Problems solved by technology

However, the light intensity emitted in this way will be very low, and most plants need strong light exposure
This has led to the fact that the light intensity irradiated on the plants cannot meet the needs of plant growth.
The packaging structure of plant lighting LEDs that appear now mainly uses multiple chips, and different structures can be pieced together to produce a uniform full spectrum. This is not only a waste of cost, but the structure is complex and the spectrum is unstable.

Abstract

The invention discloses an LED composite full-spectrum light source capable of promoting plant growth. Light emitted by an LED light source is irradiated to rare earth phosphor powder, and then an emission spectrum band is formed and comprises two or more emission peaks in the range of 350-1,100 nm. Quantum dot materials are added to the rare earth phosphor powder, the emission peaks of the emission spectrum band are adjusted in the full-wave band range of 350-1,100 nm through selection of quantum dot material composition elements and adjustment of particle sizes. The rare earth phosphor powder is any one or more of phosphor powder with the spectrum ranging from 350 nm to 1,100 nm. The LED composite full-spectrum light source has the effects that the photorefraction consumption rate is reduced, the light source color and luster are uniform, light polarization is avoided, the lighting effect is improved, the structure is simple and the cost is saved.

Description

technical field [0001] The invention belongs to the field of LED lamp beads, and in particular relates to an LED compound full spectrum for promoting plant growth. Background technique [0002] Light is a necessary condition for plant growth, but the intensity of sunlight varies with geographical latitude, seasons and weather conditions, so there is often insufficient light, so that the light conditions cannot meet the needs of plant growth. [0003] According to relevant data research, it can be known that the light that affects plant growth is divided into light quality (spectrum / wavelength) and light intensity (that is, light brightness and light efficiency). Such as figure 1 As shown, light with different light qualities has different effects on plant growth, and the wavelength range of 300-1100NM has a significant promotion effect on plant photosynthesis. Such as image 3 and Figure 4 As shown, light with different light intensities has different effects on plant g...
