Problems solved by technology

However, the perception of skin color is greatly affected by the lighting environment. Inappropriate lighting environment will make the perception of skin color worse and reduce its personal image.
[0004] At present, there is no lighting device on the market that aims at improving the skin color effect, making it difficult for people to guarantee the skin color perception of their skin under the light environment

Embodiment 1

[0064] In Embodiment 1, a blue LED chip with a peak wavelength of 450±5nm is provided on the illuminating device 101 as the blue light generating part, and a red light 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 the yellow-green phosphor that can convert part of the blue light emitted by the blue light generating part into yellow-green light is used as the yellow-green light generating part. 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 yellow-green light generating part. image 3 It is the relative spectral energy distribution diagram of Example 1, the blue light emitted by the blue LED chip forms the first peak, the luminous peak wavelength of the first peak is located at 450nm, and the FWHM is about 20nm. The red phosphor converts part of...

Embodiment 2

[0065] In Embodiment 2, a blue LED chip with a peak wavelength of 450±5nm is provided on the illuminating device 101 as a 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 a red light generating part. And the yellow-green phosphor that can convert part of the blue light emitted by the blue light generating part into yellow-green light is used as the yellow-green light generating part. 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 yellow-green light generating part. Figure 4 It is the relative spectral energy distribution diagram of Example 2, the blue light emitted by the blue LED chip forms the first peak, the luminous peak wavelength of the first peak is located at 450nm, and the FWHM is about 20nm. The red phosphor converts part of the blue...

Embodiment 3

[0066] In embodiment 3, a blue LED chip with a peak wavelength of 460±5nm is provided on the illuminating device 101 as the blue light generating part, and a red light 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 the yellow-green phosphor that can convert part of the blue light emitted by the blue light generating part into yellow-green light is used as the yellow-green light generating part. 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 yellow-green light generating part. Figure 5 It is the relative spectral energy distribution diagram of Example 3, the blue light emitted by the blue LED chip forms the first peak, the luminous peak wavelength of the first peak is located at 460nm, and the FWHM is about 20nm. The red phosphor converts part o...

Abstract

The embodiment of the invention discloses a light source module and a light device using the light source module. Through adjusting peak wavelengths, peak strengths and color coordinates of blue light, red light and green-yellow light in the irradiation light emitted by the light source module to the preset range, the irradiation light emitted by the light source module can improve the skin color perception of people skin.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a light source module and a lighting device using the light source module. Background technique [0002] With the rapid development of lighting technology, lighting devices have become indispensable in people's lives. People spend most of their time living in light environments, and how to improve people's images in light environments has gradually attracted attention. [0003] As an important factor of people's appearance, the perception of skin color reflects a person's health and age, and can greatly affect a person's social attractiveness. However, the perception of skin color is greatly affected by the lighting environment, and inappropriate lighting environment will make the perception of skin color worse and reduce its personal image. [0004] Currently, there is no lighting device on the market aimed at enhancing the skin color effect of the skin, which makes it difficu...
