Abstract

The utility model is applicable to the technical field of lighting and provides a high-color-rendering LED module. The high-color-rendering LED module is provided with multiple LED lattices different in color rendering index. The LED module is formed by matching the LED lattices different in color rendering index, so that emission wavelength of the LED module is increased, the color rendering index of the LED module is higher than the maximum color rendering index of the LED lattices. Further, light intensity of each LED lattice is kept constant, and accordingly, color rendering of the LED module is improved integrally, and high luminance of the LED module is kept.

Description

A kind of high-color rendering LED module

Technical field

The utility model belongs to lighting technical field, relates in particular to a kind of high-color rendering LED module.

Background technology

LED illumination have environmental protection, overlong service life, energy-efficient, anti-adverse environment, simple in structure, volume is little, in light weight, characteristics such as response is fast, operating voltage is low and security is good; Therefore be described as after incandescent lamp, fluorescent lamp and electricity-saving lamp the 4th generation lighting electric light source, or be called the 21st century green light source.

Have at present through the colour rendering of interpolation red fluorescence powder, and the luminous flux of red fluorescence powder is lower, has reduced the brightness of LED product with each unit in the raising LED product.

The utility model content

The purpose of the utility model embodiment is to provide a kind of high-color rendering high-brightness LED module, is intended to solve the existing lower problem of high-color rendering LED module brightness.

The utility model embodiment is achieved in that a kind of high-color rendering LED module, has the mutually different LED dot matrix of a plurality of colour rendering indexs; The glow color of each LED dot matrix is consistent, and the LED in each LED dot matrix comprises the LED wafer and is complementary to produce the fluorescent material of white light with said LED wafer; LED wafer in the different LED dot matrix is covered by the fluorescent glue of different colour rendering indexs, and the LED wafer in the same LED dot matrix is covered by the fluorescent glue of same colour rendering index.

The utility model embodiment is by mutually different LED dot matrix cooperation formation of a plurality of colour rendering indexs LED module; Enriched the emission wavelength of LED module; And the colour rendering index that makes the LED module wherein the LED dot matrix of high color rendering index (CRI) is also high; And the light intensity of each LED dot matrix is constant, thereby improves the colour rendering of whole LED module, and keeps high brightness.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The high-color rendering LED module that the utility model embodiment provides is LED lamp panel module or LED lamp bar module, and it has the mutually different LED dot matrix of a plurality of colour rendering indexs.As shown in Figure 1; LED lamp panel module includes but not limited to the LED dot matrix A that is made up of LED A1, LED A2, LED A3...; The LED dot matrix B that forms by LED B1, LED B2, LED B3..., the LED dot matrix C that forms by LED C1, LED C2, LED C3..., the LED dot matrix D that forms by LED D1, LED D2, LED D3...; Wherein the colour rendering index of LED dot matrix A, B, C, D is respectively 75,85,87,82, has enriched the emission wavelength of LED lamp panel module thus.This moment, the colour rendering index of whole LED lamp panel module was 90, and the LED dot matrix D of high color rendering index (CRI) is also high, and the light intensity of each LED dot matrix is constant, thereby improved the colour rendering of whole LED lamp panel module, and kept high brightness.

As shown in Figure 2, LED lamp bar module includes but not limited to a by LED ₁, LED a ₂, LED a ₃... the LED dot matrix a of composition, by LED b ₁, LED b ₂, LED b ₃... the LED dot matrix b of composition, by LED c ₁, LED c ₂, LED c ₃... the LED dot matrix c of composition, wherein the colour rendering index of LED dot matrix a, b, c is respectively 80,86,88, has enriched the emission wavelength of LED lamp bar module thus.This moment, the colour rendering index of whole LED lamp bar module was 92, and the LED dot matrix c of high color rendering index (CRI) is also high, and the light intensity of each LED dot matrix is constant, thereby improved the colour rendering of whole LED lamp bar module, and kept high brightness.

Usually, the glow color of each LED dot matrix is consistent, and the LED in each LED dot matrix comprises the LED wafer and is complementary with the fluorescent material of generation white light with this LED wafer, thereby makes the color height of LED module consistent.

The utility model embodiment mixes the fluorescent glue that glue forms different colour rendering indexs by the fluorescent material of different colour rendering indexs; LED wafer in the different LED dot matrix is covered by the fluorescent glue of different colour rendering indexs; LED wafer in the same LED dot matrix is covered by the fluorescent glue of same colour rendering index; Help to realize the solid colour of each LED dot matrix in the LED module, and colour rendering index is different.

Each LED dot matrix can adopt the identical blue light wafer of wavelength in the aforementioned LED module, so promptly can not occur owing to the asynchronous look that produces of wafer decay floats phenomenon.

By on can know that the high color rendering index (CRI) dot matrix has been confirmed the colour rendering index basis of whole LED module, other dot matrix have enriched the emission wavelength composition of LED module, thereby improve the colour rendering index of whole LED module.Because other dot matrix can adopt the lower pattern of colour rendering index, thereby can satisfy the requirement of high brightness, make LED module finished product demonstrate the high-color rendering high brightness.Yet require chromaticity coordinates unanimity, i.e. solid colour between each dot matrix.
