Embodiment 1
[0037] See figure 1 , figure 1 Provide a kind of LED system structure schematic diagram for promoting plant growth for the present invention, it comprises:
[0038] controller;
[0039] The first drive circuit, the second drive circuit and the third drive circuit are all electrically connected to the controller;
[0040] a first LED module, electrically connected to the first drive circuit;
[0041] a second LED module electrically connected to the second drive circuit;
[0042] a third LED module, electrically connected to the third drive circuit;
[0043] Wherein, the wavelengths of light emitted by the first LED module, the second LED module and the third LED module are different.
[0044] Further, on the basis of the above embodiment, the first LED module is a red LED module, the second LED module is a blue LED module, and the third LED module is a yellow LED module.
[0045] In one embodiment, the LED system provided by the present invention further includes a memor...
Embodiment 2
[0060] This embodiment further limits or illustrates the implementation of the present invention on the basis of the above embodiments.
[0061] See Figure 4 , Figure 4 A schematic diagram of an LED packaging structure provided by an embodiment of the present invention, the packaging structure includes:
[0062] LED chips;
[0063] A first silica gel layer (22), coated on the LED chip;
[0064] A first lens layer (23), prepared on the first silica gel layer (22);
[0065] A second silica gel layer (24) and a third silica gel layer (25), which are successively arranged on the first lens layer (23);
[0066] A second lens layer (26), arranged on the third silica gel layer (25);
[0067] The fourth silica gel layer (27) is arranged on the second lens layer (26).
[0068] With this implementation mode, a better light-gathering effect is achieved through the multi-layer lens, which is very suitable for use on plants and reduces light waste. Preferably, the LED chip of the ...
Embodiment 4
[0077] This embodiment further describes the LED package structure and its manufacturing method in the embodiment.
[0078] See Image 6 , Image 6 A schematic diagram of an LED packaging process flow provided by an embodiment of the present invention, the method includes:
[0079] Select the LED chip;
[0080] A multi-layer silica gel layer is formed on the LED chip to realize the packaging of the LED chip, wherein the silica gel layer in contact with the LED chip in the multi-layer silica gel layer does not contain fluorescent powder.
[0081] In this embodiment, the silica gel layer in direct contact with the LED chip does not contain phosphor, and the phosphor is placed in other silica gel layers that do not directly contact the LED chip, avoiding direct contact between the phosphor powder and the LED chip. The reason for the implementation is: the chip has an absorption effect on the backscattered light, and the implementation of phosphor powder directly coated on the ...
