Method for making and using gas-delivery light fixture

Abstract

A plant-light system that includes a plurality of ducted plant-lighting plenum sheets, wherein each ducted plant-lighting plenum sheet includes a plurality of flexible perforated LED sheets, each LED sheet including a plurality of LEDs arranged on a grid, the plurality of LEDs including LEDs emitting light that appears red, light that appears blue, light that appears white, and light that is at least mostly infrared light, wherein each plant lighting sheet has a length and a width, and wherein the plurality of lighting sheets is arranged along a length of a room; a plurality of plant-holding pockets arranged along the length of the room generally parallel to the plurality of ducted plant-lighting plenum sheets; and a plant-lighting plenum sheets motion and withdrawal system arranged to move the plurality of ducted plant-lighting plenum sheets to a plurality of different locations relative to the plurality of plant-holding pockets for different time periods.

What is claimed is: 
     
         1 . A method comprising:
 providing a housing connected to a perforated circuit substrate having a plurality of electrical conductors on a first face of the circuit substrate and a plurality of perforations through the substrate and a first plurality of LEDs affixed to the plurality of electrical conductors;   delivering a gas to the housing such that the gas is emitted out through the plurality of perforations; and   delivering electrical power to the first plurality of LEDs such that light is emitted from each of the first plurality of LEDs.   
     
     
         2 . The method of  claim 1 , wherein the delivering of the gas to the housing includes using a fan to blow air into the housing. 
     
     
         3 . The method of  claim 1 , wherein the delivering of the gas to the housing includes delivering carbon dioxide from a compressed source of carbon dioxide. 
     
     
         4 . The method of  claim 1 , wherein each one of the first plurality of LEDs emits the red light with a peak wavelength in a range of 610 nm and 690 nm, inclusive, and a full-width half-maximum bandwidth of no more than 40 nm, and wherein the gas-delivery lighting apparatus further includes:
 a second plurality of LEDs affixed to the conductors, wherein each one of the second plurality of LEDs emits the infrared light with a peak wavelength in a range of 700 nm and 780 nm, inclusive, and a full-width half-maximum bandwidth of no more than 40 nm; and   a third plurality of LEDs affixed to the conductors, wherein each one of the third plurality of LEDs emits the blue light with a peak wavelength in a range of 420 nm and 480 nm, inclusive, and a full-width half-maximum bandwidth of no more than 30 nm.   
     
     
         5 . The method of  claim 1 , wherein each die of the first plurality of LED dice emits the blue light at a first intensity, wherein each die of the second plurality of LED dice emits the red light at a second intensity, wherein each die of the third plurality of LED dice emits the infrared light at a third intensity, and wherein the third intensity is between approximately 10 percent and approximately 20 percent of the second intensity. 
     
     
         6 . The method of  claim 1 , wherein the first gas conduit includes a fan housing with an electrically powered fan mounted therein. 
     
     
         7 . The method of  claim 1 , further comprising:
 a source of one or more aromatic chemicals useful for aroma therapy;   a temperature-adjustment device operatively coupled to the first gas conduit; and   a controller operatively coupled to the source of one or more aromatic chemicals, to the temperature-adjustment device, and to the conductors coupled to the first plurality of LEDs and configured to allow user control of the light, aroma therapy and gas temperature.
