Abstract

The invention discloses a high cyan light LED illuminant component. The high cyan light LED illuminant component comprises a carrier body. The carrier body is provided with an electric connecting structure, at least one set of illuminant structure and a reflection cup. The illuminant structures are arranged in the reflection cup and are connected with the electric connecting structure. The illuminant structures comprise white light illuminant bodies and red light illuminant bodies. The white light and red light are mixed to obtain near-natural light. The relative spectral power of cyan light in the near-natural light is greater than 0.30. The relative spectral power of blue light is less than 0.75. According to light emitted by the light source, the relative spectral power of the cyan light is enhanced, and therefore the color rendering index rises, especially the color rendering index of R12 rises, and color rendering is improved. The relative spectral power of the blue light is lowered, and eyesight protection is facilitated, especially eyesight of young children. Sub-health due to high blue light can be reduced. Structure is simple, size is small, and application is flexible.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a high-brightness LED light-emitting element and lighting equipment including the light source. Background technique [0002] LED light source is a commonly used device in the lighting field. The existing commonly used LED light source is a white light source that uses a blue light chip combined with phosphor powder, such as Figure 12 In the spectrum shown, the light source with this structure has a high proportion of blue light and a very low proportion of blue light, which is quite different from the spectrum of natural light. The other is a white light source that uses a combination of red, green and blue chips, such as Figure 13 In the spectrum shown, this white light has three peaks in the red, green, and blue bands. The proportion of blue light is higher, the proportion of blue light is lower, and the proportion of other parts is too low, which is more different from the spe...
