Abstract

The invention discloses an LED light source and an LED lamp. The LED lamp comprises an LED light source; the LED light source comprises a substrate and LED lamp beads arranged on the substrate; the substrate is circular; a circuit is arranged on the reverse side of the substrate and used for communicating the LED lamp beads; 16 positions are arranged on the substrate and used for sticking the LED lamp beads; the LED lamp beads are divided into two types, namely white LED lamp beads and red LED lamp beads; the 16 positions on the substrate are divided into 4 groups; 3 white LED lamp beads and 1 red LED lamp bead are arranged in each group of positions, and 1 red LED lamp bead is pasted among 3 white LED lamp beads; the white LED lamp beads and the red LED lamp beads are used together, the proportion of each color in the traditional white light spectrum is changed, and importantly, the red spectral ratio is increased, and therefore, the color-rendering index can be increased to be greater than 90 and the application range of white light illumination can be expanded.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED light source and an LED lamp. Background technique [0002] LED lamps, or LED lighting in general, are well known in the art and are commonly used today in a wide variety of lighting applications. In addition to being very small in terms of size, so-called high-power LEDs offer a high luminous flux and are very energy-efficient. [0003] As the penetration rate of LED lighting products in people's daily life increases and the scope of application becomes wider and wider, people have new requirements for lighting, especially the light source of indoor lighting. For indoor lighting fixtures, not only must good lighting effects be obtained, but also further requirements are placed on lighting comfort and color rendering. Therefore, in terms of light source packaging, it is necessary to improve the color rendering index of the light source. LED has the advantages of small size, l...
