Problems solved by technology

[0004] However, the above-mentioned prior art does not provide a corresponding specific production method for the light source or its device in any of the embodiments described above, so it is impossible to provide production guidance for scale production, and the provided light source with a full wavelength range The light source still has technical problems such as uneven luminous color and weak luminous intensity
In addition, its production process is relatively complicated, with high design and production costs
Secondly, when semiconductor chips are packaged, the dispensing pitch is often fixed, which makes the dispensing flexibility poor, and thus leads to uneven distribution of colloids between semiconductor chips or large differences in the structure after dispensing

Abstract

The invention relates to a device for preparing a light source. The device at least comprises a distribution module, a detection module and a control module, wherein the distribution module is used for distributing a fluorescent glue onto first semiconductor chips having an emission peak wavelength of 360-490 nm and / or second semiconductor chips having an emission peak wavelength of 700-800 nm, and / or obtaining the area and / or size of the corresponding glue points distributed to the first semiconductor chips and / or the second semiconductor chips; the detection module is used for measuring light emitting characteristics of light emitted by a plurality of first semiconductor chips and / or second semiconductor chips distributed with the fluorescent glue; and the control module is used for calculating schematic values about the light emitting characteristics of at least one first semiconductor chip and / or second semiconductor chip according to the light emitting characteristics measured by the detection module, adjusting the distribution amount of the distribution module to the fluorescent glue based on the schematic value, and / or adjusting the distribution amount of the distribution module to the fluorescent glue based on the glue point area and / or size obtained by the distribution module, and controlling the movement of the distribution module so as to adjust the glue dispensing gap.

Description

technical field [0001] The invention relates to the technical field of photobiological effects, in particular to a device for preparing a light source and a lamp made of the light source. Background technique [0002] As a new type of light source, LED has been widely used in the field of lighting, but with the improvement of people's quality of life, it is no longer simply to pursue high luminous efficiency to meet basic lighting needs for LED light sources, but more to pursue for The impact on human health, visual experience and work efficiency. Most commercially available LED light sources have a low color rendering index, and the impact of the light source on human health has not been considered too much, especially the impact of the light source on human non-visual biological effects. Long-term exposure to such a light source will affect the human body There is a certain hazard to health. [0003] CN111140774A discloses a novel light source capable of suppressing exce...
