Abstract

The invention belongs to the technical field of lighting, and particularly relates to an LED lighting device which comprises an LED light source and a driving system of the LED light source. The LED light source comprises a blue light chip suitable for emitting blue light, a first phosphor suitable for being excited by the blue light to generate first fluorescence, and a second phosphor suitable for being excited by the blue light at least to generate second fluorescence. The blue light, the first fluorescence light and the second fluorescence are mixed to form output light; the spectral energy distribution percentage of the output light is 380-480 nm: 23-43%; 480-580 nm: 11%-31%; and 580-750 nm: 36%-56%; and the color gamut center coordinate of output light is (x, y) = (0.29 + / -0.03, 0.23 + / -0.03). The output light has the effects of brightening food color and weakening color distortion; when a user purchases food, the authenticity of the color of the food can be judged according to the color of the skin of the user when the user is illuminated, and then high-quality food is selected and purchased; and the lighting device can also be used for conventional lighting.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED lighting device and a food display cabinet. Background technique [0002] In food (such as meat, vegetable) supply showcases, fluorescent lamps are usually used for concentrated lighting. The emission spectrum of such lamps usually contains supersaturated red light components to make meat or red vegetables and fruits more vivid. , but the green and yellow are severely lacking, making the lighting effect of this lamp less natural, and the color of the illuminated food and other nearby objects is too red, which deviates greatly from its true color. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an LED lighting device, including but not limited to solving the problem that the food color presented by conventional food lighting lamps is reddish and unreal. [0004] In order to achieve the above purpose, t...
