameters, the generation of yellow light can be reduced, the illumination color of fresh food is relatively reduced, the displayed red color hardly looks like a dark brown color, and the color is relatively matched with an illuminated object.

Description

technical field [0001] The invention belongs to the technical field of fresh food lighting, and in particular relates to a fresh food lighting device. Background technique [0002] Fresh food lighting is a new generation of special lighting designed for fresh food lighting, which can highlight the color characteristics of fresh food, thereby stimulating people's desire to buy. [0003] At present, the spectrum used for fresh lighting in the market is mainly mixed with ordinary white light or monochromatic light, without considering the refined color management, and the special scientific adjustment corresponding to the color reduction ability of different irradiated items. . The common fresh lighting on the market usually adopts the scheme of white lamp beads + red lamp beads, which has poor light mixing effect. There is also a blue light chip + green phosphor + red phosphor scheme, the normalized spectrum of the fresh white light excited by it is as follows figure 1 or ...

Problems solved by technology

The common fresh lighting on the market usually adopts the scheme of white lamp beads + red lamp beads, and its mixed light effect is poor

There is also a solution of blue light chip + green phosphor + red phosphor, and the normalized spectrum of the fresh white light excited by it is as follows: figure 1 or figure 2 As shown, the resulting disadvantages are: (1) the color of fresh lighting is distorted, and the displayed red is more likely to be brownish; (2) the color does not match the object to be illuminated
