Problems solved by technology
CN201475731 announced the "LED Plant Lighting Lamp", which uses two monochromatic lights of green LED and blue LED as the main light, and uses red, yellow, green, blue, and purple lights as auxiliary light as a combined light source, and there is no far-red light LED. With the participation of ultraviolet light LED, it is difficult to obtain the R / FR ratio and the irradiation of ultraviolet light. The lamp also has the connection and combination of LED drive unit, LED control unit, sampling detection unit, communication unit and power supply unit, etc., and the structure is complex. high cost
In this technical solution, both the main light and the auxiliary light have blue light and green light, and the light colors overlap, so the goal of solving the problem is not clear

Embodiment Construction
[0011] The present invention is described in detail below in conjunction with the embodiments and with reference to the accompanying drawings: It is well known by scholars in the industry that the blue light of 400-520nm and the red light of 610-720nm, the far-red light of 720-800nm and the light of 315-400nm are mainly involved in photosynthesis. UV light also has a positive effect on plant growth. Red light regulates the assembly of photosynthetic machinery at the transcriptional level, thereby directly affecting plant photosynthesis. The regulation of photosynthesis by blue light mainly focuses on the opening of stomata, the differentiation and movement of chloroplasts, and the regulation of the activity of photosynthetic enzymes. Red light and blue light have different effects on plant growth and development. Blue light is beneficial to the growth of plant leaves, while red light promotes the elongation of plant stems. Stronger blue light will make plants form a shorter...

The invention discloses a four-color light emitting diode (LED) combined light supplement lamp. The lamp is combined by red LEDs (1), blue LEDs (2), far-red LEDs (3) and ultraviolet LEDs (4), wherein the red LEDs and the blue LEDs are alternately arranged in rows or lines; the far-red LEDs (3) and the ultraviolet LEDs (4) are alternately arranged in rows or lines; previous rows or lines and next rows or lines are alternately arranged; two adjacent LEDs with the same color are arranged in a staggering way; and if n red and blue LEDs are arranged in each row or line, the number of the far-red and ultraviolet LEDs in each row or line is n-1. In the light supplement lamp, four-color LEDs are selected and used, and an arrangement mode, density, an interval and irradiation brightness are determined, so that requirement of plants on irradiation density of each color light can be guaranteed; red / blue (R / B) and red / far-red (R / FR) ratios are reasonable and balanced; the irradiation density of each color light can be adjusted and controlled by adjusting a current or voltage value; and crops can be intermittently irradiated by matching intermittent irradiation control circuits (6, 7, 8) and an intermittent or synchronous selection circuit (9); and light can be more perfectly supplemented.
Description
technical field [0001] The invention relates to a supplementary light required for plant photosynthesis. Background technique [0002] There are many reports about plant fill lights using LEDs as light sources. Each has its theoretical basis and application value, but the application focuses and effects are different. CN100587326 announced the "light-emitting diode combination method with uniform red and blue light ratio and its module", which solved the problem of the arrangement and matching of red and blue LEDs and the uniform distribution of their luminous flux ratio (R / B), because there is no far-red Light LED participates in collocation, can not solve the uniform distribution problem of red light and far red light LED luminous flux ratio (R / FR); Three kinds of LEDs participate in the combination, taking into account both the ratios of R / B and R / FR, which is conducive to the further improvement of the photosynthetic effect, but this patented technology does not have th...
