The LED plant lamp adopts the technical scheme that the LED plant lamp based on the chlorophyll absorption spectrum feature design comprises a light emitting body, a casing, a power source, a first controller, a second controller and wiring terminals, wherein the light emitting body is provided with a first LED light source module and a second LED light source module, the first LED light source module is used for outputting spectrum which is matched with absorption curve spectrum features of chlorophyll a, the second LED light source module is used for outputting spectrum which is matched with the absorption curve spectrum feature of chlorophyll b, the first controller is arranged in the casing, is electrically connected with the power source and is used for controlling the light emitting intensity of the first LED light source module, the second controller is arranged in the casing, is electrically connected with the power source and is used for controlling the light emitting intensity of the second LED light source module, and each wiring terminal is arranged on the casing, and is used for electrically connecting the corresponding controller and the corresponding LED light source module. The LED plant lamp has the advantages that the growth of plants is well promoted, the light intensity of different LED light source modules can be conveniently adjusted, and the requirements of different plants are met.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an LED plant lamp designed based on chlorophyll absorption spectrum characteristics. Background technique [0002] Chlorophyll is the main pigment for photosynthesis in plants. Chlorophyll absorbs most of the red light and blue light but reflects green light, so chlorophyll appears green. It plays a central role in the light absorption of photosynthesis, including chlorophyll a, b, c, d , f and prochlorophyll and bacteriochlorophyll and so on. The chlorophyll in the chloroplasts of higher plants mainly includes chlorophyll a and chlorophyll b. The absorption spectrum of chlorophyll in the visible light band has a significant absorption peak at blue light and red light, and the position of the absorption peak varies with the type of chlorophyll. For example, the maximum absorption peaks of chlorophyll a appear around 430 nm and 670 nm, respectively; the maximum absorption peaks of chlor...

Problems solved by technology

However, this kind of LED plant light is relatively poor in versatility, and there is a large loss of red and blue energy, especially when the red and blue chip technology is improved and the output light characteristics of the chip are changed, it is difficult for the technical solution to ensure the stability of the lamp performance through simple arrangement. sex

At the same time, the simple choice of red and blue cannot match the absorption difference between different chlorophylls, it is difficult to achieve effective absorption selection, and it cannot meet the different absorption needs of different plants with different chlorophyll a and chlorophyll b ratios
