Patent ID: 11297775

Abstract:
A LED grow light array and method for controlling thereof, aimed at increasing plant canopy light penetration without stationary hot spots, providing antimicrobial light to eliminate microorganism on plants, providing pulsing canopy penetrating and microbial light without a dark period, and reducing energy consumption, the LED grow light array comprising: a LED grow light array, the array comprising at least four light bars, wherein the light bars comprise discrete photosynthetic LED chips of different types based on the wavelength of light they emit, the light they emit being either blue, red, or white light, or a combination thereof, wherein blue light wavelength ranges from 405 nm to 450 nm, red light wavelength ranges from 630 nm to 720 nm, and white light is a combination of wavelengths that ranges from 400 nm to 700 nm, each type of photosynthetic LED chip forming a set of chips; wherein the bars are in a series and spaced evenly over a given plant growing area; wherein the light bars further comprise discrete antimicrobial LED chips of different types based on the wavelength of light they emit, the light being light with antimicrobial properties between the wavelengths of 100 nm and 405 nm, each type forming a set of chips; wherein each light bar comprises a circuit board to mount said discrete photosynthetic and antimicrobial LED chips thereon; at least one LED driver to provide power to the LED chips; at least one microprocessor to control the at least one LED driver; and a lighting program sent to the microprocessor designed to control the at least four light bars and the sets of photosynthetic and antimicrobial LED chips individually.
