Horticultural lighting has been used as a complement to, or replacement for, sunlight as a stimulant for plant development for many years. While several light sources have been employed, most supplementary and replacement illumination for plant development in professional, large-scale operations is provided by high intensity discharge (HID) lamps.
Because of the popularity of HID lighting, there are specialized chemistries of high pressure sodium and metal halide lamps made specifically for grow lighting. Since the commercialization of LEDs in lighting, attempts have been made to create LED plant growth lighting that uses the direct colors and relative adjustability of LED spectrums to try and optimize the light to the plant’s absorption.
Significant advancements in LED system efficiency have boosted the feasibility of LEDs as an output light source alternative to HID lamps, and the widespread usage of LEDs in general lighting has driven improvements in drivers and cost reductions.
Some potential benefits of LED characteristics for the horticultural industry include the ability to develop a spectral power that is tuned to the specific crop grown and adjusted over the plant’s life cycle, as well as the potential to have greater influence over the quality of the finished product by adjusting the light. When combined with the ability to guide the LEDs and the goods extended lifespan, the potential for greenhouses is tremendous.
Most individuals understand the notion of light output and intensity, but understanding is mostly from the standpoint of photopic vision. This is based on the average human eye reaction (known as the photopic curve), with parameters like lumens and lux weighted accordingly.
The photometric curve peaks in the yellow-green area and drops off towards the blue and red ends of the spectrum; however, because plants do not have eyes, this response curve is inapplicable to them.
Rather than using the photopic response curve as a reference, horticulture lighting uses the photosynthetic response area (also known as Photosynthetically Active Radiation, or PAR) as a more appropriate reference.
Furthermore, while photosynthesis is an essential part of horticulture lighting, it is not the only function in plants that requires a spectrum of light. Additional photoreceptor responses can influence plant development characteristics, and some of these have responses that extend beyond the photosynthetically active range of wavelengths, into the UV and far-red areas.
Using a single curve and weighting the light according to a curve makes no sense since plants have varied reactions and other processes that impact plant development.Since the invention of electric lights, artificial illumination has been utilized to augment plant growth. Early research centered on carbon-arc lights, but incandescent bulbs eventually took control.
When discharge lamps first became commercially available, they were employed to varying degrees of success, and the industry eventually decided on high pressure sodium and metal halide lamps for supplementary lighting. Fluorescent lights, which employ phosphors to tune the spectrum more towards plant development, have also been used in some instances for a wider spectrum of light.
The issue with existing technology is that it is pretty stagnant. The spectrum cannot be adjusted when plant development requirements vary without manually changing out a light, which adds labor.
High pressure sodium lamps are inexpensive, energy efficient, and long-lasting, however they only give a narrow spectrum for growth, primarily in the orange and red ranges.
