Problems solved by technology

[0009] The scale effect of light supplement equipment can only be achieved by batch research and development, manufacturing and sales, and the demand for supplement light is indeed ever-changing. The contradiction between these is that all current designs cannot solve
Although manual operation can achieve rough lighting requirements according to the application, it requires each

Embodiment Construction

[0052] The dimmable light source part includes three LED wick templates and three dimming power supplies, which are connected one-to-one. The wick module uses CREE LED wicks with wavelengths of 650m, 520nm, and 450nm. The dimming power supply uses a DC driver chip PT4207 that supports PWM dimming. The dimming power supply adjusts the output current according to the duty cycle of the PWM signal, and then adjusts the output luminous flux of each wavelength.

[0053] The height adjustment part pulls up and down the dimmable light source through a motor and a steel wire rope. The motor is controlled by the intelligent control part, and it also supports manual lifting operation.

[0054] In the intelligent control part, the central processing unit adopts MC80F7708, the memory adopts 24LC16 external Flash, the lighting time statistics adopts the "method of counting lighting time of lighting equipment in an unstable environment", and the execution module of the biological growth li...

Abstract

The invention discloses a method and a system for light supplement control of biological growth. The invention relates to the technical field of illumination and the field of plant cultivation and animal feeding. The system comprises four entity parts of an adjustable light source part, a height adjusting part, an intelligent control part and a characteristic parameter list downloading part, and a biological growth light characteristic parameter list. Equipment can operate automatically according to the characteristic parameter list downloaded at any time. By the invention, a biological researcher can research the ever changing biological light supplement independently; equipment manufacturers can research and develop, manufacture and sell universal equipment in batches; and during operation, the equipment operates automatically according to the downloaded research data. By the invention, the science, economy and popularization of the light supplement of the biological growth are improved.

Description

technical field [0001] The invention relates to the field of lighting technology, plant cultivation and animal feeding. Background technique [0002] Light can promote the growth and development of living things. Different organisms have different needs for light, and the same organism has different requirements for light at different stages of growth. Different stages have different requirements for light of different wavelengths. For example, red light can promote the growth of sweet potatoes, but inhibit the growth of sweet potatoes. The growth of grapes; giving 16 hours of comprehensive light during the slaughter period of ducks can improve meat quality. [0003] 00107943.3 describes plant lights with specific spectral wavelengths designed for plant growth. Plant lights are composed of red and blue with specific wavelengths according to a certain design. What the patent claims is the optoelectronic composition of the lighting part. [0004] 200720171735.6 describes an...
