Embodiment 1

[0028] see figure 1 Now, the monochromatic LED 100 for plant lighting provided by Embodiment 1 of the present invention will be described. The monochromatic LED 100 for plant lighting includes a substrate 11, a blue chip 13 and a fluorescent glue layer 14; the blue chip 13 is mounted on the substrate 11 and electrically connected to the substrate 11 to support the blue chip 13 through the substrate 11, And after being powered on, the blue light chip 13 emits blue light; and the fluorescent adhesive layer 14 is packaged on the blue light chip 13 to protect the blue light chip 13 . Fluorescent adhesive layer 14 includes encapsulation glue and phosphor powder mixed in the encapsulation glue; the encapsulation glue plays a role in bonding and curing, and protects the blue chip 13; When it enters the phosphor, it will be excited to produce light of its own wavelength. Specifically, the fluorescent powder includes fluoride red powder and nitride red powder, that is, the phosphor p...

Embodiment 2

[0048] see figure 2 The difference between the monochromatic LED 100 for plant lighting in this embodiment and the monochromatic LED for plant lighting in Embodiment 1 is:

[0049] In this embodiment, the lens layer 15 has a spherical shape for better dimming, so as to increase the light output angle of the monochromatic LED 100 for plant lighting, which is convenient for plant lighting. Of course, in some other embodiments, the lens layer 15 can also be set in other shapes as required.

[0050] Other structures of the monochromatic LED 100 for plant lighting in this embodiment are the same as those of the monochromatic LED for plant lighting in Embodiment 1, and will not be repeated here.

[0051] The embodiment of the present invention also discloses a plant lighting lamp; please refer to figure 1 and figure 2 , the plant lighting lamp includes the above-mentioned monochromatic LED 100 for plant lighting. The plant lighting lamp uses the above-mentioned monochromatic L...

Abstract

The invention provides a monochrome LED for plant illumination and a plant illumination lamp. The monochrome LED for plant illumination includes a substrate, a blue light chip and a fluorescent adhesive layer. The fluorescent adhesive layer includes package adhesive and fluorescent powder mixed in the package adhesive. The fluorescent powder includes fluoride red powder and nitride red powder. Thechemical formula of the fluoride red powder is K<2>Si<x>Mn<1-x>F<6>, wherein 0.05<=x<=0.1. The chemical formula of the nitride red powder is SrEuCa<1-a-b>AlSiN<3>, wherein 0.05<=a<=0.1, and 0.008<=b<=0.08. By mixing the fluoride red powder and the nitride red powder into the fluorescent powder and using the blue light chip to excite the fluorescent powder, monochrome illumination light witha wide spectrum range can be obtained, and monochrome light can be supplemented to plants to promote the growth of plants.

Description

technical field [0001] The invention belongs to the field of LED plant lighting, and more specifically relates to a monochromatic LED for plant lighting and a plant lighting lamp using the monochromatic LED for plant lighting. Background technique [0002] Light-Emitting Diode (English: Light-Emitting Diode, referred to as LED). The growth of indoor plants such as plant factories and greenhouses requires light supplementation for plant growth. And because LED lights have the characteristics of high light output rate, energy saving and long life, they are more and more applied to plant lighting. Since plants generally require a wide range of light wavelengths, current plant lighting generally uses a combination of multiple LEDs that generate light of different wavelengths to simulate sunlight to illuminate plants. However, in order to better promote plant growth, it is often necessary to enhance the light of a certain color. At this time, monochromatic LEDs are often requi...
