Embodiment 2

[0070] In Embodiment 2, the light source module 104 is provided with a blue LED chip with a peak wavelength of 450±5nm as the blue light generating part, and a red phosphor that can convert part of the blue light emitted by the blue light generating part into red light is used as the red light generating part , And a green phosphor that can convert part of the blue light emitted by the blue light generating part into green light as the green light generating part. In this embodiment, the blue LED chip serves as the blue light generating part and the excitation light source for the red light generating part and the green light generating part. Figure 4 For the relative spectral energy distribution diagram of Example 2, the blue light energy emitted by the blue LED chip forms the first peak in the figure with a light emission peak wavelength of 450 nm, and a half-width FWHM of 21.8±5 nm. The green phosphor converts part of the blue light emitted by the blue LED chip into green li...

Abstract

The invention relates to a light source module and a lighting device comprising the same. By adjusting the peak wavelength, the peak intensity and the chromaticity coordinate of blue light, red light and green light in irradiation beams emitted by the light source module to be within a preset range, the irradiation beams emitted by the light source module is enabled to have specific spectrum distribution, not only is the evaluation of the color theory on the lighting effect considered, but also the influence of the spectrum on the actual lighting effect is considered, and meanwhile the influence of the luminescent material on the spectrum is also considered, so that the light source having a similar effect compared with sunlight and the advantages of high comfortableness, preference, color rendering index and color gamut index is obtained.

Description

Technical field [0001] The invention relates to a light source module and a lighting device comprising the light source module. Background technique [0002] With the advent and development of the third lighting technology revolution, LED lighting appliances are widely used, and people's light quality of LED lighting is getting higher and higher. The current lighting market, especially after entering the LED era, has become increasingly homogenized. In the case of homogenization, in addition to one-sided emphasis on improving light efficiency, it is serious low-price competition. At the same time, European and American countries are still reluctant to abandon traditional light sources such as incandescent lamps and tungsten halogen lamps. This is mainly because LEDs are temporarily unable to achieve the light quality of traditional light sources and have inherent defects in comfort and color rendering. The current LED products have outstanding problems in consumer perception. ...
