Reversible photochromic LED illumination lamp

Abstract

The invention discloses a reversible photochromic LED illumination lamp. The reversible photochromic LED illumination lamp comprises a lamp bulb shell, an LED light source and a reversible photochromic layer, wherein the LED light source is arranged in the lamp bulb shell; the reversible photochromic layer is arranged on the lamp bulb shell; and the light ray emitted by the LED light source is capable of exciting the reversible photochromic layer to change a colour. According to the LED illumination lamp, the reversible photochromic layer capable of being excited by the light ray emitted by the LED light source is arranged on the lamp bulb shell, and the reversible photochromic layer is capable of filtering out light rays adverse to colour rendering in a spectrum after the colour change when the LED illumination lamp is lightened. In this way, the colour rendering index of the LED illumination lamp is increased, so that the LED illumination lamp has the advantage of being high in colour rendering index.

Description

Technical field [0001] The invention belongs to the technical field of LED lighting and relates to a reversible photo-induced variable LED lighting lamp. Background technique [0002] LED is quickly applied to the lighting field due to its advantages of high luminous efficiency, long life and no pollution, and the current LED lamp contains a large amount of yellow light in its light, which leads to the color of the whole lamp. The index is low. This is because the light that is not conducive to color rendering in the emitted light is directly shot into the external space without filtering out, which leads to the low color rendering index of the whole lamp. Summary of the invention [0003] In order to eliminate the above-mentioned defects, the present invention provides a reversible photochromic LED lighting lamp with a high color rendering index, comprising a bulb shell, an LED light source and a reversible photochromic layer, the LED light source is arranged in the bulb shell, a...

Problems solved by technology

[0002] LED has been rapidly applied to the lighting field due to its advantages of high luminous efficiency, long life and no pollution. However, the current LED lamp contains a large amount of yellow light in the light emitted, which leads to the color rendering of the whole lamp. The index is low. This is because the light that is not conducive to color rendering is not filtered out, and it is directly directed to the external space, which leads to the low color rendering index of the whole lamp.
