Abstract

The invention relates to the technical field of illuminating, in particular to an LED light source imitating spectrum of sunlight. The LED light source comprises a light emitting module which is composed of a single light emitting chip or a plurality of same or different light emitting chips, wherein wavelength of the light emitting chip ranges from 260 to 1100nm; a bracket is used for fixedly installing the light emitting chip; a fluorescent glue packages the light emitting chip, so that light emitted by the light emitting chip emits after penetrating the fluorescent glue, and the fluorescent glue is composed of silica gel, epoxy resin adhesive or other mixed fluorescent powder; the fluorescent powder consists of several components selected from aluminate fluorescent powder, silica-aluminum nitride fluorescent powder, oxynitride fluorescent powder, fluoride fluorescent powder, chlorophosphate fluorescent powder and nitride fluorescent powder. The LED light source achieves full spectrum based on the light emitting chips of different chip wavelengths and sizes under the condition of different fluorescent powder materials through different proportions, is low in energy consumption and high in energy efficiency, and is formed through research and development based on health requirement and energy conservation of people.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED light source. Background technique [0002] LED (Lighting emitting diode) lighting technology has been welcomed for its high luminous efficiency, good impact and shock resistance, high reliability, long life, and easy adjustment, and has become a widely used lighting technology. However, the conventional LED light source is a point light source with a narrow spectrum, and its peak wavelength is between 450 and 460nm, which is very different from the sunlight spectrum. However, the special structure of the human eye and the long-term living environment of human beings determine that human beings can read and observe in sunlight. The eye has the highest sensitivity, and to make the human eye feel comfortable in a certain lighting environment, it needs to make its luminous spectrum close to the sunlight spectrum. [0003] The current white light LED mainly uses "blue light ...
