Embodiment 1

[0068] Embodiment 1, in the light source module 104, the first light-emitting element 1041 is a blue LED chip with a peak wavelength of 450±5 nm, which serves as a blue light generating part. The first additional luminous body 1042 is LuAG green phosphor powder in aluminate system, which can convert part of the blue light emitted by the blue light generating part into green light as the green light generating part. The second additional luminous body 1043 is a nitride red phosphor CaAlSiN3:Eu, which serves as a red light generating part and can convert part of the blue light emitted by the blue light generating part into red light. In this embodiment, the blue LED chip not only serves as the blue light generating part, but also serves as the excitation light source for the red light generating part and the green light generating part. figure 2It is the relative spectral energy distribution diagram of Example 1. The blue light energy emitted by the blue LED chip forms the firs...

Embodiment 2

[0069] Embodiment 2, the first light emitting element 1041 in the light source module 104 is a blue LED chip with a peak wavelength of 450±5 nm, which serves as a blue light generating part. The first additional luminous body 1042 is a silicate green phosphor, which, as a green light generating part, can convert part of the blue light emitted by the blue light generating part into green light. The second additional luminous body 1043 is a nitride red phosphor CaAlSiN3:Eu, which serves as a red light generating part and can convert part of the blue light emitted by the blue light generating part into red light. In this embodiment, the blue LED chip not only serves as the blue light generating part, but also serves as the excitation light source for the red light generating part and the green light generating part. Figure 4 It is 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....

Embodiment 3

[0070] In Embodiment 3, the first light emitting element 1041 in the light source module 104 is a blue LED chip with a peak wavelength of 450±5 nm, which serves as a blue light generating part. The first additional luminous body 1042 is GaYAG green phosphor powder in aluminate system, which can convert part of the blue light emitted by the blue light generating part into green light as the green light generating part. The second additional luminous body 1043 is a nitride red phosphor CaAlSiN3:Eu, which, as a red light generating part, can convert part of the blue light emitted by the blue light generating part into red light. In this embodiment, the blue LED chip not only serves as the blue light generating part, but also serves as the excitation light source for the red light generating part and the green light generating part. Figure 6 It is the relative spectral energy distribution diagram of Example 3, the blue light energy emitted by the blue LED chip forms the first pea...

Abstract

The invention provides a light source module and a lighting device comprising the light source module. A specific light color is achieved in a specific fluorescent powder proportion, the assessment of the color theory on the lighting effect and the influence of spectrums on the actual lighting effect are both considered, meanwhile, the influences of luminescent materials on the spectrums are considered, and a light source is obtained, wherein the light source is high in comfort, high in preference and high in color rendering index and color gamut index, and compared with the sunlight, the effect of the light source is similar to that of the sunlight.

Description

technical field [0001] The invention relates to a light source module and a lighting device including 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. At present, the lighting market, especially after entering the LED era, is increasingly homogeneous. In the case of homogeneity, 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 unwilling to abandon traditional light sources such as incandescent lamps and tungsten-halogen lamps. The current LED products have outstanding problems in consumer perception. [0003] In response to this situation, we urgently need to research and find white LED light sources that are more comfortable, have higher color rendering, and can matc...
