Abstract
The utility model discloses an LED (Light Emitting Diode) light source module with a high color-rendering index and a high light efficiency. Specifically, the LED light source module with a high color-rendering index and a high light efficiency comprises an LED circuit board and LED lamp beads fixed on the LED circuit board, wherein the LED lamp beads consist of white light lamp beads, red light lamp beads and green light lamp beads, and the number ratio of the white light lamp beads to the red light lamp beads to the green light lamp beads can be 6:2:1. The LED light source module with the high color-rendering index and the high light efficiency has the beneficial effect that the aims of high color-rendering index, high light efficiency, flexibility and changeability are achieved through a manner that the white light, red light and green light LED lamp beads with ordinary color-rendering indexes are adopted to be arranged in a mixing way according to a certain ratio. Due to the addition of red light and green light, the light-emitting spectra of an LED lamp can be richer, the color-rendering index can be increased to be over 85 from 70, and the color reduction is truer; and meanwhile, the red light and the green light have certain brightness, so that the influence on light efficiency is little.
Description
Technical field
The utility model relates to the LED light fixture, and relates more specifically to a kind of high color rendering index and high illumination efficiency led light source module.
Background technology
In recent years, at lighting field, energy saving and environment friendly light fixture more and more receives publicity, especially the LED light fixture.According to the parameter index of national room lighting, the colour rendering index of light source must reach more than 80.Along with the LED continuous advancement in technology, white light LEDs has been obtained significant progress at aspects such as light efficiency, life-span and costs.Present led light source module on the market uses the mode of the white light LEDs of high color rendering index (CRI) to improve colour rendering index more.Though this mode colour rendering index is higher, light efficiency decreases.Therefore, desired is a kind of led light source module that colour rendering index does not influence light efficiency simultaneously that improves.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of high color rendering index and high illumination efficiency led light source module.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of high color rendering index and high illumination efficiency led light source module; Comprise the led circuit plate and be fixed on the LED lamp pearl on the led circuit plate, LED lamp pearl comprises white light pearl, red globe lamp pearl and green glow lamp pearl.
As preferably, the number ratio of white light pearl, red globe lamp pearl and green glow lamp pearl is 6:2:1.
Compared with prior art, the advantage of the utility model is: the white light that adopts common colour rendering index mixes in certain proportion to arrange with ruddiness and green light LED lamp pearl and reaches high color rendering index (CRI), high light efficiency, the purpose of flexibility and changeability.Because the adding of ruddiness and green glow is arranged, make more horn of plenty of the luminous spectrum of LED lamp, can colour rendering index be brought up to more than 85 from 70, the color reduction is more true, and while ruddiness and green glow also have certain brightness, so very little to the influence of light efficiency.
Description of drawings
Fig. 1 illustrates the sketch of arranging according to the LED lamp pearl of the embodiment of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As a kind of embodiment of the utility model, a kind of high color rendering index and high illumination efficiency led light source module comprises the led circuit plate and is fixed on the LED lamp pearl on the led circuit plate.LED lamp pearl comprises white light pearl 1, red globe lamp pearl 2 and green glow lamp pearl 3.In the accompanying drawings, the number ratio of white lamps pearl 1, red colored lamp pearl 2 green light pearls 3 is 6:2:1, but also can use other ratio according to the difference of LED.Referring to Fig. 1, it shows the LED lamp pearl arrangement mode according to the utility model embodiment.In the figure, 9 LED lamp pearls are arranged on the led circuit plate, and wherein white led lamps pearl 1 is 6, and red LED lamp pearl 2 is 2, and green LED lamp pearl 3 is 1.In addition, 9 LED lamp pearls are arranged to the array of 3 X 3, and in this array, white lamps pearl 1 is arranged in the left and right sides, and green light pearl 3 is arranged in the center of this array, and red colored lamp pearl 2 is arranged in the two ends up and down of green light pearl 3.Like this, the number ratio of white lamps pearl 1, red colored lamp pearl 2 green light pearls 3 is 6:2:1, thereby but reaches high color rendering index (CRI), high light efficiency, the purpose of flexibility and changeability.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
