LED plant-growth lamp with continuous spectrum

Abstract

The invention discloses an LED plant-growth lamp with a continuous spectrum. The LED plant-growth lamp comprises an LED light source lamp bead group (namely a light source), a light source base board, a radiator and a driving power source matched with the light source, wherein the LED light source lamp bead group consists of warm white light LEDs and red light LEDs. The correlated color temperature of the warm white light LEDs is below 4000K, and each warm white light LED is formed by applying fluorescent powder on a blue light chip of which the wave length of emitted light is 420-490nm; the fluorescent powder is a mixture of YAG fluorescent powder which emits yellow light at peak and fluorescent powder which emits green light at peak wavelength; the green-light fluorescent powder accounts for 5%-30% of the total weight of the fluorescent powder; the wave length of the red light LEDs is within the range of 620-680nm. The LED plant-growth lamp disclosed by the invention has the technical effects that the wave length of light is within the range of 430-680nm, and the lamp has the continuous spectrum so that the requirements of plants for light with other wave lengths can be met; the light supplementing effect is good; the growth quality of plants is high. The LED plant-growth lamp saves energy and is low in production cost.

Description

technical field [0001] The invention relates to an LED plant growth lamp, in particular to an LED plant growth lamp with continuous spectrum. Background technique [0002] Light is a necessary condition for green plants to realize photosynthesis, and light is needed in all stages of plant germination, growth, flowering, and fruit formation. For tens of millions of years, green plants have absorbed energy from sunlight to achieve light and function. Sunlight is a continuous spectrum of light. According to the needs of each stage of life, different plants intercept the light of required wavelengths from sunlight, not only blue light and red light, but also a small amount of light of other wavelengths. [0003] The emergence of facility agriculture and modern agricultural factories has raised the demand for artificial light sources for plant growth. The light needed for plant photosynthesis has a wavelength between 400 and 700 nanometers (nm); while blue light with a wavel...

But this kind of red and blue light combination plant growth lamp, because it does not have a continuous spectrum, it can only play a good role in promoting the growth of plants in certain growth stages of plants, but it cannot meet the needs of plants for other wavelengths of light. , resulting in the lack of some nutrients, affecting the quality
