Abstract
The utility model discloses an LED (Light Emitting Diode) light fitting circuit with high color rendering index, wherein a plurality of LED light sources are serially connected to form lamp strings, and the plurality of lamp strings are mutually connected in parallel; and one LED light source in each lamp string is a red LED light source, and the rest LED light sources in the lamp string are LED light sources with low color rendering indexes. According to the utility model, the LED light sources with low color rendering indexes are mixed with the red LED light source, various red LED light sources are added in the original LED light sources with poor d color rendering indexes to greatly improve the color rendering index of mixed light on the condition of invariable luminous flux.
Description
Technical field
The utility model relates to the LED lamp, particularly the LED lamp of high color rendering index (CRI).
Background technology
Because light source has strict requirement to colour rendering index (CRI) in lighting, and present very ripe aspect colour rendering of white light LEDs technology makes it to become restriction LED as the major obstacle of lighting source.The most fluorescent material that adopt blue light-emitting to add Yellow light-emitting low temperature of existing led light source chip form white light.This spectrum and natural spectrum (or perhaps standard spectrum) differ greatly, and color rendering is poor, and colour rendering index is not high.
No matter which kind of illumination light comprises LED, colour rendering index is relevant with spatial distribution.More near nature spectrum (or perhaps standard spectrum), colour rendering index is higher.Improve colour rendering index, will add the spectrum that originally lacked.But add spectrum and can reduce luminous flux.
The utility model content
The utility model is for the colour rendering index shortcoming on the low side of existing LED light fixture, be studied improvement, a kind of LED lamp circuit of high color rendering index (CRI) is provided, in the relatively poor LED light fixture of original colour rendering index, increase some red LED light sources, to reach mixed light in the situation that the constant colour rendering index of luminous flux be significantly improved.
The technical solution of the utility model is as follows:
A kind of LED lamp circuit of high color rendering index (CRI) forms the lamp string by a plurality of led light source series connection, is parallel with one another between a plurality of lamp strings; It is the red-light LED light source that a led light source is arranged in each lamp string, and remaining led light source is low colour rendering index led light source in the described lamp string.
Useful technique effect of the present utility model is:
Compare with the LED light fixture of the low colour rendering index of tradition, because the utility model adopts low colour rendering index led light source to design with the mode that the red-light LED light source mixes, in the middle of original light source aluminium base or light source module, add some red-light LED light sources, greatly improved the colour rendering index of original light fixture, aspect luminous flux, also be guaranteed simultaneously.
Description of drawings
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 1, series connection forms the lamp string to the utility model, is relation parallel with one another between a plurality of lamp strings by a plurality of led light sources (low colour rendering index led light source and red-light LED light source).See Fig. 1, it is red-light LED light source (such as the D4 in first lamp string among Fig. 1) that a led light source is arranged in each lamp string, and remaining led light source then is low colour rendering index led light source (such as D1～D3, D5 in first lamp string among Fig. 1～D12) in this lamp string.
Be mixed out the light fixture of high color rendering index (CRI) of the mode that the low colour rendering index led light source of the utility model utilization adds the red-light LED light source, to hang down colour rendering index led light source and red-light LED light source intersection and mix use, on the basis of originally low colour rendering index led light source D1～D3, D5～D12, increase red LED light source D4.Wherein, low colour rendering index led light source adopts blue light-emitting to add the fluorescent material of Yellow light-emitting low temperature, forms white light.After adding the red-light LED light source light spectrum, can greatly improve the colour rendering index of hybrid light source, and can not be subject to too large impact aspect price and the luminous flux.
The utility model in actual use, when arranging at LED lamp light source aluminium base or above the similar light source module, to intersect embedding to low colour rendering index led light source and red-light LED light source according to actual conditions, adjacent two light sources do not use the red-light LED light source simultaneously, the adding of red-light LED light source is wanted evenly, light source position and colour temperature are all mixed, the ratio that adds simultaneously the red-light LED light source can not be too large, according to the actual conditions control ratio, it is not impacted to colour temperature.
Above-described only is preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection domain of the present utility model.
