Ecological freshness-retaining illuminating lamp and freshness retaining equipment

Abstract

The invention relates to an ecological freshness-retaining illuminating lamp and freshness retaining equipment. The ecological freshness-retaining illuminating lamp comprises a lamp housing, a lampshade, a radiator, a drive power supply, an LED combined light source and an electrode, wherein light emitted by the LED combined light source is 440-455nm blue purple light needed for plant photosynthesis and 650-680nm long-wave-band red light, which are matched with full-spectrum white light with relative low spectral energy to regulate spectral energy of blue purple light and long-wave-band red light, so that plant photosynthetic production and respiration consumption reach physiological equilibrium, and full-spectrum white light is beneficial for generation of chlorophyll. Far-infrared light-emitting paint is coated on the surface of the lampshade and / or far-infrared light-emitting powder is mixed in the lampshade material, and the lightshade absorbs ambient light and thermal radiation, and releases 8-14-micron far-infrared light; and the far-infrared light generates resonance with free water molecules in picked vegetables, fruits, fresh cut flowers and the like to restrain water transpiration loss, so that the quality guarantee periods of the picked vegetables, fruits, fresh cut flowers and the like are prolonged.

Description

technical field [0001] The invention relates to the technical fields of semiconductor lighting, fluorescent materials and ecological plant preservation, in particular to an ecological fresh-keeping lighting lamp and fresh-keeping equipment. Background technique [0002] LED lights have many advantages such as high luminous efficiency, long service life, low energy consumption and diverse spectrum, and are used more and more widely. At present, there has been a combination of LED light sources instead of sunlight for crop planting lighting, which solves the problems of slow plant growth, unhealthy growth, and unsatisfactory photosynthesis effects when the natural light time is short and the light intensity is lower than the light compensation point. In the prior art, no technical solution has been found to apply the LED light source to the fresh-keeping field of vegetables, fruits, and fresh-cut flowers, and can achieve a good fresh-keeping effect. [0003] In the field of v...

AI Technical Summary

Problems solved by technology

The fresh-cut flower industry is mainly concentrated in Yunnan Province, with an annual output value of more than 60 billion. However, due to lagging fresh-keeping technology, sales and exports of some varieties have been greatly affected

[0004] At present, the fresh-keeping methods of fruits and vegetables in China are mainly sealed packaging, low-temperature storage, aeration, chemical treatment, etc., in order to inhibit the physiological reaction of fruits and vegetables to achieve the purpose of fresh-keeping fruits and vegetables, but the effect is not very satisfactory and the construction cost and operating cost are very high

If sealed packaging and refrigeration methods are used to keep fresh, the dry matter consumed by the respiration of fruits and vegetables cannot be effectively inhibited, and the water lost by transpiration gathers in the sealed bag to provide a breeding ground for microbial reproduction, causing the fruits and vegetables to rot and deteriorate.
