In some embodiments of the present invention, the fixing ring 400 is disposed on the substrate 100, and the fixing ring 400 is integrally formed with the substrate 100, the fixing ring 400 is disposed around the fixing groove 110, and the fluorescent glue 300 includes: a fluorescent layer (not shown) and a glue layer (not shown), wherein the fluorescent layer covers the light emitting chip 200 and is located in the fixing groove 110; the glue layer is adhered to the phosphor layer, and fixes the phosphor layer on the substrate 100, the glue layer being located in the fixing ring 400. The fluorescent layer is a layer formed by fluorescent powder, and is mixed with the fluorescent powder through a glue layer to obtain the fluorescent glue 300, and the fluorescent layer and the glue layer are fixedly connected and cannot be separated, so that the fluorescent glue 300 is stably installed on the substrate 100. Therefore, the fluorescent layer is disposed in the fixing groove 110, the glue layer is disposed in the fixing ring 400, and the glue layer fixes the fluorescent layer on the substrate 100. by disposing the fixing ring 400, the glue layer is restricted from flowing out before dropping glue for molding, so that the glue layer completely covers the fluorescent layer and the light emitting chip 200, and the fluorescent glue 300 can mix all lights emitted from the light emitting chip 200 to emit uniform lights. In some embodiments of the present invention, the fluorescent layer is disposed in the fixing groove 110 flush with the surface of the substrate 100, and the glue layer is disposed in the fixing ring 400 flush with the surface of the fixing ring 400.

Particularly, researches find that the combination of the red and blue LEDs has positive influence on the growth and development of tissue culture plants, and is superior to monochromatic light treatment. As found in Hahn and other researches, the rehmannia glutinosa tissue culture seedlings treated by a single red light LED or a blue light LED grow excessively, but grow robustly under the red and blue LED composite light. It is believed that the combination of red and blue LEDs can increase plant growth and development by increasing the net photosynthetic rate because the spectral energy distribution of red and blue light is consistent with the chlorophyll absorption spectrum. Therefore, when the plant lighting source works, the current is firstly transmitted into the first LED210 and the second LED220 which are uniformly distributed and have different wavelengths and are arranged on the substrate 100, so as to generate uniform light rays with different wave bands, and the uniform light rays are emitted into the fluorescent glue 300, wherein fluorescent powder with red and yellow primary colors is uniformly mixed in the fluorescent glue 300. When the light emitted by the first LED210 and the second LED220 passes through the fluorescent layer formed by the fluorescent glue plate 300, the red fluorescent powder and the yellow fluorescent powder which are uniformly mixed in the fluorescent glue 300 are respectively excited, and since the red fluorescent powder and the yellow fluorescent powder are uniformly mixed in the gel in advance, electrons jump to higher-level light after receiving the energy of photons in the LED light, so that uniform light mixing is realized. According to the utility model discloses plant lighting source, through first LED210 and the second LED220 that set up different wavelengths on base plate 100, provide the light source of suitable colour for each stage of vegetation to set up fluorescent glue 300 simultaneously on first LED210 and second LED220, carry out the fluorescent layer to the light that a plurality of LED luminescence chip 200 produced and mix the light, what messenger plant lighting source sent can the misce bene, more is favorable to the plant normal growth.

In some embodiments of the present invention, the first LED210 includes a blue chip with a wavelength of 430nm or 450nm and a red chip with a wavelength of 640nm or 660 nm.

In particular, photosynthesis of plants requires light, and the main carrier is chlorophyll. Chlorophyll a has absorption spectrum peaks at 430nm and 660nm in the blue-violet region, and chlorophyll b has absorption spectrum peaks at 450nm and 640nm in the blue-violet region, so that the spectrum required for photosynthesis of plants can be provided by using a blue-violet chip at 430nm or 450nm and red light at 640nm or 660 nm.

In some embodiments of the present invention, the second LED220 includes a red chip with a wavelength of 660nm and a far-red chip with a wavelength of 730 nm.

Specifically, in order to be able to perceive and respond to changes in the light intensity, light quality, light direction and light cycle of the surrounding environment, plants have evolved a photoreceptive system (photoreceptor). The photoreceptors are the key to the plant's perception of the external environmental changes, and in the plant's light response, the most important ones are the red/far-red absorbing chlorophyll and the phytochromes (phytochromes). The photosensitive pigment is a kind of pigment protein which has reversal effect on red light and far-red light absorption, participates in photomorphogenesis and regulates plant development, is extremely sensitive to red light (R) and far-red light (FR), and plays an important regulation role in the whole growth and development process from germination to maturity of plants. Phytochromes in plants exist in two more stable states: red light absorption type (Pr660nm) and far-red light absorption type (Pfr 730 nm). The two light absorption types can be mutually reversed under the irradiation of red light and far-red light. Phytochrome-related studies have shown that phytochrome (Pr, Pfr) effects on plant morphology include seed germination, de-yellowing, stem elongation, leaf expansion, shade avoidance, and flowering induction. Therefore, the second LED220 uses red light chips with the wavelength of 660nm and the wavelength of 730nm, not only to provide the spectrum required for photosynthesis, but also to control the whole process from germination to growth to flowering of plants.

In some embodiments of the present invention, different red and blue wavelength chips have the following schemes of collocation and combination according to the different spectra required by plants:

the following schemes of collocation combination exist for the first LED210 and the second LED 220:

B＝430-460DR＝650-670nm FR＝720-740nm U＝380-430nm

In some embodiments of the present invention, the bonding pad of the substrate 100 is ni-pd-au.

Specifically, after chemically precipitating nickel, adding a chemical palladium precipitation process, and isolating attack of gold precipitation liquid on a nickel layer by using a palladium layer; meanwhile, the palladium layer has higher strength and wear resistance than the gold layer, the effect of chemical deposition of thick gold can be achieved by utilizing the thin palladium layer and the thin gold layer, and the occurrence of black pads is effectively avoided. Compared with other processes such as oxidation resistance (OSP), nickel gold (ENIG) and the like, the method adopting nickel palladium gold (ENEPIG) has the following advantages:

1. the 'black nickel problem' is prevented, and the phenomenon that gold is replaced to attack the surface of nickel to form grain boundary corrosion is avoided.

2. The chemical palladium plating can be used as a barrier layer, and the problem that copper migrates to a gold layer to cause poor soldering tin performance is avoided.

3. The electroless palladium plating layer can be completely dissolved in the solder, and no high phosphorus layer can be generated on the alloy interface. Meanwhile, when the chemical plating palladium is dissolved, a new chemical plating nickel layer is exposed to generate good nickel-tin alloy.

4. Can resist multiple lead-free reflow soldering cycles.

5. Has excellent bonding property of gold wire (bonding).
