LED light source for fresh illumination

Abstract

The invention discloses an LED light source for fresh illumination. The LED light source comprises a near-purple light LED wafer at a level of 410-415 nm and 45-50 mw, a blue light LED wafer at a level of 445-450 nm and 60-65 mw, an EMC bracket, fluorescent glue and packaging glue, wherein the near-purple light LED wafer and the blue light LED wafer are arranged on a bowl of the EMC bracket; the near-purple light LED wafer and the blue light LED wafer are connected in series; the anode and cathode of the EMC bracket are connected; the packaging glue is coated on the near-purple light LED waferand the blue light LED wafer; the fluorescent glue is dispensed in the bowl of the EMC bracket and baked; and the fluorescent glue is made by mixing yellow and green powder with an emission wavelength of 485 nm, yellow and green powder with an emission wavelength of 525 nm, yellow powder with an emission wavelength of 555 nm, red powder with an emission wavelength of 610 nm, red powder with an emission wavelength of 630 nm and red powder with an emission wavelength of 650 nm with glue, and has a color gamut of 3000K. The LED light source is capable of providing a bright illumination environment for meat food.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED light source used for lighting fresh produce lamps. Background technique [0002] LED fresh light is a new generation of special lighting designed for fresh food lighting. Through the color mixing design principle, it overcomes the spectral defects of LED lights, showing a lighting effect that is close to or even better than traditional light sources, highlighting the color characteristics of fresh food, and effectively Improve the attractiveness of fresh food area to customers. In addition, the cold light source technology derived from LED (the spectrum does not contain infrared and ultraviolet rays), effectively prolongs the freshness period of fresh food. The use of fresh light should combine the characteristics of fresh food, especially the color (or color temperature of white light) and color rendering. The color rendering index Ra is not lower than 80, and the color r...

AI Technical Summary

Problems solved by technology

[0003] In the existing market, most of the LED light sources for fresh food lighting are R9>50, and the light color quality of R12 parameters is less than 70. This invention aims to find out the defects of the display effect deviation problem caused by the low R12 parameter of the existing fresh food lights.
