Intelligent fresh-keeping sterilization illumination photo-biological system applied to inside of cold storage equipment

Abstract

Disclosed is an intelligent fresh-keeping sterilization illumination photo-biological system applied to the inside of cold storage equipment. According to the technical scheme, a supporting plate for carrying cold stored food is made of a light transmission material; multi-color light-emitting diode (LED) light sources are uniformly distributed and irradiate the cold stored food; red, orange, green and blue LED light beads are adopted specifically, welded to a heat dissipation circuit board at intervals and mounted in light transmitting brackets which are used for being arranged on the inner wall in the cold storage equipment to serve as the left and right brackets of the cold stored food supporting plate; the light transmitting supporting plate is made of the light transmitting material, subjected to sand blasting, horizontally put on the light transmitting brackets on the left and right sides and used for carrying the cold stored food, and a power module, the circuit board, a relay and a single chip microcomputer controller are arranged; any time can be set to control on / off of the LEDs to perform optical fresh keeping, optical sterilization and illumination on the food in the cold storage equipment. The intelligent fresh-keeping sterilization illumination photo-biological system has the beneficial effects that the light mixing efficiency is high, the lighting coverage is wide and uniform, and the effects of fresh keeping and sterilization on the food by the cold storage equipment can be improved.

Description

Technical field [0001] The present invention relates to an integrated device for light preservation, light sterilization and light illumination applied in refrigeration equipment, especially an intelligent freshness preservation application in refrigeration equipment, which uses LED as light source, light guide material as supporting plate, and is controlled by a single-chip microcomputer system. Germicidal lighting photobiological system. Background technique [0002] At present, the light-keeping and light-sterilizing LED lamp beads in ordinary refrigeration equipment are installed on the top or side of the refrigerator. Because the effective light area of ​​the LED lamp bead is small, the efficiency of light preservation and light sterilization is very low, and many The light emitted by the LED lamp beads of different colors lacks a mixed medium, so that the fresh-keeping and sterilizing functions of the mixed light cannot be well exerted, that is, the multi-colored light...

Problems solved by technology

[0002] At present, the light-keeping and light-sterilizing LED lamp beads in ordinary refrigeration equipment are installed on the top or side of the refrigerator. Because the effective light area of ​​the LED lamp bead is small, the efficiency of light preservation and light sterilization is very low, and many The light emitted by the LED lamp beads of different colors lacks mixed media, so that the fresh-keeping and sterilizing functions of the mixed light cannot be well exerted, that is, the multi-colored light cannot be mixed well and cover the area that needs to be irradiated. Food

Therefore, the performance and efficiency of light preservation and light sterilization devices of refrigeration equipment are very low, and they lack due practical value.
