An LED spectrum generator, comprising an aluminum alloy shell (1), an aluminum-based circuit board (2), LED lamps (3) and a tempered glass diffuser (4); the aluminum alloy shell (1) is an inverted trapezoidal groove; high light reflecting boards (5) are laid on groove walls on the two sides of the aluminum alloy shell; the aluminum-based circuit board (2) is installed at the bottom of the inverted trapezoidal groove; a notch is enclosed by the tempered glass diffuser; the LED lamps (3) comprise R, Y, B tri-color lamps, and the tri-color lamps are arranged at intervals on the aluminum-based circuit board (2). The LED spectrum generator is designed according to the requirements for rice seedling growth, can provide rice seedling growth with weak light irradiation in specific spectrum wavebands under a weak light environment, providing an optimum spectrum ingredient for sexual propagation of the rice seedlings in the earing stage, thus effectively improving the sexual propagation ratio and ear setting ratio of the rice seedlings, improving rice seedling and propagation quality, and the generator has a simple structure, portability and good heat dissipation effect. |
