Abstract

The invention discloses a method for improving color purity during production of an LED lamp. The method comprises the steps as follows: during production of LED lamp beads in the LED lamp, acquiringthe color scheme of the to-be-produced LED lamp, and selecting the LED type according to the color scheme of the to-be-produced LED lamp; determining the color gamut range where LED color coordinatesare located according to the LED type and a CIE 1931 chromaticity diagram; during production of a lampshade of the LED lamp, acquiring the bulb type of the to-be-produced lampshade, and adding corresponding toner during production of the lampshade according to the bulb type of the to-be-produced lampshade; matching the LED lamp beads produced according to the LED type with the produced lampshade to produce the LED lamp. Therefore, the color purity of the LED lamp is effectively improved, the consumed cost for production of the LED lamp with high color purity is greatly reduced, meanwhile, optional color gamut and main wavelength range of the LED lamp are enlarged, and practicability of the production method is enhanced.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a method for improving color purity when making LED lamps. Background technique [0002] Color purity, that is, the degree of saturation of the single hue contained in the color, is also called chroma; there are many factors that determine the color purity. From the perspective of light, the simpler the wavelength of the light wave, the higher the color purity. [0003] In the existing manufacturing process of LED lamps, if it is necessary to produce LED lamps with high color purity, monochromatic light of a specific wavelength is often used; however, the cost of this manufacturing method is high, and the optional color gamut and The dominant wavelength range is narrow, which has great limitations in use. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. F...
